ADATA and XPG DDR5 Memory Test Performance, the High Performance and Valuable DDR5 Memory

What are the different features between DDR5 and DDR4

Story Highlights
  • DDR5 memory that comes with 12th generation Core processors.
  • It's still hard to get, but I was given the opportunity to borrow products from the ADATA and XPG brands, so I checked their performance this time.

ADATA and XPG DDR5 Memory Test Performance. DDR5 SDRAM has become a hot topic. It is the successor to DDR4 SDRAM, which has long been in the mainstream, and is only supported as the main memory of 12th generation Core processors, so its performance and functionality is eye catching.

From ADATA, which has a proven track record in memory related products, DDR5 memory products have emerged from the original “XPG” and “ADATA” gaming brands. This time, while explaining the new specs and functionality, I would like to examine the behavior and performance of using this.

What are the different features of DDR5 and DDR4 SDRAM?

DDR5 SDRAM is a high-speed memory standard that replaces DDR4 SDRAM. The origin of DDR is “Dual Data Speed”. It comes from synchronizing with the memory clock and transferring data twice per hour. The basic mechanics are unchanged in DDR5, but various improvements have been made to achieve higher speeds.

ADATA AND XPG DDR5 MEMORY TEST PERFORMANCE: DDR5 DIMMS HAVE 288 PINS. SAME AS DDR4, BUT NOT ELECTRICALLY COMPATIBLE. THE POSITION OF THE NOTCH ON THE TERMINAL SECTION IS ALSO DIFFERENT, AND IT IS NOT POSSIBLE TO INSERT A DDR5 DIMM INTO A DDR4 DIMM SOCKET AND VICE VERSA.

Now, the key points of DDR5 are detailed as follows.

  • The high-speed memory standard that replaces DDR4
  • Not physically and electrically compatible with DDR4
  • Data rate 6400MT/s with JEDEC standard specifications
  • Improved data transfer efficiency and increased effective band
  • PMIC implementation for power management
  • Adopt I3C Interface
  • Improvements to the Intel XMP 3.0

In addition to the above differences, there is “On-Die ECC” which is taken as a new function of DDR5. To ensure the reliability associated with the increased transfer speed in the DRAM chip, an error correction function is provided at the transfer stage in the die. This should be a function that improves reliability, but was added as one of the solutions to problems associated with significant acceleration, and it is not a function that should be collected. This is a different feature of the module-level ECC features found for servers.

In addition, 64-bit channels can be treated as 32-bit independent channels in the past, but there are some misunderstandings. Although it is one of the specifications that contribute to effective bandwidth increases such as access efficiency in multicore environments, it does not mean that dual channel access (64bit x 2 = 128bit access) in the conventional sense can be done with a single module.

Greatly increased data rates and increased effective bandwidth

The biggest feature of DDR5 is the much faster data rates. The data rate on the JEDEC specification is 3200 MT/s, which is the highest in DDR4, while 6400 MT/s in DDR5, which is twice as fast.

In DDR4, high-speed memory with data rates exceeding the standard specifications set by JEDEC has emerged, but the same is true for DDR5. High-speed modules with data rates of 8400MT/s and 12600MT/s have been announced.

The data transfer efficiency has also been greatly improved. For example, even though the data rate is the same, 3200MT/s, the rated data bandwidth for DDR5 is significantly faster than DDR4.

Burst length is particularly relevant to this increase in efficiency. Think of it like the number of freight vehicles on a freight train. In other words, the amount of data that can be transferred by exchanging one command is doubled. It’s an impactful change to grow from 8 to 16 since the days of SDRAM (non-DDR).

Additionally, there are specifications to improve high-speed transfers and transfer efficiency, such as prefetching (look-ahead) and doubling bank groups, changing the bank refresh method, and introducing a mechanism that allows a 64-bit channel to be accessed as two 32-bit subchannels. Various have been introduced.

Newly implemented PMIC, speed up sideband communication

DDR5’s operating voltage is 1.1V, which is slightly lower than DDR4. In DDR5, this voltage is generated by a voltage regulator chip called PMIC (Power Management IC) on the module. While minimizing the installation of chip capacitors to stabilize the voltage, a stable and high-speed current can be supplied, and power efficiency can be expected to increase. However, it is not always the case that the product is actually more power efficient than DDR4 at the module level, as it is offset by high speed operation.

While minimizing the installation of chip capacitors to stabilize the voltage, a stable and high-speed current can be supplied, and power efficiency can be expected to increase.

The fact that the sideband communication interface has been changed from I2C (1MHz) to I3C (12.5MHz) and the speed has been increased is likely to have an impact in the future. This interface is used to connect an addressable RGB controller and a temperature sensor. In other words, since there is room to make this kind of function more multifunctional, it is possible that it will be used as an element to increase the value added of memory and motherboards in the future.

Intel XMP for high-speed memory semi-automatic setup has also been expanded to DDR5, and the version is 3.0. Up to three vendor profiles, previously two, can now be saved, and new user profiles can also be saved. The PMIC implementation allows for more flexible voltage control, and since it can also be specified in the profile, more OC effects can be expected.

After all, the height of the effective bandwidth of DDR5 memory is clear

The performance test environment is as follows. The XPG Lancer DDR5 was also tested with rating settings (DDR5-5200, CL40) when the XMP profile was not loaded. Since the environment is completely different, this is for reference only, but the DDR4-3200 score as measured by the AMD Ryzen system is also posted.

Intel vs AMD Environment

In the AIDA64 Extreme bandwidth test, the DDR5-5200 setting marked excellent scores of 71.6GB/s for reading and 74.6GB/s for writing. The theoretical bandwidth of DDR5-5200 dual channel is 83.2GB / s, and in terms of efficiency with respect to the theoretical value, read reaches about 86% and write reaches about 90%. This efficiency is also common to DDR5-4800.

Compared to the AMD DDR4-3200 environment run for reference, the bandwidth difference is obvious. Comparing the effective efficiency of the memory copy, it can be seen that the effective efficiency of DDR5-5200 is 84%, while that of DDR4-3200 is 80%, which means the transfer efficiency is also good.

The difference between DDR5-5200 and DDR5-4800 is also clear. FINAL FANTASY XIV: Even in the final Akatsuki benchmark, there is a slight difference of about 10.5%, but it is also reflected in the actual application performance.

DDR5 memory is expected to spread smoothly in the future. First of all, I want the shortage situation to be resolved

The appeal of DDR5 is its high performance. Not only theoretical value but also good execution performance. Memory performance is not directly reflected in the performance of the entire system, but the faster the CPU, the greater the impact. This means a lot when using high-end CPU cores.

On the other hand, I’d like to point out that parts like DDR5’s “reliability” and “power saving” aren’t overemphasized. It can be said that the application of on-die ECC and 1.1V operating voltage is needed to solve the problems that arise in advancing high-speed and high-performance.

However, with the introduction of PMIC implementations as a way to increase speed while suppressing heat generation and power consumption, the room for customization has expanded rapidly. In the future, more value-added products that take advantage of the I3C and XMP 3.0 interfaces will appear. There is no doubt that DDR5 will make your home PC more enjoyable.

DDR5 continues to suffer from serious drawbacks. Unfortunately, the situation is the same for the ADATA and XPG products shown this time. I hope this situation will be rectified and will expand if given smoothly by developers.
