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.

    Can’t wait to read the Userbenchmark review telling me why this chip is actually garbage and how only idiots buy AMD.

      "When using all 16 cores at a TDP of 5 watts, it is actually a lot slower then the core i3-1969UwU, making it pretty useless for battery operation. Consider buying an intel CPU.

      I’m an idiot that’s only ever had problems with Intel. Weirdly, same with AMD/ATI graphics. Only AMD CPU/APUs and GeForce GPUs for this idiot, here.

    This is absolutely ridiculous. Looking at what we get out of mobile CPUs today, when I have a laptop with an i7-7700HQ from 2017 that has… 4 cores/8 threads and is turboing to somewhere in the mid 3GhZ range. With a 45W TDP.

    The last 5 years have been such a turbo charging for CPUs
