Intel Core i5 750 

Released July, 2009
  • 2.66 GHz
  • Quad core
3.9 Out of 10

The board also has 16+3 phase VRM circuits, so it is solid for sure!

The new Core i7 and i5 processors are the first Intel processors to integrate both a 16-lane PCI Express 2.0 graphics port and two-channel memory controller, enabling all input/output and manageability functions to be handled by the single-chip Intel P55 Express Chipset.

Reviews Word on the street for the Intel Core i5 750

Somehow, however, this plucky little quad remains relevant, especially if gaming grunt is high on your list of priorities.



9.3 Out of 10

What People Are Saying Give it to me straight

Socket Type

We were able to reach over 4.3GHz on the Core i7-870 by only increasing the base clock, which speaks volumes on how easy it has become to overclock right out of the box.
by Legit Reviews (Sep, 2009)
The chipset also supports 6 SATA 3 GB/s Ports with Intel Matrix Storage Technology providing RAID levels 0/1/5/10.
by Legit Reviews (Sep, 2009)
The rear IO panel has a pair of PS/2 ports for both the mouse and keyboard, a clear CMOS button, the optical and Coax digital sound output, eight USB 2.0 ports, dual Gigabit LAN, 1394 and ten channel surround sound.

Notice that the processor is only running at 1.2 GHz thanks to Intel's SpeedStep technology.
by Legit Reviews (Sep, 2009)
Benchmark Results: Looking at POV-Ray 3.7 Beta 25, the Intel Core series of processors dominated the top of the performance chart and is far ahead of the other processors.
by Legit Reviews (Sep, 2009)
The Intel Core i7-870 processor is priced at $555, which is more of a higher end sku if you ask us.

The Intel Lynnfield desktop processor lineup does bring some killer performance to the mainstream market, but only the Intel Core i7-860 and Core i5-750 processor are what I would consider mainstream.
by Legit Reviews (Sep, 2009)
In the first run, the benchmark only uses one CPU (or CPU core) to ascertain a reference value.
by Legit Reviews (Sep, 2009)
This is one of the reasons that the processors are so close, but that doesn't help the performance gap with any of the AMD processors.
by Legit Reviews (Sep, 2009)


So what is the difference between a Lynnfield Core i5 and Core i7 processor?
by Legit Reviews (Sep, 2009)
Under certain loads the processors will have the ability to scale up to some pretty high frequency, which is how it does so well against current Core i7-900 series processors.
by Legit Reviews (Sep, 2009)
It will be interesting to see what Intel decides to do with the Core i7-900 series in the months to come.
by Legit Reviews (Sep, 2009)


favourites. It's hardly a slouch when it comes to media encoding, either.
by Tech Radar (Sep, 2010)
This is due to the fact that Intel has changed the integrated memory controller back to dual-channel, brought the PCI Express connectivity onto the processor, and improved their Turbo Mode functionality to offer varying levels of increased performance depending on the type of application being used.
by Legit Reviews (Sep, 2009)
Clearly the Intel Core i7 870 and Core i5 750 processors will have less memory than the LGA 1366 processors since they are just dual channel, but will that matter in real world tests and in the games?

Overclocked clock speed (Air) 4.14 GHz Overclocked clock speed (Water) 3.98 GHz??? WTF??
Well I used to preach about sticking with my i5 750, Well, I got a great deal on a Z77 board and a i5 3470. You can really get spectacular deals on Ivy bridge processors right now. I almost got the i5 4430 at the same price but the haswell motherboards were more expensive. I chose the Ivy 3470 because it's performance is exactly the same and the Ivy boards were much cheaper. So I was able to get a board that has the features I needed ,Crossfire 4 mem slots, Plenty of fan plugs, Good Heatsinks. I got the board and CPU for $270. Not bad at all. And it performs very well. I love how you can set the multiplier on all four cores. You can take the 3470 to 3.8ghz on all 4 cores on the stock heatsink, And it stays cool. Very impressive compared to the temps on the i5 750.
