DDR5 Memory Boosts Intel Raptor Lake Performance by up to 20% Compared to DDR4
As we approach the launch of Intel's upcoming Raptor Lake desktop processors, we are getting more leaks of testing performed by system integrators and 3rd parties that have early access to the engineering sample (ES) chips. A few days ago, we saw an Intel Core i7-13700K CPU run Geekbench 5 benchmark with the older DDR4 memory on ASRock Z690 Steel Legend WiFi 6E. Today, we are seeing a similar test performed on the same processor, with ASRock Z690 Steel Legend WiFi 6E/D5 equipped with DDR5 memory. While the previous DDR4 testing used modules running at 3200 MT/s, the DDR5 testing uses 5200 MT/s rated DRAM with unknown timings and setup.
As far as performance goes, the single-core result of the 16-core Intel Core i7-13700K processor was 2090 points with DDR4, while DDR5 showed a slight regression of 2069 points. Of course, this could be attributed to the margin of error. As far as multi-core performance goes, the DDR4 testing managed to produce 16542 points, whereas the DDR5-equipped platform scored 19811 points. This is an immediate 20% performance uplift in multi-core score. It shows that all the cores present in Raptor Lake processors are starving for bandwidth, and a faster memory protocol can bring quite an improvement. As usual, we have to wait to confirm this information with our testing so that we can draw more conclusions.

It must be said that 3200 DDR4 is the lower bandwidth end of DDR4 you can get 4000/5000+ DDR4 kits today. that may close the some of the gap/performance to DDR5.
These PR stunt never stops
Great for productivity talks, for gaming not really. Yet. ;)
I can buy a 4400 ddr4 but that’s one way transfer speed while a similar ddr5 is two way at the same speed.
Where ram speed matters alder/raptor lake and zen 5 will be destroying all our am4 setups.
I think the people with 690 DDR 5 boards are certainly going to see the best of Raptor Lake.
How much bandwidth did the CPU need to get that extra 20% performance in MT and could the same performance be possible with higher bandwidth DDR4 kits?
This can only be answered once additional tests are carried out.
We still dont know how much bandwidth starts bringing diminishing returns in performance. Overall quiet happy to see DDR5 shaping up to be much faster than DDR4
or maybe I should say New CPUs being able to make better use of higher memory bandwidths offered by DDR5.
Prices are acutally not too bad for 32GB DDR5 kits locally but still needs to come down more to become mainstream.
Anyway, seem that ddr4 "clock" just made another push towards obsolete state
I'd say both (sc/mc) resuslts are within the margin of error, the multi-core score is barely over it.
We did see similar things with Skylake back then.
For now I'm satisfied with my i7 12700K though, but a Raptor Lake CPU can be my last upgrade on Z690.
ddr5 latency off the charts but that is just a small detail same as ddr4 3200 verse 5200 is trivial and not worth questioning :laugh:
Just part of the regular cycle of tech that EOL is the, well, the end of it ;)
I'd think you'd be more interested in another gpu at this point instead of another cpu.
Ram, bam, thank ya Ma'am, hehehe :D
