AMD Ryzen 7 5800X3D
Benchmarks & Specs

Like the AMD Ryzen 7 5800X, the AMD Ryzen 7 5800X3D is based on AMDs Zen 3 architecture. It also has 8 CPU cores, which clock at 3.4 GHz but 400 MHz lower than the AMD Ryzen 7 5800X. The maximum turbo frequencies are 200 MHz lower at 4.5 GHz (single core) and 4.2 GHz (multi-core).

The biggest difference between the traditional Ryzen 5000 desktop processors and the AMD Ryzen 7 5800X3D is the size of the L3 cache. Instead of the already generous 32 MB, AMD now uses 96 MB level 3 cache in the AMD Ryzen 7 5800X3D. Together with the 4 MB level 2 cache, this results in a 100 MB cache.

The cache is made up of 32 MB 2D cache (as usual) plus an additional 64 MB 3D V-cache. The processor is also supported by older AMD mainboards with the 400 chipset series. Of course, the newer mainboards also support the AMD Ryzen 7 5800X3D.

This enormous amount of cache is otherwise only known from server processors. AMD uses a 3D stacking technique here to connect the large amount of cache. This also gives the AMD Ryzen 7 5800X3D its suffix "3D".

Despite the slightly lower clock frequencies, the AMD Ryzen 7 5800X3D is about 20 percent faster in games than the normal AMD Ryzen 7 5800X with only 32 MB cache. In applications, the processor is sometimes faster, sometimes slower. That depends on whether the application can benefit from a fast cache or has been optimized to use the cache.

The processor is still manufactured at TSMC in 7 nm, and the other technical properties are identical to the other AMD Ryzen 5000 CPUs based on Zen 3. The processor can address up to 128 GB of RAM (DDR4-3200), whereby a maximum of two memory channels can be used. PCIe is supported in version 4.0, the AMD Ryzen 7 5800X3D provides 20 PCIe lines for external devices.

• Excellent for gaming thanks to 3D V-Cache
• Based on the efficient Zen 3 architecture
• Large 96 MB L3 Cache
• Solid performance in single and multicore tasks
