The RV630 is going to be known as the Radeon X2600XT and PRO. Radeon X2600XT is going to end up clocked at 650MHz core and 1600MHz GDDR3 memory with 256MB memory and 64 Shaders. To our surprise the card only supports a 128-bit memory interface. It should cost around $200. This will be ATI's first 65 nanometre chip.
The Radeon X2600PRO will end up witha 550MHz core clock with 1400MHz GDDR3 memory and a 128-bit memory interface. The card also has 64 Shader units, so sixteen more than the R580 current high-end chip. It is priced at $150.
Radeons X2300XT, PRO and LE are RV610. The top-of-the-line Radeon X2300XT is clocked at 650MHz and has the memory ticking away at 1400MHz. The card uses GDDR3 memory with a 128-bit memory controller and has 32 Shader units. It is another 65 nanometre chip and the card will sell for $100.
Necxt up is the Radeon X2300PRO with 500MHz core and 1400MHz GDDR3 memory with 128-bit memory controller. It has 32 Shader units, 65 nanometre and the 256MB version will sell for $80 while the 128Mbyter should sell for $70.
The last in this DirectX 10 mainstream and low-end, unified Shader line-up is the Radeon X2300LE. This card will end up clocked at 500MHz core and 800MHz memory. It uses 128MB of 128-bit GDDR 2 memory and will have 32 Shader units. The chip is 65nm, very low power consuming and will sell for around $60. A Direct X 10 card for $60 sounds like a nice bargain for Vista.
There cards are expected to launch after around the beginning of May. µ
