In the previous article, the author introduced the appearance of thinkPad P15 Gen 1 (P15G1) and also carried out daily maintenance level disassembly, confirming the planning and design of P15G1 and ThinkPad T15g, ThinkPad P17 Gen 1 common motherboard At the same time, this MTM for 20SUS-09800 U.S. version of P15G1, although no factory without WWAN card, but comfortably reserved WWAN antenna and SIM card slot, users can add their own WWAN card, and reserved 5G antenna on the motherboard.
However, preliminary tests, can not use the standard M.2 2280 SATA SSD, the author concluded in the previous article that this WWAN card slot can not support the use of SSD In this regard, some readers have raised two questions:
1. What kind of 5G WWAN card should be used for this reserved 5G antenna interface?
2. Can I use PCIe/NVMe SSD for this WWAM card slot?
For the first question, the author is currently after querying the information, it seems that only Sierra (Siale) produced EM9190 WWAN card support 5G, its official full name is AirPrime ® EM9190 5G NR Sub-6 GHz and mmWave Module, the price of more than 3,000 yuan, the number of antenna interface is eye-popping---- up to 8!
No wonder the P15G1 reserves a dedicated 5G antenna interface in addition to four WWAN antennas
However, ThinkPad's board card has always used whitelisting, direct purchase of unofficial EM9190 WWAN card, want to be unusable, but has not yet found the official 5G WWAN card information, users in need, it is best to wait for official information as well On the left side of the figure below is the EM9190, and on the right is the WWAN antenna used by the X1C, which is marked with a red box antenna interface, similar to the 5G antenna interface reserved on the P15G1 motherboard, for informational purposes only
For the second question, the author had to take the machine down again for testing, for which the following 6 M.2 SSDs were prepared, from left to right:
Samsung SM951 M.2 2280 NVMe SSD 128GB
Samsung PM851 M.2 2280 SATA SSD 128GB
Western PC SN520 M.2 2242 NVMe SSD 256GB
2 Jinweidi (model unknown) M.2 2242 SATA SSD 256GB
The results of the tests were disappointing:
Samsung SM951 could not be installed because the interface was different;
Samsung PM851 could barely be installed, but no new hardware was found on the power-up;
Jinweidi successfully installed, but the power-on still can not identify the new hardware;
The author has high hopes for the west number PC SN520 successful installation, after power-up to identify the new hardware ---- but identified as a network card, because it is not certified, 1802 error, can not continue to start into the operating system, requires that must be shut down and removed After testing, it is almost certain that it is not possible for users to install SSDs on the WWAN of P15G1 themselves, unless there is an official M.2 2242 NVMe SSD on the whitelist
Next, the author tested the installation of SSD on the second M.2 2280 SSD slot on the P15G1, starting with the installation of M.2 2280 NVMe SSD, which performed all the best
However, when changing M.2 2280 SATA SSD, there was a 2101 error on the boot, although Esc can continue to start, but the newly installed SATA SSD could not be found into the system In this way, it is confirmed that P15G1 only supports PCIe/NVMe SSD and SATA SSD
Theofficial data on body
size and weight ofthe body P15G1 are as follows:
The non-touch screen version is 375.4 x 252.3 x 24.5/31.45mm. Weight starts at 2.74kg, and the touch screen version should weigh slightly heavier than the non-touch screen version due to the increased thickness of the touch screen, so the thickness of the entire machine becomes 25.25/32.2mm
The author collected dell, HP, ThinkPad three brands, the same 15-inch performance-class models, in recent years, the size and weight of the representative models, compared to the following chart (Note: The last of these models, HP ZBook 15, has an official web link of:https://support.hp.com/cn-zh/pro ... /document/c03934138, the dimension data marked on the page is obviously incorrect, so the author did not fill in the form, but the screenshot is attached below, for reference only, to mirror.
）
As can be seen from the above comparison table, the ThinkPad P15 is a little less wide (2mm) than the previous generation P53 and the first generation P50, the depth remains the same, but the layout thickness and the weight of the whole machine number, but increased; At the same time, the Size P15 and the size and weight of the previous generation, compared with the Dell and HP peer models, are mostly heavy
In this contrast, the 15-inch, orthodox performance-class mobile workstation P15G1, actually can only be built-in two M.2 2280 PCIe/NVMe SSD, which can be built-in hard drive number, but lower than the size of the smaller weight of the same player Dell Precision 7550 and HP ZBook Fury 15, for which the author can only shake his head
The author has not yet been exposed to dell Precision 7550 and HP ZBook Fury 15, naturally there is no hands-on experience and personally measured data for both. Or put down the tangle of the shaking head above, first dedicated to the P15G1 body experience!
P15G1's fuselage base (CD surface) material for PPS and GF, the author according to the practice of two hands strongly twisted, one-handed palm rest corner movement test, its rigid performance is speechless, completely can not find the shortcomings
THIS P15G1 IS A TOUCH SCREEN VERSION, AND COMPARED TO THE NON-TOUCH VERSION, THE SCREEN HAS MORE GLASS PANELS REQUIRED FOR TOUCH FUNCTION, RESULTING IN A SLIGHT INCREASE IN THICKNESS AND WEIGHT. EVEN SO, IT IS PROTECTED BY THE HIGH EDGE STRINGS ON THE LEFT AND RIGHT SIDES OF ITS SCREEN BORDER
The P15G1's upright screen shaft, hinge tightness compared to the previous review of the ThinkPad P1 Gen 3 slightly tighter, but because the body base weight is much higher than P1G3, so the use of one-handed operation screen open and close, still no problem
The P15G1's on-screen cover, made of GFRP 50% (PPS695 plus 50%) is basically the same as the base, so it's also very rigid, with better twisting and press testing than the pursuit of the lightweight ThinkPad P1 Gen 3, with a lower degree of screen ripple
TO SUM UP, THE AUTHOR OF THE P15G1 BODY MATERIALS AND WORKMANSHIP, IS VERY SATISFIED, COUPLED WITH ITS UPRIGHT SCREEN SHAFT DESIGN, SQUARE AND WITH A TAPERED CONTRACTION OF THE SHAPE, NO FRIVOLOUS THICKNESS AND THE WEIGHT OF SHENDIAN, HOLDING IN HAND, THERE IS A "HEAVY SWORD WITHOUT FRONT" FEELING
Port
P15G1 as a performance-class model, of course, will not be like a "sword" around the smooth, its left and right rear three sides, remove the cooling window and safety keyholes and power sockets, a total of 9 ports and 3 slots The nine ports basically guarantee the user's daily needs, while the configuration of the dual Thunderbolt 3 ports, plus HDMI and USB-C, in theory, the P15G1 can achieve simultaneous external 4-way display, and the native screen to achieve 5 screens with the same display.
If this is the case, the next section will be measured. .
As for the 2 slots, the SIM card slot, the SD card slot, and the SC card slot described above Add in: The content of the previous content is negligent, this P15G1 factory does not have a built-in SC card slot, so its palm rest in the lower right SC card slot is vacant.
The following image shows the JSC1 interface on one side of the red box, which is the SC card line interface, which is vacant on the right side of the motherboard battery interface, and the user can add it on their own if needed
Themost obvious difference between the key rat
P15G1 and the 15-inch ThinkPad P1 Gen 3 is that the C-side of the P15G1 has a numeric keypad. The reason is that its thickness can have a full numeric keyboard, the body on both sides still have enough space to place ports;
For the same reason, the P15G1 keyboard can be disassembled directly from the C side without the hassle of the ThinkPad P1 Gen 3 However, the keyboard is not primarily used for easy disassembly, but for input use.
The P15G1 has more space to decorate the keyboard, except for the convenience of the numeric keypad, how does it compare comfort to the ThinkPad P1 Gen 3?
Due to the time relationship, the author in P15G1 actual use of the keyboard time is not long, only use it to complete the evaluation of the previous text creation input, feel that its key feed and P1G3 seems to be not very different, the key process did not find much difference But compared with the keyboard of thinkPad P71 used by the author for nearly three years, the difference is more obvious
First, the keyboard layout is compressed in landscape size, and below is the removed P15G1 keyboard, placed on the ThinkPad P71 for visual comparison.
From the left red line, you can see that the position of the function key F10 is significantly different, to the right red line, the position of the main keyboard is obviously short And it's not that the P15G1 is 15 inches and the P71 is 17 inches, and that there's a big difference in body width, but that it's the "shrinking" that starts with the P15G1's predecessor, the ThinkPad P52
Previously, the same 15-inch ThinkPad P50/P51 and the 17-inch ThinkPad P70/P71 used keyboards of the same size
Fortunately, under such shrinkage, its keys still retain a good size and spacing, its arrow keys are not too narrow adhere to the four-key layout, otherwise, it is afraid that the ThinkPad classic keyboard layout, causing serious injury again ...
Secondly, the P15G1 key range can obviously feel less than P71, but in terms of comfort, the author does not feel obvious discomfort;
Finally, the author can only be judged according to their own experience and hobbies: if the keyboard score is 100 points, P15G1 is 82 points, ThinkPad P1 Gen 3 is 80 points, DELL Precison 7750 is 70 points, ThinkPad P71 can give 87 points On the dual mouse side, the P15G1's touchpad system eliminates physical keystrokes and replaces them with a chik pan feature.
For this point, the author is indifferent, and did not experience. Because the author daily either use the pointing rod, or use the external mouse. . It can only be said that in terms of appearance, cost, and maintenance, such a design is better than the physical keystrokes
P15G1 pointing rod changes, has been mentioned in the previous article, the most obvious place is that the height of the pointing rod and cross-section value significantly reduced, resulting in the pointing rod cap (commonly known as Little Red Riding Hood) height and installation holes are also significantly smaller Although the outer shape of the pointing rod cap remains the same size, the author is fully convinced that the official change must have been hard work, trying to make the comfort not to drop too much, but the difference in physical scale results in significantly different leverage torque, such a natural rule can not be reversed
Therefore, the author feels that the P15G1's pointing rod operating comfort, obviously not as good as the ThinkPad P71
But if you compare the P15G 1's finger bar with the pointing bar on the DELL Precison 7740 and HP ZBook 17 G5 that the author has been using for many months, then the P15G1 is the king, the 7740 and 17G5, that's the scum!
Finally, the author faced the P15G1 and P71 keyboard, the heart can not persuade themselves:
"You do not resist in the end, you want to be good, you do not stick to the classic, you want to embrace the new happy, you do not pursue comfort, you want to pursue performance ..."
Screen
As a PC, the first classical physical part of human-machine communication, in addition to the input keyboard mouse, is the output screen, but also for comfort and work results play a key role in the components This P15G1 is equipped with the last of the four official optional screens in the following image, the official parameters are:
resolution 3840x2160, support for Dolby Vision HDR 400, brightness under SDR 400 nit, HDR under 500 nit, color gamut is 100% PCI-P3, viewing angle of 170 degrees, not as good as optional 4K
WVA panel 178 degrees;
AS MENTIONED IN THE PREVIOUS ARTICLE, ALTHOUGH IT CLAIMS TO BE "ANTI-GLARE ANTI-FOULING", BUT ITS MIRROR EFFECT IS STILL HIGHER THAN THE ORDINARY SCREEN, ANTI-FOULING EFFECT ALSO SEEMS TO BE UNABLE TO REFLECT, CAN ONLY SAY THAT AFTER THE STAIN, THE USE OF 3M CLOTH WIPE CAN BE EASILY CLEANED
Using AIDA64 to view screen panel information, the official number ISLEN4141, produced by Samsung, manufacturer model ATNA56WR08-0, last year's launch of the ThinkPad P1 Gen 2 has started to choose
The previous article has said that this P15G1 screen, factory has passed the X-rite PANTONE certification calibration, factory pre-installed X-Rite color assistant, can easily call multiple pre-made or customized color configuration, the default boot self-start During the test, the author kept the default configuration file for the X-Rite Color Assistant power-on call without processing, turned off the X-Rite Color Assistant, and then used SpyderXElite for measurements
Using SpyderXElite, the results are as follows:
Color gamut ---- 100% sRGB, 92% Adobe RGB, 100% P3 and 90% NTSC ---- excellent results, measured 100% P3, no difference from the official designation, but 92% of Adobe RGB results slightly regret
the measured curve obtained by the tonal response ---- can basically coincide with the curve of 1.8 degrees of luster and perform well.
gray-order ---- in the 20 to 80, in the range of 6000 to 6450 kelvin, belongs to the good;
exaggerated, The black value (also known as black level) under the four brightness is 0, also does not exclude the measurement instrument used by the author, the OLED screen test is insufficient
good
performance
category
Finally, SpyderXElite gave the highest 5-star rating to the P1G3's screen, color gamut, hue and contrast.
It's 3.5 stars; color uniformity gives 4.5 stars; white dots and color accuracy give 4 stars; and the final overall rating is 4.5 stars As far as the author is concerned, this P15G1 screen can be counted as excellent, especially due to the characteristics of the OLED screen, its contrast value is very impressive
normal. but when the outdoor sun shines directly, its display of available effects quickly drops. .
In addition, as far as the author's daily use is concerned, as a 15-inch heavyweight performance pen, the use of the touch screen scene is really not much, but can produce an additional screen to support the function of 10 touch, better than no;
Functionally all write well, which is great for users who need to use a stylus for content creation!
To sum up, this P15G1 OLED touch screen, its comprehensive quality can meet the needs of most image processing users, and, for users who need a stylus to do the work, it is more in the middle of the bottom. Of course, its screen refresh rate is only 60Hz, which is not an advantage for e-racing users The CPU P15G1's MTM is 20S-US09800, using the Intel WM490 chipset, and the CPU is intel Xeon W-10885M.
The highest performance under the same doorline is theoretically second only to the i9-10980HK, which is also an 8-core 16 thread, and the view of CPUID using AIDA64 shows that its PL1 is 56 seconds 90W and LP2 is 2.4 4ms 135W, although the value shown on the i9-10885H on the thin ThinkPad P1 Gen 3 is the same, but the author feels that its performance is absolutely better, its actual performance is as follows, see below.
The results of the author's test are as follows:
In the Cinebench R15 multi-core performance test, the measured score is 1855 points, in terms of single-core performance score of 219, are higher than all the comparison models, far better than the author recently tested the ThinkPad P1 Gen 3 on the i9-10885H performance
In the Cipribench R20 test, the multicore performance score was 4208 and the single-core performance score was 528
In the comparison of 50 continuous cycle test score curves using Cinebench R15 multicore performance, the same is true of the performance of the W-10885M on the P15G1: the highest score is 1838.24, the lowest score is 1702.56, and the average score is 1745, which is better than other models, although the score curve fluctuates significantly, indicating that its performance fluctuates slightly In the stress test and temperature testing, the author will further study this
The GPU
P15G1 is a dual graphics model that can be run in BIOS as a dual graphics or monochurch mode; Intel CPU integrated UHD graphics cards are not the focus of this review, the focus is on its discrete graphics card, because: its last ThinkPad P53, is the first to be announced with the then most high-end mobile graphics card 15-inch model , the author also bought P53 last year ready to test its performance, but due to more transactions can not be executed, to hand without opening the box on the transfer of this P15G1 equipped with independent graphics card and the previous generation P53 is the same as NVIDIA Quadro RTX 5000 Max-Q, with 256bit 16GB GDDR6 memory:
Its theoretical performance, in the NBC Mobile Graphics Comprehensive Performance Rankings, is below full speed for the Quadro RTX 5000 pen version, located between the RTX 2080 Super Max-Q and rtX 2080 Max-Q.
Testit using 3DMark benchmarking software and get a graphics score comparison as follows:The RTX 5000, second only to the Dell Precision 7750, has a total score of 99.0%, which is only 1% worse than the same THINKPad as the RTX 5000
P73 and Dell Procision 7740 were also only 0.4% higher
In 3DMark's Port Royal benchmark comparison, the P15G3's RTX 5000 Max-Q performed slightly weaker, with a total score of 98.3% for dell Precision 7750 and 93.4% for DELL Precision 7740 That's just 1.5% higher than the thinkPad P73 total score
Testit with VRMark benchmarking software and get the following score comparison:97.3% of Dell Precision 7750, Lenovo Legion Y7000P (configured as Core i7-10750H-RTX).
2060) 123.5%. Some of the P73 and 7740 in the figure score abnormally, for reference only (the author estimates that Nvidia's graphics driver had a problem during last year's test).
Its professional graphics performance is measured as follows:
Using the SPECgpcViewperf 13 benchmark software, the performance of its dual graphics card and the exclusive mode were tested separately, and the results were compared as follows:
The total score in dual graphics mode is higher than the ThinkPad P73 (configured as Xeon E-2276M-P630 plus). Quadro RTX5000) dual graphics mode;
Under the monolith mode, the total score is 101.6% of dell Precision 7740 (configured as i9-9980HK-Quadro RTX5000) and 97.3% of DELL Precision 7750 (configured as i7-10875H-Quadro RTRX5000).
Using the SPECgpcViewperf 2020 benchmark software, the performance of its dual graphics card and the exclusive mode were tested separately, and the results were compared as follows:
The unique mode is divided into 92.6% of dell Precision 7750, which is 126.0% of its own dual display mode
Storage
This P15G1 factory pre-installed two 16GB memory, is SK hynix DDR4-3200, configured to support ECC memory Xoen processor model, actually pre-installed is not supporting ECC memory, the author is a little dissatisfied, and under the current official BIOS, can only run in the 2933MHz state Using the cache and memory benchmark module of AIDA64, the P15G1 was tested in dual graphics mode and unique mode respectively, and the results are as follows: on the left is dual graphics mode, on the right is the exclusive mode, you can see that in both modes, the exclusive mode CPU OC is displayed as 107%, the memory delay is 63.3ns, the dual display mode OC is 99%, but slightly lower is 56.0ns
The author has not used Toshiba's products since changing its name to Man, so I tested them. . Using AS SSD Benchmark and Crystal DiskMark benchmarking software, the 1GB reading and writing test is as follows:
Then use AS SSD Benchmark to test it for 10GB, and the results are as follows, which is good:
Finally, using Crystal DiskMark, it tested 64GiB, and the results were as follows, and the results were good
However, the P15G1 chipset, is Intel WM490/CM256, which supports pcIe channels up to 24, can support up to 8 SATA, support RADI 0/1/5/10, the author is deeply dissatisfied with its P15G1 can only be built-in two M.2 PEIe/VNMe SSD RAID 0/1 As the fourkey elements of PC performance (CPU, GPU, memory, and hard disk) have been measured, let's see what the P15G1 performance test will look like
PcMark 8 was used to test the P15G1's comprehensive performance, and the results were compared with the following graph:
The total score in the exclusive mode is 114.4% of the total score in dual display mode, which is higher than the total score of all other contrasting models;
On the sub-score, only Work scores slightly lower than Lenovo Legion Y7000P (configured as Core i7-10750H-RTX 2060), which is excellent!
Using PCMark 10 to test the P1G3's overall performance, the results are compared to the following graph:
Total score in dual display mode, 110.5% of total score in dual display mode, total score and all sub-scores are higher than all other comparison models (Note: some models do not have PCMark 10 Applications sub-project score), the performance is also very good!
Using the UserBenchmark benchmarking software, the performance of its dual graphics card and exclusive mode is tested, and the results are as follows:
Under unique mode, UserBenchmark rates Gaming (game performance), Desktop (desktop performance), and Workstion (workstation performance) with p15G1 ratings of more than 100% and UFOs
Tested using SPECwpc 2.1, a professional graphics comprehensive performance benchmarking software, the results and comparisons are as follows:
The total score in P15G1 dual-display mode is not much different from the Dell Precision 7750, with a total score of about 7% higher than Dell Precision
7740 about 3%.
Tested using the professional graphics composite performance benchmarking software SPECworkstation 3.04, the results and comparisons are as follows:
The total score is higher than dell Precision 7750 and DELL Precision, both in dual-display mode and in exclusive mode
7740 points. .
