Word from the Inquirer has it that NVIDIA's upcoming 8500GT (their next-gen low-end card to take over the reigns from the current 7300 series) will use a 128-bit memory controller which is what AMD's equivilent X1300 series has. NVIDIA's 7300 cards were crippled performance wise due to a piddly 64-bit controller.
NVIDIA MUCKED UP with its 7300 series. Creating a GPU with a 64-bit memory controller only meant performance was constrained compared to the AMD's Radeon X1300 offering. Even though Nvidia currently owns high-end segment with the excellent GeForce 8800 series, the low-end segment makes most revenue for all companies and here is where this current line-up faltered.
