AMD 3D vcache vs clock speed for main thread performance?

[Roosterfeet]

I recently upgraded my GPU and I've been noticing stutters in CPU intensive missions like those generated by Liberation. I will briefly become main thread limited and there will be a short dip in frame rate. The x3D processors have overall better gaming performance vs their non 3D vcache counterparts but I'm wondering if I wouldn't be better off with a higher clock speed instead for the DCS main thread bottleneck that I'm seeing.

For primarily gaming and in your case (3600), I would go for the 5800X3D for a drop-in cost-effective upgrade.   For AMD, more than 8 cores can involve a CCX to CCX latency complication.   The 5800X boost clock is 4.7Ghz and 5800X3D is 4.5 Ghz, so +4% is not that significant.   If you have a stock cooler, you may need to upgrade that for anything above a 65W TDP (ie 5600X).   By the way, the 5800X runs fairly hot but the 53800X3D responds very well to under-volting to keep all core load temperatures reduced.

Good point about the actual difference in clock speeds. I am running a stock cooler on a 65W processor at the moment. Any recommendations on what kind of cooler I would need for a 5800X3D? I do no significant overclocking. I run everything at default bios setting except for loading the xmp profile that came with my ram.

Check the Thermalright Peerless Assassin 120 (regular or SE variant), it goes for just 40 bucks/euros.
