标题: Dave Orton promises R600 to feature "new levels" of bandwidth
http://www.beyond3d.com/#news36695

Speaking at yesterday's AMD Financial Analysts Day, Executive Vice President of Visual and Media Businesses, Dave Orton, appeared to throw down the performance gauntlet in favor of AMD's upcoming R600 GPU. Having had over a month to study NVIDIA's G80, Orton did not seem the least bit intimidated. In a slide entitled "R600: Why we lead in graphics", Orton promised that even if the name of the company had changed, that the commitment to GPU performance leadership had not. He promised a "take no prisoners" approach to performance leadership for AMD's new GPU.

More interestingly, in his verbal remarks Orton reported (at roughly the 1:22:30 mark of the webcast) that one of R600's key advantages would be "new levels of memory bandwidth to the graphics subsystem, and bandwidth is critical to graphics performance." As all graphics geeks know, AMD pioneered the move to GDDR4 memory with the Radeon X1950 XTX, which gave them a temporary advantage in bandwidth. However, in the period since NVIDIA has released the 384-bit GeForce 8800 GTX, whose memory bandwidth crushes the X1950 XTX by 86.4GB/s to 64.0GB/s. It is impossible that AMD could regain a significant enough advantage in bandwidth to be cited by Orton as a major competitive advantage without following NVIDIA north of the 256-bit bus that has been a mainstay of the ATI/AMD high-end products since 2002's Radeon 9700 Pro.

As such, Beyond3D now believes that the persistent rumours that R600 will feature a 512-bit bus to graphics memory are most likely true, and at any rate believes that R600 must feature an external bus greater than 256-bit in order to back up the smack AMD's Executive Vice President laid down.

In other tidbits, Orton also vowed to be first to the 65nm technology process, but did not disclose which product he had in mind for the honor, nor even product type, GPU or chipset. Our graphics-oriented notes (and a few selected slides) on the rest of the conference are included inside, if you dare to take the red pill.

Dave Orton, Visual and Media Businesses

UVD (Universal Video Decode) aimed at BRD/HD DVD. "Critical" for value platforms.
"About half" of the 2,500 engineers of former ATI are software engineers. On the consumer side its a little higher.
Vista driver work with Microsoft began in 2003.
"Take no prisoners" performance approach key at the top. Slide title "R600: Why we lead in graphics". Key advantage is second generation of Unified shaders.
"New levels of memory bandwidth to the graphics subystem, and bandwidth is critical to graphics performance."
Buzz phrase alert! "Dynamic Game Computing" will provide new levels of visual realism.
Process technology leadership will continue. "We will be the first in the market to bring high performance 65nm as well"
R600 technology will be driven down market.
"There have been questions about what's our commitment to the GPU market as a company?". They consider the gaming market and technologies to be critical so that high-end tech can be leveraged down market.
Vista can grow GPU market, including business market. (yeah, yeah, heard it all before --time to prove it)
Expects the AMD sales team to help significantly in selling workstation GPUs in enterprise market.
Unified software stack with AMD will help in business/notebook markets.
GPGPU opportunity just beginning.
Fusion in 2009: Mainstream (both notebook and desktop), Portables, Emerging markets.
3D technology "waterfalls" from high-end to low-end, but must be reengineered on the way to a degree to get die size and power reqs down. Former ATI has good experience with this from the Consumer business.
Multimedia: UVD in integrated and low-end provides value.
H.264 coming to AMD cell phones.
Fusion helps make new convergence segments possible. Fundamental for performance, cost and power.
GPUs are the core of the business (presumably of his division), and "the opportunity to put that business back on track in the gross margins area".
Shared vision of convergence of PC and consumer area in 2009+ time-frame was the real driver of the AMD/ATI merger.

“第二代联合渲染引擎”，请问AMD的第一代在哪呢？

请问 XBOX 360 您听说过么？

Xenos.

Alstrong: When he says "second gen unified shaders" does he mean Xenos is 1st gen and R600 is second?
Dave Baumann: Yes.
