6 Cores vs. 8 Cores for Gaming: 24 Game Benchmark - TechSpot
Jun 24, 2022 2 mins, 23 secs

For this one we've got a 24 game benchmark covering the 1080p and 1440p resolutions using both the Radeon RX 6950 XT and 6600 XT, with SAM enabled.

Starting with Fortnite using competitive quality settings, we find that the 5700X offers a slight performance advantage, though I wouldn't be too quick to chalk that one up to the fact that we're comparing 6 vs.

We're talking about a small 4% to 5% performance difference and the 5700X typically clocks 5% higher than the 5600, so we'd say this is where the bulk of the performance discrepancy comes from, which makes sense given Fortnite isn't a heavy core user.

Using the 6950 XT at 1080p, CPU usage of the Ryzen 5 5600 never dipped below 80% in our test, generally hovering around 90 - 95%.

At 1080p using the 6950 XT we did find that 1% lows were 10% stronger with the 5700X and that margin goes beyond the 5% clock speed advantage.

The 5600 and 5700X are the primary system bottleneck in this test with the 6600 XT and 6950 XT delivering the same level of performance.

Rainbow Six Extraction is another competitive shooter but this one is entirely GPU bound using the 5600 or 5700X, even with the high-end Radeon 6950 XT.

The Ryzen 5600 and 5700X were neck and neck with the RX 6600 XT, and then with the 6950 XT we see up to a 6% margin favoring the 5700X.

Forza Horizon 5 is kind of lightweight on the CPU, so these results are as expected, basically the same level of performance is seen using either CPU, and with the Radeon RX 6600 XT the game is entirely GPU limited.

The game starts to become ever so slightly CPU limited with the 6950 XT at 1080p, but we're still talking about a 5% advantage for the 5700X.

The 5700X was up to 21% faster than the 5600, seen when looking at 1% lows with the 6950 XT at 1080p, though we saw a milder 10% uplift for the average frame rate.

We're using slightly dialed-down quality settings, but even so we're limited to ~100 fps at 1080p with the 6950 XT using either CPU?

The 5700X was 10-11% faster when CPU bound in our testing, so those extra cores are helping to slightly improve performance beyond the 5% increase in frequency.

For those running high-end GPUs such as the Radeon RX 6950 XT at low resolutions like 1080p, we're looking at no more than a 5% performance advantage for the Ryzen 7 5700X over the Ryzen 5 5600, so overall it mostly came down to the difference in clock frequency.

Then of course, if you're using a slower, mid-range GPU like the Radeon RX 6600 XT, for the most part there's going to be no performance difference to speak of...

Looking at the Radeon 6950 XT's margins at 1080p, the Ryzen 5700X was up to 25% faster, seen in Call of Duty Vanguard which is an outlier in our testing, with a typical margin of just 5%.

For the most part, there's very little difference between the Ryzen 5 5600 and Ryzen 7 5700X for PC gamers.
