Even though ATI RD482 chipset Crossfire boards are just appearing in the market, ATI is already far along in the development of their next chipset, called ATI RD580. We recently had an opportunity to spend two days testing the new RD580 Crossfire motherboard, code-named Manta, and to directly compare the RD580 Dual X16 chipset with the recently reviewed Asus A8N32-SLI Deluxe featuring the nVidia Dual x16 chipset. The comparison included both single and dual video card head-to-head testing with 7800GTX SLI (running 81.87 drivers) and X1800XT Crossfire (running Catalyst 5.11). Because X1800XT Crossfire and The RD580 chipset have not yet officially launched, ATI has asked that we not publish hard benchmarks of our results, since they will likely change in final release versions. We can, however, talk in general terms about performance. Those of you who believe ATI is far behind nVidia are in for a surprise.
