QuotePriced at around €2,800, our review unit of the ThinkPad P16v Gen 3 is not a bargain by any means, and the RTX PRO 2000 obviously plays a role as well. However, if you look at the performance of the GPU, you might be surprised that Lenovo only implements the 60W version of the RTX PRO 2000, even though the TGP limit is 115 Watts. During our review, we compared the performance figures of the RTX PRO 2000 with the 115W version of the consumer GPU GeForce RTX 5060 (same specs) and the raw GPU performance is around 30 % higher. This means you pay the full price for the RTX PRO 2000, but you do not get the full performance.
FPS/Watt (from the "3DMark Performance rating - Percent" section)
P16v G3 (5060 Laptop at 60W): 76.4pt/60 Watt = 1.2733
5060 Laptop at 115W: 100 pt/115 Watt = 0.8696
It may be a bad take, but this makes the P16v G3 46% more energy efficient, if I'm not mistaken. The highest energy efficiency is usually somewhere around normal TDP/2 (and then it drops off again). 115W/2 is basically what this laptop is set to, positively interestingly.
QuoteThe gaming laptop Lenovo Legion 7 16, which combines a much faster processor with the 115W version of the GeForce RTX 5060 can handle up to 145 Watts, so almost twice the value of the much more expensive ThinkPad P16v Gen 3.
I wanted to say that it's also heavier, but no, the Legion 7 16 is even lighter.
QuoteWe do not want to hide the fact that the Legion is also much noisier under load
I guess this is the disadvantage then.
Another advantage might be the reliability: The higher the temps, the worse. The P16v G3 is expected to last longer than the mentioned faster Legion 7 16, right?, as it also has the lower temps:
QuoteThis is not particularly high considering the large casing.
Tho 80°C on the Legion isn't that bad, but kinda the highest I personally would want it to be.
