Processador AMD 45nm CPU naming scheme changed

Os consumos baixaram mesmo à pique, o que é mesmo muito bom. Questiono se terá sido apenas consequência da passagem para os 45nm. Os Phenom actuais têm consumos absurdos, e com este resultado deve colocar mais em par com os Core da Intel.

Pelo contrário não fiquei tão impressionado com a performance que estes novos CPUs ganharam. O máximo de ganhos que vejo ronda os 10% e acho que não é suficiente.

Shanghai to have high clocks, performance, says AMD

As the release of 45nm Opteron processors grows nearer, AMD executives are loosening their tongues and shedding more light on the upcoming chips. CNet has had a chat with AMD Server and Workstation General Manager Pat Patla, who painted an encouraging picture of the chipmaker's progress.

Speaking of Shanghai—the code name for 45nm Opterons—Patla said AMD is working hard not to repeat past mistakes: "We had some mis-starts in getting Barcelona to market and wanted to bring as much velocity to Shanghai as possible." To that end, a lead engineer oversees the Shanghai project and sets goals so that "the product that we put in the hands of our partners is going to be of substantial stability so they can do lots of early validation."

Patla hinted that Shanghai may zoom past Barcelona in benchmarks, too. He said the 45nm process yields "a lot more (clock) frequency," and at the same clock speed, Shanghai "will outperform Barcelona by about 20 percent." AMD's retail quad-core chips currently top out at 2.6GHz, so Patla's statements give weight to rumors of 45nm Phenoms clocked at up to 3GHz.

On the scheduling side of things, Patla said servers featuring 45nm Opterons will ship in the fourth quarter of this year. The schedule for 45nm Phenoms seems a little fuzzier, since AMD told CNet the chips will "launch in the fourth quarter of this year or first quarter of 2009." The rumor mill pins that launch in late December or early January.

"Shanghai" is Ready to Rock says AMD

AMD Shanghai hopes to erase bad memories of Barcelona

AMD has proven to be a tough opponent for Intel in the server processor marketplace. AMD said that its latest architecture dubbed Shanghai is now ready to go. Shanghai parts are quad-core processors that are targeted at the server market.

Shanghai is also AMD's first 45-nanometer processor. AMD's last big architecture aimed at the server marketplace was the Barcelona processor that ran into significant problems in the market. One of the biggest issues with Barcelona was that the processors were delayed for eight months after their introduction.

Once the processors were finally shipped and available, AMD had issues with the performance of the parts and the CPUs suffered from other glitches. AMD promises that Shanghai will not be another Barcelona.

Pat Patla, AMD server and workstation business general manager, told CNET News, "We had some mis-starts in getting Barcelona to market and wanted to bring as much velocity to Shanghai as possible. Learn from our mistakes and, as a company, never do that again."

To help ensure that Shanghai succeeds and offer users a better experience than Barcelona, AMD put one engineer in charge of the entire Shanghai project. Patla continued saying, "the product that we put in the hands of our partners is going to be of substantial stability so they can do lots of early validation."

To improve the performance of Shanghai over Barcelona, AMD is counting on several factors. First is the move from the 65nm process of Barcelona to the 45nm process used in Shanghai. This will allow for more efficiency and better performance than Barcelona.

AMD is also moving the cache memory from 2MB to 6MB to improve performance and it says that instructions per clock cycle will be increased as well. Shanghai will also utilize AMD's HyperTransport 3, which AMD expects to be validated in Q1 2009. A 45nm desktop Shanghai part will be offered in Q1 2009 according to CNET News.

AMD to launch nine 45nm Shanghai server CPUs in October

AMD has updated server makers that it is planning to bring forward the launch of 45nm server processors (Shanghai) from the original schedule of January 2009 to mid-October. Nine CPUs with core frequencies between 2.3-2.7GHz will be offerer ed initially, according to sources at server makers.

The nine Shanghai processors will include five 2-way and four 8-way models. All will support the company's socket F (1207), and include an on-die DDR2 memory controller and 6MB L2 cache.

In February 2009, AMD will launch five 55W low-voltage server CPUs – three 2-way and two 8-way – and two 105W high-performance models – one 2-way and an 8-way.

Shanghai processors will only support HyperTransport 1.0 initially. Models supporting HyperTransport 3.0 will be released in the second quarter of 2009. AMD is also planning to launch a new server chipset (SR5600) in the second quarter of 2009, the sources added.

Deneb does 4.3GHz on air, launch approaching

Many readers have been getting back to us regarding the unusually positive reports about AMD lately. I guess we became colored a bit by our love for the Radeon HD 2900 XT cards when no one really cared for them, but then again our favorite games are of the 3DMark series and not of the interactive type, and there the Radeon 2900 XT was a lot of fun. However, we always used Intel's processors together with the card(s), and even though we don't see a change in that anytime soon, the everyday overclockers may get a change of heart with the new AMD models based on the Deneb core.

A while back we reported on a recent interview with AMD General Manager of AMD's Server and Workstation chip business, Pat Patla, where he claimed that Shanghai is much more than a mere die-shrink and that it is 20% faster than Barcelona clock per clock. We've been told by a second source that 20% may be a bit much, but that there is an IPC boost to expect, but closer to 15% than 20. In either case it's just a nice boost. This is applies for Deneb as well we've been told.

The source even indicates that since Nehalem isn't that much of a desktop upgrade, but server mostly, Deneb will become the gaming processor to get. We have no secondary confirmation at this time, but we wanted to forward the information. In fact, source also says that Deneb was able to do 4.3GHz under a Scythe Mine cooler, stable of course. It's very important to use the right motherboard though, you will need the SB750 southbridge to begin with.

Most people should be able to hit 3.6GHz with a decent cooler, source says. The most amazing is that the processor should still run fairly cool and consume less power than Intel equivalents. Comparing Intel's new processors to AMD's new, Intel is gaining on the server market, while AMD will be trying to get back the retail market. We will not have to wait long for it to happen either, mass production is well under way and launch is approaching.

Fantástico, e é como ele diz, se os Nahalem são virados para server, é uma boa altura para estes meninos saírem.

4.3Ghz a ar é muita fruta, comparando com os outros que nem 3Ghz estáveis davam...


Cumps
 
Já tinha lido isso, parece que vai ser mais um amd phoenix do que phenom, gostava que tal se viesse a confirmar, mas até agora ainda não se viu muito de concreto. Agora a ver é se mantêm a politica de preços.

E os cold bugs, continuam??

é bem capaz. o coldbug é um resultado do processo de fabrico (soi) e não do desenho do cpu.

Não sei porquê, não acredito nesta notícia, parece-me um salto demasiado grande para ser verdade.

não é assim um salto tão grande, já se conseguem ver processadores actuais a correrem a 3.6 (mesmo em sb600)

Mas afinal quando é que os processadores desktop vão sair, agora em Outubro/Novembro ou Janeiro?

8 de Janeiro é que serão disponibilizados ao público
