DDR3 RAM vs DDR4 RAM
Here are the differences between DDR3 RAM and DDR4 RAM
In early 2016 RAM Manufacturers rolling out the latest memory chips in the form of DDR4. After using the same DDR3 standard for 9 years. But what benefits does DDR4 have over DDR3 in real-world applications and are they worth the increased cost?
Right now, there are three main types of RAM you can buy for a consumer-grade custom PC that is DDR3, DDR3L, and DDR4. The main improvements that DDR4 makes over its predecessor, DDR3, are a greater range of available clock speeds and timings, lower power consumption, and reduced latency. With DDR3, the options for your clock speed are primarily geared to one of four different choices: 1333Mhz, 1600Mhz, 1866Mhz, and 2133Mhz, with 2133Mhz being the maximum limit. 800Mhz and 1066Mhz configurations do technically still exist, but for the most part, these have been phased out of production.
DDR4, on the other hand, doesn’t seem to have any kind of ceiling on its clock speed so far, at least not one manufacturer have been able to reach. Every time it looks like it’s gotten as fast as it can go, someone else one-ups the rest of the competition and sets the new standard in extreme performance.
Power consumption for most DDR3 layouts will hover anywhere between 1.5 volts in default setups and up to 1.975 volts in overclocked machines, DDR4 RAM runs more efficiently at just 1.2v, a setting which can be reduced to a bottom of 1.05v depending on the stick’s manufacturer and the amount of RAM. The DDR3L standard does make some respectable headway in this department at 1.35v (the “L” stands for “Low-voltage”), but DDR4’s overall efficiency takes it a step further.
The last Difference that DDR4 makes over DDR3 is the maximum limit of memory it can store on a single motherboard. In the best possible scenario, the theoretical maximum limit of a DDR3 configuration is 128GB, while DDR4 is said to be able to max out at four times that amount, at 512GB. However, no systems have yet been shown to run either setup successfully in real-world testing.
So, Do You Need to Upgrade?
For the time being: not really. Buy If the main concern when building your next PC is making it as future-proof as possible, then go ahead and upgrade your PC Now.
