ScienceMark 2.0, Pifast
It's a tale of three cubes. The SN85G4 represents the finest from AMD. The Athlon 64 3200+ may only ring in at 2GHz but it has plenty of other attributes that have seen it smirk at the 3.2GHz Pentium 4. The ST61G4, powered by ATI's Radeon 9100 IGP, has decent onboard video but has shown to be left wanting in the tests with a discrete AGP card. Last but not least is the RefleXion itself. It's based on the i865G chipset and should have decent performance all around. ScienceMark 2.0 kicks us off.
Memory bandwidth analysis can provide a decent yardstick to measure other chipsets (based on the same platform) by. In that case, the RefleXion's lead over the like ST61G4 is significant enough to cause a large deviation between benchmarks that are driven by efficient memory throughput.
Latency is better on the RefleXion too. The SN85G4's sole CPU uses an on-die controller to wipe the floor with the Intel duo. The RefleXion is right about where we expect a non-PAT-enabled Springdale motherboard to be.
Yup. 63s is standard Springdale country. Springdale motherboards with a memory acceleration (PAT-like) BIOS usually hit the mid-61s mark. The poor ST61G4 doesn't have the bandwidth to count on here. A useful start. Decent bandwidth from a controller that's been around for a while.
