Intel Core i7 920 

Released October, 2008
  • 2.66 GHz
  • Quad core
3.9 Out of 10

Pros: You can get a 50% Overclock instantly,Great processing Bandwidth,Nice HUGE heatsink,L3 Cache size.

Even when the 950 was overclocked it usually did not make it far past where the 920 could go, making the 920 the best option by far IMO.

Reviews Word on the street for the Intel Core i7 920

Sandy-Bridge will be cheaper than LGA1366 while also giving better performance in video-editing and other applications so if you need something cost-effective then go with Sandy-Bridge but if you can get a deal on a i7 920, go for it.

What People Are Saying Give it to me straight

Socket Type

It was a high end CPU with HT tech that almost everyone could afford and overclocked extremely well for people who wanted more power without paying $500 for the 950.
by hfcobra (Jan, 2012)
4 GHz was generally easily attainable (I put mine straight to 4 when i installed it and never looked back).
by IEATFISH (Nov, 2011)
Very fast, it's never reached over 90% load and I do sony vegas 11 and photoshop CS5 work all the time.
by cards525 (Feb, 2013)


With a good overclock it actually ran much faster than the 950.
by hfcobra (Jan, 2012)
When this chip first came out, it was sort of a holy grail of overclocking.
by IEATFISH (Nov, 2011)
Ever since I bought it I have had a 4.2 GHz overclock on it and never had one stability issue after I initially gained stability.
by hfcobra (Jan, 2012)


I have been running close to 4Ghz for 1.5 years with no problems, this processor can handle most modern tasks thrown at it, although with the speed with which technology advances, I must say that it's slowly starting to show its age, since the original models were released a bit more than three years ago.

For the price and performance, it was hard to beat the 920.
by IEATFISH (Nov, 2011)


But while it may beat SB in that sense, the part where Sandy-Bridge processors win in is cost to power ratios.
