Some interesting info from an investor meeting held with ATI's CEO Dave Ortonon August 17th :
• Late September Launch Date Set for Three R500 Desktop Discrete Chips (R520,RV530, and RV515)
• The shipment dates will likely be staggered for the three chips, based on thedelivery cycles from TSMC, with one likely shipping at launch date and the othertwo within the first half of October
• R520 had been sampling since Dec/04, and although the architecture and 90nmprocess were not a problem, ATI was not able to run the clock fast enough due toa “soft ground” issue that was discovered in late July after debugging withseveral re-spins.
• R520 and RV530 had functional yields, but could not run at high speeds, whilethe RV515 and the C1 (the 90nm Xbox graphics chip) did not have any issues.
• In terms of performance, ATI believes the R520 should exceed the GeForce 7800GTX in benchmark tests if it can get the proper clock speed, but recognizes thatNVIDIA has some headroom to overclock the GeForce 7800 clock speeds.
• ATI unlikely to launch its R580 (speculated to have 32 pixel pipelines) inC2005 and expect a refresh of the R500 family beginning in spring 2006 withRV560, followed by RV540 and RV505.
• R600 targeted for (DirectX 10, targeting Vista and WGF 2.0) in Q4/F06 orQ1/F07
