Hi,
Firstly, thanks for your charts and performance stats!
Can you please double-check the single-threaded stats for the A10-7890k APU (currently: 1720, based on "171 samples").
Verses for example the next model down, the A10-7870k, which is currently: 1571, based on "506 samples"...
I'm finding it difficult to believe that a 200mhz (5%) increase of the A10-7890k (base and turbo clock) verses the A10-7870k would result in 10% increase in single-threaded performance, unless the architecture was different?
Similarly, another 200mhz lower in base and 100mhz lower in turbo of the A10-7870k and we have the A10-7850k, which also scores around 1572 (same as A10-7870k)!?
I would have though a slight increase in clock speed of the same architecture would result in very minor gains (as shown in various benchmarks of the Kaveri architecture), and not a ~150 point increase like with the A10-7890k?
Can you please also double-check the single-threaded stats for the A6-6400k in which my bog-standard setup scored above 1500 points in single-threaded bench using PT8, while your table is showing it as averaging ~1400 points?
Just to breakdown the single threaded scores as per your chart...
A10-7890k = 1720
A10-7870k = 1571
A10-7850k = 1572
A6-6400k = 1403 | mine = over 1500
As you can see, I find the scores for 7890k a little difficult to believe.
Thanks for your help!
