Apologies for the late vid, still emotionally recoving from the recent US news

Either way, AMD is killing it with the gaming performance gains with their newest 9800X3D CPU!

    26.9% performance gain over the 7800X3D

    wow! did they figure out why?

      no idea

      Steve from GN and their team re-ran their tests multiple times and cross-verified with 2 other reviewers as they were also in disbelief/sketched out(I’m inferring their reactions here) by the results.

      So at this point it’s hard to say what’s causing the significant performance uplift.

      It could be due to something in the cpu like the relocation of 3D v-cache, the larger cache buffer but unless we see other reviewers provide test details with some differences it’s difficult to say what exactly is causing this beneficial uplift.

      like what was the tech that caused such a leap? They talk about how they switched up the x3D cache configuration - it used to be stacked above the main part of the chip with some sort of insulation in between, but they found a way to remove the insulation and put the 3D cache on the underside of the chip. I’m no expert and i watched the video yesterday, so sorry if that explanation isn’t clear. Effectively, they found a way to bring the 3D cache “closer” to the cores, which shortens the time it takes for the cores to communicate with the cache.
