Incredible Value.
Then there were games where the 3900X was slower by a 10% margin or greater, seven titles in total where Ryzen was up to 16% slower.Now with both CPUs overclocked we see very little change. One thing for certain is that the Ryzen 9 3900X will perform better than the Ryzen 7 3800X, but the question is by how much it performs better during gaming, and whether opting for the Ryzen 9 3900X is worth the extra cost. AMD says that Auto OC is designed to improve performance in single-threaded workloads, while PBO boosts heavily-threaded applications. Both processors delivered similar average frame rates, yet the 1% low figure was 13% higher with the Ryzen processor. Here the 3900X was 9% slower out of the box and 10% once both CPUs were overclocked. But lo and behold the 3900X was a smidgen faster, performance was basically the same overall, but we didn’t expect the 3900X to push average frame rates higher than the 9900K.We tested the latest version of World War Z which brings about a number of fixes and performance improvements. In terms of frame rates, for very low FPS (certainly not the case at 1080p with a 2080 Ti), 30 to 32 fps is a 7% increase, for example. That’s particularly true given the strong 1% low performance of the Ryzen processor.The Resident Evil 2 results are interesting: stock the 3900X was 6% slower on average, but provided stronger 1% low performance, beating the 9900K by 4%. Looking at currently available benchmarks between the 3800X and 3900X. Thank you for signing up to Tom's Hardware. Performance was perfectly acceptable but for maximum performance the 9900K does deliver the best results.Next up we have Assassin’s Creed Odyssey and this is another title where Intel is a little faster on average but you’ll never notice the ~4% reduction in average frame rates when using the 3900X. 3. There's a few titles that do play noticeably better with the Intel CPU, in StarCraft's case in complex late game 4v4 battles. Where the 3900X did surprise was in Monster Hunter World. Please refresh the page and try again.Motherboard vendors define the power limits for their boards and are developing custom profiles that support a new Auto OC feature. AMD also exposes some of these monitoring features with its Ryzen Master overclocking software.Due to time constraints, we tested the Ryzen 9 3900X and Ryzen 7 3700X with both automated overclocking features activated instead of with a manual all-core overclock. Several motherboard vendors have told us that overclocking headroom is extremely limited on the Ryzen 3000 processors, and that exceeding the boost clocks, or even meeting them, isn't possible for all-core overclocking.
Great value; The Ryzen 9 3900X is compatible with the new PCIe 4.0 enabled X570 motherboard via an AM4 Both stock and overclocked the 9900K was ~2% faster than the 3900X which is a negligible difference. Pros. Then at extreme high frame rates, a 5% increase is going from 200 to 210 fps, which is not a margin worth getting too excited over.The third and final battle royale game we tested is PlayerUnknown’s Battlegrounds. The Ryzen 5 3600 remains king of value bar none, and the 3900X offers more cores for productivity, gaming may not benefit as we observed in our GPU scaling benchmark. We tested with multiple motherboards and met with the same result, which could boil down to the quality of our sample or motherboard firmwares. If you're a content creator who hasn't already dabbled with AMD's killer Zen 2 Ryzen CPUs, the Ryzen 3900XT, a tune-up of the 12-core 3900X, is worth a second glance in its price lane. Although we see a minor 5% deficit for the average frame rate, the Ryzen processor was up to 13% slower when looking at the 1% low performance.
