In a bid to take on the threat from Nvidia’s new GeForce GTX 285, the rumour mill reports that AMD is planning to release a new single-GPU graphics card in April called the Radeon HD 4890.
Tech gossip site VR-Zone claims to have spoken to a source with a sample of the GPU, who says that it will be based on the RV790 core, and will feature a core clock speed of 850MHz and a GDDR5 memory clock speed of 975MHz (3.9GHz effective).
The site also reports that two versions of the GPU will be released as standard – a standard edition and an overclocked edition. The former is apparently due to be released in mid April, with the latter arriving in a future month.
