![]() Not all workflows are sensitive to memory bandwidth, and that’s as true for DDR5 as it was for DDR4 and DDR3. It’s fair to note that not all applications benefit equally from DDR5. For memory-intensive workflows that run up against the limits of DDR4, that’s a game-changer. Through fundamental changes to the DRAM architecture, it offers more than twice the effective bandwidth of DDR4. Following this analogy, upgrading from DDR4 to DDR5 is like replacing old, narrow pipes with much wider ones. Think about a water pipe: you can pump water faster in order to increase flow, but you can boost the efficiency even more by increasing the diameter of the pipe. Gobs of bandwidth for power usersĬompared to DDR4, DDR5 doesn’t merely bump up memory bandwidth compared to DDR4. DDR5 lets you scale your memory bandwidth even as you bolster your CPU core count. Pair a sixteen-core CPU with a DDR5-4800 memory kit, and you’ll maintain the same 4Gbps bandwidth per CPU core. But if you upgrade that CPU to a 16-core model, you end up cutting your per-core bandwidth in half. That works out to roughly 4Gbps of bandwidth per CPU core. For example, let’s say that you have an eight-core CPU and a fairly standard dual-channel DDR4-3200 memory kit. The more cores that a CPU has, the less memory DDR4 memory bandwidth is available per core. Here’s where DDR4 starts to show its age. Intel and AMD have responded to this demand by adding more CPU cores. DDR4 RAM became available back in 2014, and the computing needs of many users have increased dramatically since then. Right off the bat, it’s important to note that DDR4 wasn’t designed with today’s multicore processors in mind. How is it different from the DDR4 we’re so familiar with? What do you need to know as you’re shopping for a memory kit? What advantages does it bring to the table? Here, we’ll dig into the essential differences between DDR5 vs DDR4 so that you know exactly what you’re getting with next-gen memory.īetter scaling for today’s multi-threaded CPUs That means that it’s a good time to take a closer look at DDR5. ![]() Odds are, if you’re building a PC or buying a laptop right now, you’re going to be getting DDR5 memory - or at least considering it as an option. And our X670 and B650 motherboards? The entire series supports DDR5. We now offer mini PC options with DDR5 RAM. Our Z790 motherboards primarily, but not exclusively, support DDR5. Look at our 2023 lineup of ROG laptops - they feature DDR5 RAM from top to bottom. Not that long ago, DDR5 was a future promise.
