Does latency matter with DDR5?

Short answer: DDR5's latency is virtually the same as DDR4. The key takeaway is that users can adopt DDR5 memory technology without worrying about latency performance.

Which DDR5 RAM has the lowest latency?

Skill has announced the release of the fastest DDR5 memory kit to date (opens in new tab). At DDR5-6800 with a CAS latency of 32, the kit offers a tantalizing combination of high speed and low latency.

Does RAM latency really matter?

Latency deals with how fast the RAM module can access its own hardware, and in this specific case, the lower the numbers, the better. Lower latency means faster data access, thus faster data transfer to the CPU, and faster operation of your computer overall.

Does DDR5 affect gaming performance?

One of the best DDR5 kits will still offer a great gaming experience, but the delicate balance of speed and latency puts high-end DDR5 in a precarious position. On one hand, faster DDR5 can offer practical differences in some games, but on the other, even faster kits can result in lower performance.

What is a good DDR5 RAM timing?

We consider 5200MHz to be a good sweet spot DDR5 kit for a mainstream 12th Gen system. At 4800MHz, it doesn't add enough over a 3200MHz or 3600MHz DDR4 kit. And, as is the case with all DDR5 right now, the Corsair kit is too expensive to make any sort of value case.

RANT: THE CAS LATENCY TIMING DOESN'T MATTER AS MUCH AS YOU THINK IT DOES

Why are DDR5 timings so slow?

DDR5 inherently has more bandwidth by the way it was designed. As for why the timings are so much looser on DDR5, that's the way it goes for every new DDR release.

What is the timing of DDR5 6000?

Corsair Vengeance RGB brings a competitive DDR5 kit, with an XMP 6000 MT/s profile and modest timings of 36-36-36-76.

What is the CAS latency of DDR5 RAM?

To throw a brief bit of maths at things, the real-world CAS latency is measured as (CAS Latency x 2,000)/Memory Speed, which in the case of the DDR5-5600 CL28 kit comes in at 10ns. For reference, that's the same as DDR4-3200 with a CAS latency of 16.

What is the sweet spot for DDR5 RAM?

AMD's Ryzen 7000 Zen 4 CPUs appear to have DDR5-6000 as their sweet spot, allowing for a 1:1 IFC ratio. A 1:1 ratio indicates that the memory operates at the same frequency as the memory controller on the CPU, which should provide the best-case situation.

Is it worth getting DDR5 over DDR4?

DDR5 is better, but at what cost? DDR5's performance reaches more than double the fastest DDR4 modules. Coupled with Intel 12th-gen and upcoming 13th-gen processors or the new AMD Ryzen 7000-series processors, PCs are faster and more powerful than ever before.

Is CL18 better than CL16?

In terms of CAS latency and speed, CL16 is a little better than CL18. But from the prices, the CL16 is more expensive than the CL18. So, if your budget is not too much, you can choose CL18 for your computer.

Which RAM latency is better?

When the memory frequency is the same, the lower the CL, the shorter the latency time will be, and the less time the computer has to wait to read the memory data, which means the better the performance.

Is 22 latency bad?

Latency is measured in milliseconds, and indicates the quality of your connection within your network. Anything at 100ms or less is considered acceptable for gaming. However, 20-40ms is optimal.

What is the quickest DDR5 RAM?

Corsair Vengeance RGB DDR5 32GB 5,600MHz C36

This DDR5 RAM has more on offer than just great looks. It's also fast, stable and overclocking ready. A great choice for modern gaming PC builds. Corsair's Vengeance RGB has long been a favourite with PC gamers thanks to its clean aesthetic and great lighting.

At what speed is DDR5 faster than DDR4?

You can never have enough memory bandwidth, and DDR5 helps feed that insatiable need for speed. While DDR4 DIMMs top out at 3.2 gigatransfers per second (GT/s) at a clock rate of 1.6 gigahertz (GHz), initial DDR5 DIMMs deliver a 50% bandwidth increase to 4.8 GT/s.

What is the fastest DDR5 possible?

Viper Venom DDR5 series is the fastest DRAM by Patriot Memory. It comes with a starting frequency of 4800MHz. Patriot Viper Venom RGB DDR5 32GB (2 x 16GB) 6000MHz UDIMM Desktop Gaming Memory KIT -… The groundbreaking technology lets it be twice as fast and have double the bandwidth than DDR4.

Is 16GB DDR5 good for gaming?

16GB is the recommended amount of RAM for playing most games and will provide a noticeable increase in performance from 8GB. You will also be able to run applications in the background without affecting gameplay.

What CPU do you need for DDR5 RAM?

DDR4 vs DDR5 RAM: Compatibility

Intel's 12th- and 13th-generation, plus AMD Ryzen 7000 are the only desktop CPUs that currently support DDR5, and Ryzen 7000 is the only one that absolutely requires it.

Does DDR5 RAM run hot?

DDR5 modules will run hot without active cooling when your testing. 45c idle temps with VDD, VDDQ voltages under 1.43V is indeed a bit warm. You need more air flow across modules, or your chassis ambient air temps are vary high.

Is RAM speed or latency more important?

True latency is a much better indicator of performance, as it takes the number of clock cycles and the length of each clock cycle into account.

Is 40 latency good?

Generally, an acceptable latency (or ping) is anywhere around 40 – 60 milliseconds (ms) or lower, while a speed of over 100ms will usually mean a noticeable lag in gaming.

What is the CAS latency for 3600MHz?

The 3600MHz unit, for instance, has a CAS latency of 18 whereas the 3200MHz unit is a C16 kit.

What is the timing of DDR5 4800?

They both operate at DDR5-4800 with 40-40-40-77 timings and only require 1.1V to hit the advertised data speeds. TeamGroup's DDR5-4800 memory modules adhere to JEDEC's specifications for DDR5 and pack a built-in power management IC (PMIC) and voltage regulator module (VRM).

Is CAS latency 36 good?

The higher CAS numbers keep the real time latency similar to the real time latency for DDR3/4, but the RAM is much faster in all other ways. They will not go down to anything close to 10-20 over time. 36 is pretty good already.

Is 1000 ms latency bad?

If your ping is around 1000ms (1 sec) or higher, it is definitely going to result in players suddenly appearing and disappearing all over the screen, continuous buffering of videos and overall gameplay running incredibly slow.
