AMD Ryzen 7 9800X3D (8-core, Zen 5, unlocked)

Our analysis

Unlocked against locked, and 104 MB of cache against 20 MB: next to the Intel Core i5-14400F, the spec sheets put eight Zen 5 cores on AM5 against ten hybrid cores on LGA 1700. The i5 is a chip swap for a board you already own; this one is the processor you build a new AM5 gaming PC around.

What stands out

• Cache under the cores. AMD moved the 3D V-Cache below the compute die on this generation, which is what lets it run at higher clocks than the 7800X3D: 5.2 GHz boost against 5.0, per AMD.
• Unlocked multiplier. AMD allows overclocking on this X3D chip, which the 7800X3D does not.
• 104 MB of total cache and a 120 W rating. Games that keep pulling world data, like simulators and large open worlds, are the case a large cache is built for.
• Integrated Radeon graphics. You get a picture without a graphics card installed, which helps when troubleshooting.

Where it falls short

• In TechSpot's 12-game test at 1080p with an RTX 5090, it led the 7800X3D by about 8%. That is the setup where the processor matters most; with a mid-range card at 1440p, the graphics card sets the limit sooner.
• No cooler ships in the box, and its 120 W rating calls for a capable one.

Look elsewhere if

Your monitor is 1440p or 4K and your card is mid-range: the Ryzen 7 7800X3D has the same 104 MB of cache at a lower price. If your games are limited by the graphics card, the Ryzen 5 9600X keeps you on AM5 and leaves room to upgrade later.
