Os novos drivers SLI já não requerem que as duas placas sejam da mesma marca e até toleram a ausência da Bridge, com uma pequena penalização no desempenho. Ah, e não é necessário comprar uma placa "master"...
Esperem mais novidades do SLI para breve, é que a Gigapixel e as suas patentes aínda são da Nvidia...

DJ_PAPA disse:Já há info na net sobre o SLI2.0
Tem por base o uso de 2 placas iguais, mas com um bus de 16 lanes para cada grafica, em vez dos 8 para cada.
Era esta a principal diferença.
É claro que uma nova board será lançada para o SLI2!
Ja que se esperou tanto tempo pelo crossfire e pela R520, tb se pode esperar mais um bocadinho que ja falta pouco
Concorrencia é sempre bem vinda e necessaria. Daqui a 1 mes e até a Fevereiro as coisas vao aquecer... e de que maneira....

ATI Technologies chief executive office Dave Orton recently made some additional claims about the forthcoming graphics series code-named R500. As it appears, the company has run into multiple issues with its chips called R520 and RV530 that run at high speeds, but did not experience any problems with the RV515 and Xenos chip for Xbox 360 console that run at moderate frequencies.
“To be honest, we’ve had our share of challenges with the R520 and RV530 chips. Even though all the simulations that were done with the chips were looking good, there were still issues with the silicon when it came back from the fab,” said Dave Orton, ATI’s chief executive officer, in an interview with Sonera Plaza web-site.
ATI’s code-named R520 chip is to be targeted at enthusiasts and is expected to offer performance that significantly exceeds the level provided by ATI’s current RADEON X850 XT Platinum Edition products. It is anticipated that the R520 will operate in the range of 600MHz-700MHz, which is much higher compared to today’s clock-speeds in the range of 500MHz. The chip known as RV530 is projected to serve performance-mainstream market and to be clocked at about 600MHz.
“The [R520] graphics chip runs extremely fast, and although we’re still finalizing clocks, I can tell you that we’re hitting stock engine speeds never seen before in this industry,” Mr. Orton said.
“Xbox 360-game console’s Xenos-graphics chipset was developed on 90nm with tremendous success, so we felt confident using it for the R5xx family. RV515, which will be aimed at the entry-level PC segment, also worked perfectly from the outset without encountering any manufacturing issues,” ATI’s chief indicated.
Even though the Xenos chip for Xbox and RV515 visual processing unit (VPU) for desktops are completely different from architectural standpoint – Xenos features 48 dynamically allocated Arithmetic Logic Units (ALUs) that can be used for both pixel and vertex operations, whereas the RV515 uses traditional pixel and vertex processors – they both operate at 450MHz – 500MHz, core-clock typical for today’s VPUs that are produced using 130nm or 110nm process technologies at TSMC.
ATI code-named R5-series of VPUs is projected to support Shader Model 3.0 and other innovations, which requires totally new graphics architecture from ATI. Among other improvements the flagship R520 product is expected to have over predecessors the head of ATI noted a brand-new memory controller.
ATI’s new breed of graphics processors – with yet-to-be-revealed brand-name – is expected to be formally introduced in late September or early October, 2005. Even though ATI has lost certain OEM contracts to NVIDIA Corp. and its GeForce 7800-series, the Markham, Ontario-based graphics company expects its new-gen products to be selling well in the retail and channel markets.

Just discovered R520 all electric circuits in the grid oxygen extremely ingredient appeared Al2O3, this thing one week ago or did not exist... Al2O3 has many fine characteristics. If high forbidden band band width (8. 9 eV), under high temperature with Si between very good thermostability, and can maintain crystalless under the traditional CMOS high temperature heat treatment condition. But its coefficient of dielectrical loss is quite small, approximately is 9. Therefore possibly only is one relative short-term emergency solution. But will compare K which 5 does not arrive to the present plan, Al2O3 as the HIGH-K appearance is the R520 frequency plays the extremely big 保驾 escort role. Believes future R520 frequency will can have very big enhancement, even is the leap... Except the frequency, reduces the leakage can give takes 填充层 cLow-K provides one clean electricity environment, subterranean puts on the leakage the reduction means 游离电子 the reduction, this enabled originally to worry 填充层 center because the electric current key value lowers occurs the home position proliferates the response causes LOW-K level deterioration ATI and the TSMC more or less loose one tone, after all is short one current supply ~ also is short one response possibility but the at present looks like the aluminum oxide joined regarding 24 32 R520 appearance does not even get up the obvious promoter action. Because that part of electric circuit by shutting down is because " is originally frail " or " soon is frail ", occurs with recycling R520 the home position will proliferate the response causes " the day after tomorrow to be frail " is different, at present the aluminum oxide also is unable to prevent " congenitally " the process occurrence. Entire HIGH-K the craft conformity truly some complex ~ basically whole affected TSMC the entire 90nm craft. How concrete does only then can join this thing in the craft I now does not know, but looks TSMC can so rapid also the complete realization, estimates wants difficulty not to be high, at best is allocated proportion question, the present craft can be compatible; Wants is has 高人 in the behind move, moreover the dynamics is very big... At present is engaged in below 90nm in the craft the aluminum oxide research only has INTEL.

Desengana-te pá, ainda tão eles a dizer mal do SLI já tão a levar com SLI2.0 na tola.

What about CrossFire solutions with more than two graphics slots?
"We can't comment on that, but SGI currently has an ATI-powered solution that fits that profile for vertical markets."
And with a stable, fast motherboard chipset now available from them, will we see a strong push into the workstation and power-user markets they've traditionally been a bit weak in?
"You are going to love me for this, but we can't comment on unannounced products."
Bah! Well, worth a go
sotavento disse:Dual Slot rulla ... não confundam dual slot com "dust busters".
quando implementarem uma solução single slot que remova o ar de dentro da caixa avisa aqui o ppl ... e a Nv e ATi tb já agora.

Rudzer disse:Julgas que a ATI vai implementar isto apenas para arrefecer as caixas dos users..afinal eles são santos né...
Grrr isso é a falar mal dos canadianos? ai ai im kiddingsotavento disse:??? são santos ??? na sei ... como são canadianos duvido ... LOL

Rumor do Ano
A intel ajudou a ati nas ultimas semanas, com tecnologia sobre o processo de fabrico de 90nm, que permite "estabilizar" o r520 a 700mhz e mais, resolvendo o problema de power leakeage.
