Does faster RAM really make a difference in your frame rates?

Since the whole world moved over from the original DDR memory, timings have come to play second fiddle to bandwidth and capacity. More megahertz, more gigabytes, those are the numbers we have been sold on, but does any of it make much of a difference? Now that manufacturers are managing to take DDR4 above the 4GHz mark, it’s time we settled the argument.

Fortunately we don’t need to go out there and do the testing ourselves — the guys at TechSpot have already conducted some pretty thorough testing, and the results are illuminating to say the least.

For its benchmarking session, TechSpot took five different speed memory kits, beginning at 2,133MHz and finishing up at the 4,000MHz mark, testing them alongside a pair of GTX 980 Ti graphics cards and a Core i7-6700K processor — so the CPU and GPU certainly won’t be bottlenecking the memory.

The results performed as you would expect in synthetic benchmarks, with memory tests showing gains when you crank up the memory frequency to almost twice that of the entry-level kit. But what about when we move over to more real-world scenarios?

Photoshop, Excel, and Handbrake all showed big performance improvements from using the faster memory, in some cases by as much as 57 percent. That shows that even for people just looking to make their day-to-day work more efficient, faster memory could go a long way to making that a reality.

But it’s in gaming that we were most surprised by the results. While certainly processors and graphics card upgrades are almost always going to be the most effective way to improve your frame rates, games like ARMA III saw a 10 percent FPS improvement when opting for 4,000MHz memory over the 2,133MHz counterpart.

Fallout 4 was the most affected, however, with even a bump from 2,133MHz to 3,000MHz leading to an improvement of almost 20 percent.

The conclusion from the testing would suggest that if you already have a strong processor and graphics card, but are running slow, or suffer from low-quality memory, you might be handicapping your system more than you think.

You probably want to make sure you’re running a Skylake chip to take full advantage, and you can probably settle for 3,600MHz memory over 4,000MHz, as the gain from taking that further jump isn’t really worth the extra cost, but it’s good to see that there is another upgrade path for those looking to squeeze a few extra frames per second out of their system.

What’s the difference between DDR3 and DDR4 RAM?
ddr3 and ddr4 differences man s hand holding computer ram memory card

DDR3 RAM had a long run after its 2007 release, powering mainstream laptops and desktop computers for many years. However, in 2014, DDR4 RAM was released to the public and has since become the most common memory type in desktop PCs, laptops, and tablets. With major changes to its physical design, specifications, and features, motherboards with DDR4 slots cannot use DDR3 RAM, and DDR4 RAM can't be put into a DDR3 slot. Neither is compatible with the newer DDR5 memory.
DDR4 versus DDR3 RAM
DDR4 tends to run at 1.2 volts by default, whereas DDR3 runs at 1.5V. While it may not seem like much, that's a 20% improvement in efficiency between generations. For most home users, the difference in voltage ultimately results in lower power consumption and heat generation, which can be especially important in laptops where it can impact battery life.

DDR4 is not just more power efficient -- it's a lot faster, too. DDR3 specifications range between 800 to 2,133 MTps (millions of transfers per second). In comparison, DDR4 RAM ranges between 2,133 to 3,200 MTps, not to mention the faster kits available through XMP and overclocking.

The best laptops for programming
Surface Book 2 op-ed header

There's a lot to consider when shopping for the best laptop for programming. Taking out a bank loan for the device you need isn't ideal, but you certainly don't want to rely on a snail to get the job done, either.

A laptop with a four-core processor is best, given all the code-crunching and everything else running in the background. On the memory front, programmers should have at least 8GB of RAM, though 16GB or higher is ideal. The Dell XPS 15 is the best of the bunch because its ultra-thin and fast.

RAM has never been cheaper, but are the historic prices here to stay?
jedec ddr5 specifications 2018 memory ram

RAM prices are at historic lows. But it hasn’t always been that way.

If you upgraded your PC's memory in 2018, you might be kicking yourself right now. This writer certainly is. I upgraded from an old, faithful 16GB of 1,600MHz DDR3 to a 16GB kit of Corsair Vengeance RGB 3,000MHz DDR4. It cost me the equivalent of $200 at the time. That same kit today is just $75. What the hell happened?
