Crucial RAM 16GB Kit (2x8GB) DDR5 4800MHz CL40 Desktop Memory CT2K8G48C40U5

Product Information

For a little while at least, DDR5 is best left to early adopters who are prepared for any unexpected behaviors and see it as the price you pay for playing with the latest tech. Kingston FURY™ Beast DDR5memory brings the latest cutting-edge technology for next-gen gaming platforms. Taking speed, capacity and reliability even further, DDR5 arrives with an arsenal of enhanced features, like on-die ECC (ODECC) for improved stability at extreme speeds, dual 32-bit subchannels for increased efficiency and an on-module power management integrated circuit (PMIC) to provide juice where it’s needed most.

For more information and an overview of the differences, see our side-by-side assessment of DDR5 vs. DDR4. Is DDR5 better than DDR4 in data centers? Since the JEDEC DDR4-3200 standard is a BIOS option for the DDR4-supporting Z690 Extreme WiFi 6E, we selected it to form our performance baseline in the tests that follow. Apart from that, a custom-configured DDR4-3200 14-16-16-30 setting fills the gap between it and Mushkin’s DDR4-3600 CAS 16 XMP setting. Bandwidth and Latency TestsIt should also be noted that for the vast majority of games you can still easily get away with 16GB of RAM. Consider the current transition from PCIe 3.0 to PCIe 4.0. A lot of early PCIe 4.0 components require massive heatsinks and fans on the motherboards to keep things cool. DDR5 isn't likely to have the same issues, of course, but it goes to show that new technology transitions usually have a few issues at the start.

As we just saw, DDR5 offers a 3% performance boost overall, but here we can see that gains were as large as 20% in games such as Far Cry 6 and Bright Memory. Other games to show strong gains include Watch Dogs Legion, Assassin's Creed Valhalla, The Riftbreaker, and Fortnite, to name a few. Improved reliability: ODECC (on-die error correction code) detects all single- and double-bit error codes and resolves single-bit error codes before sending them to the host CPU/GPU. ODECC is an evolution included in the DDR5 specification that is designed to improve customer quality and enable future scaling.As the next evolution in DRAM (dynamic random-access memory), DDR5 enhances data processing applications that require substantial amounts of memory bandwidth, such as machine learning, artificial intelligence and big data analytics. DDR5 offers faster speeds, immediately delivering an 85% or higher increase in performance over DDR4. With a data rate (speed) range of 4800 to 8800MT/s, DDR5 delivers higher-performance memory and is geared to increase reliability, availability and serviceability (RAS).

Testing PUGB shows a small improvement to the 1% lows with DDR5, about 5 - 7% so nothing to write home about. Meanwhile, the average frame rate remained much the same, so either memory technology will allow you to squeeze the most out of an Alder Lake CPU in this game. Call of Duty Vanguard is another game where we find a negligible difference between the two memory types, even at 1080p. So it would seem this game isn't limited by memory bandwidth. Performance in Hitman 3 gains next to nothing when using DDR5, we see only a very minor increase at 1080p, with basically nothing at 1440p and 4K. Starting with Assassin's Creed Valhalla, we see a 13% to 15% performance improvement with newer DDR5 memory, taking the average frame rate from 121 fps at 1080p, to 137 fps. But more impressive than that was the 17% performance boost seen at 1440p when looking at the 1% lows with a 12% boost to the average frame rate. Counter Strike Global Offensive is a heavily CPU limited game, and here we see feeding the processor more bandwidth doesn't help improve performance at 1080p and 1440p, though we're only talking about a minor single-digit difference. But it appears as though lower latency memory is more important for this title.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. Fortnite also saw some benefit to using DDR5 memory, though for the most part the margins were less impressive. We did see a 12% boost to the 1% lows at 1080p, with a 6% improvement for the average frame rate and this was reduced to 5% at 1440p and then nothing at 4K. DDR5 offers benefits in many applications and is best suited for maximizing DDR5 server and workstation performance for AI, deep learning, high-performance computing (HPC), cloud computing, virtualized supercomputing, and in-memory database applications that demand the highest-speed real-time memory available. Superior speed advancements with double the banks from 16 to 32 and double the burst length from 8 to 16 take DDR5 memory, your gaming experience and your overall system applications to the next level of performance. Micron builds DDR5 server memory with power management integrated circuits (PMICs) on the module, meaning that customers are not paying for power management of the entire system. This design can initially mean a lower overall cost to power DDR5 servers compared to DDR4 servers when some system slots are left open. Micron server memory is high quality and typically less expensive than OEM server memory.

So why do this at all? It’s mostly being done because you can’t really quadruple the density of the chip without additional safety layers. Today, you’ll mostly only find ECC used in servers and workstations, because it’s done for mission critical reasons. The on-die ECC in DDR5 is just something had to be done to make the high speed and high density a possibility.

A game that doesn't benefit from the use of DDR5 memory is Battlefield 2042. Although this data is based on our easier to execute bot match, the 128 player modes don't see any improvement with the higher bandwidth DDR5 memory either. So this one is a bust for the ultra expensive DDR5 memory. We really have no answer to this right now. We can say that during previous memory transitions, the price premium was rarely worth it to those looking for practical impacts. That was typically due to the newer RAM typically starting very conservatively with speed and timings, with the older RAM benefiting from years of being pushed as fast as it could go. Based on those figures, DDR5 does very little to aid the Core i9-12900K across a wide range of today's games. These workloads also highlight the types of simulations, predictions and models of complex systems with large datasets that are often grouped with AI and other data analytics to support complex workflow analysis for both business and science. Their use helps reduce development time and costs in a broad range of applications. What are the energy-saving benefits of DDR5? For testing Microsoft Flight Simulator I'm using the latest DirectX 12 version and here we're only seeing mild gains in the range of low single-digit percentages, so nothing to get excited about.
