Memory chips are no longer put to use to just store data, but more so to enhance the functioning and speed of a computer program. Such Graphics cards have revolutionized the gaming scenario.
DDR 5 vs DDR 3
The difference between DDR5 and DDR3 is that DDR 5 has a much higher bandwidth than DDR3. Specifically, DDR 5 has 32 GB/s bandwidth while DDR 3 has 17 GB/s bandwidth.
DDR5 is a cutting edge technology and very new in the market whereas DD3 have been around since 2007. There are huge differences between the two since DDR5 SDRAM compatible motherboards are yet to be released.
Another crucial difference is that DDR 5 has a prefetch of 16n while DDR 3 has 8n prefetch. Prefetch here refers to prefetch architecture and the more prefetch buffer the more efficiently the RAM performs.
|Parameter of Comparison||DDR 5||DDR 3|
|Full form||Double Data Rate 5 Synchronous Dynamic Random-Access Memory||Double Data Rate Type 3 Synchronous Dynamic Random-Access Memory|
|Bandwidth||51.2 GB/s||17 GB/s|
|Voltage||1.1 V||1.3/1.5 V|
What is DDR 5?
DDR5 not to be confused with GDDR5 is an abbreviation of Double Data Rate Type Five Synchronous Dynamic Random Access Memory or DDR5 SDRAM.
DDR5 was first developed by SK Hynix in 2018 and then updated to 6400 MT/s chip version in ferbruary, 2019. It was finally released on 14th July 2020 in the market.
DDR5 is designed to use less power than its predecessors and run on 1.1 voltages. While this is cutting edge, there is still time before it is used generally for commercial purposes.
With such advanced technology one can only expect the prices to be sky high and incorporating them in server level initially is only feasible.
DDR5 uses DFE (Decision Feedback Equalization) which enables input/output speed adaptability for a higher bandwidth of 51.2 GB/s that this memory chip was primarily focused on.
As compared to its predecessors, DDR5 among many advanced features boasts a prefetch of 6/18n along with the power saving characteristics.
This prefetch buffer of 16n gives the fast edge to DDR5 since it capacitates the chip to read 16 units of data per second which is the most number of unit/s to be incorporated in a memory chip till date.
What is DDR 3?
DDR3 is a double data type Synchronous Dynamic Random Access Memory that is found in most client level laptops and Personal Computers. This memory chip was first released in 2007 and since then has been extensively used for several client and server level technologies.
It boasts double the transfer data rate than its immediate predecessor and is armed with a higher bandwidth and peak speed values.
DDR3 also boasts a higher prefetch buffer value than its predecessors with 8n prefetch. Which means it can read 8 units of data per second and is 8 times faster than DDR2.
DDR3 has a bandwidth of 17 GB/s and runs on a voltage power of 1.3V to 1.5V. DDR3 was curated to transfer data twice as fast as DDR2 and transfers data at a rate of 800–2133 MT/s. However, it has been replaced by DDR4 in the year 2014.
Although, in 2007 these bandwidths were only required by high-end graphics that required data transfer between framebuffers but soon they were being used for all computers and PCs for enhanced performance.
DDR3 was also made very different from its predecessor DDR2 in shape so as to prevent accidental interchanges. DDR3 boasts a 240 pin DIMMS and had square notches whereas DDR2 had round notches that made them visibly different.
Main Differences Between DDR 5 and DDR 3
- The main difference between DDR5 and DDR3 is that DDR 5 has higher bandwidth than DDR3 for DDR 5 has 32 GB/s bandwidth while DDR 3 has 17 GB/s bandwidth.
- DDR5 has a prefetch of 16n while DDR3 has 8n prefetch which means DDR5 can transfer data at twice the rate of DDR3.
- DDR5 is designed to use less power than its predecessors and run on 1.1 voltages while DDR3 runs on a voltage power of 1.3V to 1.5V.
- DDR5 was first developed by SK Hynix in 2018 and then updated to 6400 MT/s chip version in February, 2019 whereas DDR3 was first released in 2007.
- DDR5 is cutting edge and there is still time before it is used generally for commercial purposes while DDR3 has been extensively used for several client and server level technologies.
