Based on those figures, DDR5 does very little to aid the Core i9-12900K across a wide range of today's games.
Micron DDR5 server memory delivers higher bandwidths along with improved reliability, availability and scaling than DDR4. It is 100% component- and module-tested to mission-critical server standards and optimized for the next-generation Intel® and AMD® DDR5 server and workstation platforms. As one of three major memory manufacturers, Micron tests and validates our DDR5 server memory to work with all major DDR5 server platforms.
Features
No, DDR5 server memory and DDR4 motherboards are incompatible. DDR5 will only fit in DDR5 server motherboards for all CPUs (central processing units) released into the market after October 2022. DDR5 is designed for data-intensive workloads like generative AI, machine learning, deep learning and other workloads running complex algorithms. How is DDR5 frequency categorized, in megahertz or megatransfers per second? 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. In contrast, the 7-Zip Beta compression/decompression benchmark shows tremendous gains in file-compression performance with the DDR5 kit. (See the 7-Zip results on their own tab.) So, in addition to the built-in 7-Zip benchmark, we added an actual 7.6GB file-compression time (a second 7-Zip result) to our timed benchmarks. 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?
Micron DDR5 server DRAM nearly doubles the performance of DDR4. Unlike DDR4, DDR5 is optimized to increase server and workstation performance by 85% or more. First introduced in 2014, DDR4 can no longer keep up with the demands of the data center. With more instances of actively running virtual machines on a single platform, DDR5 technology relieves the bandwidth-per-core memory crunch and increases the performance and responsiveness of virtualized applications. 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).
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. Here we see that the higher bandwidth DDR5 memory has boosted performance at 1080p by 15% and the same is also seen at 1440p when looking at the 1% lows. Even at 4K we're seeing a small 6% boost to 1% lows with the newer memory. 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.
Also, chances are 12th-gen Core series owners won't feel the need to upgrade until 14th-gen hits at the absolute earliest, and at that point you'd need a new motherboard anyway. 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. As for the other tests: Nothing meaningful in Cinebench R23, while DDR5 wins at the HandBrake bench. But most interesting of these results is 7-Zip, with that huge file compressing more than 20% faster on DDR5 than even the DDR4-4000 result. And, of course, it wipes the floor with DDR4-3200. Further fun with the data includes the Corona benchmark executing its highest rays-per-second with DDR4-4000. Power Consumption Testing and Performance Summary 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.
Awards and Reviews
They all told us DDR5 availability would be poor, and pricing would be extreme, and they were right...
As with any new technology, you can expect DDR5 to cost more than today’s comparable DDR4 modules. RAM maker Samsung has said to expect DDR5 to cost at least 30 percent more at introduction. That’s just for the chips themselves, too.
The Overclockers Difference
The data does move around a bit. For example, War Thunder is now showing the best results for DDR5, along with Doom Eternal. But overall we're looking at very similar performance trends. It also depends on how you see your investment in RAM too. Paying a premium for DDR5 in 2021 or early 2022 means you can use that RAM when building a new system in 2026 (where you’d have to toss the DDR4). But typically it’s better just to upgrade to a new memory standard a few years after it drops, when the RAM will be larger, faster and cheaper. Will next-gen CPUs be faster with DDR4 or DDR5?
