CPU Scaling

CPU Scaling

If you are wondering, what would be the effect of a four core versus an eight core processor on the game? We'll lets test just that.

Above we have the Radeon RX Vega 64, the effect of 4c/8t versus 8c/16t CPU cores is starting to matter. F1 2017 likes threads, at 1080p that is a boost of 9% and at WQHD that is 3%. At WQHD the title is more GPU bound at Ultra high quality settings, meaning the effect of more threaded logical (or faster) CPU cores has much less of an effect. 

AMD Ryzen 7 @ 4 GHz versus Intel Core i7 @ 4 GHz

So for our next test I will be performing a 1:1 platform comparison in-between a Ryzen 7 (8-core) processor clocked at 4000 MHz on all cores. Then for Intel we do the same with the 5960X at 4000 MHz on all cores, here we'll simply look at platform performance difference based upon the same graphics card. Both systems have identical software and drivers installed.

So as you can see I clocked both platforms at 4.0 GHz to equalize and neutralize the proc clock frequency turbo differences, this is an all-core tweak for both systems. Both are 8-core part with 16 threads enabled. The AMD system uses the latest AGESA 1006 BIOS and has dual-channel 3200 MHz enabled. The Intel platform uses slightly slower 2400 MHz DIMMs, however that one has the advantage of quad-channel memory.

What about Threadripper?

Well, heck sure we can do that!

So above the default clocked Ryzen 7 1800X versus a default clocked Threadripper 1950X. You can see slightly improved game perf at 1920x1080, marginal to random differences really. I also was tweaking the Threadripper platform towards 4.0 GHz on all cores:
 

So overclocking increase the 1080p FPS to 127, a marginal improvement (but FPS is already good at defaults of course). And now let's compare it all:

And there you have it, a Ryzen 7 1800X, Threadripper 1950X and Core i7 5960X proc all clocked at 4 GHz per core on all cores. The differences are close to NIL.
