2nd Gen Intel i7 vs 3rd Gen Intel i7

post #1 of 7
Thread Starter 
Any big differences between the 2nd Gen and 3rd Gen Core i7 CPUs?
If I were to upgrade my 2nd Gen Intel i7 2600K (8M Cache, up to 3.80 GHz) to a 3rd Gen Intel i7 3770K (8M Cache, up to 3.90 GHz) what would the improvements be? 100MHz doesn't seem like a lot.. unless I am missing something? ;P
Also assuming that my Z68 motherboard can support 3rd Gen CPUs?

Thanks!

~5% improvement in IPC (instructions per clock) on average. At stock clocks that translates to about 8% (+100MHz at the 5% IPC improvement).

Much improved integrated GPU if you don't have a discrete GPU handy.

Probably not worth the upgrade given the thermal behavior of these things.

Thanks!

First, a z68 motherboard supports Ivy Bridge (3rd Gen) just fine.

2600k->3770k is not an upgrade, unless you re running at stock. A the same clock speed, the 3770k is 5-8% faster depending on the workload. With the 100mhz stock clock bump, your looking at about a 10% best case scenario improvement. If your overclocked, ive found my 3770k @ 4.5ghz to be on par with a 4.7ghz 2600k.
Power consumption is very much improved if your are concerned about that. At stock, and overclocked. If youve done any reading however, Ivy Bridge tends to hit a wall around 1.3v, the heat becomes to much for most coolers to overcome. Its not that they produce more heat, its the 22nm process combined with the new IHS design has trouble transferring the heat to your cooling solution.

Bottom line: If you building new, get Ivy. If you already have 26/2700k, stick with it as 1155 socket is at the end of its life. Wait for Haswell smile.gif

Slight increase in IPC negated by lower overclocking. Would just stick with 2600K especially if its a good clocker. If running at stock speeds there will be a slight speed boost due to higher stock clock speed and faster IPC....
post #5 of 7
the i7-3770k has support for PCIe 3.0 compared to i7-2600k PCIe 2.0
deafult RAM speed at 1600MHz compared to i7-2600k 1333MHz so ivy bridge has a better IMC

i7-3770k and z77 supports MVP

Ivy bridge has a better IPC so clock for clock ivy bridge is faster but approx 6%

sandy bridge on average overclocks better

your mobo Gigabyte GA-Z68X-UD3H-B3 if it is the rev 1.3 supports ivy bridge out of the box. if your mobo is rev 1 you would have to flash your BIOS to i think F10 or higher, F12 is even better. I am not sure how the new UEFI Bios for these boards is but have hear it is not so good.

if you do decide to go with and ivy cpu, get a 7 series mobo I.E z77 would be the best bet but i think wait for the next gen Haswell smile.gif

dont bother upgrading 2700k to 3770k, no point.
post #7 of 7
I went from a 2600k to a 3770k and there is absolutely no difference in anythign whatsoever. only different is a bump in benchmarks scores.

But gaming or just reglaur usage you will not nothign any differences.
