Berkeley (CA) - Intel was first out of the gate with a quad-core processor, AMD will offer the first native quad-core chip - four processors that are integrated in one piece of silicon. The company today offered a first glimpse at a 4-way, quad-core Opteron processor system during its annual analyst conference.

There is little question that 2006 brought dramatic change for the microprocessor environment. While AMD was able to, seemingly unchallenged, to take over market shares from Intel in desktop and server/workstation segments with superior processors until a few months ago, Intel has regained its crown with its Core 2 Duo / Xeon 5100 processors. AMD may have underestimated the strength of Intel's technology as it can't really answer its rival's CPUs at this time.

A slight improvement to the current situation came with today's announcement of the high-end Quad FX platform, and is expected with new 65 nm processors in December. A changing situation, at least on the very high-end, could surface when AMD will unveil the first native quad-core in mid-2007. Analysts were able to get a sneak peek at the processor today, when AMD showed off a system running four 65 nm quad-cores - for a total of 16 processor cores. For comparison purposes, this is twice the number of cores that Intel can offer today (an in mid-2007) in comparable Xeon 5300 (Clovertown core) systems.

In many cases it may not matter that AMD can flaunt a "native" quad-core over Intel's Clovertown, which essentially integrates two Xeon 5100 (Woodcrest) dual-cores. For the enthusiast and high-end segment, there won't be much difference - if any - in performance. However, AMD claims that the integration of four cores into one piece of silicon will enable the company to maintain its current Opteron power envelope: Opteron product manager Steve Demski confirmed in a conversation with TG Daily that there will be Opteron quad-cores that will consume 68 watts, 95 watts and 125 watts. Not only are 68 watt quad-cores impressive (especially when compared to the 250 watt Quad FX), the fact that the power requirement remain unchanged will also mean that customers will be able to switch from dual- to quad-core without having to reconsider cooling technologies.

Details such as transistor count or clock speeds of the Barcelona CPU were not announced.

However, Demsky said that AMD wills tick to its easy upgrade promise: Opteron quad-cores (2000 and 8000 series) will continue to use socket 1207 and will be even available as socket AM2 versions later in 2007.

a possibilidade de ter 4 cores com um TDP de 68watts é uma boa bandeira. o chip, até nem ficou muito grande com o processo de fabrico de 65nm, olhando para a imagem.

pena é que os Engineering Samples, não estejam ao alcance do consumidor, para se ir tendo uma ideia da real performance disto tudo :(
 
AMD Demonstrates World's First Native Quad-Core X86 Server Processor


AMD today demonstrated the industry's first native quad-core x86 server processor, achieving four x86 processing cores on a single die of silicon. At the annual AMD Industry Analyst Forum, a server powered by four upcoming Quad-Core AMD Opteron processors (codenamed Barcelona), manufactured on 65nm silicon-on-insulator process technology, was shown utilizing all 16 cores. By delivering a consistent thermal envelope while adding two more processing cores, along with micro-architectural enhancements, AMD expects to significantly advance the performance-per-watt capabilities of AMD Opteron processors.


Demonstration Platform

AMD quad-core technology was demonstrated on a reference server platform running 64-bit Windows Server 2003. The four-processor server was powered by native Quad-Core AMD Opteron 8000 Series processors.

Quando a Intel mostrou os primeiros Quad-cores (dois Xeon 51xx "Clovertown", ou seja, 8 cores), fê-lo com o Cinebench e outros testes intensivos real-world.

A AMD faz uma demo do... Task Manager do Windows ?

Nao ia abrir o jogo já com benches.
Mostram que tb sabem fazer e xega para já.

Ao mostarem benches iam dar muita info á Intel para eles verem que CPU teriam que lançar para bater este da AMD.

Qual CPU a lançar daqui a 6 meses ? lol.
As velocidades dos "Yorkfield" já há muito que estão definidas.
Se há alguém que tem de fazer catch-up de performance (e performance por watt), é a AMD, não a Intel.
 
Última edição:
A AMD esteve bastante tempo à frente... o conroe é de outro mundo neste momento.

Mas nao é sobre isso que o tópico fala.

Todos estamos radiantes de saber se a competicao vai ser renhida, ´bom para nós, mas fanatismos sao efémeros.

Ás vezes parece que vejo meninos que nunca viram um AMD 64, passaram de Netburst para Conroe e pensam que hoje ganharam a aposta.

Espero ter o melhor produto ao melhor preco, quer seja AMD, quer seja Intel.

Esta estrurura, design da AMD parece ter futuro... Imaginem um Quad Core nativo com algo mais de muito bom em termos de GPU integrado.... agora estou eu também naquilo que poderá ser...

cumps ppl
 
eles que trabalhem que a intel precisa de boa concorrência senao os precos.. uppa uppa

se conseguissem cumprir os 65w para 4 cores era muito bom

se eles querem vedner isso em 2007 e bom que comecem a produzir senao depois nao ha capacidade produzir para tudo :P
 
Realmente é bem pequeno e ele estará para competir com o Penrin que ainda é muito maior que o Kentsfield.
Lá está, a AMD com 65nm vai conseguir competir com a Intel nos 45nm a nivel de Die-size.

O Penryn é muito maior que o Kenstfield ?

:lol: :lol:


1- O "Penryn" é um dual-core a 45nm (vem para substituir os actuais Core 2 Duo "Merom" nos portáteis), não um quad-core.

2- O actual "Kentsfield" é feito a 65nm, o "Yorkfield" (esse sim, um quad-core) é fabricado a 45nm.

3- Mesmo na actual configuração, o "Kentsfield" pouco maior é do que o *futuro* concorrente da AMD, apesar de ter mais memória cache do que o K8L quad-core (8MB de L2, contra 2MB de L2 e 2MB de L3).

4- O Yorkfield vai aumentar a parada com mais 4MB de L2 (total de 12MB), novas instrucções SSE4, velocidades a começar nos 3.0 GHz, e aínda TDP's muito mais baixos.

5- Para o "Wolfdale" (versão desktop do "Penryn" dual-core), estão previstos TDP's de 57W para a versão a 4 GHz, enquanto o equivalente AMD K8L dual-core ("Antares") chegará com velocidades de 2.0 a 2.9 GHz, com TDP's -para a versão mais rápida- de 89W.

6- O "Yorkfield" quad-core tem previstas velocidades de 3.4 a 3.73 GHz, contra 2.7 a 2.9 GHz para os AMD K8L equivalentes.

Pá, enganei-me no nome, é obvio que tava a falar do yorkfield quad-core.

Simplesmente disse que se o K8L quad core ja é mais pequeno que o Kentsfield, entao com os 12mb cache do yorkfield vai parecer minúsculo mesmo tando a Intel á frente no processo de fabrico por alturas de Q2/Q3 2007.

Estamos a discutir aspectos da die size do K8L Quad-core.
Simplesmente tornei claro que estavas errado (e continuas a insistir no teu erro, aliás) quando afirmas que o K8L QC a 65nm é mais pequeno do que o Yorkfield a 45nm.

Isso é uma falsidade.

AMD aims to reclaim CPU crown with 2007 quad-core

Berkeley (CA) - AMD yesterday presented the first native quad-core CPU, a processor that combines four cores within one die, to analysts. Few details have been provided at the time of the announcement, but the puzzle is coming together and suggests that AMD may have a shot at trumping Intel by mid-2007, at least until the blue team rolls out 45 nm chips.

Not quite half a year later, analysts have seen this quad-core processor in a monstrous system: As reported yesterday, the Barcelona Opteron was demonstrated in a 4P system, resulting in a total of 16 processor cores. AMD flaunted its lead in this segment, as Intel currently is able to run only 8 cores - which consume more power than AMD's 16 - in a comparable system.

AMD claims that its native quad-core will not consume more power that the current dual-core Opteron line-up, meaning that the company will offer 68 watt, 95 watt and 125 watt power envelopes. A consistency of power envelopes is important especially for the enterprise segment, as companies are able to simply upgrade from an Opteron dual core (AMD will offer quad-core CPUs with 1207 and AM2 sockets) to a quad-core without having to reconsider cooling requirement. In that view, a Barcelona update is as simple as open the case - drop in the chip - close the box.

Barcelona, technical details

On the technical side, AMD has chosen a very different road to quad-core. Integrating all four cores under one roof, the Barcelona chip will reserve 64 KB of L1 cache and 512 KB of L2 cache for each core, which, according to the company, will avoid access conflicts that can happen in shared caches (Intel claims that its "SmartCache" avoids such conflicts in shared caches as well). Barcelona will also use a shares 2 MB L3 cache, which can be expanded "at the right time."

The 65 nm - Barcelona will be the first 65 nm Opteron processor - architecture also integrates Hypertransport links with a bandwidth of up to 8 GB, dual 128-bit SSE data interfaces, a new crossbar design, enhanced power management, and support for DDR2 memory. Comparable to Intel's Core technology, AMD is able to control the load on each processor core. If there is no need to use all four cores, only one, two or three cores will be filled up with data, which causes one or more cores to sit idle. As a result, power consumption can drop dramatically (see slideshow for details).

AMD has not provided performance data for Barcelona, but initial presentations let us believe that AMD is not only aiming to match Intel's Clovertown processor. Barcelona is positioned as a new, scalable platform that could carry AMD for some time. On the desktop side, Barcelona is related to the Agena FX (Athlon 64 FX) and Agena (Athlon 64 X2) processors, which are scheduled to be released in early Q3 2007. Agena cores will be clocked between 2.7 GHz and 2.9 GHz, will be manufactured in 65 nm and also use socket 1207.

At least from today's view, AMD has an opportunity to make up lost ground and regain technology lead for at least six months in 2007. The open questions are how strong Intel's Penryn will be and how AMD's strategy to integrate ATI technology into its platforms will develop over the next 12 to 24 months.
