Radeon 9250 je RV280 arhitektura i DX9, a ne DX 8.1 grafička. Dakle, 9250 bi trebala zadovoljavat minimalne uvjete za pokretanje aera..

"The Radeon 9000 (RV250) was launched alongside the 9700 (the new flagship part for ATI). This chip dropped one of the two texture units, the "TruForm" unit, Hierarchical-Z, and one of the two vertex units, bringing the configuration down to a 4x1 pixel/texture pipeline layout. It was not just cut down, however, but was actually refined as well. The texture cache was doubled in size to 4 KiB, improving a serious inefficiency in R200. Because of this, performance was still quite competitive, considering that the "R200" chips were more expensive and much larger and power consuming. In games, it performed around the same as the highly-refined "NV17" used on GeForce 4MX440. Its main advantage over the GeForce4 MX440 was that it had a full DirectX 8.1 vertex and pixel shader implementation. The Radeon 9000 replaced the uncompetitive Radeon 7500 (RV200) in the mainstream market segment.
A later version of the 9000 was the 9200 (RV280), which, aside from supporting AGP-8X, was identical. However, there was a cheaper version, the 9200SE, which only had a 64-bit memory bus. Another board, called the Radeon 9250, launched in summer 2004. It was simply a lower-clocked variant of Radeon 9200. It, in fact, used the same "RV280" GPU. It was usually equipped with more RAM than the Radeon 9200 cards though (128 MiB or even 256 MiB), taking advantage of the low-cost of slow-clock high-density DDR SDRAM, a popular trend at the time."
