New Passmark baseline for the A10-7850K has appeared and almost hits the predicted 6000 points scoring 5997 points at stock

Other baselines at stock for Steamroller

The average of the three is 5874. I wonder who submitted this crippled baseline for Kaveri and why

In the above baseline Kaveri was crippled at Trinity level of performance

It looks better than I expected: the A57 core is about 35% faster than the jaguar core with the bonus of consuming much less power! This implies
8x
Steamroller cores @2GHz would hit ~60 SPEC_int
8x A57 cores @2GHz hits ~80 SPEC_int
Thus A57 cores are above the Steamroller level of performance (I predicted they would be at the same level, but A57 cores are finally better).
Regarding floating point:
8x
Steamroller cores @2GHz offers maximum of 128 GFLOPS
8x A57 cores @2GHz offers maximum of 128 GFLOPS
It is now made evident why AMD abandoned the 4/6/8 core Piledriver based Opterons, why is releasing the new 12/16 core Warsaw Opterons only for legacy customers, and why doesn't release any Steamroller based Opteron. An 8-core Opteron obtained from dual packaging quad-core Kaveri CPUs (plus extra L3 cache)
would be slower and inefficient than the new Opteron A1100. And without Steamroller Opteron there is no Steamroller FX.
It is worth to mention that the 16 core Warsaw Opteron offers 2.6 GFLOPS/W whereas the new 8 core Opteron A1100 offers 5.12 GFLOPS/W, which is ~4x the efficiency of Piledriver! Recall Steamroller is only 10-15% more efficient than Piledriver.
All those who said that ARM was low performance and that couldn't match x86 in decades were wrong. Another of my predictions in this thread has been verified.
Those who claimed here that a friend at AMD supposedly said him that ARM is an experiment would read what AMD said during the presentation of the new Opterons:
After the announcement at the OpenCompute Summit we had the opportunity to discuss the impact of the new ARM server processors on AMDs business with Andrew Feldman. The most interesting aspect lies in the significance of the x86 and ARM technologies for AMD going forward. As current forecasts show, by 2019 CPUs based on an ARM architecture will comprise 25% of the server market, with the remaining 75% still being x86 based. However at AMD, Mr. Feldman actually expects a fifty-fifty share at AMD by that time.
And custom cores such as Nvidia Denver will be better than standard A57. There are rumors that AMD will release custom cores for Cambridge SoC.
I predicted in this thread, that we would see Kaveri paired with a 290. I predicted this when I discussed the slide #13 of a talk given to OEMs by AMD. My claims received a lot of criticism then, but they are confirmed now.
AMD is providing also some MANTLE performance gains for Kaveri+290
BF4:
40.9% (1080p) and
40.1% (1600p) performance improvement under Ultra settings and 4xAA on the AMD A10-7700K with an AMD Radeon™ R9 290X.
StarSwarm:
319% (1080p) and
281% (1600p) performance improvement in the “RTS” test on Extreme settings with the AMD A10-7700K and an AMD Radeon™ R9 290X.
