Asus P5K vs Asus P5K3 Benchmarks (DDR2 vs DDR3)

Conclusion

Conclusion

Since the release of DDR3 a short while ago, we've all been aware of the increased latencies surrounding this new technology. However, as the test results have proved today, a mediocre increase in memory speed (133mhz in this case) is all that's required to bring the high latency DDR3 modules up to and above the performance of DDR2 modules running at much tighter timings.

Of course, at the moment DDR3 modules are significantly more expensive than their DDR2 counterparts. This is more than likely to deter a large portion of enthusiasts from making the switch, but with more and more DDR3 motherboards entering the market and Intel's X38 chipset on the horizon, the price of DDR3 is bound to take a nosedive.

As for the P5K3 motherboard, not much has really changed from it's DDR2 based P5K twin brother. The layout of both boards is identical, meaning our previous praise for the P5K's layout and features is still valid. In addition to this, the P5K3 was also able to match the 520mhz FSB previously obtained by the P5K, and the maximum overclock on our E4300 CPU remained the same.

Both the P5K and P5K3 motherboards are available from the recommended retailers below for around £150. In addition to this, there is actually very little difference in price between the two boards, allowing you freely choose what memory platform to adopt without paying through the nose for the latest technology.

Tekheads


Pro's
• Clean and accessible layout.
• FSB speeds up to 520mhz (and beyond?).
• Improved heatpipe cooling system over the P5K.
• The higher latencies of DDR3 are easily overcome by a relatively small increase in Mhz.

Con's
• Despite the reasonable price of the motherboard, DDR3 prices are still very high.

"After reviewing the Asus P5K DDR2 based motherboard just over a month ago, we were left wondering how the DDR3 based P5K3 would compare. Today we're back with both boards in a head to head DDR2 vs DDR3 battle!"

looks the same as the ddr vs ddr2 when it came out too me...

Nice job jim.

I wasn't into pc's back then so I don't have any experience with ddr.

Is it safe to say that ddr2 now owns ddr in terms of performance?

I'm wondering if it is simply a matter of time before ddr3 really comes on with speeds of 2ghz and 5-5-5-15 timings and puts the nail in ddr2's coffin...

Nice work btw. I for one won't be buying a new mobo/ram until nehlam by the looks of this.

I was toying with getting another 2gb kit of cellshocks in the next month. Not sure what benefit I would get with 32bit XP pro... Hmmm.

Yeah pretty much, tho someone at OCZ told me that a Conroe on a DDR board beat the cr@p out of a DDR2 setup. Apparently it really liked the low latencies of DDR.

Deffo. Now they're tightening the timings of the DDR3 it'll soon be kicking DDR2's a$$ IMO.

I'm going to see if we can get hold of some of that Kingston 5-5-5-15 DDR3 and put it up against the 7-7-7-20 stuff and maybe some DDR2.

:eh: c2d and ddr beat c2d and ddr2?

Yeah those Kingston sticks look nice. Some company I haven't really heard of released some 1600mhz ddr3 the other day... CL10 though. Look

Apparently so...I wasn't quite sure whether to believe it either. I think it was running with timings of 2-2-2-something

They must had some seriously crazy test bed for that. Rather than just the ASRock 4coredual-vsta...
