I have two PC’s, an Athlon 2400+ system running DDR and a (until recently) Athlon 1800+ system running SDRAM. I upgraded the slower system to a new Athlon 64 (socket 754) 2800+ with DDR on a very nice board (DFI LanParty w/nforce3 250Gb chipset).
The problem is, according to PCMark04, my increase in speed is much smaller than I expected. Maybe my expectations were too high, but comparing the upgraded system’s CPU scores to the top 1800+ (1533Mhz) score on their online results browser shows only a 20-25% increase!
Unfortunately I didn’t run the mark on the old system. I did however run it on my other one (the 2400+) and it’s only a tiny bit slower. The CPU suite scores are:
2400+ = 3229
2800+ = 3396
The other suite's scores are similarly dissapointing.
What do I need to look for? The new system is clocking at 1810 Mhz, so that seems correct based on what I’ve read. Shouldn’t I be getting a much bigger speed boost over my old slow-ass system? It’s my HTPC and I wanted a big upgrade and figured the $300 I spent would be a good start.
