What is the difference between DDR4 and DDR5 RAM?

With the arrival of the 12th Generation Intel Core Alder Lake CPUs, consumers have been given access to the new format of DDR5 RAM memory, successor to the DDR4 RAM memory. There are already several DDR5 memory modules on the consumer market that we can buy, but… What is the difference between DDR4 and DDR5?

What is the DDR of a RAM memory?

They are the acronym for Double Data Rate, and it is what is called a generation of SDRAM memories that comply with a protocol of form, operation and voltages. Changes are introduced with each generation to make them more efficient in terms of latency, voltage consumption, overclocking options and maximum capacity per module and per channel.

In summary, what differentiates memories of different DRR generations are differences in their memory efficiency and power consumption.

Each generation of DDR memory also comes with a slight change in physical output and its connectors, and this difference is maintained in the transition from DDR4 to DDR5. If you have ever dealt with RAM memories from several years ago, you may have seen that some modules do not fit on some motherboards, and that is that each DRR generation standardizes where a small notch is inserted that prevents a memory from not being inserted into a motherboard base designed for a different generation of DDR RAM.

This is why there is the case of a card for motherboards with DDR5 that allows the introduction of DDR4 memory that was leaked by an ASUS developer, so that they can enter physically. But this is more of an internal concept, not a product for the end market.

DDR4 Memory Features

Front of DDR3, DRR4 memory introduced higher DIMM density, lower voltage requirements and higher data transfer speeds. KThe higher module density of the DDR4 standard allows DIMMs of up to 64 GB capacity, compared to DDR16's maximum of 3 GB per DIMM.

The standard divides the DRAM banks into two or four selectable bank groups, in which transfers to different groups of banks can be made more quickly.

Su lower voltage It allows you to reach more speed without requiring more energy or cooling. DDR4 switched to operating at a voltage of 1,2 V with a frequency between 800 and 1600 MHz compared to DDR3, which operated at 1,5 V to have frequencies between 400 and 1067 MHz.

DRR5 memory characteristics

In late 2021, DDR5 memory hit the consumer market thanks to the 12th generation Intel Core processors known as Alder Lake. Intel has been the first to bring DRR5 memory support to home consumers, as its Alder Lake processors contain the drivers so that they can run them physically. These drivers may be updated in the future to improve efficiency and compatibility.

DDR5 introduces a new feature called Decision Feedback Equalization, which enables I/O speed scaling for higher bandwidth and better performance. The DDR5 format supports more bandwidth than DDR4, with 4,8 gigabits per second possible. In the latency section, it will have approximately the same as DDR4 and DDR3. multiplied by eight the maximum capacity of DIMMs, which go from 64 GB to 512 GB; and its frequencies are higher than those of DDR4.

The memory voltage is further reduced to 1,1V, thus reducing power consumption. DDR5 modules can incorporate voltage regulators to achieve higher speeds in exchange for a higher cost in manufacturing, with which it is expected that they will only be used in the RAM destined for servers of services in the cloud and in the top-of-the-range modules. Lastly, DDR5 supports a speed of 51,2 GB/s per module and 2 memory channels per module.

What do I need to have DDR5 memory in my computer?

First of all is purchase DRR5 memory modules. There is already a long list of manufacturers that have released their first packages of DDR5 memory modules. But two of the biggest problems that DDR5 memory faces is its high price, derived from being a still modern technology with little demand and therefore little profit margin; and the difficulty of finding them, due to the current shortage of components and semiconductors.

Next, you'll need a compatible motherboard. At first these were mid-range or higher, since their implementation was still expensive, although in recent months low-end models have begun to appear. We already commented that due to the physical difference that exists between generations of DDR memory when introducing a notch, it is necessary that the motherboard is de facto made for DDR5 memory. This is important on Intel 12 processors, which support both DDR4 and

The last thing you're going to need is a compatible CPU, of which only Intel Core Alder Lake are currently available. Going forward it is expected that future generations of Intel will also accept DDR5 and eventually abandon the DDR4 format, mainly because the new CPUs are made for enthusiasts who want to upgrade their PC, or for completely new computers. In the case of AMD, they do not yet have DDR5 compatible CPUs on the market and therefore, there are also no DDR5 motherboards for AMD CPUs. But it is expected that with the new Zen 4 generation, DDR5 will be introduced to the AMD ecosystem.

Difference between DDR4 and DDR5 explained in a simple way

DDR5 versus DDR4 memory differs in that it allows modules have higher capacity and higher speed using less power consumption. To have DDR5 in our computer, apart from the memory modules, we must have a compatible motherboard and CPU.

When is DDR5 released?

DDR5 is now available on the market, in base seats compatible with 12th generation Intel Core or higher, and in AMD abse boards compatible with Ryzen 7000 or higher.

How much does DDR5 RAM consume?

DRR5 RAM consumes 1,1 volts, compared to 1,2 volts for DDR4 RAM. This means they have slightly lower consumption.

How to know if my RAM is DDR5?

You can tell if your RAM is DDR5 by going to Windows Task Manager, and going to the Performance section. There they will give you information about your RAM memory, among which is the DDR5 format of your RAM memory.

What if I put DDR5 on DDR4?

First of all, you can't put a DDR5 RAM module into a DDR4 RAM connector, because the connector prevents that. If you were to modify the connector to insert DDR5 into a DDR4 connector, you would have performance problems and could damage the RAM module and motherboard.

What is the latest DDR?

The latest DDR format is DDR5, which appeared at the end of 2020. The DDR6 format is being developed, which are expected in 2026.

How do I know if my PC accepts DDR5?

The only CPUs compatible with DDr5 are 12th generation Intel CPUs or higher, with B660, H610 and Z690 motherboards. In the case of AMD, it is Ryzen 7000 CPUs with AM5 motherboards.

How do I know if my laptop supports DDR5?

To find out if your laptop supports DDR5, you can check the type of RAM it is using in the Task Manager.

What is better DDR4 or GDDR6?

They are not comparable, since DDR4 is the volatile memory format for RAM memory, and GDDR6 is the memory format for graphics cards.

What is the fastest RAM?

Currently, the fastest RAM is DDR5.

How many gigs of RAM are recommended?

About 8 GB of RAM is recommended for all users, and 16 GB of RAM for gamers.

What happens if I put a lot of RAM on my PC?

If you expand your PC's RAM, the faster it can work and the faster programs will run. But the RAM memory frequency will have to be compatible with that of the CPU, since they have to be synchronized.

What is better DDR4 or DDR5?

DDR5 RAM improves DDR5 RAM in all aspects. Its biggest difference is the price, because it is a newer technology and is more difficult to find.

What processor supports DDR5?

Currently the processors that support DDR5 are the 12th, 13th and 14th generation Intel, and the AMD Ryzen 7000 CPUs.
