Our friends at HKEPC Hardware have gotten themselves a ATi Radeon R520XT ES Sample card.
Comparing the ATI R520 Rev 2 card against the previous generation Radeon X850XT PE, we can observe that the PCB is longer at 229mm similar to GeForce 7800GTX. According to our source, the R520 core is design with 32 pipelines in mind but due to yield problem, not all the pipelines can be utilized. We expect R520 will have 16pp, 24pp and 32pp versions using 90nm micron process technology from TSMC. Die size is at 16mm x 18mm and will support Shader Model 3.0 and Direct X 9.0c. According to our source, the R520XT sample will be clocked at 650Mhz core and support 512bit Memory internal bus but only 256biy controller.
