Intel DDR2 FB-DIMM Performance
For a comparison against traditional desktop DDR2, we also tested another setup using non-Registered non-ECC DDR2-667. The base of this system was a Tyan Tiger i7230A S5160. This motherboard is powered by the E7230 Mukilteo Chipset and ICH7R. For keeping this a desktop system, an Intel Pentium 4 530 was used with Hyper-Threading and comes clocked at 3.00GHz with 2MB of L2 cache.
Finally, for a bit of a legacy look at things, we also pulled out an aging Intel Socket 478 system with DDR-400 memory. The basis of this system was an Abit SG-72, which is powered by the SiS 661FX + 964L. The processor uses a Prescott core with 800MHz FSB and DDR-400 memory.
To focus on the memory performance differences we turned to RAMspeed, which has proved repeatedly at Phoronix to be one of the best Linux memory benchmarks. Rather than using our usual tests of running RAMspeed 5 or 10 times to average the results, to ensure further accuracy, each of the RAMspeed tests were ran 20 times. Both integer and floating point memory performance was monitored with all of these systems. These test can be replicated with ramspeed -b 3 -l 20 and ramspeed -b 6 -l 20. The lastest version of RAMspeed at this time is v2.4.1. On the next three pages are these results.
