AMD "Summit Ridge" ZEN CPU at 2.80 GHz Beats 3.40 GHz Core i5-4670K
According to performance numbers of an AMD "Summit Ridge" ZEN CPU engineering-sample put out by WCCFTech, AMD's claims of IPC gains are gaining credibility, and showing signs of the gaming PC processor market warming up again. An engineering sample featuring 8 cores and 16 threads (via SMT), beat Intel's Core i5-4670K processor. This sample featured clock speeds of 2.80 GHz, with 3.20 GHz boost.
The "Summit Ridge" sample provided 10 percent higher frame-rates than a Core i5-4670K, in the "Ashes of the Singularity" 1080p benchmark. The chip is still convincingly beaten by 12 percent, by a Core i7-4790 (non-K), running at 3.60 GHz, with 4.00 GHz boost. This shows that AMD could leverage the new 14 nm FinFET process to crank up clock-speeds, and produce SKUs competitive with current Intel "Skylake-D" Core i5 and Core i7 processors.

My error was to simply use 'negligent' logic, where 8 is 50 % of 16, 4 is 50% of 8, therefore (falsely) 100% less than 16. Of course, 4 is 75% less than 16.
You know, mathematical mistakes are often actually very interesting. They can almost seem logical.
23 and 30 is so low on the spectrum that obviously you do notice the difference so no, that comparison does not hold up.
But its a good sign that there are already enough ES floating around for leaks like this.
This example of Zen though seems to be slower clocked and would be more competitive if it was faster, they seem to have improved the IPC, although we will have to wait to see if they reached the claimed 40% improvement they wanted.
cpu|max clock|clock ratio|cores|threads|fps|fps gain|intel gain adjusted for clock|amd gain adjusted for threads|amd gain adjusted for threads and clock
Intel Haswell i7|4.0|1.05|4|8|65.4|1.24|1.18|-|-
AMD Zen ES|3.2|0.84|8|16|58|1.1|-|0.93|1.1
Intel Haswell i5|3.8|1.0|4|4|52.6|1.0|1.0|-|-
We would again see 10% better fps on zen compared to i5, if zen was equally clocked as i5 and SMT was off ... and that's with double number of cores
Edit: AMD SMT 8 to 16 threads speedup is projected from calculated Intel HyperThreading 4 to 8 threads speedup, and therefore certainly off by some margin
Now here is zen result on high:
However do note that the Zen benchmark is using mssa, while the other benchmark does not.
Well, they are close and that is half the battle!!! :)
From WCCF's article "the benchmarks given in this article are that of the Engineering Sample of AMD Zen and NOT entirely representative of the final product."
Secondly WCCF just posted/forwarded these benchmarks that some person who had the sample cpu uploaded somewhere, like any site (and case in point here TPU) would do.
So yeah, honesty....
Reminds me of when Intel finally launched it's "Core" CPU's after years of trying to polish the P4 turd :)
Hopefully now we will see some real competition :D
"close" is relative compared to where AMD was compared to where it is.
