Bonus: Clock for Clock 2nd vs 1st-Gen Performance
Long Run Stress Test
While on the subject of coolers, as we've said, all stock 2700X testing was done with the Wraith Prism box cooler and all overclocking was conducted using the Corsair H150i Pro. Running our Blender stress test the 2700X held a clock speed of 3.8GHz on all cores, upgrading to the H150i Pro increased that frequency to 3.9GHz and this improved the render time by less than a single percent.
So not a big deal but it does suggest that those overclocking will want to upgrade the cooler and we’ll explore options in a future article.
Before wrapping up the testing there were a few more benchmarks I wanted to squeeze in. These next few graphs compare the Ryzen 7 2700X and 1800X clock for clock at 4GHz on the same X470 motherboard using the same memory and timings. Interestingly, while we haven't been able to get the 1800X working with memory higher than DDR4-3200 on our X370 boards, it worked all the way up to DDR4-3600 on the X470 boards. I'll have to look into this more in the coming weeks but this is very interesting indeed.
Firing up Cinebench R15 we see that the memory frequency has little impact on this test. That said, we do see that AMD's claim of an approximate 3% increase due to IPC gains is spot on, at the same frequency the 2700X was up to 3% faster, though for the most part we saw gains of 2%. Still better than nothing, I say as I gaze over to my Coffee Lake CPU, and Kaby Lake CPU, and Skylake CPU...
Interestingly, the difference between G.Skill’s Sniper X DDR4-3400 CL16 and DDR4-3600 CL19 memory is virtually non-existent. The looser timings of the higher clocked memory nullify any advantage the higher frequency might bring.
Although we only saw a 2-3% improvement with Cinebench R15 here we see the 2700X shaving 7% off the render time. Of course the improved cache performance could also be helping here but it's great to see the second-gen Ryzen CPU offering such a noteworthy improvement when matched clock for clock.
Finally, we have Battlefield 1 and you can see that AMD has made great strides here. The 2700X was 5-6% faster when comparing the 1% low data and 7% faster on average. Granted, those are single digit gains but that's really going to help Ryzen do battle with the Coffee Lake CPUs in the gaming benchmarks, as we’ve already seen.
Remember, we're testing with a GTX 1080 Ti at 1080p using medium quality settings, Ryzen now has a much better chance of finding the limits of your graphics card under more realistic gaming conditions.
