DDR3 vs DDR4<\/strong>: If you are in search of a new system, then you might be researching a little bit on the hardware. So you must have come across the curves of DDR3 vs DDR4 RAM.<\/p>\n As hyped earlier, DDR4 RAM has the highest performance. But is it necessary to have a DDR4 RAM in your system?<\/p>\n Most of the time we come to decide the performance and the capability by seeing the number. Higher the number means more the performance as per most people. But is it justified all the time? Especially in this case?<\/p>\n Well, this is not a yes, no question. We have to analyze so many things to differentiate between DDR3 vs DDR4 RAM.<\/p>\n Without further delay, let’s dive into it.<\/p>\n Let\u2019s discuss some major differences DDR3 vs DDR4<\/p>\n The design may be the most important thing when we are going to release a successor of technology. Same thing in the RAM.<\/p>\n The DDR3 RAM used a 240-pin package. But the design has changed in the DDR4 RAM. DDR4 has uses a 288-pin package. This directly boosts in the bandwidth capacity and we will discuss it further in the article.<\/p>\n The pin-to-pin distance is also changed. In the DDR3 RAM, the distance is 1.00mm while in DDR4 RAM the distance is 0.85mm.<\/p>\n In DDR4 you can see the increase in height as well. Its height is 31.25mm as compared to DDR3 30.35mm.<\/p>\n Printed circuit boards are also thicker now. It becomes opens the scope for more signal layers.<\/ins><\/p>\n DDR3 RAMs apply a single voltage source across the whole module. This may affect stability but this thing is changed in DDR4. DDR4 RAMs work differently. With the help of voltage reference ICs, it enhances the lower voltage before each memory chip. This ensures that a consistent voltage flow and applied across each of them individually unlike the DDR3 the whole module at once. Thus it improves the stability of the modules of the DDR4 RAM.<\/p>\n If you are looking for the DDR3 vs DDR4 then you should take this point as number one priority.<\/p>\n The clock speed of DDR3 RAMs ranges from 800Mhz to 2133Mhz. The RAM manufacturers can\u2019t maintain the clock speed.<\/p>\n So we can see the remarkable improvement of DDR4. The minimum clock speed of DDR4 is 2133Mhz and no specific max value. The increase in clock speed directly increases in their bandwidth.<\/p>\n Also, read – Google\u2019s New Fuchsia OS<\/a><\/p>\n Manufacturers are trying to reduce the power consumption of the RAM. The result is, we get it in DDR4 RAM. The DDR4 RAM operates at a quite lower voltage of 1.2 volts as compared to 1.5 volts DDR3 RAM.<\/p>\n You may think that power consumption is not much in first sight. But the thing about a company or farm having 1000s of CPUs. When you add the power consumption units then this might a significant saving. It will also increase the battery life of laptops.<\/p>\n If you are comparing DDR3 vs DDR4 RAM, you will not neglect this point at all. DDR4 RAM is more stable than the DDR3 because it operates at a lower voltage and applies it consistently provide power to each individual memory chip.<\/p>\n <\/p>\n You can\u2019t notice the performance of DDR4 in a normal task like editing an MS Word document or listening to music. But you\u2019ll definitely appreciate the power when playing high-end games, editing video, using Photoshop, compiling software, etc.<\/ins><\/p>\n The increased clock speed and bandwidth leads to an increase in the latency as well. The DDR3-2133 has a latency of ~55 nanoseconds. The DDR4-2133 has a quite high latency of ~63 nanoseconds. The latency is not that high.<\/p>\nDifference between DDR3 and DDR4<\/span><\/h2>\n
