ATI R600 Rumor Mill
The Rumor Mill is working hard over at The Inquirer as they report that ATI's next-generation R600 GPU faced yet another bug which helped attribute to the lengthy delay to market. Aside from the initial bug which locked core frequencies at a ceiling of 500MHz, the second issue found disabled Multi-Sampled Anti-Aliasing (MSAA). Regardless, A1-variants of the core will have at least one of the major bugs ironed-out with a likely A2-stepping being the version which will be released to market and (ideally) bug-free. In either case, some new information is also making itself known with regards to the R600 architecture. Supposedly, the RingBus configuration remains though the external memory controller is now a true 512-bit design. In addition, rumors suggest we'll see 16 ROP's as well as 64 SIMD shader units. One thing is certain, it will be interesting to see how ATI's approach to DX10 will compare with NVIDIA's newly released GeForce 8800 series of GPU's.
