ll but two.
That's how many benchmarks in which our 1GHz/1.2GHz (core/mem) Radeon HD 4890 lead the stock NVIDIA GeForce GTX 285. That's nothing to sneeze at. Certainly it doesn't mean that the 4890 is faster or better than the GTX 285, especially because the GTX 285 can be overclocked as well to improve performance. What this does mean is that for about $100 less we have the potential to achieve the stock performance of NVIDIA's flagship single GPU part with a highly overclocked AMD GPU. From an end user value perspective, that extra $100 is there to ensure you get at least the performance of the GTX 285 along with any potential overclocking benefits you might have from the higher end part. There is still reason to buy the GTX 285 if you need even more power. But this is quite intriguing from an architectural perspective.
These tests show that there is the potential for a 959 Million transistor AMD GPU to consistently outperform a 1.4 Billion transistor NVIDIA GPU in the same power envelope at 55nm with similar memory bandwidth.
