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

Microsoft Excel 2007
Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.
The Excel test is peculiar in its results. It must be one of the few situations where Bloomfield's memory bandwidth advantage is seen as even the Core i7 870 can't outperform the i7 920. The Core 2 Quad Q9650 does well thanks to its large 12MB L2 cache, as does the Q6600 with a beefy 8MB cache.
Sony Vegas Pro 8: Blu-ray Disc Creation
Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spend encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.
Hyper Threading is good for about 4% here, giving the 920 the slight edge over the Core i5 750.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
The i5 750 pays the HT penalty, taking another 20 seconds to render our test video than the i7 920. It is still faster than the Phenom II X4 965 BE at a much lower cost. The Core i7 870 comes close but can't beat the i7 975.

You definitely ARE stupid.dragunover - Tuesday, September 8, 2009 - link
Readers aren't, but you didn't read...snakeoil - 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)
