I’m buying a new laptop, and i need to compare some based on gpu. I heard a lot of the mainstream ones are biased, but i also need the big databases that the big ones provide, as im comparing some quite obscure gpus. thanks

When you’re buying a laptop you can’t just look at the raw specs. The whole rest of the laptop plays a huge role in performance. Cooling and artificial power limits play a much bigger role in those devices than a desktop.
I have a ThinkPad P1 Gen. 6 with an i9 and rtx 4090 laptop. Should be killer right? This thing gets trounced by i7 4080 gamer laptops. Why? Because the CPU is limited to 35 watts when the GPU is active, and the GPU is limited to 85 watts. Meanwhile the gamer laptops will let the CPU run at 100+ watts and 150 watts on the GPU.
I’d just use the massive sites like TPU to get a vague idea of how things stack. Then look for actual reviews for the laptop you want.
Okay, thanks. im looking at a Lenovo ThinkPad P15v Gen3, with a 135w charger and the cpu itself is only up to 45w, so i think it should be fine?
(edit: even though im looking for some preformance, i also have some hefty price restrictions, so none of the high-end ones come into play)
45 watts is only the “base power” of the CPU. Which in Intel land is meaningless. Max turbo is 95-115w on the CPUs in that machine. PSREF sadly doesn’t list the power it throttles to when the dGPU is active, only the latest few gens of machines do.
Buuut 12th Gen. is when Intel introduced the minimum assured power and even the i5 option is 35 watts. With the much weaker GPU options for that machine I doubt the CPU will be the bottleneck like my machine. But based on what I’ve seen it seems like the system struggles to even maintain the 35 watt tdp when the GPU is active.
It looks like the AMD version is much better. It sticks to the 45 watts for the CPU and 35 watts for the GPU. But used AMD ThinkPads are pretty rare so I’m assuming you’re looking at the intel version.
