Rightmark Latency

I think the elves at AMD have expended most of their effort on reducing latency.

There is no other possible explanation for the unbelievably low DDR2 latency figures Rightmark is reporting. The performance is nothing less than spectacular.

The AM2 5000+ stock and AM2 3800+ stock (and of course AM2 overclocked) even beat the stock FX-60!

Granted, the overclocked FX-60 takes second place, ahead of the stock AM2 5000+ - but given the higher latencies of DDR2 vs. DDR, it is an unbelievable showing for the AM2. I won't even put percentages on it. Look at the chart. Enough said.

Rightmark Bandwidth

Given the excellent results the AM2 got in the read, write and latency benchmark, the results of the bandwidth benchmark were a bit surprising. Not that the AM2 does badly - it still beets the FX-60 and the X2 3800+, although the overclocked FX-60 does well too.

But the more mature 975 chipset used with the D 930 (stock and very overclocked) dominated this benchmark.

My guess? The "turn-around" cycle times were hurting the AM2. I am sure future silicon revisions will fix this. All in all, DDR2 still beat DDR.
