AMD Ryzen 7 9800X3D Linux Performance: Zen 5 With 3D V-Cache
Building the default Linux x86_64 kernel on the Ryzen 7 9800X3D yielded similar performance to the Intel Core Ultra 5 245K with its 14 physical cores and narrowly ahead of the Ryzen 9 7900. Going from the Ryzen 7 7800X3D to the Ryzen 7 9800X3D was around a 1.28x speed-up for the build time. Or from the Ryzen 7 5800X3D to Ryzen 7 9800X3D was nearly halving the build time.
The Ryzen 7 9800X3D was delivering nice build speeds relative to the prior Ryzen 7 5800X3D and 7800X3D parts, but ultimately the core/thread count is more important here than the cache size. If primarily compiling code from your system, pursuing the Ryzen 9 9900 series is much better off if your budget allows or as high of a core count as you can afford.
The Ryzen 7 9800X3D was typically pulling more power than the Ryzen 7 7800X3D that was leading to a drop in power efficiency, but still comparable or better to the Intel Arrow Lake competition.
Like with the prior AMD 3D V-Cache processors, the Ryzen 7 9800X3D performs on-par to the other X3D CPUs for Zstd compression performance.
