  köszi;

  és egy találgatós - a X3D - jövőjéről.

  """
  The second generation of V-Cache’s memory bandwidth and memory latency behavior is very similar to first generation V-Cache where the memory latency and bandwidth is near to identical to the non V-Cache SKUs other than the lower clocking of the V-Cache SKUs. In terms of the SPEC performance, the 9800X3D is ahead of the 9950X in the INT tests and just about makes up the clock speed difference in the FP tests.

  In the end, AMD took what they learned with the first generation of V-Cache along with the MI300 series of accelerators and create the second generation of V-Cache which remediates the biggest weakness of the first generation of V-Cache which was the extra thermal resistance of the support silicon over the cores. This has allowed AMD to both stabilize the boost clock and increase the base clock.

  I wonder what impact this will have on future AMD CPUs with regards to the packaging of their CPUs. Possibly in the future AMD will move all L3 cache into the base tile and just have the cores and L2 cache on top. Or mayhaps they will have more than 1 stacks on future CPUs.
