Hey my friendly geeks,

The question is pretty much the title, can Intel Gen. 2 cpus use PCIE 3.0 expansion cards (e.g. Graphics Card)?

Thanks a lot.

My Build:
Case: Xigmatek Asgard Pro Black Edition Motherboard: AsRock Z77 Extreme 4
CPU: Intel 3rd Generation i5-3570 @ 4.2 Ghz Graphics Card: Asus HD 7770 1 GB GDDR5
RAM: Adata 4GB DDR3 1333 X 2

I'm pretty much sure that only 3rd gen "Ivy" can use pci-e 3.0, the sandy are limited to 2.0 because it use the old controller...

Gaming PC: MSI Z77A-G45 ::: Intel Core I7 3770k @ 4.83Ghz ::: EVGA GTX680SC Signature ~1300mhz Boost/7122mhz ram ::: 16GB 4*4gb G.Skill 2240mhz CL10 ::: ASUS Xonar DX ::: Crucial M4 128gb (windows) + Intel 330 180gb (Steam games) + 1TB Caviar Black (storage) ::: Cooler Master Silent Pro Gold M1000 ::: Antec P280 ::: Noctua NHU12P SE2 ::: ASUS VE247H ::: Logitech G510 ::: Cooler Master Storm Sentinel II ::: Logitech X530 ::: Steelseries Siberia V-2 Black & gold edition

The main PCIe controller is on the CPU now. You must have an Ivy Bridge chip to use it.

Thanks a lot spawnkiller, I realized the same thing as you say after a little bit of research. I asked this because I think it is really strange for motherboard manufacturer to make PCIe 3.0 ports for LGA 2011 socket, since (as I remember) only Sandy cpu uses LGA 2011.

Anyway, thanks a lot for your reply.

SBe is a different monster from SB on 1155. It has a lot of the tech used in IB, but is not built on the 22nm process.

I do not understand, Intel always have products that does not have significant improvements but makes the products that works with the cpus (i.e. motherboards) need to be changed, and this is annoying cause I really don't have a whole lot of money.

Also, I think the prices of the products are not really reasonable, a good example are the Xeons cpus, have really high prices, but don't seems to have really high performances.....

Xeon is dedicated for server/workstation not games, one Xeon compare to an i7 in rendering/server use is 10 times faster than a 3960x...

so what's your opinion? should I get a i7 or Xeon if I wanna render things?

Thanks a lot.

Only rendering or gaming too cause that will change from Xeon (only workstation, not a real gaming capable CPU) to an I7 that will doo gaming far better and is capable to rendering video too (and fast enough for casual/weekly rendering)

PS: it's not 10 times faster, but it's faster, also you could match 2 xeon on one motherboard to do a high-end workstation and they are very optimised for workstation use so even with tie score in benchmark, they will outperfom any I7 in rendering or multimedia...

In arithmetic E5-2687W scores: 320.9 GIPS and 540.47 GFLOPS
I7-3960x scores: 132.5 GIPS and 217.54 GFLOPS

Passmark CPU score: [New Xeon E-7 V2 will come out soon (10 cores/20Threads)and replace current E7 (4c/8t)]
Intel Xeon E5-2690 @ 2.90GHz 16629 ---> 32246 in dual CPU config
Intel Core i7-3960X @ 3.30GHz 14078
Intel Xeon E3-1275 V2 @ 3.50GHz 10572
Intel Xeon X5690 @ 3.47GHz 10413
Intel Core i7-3770K @ 3.50GHz 10376
Intel Core i7-2600K @ 3.40GHz 9077
Intel Core i5-3570K @ 3.40GHz 7722

But Xeon cost a lot, so for a non professionnal use (24/7 rendering) then a I7 is ok...(E5-2690 cost 1500$)
Also you can't really overclock a Xeon cause, as i know, they have locked multiplier and a I7-3960x @ 4.5-5ghz will become as fast as the xeon but have instructions to run games too...

Thanks for your detailed reply.

I think I will get a i7 in the future, and maybe Xeons with dual cpu config. in the far future, when I have much more money.

Thanks again dude.
