DDR5 RAM Review, Release date 2021: DDR5 Vs DDR4 Comparison

June 5, 2021

Through the hardware globe, we have moved all around generations of GPUs and processors, but we are even rocking the similar DDR4 RAM which might be in the ideal gaming PCs for many years. Luckily, DDR5 modules can relate to the corner, as production is in full swing and producers like Corsair are teasing the next standard. Even though memory is not the most fascinating topic, compared to selecting the ideal graphics card, DDR5 RAM even brings the big potential for huge efficiency enhancements for future PC builds with the frequency nearly double its predecessor.

Besides, it is not all about enhanced bandwidth, as DDR5 might even tackle capacities until 128GB per DIMM slot, which seems like an abundance of Chrome tabs for us. Sure, you might want to combine a lot of modules with the ideal gaming motherboard during their implementation later that year, but those speeds and even capacities are certain to recognize DDR5 on the top of ideal gaming RAM instruction.

Overview DDR5 RAM

Release date

The customer release of DDR5 might coincide with Intel’s Alder Lake’s launch later that year. Next, Corsair can affirm again that the release is imminent with the recent post, claiming DDR5 memory is coming early.

Unluckily, AMD’s Zen 3 processors are following from the red group, and those might not assist DDR5. On the other hand, AMD clients might keep waiting for Zen 4 that is needed to land on shelves next year.


DDR5 carries other incremental enhancements through the traditional standard. Unlike the highest 32GB of capacity for DDR4 sticks, DDR5 can raise that to the potential 128GB per module. Next, it is based on the program and game devs to code their software to make most of all that additional capacity as well.

The base frequency of DDR5 can begin around 4800MHz, boosting up to a highest of 8,400MHz – greater than the most extreme overclocks with DDR4. You might hope the standard clock speeds to lie anywhere in between, but frequencies can be tied for the processor.


Early adoption costs with modern memory standards are high like we realized with DDR4’s proposed release. DDR4 is by no means outdated yet so that you may need to hold out with the following gen of memory till prices can settle.


It might not seem like the Alder Lake rigs might be able to execute the recent standard as motherboard producers want to make either DDR5 or DDR4 motherboards for LGA 1700 sockets. Then, AMD rigs will not realize DDR5 till 2022 with Zen 4 as the innovation of Zen 3+ refresh is not needed to assist the incoming memory standard.

DDR5 and DDR4 comparison

Memory bandwidth

The key distinctions from DDR4 to DDR5 memory are the bandwidth. Memory bandwidth is identified by how quickly the data might be conveyed from CPU to memory to SSD/HDD. The pins’ number with the DDR5 memory can be a similar amount to the DDR4. However, the frequency can boost DDR5 and thus the memory bandwidth.

Next, around the normal spec sheet, DDR4 memory brings the highest bandwidth assistance of 3.2 gigabits per second per pin. The DDR5, in the other words, brings the highest bandwidth of 6.4 gigabits per second per pin.

On top of it, DDR5 comes with a dual-frequency than DDR4. The normal DDR4 RAM brings a frequency from 1600 to 3200 MHz. By overclocking the DDR4 RAM, it might get up to 5000MHz. Whereas DDR5, out of the box, supports a frequency range until 6400MHz. And if you can overclock the DDR5 RAM, the frequency might move up until 8400MHz. However, the primary item is that the DDR5 might get a greater frequency than DDR4.

Power consumption

The following distinction from DDR4 to DDR5 is power control. In the other words, the solution DDR4 memory power control is finished via the motherboard slot. On the DDR5 module, there is a single chip named PMIC (Power management integrated circuit) for every chip with one stick to deal with the power control.

So if the DIMM module requests a lot of power than various DIMM modules. Next, that specific DIMM module can get additional power instead of boosting the power to all various DIMM modules that do not need a lot. Finally, it shows DDR5 might be quite power-efficient than DDR4.

Channel texture

Another key distinction is the channel texture. At this moment, you might understand about double-channel memory and quad-channel memory for various slots with the motherboard. Besides, the method you obtain dual-channel and quad-channel configuration is putting the RAM sticks with double slots or four slots. As usual, the slots get similarly colored or labeled on, showing where you might place various RAM sticks.

With the quad-channel and dual-channel configurations, the CPU might use a various amount of data for every channel. Whereas if there is a single channel the CPU might particularly take a single amount of data at this moment.

Currently, every DDR4 stick comes with a single channel. It is derived from 72 bits, and 8 bits for error correction. By DDR5, every RAM sticks moving to get double channels. Each of these channels is around a 40-bit bus. It wants to get approximately 32 bits of data pins and 8 pins for error correction.

Thus, the data pins’ numbers are similar to either DDR5 or DDR4. However, as for DDR5, you can get double channels rather than one. So every RAM stick might be much more productive.

Burst length

At this moment, this one is quite complicated to clarify so we are going to attempt mostly to explain it. The method RAM can store data into it is the type of arrays. And the solution the arrays are based on might be like the columns and rows’ grid. For every grid box of the XY coordinate plane, lies one bit that might be 1 or 0.

While a specific bit of data wants to be extracted, the DDR5 and DDR4 RAM might particularly access stored data bit per row. Showing that if the RAM’s stick wants to take data from three various rows, it might not access three pieces of that data at the same time. It might move row by row and take every piece of data this way.

Let’s consider the data bits are on a similar row, in this situation, all RAM kinds might not even access private addresses at the same time, but what they might do is to scan various columns from the similar row back to back. So if there is a lot of data the RAM might scan that.

The highest number of data bits RAM might scan from the row is named burst length. What you might get away from that explanation is that burst length permits every RAM to get access to a lot of data in action.

Memory Capacity

The last huge distinction from DDR4 to DDR5 is the whole capacity of one RAM stick. In the other words, a DDR4 module boosts up to 16 gigabits of data for a memory chip. The memory chip might be put on a single side of the RAM stick or all sides.

RAM producers make various chips on the RAM. For instance, let’s consider a sum of 16 chips placed on one RAM stick. And every chip has 16 gigabits of data. Therefore, 16×16 = 256 gigabits or 32GB. The total capacity of the RAM stick is around 32GB.

On top of it, DDR5 comes with 64 gigabits of data per chip. So if you make a calculation by getting 64×16 = 1024 gigabits or 128GB of capacity for one RAM stick. However, it is based on the producers to make the highest chip’s density on the stick.

Wrapping It Up

Those are all key distinctions you might realize on DDR5 RAM. DDR5 is a big enhancement from DDR4. The DDR5 memory’s availability is needed too late 2021. Although if you purchase DDR5 RAM right after launch, you can not use it since it is not compatible with CPU or motherboard. As DDR5 brings other architectural transformations, the opportunities for BIOS enhancement are high so as to assist traditional gen hardware. Or if you want to plan to make a new PC with the next generation CPU can get the assistance of DDR5.
