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.

Great Article Anand, I read it with great interest.However I found somthing that was strange and unexpected today
My I7-860 was running at 30x133 3990 when running nucleus, that's according to cPU-z I have a link , but can't post http in this comment ?

I'd appreciate your insight ?
thanks

You need to change your version of CPU-Z. I have a screenshot somewhere around here of 48x133. ;)Scali - Thursday, September 10, 2009 - link
On a slightly related note... With these new P55 boards I see that especially Asus uses a new line of onboard audio chips from VIA.I haven't really been able to find much info on these chips. I'd like to know how they compare to Realtek and other onboard offerings.
Could you guys spend some time on reviewing the onboard audio next time you review one of these boards? Eg, what does the control panel for these chips look like, what features does it have (eg, can you have realtime encoding like DTS connect or DD Live?), what is the general driver quality like (proper support of 3d/eax effects etc)?
I think that's what's been missing in general, the past few years. Onboard audio has gotten quite advanced, to the point where most people no longer use a separate soundcard (some boards actually come with some sort of X-Fi card). However, I rarely see onboard audio reviewed, only audio cards.

for me, i find this review is misleading if you are not a gamer - for i5-750 and PII x4 965.why?
1. motherboard and video card - non-gamer dont buy sli/xfire board. onboard graphics is fine(780g/785g). for now, boards for i5 setup doesn't have onboard graphics. what will you do? you will be forced to buy a video card (maybe 4550/9400gt for $40).
i5-750 - $195, GIGABYTE GA-P55M-UD4 - $150, nvidi 9400gt - $40
--- TOTAL -------- $385
PII x4 965 - $245, GIGABYTE GA-MA785GMT-UD2H - $90, no video card
--- TOTAL -------- $335
AMD setup is actually cheaper but slower. it's all up to you.
2. power consumption - since you are forced to buy video card, it will consume additional power while AMD setup (780/785G) won't.
well that's just my opinion.
please inform me and the others if i given up wrong informatin

Or you can get a motherboard that's quite a bit cheaper:MSI P55-CD53
http://www.newegg.com/Product/Product.aspx?Item=N8...">http://www.newegg.com/Product/Product.aspx?Item=N8...
which is 120..
or
GIGABYTE GA-P55M-UD2
http://www.newegg.com/Product/Product.aspx?Item=N8...">http://www.newegg.com/Product/Product.aspx?Item=N8...
And yes I know these are NE prices, and that it might be more expensive/cheaper somewhere else

It DOES NOT have hyperthreading. Enabling it wouldn't increase the cost of the chip, it purely a political move. I HATE that! If a CPU maker has something that can increase the performance of my cpu, at no cost to them, then should enable it, at no cost to me. EVERY CPU should have unlocked multipliers. EVERY CPU should have hyperthreading.jnr0077 - Friday, July 27, 2012 - link
hyperthreading steal ram from your pc i have a i5 750 + radeon hd 4850 it plays crysis 2 maxed the witcher 2 maxed skyrim maxed i think you need to read up on it before you comment :)PhilTaylor - Wednesday, September 9, 2009 - link
FSX is well known as a CPU-limited game, it might be more interesting to test it then a GPU limited game like Crysis. For instance, the difference between 2 and 3 memory channels might have a greater impact on FSX, again due to its CPU-limited nature.cactusdog - Wednesday, September 9, 2009 - link
A very good, detailed bunch of tests but there is a surprising lack of information regarding temps? Other review sites have done the same thing but there IS temp issues with these CPUs as with i7 1366 ones. That CPU at 4.0 Ghz on air will be around 90 degrees but little is said.Anandtech is more honest than most review sites (most of which are really just advertisements) but sometimes i get the impression that nobody wants to upset Intel.

...bottom line to me, my E8500/crossfire setup still has plenty of gaming life left. I'll check back in a year.
