Hi Folks

Today i have ran a few quick benchmarks on the new Intel Core i5 670

this chip can be purchased here on the OcUK website

this is just to give you an example of what can be achieved on these amazing new processors.

The following benchmarks were gained using a single stick of Gskill Ripjaw 2000MHz and the incredible Asus Maximus III Formula Motherboard.

Please note
All of these results were gained using an air cooler and are in no way sustainable for long periods of time



Starting Off - we have a nice 4.6GHz run with HT disabled just to get into the swing of things

this gave impressive resilts in Super PI

and also in Wprime 32m and 1024m

Pushing Further
4.6 was fairly easy as it involved increasing the multi to its max setting [27] and then compensating with lots of voltage.

after this we tried for 5ghz+ as the board is capable of 200+BCLK
giving a theoretical [200+X27]=5.4+GHz

I also turned hyperthreading on for this run to see if it would run without causing stability issues

Wprime 32m and 1024m saw nice improvements

cinebench stopped running on multiple cores after 4.95GHz so i chose not to document any scores

here is an 8second SuperPi 1M @ 5GHz

and the validation screens

with top end system stability at around 4.6GHz and 5ghz a realistic possibility
these chips really are something special.
 
The very interesting fact is with high end watercooling (and not a cooler that has been fitted 1000 times already) extreme clock speeds could be easily sustainable.

Also worth noting that Rich set these benchies up during a 40 minute period of time, so no three day prep time or anything silly.

Prolimatech Megahalems with the fan from a Titan Fenrir, by far not the best cooling on the planet and done in a rush. Just shows what these chips can do.
 
Assume 4.6 stable would be doable with high end air. I know HT is no substitute for Quad Core but how badly do they lag behind an i7 running at 4 (without HT enabled) and the above chip at 4Ghz with HT enabled?
