DDR4 or DDR5?
“More RAM equals better performance.” Well, not exactly. While it’s a common belief, the type of RAM you choose can be just as important as the amount. Enter DDR4 and DDR5.

By Dylan Cooper
Let’s kick things off with a quote from the legendary Steve Jobs: “Innovation distinguishes between a leader and a follower.” When it comes to RAM, innovation is the name of the game. DDR5 is the new kid on the block, but does that make DDR4 yesterday’s news? Not so fast.
DDR4 has been the go-to memory standard for years, and it’s still widely used in most PCs today. But DDR5 promises faster speeds, better efficiency, and more bandwidth. So, should you jump on the DDR5 train, or is DDR4 still good enough for your rig? Let’s break it down.
Speed: The Numbers Game
DDR5 RAM is faster—like, a lot faster. We’re talking about a base speed of 4800 MHz, compared to DDR4’s 2133 MHz. That’s more than double the speed right out of the gate. And if you’re a gamer or someone who works with heavy applications, that speed boost can make a difference. But here’s the thing: not all software can take full advantage of that extra speed just yet.
DDR4, on the other hand, has been around long enough that it’s well-optimized for most current applications. Sure, it’s slower on paper, but unless you’re doing some serious multitasking or running memory-intensive programs, you might not notice a huge difference in real-world performance. So, while DDR5 wins in the speed department, DDR4 is still no slouch.
Capacity: More Is More?
DDR5 also has the upper hand when it comes to capacity. It supports up to 128GB per module, compared to DDR4’s 32GB. That’s a massive leap, but let’s be real—how many of us actually need 128GB of RAM? Unless you’re running a server or doing some hardcore video editing, 32GB is more than enough for most users.
That said, if you’re building a future-proof PC or you’re a content creator who needs all the RAM you can get, DDR5’s higher capacity could be a game-changer. But for the average user, DDR4’s capacity is still more than sufficient.
Efficiency: Power Play
One of the most significant improvements with DDR5 is its power efficiency. DDR5 operates at a lower voltage (1.1V) compared to DDR4 (1.2V). That might not seem like a big deal, but when you’re running a high-performance rig, every bit of power savings counts. Plus, DDR5’s improved power management means less heat, which is always a win for your PC’s longevity.
But again, DDR4 isn’t exactly a power hog. It’s been optimized over the years to be pretty efficient, and unless you’re running a massive setup, the power savings from DDR5 might not be a dealbreaker.
Price: The Elephant in the Room
Here’s where things get tricky. DDR5 is expensive—like, really expensive. As with any new technology, early adopters pay a premium. DDR4, on the other hand, is much more affordable, and since it’s been around for a while, you can find some great deals on high-quality modules.
If you’re building a budget PC or upgrading an older system, DDR4 is the clear winner in terms of price-to-performance ratio. But if you’ve got the cash to spare and want the latest and greatest, DDR5 is the way to go. Just be prepared to drop some serious coin.
Compatibility: Can Your PC Handle It?
Before you rush out to buy DDR5, there’s one crucial thing to consider: compatibility. Not all motherboards support DDR5, and if you’re upgrading an older system, you’ll likely need to stick with DDR4. Even if you’re building a new PC, you’ll need to make sure your motherboard is DDR5-compatible, which could limit your options.
DDR4, on the other hand, is compatible with a wide range of motherboards, making it a more versatile choice for most users. So, if you’re not ready to upgrade your entire system, DDR4 might be the better option for now.
Final Thoughts: Future-Proof or Budget-Friendly?
So, what’s the verdict? If you’re building a high-end, future-proof PC and you’ve got the budget to spare, DDR5 is the way to go. Its faster speeds, higher capacity, and improved efficiency make it the clear winner in terms of raw performance.
But if you’re on a budget or upgrading an older system, DDR4 is still a fantastic option. It’s more affordable, widely compatible, and more than capable of handling most tasks you throw at it.
In the end, it’s all about what you need and what you can afford. As with most things in tech, there’s no one-size-fits-all answer. But hey, that’s what makes building a PC so fun, right?
Remember when the first DDR RAM was released in 2000? It was revolutionary at the time, but now it’s a relic. The same will eventually happen with DDR4 and DDR5. The question is, how long are you willing to wait?
