Radeon X1300 PRO is an entry-level GPU based on the 80nm variant of the R500 architecture.
It's based on the RV516 Core and offers 4 Pixel Shaders, 4 TMUs and 4 ROPs, on a 128-bit of standard DDR. The central unit runs at 600MHz and the memory clock operates at up to 400MHz.
Radeon X1300 PRO offers higher clock frequencies than Radeon X1300 but it also consumes relatively more power. Its performance is relatively better than X1300 but today's modern games are still only playable at the lowest settings or unplayable at all. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
