Barcelona... 1ºs benchs!

Desculpem lá qualquer coisinha, eu não percebo lá muito de arquitecturas de processadores e afins. Por isso expliquem me lá como se fosse um burro :lol:. A AMD vem ai outra vez para competir com a Intel ou será que a Intel vai continuar na mó de cima por enquanto e quem paga é o consumidor?

P.S. : Sem onfença é que eu olho para os vossos Posts e para mim existem alguns que parecem grego :p
 
É simples. Daquilo que eu sei de programação, se utilizas variaveis inteiras, ele vai conter valores do tipo: 3; 35; 67, etc....
Se utilizas as Float, que são as que estão preparadas para receber numeros que podem ser inteiros ou n. Por exem.: 3,63326; 15,155; etc....

No caso da AMD, ela safa-se bem melhor com as Float. Isto segundo estes graficos

Pronto, acho que é isto, se estiver errado digam-me

:kfold:
 
Em geral os jogos puxam mais pelas unidades floating point.
Tenho a ideia q usam mais Integer.
Bem visto. Assim aparentemente os k10 devem ser ligeiramente melhores que os C2Q em INT e muito melhores em FLOAT.
Em jogos esta superioridade em Float vai ser uma maravilha.
Os Specs_rate são mais para servers onde os cores estão todos a ser usados e precisam de bastante bandwidth.

O SPECint e o SPECfp é q vão ditar como é q as coisa vão correr no desktop pq testam o core em si, e pelos scores q andam ai o K10 vai conseguir empatar e nada mais, mas tambem basta ver a melhoria "miraculosa" q os xeons tiveram de Agosto para Setembro no slides do George Ou e ver os scores muito mais baixos q os mesmos Xeons tiveram quando sairam, para perceber que estes scores do K10 ainda estão "verdes" e que de certeza com a quantidade de sistemas q vão ser submetidos na SPEC, provavelmente vão subir mais.
 
os Barças só têm mais 15% de vantagem em relação ao K8... plo menos já tão mais rapidos... ainda ñ é desta k a AMD se levanta, pode ser k com mais clocks consiga subir a parada... para já parece-me +/- ao nivel da intel (actualmente)... Só achei preocupante o que os gajos disseram do server ter pifado, apenas ligava as fans e ñ fazia post... espero que seja mesmo 1 "glitch" isolada e que a AMD ñ tenha apressado os CPU's pro mercado sem estarem a funcar a 100%, isso é que matava a AMD, a reputação ia por aí abaixo... Espero que eles melhorem para dar concorrência à Intel, para ver se já obriga a Intel a dar o "CSI" ao Nehalem.
 
Final Words

We can't draw too many sweeping conclusions based on the data here today, but here's what we do know:
- Gaming performance is much improved with Barcelona over K8, this is most likely a result of the improvements to the SSE engine and the wider front end of the core.
- Encoding performance is improved (again SSE128 rearing its head), but 3dsmax saw an unexpectedly large performance improvement.
- With a 10 - 15% increase in performance on average, Phenom should be more competitive than K8 was on the desktop (as expected).
Here's where things get complicated; we knew Phenom/Barcelona would be faster clock for clock, it was only a matter of how big of an improvement we'd get. If we are to believe that 15% is the best we'll get on average, taking into account that Penryn is around 5% faster than Conroe, the updated architecture from AMD alone isn't enough to really compete with Intel. In other words, price matters.

We saw how competitive AMD became after the first round of price cuts this year, but after the second set Intel went back to dominating. The trouble for AMD this time around is that Phenom is a much larger chip than the outgoing Athlon 64 X2, whereas Intel's Penryn family will actually be smaller than Conroe. AMD is already losing a considerable amount of money each quarter, so fabbing a larger chip at the same price as current CPUs will only make the situation worse. However, Intel can afford to continue to keep its processors as aggressively priced, especially moving to 45nm.

To put it plainly: Phenom/Barcelona make this price war more difficult on AMD, while Penryn makes it easier on Intel. What's the end game? Is there a solution? We're not sure, all we know today is a starting point for Phenom expectations.

As coisas são que a AMD nem estava assim tão atrás em desempenho como se pensa. Em stock, os K8 eram relativamente competitivos face aos Core 2 Duo de preço semelhante. As grandes vantagens da Intel foram a baixa de preços, os novos C2D E6x50 e o overclock. Agora com o aumento de desempenho, e com a hipótese dos barcelona escalarem bem, o mercado ficou a ganhar
 
That said, new processor microarchitectures often scale quite well with clock speed, and our sneak peek at the 2.5GHz Opteron 2360 SE suggests Barcelona might be that way. Still, one can't help but wonder whether AMD did the right thing with its L3 cache.

That cache's roughly 20ns access latency erases the Opteron's lifelong advantage in memory access latencies, yet it nets an effective total cache size just over half that of the current Xeon's. Since the L3 cache is clocked at the same speed as the memory controller, raising that memory controller's clock speed should be a priority for AMD. This particular issue may be more of a concern in desktops and workstations than in servers, however, given the usage models involved.

Nonetheless, AMD now faces some harsh realities. For one, it is not going to capture the overall performance lead from Intel soon, not even in "Q4," which is when higher-clocked parts like the Opteron 2360 SE are expected to arrive. Given what we've seen, AMD will probably have to achieve something close to clock speed parity with Intel in order to compete for the performance crown. On top of that, Intel is preparing new 45nm "Harpertown" Xeons for launch some time soon, complete with a 6MB L2 cache, 1.6GHz front-side bus, clock speeds over 3GHz, and expected improvements in per-clock performance and power efficiency. These new Xeons could make life difficult for Barcelona. And although AMD should remain competitive in the server market on the strength of Opteron's natural system architecture and power efficiency advantages, this CPU architecture may not translate well to the desktop, where it has to compete with a Core 2 processor freed from the power and memory latency penalties of FB-DIMMs. But that, I suppose, is a question for another day.

Última edição:
O K10 tem um "bright spot", escala muito melhor por mhz's, ou seja a velocidades mais altas as diferenças vão ser menores e talvez quem sabe com uma plataforma mais madura e novos steppings, pode mesmo ultrapassar os c2d a 45nm, o problema vai chegar a essas velocidades rapidamente...
 
Pelo que me parece a AMD vai continuar atrás da Intel durante longos meses.
Aqui não me parece que haja drivers que lhes salvem a face...
Têm que se aplicar com a Radeon porque me parece que esta arquitectura e a diferença de MHZ vai fazer que nos próximos anos, pelo menos, a Intel vai continuar à frente.
A não ser que a AMD tire algum coelho da cartola.
 
Apesar de faltarem muitos benchmarks, no mercado de servidores, este Opteron parece ser bastante interessante, comparado com um Xeon com os mesmos clocks.
Os preços também não estão nada maus.
 
No mercado servidores parece estar bem. O consumo é muito baixo pq nao necessita de FB-dims e as boards consomem menos, mas no desktop isso ja nao vai acontecer.

Para o Desktop vai ser mais complicado, mas ai quero ver uma RD790 com memorias de jeito e nao DDR2-667 + Nforce 2200 como nos servers.
A ver se no Phenon Desktop tb lançam uma nova revisão do CPU com muito mais Mhz.

E assim começamos a ter concorrência tb nos CPU´s mesmo a tempo do Natal :)

Anyway este lançamento parece somente para a AMD começar a fazer dinheiro enviando os CPU´s para updates a servidores de grandes empresas. E desta forma também acalmar os accionistas.

O grande lançamento para o nós sera só com o Phenon X4 para o desktop com o RD780/RD790 daqui a uns 2 meses.
 
Última edição:
O problema é que Phenon X4..... €€€€€€

Ou melhor, não é para todos... Só para alguns!

Não será assim tão caro olhando para o preço dos Opteron.
O Phenon Fx é que deverá custar um balburdio.

Os K10 este ano tb so vao contar para 10% das vendas por isso de qualquer das maneiras nao serão muitos á venda.
 
Última edição:
A política da AMD não tem sido essa, pelo menos ultimamente.

E daqui até ao lançamento dos Phenom X4, ou muita coisa é "afinada" ou então a INTEL vai

continuar a fazer da AMD uma rodilha, pelo menos nos desktop, que muito sinceramente, é o que me interessa.

Ainda assim, estou confiante que daqui até ao Natal vai passar muita água pelo moinho, e pode ser que a AMD ainda nos surpreenda, ou não...:-D

AMD Introduces Quad-Core Barcelona

AMD today introduced the Quad-Core AMD Opteron processor, the world’s most advanced x86 processor ever designed and manufactured and the first native x86 quad-core microprocessor. Designed from inception for the most demanding datacenters, Quad-Core AMD Opteron processor-based servers from global OEMs and system builders can deliver breakthrough capabilities to customers in a time of dramatically escalating performance-per-watt emphasis.


Quad-Core AMD Opteron processors with AMD’s revolutionary Direct Connect Architecture introduce innovations that go beyond four x86 processing cores on a single die of silicon. Critical considerations for today’s most challenging business requirements inspired Quad-Core AMD Opteron processor innovations: energy efficiency with a 50 percent increase in integer and floating-point performance, enhanced virtualization performance, and investment protection via a customer-centric approach enabling non-disruptive transitions from dual- to quad-core within the same power and thermal envelopes to help keep infrastructure costs down.

“Today marks one of the great milestones in microprocessor achievement as AMD again raises expectations for industry-standard computing,” said Hector Ruiz, chairman and chief executive officer, AMD. “We’ve worked closely with our customers and partners to design a new generation of processing solutions embodied by today’s Quad-Core AMD Opteron processor – a four-way winner in performance, energy efficiency, virtualization and investment protection. Early customer response has been extremely positive.”

Quad-Core AMD Opteron processor-based systems from global OEM and system-builder partners begin shipping this month and are expected to increase in number through the remainder of the year. AMD Phenom processor solutions, which will leverage many of the same benefits of this innovative, next-generation architecture, are expected to be available for the desktop market in December. Due in part to the industry’s most stable x86 server platform, more than 50 socket compatible Quad-Core AMD Opteron processor-ready system choices are on the market today from tier one OEMs, all of whom are publicly supporting today’s introduction.

“Today more customers choose ProLiant for their AMD processor-based server blades than any other vendor by a factor of more than 2 to 1. HP offers customers a broad portfolio built on innovative designs to address customer needs in the areas of power, virtualization and cost,” said Paul Miller, vice president, marketing, enterprise storage and servers, HP. “With today’s launch of Quad-Core AMD Opteron processors, we can help customers bring new levels of efficiency to their infrastructure as we broaden our AMD Opteron processor-based family of servers.”

“Sun is thrilled about the introduction of Quad-Core AMD Opteron processors. Incorporating Sun’s innovative design principles that enable stunning scalability and industry-leading performance-per-watt, our upcoming Quad-Core AMD Opteron processor-based servers and workstations will only accelerate the momentum Sun is experiencing in its x64 business,” said John Fowler, executive vice president of Sun Microsystems’ Systems Group. “With so much pent-up demand for the scalability of native quad-core processing, Sun believes there will be rapid, widespread adoption of Quad-Core AMD Opteron processor-based systems. We applaud AMD for yet another technological breakthrough, and are excited to continue to grow our alliance.”

“Dell and AMD share a commitment to delivering industry-leading performance, performance-per-watt, and the most energy-efficient product designs to help our customers focus on driving their business forward,” said Brad Anderson, senior vice president, Dell Product Group. “Dell’s ability to seamlessly deliver the benefits of AMD’s Dual Dynamic Power Management technology means our customers can get more today and for future growth in the AMD processor-powered Dell PowerEdge 2970 and Energy Smart 2970.”

“IBM was the first global OEM to support AMD Opteron processors in 2003. Today our relationship is delivering powerful and energy-efficient business performance computing solutions” said James Gargan, vice president, Brand Management System x & BladeCenter, IBM. “Our x86 systems feature IBM’s X-Architecture innovation, such as Xcelerated Memory Technology, to help optimize Quad-Core AMD Opteron processor capabilities for peak system performance. We look forward to bringing new products to market with AMD later this year to help strengthen IBM’s position as the world’s top server vendor.”

Systems based on Quad-Core AMD Opteron processors are also being announced today by a host of other manufacturers, including Appro, Egenera, Gateway, Rackable Systems, Supermicro and Verari.

Additionally, AMD is providing the channel with a tremendous opportunity to be able to offer their customers Quad-Core AMD Opteron processor-based solutions very soon after launch. AMD Validated Server Program platforms are available today through distribution, empowering channel partners with the opportunity to be early to market with solutions.

AMD introduces Average CPU Power (ACP)
AMD also today introduced the Average CPU Power (ACP) metric, which represents processor power usage, including cores, integrated memory controller, and HyperTransport technology links, while running a suite of typical and relevant commercially useful high utilization workloads to be more indicative of the power consumption that end-users can expect. ACP is a useful metric for data center operators when estimating power budgets to size their datacenters. AMD will continue to provide thermal design power (TDP) specifications to platform designers in AMD power and thermal datasheets.

AMD is introducing Quad-Core AMD Opteron processors today at the 55- and 75-watt ACP. For system designers, AMD will continue to state its TDP specifications.

New Standard in Energy Efficiency
As datacenters in the U.S. face the potential of doubling their energy consumption by 20113, new Quad-Core AMD Opteron processors introduce the world’s most energy-efficient x86 architecture, bolstered by a variety of new power-saving technologies, including:
  • AMD CoolCore Technology, for reducing energy consumption by turning off unused parts of the processor;
  • Independent Dynamic Core Technology, an enhancement to AMD PowerNow! technology, allowing each core to vary its clock frequency depending on the specific performance requirement of the applications it is supporting; and
  • Dual Dynamic Power Management (DDPM), which provides an independent power supply to the cores and to the memory controller, allowing the cores and memory controllers to operate on different voltages, determined by usage. DDPM is available in most Quad-Core AMD Opteron processor-based platforms being introduced today.
“Microsoft and AMD are working together to drive innovation, performance and energy efficiency across the datacenters and development environments,” said Bill Laing, general manager of Windows Server Division at Microsoft Corp. “With 64-bit multi-core technology, Direct Connect Architecture and built-in virtualization, AMD Opteron processors continue to provide Microsoft Windows customers with an innovative platform. Looking ahead, we believe Windows Server 2008, SQL Server 2008 and Visual Studio 2008 running with Quad-Core AMD Opteron processors will provide a compelling development and deployment platform to drive customers’ dynamic IT environments.”

Optimal Virtualization Performance
Datacenters depend on virtualization software as an essential tool to consolidate server workloads, operate more securely, and enable disaster recovery. Quad-Core AMD Opteron processors with Direct Connect Architecture excel in virtualized environments because of the integrated memory controller for reduced memory latency, and Rapid Virtualization Indexing, a new AMD innovation in AMD Virtualization technology designed to reduce the overhead associated with software virtualization. Rapid Virtualization Indexing takes functionality that was previously performed in software and greatly accelerates it by performing those functions within the CPU to help enable near-real time application performance.

Investment Protection
Quad-Core AMD Opteron processors maintain compatibility with the socket and thermal envelopes of Second-Generation AMD Opteron processors to enable a seamless customer upgrade path. AMD’s common core strategy empowers customers to scale with one AMD architecture to reduce platform management complexity and increase datacenter uptime and productivity.

Outstanding Performance
Continuing the legacy of the AMD Opteron processor family, Quad-Core AMD Opteron processors introduce several new ground-breaking technologies enabling impressive results across a suite of benchmarks. Within comparable thermal bands, Quad-Core AMD Opteron processors outperform the competition on several industry-standard benchmarks including: SPECfp_rate2006, SPECint_2006, SPECompM2001Base, STREAM, Fluent and LS-DYNA.
