The inclusion of the ‘X3D' i.e. 3D V-cache technology makes this processor hit much harder in gaming scenarios than its core count and process speeds alone would indicate, and gives it a power to price ratio that makes it a fantastic buy: for these reasons we gave it a princely 4.5/5 in our Ryzen 7 7800X3D review. $90 off the asking price ain't nothing to sniff at, so don't miss out on this offer whilst stock is still available! If you can pair it with an equally powerful Prime Day GPU deal, you'll have a standout build for enthusiasts who value real-world smoothness over core-count bragging rights.

What we like about the AMD Ryzen 7 7800X3D CPU

3D V-Cache gaming advantage

AMD's 96MB 3D V-Cache lets the CPU store more game data closer to the cores, cutting memory latency where it matters most. This translates into consistently higher frame rates in games, particularly in CPU-bound and esports titles, when compared to non-X3D chips.

Deals season is here folks, and with it comes huge savings on some of the market's most popular hardware. Below, we be listing today's best PC hardware deals, including GPUs, CPUs, motherboards, gaming PCs, and more.

Excellent performance per watt

The 7800X3D delivers top-tier gaming speeds while drawing noticeably less power than many rival flagships. Lower power means less heat, quieter systems, and more headroom for compact builds.

Better thermals and acoustics

Because it runs efficiently, keeping the chip cool is easier than with many high-wattage processors. That means simpler cooling solutions stay quiet while maintaining boost clocks. The end result is a responsive rig that doesn't roar under load.

Modern AM5 platform readiness

The Ryzen 7 7800X3D is compatible with AM5 motherboards, which bring support for DDR5 memory and for PCIe 5.0 connected storage and GPUs. AM5 boards also bring better I/O, faster USB speeds, and streamlined firmware features.

Easy gains with AMD tuning tools

Precision Boost Overdrive and Curve Optimizer can unlock extra performance without heavy manual overclocking. Small negative voltage curves often reduce temps and improve sustained clocks. It's approachable tuning that rewards a bit of experimentation.

Who's this deal for?

This CPU is tailor-made for gamers who prioritize the highest, most stable frame rates at 1080p, 1440p, and even 4K, and who play competitive titles where CPU latency matters. It's also great for streamers who game first but still edit videos or multitask on the side, thanks to its 8C/16T layout. If you're building on AM5 for a modern GPU and fast DDR5, and you prefer efficiency and quiet over chasing maximum multi-thread benchmarks, this chip fits perfectly.

How the CPU performs

Although if you're looking for multi-core performance you should look elsewhere (we'd recommend the Ryzen 9 9950X), for gaming-focused performance the 7800X3D excels. We said in our 2023 review that ‘if you want a processor that is capable of smashing through any game you throw at it, this is the CPU for you'. It feels snappy, loading large game worlds quickly and maintaining high minimum FPS during heavy combat even on AAA titles. Power draw and temperatures stay pleasantly manageable, the latter even with a midrange air or AIO cooler.
