CPU impact on a Vega 64

venomtail · November 13, 2023

Slowly piecing together my second PC that I merely want to be a status piece and a PC I can play on when I go on holidays to the cabin. Focus is mainly offline games that I haven't played through, like Nier Tomata, Mad Max, Mirrors Edge Catalyst, Deus EX and what not, your 2010's decade games, nothing 2020 or newer.

Whilst I've yet to try out the used X570 motherboard I've bought, I have my old 2700X I was hoping to use and trying to keep costs down I'd rather use the 2700X than get a used 5600 (I will have to buy one regardless if BIOS is not up to date from previous owner) and squeeze as much performance as I can from my Vega 64. Build is here.

Basically, at what point is Vega 64 powerfull enough to start needing the CPU to pull its weight? Reference would be those mid 2010 games, nr 1 would be aiming at Witcher 3 high/max/ 60fps at 1440p. I really hope this is all gonna be a GPU bottleneck cause I'm still taken aback by how bad the 2700X is actually for games.

VEGA 64 should be fine with a 2700X.
I had my GTX 1080 (which is about the same level of performance as V.64) with a Ryzen 5 2600 (so same generation, IPC and gaming performance as the 2700X), then a Ryzen 5 3600. Virtually the same performance. I was totally GPU bound at 1440p.
And Radeon tend to do better with weaker CPUs. So it's even more unlikely you'd be CPU bound with your V.64.

Good to hear.

What a weird build this one is, as Vega 64 takes center stage, whilst trying to get system to be somewhat playable, efficient and look pretty as well and not spend too much which is why I'm sticking with my 2700X. Not like it has any value in the used market anymore and at least knowing it's been my CPU since day one, I know the care its received.
