DDR5 memory chaos 12 kinds of frequency and latency how big the difference

Although DDR5 is already available in large numbers, but this upgrade process is not destined to be smooth, in addition to the high price of the new product, there are also higher frequency DDR5 also has significantly higher latency, which will certainly have an impact on the performance of the problem. Our previous push mentioned the third-party media testing the performance of DDR5 4800/5200/6400, which is not enough, this time we introduce a larger test, more frequency and latency settings can explain more problems oh.

01

The DDR4 memory for this test was the Chips Ripjaws V DDR4 3600 16GB x 2 (timings 16-20-20-34 1T); the DDR5 memory was the Chips Trident Z5 RGB DDR5 memory with 16GB x 2 capacity, set to 3 timings at 4800MHz, and set to 10 frequencies at CL36 timings. The processor uses Core i9-12900K and the motherboard is ASUS Z690 Maximus Hero (DDR5) and ASUS Z690 STRIX-A Gaming D4 (DDR4).

02

With upwards of 4,000 data in the test, we’re sure to be overwhelmed, so here’s just a look at the relative performance of the combined different test items. In the application performance, it is a comprehensive data comparison based on Super π, wPrime, CINEBENCH, Redering, Machine Learning, 7-Zip, etc. models of pure computing power, design and development power, media processing power, and even AI power.

03

In the benchmark test, DDR5 performance is basically synchronized with the frequency, DDR5 5200 is 2.6% lower than DDR5 6000, DDR5 4800 is 3.8% lower, about every lower grade (400MHz), the performance will lose 1.5%. Pull down to 2400MHz then the benchmark performance loss of 30% on average, then, the game performance?

In the lower resolution game tests that test CPU performance, the frequency produces a larger gap than in the benchmark tests, with the DDR5-4800 and DDR5-6000 differing by 5.1% at 720p resolution. 720p/1080p resolution DDR5 2400 will even lose more than half of the game frame rate. The three typical timing states of DDR5 4800 can be seen in the highest data. The performance difference between CL30, CL36 and CL40 may not seem significant, but note that the performance at CL 30 is already close to DDR5 6000.

Look at these “head” data, we will find that the performance of DDR4 3600 really makes a difference, in the game test close to DDR5 6000, professional performance also exceeded DDR5 4800, really outstanding performance is very strong, plus now the price is not much higher than DDR4 3200, than DDR5 If you’re looking for a brand new machine, you can really consider choosing it for memory.
