AMD Ryzen 7 3800XT vs Intel 9th Gen Intel Core i7-9700K: Comparison
AMD Ryzen 7 3800XT vs Intel 9th Gen Intel Core i7-9700K l3 cache compared
The gap that matters here is l3 cache: AMD Ryzen 7 3800XT 32 MB against Intel 9th Gen Intel Core i7-9700K 12 MB, which puts AMD Ryzen 7 3800XT 63% ahead. Blender Cycles (CPU) backs the spec sheet up. AMD Ryzen 7 3800XT scores 191 to 136 over 14 runs, 29% clear. L2 cache runs the same way, 4 MB on the AMD Ryzen 7 3800XT versus 2 MB on the Intel 9th Gen Intel Core i7-9700K, another win for AMD Ryzen 7 3800XT. Pcie lanes runs the same way, 20 on the AMD Ryzen 7 3800XT versus 16 on the Intel 9th Gen Intel Core i7-9700K, another win for AMD Ryzen 7 3800XT.
Which should you buy, AMD Ryzen 7 3800XT or Intel 9th Gen Intel Core i7-9700K?
Take the AMD Ryzen 7 3800XT for gaming and productivity desktop builds wanting the highest-clocked 8-core Zen 2 performance available. It is the wrong buy for buyers with access to Zen 3 chips, those offer a real architectural step up over even the fastest Zen 2 silicon. Take the Intel 9th Gen Intel Core i7-9700K for gaming-focused desktop builds wanting strong 8-core per-core performance without paying for the i9-9900K's hyperthreading. Avoid it for buyers needing maximum multi-threaded throughput for content creation, the 16-thread i9-9900K handles that better.
Which is cheaper, AMD Ryzen 7 3800XT or Intel 9th Gen Intel Core i7-9700K?
At the last price check the Intel 9th Gen Intel Core i7-9700K was $374 and the AMD Ryzen 7 3800XT $399, a 7% premium.
