Intel Sandy Bridge-E Can Reach Close to 5 GHz on Air-Cooling

As Intel's Core i7 "Sandy Bridge-E" processors in the LGA2011 package inch closer to their mid-November launch, there is already hectic activity among manufacturers of related components such as motherboards, memory, and coolers. By now, a large section of the industry has engineering samples to help design and test their components. OCWorkbench was witness to one such pre-release setup on which a Core i7 "Sandy Bridge-E" (unknown model, could even be quad-core for all we know), overclocked to 4.92 GHz with a "regular" air-cooler. The chip was idling at 45°C.

Sandy Bridge-E, as we know, can be effectively overclocked by increasing its base clock (BClk). On this particular setup, the BClk was set at 120 MHz, with a multiplier value of 41X, and core voltage of 1.51V. The memory used was DDR3-2400 MHz with CAS latency of 10T. This is particularly encouraging, not just to enthusiasts on a tight budget, but also the cooling products industry in general. Core i7 "Sandy Bridge-E" retail boxes don't contain a cooling solution, and Intel has been showing off its branded closed-loop water-cooling solution (to be purchased separately) as something that's "recommended" for Core i7 "Sandy Bridge-E". This gave many an impression that you need at least closed-loop water coolers for any hope of achieving decent overclocked speeds with these chips, and that perhaps these chips are bad overclockers in general. The likes of Xigmatek, Thermalright, Noctua, and Scythe can breathe a huge sigh of relief.

how does 5ghz sbe compare to sb 5ghz speed in super pi? :D

Belgium Massman says:

Coolaler showed there's a 3 second gain from triple to quad channel, I think. In other words: pretty similar. I'd hold on to those 5.7G+ SB chips if I were you.

3seconds sheeeet thats alot.

I assume he's referring to the 32m side of things, 3 seconds difference in a 1m bench would be very big.

Belgium Massman says:

Yeah, 3 seconds in 32M. That's like 20MHz CPU or so.

with current BIOSes, SBe is slower at same clocks by a good dozen seconds compared to "regular" SB

:D

United States Hondacity says:

About the "current bios" does that include all of the x79 boards? I'm still expecting an improvement over the 67/68 chipsets, given Intel has always been consistent with "superpi".

TaPaKaH says:

I don't know about ASUS, but out of Gigabyte/MSI/ASRock trio, the fastest 32M at 4GHz I heard of is 8min16 (8min05-07 is easy with 1155).

Germany Afrokalle says:

I hope with final (performance) bios Sandy Bridge-E will be the new 32M King. But much more i hope for scaling with cold and voltage coz SB 2D benching is boring atm...

I can agree with this one, I got 8m16.xxx s using i7 3960X @ 40x100 + Quad Channel 2133Mhz 9-11-9-27 1T ram on winXP (no copy waza yet). Using i7 3930K at the same configuration got me 8m19s.xxx.

What really disturb me was AIDA64 memory bandwidth/ Maxxmem figures in SB-E, all of them is inferior compared to the 2600K at the same clocks, especially the write/copy bandwidth. I also see Little to nothing bandwidth scaling when going from Dual Channel vs Triple Channel vs Quad Channel in SB-E.

As far as i tested, SB-E only shines at 3DMark2011 Physics test (got 136xx in 4Ghz, 2133Mhz Quad Channel, took a 5.5-5.6Ghz++ 2600K to match that), but in less-threaded benchmarks 1155 SB beat SB-E in the same clocks.

Difference between 3960X and 3930K should depend on cache...

Maybe AIDA64 need update for SB-E to show real performance (was with older cpu's + new chipsets the same).

In 32M big cache and quad channel must give some advance - i think we must wait for right bios and i hope that SB-E will not only kick ass in multi-threaded benchmarks...

Indonesia Lucky_n00b says:

Hondacity said: lucky!

Tested at my friend's review office yesterday on both GD65 8D and P9X79 Pro(both performance were identical).As for clocks, now i got stuck at 5Ghz on both board, same 'clock wall behaviour' as the previous SB (T_T).

Will test if it scales under cold after full review was done ;)

@lucky

I think the wall will be inherent to the cpu design, it is still sandy bridge. but i think the imc bandwitch should at least improve. I'll await further developments for this platform.

are you testing retail cpus? or es?

United States Hondacity says:

kenny

i know you want bd...hahahhaha

I just wanna know if this one scales on cold again or whether it's boring like the normal SB

For the fun of scaling with LN2, it's a thought...... just add 30% performance and minus 45% power consumption an i'm there

I'm still trying to get infos about the rumored retail SB-E chips which supposed to be distributed somewhere in Asia, but no good lead so far.

Romania matose says:

Most SB-E will clock 5-1-5.3GHz, the really good ones will do 5.6-5.7GHz. No reason to bench SB-E except 3DMark 2011 and Vantage, especially with multicard (4-way scores are much better that x58)

Belgium Massman says:

Gulftown can clock much higher than SB-E, so it won't be competitive in the 6xCPU rankings.

Canada Eldonko says:

What a disappointment then. :( I hope we see an improvement with retail chips.. ES are always a little off for perf and dont oc well.

With the exception of Clarkdale & Gulftown :D

United States sin0822 says:

I bet retail will be better just like with SB, but can someone with SB-E test instead of AIDA test Sandra?

maybe intel has another trick up their sleeves, again to make ES CPUs not part of the game, makes sense to me.

Maybe its with final revision BIOS, something like CPU PLL OCP lol.

it seems that the previously announced prices are correct, no significant rise o prices cause FX fail ... previous prices were: 599 + 999 USD. UK is alway most expensive market in Europe. US prices will be 599 + 999 USD.

United States sin0822 says:

What do you mean second strap? IMO this board is a mix between the OC board and the UD7, you got OC board features, but also UD7 features like connectivity. So Id think itd sell better than the X58A-OC b/c that board turned away a lot of normal consumers who wanted normal functionality, but also the e-peen of owning an OC board with features they wont use. In terms of the feel of the board, it feels like im using my X58A-OC, i really like it. BTW the BIOS is snappy with a keyboard, and there is no need to use a mouse, all the ways to change settings in GB's AWARD BIOS are still present, like using Page up and page down to quickly disable or enable or raise and lower settings. The PWM control settings are pretty abundant, very high setting ranges.
