AMD Ryzen 7 7800X3D Processor | 8-Core 16-Thread | 3D V-Cache | AM5 Socket | 5nm | 120W

AMD Ryzen 7 7800X3D Desktop Processor

The AMD Ryzen 7 7800X3D is AMD’s flagship gaming processor, featuring 3D V-Cache technology — a stacked 64MB cache die bonded directly on top of the CPU chiplet using AMD’s 3D chiplet packaging process. The result is a total of 96MB of L3 cache, dramatically reducing the latency bottleneck between the processor and system memory during gaming workloads. This makes the 7800X3D one of the highest-performing gaming CPUs available regardless of brand or generation. Built on the 5nm Zen 4 architecture. AM5 socket. Requires DDR5 memory.

Compatibility note: The Ryzen 7 7800X3D requires an AM5 motherboard (B650, X670, or X670E chipset) and DDR5 memory. It is not compatible with AM4 motherboards or DDR4 memory. Verify full platform compatibility before ordering. Contact us with your motherboard model if you need confirmation.

3D V-Cache — The Key Feature

• 96MB total L3 cache — 64MB 3D V-Cache stacked die + 32MB standard L3 cache; 3× the L3 cache of a standard Ryzen 7 7700X
• 3D chiplet bonding — AMD’s 3D V-Cache technology bonds an additional SRAM cache die on top of the CPU chiplet using through-silicon vias (TSVs); this increases cache capacity without increasing the CPU’s 2D footprint
• Gaming performance advantage — the massive L3 cache dramatically reduces cache misses in gaming workloads; game data that would otherwise require a round-trip to system RAM is served from the on-die cache, reducing latency and increasing frame rates in CPU-limited scenarios

Use Cases

• PC gaming — the primary use case; the 7800X3D’s 3D V-Cache advantage is most pronounced in gaming; outperforms higher-core-count CPUs in most game titles due to cache latency advantages
• Game streaming — 8 cores / 16 threads provides sufficient headroom for simultaneous gaming and streaming
• General productivity — competent across productivity workloads; note that for heavily multi-threaded non-gaming tasks (video rendering, 3D), the 7950X or 7900X may outperform due to higher core counts and boost clocks
