The part I don't understand is why you took Intel's PR claims as some sort of gospel in the first place.

sorry meanwhile you posted I was editing my previous post:

"not only claims, but Intel IDF benches"

Do you remember the WOWS, WOOTS claims from guys here and there?

Cinebench overall Woodcrest 3.0ghz 15% faster than Opteron 2.6ghz
POV-Ray 4 threads Woodcrest 3.0ghz 6% faster than Opteron 2.6ghz
3DS Max overall Woodcrest 3.0ghz 21% faster than Opteron 2.6ghz
Windows Media Encoder Woodcrest 3.0ghz 5% faster than Opteron 2.6ghz
Xmpeg / DivX Woodcrest 3.0ghz 16% faster than Opteron 2.6ghz
Lame MT overall Woodcrest 3.0ghz 19% faster than Opteron 2.6ghz

This is about 15% overall faster (again Woodcrest 3.0ghz vs Opteron 2.6ghz)

(sintetic nonsense benches jumped)

btw 5% less power consumption at full load (it would be around 10% at same clock) isn't impressive either (specially 0.065 vs 0.090)
1) I always take the claims by the manufacturer with a teaspoon of salt.
2) 15% faster and 5% lower power is still significant. Even of AMD can up the performance by 10% and keep the power usage the same as now by July, Intel will still have the overall lead. I think that's quite an impressive turnaround for Intel, considering the comparatively poor performance/Watt ratio in their previous server chips.

again, considering Intel claims 20-40% faster at same clock speed.

What part you don't understand?

edit: And not only claims, but Intel IDF benches (remember?)

Tahts for single core.

Multi-core CPU's get degraded performance as it scales up in number. Happens with current Xeons, will happen with Woodcrest, and it even happens *gasp* to Opterons.

15% faster in quite impressive for 4P configuration when you think Intel is still using the DIB method. And this is on Alpha hardware with slow FB-DIMMs (not to mention the Opteron system has 2GB memory vs 1GB for the Woodcrest).

The IDF benches were Conroe and not Woodcrest... so I don't see why you're bringing up those tests. They are completely different platforms.

Well, I guess I prefer to look at actual benchmarks done by independent sites.

I'm just impressed that Woodcrest is performing so well, and at a lower power usage too. If you ignore previous hype and just look at the numbers, Intel is doing very well.

Woodcrest is conroe, like conroe is merom or merom is woodcrest, like A64 is Opteron, Turion is A64 and go on

Sure, the architecture is basically the same, but the platforms are very different. (Hence the different memory, core logic, etc...) Those aspects of the platform as a whole can have a tangible performance impact, especially when comparing desktop platforms and server platforms. Server platforms typically have lower overall performance because of the required error checking, stringent validation, etc...

This is not a single processor test. THERE ARE TWO PROCESSORS AND 4 CORES. SLOW RAM. AND a established opty platform that has the multiple processor platform about as effecient as you can get it.

533 MHz FBD...there's a HUGE difference!
From Intel's sheet on FBDimms Link

"1. Provides over 3 times higher memory throughput? allowing for superior application responsiveness
2. Enables increased capacity and speed to balance capabilities of dual core processors
3. Allows for Intel® I/O Acceleration Technology to more quickly access and process data
4. Performs reads and writes simultaneously; eliminating the previous read to write blocking latency"

BTW...thanks for the math. That helps!

Yep, it's amazing a brand new unreleased product/architecture can beat a mature ie three year old opteron core :disgust:.

I'm glad to see competition come back to cpu/server platforms, but this hysteria about a brand new architecture being 10-20% faster in some benches is kind of silly. Next spring, I think AMD will give a pretty good response with their K8L revamp followed by quad cores at the end of the year. Maybe by then, Intel will have CSI going so we can see nice competition from 1 to 8 sockets.

Anyhow, I too would have liked to have seen some 3rd party webserver and database tests...

:beer: to competition, :thumbsdown: to over the top "spanked, killed, etc" comments

Worth pointing out that Woodcrest actually has a typical TDP of 65W... mentioned somewhere on L'Inq, the yields were that good.

Seconded Trevor, though I don't know if they do any filtering of sites out here. Sharikou's blog = worthless.

A slight correction...the Woodcrest processors below 3 GHz are 65w TDP, the 3 GHz are 80w. However keep in mind that TDP is only a thermal guideline for building systems and NOT a guide as to power usage...

Yes, the AT tests don't really fall in line with the results from Techreport. Curiously enough, Woodcrest seems to suck at encryption.

I know my reply is a little late... Not sure whether you meant to insinuate that Tulsa is a "Core" uArch or not... but it's not ;) Tulsa is basically a Presler (Dual Core, old Netburst style) that was spliced together with a shared 16mb L3 cache :Q
