AMD Shanghai/Deneb Review Thread

[Ghostbuster]

C2 45nm jumped a lot in Cinebench... thanks to the caches.

The main contributor was the Fast Radix-16 divider which speeds up its FPU operations.

And yes, I'm suspecting what you said. That score was 32 while the Tech Report always benches in 64.

EDIT: Still seems low. Way too low.

Those are 32-bit ones..

We know clock-for-clock that these Denebs are REALLY close to the Xeons in single core rendering... so wtf.
Tech Report 2.7Ghz Opteron Cinebench x64: Single core 3156

If we take this score, scale clock linearly to 3Ghz, times 3.9 (Phenom I speedup), we get 13676. The 32 bit scores are WAY too low.

Nope, you can't scale them up like that. Shanghai scaling probably a bit different in CB10 and this may also apply to Deneb.

TR shows 18616 for 8 cores. Thus speedup is (18616 / 3156 ) = 5.90

Thus scaling per core becomes (5.90 / 8) = 73.7%

Speedup for 4 cores is (73.7% * 4) = 2.95

Thus per core CB10 score hypothethically is (9746 / 2.95) = 3303

Hypothethically speaking, a 3GHz Phenom II scores 3303 per core.

For some odd reason, Shanghai/Deneb doesn't scale well in CB10.. unlike Phenom I...
