Ivy Bridge 7 GHz Rips Through Pi
Intel Core i7-3770K is turning out to be a monstrous overclocker, when assisted with extreme cooling such as liquid-nitrogen. One such test-bed, was overclocked close to the 7 GHz mark, and put through Super Pi (1M and 32M), and PiFast. At 6961.6 MHz, the chip ripped through Super Pi 1M, in 5.187 seconds. The same chip, clocked at 6650.1 MHz, crunched Super Pi 32M, in 5 minutes, 2.843 seconds.
In PiFast, with a clock speed of 6805.1 MHz, the chip hammered out a total computation time of 10.56 s. NordicHardware compiled a comparison table using HWBot and its own data, to reflect how much faster a ~7 GHz Core i7-3770K is, at Pi. The rest of the known test-bed consisted of ASUS ROG Maximus V Gene Z77 motherboard, and 4 GB (2x 2 GB) of dual-channel DDR3 memory, clocked at around 2652 MHz, with timings of 7-11-7-28-1T.

this is very nice indeed. I wonder if we will ever see another 7ghz CPU, as this is E0, no one is using E1 for extreme, and it seems E1 has better air OC, and those nice 5ghz with lower volts are done on E1, E has those terrible air/water, so it has higher leakage and thus performs like this. I wouldn't like it if only E0 ES did well, because then you can't compete with retails.
Whats going on with that graph and its info though, no stock 3770K on it and why does a i7980x still hold the world record? with 6.042 Ghz and a slower time too, and i take it thats a world record for an all cores on OC , as AMD got 8.something out of an Fx with 1 core running?
and another thing why has performance not improved very much , nigh on 11% improvement over a 980X with 30 extra clocks and a generation swap and shrink ,between the two?? sounding a bit BD this increase

Anyone know of a OpenCL Pi program?
I think sticking with the topic at hand might help. :D

Regardless Ivy Bridge is looking impressive. When I find more leisure time I'm going to be upgrading to Ivy.
:wtf:
