AMD introduces Ryzen 7 9800X3D with V-Cache on the bottom and it’s a fully unlocked CPU | Infinium-tech

AMD unveiled the Ryzen 7 9800X3D processor, the successor to the 7800X3D. It promises to deliver an average of 8% higher frame rates than the older chip, although some games will see performance increases of up to 26%.

As before, there is a total of 96MB of L3 cache – 32MB on the CCD, plus 64MB on the spare die. Interestingly, this time the 3D V-cache is placed below the CCD (which houses the CPU core) instead of on top like previous iterations. AMD says this helps improve cooling.

The 9800X3D has three pieces of silicon – the CCD (4nm TSMC), the 3D V-cache and the I/O die (6nm TSMC). The L2 cache is 8MB, so AMD advertises the processor as having 104MB cache.

This processor has 8 Zen 5 CPU cores with SMT, i.e. a total of 16 threads. With a TDP of 120W, it runs at a 4.7GHz base clock speed and can boost a single core up to 5.2GHz. The 7800X3D could only do 5.0GHz.

AMD listened to its fans and the 9800X3D is the first X3D processor to be fully unlocked, so if you have the cooling for it, the 5.2GHz ceiling is just a suggestion.

The AMD Ryzen 7 9800X3D is compatible with AM5 motherboards. It will be released globally on November 7 (Thursday) at a price of $480.

Check out the introduction video below – it shows benchmarks comparing the 9800X3D against the 7800X3D (screenshot above) as well as the Intel Core 9 Ultra 285K. According to AMD’s data, its processor is on average 20% faster in games (in terms of FPS), but some titles like cyberpunk 2077 Show a huge gain of 59% for Ryzen processors.
