Intel Core i7-8700Ok, i5-8600Ok, 8400 versus AMD Ryzen 7 1800X, R5 1600X, 1500X

You read the reviews, we highlighted their pros and cons, and now we're putting them together in a single CPU comparison. On deck we tested 8 processors in 9 games with not only 1080p, but also 720p and 1440p, which corresponds to more than 650 benchmark passes. The goal? To see how Intel's eighth generation core series can assert itself against earlier parts of the seventh generation and against Ryzen.

In order to avoid performance problems with DirectX 12 titles, we used the Vega 64 Liquid Cooled graphics card for testing. The 720p results should help eliminate GPU bottlenecks. I could go back and test with a GTX 1080 Ti if we think this is necessary.

Please note that none of the CPUs has been overclocked. However, we plan to run an overclocked version of this test soon. As always, the Intel core CPUs had the turbo core functions disabled and all chips were tested with DDR4-3200 CL14 memory.

Most of the games were tested with the second highest quality preset – in fact, Battlefield 1 was the only game I maxed out. That covers almost everything … let's jump to the results.

Benchmark time

Battlefield 1 comes first with 720p, and here we see that even at this low resolution, all three eighth-generation core processors deliver almost the same result. The Core i5-8400 corresponded to the minimum frame rate of the 8700K and was only 2.5% slower on average.

This meant that even the 8400 was a step ahead of the 7700K, while the 7600K looked a little overwhelmed. Here we see quite a mismatch between the minimum and average frame rates of the 7600K.

Despite an average of 151 fps, the 7600K offered a significantly worse experience than the Ryzen 5 1500X. Speaking of Ryzen CPUs, they look a bit good down here. The Ryzen 5 1600X was 22% slower than the Core i5-8400 when you compare the minimum frame rate, which is quite a deficit.

Jumping to 1080p leads to a more severe GPU bottleneck, and while the performance of the Vega 64 graphics card is still impressive, it limits us to around 130-140 fps. Here we hardly see a difference between the core CPUs of the seventh and eighth generation, while the Ryzen CPUs are still lagging behind, although this time the margins are greatly reduced due to the GPU bottleneck.

At 1440p we see almost the same thing, although the Ryzen CPUs are still a bit slower and the R5 1500X finally catches up with the R5 1600.
