ScienceMark 2.0, Pifast
2GHz clock speed, 1MB of L2 cache and an on-die memory controller will all conspire to make this one of the very fastest XPCs yet. Let's see what ScienceMark 2.0 thinks.
Single-channel chipsets will always be at a disadvantage in this test. However, the SN85G4 does remarkably well for a DRAM controller that can only output a theoretical 3.2GB/s. It manages to eclipse the VIA K8T800 with a few MB/s to spare.
Memory latency is equally outstanding here, and the 51ns penalty is the lowest we've seen off CPU cache. Compare that with the 94 clocks of the dual-channel nForce2 Ultra 400 chipset. It bodes well for performance. Please remember that the Athlon 64 3200+ runs at 2GHz; 200MHz slower than both the FX-51 and XP3200+ Barton.
Pifast seems to like it. The resident constant calculator loves sheer MHz and lots and lots of low latency bandwidth. Whilst the SN85G4's fastest compliant CPU is at only 2GHz the performance is admirable.
