Woodcrest will be 10-20% slower than Opteron 280

In October 2005, INTEL announced the Paxville Xeon processors, INTEL claimed a 50% performance increase. That has become a subject of ridicule in the industry, as it had only half the speed of Opterons and INTEL refused to benchmark them.

It's Spring IDF time again, and INTEL sales are plummeting, so again, INTEL promised by 3Q of 2006, we will get a new server chip called Woodcrest on the Bensley platform. INTEL reckoned that Woodcrest will be 80% faster than the Paxville DP 2.8GHZ, it will also get rid of the useless hyperthreading stuff invented by INTEL America.

Wow! 80% on top of 50%, impressive!

So let's check some existing benchmarks for the referenced Paxville DP 2.8GHZ and see how this Woodcrest wonder chip will do for us in 3Q06. The Paxville DP 2.8GHZ and Opteron 280 results are here.

First, let's look at web server performance:

For 10,000 users, the Paxville handles 701.7 HTTP request/second, not bad, times a factor of 1.8, we get 1263.06 res/sec for Woodcrest, impressive for INTEL. Opteron 280 does 1505.8 reqs/sec, Opteron 280 is only 19.2% faster than Woodcrest.

Next, let's look at media encoding, this benchmark might be relevant for workstation users:

Windows Media Encoder 9.0: Paxville 2.8GHZ finished in 100 seconds, quite fast, devide that by 1.8 for Woodcrest estimate, we get 55.55 seconds; Opteron 280 does it in 51 seconds, Opteron 280 is only 8.9% faster than Woodcrest.

Next, let's look at Scientific stuff, scientists need computing power too:

Sciencemark 2.0 - Primordia: Paxville 2.8GHZ finished in 584.3 seconds, divide that by 1.8, we get 324.6 seconds; Opteron 280 does it in 290 seconds, Opteron 280 is merely 12% faster than Woodcrest.

During the IDF, HP had to use a HP DL380 armed with a 3GHZ Woodcrest to pit against a 2.4GHZ Opteron.

AMD just shipped Opteron 285 a couple of days ago, you can get it FedExed to you in 1-2 days, it plugs in nicely onto current Socket 940 boards.

In conclusion, AMD's Opteron 280 only has a 10-20% performance advantage over Woodcrest, we don't have scores for Opteron 285 yet, it's too new, maybe AMD will do better by 3Q06 when Woodcrest comes out to take a frag.

CorvetteKid Says: Sharikou, assuming the 80% boost and that your linear computation of speed is correct, the gap between Opteron 280 and the forthcoming Intel chips narrows, no?

So the question becomes: what does the 285 do vs. the 280? I would guess it has to outperform the 280 by at least 20% to give it close to a 30% advantage that is noticeable and marketable for AMD vs. Intel.

If AMD chips are 10% or less better than Intel's for the same $$$, then Intel can claim "victory." Let's hope we maintain a significant advantage.

And I want to see Ruiz and AMD be more aggressive on laptops. I know servers are where the $$$ are, but laptops are where the word-of-mouth among retail is (plus desktops, as my relative just bought a $1,800 AMD setup).

Would you please stop referencing that false benchmark article from GamePC? Most people know they got wrong results. Did AMD fund your Ph.D. study or what? You are diminishing Intel's new server by simply doing a pre-school calculation. Even after 6 months all your calculation is proved right, don't forget we care more about performance per watt now. Woodcrest consumes much less power than P4. And the price is also another significant factor.

GamePC did a very valid set of benchmarks which matched other benchmarks quite well. I noticed that DELL requires customers to sign NDAs before buying Paxville, so right now, the GamePC benchmark is the most complete one can find. If you accuse their benchmark to be false, report to INTEL. Go to and see more benchmarks.

On power consumption, Paxville is 170 watts, Woodcrest is 40% less, so it will be about 100 watts. Opteron is at 95 watt, 68 watt or 55 watt

Oh, someone else don't know their pre-school math.

Sharikou, is it worthwhile to buy an AMD Turion laptop right now? Or wait until AM2?

Sharikou, U are wrong. Woodcrest is only 80 watts not 100 watts

I bought a Turion laptop lately. For me, it is 64-bit and fast enough for almost anything. The performance bottleneck of my laptop is more on the Disk I/O.

My guess is : it does not matter much whether AM2 or not.

HP did a comparable testing of a 3GHZ Woodcrest against a 2.4GHZ Opteron during the IDF running 32 bit Windows. Opteron should get a 30% boost running Windows x64.

I'm compelled to ask how on Earth you got a Ph.D. You should probably take a picture of that and host it on your blog, as most people with half a grain of common sense would probably take your "benchmarks" with about half a grain of salt.

You're likely the type who, when direct Woodcrest vs. Opteron benchmarks come out, will deny them on the basis of Intel strong-arming or something of equally ridiculous and unfounded nature.

Independent test, FX60 does 214.4 FPS in UT2004

INTEL's IDF setup, Conroe does 189.3 fps at the same setting

Where is the benchmark of conroe on I cannot find it.

BTW, anybody got a woodcrest benchmark? It's coming out soon but yet classified.

Maybe y'all didn't know your core architectures but Woodcrest is not based on the Conroe core. Conroe is revised Netburst Core (p4) whereas Woodcrest

Thus Woodcrest operating on another core of its own is possible to get beaten by an Opteron.

This shows that the woodcrest beats Rev F opteron but not by as much as intel claims:

I guess he got his Ph.D. from a Canadian university, where anyone can get Ph.D if he stay for seven years and give the incapable and immoral so called "professor" some money. You give Canadian university money, they give you diploma in return. And anyone who work in a Canadian university for more than twenty years can becaome a so called "professor".

Canadians are very incapable and the so called "professor" are jealous of those who have sheer ability.

There is no difference between Canadian Ph.D and a European high school diploma and there is no difference between a Canadian university professor and a kinggardon teacher. Canadian professors and their money-bought Ph.D. are all trolls.

Many people who cannot get into to a university in their own country go to Canada, a place full of the incapable, cheaters, liars and trolls, full of poor quality people, because you give them money, they give you degree. Canada is world's trash can, full of every country's rubbish.

Canada does not have democracy and freedom, nor does it know the defination of liberty. Over the years, the government becomes very corrupt and tyrannic. People are under the incapable's brutal oppression.

Such poor country should be overthrown and we should established a new demacratic free society there and drive the incapable, cheaters, liars and trolls back to their own country.
