The possible introduction of ATI Radeon HD 2900 XT graphics cards with 1GB of GDDR4 memory onboard has been discussed for several weeks with some even referring to it as to ATI Radeon HD 2900 XTX product, which AMD kept in its pocket to launch at a time it needs to compete against its rival Nvidia Corp. with something more advanced than currently shipping Radeon HD 2900 XT 512MB.
However, Advanced Micro Devices has decided not to officially unveil higher-speed graphics card with 1GB of memory, possibly due to the lack of interest in picking up GPUs capable of operating at clock-speed higher than 742MHz, a costly task that may still not allow the company to capture a significant market share.
It is unclear whether AMD plans to introduce ATI Radeon HD 2900 XL or Pro versions based on graphics processors with disabled execution units or with lowered clock-speeds.
