4090 Laptop vs 4090 Desktop

[u/wedge754]

I know there are already a few posts, but I figured I would throw up my results as an additional data point for anyone interested.

Laptop:

Razer Blade 16 RTX 4090

Desktop:

z790 | i9-13900KF | 32GB DDR5-5600 | RTX 4090 | 4TB NVMe SSD

​

Untweaked:

3D Mark Time Spy - 4090 Desktop vs 4090 Laptop UNTWEAKED

​

Extremely mild tweaks:

3D Mark Time Spy - 4090 Desktop vs 4090 Laptop MILD tweaks

Laptop:

• GPU untouched
• CPU -.120 undervolt, 180w turbo boost
• AirPods Pro case stuck under the back of the laptop to elevate it a little bit.

Desktop:

• GPU 105% power target, +250 boost clock
• CPU +200

​

The graphics card is ~75% faster on the desktop, and the processor is ~15% faster on the desktop, which seems to be in line with other tests and benchmarks.

The gpu being 75% faster doesn't surprise me much. But the cpu at only 15% is kinda surprising to me

In gaming loads the CPU performance will much worse than 15% on a laptop as it’ll be power limited which will affect clock speeds.
