Intel Raptor Lake finally makes DDR5 memory worth it

The upcoming Intel Raptor Lake processors will support both DDR4 and DDR5 memory, but it seems that the 13th generation Intel CPUs may finally convince many users to switch to DDR5.

In a new benchmark, the Core i7-13700K was tested with DDR4 and DDR5 RAM. The latter really let it shine and delivered a huge improvement in multicore performance.


The benchmarked processor is Intel’s next-gen Core i7-13700K, which comes with 16 cores (eight Raptor Cove performance cores and eight Gracemont efficient cores) and 30MB of L3 cache. The base clock is rumored to be 3.4GHz with a boost to 5.3GHz. Although the chip was already spotted in previous benchmarks in combination with DDR4 RAM, today’s leak was first found by Bank Leaksshows DDR5 unlocking its true potential.

In the tests, the Core i7-13700K was mated to an ASRock Z690 Steel Legend Wi-Fi 6E motherboard for the DDR4 option, while the DDR5 system had the D5 version of that same motherboard. The only difference between the two cards lies in their memory slots. The tester used DDR4-3200 memory for the DDR4 test and DDR5-5200 for the DDR5 benchmark, the native memory supported by Raptor Lake. Both systems had a total of 32 GB of RAM, which equates to two sticks of 16 GB each. However, the benchmark does not reveal the timing or exact model of RAM used.

Now let’s take a look at the scores each system was able to achieve. The DDR4 platform managed to score 2,090 points in single-core and 16,542 in the multicore test. The DDR5 system shows a small decrease in the single-core result (to 2.069), but that is within the margin of error. In multicore, the DDR5 platform managed to achieve a performance improvement of 20% with a score of 19,811. This benchmark was first reported by Tom’s Hardware.

A similar benchmark was recently dug up by VideoCardz, this time with a technical sample of the mid-range Core i5-13600K. This time, the system still proved to be faster when paired with DDR5 RAM, but the performance boost was limited to just 11%. Even then, these improvements, as well as future-proofing your computer by using a DDR5 motherboard, may be enough to make many customers consider trying DDR5.

Intel introduced support for DDR5 memory with its current-generation Alder Lake platform, but adoption has been slow so far. DDR5 RAM is still too expensive, although the cost has slowly improved. As the technology becomes more widespread, prices should continue to normalize.

AMD’s next-gen Ryzen 7000 processors offer no DDR4 support at all, meaning Team Red enthusiasts will have to splurge on some of the best DDR5 RAM instead of sticking to DDR4. Both Intel Alder Lake and Intel Raptor Lake let you choose between DDR4 and DDR5, but it’s clear that using DDR5 can be a good way to get the most out of your new CPU.

Intel Raptor Lake is reportedly launching soon, with a rumored release date in October, alongside a slew of other next-gen releases from AMD and Nvidia.
