Ryzen 9 3950X vs. Core i9-9900KS Gaming, Feat. Tuned DDR4 Memory Performance
Today we're comparing the Ryzen 9 3950X and Core i9-9900KS in a massive number of games, using one of G.Skill's most premium 16GB memory kits, the Trident Z Neo DDR4-3600 CL14. For those of you spending $600 or $750 on a CPU, purchasing best in class DDR4 memory doesn't seem like a stretch, but the main reason we went with this memory was so we could bring you a head to head comparison between AMD and Intel processors using manually tuned timings.
It was discovered in the early days of AMD's Zen architecture that memory bandwidth and latency were crucial for maximizing performance of Ryzen processors. Manually tuning up the secondary and tertiary timings can consistently improve Ryzen's performance in games.
In other words, this is a comparison of Intel and AMD's top desktop CPUs that do not belong to their HEDT series, with both processors tweaked for maximum memory performance.
For this Ryzen 9 3950X vs. Core i9-9900KS comparison we have tested a total of 18 games at 1080p using a GeForce RTX 2080 Ti. Both CPUs were tested in their stock out of the box configuration with XMP for the Trident Z Neo DDR4-3600 CL14 memory loaded. Then we have added a second configuration which sees the G.Skill memory timings manually tuned. The Core i9 was installed on a Gigabyte Z390 Aorus Ultra and, while Ryzen 9 used the Gigabyte X570 Aorus Master.
Before we jump into the gaming benchmarks, here's a quick look at memory bandwidth. As you can see the tuned timings only boost bandwidth by 4% for the 3950X and 3% for the 9900KS.
Memory latency for the 3950X was also only reduced by 5% and 3% for the 9900KS, so based on those figures you wouldn't
