PUBG, Project Cars 2, Quake Champions, Shadow of War, Sniper Elite 4
Like Far Cry Primal, PUBG is another title that's always run noticeably worse on AMD hardware. The margins aren't horrible but they're not good either. Last time I benchmarked this title just after it left early access the Ryzen 5 1600X was 17% slower than the Core i5-8400.
This time the 2600 was 14% slower than the 8400 so it seems little has changed. Overclocked the 2600 didn't make up much ground either and even at 1440p Intel retained the lead. Of course the game was still very playable on the Ryzen 5 2600, you can just expect better results with the Core i5-8400.
Okay so stock out of the box the Ryzen 5 2600 is limiting performance of the GTX 1080 Ti at all three resolutions. However once overclocked the GTX 1080 Ti is limiting the performance of the 2600 and the same is also true for the 8400. Although the stock 2600 is limiting performance at 1440p, it's very minor and overall performance is much the same for all three configurations at this resolution.
Quake Champions is another example where the Core i5-8400 provides strong performance right out of the gate, of course you can't overclock this part but the evidence would suggest that for the most part you don't need to. The stock 2600 struggles at 720p and 1080p in relation to the Core i5, I'm not saying the frame rates aren't high and I'm certainly not saying it wasn't playable but I am saying in relation to the 8400 it was slower, but to 18% slower in fact.
In order to match the Intel processor the Ryzen 5 2600 needs to be overclocked and this allows it to extract maximum performance from the GTX 1080 Ti. Of course once we get to 1440p all three configurations are able to max out the GTX 1080 Ti and it's here that overclocking becomes pointless anyway.
Next up we have Shadow of War and this title is primary GPU bound, this was certainly the case at 1080p and 1440p. The Core i5-8400 does edge ahead of the 2600 at 720p but once we overclock the 2600 it clearly takes the lead.
Sniper Elite 4 was tested using DirectX 12 and here the Core i5-8400 was much faster than the stock 2600 at 720p and 1080p. Interestingly once we hit 1440p the stock 2600 pulls ahead, I'd say this is down to the fact that we've usd a GeForce graphics card and tested with the DX12 API. Anyway regardless of resolution once we overclocked the Ryzen 5 2600 it is clearly the faster CPU and provided much greater frame time performance at 1080p and 1440p.
