*Re: they used an old BIOS that is known to have compatibility problems with the specific graphic configuration they chose** Are you talking about "Fix Fill 3114 SVID&SSID"? It has nothing to do with graphics but with the SATA controller according to the post below at Ace's. I assume 3114 refers to the Silicon Image SiI3114 SATA controller. SVID = Subsystem Vendor ID. SSID = Subsystem ID. A problem with the SATA controller's SSID/SVID is not going to result in a performance loss on a graphics test. Sounds to me like this guy doesn't know what he's talking about. aceshardware.com * the memory bandwidth performance lagged behind other published results Somewhere around 5-8% which I readily admit would impact AMD performance. Even assuming the 5-8% bandwidth performance leads to a 5-8% performance increase in every benchmark, which isn't realistic, the Athlon still got slaughtered. * since the CPU was not recognized it is highly likely that the temperature of the CPU was not measured correctly, since each stepping has its own thermistor characteristics and its own algorithm for transitioning between p-states. This might have led to the CPU frequency being reduced by a notch or two during operation. Thermal throttling on Athlon 64? I better add that one to my list of far-fetched explanations. :) * the ATI drivers used obviously did have specially coded paths for the Conroe, otherwise they would not have been used. No respectable site should allow this without doing a regression test to determine if the driver is capable of handling ALL games and not just the few that were chosen by Intel. It's easy for a driver to optimize for a few benchmarks if it doesn't have to handle all the special timing and sequencing cases of general operation. An ATI driver specifically meant to only speed up performance on F.E.A.R., HL2-Lost Coast, Quake 4 and UT2K4 with Conroe, but not on the AMD system? Riiiight. I suppose AMD should be suing ATI for conspiring with the monopolistic Intel to unfairly improve pre-production benchmarks. If there were specific Conroe optimizations that applied to all games and ATI mananged to get them working this early, I'd say thumbs up to Intel/ATI. More than likely the changes were due to compability issues to make sure the dual-core optimized ATI drivers can also recognize Conroe as a valid dual-core CPU, or to address issues specific to the motherboard/chipset. Tuned video card drivers won't help the lower clocked Conroe beat the Athlon in the encoding benchmarks either.
