Official AMD Barcelona Thread

[Shintai]

What PDF?Those are for Barcelona (with reg ram) and in SPecRate...You yourself were bashing those as unreliable for performance comparisons.So you don't know for sure what IPC gain will K10 have over K8 in int and fp workloads.Just get over it and look forward.

Powerpoint, not PDF.

If you whine and complain, then atleast do abit of tiny research first. Instead of just cry and nag over we dont agree with you that K10 is the new wonder of the world.

Reread the edited post man.

And it seems you really want K10 to be a prescott(in your words).Whats up with that?Guessing and trolling about how "sucky" it will be is not a way to participate in news thread.

[BrowncoatGR]

No, this:

Notice the "projected" part? Also these are server chips without HT3 running slower memory and spec is by no means representative of desktop performance. A lot of work for K10 went into SSE improvements. It should be up to almost 100% faster than K8 at SSE calculations. I'm hope AMD will release more info at their Conference Call in a few weeks

[informal]

Since Shintai likes to think he knows IPC advantage K10 has over K8,let's see what Randy Allen had to say in ZDnet interview some months ago:

Quotes:

From the 1st page:

"We expect across a wide variety of workloads for Barcelona to outperform Clovertown by 40 percent," Allen said. The quad-core chip also will outperform AMD's current dual-core Opterons on "floating point" mathematical calculations by a factor of 3.6 at the same clock rate, he said.

Barcelona employs several features to improve performance, Allen said. Among them:

• It's AMD's first chip with a built-in level-three cache. Cache memory can respond faster than main memory, and Intel has relied on large amounts of cache to improve its processors' performance. Each Barcelona core has its own 64-kilobyte first-level data cache, 64KB first-level instruction cache and 512KB second-level cache; and the four cores together share a 2MB third-level cache, though AMD has said that size can be increased.

• AMD redesigned the Barcelona core, marking the biggest changes since the company made its 2003 transition from its 32-bit Athlon chips to the current 64-bit lineup. The magnitude of the transition is about halfway between the small tweaks AMD has made to Opteron over the years and the clean-sheet redesign Intel employed in moving from NetBurst to its current Core design, Allen said.

• A faster floating-point engine performs mathematical calculations--long an Opteron strong suit, though not as important a part of the chip as that for integer operations. At a given clock frequency, a Barcelona core outperforms a current Opteron core by a factor of 1.8. By going quad-core, a Barcelona chip overall will provide a boost factor of 3.6, Allen said.

Is Randy not telling the truth here about FP improvement?So he tells per core K10 is 80% faster clock for clock,3.6x faster considering all four cores.

You are amazing. In that case, I will like to say than penryn, in certain mathematical extensive applications(divx) is up to 110% faster than Conroe. Or a factor of 2.2 from core to core! And what he refers to is only SSE loads. Also telling us the singlecycle SSE didnt give them a 100% increase in SSE loads, but "only" 80%. Core 2 got a factor 4-6x over Core in that area. Didn´t lead to any miracles.

PR Spins FTW!

Anyway, now you are talking about Randy. Lets see what has changed since that statement some months ago.

http://www.channelregister.co.uk/200...arcelona_2ghz/

"We will be seeing a performance boost of 40-50 per cent above our highest frequency dual-core products that are available today," AMD VP Randy Allen told us.

Funny eh? Where did the factor 3.6 go? 40-50% Over a dualcore 3Ghz. So a 2Ghz quadcore performs like a 4.2-4.5 K8 dualcore. I guess reality caught up again!

Thank you Informal



Its good to see a possible 80% increase for each core

[informal]

Well Shintai seems to be testing these K10s ,so we can ask him up about the impressions,numbers,hard facts.Seems he even knows better than Mr. Allen.

[nemrod]

Shintai, why not wait barcelona availibity. You will not be able to convince those guys before.

[BrowncoatGR]

Shintai you are really taking that article seriously? Anyway K10 has double the SSE throughput of K8. What are we even discussing here?

[nemrod]

Well Shintai seems to be testing these K10s ,so we can ask him up about the impressions,numbers,hard facts.Seems he even knows better than Mr. Allen.

You chose beetwen what Allen has said, you don't care about what allen said June 29 2007 but you keep old allen mistakes? But probably, you've tested K10, and you even better know what is true beetwen allen x 3,6 and allen 40-50% better...

[informal]

You chose beetwen what Allen has said, you don't care about what allen said June 29 2007 but you keep old allen mistakes?

"Old Allen mistakes?"
Are you serious man? The guy who was behind K9(dual core K8) has made such a dumb mistake?Wow,just wow.

The June quote was probably the reference to low clocked 2 Ghz part(and we don't know what that number really represents,do we?)

[nemrod]

"Old Allen mistakes?"
Are you serious man? The guy who was behind K9(dual core K8) has made such a dumb mistake?Wow,just wow.

Yes wow, just wow if not him the writer of the paper has not understand and fail to tell what Allen said.

[informal]

Yes wow, just wow if not him the writer of the paper has not understand and fail to tell what Allen said.

That is a transcript man.Transcript.And the per core reference has been repeated by Allen a couple of times.Still not clear?

[EternityZX9]

Jesus, could the mods here do something about this thread crapping?...what was once a nice thread has turned into a flame fest...

[nemrod]

could you read that february

Optimum Performance Levels
While special attention was paid to the power-saving design features in native Quad-Core AMD Opteron processors, equal emphasis was placed on delivering industry-leading performance. Quad-Core AMD Opteron processors are packed with core and cache enhancements designed to improve performance on a range of server and workstation applications. Cache-sensitive transactional applications such as Web, database and email servers can benefit from the addition of a 2MB shared L3 cache. Simulations conducted in AMD laboratories indicate that certain database applications will see performance improvements up to 70 percent and certain floating point applications will experience performance gains of up to 40 percent over platforms powered by current dual-core AMD Opteron processors. High-performance computing (HPC) applications can benefit tremendously from a doubling of Barcelona’s floating-point execution pipeline to 128-bit width, which includes an AMD-only doubling of instruction and data delivery capabilities. Finally, through enhancements to AMD Virtualization™ (AMD-V™), including Nested Paging, virtualization customers can enjoy additional application performance improvements over non AMD-V driven applications.

With planned availability at launch in a range of frequencies up to 2.0 Ghz, AMD expects its native quad-core processors to scale to higher frequencies in Q407 in both standard and SE (Special Edition) versions. Designed to operate within the same thermal envelopes as current generation AMD Opteron processors, AMD estimates that the new processors can provide a performance increase up to 70 percent on certain database applications and up to 40 percent on certain floating point applications, with subsequent higher frequency processors expected to significantly add to this performance advantage.

“More than ever before, customers are expecting energy-efficiency and performance-per-watt leadership as much as absolute performance. With this new reality of computing, greater performance at the expense of greater power consumption is no longer an option,” said Randy Allen, corporate vice president, Server and Workstation Division at AMD. “AMD has prioritized production of our low power and standard power products because our customers and ecosystem demand it, and we firmly believe that the introduction of our native Quad-Core AMD Opteron processor will deliver on the promise of the highest levels of performance-per-watt the industry has ever seen.”

nemrod,both articles are mentioning the average per. figures(ie 2GHz K10 Vs the current K8s).
Those ZDnet quotes are especially for FP/SSE code!

Their talking about a 70% increase with the exact same power consumption.
I would say that is very Good

Shintai, why not wait barcelona availibity. You will not be able to convince those guys before.

That should apply to you also

[nemrod]

not agree "up to" is not average. But it doesn't matter we will see that in a month or two and I'd like to be wrong.

Their talking about a 70% increase with the exact same power consumption.

yes they put 2x more cores with the same power consumption. but as said we will see later

[informal]

Well nobody knows for sure until K10 finally lands in reviewers hands.

It's incredible how lame Theinq can be : http://theinquirer.net/default.aspx?article=40749

1.In the Spec tests they compare the estimated perf of a 2.6GHz K10 vs. 2.66 Clovertown

2."Recently, we managed to sse the short of performance figures that AMD is promising for Barcelona."

Too bad the first 2 slides are form december 06 and the last 2 from february 07.

[red]

But in the Integer test, a Barcelona 2.3GHz yields 21% higher score than Clovertown 2.66 GHz, but Floating Point test leaves a staggering 50% performance deficit for Clovertown

It's 2.6GHz, clear as day on the footnotes

and this is not something 45 nanometre Penryn can solve overnight

http://www.spec.org/cpu2006/results/...528-01175.html

106 vs 102, 106 wins. On 65nm.

Wait a minute...
I see this:

These performance numbers were based on systems using tge Opteron 2356, or known to the world of us regular folk as AMD QuadCore at 2.3GHz

and this:

Barcelona 2.3GHz yields 21% higher score than Clovertown 2.66 GHz

Where do you see 2.6GHz K10?

And where are the slides?

[Shintai]

Look on the picture. They estimated the performance at 2.6Ghz for barcelona. And gotta love memory intensive synthetic benches. (Last line on the text on the picture)

[SEA]

I probably need to wear eyeglasses from now on...
I don't see any picture there on inquirer!

Can you please explain why you link AMD slides with link to inquirer? I might miss something...
