AMD claims that the new Ryzen 9 7945X3D with a whopping 144MB cache is the fastest mobile gaming processor on the planet, and that it's more than 15 percent faster than the Ryzen 9 7945HX on average. It has 16 cores, 32 threads, up to 5.4 Ghz boost speeds and 55W+ TDP. The CPU is built on the Zen 4 architecture.

Ryzen 9 7945X3D

I don't know why this name is so funny to me. It just seems so much more ridiculous than an evenly named Ryzen 9 79500X3D. Like what, were getting 45 more units worth of a Ryzen 9 7900X3D, but not quite enough units for a Ryzen 9 7982X3D?

It's because the 7900 and 7950 are using an "old" naming scheme and the 7945 is using a new naming scheme.

  • 7 = released in 2023
  • 9 = Ryzen 9
  • 4 = Zen 4
  • 5 = mobile/APU

One of the side effects of this is that bigger number no longer necessarily means better, especially if you're comparing between architectures

Thanks for the explanation! That makes a lot more sense than what I assumed was an arbitrary number assignment.
