Cherry-picked internal benchmarks
Quote: "To this end, Intel released flurry of cherry-picked internal benchmarks that show its new chips besting the two-year-old 5950X and going toe-to-toe with AMD's SRAM-stacked 5800X-3D in a selection of games and productivity apps."
Also worth mentioning they included the specs for the test environments for these benchmarks linked on the slides, and Intel basically didn't set a level playing field. (Shocked I tell you! Said no one). Copy of the slide here (on reddit).
The new Intel system was sporting fast premium 5600 DDR5 memory.
Whereas they fitted the Ryzen systems (5950X and 5800X3D) with 3200 DDR4 memory.
Lots of people complaining about this, as anyone who knows Zen (at least for 2 & 3), knows you generally fit 3600 memory [*], otherwise you gimp the performance of the CPU. You can easily drop around 5-15% in game FPS by using 3200 RAM instead of 3600 RAM.
Also the fact that Intel focused on the 5950X for gaming benchmarks is just odd! The 5950X is not a gaming CPU, with other chips in the range actually being faster for gaming (even before the 5800X 3D). Basically if you're gaming, you want no more than 8 cores, so that you have a single CPU chiplet. More than 8 cores means two chiplets, and the increased latency between them impacts gaming (although doesn't really impact productivity type workloads, and the game impact depends on the specific game).
The 5800X 3D data is in there, but almost as an afterthought, as they just added a tiny little mark on the chart, rather than a new bar, almost as if they were hoping people wouldn't notice the data! Someone on Reddit actually put the bars back in :-) link
With the nobbled RAM, the 5950X and 5800X3D scores likely need to be at least 5%+ higher than they actually are at the moment. Which means over all, the 5800X3D still leads.
As always, for real data, wait for someone like Hardware Unboxed or Gamers Nexus to get hold of the new Intels (they already have the new Ryzen CPUs tested). As they actually know how to do benchmarks!
* In case anyone doesn't know, running the Infinity fabric frequency at a 1:1 ratio with RAM speed, gives best performance in Zen. So 3600 RAM, as it's double rate, runs at an 1800Mhz, same speed as the Infinity fabric. You can also do 3733 RAM and infinity fabric at 1866Mhz for even better performance, but 3733 RAM is less common and some systems can have stability issues.
