The data transfer rates for DDR, DDR2, DDR3, DDR4 and DDR5 in dual or single channel mode!Here are the single channel values, with dual, i.e. two memory slots modules in the dual channel, double + - (1-5%) is achieved, these are the maximum values that can be achieved when filling the memory with a certain value, so commands such as ZeroMemory, FillMemory, .... with CopyMemory one achieves in the best case 1/2 as an example Dual-Channel DDR3 1600 >> ZeroMemory: ~ 26GB / s CopyMemory: ~ 13 GB / s these are the maximum values with one measurement how, for example, Memory_Speed_Test can be measured. DDR data transfer rates:DDR 266: 2.1 GB / s DDR 333: 2.6 GB / s DDR 400: 3.2 GB / s DDR2 data transfer rates:DDR2 533: 4.2 GB / s DDR2 667: 5.3 GB / s DDR2 800: 6.4 GB / s DDR3 data transfer rates:DDR3 1066: 8.5 GB / s DDR3 1333: 10.6 GB / s DDR3 1600: 12.8 GB / s DDR3 1866: 14.9 GB / s DDR4 data transfer rates:DDR4 2133: 17 GB / s DDR4 2400: 19.2 GB / s DDR4 2666: 21.3 GB / s DDR4 3200: 25.6 GB / s DDR5 data transfer rates: (from 2020)DDR5 4800: 38.4 GB / s DDR5 5200: 43.2 GB / s DDR5 6000 48,0 GB / s DDR5 6400: 51.2 GB / s DDR5 7000 56,0 GB / s These are the values for single channel in dual channel twice as an example: DDR5 6400: 51.2 GB/s x 2 = 102 GB/s. The prerequisite is that it supports by CPU and the mainboard! Info:
By and large, you can already achieve intoxicating speeds, in the main memory if you start from FULL-HD so ~ 8MB you can chase it through the memory> 1000 times per second, just to understand the amount of data emotionally , or to capture. You can see a significant increase when saving , it is a tenfold increase in speed, but within 20 years , the development is far from what most think a doubling and so, every year, otherwise we would be in this case > 3,000 terabytes per second and not even at 0.025 terabytes / sec. But in direct comparison with a VW diesel 5 liter in 1990, 6 liter in 2020 it is a quantum leap! The nice thing is that, for example, a quad core with 3 GHZ can do 10-100 Giga calculations per second, which allows these memories to be handled properly, thanks to SSE, MMX and co ;-), or even AVX eight 32-bit Single -precision floating-point numbers, or four 64-bit double-precision floating-point numbers. Lookup: DDR5 is going to be a pretty big increase in bandwidth over DDR4. For server applications, this is a big deal. For consumers? It's going to take a while, which is why we're not sure when we'll see it on the desktop. It is believed to be at the exact same time in 2022 with PCIe 5.0. Like DDR4 modules, the DDR5-RDIMMS has 288 pins on a slightly curved edge connector. However, the layout and design are slightly different compared to DDR4 to prevent installing DDR5 modules in DDR4 slots and vice versa. FAQ 74: Updated on: 28 August 2023 07:03 |
