It’s finally Time To Do PC gaming On DDR5 ?
G.Skill, a memory manufacturer, just announced the first DDR5 RAM that has a sub-30 CAS latency. The new DDR5 memory will be available in 32GB (2x 16GB) and 64GB (2x 32GB) sizes. The in-game latency of these kits is comparable to decent CL16 DDR4 kits, and that shows a benefit in-game. We’ve seen a recent increase in Extreme DDR4 DRAM frequencies, but we’ll need those latencies to decrease as well.
G.Skill‘s announcement is good news for DDR5 because now there are benefits to using DDR5 besides just synthetic benchmarks and specific high-memory usage situations. Hopefully, other producers will soon follow suit. The real-world CAS latency is calculated by multiplying the CAS Latency by 2,000 and then dividing it by the Memory Speed. For example, in the case of the DDR5-5600 CL28 kit, it would be 10ns. That is comparable to DDR4-3200 with a CAS latency of 16 for reference.
With more overall frequencies, the gaming experience improves. While this might only translate into a few frames per second, it helps make DDR5 a more appealing platform for gamers.
The Alder Lake processors from Intel already support the latest memory standard (as well as DDR4), but Zen 4 from AMD is expected to only operate on DDR5. More backing should, in theory, increase demand, which will eventually lead to a decrease in pricing. Eventually. G.Skill has not released pricing information yet for these memory kits, but they will be more expensive than DDR4 because DDR5 is twice as expensive.
