The data transfer rates for DDR, DDR2, DDR3 and DDR4 in dual or single channel mode!Here are the single channel values, with dual, i.e. two memory slot modules in the dual channel, double + - (1-5%), these are the maximum values that can be achieved when filling the memory with a certain value, So commands like ZeroMemory, FillMemory, .... with CopyMemory you can reach 1/2 in the best case as an example Dual-Channel DDR3 1600 >> ZeroMemory: ~ 26GB / s CopyMemory: ~ 13 GB / s these are the maximum values with one measurement such as Memory_Speed_Test that 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 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 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 6400: 51.2 GB / s Info:
On the whole you can reach intoxicating speeds, in RAM if you start with FULL-HD now ~ 8MB you can chase it> 1000 times per second through memory to understand just the amount of data emotionally , or to record. You can see a significant increase in saving , it is a tenfold increase in speed, but within 20 years , the development is nowhere near what most people think is doubling and so, every year, otherwise we would be in this case > 3,000 tera bytes per second and not exactly at 0.025 tera bytes / sec. But in direct comparison with a VW diesel 1990 5 liters, 2020 6 liters, it is a quantum leap! The nice thing is that a quad core with 3 GHZ can do 10-100 giga calculations per second, which makes it possible to treat these memories 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.
