AMD Ryzen 7 7800X3D Build and Breakdown - Now at Micro Center!

This discussion has a more recent version.

Written by Sean Mekinda

Just a bit over a month ago, AMD launched their Ryzen 9 7900X3D and 7950X3D processors, ushering in the next generation of the "World's Fastest Gaming Processor." Today sees the launch of the newest chip in their X3D lineup, the Ryzen 7 7800X3D. Built on the same 3D V-Cache technology as its siblings, the 7800X3D is designed to bring high-powered gaming to gamers building on a tighter budget.

What's The Difference Between Non-X3D and X3D Chips?

The simplest answer is that X3D chips are made specifically for gaming, while non-X3D CPUs are a jack-of-all-trades. The addition of AMD's V-Cache technology adds a massive amount of extra L3 cache memory which can have a great impact on CPU-based games. On the flip side, that 3D V-Cache does limit the productivity capabilities of the X3D lineup (though mostly just in comparison to the non-X3D chips - they're still quite packed with power).

To put it plainly: if you're build a PC for gaming and want to get the absolute most out of it, go with an AMD X3D chip.

What Is 3D V-Cache?

3D V-Cache is nowhere near as complicated or as dauting as it sounds. It is, quite literally, an L3 "cache" extended "V"ertically into "3D" space. This extension enables far greater memory capacity over traditional chips. The Ryzen 7 7800X3D has three times the L3 cache as the 7700X, the chip next to it in the AMD CPU lineup. Unlike it's X3D siblings, however, the 7800X3D does not have a second core-per-CCD (or Core Complex Die, sometimes referred to as a chiplet. Essentially, they are a second, smaller chip on the base CPU) to offload non-gaming processes to. While this may impact non-gaming processes, most users shouldn't see much of a difference, so long as non-gaming work remains relatively light. If you want to make the most of that 3D V-Cache, check out our build guide below!

AMD Ryzen 7 7800X3D Build Guide - The Killer Gaming PC

AMD's Ryzen 7 7800X3D is an absolute powerhouse, even when compared to its older siblings. Early reviews have it cranking out incredibly high frame rates and living up to the 5800X3D's incredibly lofty legacy. So, in honor of this new pinnacle of power, we've designed a build to really let it shine!

ProcessorAMD Ryzen 7 7800X3D Raphael AM5 4.2GHz 8-Core Boxed Processor

The power of the X3D processor really is all it's cracked up to be, and there's no better proof of that than the Ryzen 7 7800X3D. This mid-tier processor delivers framerates that rivals - and sometimes surpasses! - some of the best processors on the market.

The Ryzen 7 7800X3D doesn't come with a cooler, so you're going to want to pick one up. We'd recommend an AIO to really get the most of the CPU - something like the Corsair iCUE H150i ELITE would work great!

Motherboard: ASUS X670-P PRIME AMD AM5 ATX Motherboard

ASUS's X670-PRIME is a stylish motherboard. There aren't a lot of extraneous bells or whistles and no RGB, leaving you with a board that has to stand on its own, and boy does it. Using simple silver accent colors on a black base, the X670-PRIME will give your build a fantastic starting point.

The PowerColor AMD Radeon RX 7900 XTX will draw every ounce of gaming power out of the 7800X3D, ensuring you're seeing top-of-the-line performance in any game you boot up. From the latest AAA titles to high-end esports, you'll get high frame rates and gorgeous visuals. Plus, that splash of RGB in the fans will give the build just a pop of internal lighting.

RAM: Corsair Vengeance RGB 32GB (2 x 16GB) DDR5-5600 PC5-44800 CL36 Dual Channel Desktop Memory Kit CMH32GX5M2B56WK - White

Speaking of pops of internal lighting: white Corsair Vengeance RAM. These two sticks of 16GB DDR5 RAM aren't just blazing fast, they'll blend seamlessly into your motherboard thanks to their white aesthetic. But if you're looking for a bit more flair, flip on the RGB and let the the RAM speak for itself.

Hard Drive: Inland Performance Plus 2TB M.2 SSD & Seagate BarraCuda 4TB 5400 RPM HDD

You've got a blazing fast processor, a top-of-the-line GPU, and DDR5 RAM. Don't limit your build by using a traditional HDD as your main storage drive. Inland's 2TB Performance Plus M.2 SSD enable lightning-fast boot times and has plenty of storage for all the games your regularly play. If you need more space, the Seagate BarraCuda has you covered, with an additional 4TB for games, documents, and backups.

Power Supply: Corsair RMx Series RM850x 850 Watt 80 Plus Gold ATX Fully Modular Power Supply

When you're putting together a build that looks as good as it is powerful, the worst thing you can do is use a standard PSU. Fully modular power supplies let you pick and choose which cables you actually need so you don't have a rats nest tucked away in the bottom of your case. Plus, it makes cable management way easier!

Case: Lian Li Lancool II MESH Type C RGB Tempered Glass ATX Mid-Tower Computer Case - Snow White

Lian Li makes stunning cases that are ridiculously easy to build in. I went with the Snow White version of their popular Lancool II to give the inside a darker look, but you could swap it for the black model if you want those streaks of white to be the accent color, rather than the focus.
