Memory Benchmarks

Our usual set of memory tests to get a bearing on the Time's initial performance. Slightly lax timings and DDR333 will put it at an immediate disadvantage compared to the K8V reference box, the question being by how much. Pifast first.

Pifast

Pifast gives us an initial insight into memory performance and we can immediately see what we postulated above. Sciencemark helps us confirm why.

Sciencemark Latency

5ns of extra latency when fetching data from main memory, compared to the DDR400 + low latency enjoyed by the ASUS K8V, means the CPU can't read or write data as fast as it really should, to or from main memory. That doesn't help when you've also got less bandwidth to play with.

Sciencemark Bandwidth

A single DDR333 channel rears its head, suboptimal when the memory controller on the CPU is able to run at DDR400 without a problem.

But, as Pifast shows, the CPU does its level best to smooth out those bumps; there's no huge gaping chasm between the two in terms of performance. That must mean the CPU-level performance is spot on. Let's check.
