You may see slightly better performance using faster memory, but you'll be unlikely to get that working on 1st Gen Ryzen CPUs.PCMark 10 Image editing BenchmarkI’m a technology journalist with a 25 year-long interest in computer hardware, gadgets and technology. Nevertheless, the Core i9-9900K is still around 1.09% faster here, according to the leaked numbers.The Core i9-9900K surpasses the Ryzen 7 3800X when it's combined with DDR4-2666 memory, Intel's official supported memory speed. AMD Ryzen 7 vs. Intel Core i7: CPU Face-Off in Microsoft's Surface Laptop 3. If you've set your heart on the Ryzen 7 3800X, though, and want to know whether to buy it or Intel's two 8-core CPUs, it isn't quite as clear cut. As you'll see in various other benchmarks, the overclocked result for the Ryzen 7 3800X is lower than the stock speed result, for the simple reason the frequency is lower than the peak stock boost speed.Cinebench multi-threaded benchmark The Intel CPUs both have a lead here, with the AMD 8 and 12 core CPUs bunched together at around 105fps 95th percentile minim frame rate and 129fps average frame rate, with all three within the margin of error, which can be a few frames per second in this game, but it's fairly clear that Intel's 8-core CPUs have big leads with a relatively powerful graphics card and the most popular gaming resolution - 1080p, which does lean more on the CPU.Intel might claim that Cinebench is maybe not an entirely relevant test given its small userbase, but the fact remains that you'll see similar results in other multi-threaded tests too such as HandBrake, where once again the Core i9-9900K was matched by the Ryzen 7 3800X.PC Mark 10's image editing test seems to love AMD CPUs with even the Ryzen 7 2700X offering similar results to the Core i9-9900K with the Ryzen 7 3800X way out in front.A third place result in Cinebench's single-threaded test is excellent for AMD, although once overclocked, the Core i7-9700K was quicker thanks to a massive 5.1GHz frequency, but if you're not overclocking the AMD CPU is once again a match for Intel's more expensive flagship.The multi-threaded test sees a similar result - the Ryzen 7 3800X sitting level with the Core i9-9900K and a huge amount faster than the similarly-priced Core i7-9700K and also offering a massive boost over the Rzyen 7 2700X too.I've rebuilt my test systems so they use cutting-edge components and also fully up to date versions of Windows 10 with the May 1903 update along with all the various security patches - both from motherboard manufacturers and Microsoft as these are known to have impacted on performance making any data obtained prior to these updates incomparable and unrepresentative.Cinebench single-thread BenchmarkShadow of the Tomb Raider benchmarkDespite offering significantly more performance than the Core i7-9700K in multi-threaded tasks the Ryzen 7 3800X system drew similar amounts of power from the wall and once overclocked offered massive power savings while matching or bettering the Core i9-9900K in content creation tests. Shadow of the Tomb Raider and Dota 2, though, both preferred Intel, but the differences here were usually less than those between the two companies in content creation, and will be even less at higher resolutions. The Core i9-9900K performs roughly 14.48% and 0.56% faster in the single-core and multi-core tests, respectively. We'll have to wait for our in-depth review of the Ryzen 7 3800X to properly judge its performance. PC Mark 10's image editing test seems to love AMD CPUs with even the Ryzen 7 2700X offering similar results to the Core i9-9900K with the Ryzen 7 3800X way out in … The Ryzen 7 3800X beats the Core i9-9900K by up to 4.95% in multi-core workloads.Thank you for signing up to Tom's Hardware. For starters, we don't know under what conditions the tests were performed, or if this is Engineering Sample (ES) silicon.
