Hey SC Reddit,
Recently I upgraded to a 9800x3d from a 5800x, and I thought I'd post my performance gains for anyone who plays a lot of StarCraft 2 and is considering making the jump themselves.
Attached are two replays I used to benchmark the performance of the chip, specifically with relation to StarCraft. Obviously the 9800x3d just bench marks higher, but every game performs a little bit differently. As most of you probably know, SC2's performance is directly tied to CPU performance, and is 100% bottlenecked by it if you have even a remotely recent GPU.
When you pause a replay you're obviously able to directly match up the frame rates, but the frame rates are substantially lower the moment you hit play. It's important to hit play, because the x3d v-cache actually helps with sc2 so much, that when there's a lot of action going on the amount of better it is than the 5800x, goes up. I think it's something like 1.8x better when there's no action, and over 2x better when there's battles going on. These tests were done at all low settings, medium shaders, ultra textures.

Summary:
Honestly anything with v-cache is going to be insane. So if you have a gen 1 or gen 2 ryzen, I recommend seeing if you can get a 5600x3d, 5700x3d, or 5800x3d (Not all boards support it but I think anything over x370 does for sure, maybe x270).
As just a bit of tech nerding out, the 9800x3d is actually insane. It's the first ryzen cpu I've seen that allcore boosts to the same clocks it single core boosts at. This is pretty massive, because the single core for the 5800x was way higher than all core, and even running chrome in the background could cause a loss of like 15% performance in SC2. Now the cores with SC2 are always at 5.2ghz, no matter what is going on in the background. Did I mention the -40mv offset, which makes it run 30w more efficiently and drops it 20 degrees for free? No?
I have not seen this thing dip below 240 fps ever, for any reason. So if you have a 240hz monitor, this is the one.
Man this thing fucks.
