AMD 45nm Deneb Pictures, CPU-Z and Super Pi Results

[Epsilon84]

With all due respect achieving such a speedup in a canned benchmark rarely translates to real world performance, a point I'm sure you appreciate. As terrace215 suggests the increase could purely be due to the larger cache, taking what amounts to pre-lunch hype at face value usually leads to dissapointment. The superpi figures are interesting but without more system level test results, proclaiming AMD IS BACK!!! at this point is premature.

I'd agree. If it was a 12.5% jump in something other than SuperPi, I would have been really impressed. However, SuperPi is quite sensitive to cache size, and a 12.5% boost in SuperPi generally does not correlate to same increase in most real world applications, unless the application was also very cache dependant. For example, when comparing C2Ds of different cache sizes we get:

( Source )
E6600 (4MB L2) @ 3.5GHz ~14.7 secs
E6400 (2MB L2) @ 3.5GHz ~16 secs

An E6600 is ~9% faster than an E6400 per clock in SuperPi, but the real world difference between the two is actually only ~3.5%.

Now considering we are comparing a Phenom w/2MB L3 with a Deneb w/6MB L3, could it be possible that the majority of the performance increase is down to the much larger cache?
