Isto e, está claro, poder usar o bus do PCI Express como um tipo de SLI para poder usar mais do que uma placa gráfica em paralelo, a acelerar o mesmo ambiente 3D

Não sei se será bem dream mode.. Já há imensa gente (developers, sites de hardware etc.) a comentar isso desde que o PCI Express veio à baila.

O problema é, que board vai ter duas pci Ex 16X?
Não estou a ver uma grafica numa 16X e outra numa normal.
Duas 16X até deve ser possivel, mas não havendo mercado sera que algum fabricante vai apostar nisso?
E sim, eu tb gostava que o SLI voltasse.
Edit: O que é que o AGP ou Pci Ex tem a haver com a comunicação entre os dois gpu's da volari? Aquilo não é um bus interno na placa?
http://www.digit-life.com/articles2/volari-duo/index.htmlObviously, dual-processing is based on the old principle of master and save processors. They have a special internal bus between them marked as X-Link (also known as BitFluent). This is actually the internal AGP2x, 32 bits wide and working at 133 MHz. The processors work similarly to those in the ATI RAGE MAXX - everyone renders its own frame, but unlike to ATI's product, the chips do not wait for each other to sync when rendering is completed. The disadvantage is a low throughput of the internal bus which transfers data from applications and the slave processor which also constantly reports its results to the master one. Besides, in such configuration most data duplicate in both memory buffers, and each chips fulfills caching separately and less efficiently compared to one chip with the 256bit memory bus.

Penso que já foram soluções mais do que tentadas, falharam todas. Só o grau de complexidade para meter 2 VPU's a trabalhar em conjunto é enorme.
Eu penso que VPU's separados é uma perda de tempo, agora VPU's dual ou quad core, isso sim, tem mais vantagens.

Já se anda a falar há algum tempo de boards com mais de um PCI Ex 16x justamente para albergar mais que uma placa gráfica.

O bus interno da Volari, tambem conhecido como BitFluent, não é mais que um bus totalmente equivalente ao AGP2x (enganei-me, tinha dito 4x e afinal é 2x.. ainda pior..), ou seja, 32bits a 133Mhz.

Discordo. O SLI da 3dfx foi um sucesso como eficiencia de arquitectura. Na voodoo2 os resultados obtidos quando se ligavam 2 voodoo2 em simultâneo eram excelentes, e a Voodoo5 só foi um fracasso porque chegou demasiado tarde e não tinha T&L.
“We’re excited to showcase a new class of software tools designed to empower developers to take advantage of the latest advancements in graphics hardware, such as Shader Model 3.0,” said Mark Daly, vice president of content development at NVIDIA. “NVIDIA’s tight integration with the game development community ensures that we're able to consistently deliver the caliber of technologies that address the needs of an evolving game industry."
Shader Model 3.0 enables developers to achieve a class of film-quality effects never before possible in real-time game rendering. NVIDIA's native support for this technology advancement in its next-generation hardware platform presents an exciting opportunity for developers, as it allows for the adoption of more flexible and natural programming methods. The results will yield a higher caliber of visually stunning games with distinct improvements in materials, lighting, and scene complexity that mirror real-world situations.
Throughout the week NVIDIA’s technical experts will lead a series of technical sessions focusing on tips and tricks for real-time graphics that can be adopted to create a new generation of visually stunning gaming experiences. A sample of NVIDIA-led sessions include the “Next Gen Special Effects Showcase,” “Cinematic Effects II: The Revenge,” and “Tools to Squeeze Maximum Performance from your GPU.” The Company will also host a jam-packed line-up of booth activities, which includes daily presentations from the industry’s top developers and digital content creation providers, including Epic Games and Alias, who will demonstrate their latest projects and achievements.
