Texture fillrate performance in GTexels/s
AMD Radeon RX 7900 XT 2,074
ATI Radeon X1550 2

The difference is 103600%.

The term texture fillrate refers to the number of map texture elements (texels) that the GPU is capable of generating per second. This performance is achieved by multiplying the texture mapping units (TMUs) by the clock frequency of the graphics processor unit.
