Crucial RAM 16GB DDR5 4800MHz CL40 Laptop Memory CT16G48C40S5

Product Information

DDR5 marks a radical change in voltage regulation, too. The motherboard is no longer responsible for voltage regulation because the memory modules have a power management IC (PMIC). (12V on server-grade DIMMs and 5V on mainstream DIMMs.) Memory experts and system architects know that the latency matters only at the system level since that is what users typically experience. That said, system latency is also measured in nanoseconds and is a combination of host memory controller features and behavior, number of module ranks, memory speed, and true memory latency. Kingston's Fury Beast kit eschews flashy RGB and huge heat sinks in favour of a design that's subtle and discrete. If your PC is sitting under a desk, out of sight and mind, do you really need a lot of bling? DDR4 memory modules sport a single 64-bit channel (72-bit if you take ECC into account). In contrast, DDR5 memory modules come equipped with two independent 32-bit channels (40-bit with ECC). JEDEC also doubled the burst length from eight bytes (BL8) to 16 bytes (BL16). The upgrades, as mentioned earlier, improve efficiency and reduce data access latency. On a dual-DIMM setup, this transformation essentially turns DDR5 into a 4 x 32-bit configuration rather than the conventional 2 x 64-bit configuration on DDR4. The MAG Z690 Tomahawk WiFi implements MSI's Memory Boost technology, consisting of optimized memory circuits to supply pure data signals. In addition, the DDR4 and DDR5 motherboards bring DDR4-5200 and DDR5-6400 support, respectively, which is more than sufficient for our needs. Test System and Methodology

The G.Skill Trident Z5 Neo is some of the fastest DDR5 RAM you can get for an AMD system, featuring up to 6,000MT/s for high data access, write, and copy speeds whether for everyday use, content creation, or gaming.

What is the difference between Crucial DDR5 and DDR4?

AMD's Zen 4-based AM5 motherboards only support DDR5, while Intel's platforms do still offer DDR4 versions of their motherboards. Will DDR5 work on a DDR4 motherboard?

DDR5 modules have on-board PMIC and this regulates the power needed by components of the memory module such as DRAM, register and SPD hub). For server-class modules the PMIC users 12V and for PC-Class modules, it uses 5V. This means improved power distribution over the DDR4, better signal integrity and less noise. 5. On-Die ECC Support

It's the kind of kit that will have a long life, too. In a few years from now, 64GB will still be more than useful, especially if you're talking about a high-end gaming PC. Patriot Memory's Viper line of components have always offered great performance, and the Xtreme 5 RGB DDR5 RAM kits just solidifies this reputation thanks to absolutely daredevil-levels of speed. Remember that DDR5 is also present in SODIMM formats (for laptops) and as LPDDR5 for smartphones and other ultra thin designs.

The higher bandwidth of DDR5 is beneficial in other areas though, particularly in creative-type applications. DDR5 uses less power, 32GB is generally the baseline, and a DDR5 system is better for future-proofing. As time goes on, we can expect faster and lower latency kits. What platforms support DDR5 RAM? Even in its early days before independent software vendors or developers began optimizing for DDR5, we saw impressive results from DDR5 as reported by other publications too like Eurogamer, Tech Notice and Gamers Nexus 4: The UL Procyon benchmark, which runs a consistent, repeatable workload on a licensed install of Adobe Premiere Pro, shows that more bandwidth can help matters, with DDR5-4800 taking the win there. The results of this test still indicate some gains for reduced latency when moving from CAS 22 to CAS 14 at DDR4-3200, however.

Long answer: The problem with DDR4 and how DDR5 solves it can be explained with the help of these two tables. With a DDR4-3200 memory product, users can get up to 4.2 GB/s per core on an 8-core CPU. If they simply switched to a 16-core CPU while keeping the memory constant, their bandwidth per CPU core drops to 2.1 GB/s per core. This is a huge problem for data-heavy users and a wasted opportunity because they cannot realize the full potential of their new 16-core CPU.

With 2x the burst length, 2x the banks, 2x the bank groups, two independent 32-bit channels for non-ECC modules and the same bank refreshes, DDR5 greatly improves channel efficiency over DDR4. Moreover, DDR5’s launch speeds of 4800MT/s is 50% faster than the maximum DDR4 speeds of 3200MT/s. Both the improved channel efficiency and fasterspeeds of DDR5 helps break through DDR4’s bandwidth limitations for data-heavy applications and workflows — not just during testing, but in real-world conditions. What that tells us: The answer to the question "Which is better, DDR5 or DDR4?" really comes down to which tests you include (or don't include). But whatever your selector set is, the results remain close, at least with today's modules. Gaming with only 8GB of RAM in your system can be a dicey proposition. Yes, there are many games — including modern titles — that run perfectly fine with 8GB of memory. But if you want to play something demanding like The Division 2, which requires 11.3GB of RAM, 8GB simply won’t cut it. You’re better off streaming games from services like GeForce Now or Xbox Game Pass on PC if you only have 8GB of RAM. How much RAM most people need: 16GB

Should you upgrade to DDR5 RAM?

In terms of performance, the G.Skill Trident Z5 Neo unfortunately tops out at 6,000MT/s, but that's about as fast as you're going to get with an AMD EXPO module right now. On the plus side, the Trident Z5 Neo gets an average data speed of 87,196 MB/s and an average latency of just 51.5 nanoseconds when running at full throttle. This puts it just ahead of the PNY XLR8 Gaming Mako DDR5 by a smidge as far as performance-per-dollar goes (they're essentially even, honestly), so on top of being a fantastic performer for AMD users, you're also getting probably the best value you're going to find anywhere on DDR5 RAM. There’s a good reason computers are designed with both temporary and permanent storage, and it’s actually pretty simple: RAM is much faster than hard drives or their speedier solid-state drive cousins. The second tab in the chart above aggregates selected benchmarks that represent real-world applications, such as the App Startup subtest from PCMark 10, the Premiere Pro result from UL Procyon, all the apps from our timed workloads chart, and F1 2021. The combined figures are an average of those results. Thanks to its huge lead in 7-Zip file compression, the DDR5-4800 wins over DDR4-4000 by 1.5% overall. We also experimented with removing the timed benchmarks from this data set (not charted here), and in that scenario, the DDR4-4000 kit would have led by 1.3% without that additional data. He does have some examples of +20%-ish more performance for DDR5 6000 (at 1080p), in a few games, but there are other games with regression too (where DDR4 wins), which this article does not show... and that's important.
