DivX 8.5.3 with Xmpeg 5.0.3
Our DivX test is the same DivX / XMpeg 5.03 test we've run for the past few years now, the 1080p source file is encoded using the unconstrained DivX profile, quality/performance is set balanced at 5 and enhanced multithreading is enabled:
Lynnfield inches towards the crown with the 860; it's closer to the 870 than the Core i5 750, and that's to be expected. The biggest gains here are due to Hyper Threading, the clock speed is just icing on the cake.
x264 HD Video Encoding Performance
Graysky's x264 HD test uses the publicly available x264 codec (open source implementation of H.264) to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
The Core i7 860 continues to do better than the i7 920, even if by only a small margin. As expected, it's closer to the 870 than it is to the i5 750 thanks to Hyper Threading.
Windows Media Encoder 9 x64 Advanced Profile
In order to be codec agnostic we've got a Windows Media Encoder benchmark looking at the same sort of thing we've been doing in the DivX and x264 tests, but using WME instead.
The race is close here, there's only a 2 second difference between the Core i7 870 and the Core i5 750. The 860 lands closer to the 750 this time.

Well, it will defiantly sell well in terms of OEM market. Since they will sell the same amount of PC, and Intel will be pushing Lynfield into their throat anyway.I wont even called that Sales, it is more like tax on those OEM makers.
I think it wont sell well in terms of Retail market.

Ivy Bridge is a shrink of Sandy Bridge to 22nm. It's Haswell that will have FMA.iwodo - Sunday, September 20, 2009 - link
Yes. It is Ivy Beidge ( the shrink of Sandy Bridge ) for FMA.It was supposed to be for Sandy Bridge, but some changes delay it to Ivy Bridge. So unless they have postponed it AGAIN. it should be out with Ivy Bridge.

I know the basic archetecture of Lynnfield is superior to Bloomfield, but you are not using 6gb of tri-channel memory for the i920. That is where the i920 really shines. Is there a reason that you are not testing with 6gb of ram with the 920 other than apples to apples testing that needs to be done? Just curious.the zorro - Saturday, September 19, 2009 - link
lynnfield has another gigantic bottleneck which is the dmi bus speed of only 2GBps, phenom 2 hypertransport speed is 41.6 GB/s which means that is 20 times faster than lynnfield when communicating with the chipset,that shows why phenom 2 is better than lynnfield. this is going to be a real problem in the next future.silverblue - Saturday, September 19, 2009 - link
Actually, as HT 3.0 is limited to 16-bit width on AMD desktop boards, it's half that.DigitalFreak - Saturday, September 19, 2009 - link
Next future? As opposed to the current future? I must thank you for all the laughs I get from reading your posts.TA152H - Saturday, September 19, 2009 - link
No offense, but you're clearly an idiot.You realize that in EVERY benchmark, the i7 860 was running at higher clock speeds than the i7 920. Sometimes by a lot, with turbo mode. Also, Anand uses inferior memory for the i7 920, to try to 'prove' the validity of the brain-damaged P55 platform.
Despite his bad attempt, the i7 920 STILL outperformed it. If you clock them at the same rate, with the same uncore, it's only ugly for the Lynnfield.
It's not superior. Well, in performance. It's got nice power characteristics, and it's cheaper to implement. But, your remark is purely idiotic.
Where do you get stuff like this from?

Lynnfields are categorizes as mainstream, therefore no matter how advanced their architecture is compared to Bloomfield, it won't out perform it. Intel purposely did this and you should know this by now, but I guess you don't care as your too busy sucking your own c0ck."Your the kind of man that can be use as a blueprint to build a idiot".

Sorry. I didn't mean to say anything that would warrant an "idiot" label. I have just been reading from Anand that the Lynnfield core is better than the Bloomfield. In all his testing he never uses 6gb of ram in his tests. I understand that he wants to measure the cpus on a level playing field, but when you put 6gb of pc1600 ram on an i920 those scores increase considerably. From what I understand that is something that the Lynnfield cannot achieve. Was just wondering if Anand could throw that (i920 w/6gb) into his charts. It seems that almost all Bloomfield owners are gonna be running 6gb (3x 2gb) and not 4gb. The i920 uses that extra bandwidth and it truly performs better when so equipped. I hope that makes more sense.
