As we reported some time ago, NVIDIA plans to renew its graphics product lineup this Fall in order to compete with the rival ATI Technologies more effectively. The NV31 is reportedly to be replaced with the product code-named NV36 that seems to be based on the GeForce FX 5900 aka NV35 technology.
The new graphics processor for performance mainstream and mainstream segments is expected to be a bit more powerful compared to the predecessor and will surely bring the new level of speed into the market at its price-point, an NVIDIA PR agents would have tell you. Things about NV36 that are not supposed to be told by marketing people are the following:
- Number of transistors: 82 million;
- Rendering pipelines: 4;
- Core-clock: Roughly 500MHz;
- Memory clock: Around 325MHz;
- Memory bus: 256-bit;
- Initial tape-out: May 2003;
The graphics chip is expected to be made using IBM’s 0.13 micron fabrication process in
I think the chip will be more powerful compared to the NV31 in calculating Pixel Shaders, just like the GeForce FX 5900 is more powerful compared to the 5800 when operating in 32-bit FP mode. I also believe that the NV36 – dubbed NVIDIA GeForce FX 5700 – will be hugely more powerful compared to the predecessor in FSAA modes thanks to wide 256-bit bus and increased core-clock.
The GeForce FX 5700 will definitely be faster compared to the RADEON 9600 PRO as well, especially in situations when memory bandwidth is stressed hugely, so, ATI will have to boost the upcoming code-named RV360 processor somehow. Excellent Pixel Shader 2.0 speed on the RADEON 9600 PRO is not supposed to be surpassed by the GeForce FX 5700, though.
Keep in mind that since it takes about 14 weeks to re-spin a 0.13 micron chip, the GeForce FX 5700 may start to appear in September, in case only one re-spin is required. If the situation is unfavorable for NVIDIA, expect the GeForce FX 5700 to show up in late Fall.
