ATI X1950 "Xenos" is not even close to a 4770. At all. The Radeon HD 4700 series completely owns the X1000 series. The 4700 series is about 800% better at graphics rendering. It's not even a contest.

By specs 200-250% better.

R500 (XENOS): 240 shaders units, 16 textures units, 8 render units,  4 GPixel/s, 12 GTextel/s, 22.4 GB/s
RV740 (HD 4470): 640 shaders units, 32 textures units, 16 render units,  8 GPixel/s,  24 GTextel/s, 51.2 GB/s

But the XENOS have the eDRAM at 256GB/s with 192 parallel pixel processors + hardware optimized DirectX.

In real games the power of the HD 4770 is less then 200% bigger than XENOS (and the eDRAM further reduce the gap).
