i7 3960X / GTX 580 Lightning / Sabertooth X79 / GTX8

Recommended Posts

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!!

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.
