Intel i5 760 Review
Sandra and wPrime

SiSoft Sandra
Processor Arithmetic
Now here is something different. The Processor Arithmetic of the SiSoftware Sandra benchmark suite uses what are called Dhrystone and Whetstone tests on the CPU. Dhrystone has been with us for over 25 years and measures Integer calculations of a CPU, whilst Whetstone is older than I am and measures Floating-Point calculations.
The extra threads available on the i7-870 help it to edge out even the overclocked i5-760 in the Whetstone test. Once we move to the Dhrystone test the i5-760 just wins out both in overclocked and stock form. Although clearly the Dhrystone test loves CPU cycles more than anything as once the overclocked i5-760 is ignored the other three CPUs are neck and neck.
Moving to the Processor Multimedia test which uses the CPU to generate a Mandelbrot fractal (a very intensive task) we see normal service resumed.
wPrime 95
Our final bunch of mathematical benchmarks is wPrime which really pushes the processor and memory to its knees in a quest to perform a set number of calculations as possible as fast as possible.
Because the benchmark is considered successful the shorter amount of time it takes to complete, similar to rendering, the graph is an inverse of our others, but the results remain the same. The incredible performance available from the i5-760 is sufficient to see it overcome the extra performance of its hyper-threaded big brother.

I only chucked my new 760 in my also new P55-UD5 last night and redone my loop.
Never ever overclocked on the P55 / X58 platforms before but it took about 3 mins to work out how to up to 4GHz at 1.23v with memory at 2000Mhz.
Tried to quickly chuck it up to 2133MHz with an overclock on the CPU of 4.26 GHz but at that voltage it only just booted into Windows.
When I've rebuilt my OS, I'll get some proper overlocking done on it.
Oh yeah, temps while Prime95'n overnight hit a max of 59 degrees.

not a bad little chip is it! Make sure you start a thread about your journey with it dude.Great vid, just ordered myself a Core i5-760, Asus P7P55D-E Pro and 4GB Corsair Dominator GT (2000MHz) kit that should get delivered this weekend. I'll be replacing my old Athlon 64 5000+ (lol!), already got an Antec 300 full of fans and a Corsair H50-1 Water cooler which should keep it cool and quiet. I'll also be using a Corsair HX550 PSU and BFG 8800 GTS 640MB OC2 to round the system specs off.
I've never tried overclocking before and would love to clock this upto the 4GHz you got but without using much overvolting. Is it really as simple as upping the Base Clock to 200, dropping Multiplier to 20x, voltage to 1.250 (That's the VCORE yeah?) and manually setting the RAM timings to match the modules rating? Is there anything I've missed?
Also, I know to do a clean install of Windows before stress testing but whats the best stuff to do my testing? Am I right in thinking clean Windows 7 Pro x64 install, install required drivers, leave off the net without installing any A/V and then starting my stress testing with sometime like Prime95 for a couple of hours, then move onto something like 3D Mark Vantage, Unigine Heaven for another couple of hours.
Is there anything else I've missed of need to know?
Thanks!
