DDR4 vs. DDR5 RAM: What's the difference?

Source: Rich Edmonds / Windows Cardinal

PCs and their components are continuously evolving to deliver improve performance. Synchronous Dynamic Random-Admission Memory (SDRAM) — the stuff that allows for fast merely temporary storage in your PC — is no dissimilar, and over the years Double Data Rate (DDR) SDRAM has moved through generations. Up until recently, the most current common form of SDRAM was DDR4, which came later DDR3 and so on.

While Samsung is evidently already working on DDR6 SDRAM, the DDR5 generation has simply just come into focus with the release of twelfth Gen Intel Cadre "Alder Lake" desktop processors. These CPUs are so far the but mainstream chips compatible with DDR5 retention, though that's expected to change in the near future.

Permit's accept a wait at how DDR5 RAM compares to the older (but nevertheless relevant) DDR4 RAM, also as where information technology's compatible and whether it'due south worth the upgrade.

Major differences betwixt DDR4 and DDR5 RAM

SDRAM speed is generally measured in data charge per unit and clock charge per unit, and there are a few cardinal terms here to help make sense of the numbers. RAM information rate is measured in Megatransfers per second (MT/due south), peculiarly in official documents or when new products are revealed by major manufacturers. This measurement is not seen nearly as often for commercial listings, and if you've shopped for RAM earlier you lot're no dubiousness accustomed to something like "DDR4-3200MHz" being the standard naming convention.

Where does the "3200MHz" number come up from in this case? The MHz measurement has sort of informally become the get-to for the data rate besides, which is why nosotros generally encounter advertised numbers between 1,600MHz (MT/due south) and 3,200MHz (MT/s) for DDR4 RAM. DDR4 clock rates generally range from 800MHz to ane,600MHz, and you can run into where the "double data rate" in DDR comes from. Because the bus is transferring on either end of clock wheel (the upward and the down), it'due south effectively doubling the MT/s rate. Overclocking can push these numbers higher, and something similar the excellent Corsair Vengeance LPX sells at a three,600MHz (MT/s) speed.

DDR5 improves on DDR4 with both data and clock rates. DDR5 data rates generally operate in a range from 4,800MHz (MT/s) to 8,400MHz (MT/southward), with the latter number already rising as the engineering matures. For DDR5, clock rates also pick up where DDR4 leaves off, with a range of ane,600MHz to 4,800MHz.

Capacity, channels, and efficiency

Each stick of RAM (also chosen a DIMM) consists of a bunch of separate integrated circuit modules (or dies) depending on the RAM's capacity. Whereas DDR4 had a maximum die density of 16Gb, DDR5 quadruples that number to 64Gb. This translates to DDR5 RAM sticks with much more than overall capacity than DDR4. As our need for more memory increases, sticks of RAM with more 64GB capacity volition scale with DDR5.

While the overall data width for DDR4 and DDR5 remains the same, DDR5 aqueduct architecture has inverse. Each DIMM now has two channels instead of just i, improving efficiency by allowing the CPU to simultaneously access the same stick of RAM more once. DDR5 also doubles up on burst chop and outburst length compared to DDR4. Combined with the dual-channel nature of each DDR5 DIMM, this farther improves efficiency.

DDR4 RAM power direction is handled by the motherboard. This changes with DDR5, where at that place's a ability direction integrated circuit (PMIC) built right onto the stick of RAM. This helps ensure that power isn't beingness wasted on DIMMs that don't demand as much juice. And finally, DDR5 runs at a lower voltage than DDR4. It'south non a huge change, simply the drop from ane.2V to 1.1V will exist much more than axiomatic in smaller devices.

DDR5 real-world performance

DDR5 RAM offers some enticing improvements on newspaper, but how does this translate to real-earth functioning? In our Corsair Dominator Platinum RGB DDR5 and XPG Lancer DDR5 reviews, RAM-master Rich Edmonds tested raw performance across a bunch of benchmarks.

Facing these two DDR5 kits up against One thousand.SKILL Trident Z Neo DDR4-3600 RAM delivered some unsurprising results. Functioning was nearly on par save for a couple of tests. Transfer rates are excellent, but the higher latency (C38 for Corsair and XPG DDR5 kits) means there'due south still not a huge difference betwixt DDR4 and DDR5. It's the very early days for DDR5 technology, and it however has a long mode to go before it reaches the same maturity that DDR4 is currently enjoying.

Compatibility, availability, and pricing

DDR5 RAM is currently compatible with Intel'south 12th Gen "Alder Lake" processors, including the Intel Core i5-12600K, Intel Cadre i7-12700K, the Intel Core i9-12900K, and their KF counterparts. These CPUs are actually also compatible with DDR4 RAM, though motherboards will but work with one type of RAM. You volition take to decide before investing in a new motherboard.

Yes, the CPU socket has changed, so all 12th Gen Intel fries need an updated board. Prices for motherboards with DDR4 and DDR5 support differ quite a flake, which is axiomatic in our roundup of the best motherboards for the Intel Core i5-12600K.

Due to stock shortages, buying DDR5 RAM right now is almost impossible. And even when it is bachelor, it's significantly more expensive than DDR4 RAM. Our collection of the best RAM for 12th Gen Intel CPUs, which includes both DDR4 and DDR5 options, over again demonstrates some of the cost disparity.

Investing in DDR5 RAM correct now makes sense if you take a larger budget and tin actually find stock. Many people don't mind being an early adopter, and DDR5 has the potential to truly accident DDR4 away. If y'all're on a tighter budget merely still have a twelfth Gen Intel setup, it'due south clear that loftier-end DDR4 can keep up with electric current DDR5 performance. Our list of the best DDR4 RAM can assist you get what you lot need if yous cull not to adopt DDR5 in its current state.
