Memory tests and HEXUS.pifast
In SiSoft SANDRA's buffered benchmark, the two RS780G chipsets are better able to harness the potential bandwidth available, with higher scores despite running at slightly slower speeds compared to the Intel platform. Any extra bandwidth is likely to have a positive effect on performance when the IGPs siphon off a considerable portion of it.
Memory-access latency is rather surprising, with the Intel platform having a lower access time whilst the memory controller is further away, located on the northbridge, rather than integrated into the CPU like the AMD setups. This highlights just how much of a benefit Intel's advanced pre-fetchers can achieve.
Intel's Pentium Dual-Core E2180 is a little faster than the AMD Athlon X2 4850e in both the single-threaded HEXUS.PiFast number-crunching and dual-threaded WAV-encoding tests.
Across all benchmarks, the Gigabyte RS780G board's slight advantage over the Sapphire can be attributed to its marginally higher memory speeds.
