We measured the Core i7 4960X CPU's temperatures using HWMonitor version 1.23. The readings from CPUID's monitoring software varied to those from the Asus motherboard's own utility by up to 10°C. This is something to bear in mind.
We measured the CPU's temperature after five minutes of idling and five minutes of Prime95 load (small FFTs setting). The Corsair H100i CPU cooler's fans were operating from Asus' ‘standard' PWM profile. The maximum fan speed was around 2300 RPM under load.
Our graphs show actual temperatures of the CPU, not delta temperatures. Ambient temperature was maintained at 22°C.
IVB-E seems to operate at pleasing temperatures, even when overclocked using relatively high voltages. By comparison, we put the same 1.40V through our retail 3930K chip (which, due to different LLC settings, was actually 1.408V when loaded, as opposed to the 4960X's 1.424V) and registered a load temperature of 84°C when overclocked to 4.80GHz, and the H100i fans' speeds were higher.
At stock, SB-E received 48mV less voltage than our 4960X sample, but also registered a load temperature that was 1°C higher. CPU cooler fan speeds for either chips were almost identical. Use our temperature readings as a reference only, though, because they were recorded using the Asus motherboard's default PWM profile.
Based on our sample, Ivy Bridge-E seems more forgiving in regards to temperatures than SB-E is. This is good news for users looking to push their CPU voltage higher to achieve greater overclocks, as it doesn't mean that high-end watercooling setups are a necessity. Coupled with the IVB-E processor's lowered power consumption, it also means that watercooling users are given fewer headaches when adding their GPU(s) or motherboard into the loop.
Epic stuff. skimmed over it before work this morning, bookmarked for a good read later today. Next on my list to place my 3930k.
Well at least it seems to overclock a bit better than Haswell. Good info on the core to core tests. 4770k is the most efficient processor on a core basis.
4960x looks like a solid processor, but I wish AMD could offer more of a challenge then Intel would be forced to drop their prices a little. it is very very expensive. Still, for the target audience of people who render etc looks like a great buy.
AMD , where are you!???
Great review, haven’t read all of it yet, but picked up some interesting info. Way out of my price range. im saving for a 4570k and a new mobo. always good reading these ultra high end reviews, just to dream !
wow a lot of work in this one. I do agree with eran earlier in the review. Intel are kick ass, but the prices are hard to swallow. 4770k for a bang to buck is much better, but same with the last generation. these 6 core CPU’s cost a small fortune.
Good work Mr Hill.
best review of this I have read today. I love INTEL!
Ah the perfect partner. Blows the heck out of the FX 9590.
Did ASUS provide a release date for the X79-Deluxe?
LqM, the Asus board will be hitting retailers in the coming days.
Asus would release more boards or just the deluxe?
I wont get the 4770k. 4820 is much better IMO
what are the boot times and boot options on the “Asus X79-Deluxe”?
