Intel Core i7 950 

Released June, 2009
  • 3.06 GHz
  • Quad core
5.2 Out of 10

Both of these motherboards work great, but we could have saved ~$100.00 if we were to use a board like the GIGABYTE 880GMA-UD2H which is a great little board and is available for under $100.00.

Reviews Word on the street for the Intel Core i7 950


8.8
4 Ghz was achieved with about 1.27v and 4.4 was with 1.33v. This chip runs really cool as well, but the included cooler is a joke.

What People Are Saying Give it to me straight

Socket Type

Benchmark Results: The true six cores of the AMD Phenom II X6 1100T Black Edition was enough to edge out the four cores plus four threads of the Intel Core I7 950 in the SMP results by 8.6.
by Legit Reviews (Dec, 2010)
In order to combat this we dropped the multiplier back to 22 brought the Bus speed to 197MHz, voltage was sitting at a comfortable 1.325 Volts and we were golden!
by Legit Reviews (Dec, 2010)
When comparing the Intel Core I7 950 to the AMD Phenom II X6 1100T Black Edition they were separated by 12.2fps which is nearly 11% over the Phenom II.
by Legit Reviews (Dec, 2010)

Socket

Once all is said and done, we were able to knock off 26.3% of the time in wPrime!
by Legit Reviews (Dec, 2010)
Granted the margin is small, only ~4.3.
by Legit Reviews (Dec, 2010)
The final gaming benchmark that we ran today was S.T.A.L.K.E.R.: Call of Pripyat, this game lines up the processors how I figured they would be lined up all day, but I'll admit that I have been surprised throughout the day.

Multicore

Colin McRae: DiRT2 shows that our AMD hex-core processors have the edge of the Intel Core Series processors.
by Legit Reviews (Dec, 2010)
That was then, and a new day has dawned or at least the Intel Core I7 950 has gotten a serious price slash.
by Legit Reviews (Dec, 2010)
Does the drop in price for the Intel Core I7 950 mean that we are going to see the end of the Intel Core I7 930?
by Legit Reviews (Dec, 2010)

Performance

As stated the only difference is the frequency, the Intel Core I7 950 trots along at a comfortable pace of 3.06GHz thanks to the x23 multiplier and the 133MHz base clock speed.
by Legit Reviews (Dec, 2010)
Gaming performance shows mixed results.
by Legit Reviews (Dec, 2010)
Benchmark Results: The Intel Core I7 950 was able to knock off nearly 25 seconds from the time it took the Intel Core I7 930.
by Legit Reviews (Dec, 2010)

Overclocking

This CPU was really one of the best ones for overclocking.
by shinigamibob (Nov, 2011)
Now that we have a couple of stable overclock settings, we can see what kind of improvement we can expect.
by Legit Reviews (Dec, 2010)
State of art CPU, very good overclocking capabilities, and mostly noticeable: stays cool even when cooling it with a banana.
