In summary it has:

4 pixel shaders processors;
2 vertex shaders processors;
2 texture units;
2 render back-end units;
4 z compare units.

Models

Theoretically all Radeon X1300 models should reach the market today. Three models were announced: Radeon X1300 Pro, Radeon X1300 and Radeon X1300 HyperMemory. Also, a sub-25 W low profile version was mentioned, but we still don’t know where this model fits. The main features for these chips are shown on the table below.

Availability

Radeon X1300 Pro 600 MHz 800 MHz USD 149 (256 MB) Oct 05th, 2005

Radeon X1300 450 MHz 500 MHz USD 99 (128 MB) and USD 129 (256 MB) Oct 05th, 2005

Radeon X1300 H.M. 450 MHz 1 GHz USD 79 (32 MB) Oct 05th, 2005

HyperMemory simulates a 128 MB video card by using 96 MB of the system’s RAM memory as video memory. Read our tutorial on HyperMemory for more information on this subject. Even tough Radeon X1300 HyperMemory has only 32 MB on-board, it accesses its memory at 1 GHz, double the speed of the plain Radeon X1300, in order to compensate the difference in video memory size. Interesting.
