Graphics cards based on AMD's mid-range Radeon HD 2600, and entry-level HD 2400 will hit the market on June 28 after a delay of more than a month, according to sources at graphics cards makers.
AMD had originally been expected to launch cards with the DirectX 10-supporting HD 2600 and HD 2400 in May, but now their launch will come more than two months later than Nvidia's G84 and G86, the sources indicated.
But the sources commented that despite Nvidia's head-start, the delay in AMD's launch of the entry-level and mid-range GPUs is unlikely to have a serious impact on its fight for the DirectX 10 market, because DirectX 10 works only on Vista, whose demand has yet to pick up.
AMD on June 11 already announced that it had started shipping the two new GPUs to its add-in board (AIB ) customers.
The HD 2600 is manufactured by Taiwan Semiconductor Manufacturing Company (TSMC) using a 65nm process. It will have three different versions: the HD 2600XT which adopts GDDR4, the HD 2600XT which adopts GDDR3, and the HD 2600PRO which features a lower clock speed.
The HD 2400, which features a 64Bit memory interface, is also manufactured by TSMC using a 65nm process. It comes in two versions, the HD 2400PRO and HD 2400.
Although using a 65nm process may give AMD an advantage in costs and clock speed over Nvidia's G84 and G85, which use an 80nm process, the sources pointed out that because AMD is at its initial stage of production at 65nm, it remains to be seen whether the yields can meet its expectations.
