Intel's Core i7 870 & i5 750, Lynnfield: Harder, Better, Faster Stronger

Adobe Photoshop CS4 Performance
To measure performance under Photoshop CS4 we turn to the Retouch Artists’ Speed Test. The test does basic photo editing; there are a couple of color space conversions, many layer creations, color curve adjustment, image and canvas size adjustment, unsharp mask, and finally a gaussian blur performed on the entire image.
The whole process is timed and thanks to the use of Intel's X25-M SSD as our test bed hard drive, performance is far more predictable than back when we used to test on mechanical disks.
Time is reported in seconds and the lower numbers mean better performance. The test is multithreaded and can hit all four cores in a quad-core machine.
Hyper Threading does have a real benefit in Photoshop and thus we see the Core i5 750 suffering a bit. It's still faster than the Phenom II 965 BE but it is marginally slower than the i7 920. The 870 is bested only by the i7 975.

You definitely ARE stupid.dragunover - Tuesday, September 8, 2009 - link

wow, this lynnfield is expensive, and the motherboards are expensive too.this is a crippled core i7 and you will have problems because the northbrige only have 2 x 8 pcie express electrical.
so if you are going to buy a new directx 11 video card don't commit the mistake of buying a lynnfield which is crippled.
without hyperthreading in some cases is a 40% slower than core i7

Anand, can't you just ban this guy? He's always trolls against Intel here, TechReport, and a couple other tech sites.JonnyDough - Tuesday, September 8, 2009 - link
I second the notion.Chlorus - Tuesday, September 8, 2009 - link

Your comment will not affect people whose committed to bought these. I think it is more valuable than any AMD platform. I don't think AMD will survive next year.TA152H - Tuesday, September 8, 2009 - link
From a purely processor perspective, I'd agree, but AMD platforms are pretty strong when you compare IGPs. The G45 compared to the 790GX is worse comparison than the Phenom II compared to the Nehalem.Don't forget IGPs are a HUGE market, so it's not an unimportant consideration.

Yes, the IGP market is huge and Intel dominates that market as it is. If Intel can get its drivers right, then it looks like the IGP on Clarkdale/Arrandale will extend that domination. If you want to game seriously on graphics intensive games, then don't use an IGP.ash9 - Tuesday, September 8, 2009 - link
broaden your horizons; the real money is in corporate retooling- that said AMD's platform is without question offer more bang for the buck, considering corporate needs...most corporate folk have gone blind because of Intel's IPG's (laptops and desktops)Anand how bout running the tests that addresses that issue (IPG's and eye strain)
