This refresh is DOA because of using old Maxwell GPUs. I can't understand why they would do that.

This refresh is DOA because of using old Maxwell GPUs. I can't understand why they would do that.

Other 15" workstation-class laptops also have maxwell GPUs (Precision 7520, Zbook 15 G4) only 17" models offer Pascal (P71, Precision 7720, Zbook 17 G4). The reason for this may be the much higher TDP of the corresponding Pascal cards. (P3000, is 75W, whereas M2200 is 45W)

@Zorro:

Maybe, but then again, TDP could be another alibi.

Dell, HP and Lenovo possibly don't have the skills to put together stable and lightweight 15 and 17" laptops, that can handle GTX1070/1080 equivalent performance. They're not major gaming brands after all.

Nevertheless if they can, they're likely anxious about the pricing for large corporations that bulk buy, which they know are already too overpriced. An additional batch of custom cooling solutions would jack up those numbers sky high. Average consumers would of course applaud a nice dGPU in a durable chassis, but businesses could disapprove, so the profit could take a hit.

Any info on the Full HD display? Is it improved over the P50 and how much more battery life could I gain if I choose that one instead of the 4k? I don't care about resolution, but I do care about color accuracy and battery life.

Hi,

  What is the brand of the screen 4K?

Best regards,

@Filip:
Unfortunately, same as before: jaw-dropping 250 nits of brightness, 700:1 contrast ratio, 60% sRGB / 35% AdobeRGB color gamut, and 160 degrees viewing angle. Battery life browsing (no video playback) is around 8 hours with the FHD and 6 hours with UHD, with increased brightness eating more battery on a higher resolution display.

@zobix:
P50's UHD panels solely made by Sharp. With the P51, there's a lottery between BOE (Beijing BOE Technologies) and AUO (AU Optronics). You probably already know this but quality wise, AUO>LGD>BOE.

The FullHD Lottery is really crap. At the moment i have the AUO FullHD Display in my P51. Because of a dark area it will be replaced. The AUO is sad in Colors and in Brightness. Black level is good. The new one will be a LG Display. I hope to get better Colors and more Brighness. On the P51 nonTouch FullHD there are only 2 Display. The AUO and the LG. I will report wether the LG is better or not.

How come this isn't on your Top 10 list for workstations? A common problem with NotebookCheck unfortunately. But in most other regards this site and its reviews are great!

Is it better than Zbook 15 G4, bit with the most powerful Xeon?

@skan:
No they're almost identical, performance and specs-wise. But the P51 is cheaper than the HP's ZBook 15 G4 and much cheaper than Dell's Precision 7520.

Any idea if LG FHD is using PWM? i used it for an hour and it strained my eyes quite a bit. Thank you.

It seems the battery for Thinkpad P50 and P51 has two voltage 11.25V/8000mAh  and 15V /4400mAh but they have same battery type No.00NY491 SB10H45076 (http://www.battery-store.eu/laptopcomputer/1004285.htm)

MSI and Clevo has managed to put Quadro P3000 and P4000 into light and thin 2 kg 15" laptops (WS63VR , P955HQ1/3) based on their slim gaming counterparts (GS6xVR , P95xHP6/HR). Thinkpad should have a competitor as well but with a large battery, thin bezels and a second M.2-2280 slot instead of a 2.5" all like Gigabyte Aero 15W/X but with a centered keyboard w/o the numpad.

Just a thought.

This is a very nice review however i would like to correct on one topic - P51s has nothing to do with P51. in the past, we used T560 - P50s as differece between GPU config. P50s was orderable with Nvidia while T560 was not. This is no longer the case with T570 - however we decided to continue with P51s line. But the motherboard is same. So it is better to compare those two. P51 is a replacement for W (orkstation) line, therefore comparison between 50(1) -70(1) would be more accurate. Our newest P52 will be even more powerful, as this will be our first 8th Gen ( not-refresh ) CPU with new Pascal GPU as well.

It seems that the GPU in the test unit (Quadro M2200) and the one that was delivered are somewhat different.

According to GPU-Z:

Test unit (info from the article):
GPU: 1436
ROPs/TMUs: 32/85
Texture Fillrate: 59.1 GTexel/s

My Quadro M2200:
GPU: GM206
ROPs/TMUs: 32/64
Texture Fillrate: 44.5 GTexel/s

Also Techpowerup site confirms that M2200 has 32/64 ROPs/TMUs.
After doing a bit benchmarking I found out that:

* I get consistently lower (~8%) benchmark scores for 3DMark06 and 3DMark 11 Performance.
* Cloud Gate score is ~21% lower.
* Fire Strike seems to be lagging 1-2%.
* Time Spy score seems consistent with the review.

tl;dr - screen is broken, need replacement

Hi - this might be a long shot, but does anyone know how I can get a 4K Xeon Screen replacement?
Or if it would be okay to put a lower resolution screen on this machine in its stead, maybe?
