Comparable CPU to i7-975

Currently running the chip at 4 GHz. What's a comparable stock and current gen i7?
 
Possibly the 2500K. Ivy would be faster so even saying the 3570K would be overkill, but correct me if I'm wrong folks...
 
There are not that many CPUs out 8 threaded 4 core Intel processors to compare. It looks like the IB i7 3770K is better than the i7 975 extreme.

And even the SB 2600K

Although you said running at 4GHz. I guess for that there is no stock x86 CPU that is equivalent to a i7 975 running at 4GHz. A 6 core 12 threaded CPU would be faster at stock in applications that make good usage of the additional cores but at stock I would expect applications that do not make use of 5 or more threads to not be faster than the i7 975 @ 4GHz.

well a 2600k based on clock speed alone as well as cores/threads is equal and can usually clock very high.
i7 3820 gain is equal on the same metrics, and with a decent board are apprently overclockable enough to make a difference(and they have more cache wchich helps in performance)

then there is the mentioned 3770k.

I suppose its just that, you are asking what is comparable, are you asking for overclocking wise, for efficeny etc?

clock speeds alone anything that is comparable to at least a 2600k is at least as good as the 975. The other thing is the nwesr chips and nice boards to go along with them overclock like demons and thier gain is just massive, efficeny of speed and of power.

sandy bridge as well as ivy bridge are faster on a clock per clock basis, I believe it was 10% and another 12% vs first gen core i series.

stock vs stock well, 3570k is a quad core with turbo 975 is a quad with hyper and turbo so they are not the same chip, but that being said, it shows how efficent that 3570 is.
 
X58 has been one hell of a platform.

I may have to upgrade from my i7 970 to haswell-E. We shall see. As a programmer I actually can use more cores provided single threaded performance does not suffer.
 
I'm looking to reduce heat especially come summer time. It idles around 45F and it adds up by mid afternoon making the room 3-4F warmer than the rest of the house. I suppose I could always revert back to stock but I like the performance the way it is. Swapping to a comparable platform is an option but not necessary.

You mean 45C.

Are you on the Northern Hemisphere? If so wait for summer and get a haswell..


Also remember that the temperature of the chip is not what you should care about because a 1W processor at 90C and give off a lot less heat than a 130W processor at 45C. Its the heat output or TDP. i7 975 is a 130W TDP chip. Ivy Bridge is a 77W TDP.

Since the Intel® Core™ i7-975 Extreme Edition was a quad core with hyper threading and support triple channel memory I would say that the closest processor to it now is the Intel Core i7-3820 which is also a quad core and supports quad channel memory. http://ark.intel.com/compare/63698,37153
 
quad with triple or a more efficent quad with dual channel is about the same for virtually everything, that ir the primary reason why most of Intels lineup is using dual channel and only the enthusiats end is quad channel-they ended up making the QPI/DMI by far more efficent on a clock per clock basis, so, something like the 2600k is equal and more oft then not better performing for numerous reasons. I had a buddy the went pretty much through the entire Core i from 800-900-2600k-3770k and the only thing he noticed was slightly better FPS and better multi-gpu scaling, and he rips movies and everything.

exactly my thoughts.
 
What do you do with your current i7 975? Honestly, your question is vague.

I have an Sandy Bridge MBP 13 (Dual Core i7-2.7GHz Early Feb 2011), an i7-920(home) @ 3.6 GHz (w/ Corsair H70 which runs cooler than stock fan), and a Xeon E3-1270 V2 at work. Visual Studio 2012 runs great on all of them and my compile times are short on all of them (except for the MBP, switched back to the HD needed more space.)

I still game on the i7-920 (480 GTX.) I couldn't think of anything else to get for my developer needs that would drastically affect my work. (Gaming too based on what I'm playing.)


EDIT: Actually, I would love more hard disk to run Server and Client VMs with their own hard disk for debugging with VMWare Workstation 9 and Visual Studio 2012. :)

yay someone actually asked what he uses his PC for, should have been the first response rather than suggesting a at best side step to a 2500K :p

I live just outside of Brisbane where its been around 40C (104F) several times in the last week and don't use aircon during the day, run my X58 @4Gh (I7 920), the heat issue is way overstated. A good X58 overclock sets the voltages manually rather than Auto which limits the heat. A lot of reviews i read around the time left Mobo voltages on Auto.
