Massman Posted November 14, 2011 Share Posted November 14, 2011 So, for a long time I wasn't interested in Sandy Bridge-E because it's basically the same architecture like Sandy Bridge and it has the same annoying overclocking problems. Just like with Sandy Bridge, you'll just have to test a lot of CPUs to find a good one (or be very lucky). Last night, I drove too Leeghoofd's place to have one quick test with the platform before it was launched so I would at least have some hands-on experience with it. It was quite a long bench session: from 8PM untill ~3AM ... but of course a lot of fun!! Setup: - Core i7 3960X (ES) - MSI GTX 580 Lightning (x5) - Sabertooth X79 - Dominator GTX8 - AX1200 PSU - Inflection Point CPU pot - Ryba Fat GPU pot OC Results: - CPU clock: 5320MHz - MEM clock: DDR3-2240 CL9-11-10 - VGA clock (3way): 910/1150 and 925/1150 - VGA clock (single): 1450/1200 Vantage and 1500/1200 3D11 - 3DMark Vantage - Performance: 44589 marks with GeForce GTX 580 [-155.0 degrees °C under load] at 1450/1200MHz - 3DMark11 - Performance score: 12034 marks with GeForce GTX 580 [-155.0 degrees °C under load] at 1500/1200MHz - 3DMark Vantage - Performance score: 62985 marks with 3x GeForce GTX 580 at 925/1200MHz - 3DMark11 - Performance score: 19094 marks with 3x GeForce GTX 580 at 910/1150MHz - 3DMark06 score: 40409 marks with 3x GeForce GTX 580 at 925/1200MHz Pictures: Conclusion: So, as expected, Sandy Bridge-E is nothing too special aside from the +5% we can easily get in benchmarks such as Vantage and 11. Aside from those two benchmarks, this chip isn't so interesting for overclockers and even with a gem Gulftown you can get close to the performance of an average Sandy Bridge-E. In Vantage, a 5300MHz Sandy Bridge-E will deliver similar performance like a 6000MHz Gulftown; if you're lucky and find a 5500+ chip, you're safe. Like I've told some people already: I hate the fact that I care so much about the +5% performance gain we can get by using Sandy Bridge-E. Fact is, however, that it's much easier to get a competitive score with this new chip than with the old one ... it's almost as easy like benching Sandy Bridge. Fyi, compare between 3x580 Vantage GT and SBE: - 62919 with 6000 i7 990X - 62958 with 5300 i7 3960X Maxed out GPU completely, need to find better CPU, should probably try the R4E, GTX8 needs to be clocked higher. We'll see. Quote Link to comment Share on other sites More sharing options...
Dualist Posted November 14, 2011 Share Posted November 14, 2011 In Vantage, a 5300MHz Sandy Bridge-E will deliver similar performance like a 6000MHz Gulftown; if you're lucky and find a 5500+ chip, you're safe. Oh good, because getting a 6ghz Gulftown was feckin hard to get as it was. Quote Link to comment Share on other sites More sharing options...
Hiwa Posted November 14, 2011 Share Posted November 14, 2011 Oh good, because getting a 6ghz Gulftown was feckin hard to get as it was. 6GHz GT wasn't hard for me but even 5600 2600k killed me and i never found it hahah, who knows SBE Quote Link to comment Share on other sites More sharing options...
Crew Leeghoofd Posted November 14, 2011 Crew Share Posted November 14, 2011 At least the Pizza was good and the little cat annoying... too bad we didn't nail 5.4 or better CPU... Quote Link to comment Share on other sites More sharing options...
