With the advent of the new generation of RAM, the company is returning to market in full force after the HyperX HP. The HyperX designation has been changed to Fury, and the new memory now consists of two models of the PC series – Beast and Renegade for nronch users. The Impact range is coming to the market for laptops and PCs

After seven years since the introduction of the DDR4 memory, the manufacturers of the motherboards received the first specifications and prototypes of the new DDR5 memory, which will be the standard for the coming years. At the end of 2021, the first pieces of hardware that were compatible with the new standard appeared on the shelves of dealers. Not only memory modules but also processors and PCI buses have changed. To take advantage of the full potential of the new architecture, many changes have taken place on the level of the base plate firmware.

Does it make sense to invest in new architecture and new memories? Many customers ask for a similar question. The main attraction for investing in DDR5 memory is clearly high speed and higher capacity. With the passage of DDR4, a non – paradoxical paradox arose in the water of the generation – the new generation was slower than DDR3. Thanks to an efficient production process, relatively high speeds have been achieved in water models, which are far from meeting their limits. According to JEDEC standards, DDR4 memories achieved transfer rates of 3,200 MT / s (megatransfers per second). The first real tests show that the transmission speeds of the new generation are at the level of 4,800 MT / s, with the potential to reach the limit at today under certain conditions and 8,670 MT / s, with a throughput of 67.2 GB / s . We can therefore conclude that in this generation of ns if certainly more than just the expected double increase in power. The current offer will consist of modules with speeds of 4400, 4800, 5200, 5600, 6000 and 6400 MT / s, while the basic speed is considered to be 4800 MT / s with 16GB capacity.

o is MT / where did the MHz mark go? The stated memory speed in MHz is a bit more burdensome, as the buses use lower operating frequencies than usual, but they reach the output current. For simplicity, assume that the memory frequency is 1500 MHz, but in each pulse a double is transmitted. Therefore, the manufacturer will mark them as 3000MHz, but the more expensive designation is 3000 MT / s, as the real amount of megatransfers is actually performed.

The memories have the same shape of modules and the same number of pins as the old DDR4 memory, but the compatibility of the notch between the pins is gently centered (unlike DDR4). Therefore, it will not be possible to accidentally insert DDR5 memory into an incompatible port (eg DDR4 port).

On the other hand, a change that is not visible to the naked eye is the number of child blocks (memories) in memories, the number of which has doubled from 16 (DDR4) to 32 (DDR5). Of course, this increase also brings with it a more efficient dt bus, which can provide twice the dt on the same bus as the previous generation and at the same time reduces the number of R / W operations. A new instruction for DDR5 memory also helps to increase efficiency and performance, which allows you to delete (clean) only certain data blocks (banks) from the group of blocks. DDR4 only allows the deletion of all data blocks.

A novelty with which DDR5 comes is the integration of its own circuit for the first voltage (PMIC module), which was found on the motherboard in the past. He also takes care of the loading of other components on the memory module and uses modules in the PC for example. also direct 5 V voltage for some components to improve the overall integrity of the signal and the wording of digital art. It is a convenient age that allows manufacturers to more efficiently manage the memory modules and their components and adapt it to the current need. The automatic speed correction circuit (ECC) or the new SPD hub component, which integrates SPD (Serial Presence Detect) EEPROM with other elements, also contributes to increasing the stability at extreme speeds. Of course, energy consumption is also a important factor. The operating voltage dropped compared to DDR4 from 1.2V to 1.1V.

The memory capacity itself has also changed. So far, the maximum capacity of DDR4 memory according to the JEDEC standard was 32GB, with DDR5 we get to the limit of 128GB.

How much RAM do we actually need for gaming?

With the increasing quality and size of the games, the hardware is also demanding. o Once upon a time the standard is at a minimum today. A sharp leap in FPS does not always mean only the upgrade of the graphics card, possibly the processor, but also the choice of the first speed and RAM capacity. The current standard set of assemblies is considered to be in the range of 8 – 16 GB RAM. In the table we can see (measured with DDR4 memories) that we should not underestimate the memory capacity.

Kingston results:

Nzov games FPS pri 4GB FPS pri 8GB FPS pri 16GB FPS pri 32GB
World of Warcraft 42 73 91 103
Call of Duty Warzone 43 61 69 81
Apex Legends 58 108 135 143
Fortnite 64 85 108 115

If the fast DDR5 memory is actually in the games?

In situcia, however, he arrives at the first speed and memory generation. The values ​​shown in the table were measured with 32GB of DDR4 and DDR5 memory. Specifically a test robil techspot.

Nzov games FPS DDR5 6000MT/s FPS DDR4 3600MT/s
Assassin’s Creed Valhalla 137 121
Battlefield 2042 154 155
Call of Duty Vanguard 198 202
Counter-Strike: GO 292 310
Far Cry 6 160 141
Fortnite 190 179

And if with current prices?

With the advent of the new generation, new prices also came, and the price increase in DDR4 was known. The first 16GB DDR5 kits were around 300 euros, 32 GB around 500 euros. Compared to DDR4, in some places it was almost three times the price. Together with the expensive motherboards, the problem was not to exceed the imaginary limit of 1000 euros by buying only RAM, processor and motherboard.

Currently the prices are better, 16GB DDR5 5600MT / s kit is d kpi u for less than 145 euros. But it’s definitely worth 16 GB DDR4 3200MT / s memory, which is currently moving at the level of 69 euros . If the capacity of memory is important, it is worth investing in DDR4, where for the same price you get an average of twice the capacity and stability. If you choose the same capacity in conjunction with cheaper motherboards, you can save a sum, for example, in a better graphics card or a larger SSD.

So it’s up to each of us to set our priority – I want the most capacity for less money, but they will achieve a hair or similar performance, or invest in state-of-the-art technology that will be supported in the future.

The passage of the new generation is always accompanied by software limitations that prevent the demonstration of the full potential of new technologies. But it’s just a matter of time, not new controls, firmware updates and game engine optimizations that really show the power of DDR5 memory.
