Radeon 9550
RADEON 9550 was intended to compete with NVIDIA GeForce FX 5600XT/5200. The released R420/NV40 had one bad quality in common - the highest price. And therefore, at first, they were obviously doomed to a meager demand in the amount of 2-5% of all sales. And that's why the eyes of an ordinary user, which flared up from the sweet speeches of ATI and NVIDIA representatives about the release of super-accelerators, quickly faded after reading the amounts in monetary terms that these 3D business sharks wanted for their products.
Still, mass demand is where you can pay no more than 100-150 US dollars for a video card. And even less. But in the Low-End segment, ATI didn't have anything at all capable of supporting DirectX 9.0.
And the idea came up - to collect waste from 9600, that is, chips that did not pass the test at 325 MHz. Well, and, in part, normal 9600s could also go to this sector, just with reduced frequencies in a willful manner. Thus, we got the same 9600, but operating at lower frequencies.

These cards were a good solution for enthusiasts, allowing you to achieve the performance of older cards when overclocking.
