AMD "Barcelona": clocks

Conclusions

Barcelona is the first revision to AMD’s microarchitecture since 2003. Rather than starting from scratch, Barcelona builds on the previous generation and subtly improves almost every aspect of the design. In many ways, this mirrors the evolution of computer architecture – there are very few techniques that can give a large boost on a wide spectrum of applications. Instead, architects are turning to many smaller improvements, just as AMD has done with Barcelona. The only obvious trick left in the bag for AMD is multithreading, which could provide a big boost in a future microarchitecture, such as the K10. However, this style of conservative, consistent design has worked very well for AMD in the past.

Barcelona is a solid improvement across the board and should give AMD momentum across several key markets. The performance advantages will be decisive for HPC applications and MP servers, other areas will be close in performance. Hence, there is quite a bit to look forward to in the near future with the debut and performance numbers for Barcelona. No matter what, AMD's engineering teams deserve kudos for a solidly executed product.

Aki está um óptimo artigo, bastante ( até demasiado para alguns :P ) técnico sobre o Barcelona comparando-o com o antigo K8 e o core 2

As alterações n são subtis e cada unidade foi refinada de modo a aumentar o IPC.

O Quad core nativo, a cache L3, melhoria de prefetch, Out-of-Order Engines, aceleração de instruções SSE e o alargamento de vários buffer são apenas algumas das novidades.

A grande vantagem será no mercado dos servidores devido à maior largura de banda entre os varios CPU.

Nos desktop tb haverá um incremento significativo da performance, graças a um maior ICP e um controlador de memoria renovado.
Tb implementa melhoramentos no campo do da redução de consumo, assim como um melhor controlo da temperatura, voltagens e frequências dos vários CPU's.

Claro k n é só arquitectura e as frequência k a AMD vai conseguir espremer do seu processo de fabrico serão cruciais para o sucesso do barcelona.

Já n falta mt para ver no k se traduzem estes melhoramentos na arquitectura. :)
 
acho que todos nos aqui ja so acreditamos na AMD vendo! VER PARA CRER!

depois dos barretes das graficas nao me admiraria de que isto fosse outro flop!


aguardo pacientemente resultados VISIVEIS e BONS! core 2 está ca ha quase um ano :D domina a 100%! :D G80 está ca ha 6 meses, domina e continuara a dominar! sem concorrencia o mercado fica caro e os price drops nao acontecem!

Não acredito num flop, até porque a arquitectura actual K8 é boa e não "envergonha", embora não o suficiente para a concorrência actual C2D.

Eu acredito que o K10 será competitivo, agora até que ponto não sabemos e não arrisco previsão. Deverá ser bom, mas o que poderá por em causa a competitividade do K10 não será a sua arquitectura, mas antes a evolução do seu rival.. Intel 0.45nm.

Computex 07: Opteron 2200 Up and running

We finally had the chance to see Barcelona K10, Opteron 2200 series in action. We saw two machines both up and running and we have quite a few nice screenshots. One of the two had two processors or eight cores.

The one server model we’ve seen works at 1.61 GHz and get recognised as AMD processor model unknown but you can clearly see the four cores. So there you go you malicious Swedish boys and there will be more of these.

Speaking of AMD, we were originally hoping as many others that Computex 2007 would have been the launch event for Barcelona and Agena. Unfortunately, this will not occur and the best we can hope for at this time is a Barcelona release in the latter part of Q3 at best and Agena following up in late Q4 or possibly sliding to Q1 2008 based on recently received information. The motherboards and chipsets to support this new processor family are starting to take shape but they are far from optimized at this point with early production level silicon just now being made available for the various suppliers who will offer products at launch. Our first look at the RD790 chipset from AMD that supports the new AM2+ socket, HyperTransport 3.0, and DDR2-1066 was interesting to say the least but it is too early to tell what the true performance potential of this technology is until we are able to test it with final silicon.

In fact, although we have seen DVT level chips running up to 2.3GHz, we understand there might be another silicon spin (maybe more) of Barcelona that is due later this month. If this occurs, then current rumors swirling around the trade show floor about the mass availablity of product not occuring until the fourth quarter might just be true. At this time the motherboard/chipset companies are in the process of locking down their designs and optimization of the BIOS for performance is just starting. Our early first looks at application benchmarks show a great deal promise for this processor series but nothing overwhelming or very exciting at this point in the game. We, as others, are hoping for some serious competition from AMD as this is good for the market whether you are an Intel or AMD fan. Let's just hope the Barcelona/Agena series performance comes up to speed quickly (along with supply) or AMD is going to be in real trouble heading into the critical Q3/Q4 buying season.

Estou a ver que K10 nos desktops em verdadeiro volume (QuadFX/Quad-cores não são "volume" nos desktops aínda) só lá para 2008, tal como eu disse aqui há meses...

Mas isso ja se sabia há muito tempo. Em 2007 so vão vender 1 milhao de K10. Que é poucoxinho....
No entanto quando a nova fabrica tiver a full-power devem produzir CPU´s que é uma coisa parva comparativamente ao que podiam produzir no passado (waffers maiores + 65nm).

E yields menores, visto que o processo 65nm está com problemas desde há seis meses (as versões com mais capacidade de OC escolhidas para as versões de topo, são todas 90nm).

P.S.:
A nova fábrica (FAB 36) pode vir a estar a "full-power" daqui a 6 meses, mas a antiga (FAB 30) vai ser progressivamente desactivada para sofrer upgrades (passa a chamar-se FAB 38).

No fundo, nada muda. A AMD vai continuar a tirar produto das lojas para vender a OEM's, pois sabe que no mercado retail a sua imagem é muito fraca neste momento.
 
Mas é que eu estava a pensar actualizar sito CPU+board+mem, e assim ja sabia para me onde virar, se para Intel ou AMD...

Pode ser que estes K10 nos dê umas luzinhas sobre os futuros Phenom :004:
 
Barcelona "on time", but Budapest slips

Citigroup analyst Glen Yeung has begun suspecting that Advanced Micro Devices' quad-core "Barcelona" processor is late, but the chipmaker said Tuesday that it remains on schedule. However, shipments to supercomputer maker Cray of a close Barcelona relative code-named Budapest have slipped.

There is "no delay" for Barcelona, spokesman Phil Hughes said Tuesday. The chips, and some systems using the chips, will be available in the third quarter, he said.

Barcelona is a strategically important chip for AMD, as it tries to regain market share lost to Intel's newer Core 2-based Xeon server processors, the dual-core 5100 and the quad-core 5300.

However, Budapest shipments to Cray slipped. "Specific to Cray, we did have a change in our schedule, as far as when Cray gets Budapest parts," Hughes said, declining to share further specifics.

Barcelona is designed for systems with two or more processor sockets, but Budapest is for single-socket systems.

Cray in May said it delayed an upgrade to its AMD-based XT4 supercomputer until "late 2007."

AMD Partners Demonstrate "Barcelona" at 1.6 GHz

Quad-Core AMD Opteron demonstrated by MSI, Supermicro, TYAN and Uniwide

AMD took the opportunity at Computex to server platforms running the Quad-Core AMD Opteron processors, codenamed Barcelona, with the help of MSI, Supermicro, TYAN and Uniwide

The AMD quad-core processors are designed to drop-in (following a BIOS upgrade) with all existing AMD Opteron processor-based systems using DDR2 memory, while also enabling new platform capabilities such as those being demonstrated today.

One vendor demonstrated Barcelona to DailyTech running at 1.6GHz. Current AMD Barcelona samples are not scaling too well. AMD partners confirmed the highest running, POST and OS capable, Barcelona processor is 2.0 GHz. AMD previously posted benchmarks of a simulated 2.6 GHz Barcelona.

“We commend AMD for its non-disruptive roadmaps, allowing for a smooth upgrade from dual-core to quad-core,” said Danny Hsu, president, TYAN. “Streamlining and mitigating the complexities customers often face when upgrading their IT infrastructure is especially important in today’s competitive marketplace. TYAN has collaborated with AMD since 2001, and we will continue to support and take advantage of the customer-centric innovation AMD is offering in its quad-core processors when they are made available later this year.”

AMD roadmaps show Barcelona-based Opteron processors will launch in July, but the general consensus from partners is the processor isn’t performing well enough for a July launch.

“Quad-core, codenamed Barcelona will launch later this summer, in the July, August kind of time frame -- followed by [consumer chips] on the desktop... You'll see that in the Christmas line-up,” stated Robert Rivet, AMD executive vice president and CFO, just a few months ago.

Quick and Dirty AMD K10 Cinebench
An early AMD "Barcelona" revision gets its first non-simulated benchmark

Earlier today, AMD announced that it successfully demonstrated Barcelona across the server market. The company did not publically state how fast the processor was running, the stepping of the processor, the processor thermal envelope or the eventual ship date.

We had the opportunity to benchmark the AMD Barcelona, native quad-core on an early stepping. We only had a few minutes to test the chip, but we were able to run a quick Cinebench before we were instructed to leave.

The AMD benchmark ran on a single-socket, K10 CPU running at 1.6 GHz on NVIDIA's nForce Professional 3400 chipset. According to the system properties, the AMD system used 4GB of DDR2-667.

The most similar Intel system we could muster up on such short notice was an Intel Xeon 3220. The Xeon X3220 is clocked at 2.4 GHz, and ran on Intel's Garlow workstation chipset (Intel X38). This system property profile stated the system utilized 4GB of DDR2-800.

Cinebench completed the default benchmark in 27 seconds for the 1.6 GHz K10; 17 seconds for the Intel Xeon X3220. The Kentsfield Xeon was 58% faster with a 50% higher clock frequency for Cinebench.

AMD partner engineers tell DailyTech the chip we tested was the latest revision silicon. The same engineers claim 2.0 GHz Barcelona chips are making the rounds, with 2.3 GHz already on the desktop and server roadmaps.

AMD's current guidance suggests a late July announcement for Barcelona. However, when DailyTech tracked down the individual partners named in AMD's press release, all cited "optimistic September" ship dates for motherboards.

Não me parece um bom arranque para o K10... Muito difícil vai ser a vida da AMD nos próximos tempos...
