With the overclocking done, how does it all perform? I have not completed direct comparisons for you just yet (those will be coming soon), so I’m including a small sampling of scores taken from the HWBot database to compare clock for clock performance improvements per bench. Keep in mind, these comparisons have other variables, such as operating system and driver efficiencies….so view the comparisons with a grain of salt.
Intel CPUs at 5.1GHz - SuperPI 1M
AMD CPUs at 5.1GHz - SuperPI 1M
Nothing too surprising here, nice efficiency improvements from the older Intel architectures, and of course AMD trails a lot in SuperPI. It has not been AMD’s strong suit since the K8 days.
Intel CPUs at 5.1GHz - SuperPI 32M
AMD CPUs at 5.1GHz - SuperPI 32M
Very similar story here, but Bloomfield and Gulftown are able to close the gap a bit with triple channel memory.
Intel CPUs at 5.1GHz - Hexus PIFast
AMD CPUs at 5.1GHz – Hexus PIFast
Sandy Bridge shows a pretty nice gain here as well, that L3 cache at full speed likely making a big impact.
Intel CPUs at 5.1GHz - wPrime 32M
AMD CPUs at 5.1GHz – wPrime 32M
Intel CPUs at 5.1GHz - wPrime 1024M
AMD CPUs at 5.1GHz – wPrime 1024M
I find it quite interesting that Thuban matches Sandy Bridge performance so closely in the wPrime benchmark. Of course, those Thuban CPUs are not running on air cooling.
From this point forward, cross referencing HWbot becomes quite tedious, so I won’t include them for the following.
I’m very impressed with the MaxxMEM2 result here. Despite only being dual channel, this rivals the best results from Bloomfield/Gulftown. MaxxMEM2 records will be broken with Sandy Bridge.
CINEBENCH 11.5 is also very impressive, breaking the 10 point mark. Gulftown with similar clock speed is only about 20% faster here.
Again, we see great power in Sandy Bridge with Aquamark3. The fast L3 cache is likely helping a lot in this benchmark.
3DMark 03 is a very GPU dependent benchmark, so the real star in this result is the GTX 580 on my test platform.
3DMark 05 is just the opposite, requiring high CPU, cache, and memory speeds for a good result. This score is nothing to sneeze at.
3DMark 06 is heavily CPU core speed dependent, and this score is very efficient for a 5.1GHz clockspeed.
This 3DMark Vantage result is probably an air cooled single GPU world record (hehe).
I’m still learning 3DMark11, and don’t have much to say about the result, but it does seem to be pretty good.
The Unigine Heaven benchmark is heavily GPU dependent, so again the GTX 580 is the star in this result.
