I was looking for something else tonight, and found something intriguing, showing that all those 9700/9900 "leaks" are just fakes.
There are alleged leaked benchmarks of the 9900K @ 5Ghz doing 10719 CPU score in TimeSpy, and everyone calls it ultra fast and powerful blah blah.
The numbers do not add up imho, because a 7820X @ 4.8Ghz does 11609 in TimeSpy. A CPU which is has MESH topology, so it will be slower than the 9900K at same speeds, let alone 5Ghz.
While a 5960X @ 4.7Ghz is doing 11007. A much older 8 core CPU tech using RING.
As for 9700K @ 5Ghz (ish) showing the CPU doing Physics 18830 on Firestrike calling it "glorious" performer
An 8700K @ 5Ghz is doing between 21700 and 22600, while a 5820K @ 4.7Ghz still doing around 18500, while my 8600K @ 5Ghz is doing 16217. (on fully patched system)
However if those "leaks" are true, then the reduced performance is down down to spectre, meltdown and other patches. And that is a lot of performance lost with HT on.
But until then, I believe they are fakes.
