Para quem julga que AMD ainda está ai para as curvas...

«...Nehalem effectively includes the only remaining advantages AMD held over Intel with respect to memory performance and interconnect speed - you can expect a tremendous performance increase going from Penryn to Nehalem because of this. Intel is expecting memory accesses to be around twice the speed in Nehalem as they are in Penryn, which thanks to its aggressive prefetchers are already incredibly fast. If you think Intel's performance advantage is significant today, Nehalem should completely redefine your perspective - AMD needs its Bobcat and Bulldozer cores if it is going to want to compete...»

Intel Discusses GPU, Hybrid CPUs

Intel looks to get into the graphics market in 2009, and in a big way

Next month heralds the 2008 Spring Intel Developer Forum in Shanghai, China. Pre-show briefings opened up with a quick mention on the status of Larrabee, Intel's upcoming graphics core.

Larrabee differs significantly from AMD's Radeon and NVIDIA's GeForce processors. For starters, Larrabee is based on the x86 instruction set found in CPU architecture. Intel vice president Steve Smith emphasized that Larrabee is not just a GPU, but a multi-core die capable of any stream processing task.

Smith would not detail exactly how many cores reside on Larrabee, though early schematics from 2006 detail designs with 16 cores. Each in-order core is capable of operating in excess of 2 GHz.

Larrabee can apparently scale to several thousand cores, sharing much of the same research as Intel's Tera-scale project. In addition to the x86 approach, the company announced it will soon announce another SSE-like extension set, dubbed Advanced Vector Extensions. These extensions will likely be what separates Larrabee's x86 instruction set from the x86 instructions featured on Core 2 Duo and Phenom. Smith said Larrabee will support OpenGL, DirectX and ray-tracing instructions.

However, to much disappointment, Larrabee will not find a home on 45nm Nehalem processors, scheduled for an early 2009 launch. Smith said Larrabee samples will be ready in Q4 2008, with shipments in 2009, though the initial launch appears to be only for discrete computing.

Likely, CPU integration of Larrabee will not come until the 32nm shrink of Nehalem, codenamed Gesher, if ever.

An Intel engineer tells DailyTech, "You have to walk before you can run." Walking, at Intel, means integrating a much simpler GPU into the processor first.
Intel’s hybrid CPU and GPU chips are set to be released in two flavors, both of which will be based on the Nehalem CPU architecture. The first version, dubbed Havendale, will be a desktop chip, while the second version, dubbed Auburndale, will be a notebook chip.
Auburndale and Havendale will have two Nehalem cores paired with a graphics subsystem. The twin cores will share 4MB of L2 cache and feature an integrated dual-channel memory controller that supports memory configurations up to DDR3-1333.
The graphics subsystem will be initially derived from Intel’s G45 integrated graphics. This indicates that neither Auburndale nor Havendale will be for heavy graphics processing, but will be more of an integrated graphics replacement.
In fact, both graphics cores leave out support for key features of DirectX 9 and DirectX 10. Supposedly, this G45-derived core will eventually be replaced by a cut-down Larrabee graphics processor, or a derivative.

According to Intel roadmaps, the new processors are expected to enter the market in the first half of 2009. This beats out the expected time of arrival of AMD’s Fusion processors, which are planned to debut in the second half of 2009.

In the meantime, Smith promises the discrete Larrabee offerings will compete competitively with Radeon and GeForce offerings when its finally announced.

Larrabee POWA!


Opening the Kimono: Intel Details Nehalem and Tempts with Larrabee

Prior to its Intel Developer Forum, Intel is revealing a bit more detail on some new products coming down the pipeline - including Nehalem and Larrabee.
PICT0016.JPG
IDF is going to be all about scaling Intel Architecture from milli watts all the way up to Peta FLOPs. This is clearly a reference to the Intel Atom on the milli watts side and new high end quad-core Itanium and Larrabee products on the Peta FLOPs side.
First up is Intel's quad-core Itanium product, codenamed Tukwila:
...

PICT0017.JPG
Tukwila is Intel's first chip with a full 2 billion transistors and should be shipping by the end of this year, with full systems available next year. Tukwila, like Nehalem, will support Intel's QuickPath Interconnect (QPI), a point-to-point interconnect similar to AMD's Hyper Transport. Also like Nehalem, Tukwila will feature an integrated memory controller - two in this case.
Next up was the Intel Dunnington processor, a 45nm 6-core Xeon part based on Penryn cores:
...
PICT0019.JPG
With 6 cores (3 dual-core pairs on a single die) and a massive 16MB shared L3 cache, Dunnington is close to Tukwila in transistor count, weighing in at a whopping 1.9 billion transistors. Dunnington is the first shipping product to come out of Intel's India Design Team based out of Bangalore, India.
...
Architecturally there's not much difference between Dunnington and current Penryn based Xeon parts, you simply get more cores and a very large L3 cache shared by all of the cores. Designing such a beast isn't an insignificant effort, but it's made easier because when Intel designs a core it designs everything up to but not including the L2 cache. The L2 and everything external to it is referred to as the "uncore" and is made somewhat modular, although not quite to the same degree as Nehalem.
Dunnington is the first step in Intel implementing a very Phenom-like cache architecture with its future Core products, culminating in Nehalem.

lá está a intel a tentar fazer como a asus e a meter-se em todas as áreas, se n acabar como a asus que n consegue controlar a qualidade de tudo como se tivesse apenas alguns produtos tudo bem.

6 core:wow::wow:?? quero ver aplicações a usar tantos cores, isso só se for pra servidores.

Por acaso é.
Se reparaste no slide que eles deram, é referida a compatibilidade do "Dunnington" (6 cores, single-die) com a plataforma "Caneland".

Ora, como eu disse no meu blog, essa plataforma é para servidores de alta densidade e blades que usem o Socket 604 (em vez do LGA 771 dos Xeon "normais", ou do LGA 775 dos Core 2 para desktops), pelo que o "Dunnington" destina-se exclusivamente ao mercado de upgrades das CPU's "Paxville", "Tulsa", "Tigerton", etc.

Eu sinceramente penso que devemos "ter fé" que a AMD de alguma luta, pois tudo o que é monopólio é mau para o zé povinho, preços mais caros, desenvolvimento mais lento, etc, etc, etc...

neste momento a INTEL está no topo, não há duvida, muito me espantou o tempo em que eles estavam por baixo, tendo em conta a disparidade de recursos entre a Intel e a AMD, o mercado está como deve estar, infelizmente... a Amd está a recorrer ao preço para se tornar competitiva, a ver vamos se esses triple cores sao bons em termos qualidade/preço, que para 80% das pessoas é o que interessa, o mercado de topo não é para todos!
 
AMD Not Intimidated By Nehalem


Intel's announcement about their forthcoming CPU architectures hasn't fazed AMD. In fact AMD claims that the integrated memory controller and QPI sound a lot like features AMD CPUs have had for several years now. What's even better is that AMD more or less tipped their hand regarding AMD's future CPUs:

On Dunnington (AMD's Randy) Allen said that AMD’s forthcoming Shanghai will be 45nm. “In 2009 we will have enhancement to hyper threading with HT3, DDR3 technology and eight cores or more. We’ll have six cores by the end of the year and you can expect to see eight cores in the 2009 timeframe,” he said.

If AMD manages to squeeze two Shanghai quad-cores onto a single CPU package, the fight between Nehalem and Shanghai could be very interesting indeed.

IDF 2008 Day 1: Intel Nehalem Working at 3.2GHz Pictured


I promissed more details on Intel Nehalem yesterday, and now it is time to keep my word. During the first day of Spring IDF 2008, the guys over at HEXUS.net have pictured the first working sample of a quad-core Intel Nehalem processor operating at 3.2GHz (revision A1). The 1366-pin, 731M-transistor 45nm native quad-core model, utilizes 256KB of L2 cache for each core, as well as 8MB of L3 cache. The CPU also integrates triple-channel DDR3-1333MHz memory controller and SSE4 instructions. Like the new 533MHz Silverthorne-based Atom processors, Nehalem will also incorporate Simultaneous Multithreading (SMT) which is also known as Hyper-Threading (HT). Each physical core in a single Nehalem processor is paired up with its own virtual core. As a result, the quad-core processor will be detected to have eight cores (on the picture). Predictions say that this new architecture will offer around 30% better performance, on a clock-for-clock basis, when compared to Core 2, in a heavily-multithreaded environment - HPC and low-end servers, mainly. Current Intel roadmaps list the Nehalem launch date for Q4 2008, with a simulteanous rollout across servers and desktops.

Ja agora gostava de saber com que boards é que eles testaram isto, P45 com o socket novo!?:rolleyes:
Ou como o controlador de memoria ja é no CPU, isto só tem South Bridge, como nos K8!?

Os chipsets da AMD não dispensaram a Northbridge, apesar do controlador de memória estar integrado na CPU.
A Nvidia foi a única a fazê-lo até ao momento.

O chipset usado na apresentação da Intel foi o "Tylersburg" -nome de código-, cujo tape-out foi no Verão passado, mas só será lançado com a família "Nehalem", lá para o final deste ano.
O equivalente para os "Nehalem" nos desktops será o "Kingscreek".

Esperemos que estas velocidades sejam de ser apenas novos e que subam ainda mais:D,não há pics da board e do CPU em si?
 

Artigo bastante interessante, e a frase final resume a situação toda:

AMD never really caught up to the performance of Conroe, through some aggressive pricing we got competition in the low end but it could never touch the upper echelon of Core 2 performance. With Penryn, Intel widened the gap. And now with Nehalem it's going to be even tougher to envision a competitive high-end AMD CPU at the end of this year. 2009 should hold a new architecture for AMD, which is the only thing that could possibly come close to achieving competition here. It's months before Nehalem's launch and there's already no equal in sight, it will take far more than Phenom to make this thing sweat.
 
Pergunta parva, o que acontece depois dos processadores chegarem aos 0/1 nm ? Desculpem a ignorancia, e desculpem desenterar isto

nunca atinges o 0 nm. Talvez daqui a muitos anos se atinja a fracção de um nm (mesmo assim uma fracção muito grande). Chegas a um ponto nao podes dividir o atomo do material não é verdade?

1 nm são 10 moleculas de qq coisa alinhadas se nao estou em erro :P Só vais deixar de poder diminuir o processo de fabricação enquanto poderes dividir a material física.
