Which is faster, 512MB RAM DDRII 533 or DDR400, and what is the price difference?

The DDRII 533 is fast, but ** cheaper than the DDR 400!

What is the price difference? It depends on the brand.

The modern price difference is 80 yuan.

The price difference of APACER memory is 55 yuan.

Kingmax (Shengchuang) price difference is 65 yuan.

You can check the other brands again!

Of course, the DDRII 533 is faster!!

You can go on your own.

Look at their performance parameters and prices above!!

Of course, DDRII 533 is fast, but it needs your motherboard to support it, ** almost, under normal circumstances, DDRII 533 is generally cheaper by twenty or thirty yuan.

Only to say that the DDRII 533 is better.

It depends on what platform, some motherboards can only support up to 400, and you can only reach the speed of 400 when you buy 533.

If the motherboard is good, you will be able to pick 533 very quickly.

The DDRII 533 is a little faster and around 400 more expensive than the DDR20.

It's almost the same, I use 400, although my board supports 533, but I think it's not much worse, if you really want to change DDR2, it's better to change the board directly and go to 800! 400 for 533 is better than not changing!

DDR5 performance is nearly 60% higher than DDR4.

The DDR5 4800 is up to 50% better than DDR4 and nearly doubles the memory bandwidth, and is available in 8GB, 16GB, and 32GB specifications. The introduction of voltage regulation and power management integrated circuits, which are no longer placed on the motherboard, improves the signal quality, and its operating voltage is only and can be adjusted more flexibly, and also brings some easter eggs, such as "overclocking".

Key features:

The main feature of DDR5 SDRAM is chip capacity, not just higher performance and lower power consumption. DDR5 is expected to bring an IO speed of 4266 to 6400 mt s, with the supply voltage dropping to V, with a permissible fluctuation range of 3% (i.e. Each module uses two independent 32 40-bit channels (not using or using ECC).

In addition, DDR5 will have improved command bus efficiency, as the channel will have its own 7-bit address (add) command (cmd) bus, better refresh schemes, and increased memory groups for extra performance.

The performance gap between DDR4 and DDR5 is about 20%.

When DDR4 was first launched, the mainstream memory frequency was generally only 2133 and 2400MHz, and the memory frequency was further increased to 2666MHz or above in the later stage.

At present, the frequency of flagship DDR4 memory can reach 4266MHz or higher. The starting frequency of DDR5 memory released in the early stage of the market is 4800MHz, which has basically reached the limit of DDR4 memory, DDR5 memory in addition to the 4800MHz frequency of Rock God Letter, and at the same time, there are higher 5200MHz and 6400MHz frequencies released, and it may be higher in the future.

The minimum frequency of DDR4 memory modules is 2133MHz, while the minimum frequency of DDR5 is 4800MHz, which greatly improves the frequency, and the work efficiency of DDR5 memory is much better than DDR4 memory in terms of productivity, and it is about 3% ahead of DDR4 in terms of games. In the game performance test, it was concluded that DDR5 is about 1-5 frames higher than DDR4 in the game.

Key features of DDR5:

1. Equivalent frequency increase:

The increase in the equivalent frequency that everyone can feel the most is directly increased from "2133MHz" to "4800MHz", and with the deepening of DDR5 memory parameters, 6400MHz may become the mainstream level. The increase in frequency has improved the theoretical score of DDR5 memory, and the performance results have been greatly improved in terms of read test, write test, replication and latency.

2. DRAM capacity increase:

In the DDR4 specification of JEDEC, the maximum capacity of a single memory die is only 16GB, and in the DDR5 era, the capacity of a single die has reached a height of 64GB.

3. The working voltage is lower

The working voltage of the coarse wheel storage in DDR5 is as low as that of DDR4, which is the lowest working voltage for blind ears than DDR4, and the working voltage is reduced by about 20%.
