Yep. I concur and here is a little testing I did while reading your article:
CPU CPU Clock Motherboard Chipset Memory CL-RCD-RP-RAS Score
4x Core i7 920 HT 3800 MHz Gigabyte GA-X58A-UD5 v2 X58 Triple DDR3-1448 8-8-8-24 CR2
This is a Bloomfield chip.

Passmark 7
CPU Mark: 7884
Memory Mark: 3263
Street Fighter IV: 8934
x264
AVI: 84
MP4: 34

And note that although the 975BE @ 4Ghz comes close to the stock 920 in Queen, it's still about 6% slower and in Photoworxx a full 30%+ slower. That at 4Ghz the best of AMD can only muster what a now lowly 920 can do at 2.66Ghz is pretty sad.

# SAD You say??Toeringsandthong 2011-02-03 04:42
Hers some food for thought ! whats sad is paying alot more for 920 when you dont have too ! think about it fanboy !

pretty much this CPU has been put out there for us AM2+ users who don't want to OC or don't want x6 10xx CPU's but would like a little more power.... I can't see why any serious upgrader would buy this right before the release of bulldozer based CPU's

Oh and I cant believe that my #ty old PII x4 940BE @ 3.4GHz beat out the x4 840 in every test in AIDA64

# It should beat the 840Hank 2011-01-05 07:35
The X4-840 isn't really a Phenom-II Chip, it's an Athlon-II with the name Phenom-II. The 840 doesn't have any L3 cache and is built on a Propus die. Also, at $102, its a lot cheaper than any of the Phenom-II X4 processors. That your X4-940BE beats it isn't all that surprising.

Feel free to read my review of the Phenom-II X4-840 as well -- #benchmarkreviews.com/index.php?option=com_content&task=view&id=662&Itemid=63

I'm very sorry to read this article and still the author is so bent on Intel that he passes the fact that the new Intel chip can't even run on Linux.AMD still does.You so called Intel superchip is'n't that far in front of the 975BE.Only in the encryption it's got some advantages thanks to a lot of compiler tricks.But in plain battlefield Intel sucks big time.Even in the game it loses to an old phenom 2 architecture.Don't teint the truth by using words. Intel sucks!!!!!!!AMD rules!!!!!

# Read the articleHank 2011-01-05 07:37
If you would have read the article, you would see that I said I preferred the Phenom-II X4-975BE as a gaming CPU over the i5-2500K. Also, the margins were anywhere from 8% to 35% without counting the AES test. I also stated that prior to the Sandy Bridge release, I preferred the ATHLON-II series over the i5 chips. Read the article next time, not just the last page.

# 975 BE for now, Bulldozer later...nt300 2011-01-05 07:50
There's no bias within this article as some of you may think. Anyway great review and a very good upgrade path for people wanting to stick to the AM2+ and AM3 platforms. I am waiting for Bulldozer, though I would get this chip just to buy me some time in between, but it has to be dirt cheap $$$...

I believe the 975 AMD processor is excellent, I would buy one but can not find the motherboard for this processor. Unfortunately, there is the motherboard for this processor on the market.

You can use any AM3 motherboard for this processor. There are many models available.

Really you'd spend the extra over an x4 965 or an 955 for that matter

965 + 300MHz OC = stock 975BE and it's the same deneb die you only going to get out of a 975BE what would be attainable from an 965 + a descent cooler
