Sources from around the web have coalesced over the last few days to paint an unconfirmed picture of what NVIDIA’s upcoming GeForce GTX 400 series will offer the GPU market.
First, according to leaked marketing slides coming out of donanimhaber.com, we have confirmation of the GTX 480’s length, memory bandwidth, memory bus width, power consumption and connectivity. The site also revealed a picture of what is alleged to be the first retail GTX 480 design captured to date.
Next, legwork conducted by the same site has revealed official core/shader/memory quantities for the GTX 480 and GTX 470, as well as the number of stream processors, the latter of which has been a point of considerable dispute and speculation in the industry.
GeForce GTX 480
Stream Processors: 480
GPU Clock: 700MHz
Shader Clock: 1401MHz
Memory: 1536MB
Memory Clock: 1848MHz
Bus width: 384-bit
These figures fall short of what NVIDIA has been touting for nearly a year, as the company has maintained for nearly a year that the top-end GF100 chip would have 512 stream processors. Core, shader and memory clocks, too, were alleged to have higher targets.
It is widely believed that the GF100 chip is big and hot, which can easily be inferred from the die shots that have leaked around the web. Runaway thermals and power consumption can easily sabotage optimistic goals for a GPU’s final clockspeeds.
GeForce GTX 470
Stream Processors: 448
GPU Clock: 607MHz
Shader Clock: 1215MHz
Memory: 1280MB
Memory Clock: 1674MHz
Bus width: 320-bit
Final thoughts
Even though the information presented here is incredibly probable, it needs to be reinforced that nothing has been confirmed. We’ll have to wait until March 26 for the real answers.
