G.Skill introduces the first DDR5 kits with a CAS latency of less than 30 milliseconds.
G.Skill are excited to announce extremely low-latency DDR5 memory kit at DDR5-5600 CL28-34-34-89. It’s the first time to bring DDR5 XMP specification under CL30.
G.SKILL International Enterprise Co., Ltd., the world’s leading manufacturer of extreme performance memory and gaming peripherals, is excited to announce an extremely low-latency DDR5 memory kit specification at DDR5-5600 CL28 in 64GB (32GBx2) and 32GB (16GBx2) kit capacities, under the Trident Z5 RGB, Trident Z5, and Ripjaws S5 series and designed for the latest 12th Gen Intel® Core™ desktop processors and Intel® Z690 chipset motherboards.
Breaking the Sub-30 Latency Barrier on DDR5
With a focus on breaking the limits of low latency with DDR5 memory, G.SKILL is releasing an extremely low-latency sub-30 timing memory specification at DDR5-5600 CL28-34-34-89. Setting a new bar for low-latency timing performance, this memory specification with CL28 marks a new era of high-end DDR5 memory.
See the DDR5-5600 CL28 64GB (32GBx2) memory kit validated with the Intel® Core™ i7-12700K processor and ASUS ROG Maximus Z690 Hero motherboard in the screenshot below:
Availability & Specifications
The DDR5-5600 CL28 memory specification in 64GB (32GBx2) and 32GB (16GBx2) kit capacities will be available under the Trident Z5 RGB, Trident Z5, and Ripjaws S5 series in late May 2022 via G.SKILL worldwide distribution partners. For detailed specifications, please refer to the table below:

Love how people are always cracking on DDR5. Yes, its expressive but if u do the math DDR5 @ 5600 c28 is 10ns so it's the same as DDR4 @ 3200 c16 just like DDR5 6400 c32 is 10ns. Just like I'm running 6000 c30 so same latency with almost twice the frequency of 3200 c16. Anyways that is my two cents for the day.

The real latency in ns remains more or less the same between DDR generations, it seems. So, sequential transfer would greatly benefit from the high frequency, but random access delay would remain the same. At least in theory. Maybe there are some other factors with how the CPU predicts stuff and in the logic within the RAM modules themselves. They could be getting better from generation to generation.
Frequency is so high with these that latency comes second.

This is why I bought 5800x3d. I'll wait for DDR5 to mature another year

the jedec standard is definitely looser this time around, "tight" jedec is usually 10-12.5ns, going back as far as ddr
with ddr5 the tightest jedec is ~14ns.
frankly, given the amount of cache cpus have these days, it just doesnt really matter all that much. but there is defintitely a trade off being made design wise.
