Unclear performance differences with similar hardware

from AshesoftheSingularity Forums

Hi

1. I have two laptops with around the same hardware - the MSI GT62VR 6RD and Clevo P650RP6, both have the same basic hardware and software:

- I7-6700HQ, GTX 1060 6GB, 2x8GB 2400MHZ, 128GB SATA SSD

- Windows 10 64-bit, same version 1511, Nvidia 372.70 drivers. GPU only, G-Sync disabled

 

2. The GT62VR 6RD get a lot higher FPSs in the built-in benchmark, all settings, at 900p, 1080p and 2160p. Big differences. Extreme settings, DX12@1080p 48vs40 FPS, High 58 vs 48, Crazy 35 vs 32

 

3. I've recorded stats with HWInfo and it seems like the GT62VR has somewhat higher GPU clocks of around ~3% while running the benchmarks, but that can't be the difference. CPU maintains around 3.1GHZ in both laptops.

 

What can it be? it looks very strange..

I assume both laptops are plugged in and High Performance is chosen on both. 

I would monitor CPU and GPU temps, one might be throttling compared to the other. The higher the graphics setting the closer they come in performance which suggests to me it could be the CPU throttling. The higher the settings, with the accompanying lower frame rate, then the CPU has to work less hard and the GPUs work harder.  The lower the settings then the CPU has to work harder and that is where you are seeing the greater difference. Just a theory.

Adding to what Ticktoc said, if one has more "stuff" on its drive, it'll be slower. Same goes for if one has viruses. Or if one has a buttload of stuff cached compared to the other. Then of course, clocks and cooling will make a ton of difference. Before I bought my second R9 280X, I had a crazy high clock on my one card, but it would eventually throttle down, meaning the game would start with north of 60FPS, and eventually fall to the 20s before I'd give up and play something else.

Thanks for the reply

 

1. Yes, both plugged

2. Except difference of 50MHZ on average for the GPU clock whiile running the AoS benchmark, I didn't see no throttling. Thermals are very good

3. In other games, including Total War : Warhammer, Hitman, Rise Of the Tomb raider and Ark, they are more or less the same

4. Maybe I could provide any information that could shed some information about it?

 

It almost seems to me that one of the laptops still runs the 1.31 version with lower FPSs..

I've tested with my external HDD where my steam stuff is - same for both laptops

The difference is really big... looks like some kind of difference in the software
