Memory Performance
Along with the processor, performance of the memory is what defines the basics of a mainboard platform and how it performs. We start by seeing how much bandwidth is available from memory controller to CPU and how quickly the CPU can get access to that bandwidth.Bandwidth
The bandwidth available to the CPU via the RD400X and memory modules on the PA1 MVP Extreme is slightly less than the comparison platform, the ECS board posting a deficit of around 8%. However if an application isn't bandwidth starved the difference won't be manifest and that's often the case on the P4 platform.
Latency
When made to go out to system memory for a memory access, the MVP Extreme is ever so slightly slower than the ABIT board on average, although the difference is less than 1%. Memory subsystem performance is therefore competitive on the PA1. Validation comes in the form of our very own HEXUS Pifast test.
HEXUS Pifast
The PA1 is competitive, only 2% slower than the i955X-based AW8-MAX.
