Nvidia G70 is a 90 nanometre chip

NVIDIA COULD not contain all the information about G70 forever and we finally found a way to learn some more about it.

It turns out that the G70, also known as the Geforce series 7, is going to be a very similar chip to the just announced Playstation 3 chip. We wrote about this here. Nvidia is still keeping quiet about the final spec of the chip but we know it's a 90 nanometre chip and that it's likely that it will have at least 10MB of cache memory. ATI's Xbox 360 chip has exactly the same 10MB as you need to have enough buffer to render HDTV picture quality games. That's what the new consoles are all about.

We also learned that the G70 is getting ready and that Nvidia is just a month or so away from releasing the chip. We expect that the G70 won't have 10MB of cache like its Playstation chip brother, as this is just too expensive to make at this point. ATI also has two version of the next generation chip - one called R520 for graphic cards and second codenamed R500 is Xbox 360 chip, very similar to the R520 but powered with 10MB of Edram cache memory.

The Playstation 3 chip runs at 550MHz and this can give you at least some idea about Nvidia's G70 clocks.

Stay tuned, as we believe that we can dig out even more information about this chip here at the show. µ
