Compared to ATI Technologies' R520 ASIC, there are significant differences in how its new R580 goes about the business of data processing. Be under no illusions - R580 ain't no simple R520 speed bump... Quote:R580, moreso than any modern GPU that meets the D3D9 spec, therefore relies on software to show it off. Even current synthetic benchmarks designed to show off theoretical rates in 3D hardware can have a hard time exploiting the tripling in fragment processing ability. That's not to say the performance increases at the same clocks as R520 are invisible. Clearly they're not without increases, especially at the higher resolutions, of up to 30% in the games we tested, clock-for-clock.
