On your quest for the best RAM for your PC, you might have heard the terms DDR2, DDR3, and DDR4. You might be wondering what is the difference between DDR3 And DDR4, apart from the number. Well under the hood these RAMs have quite a lot of difference that makes them better or worse. This article will help you to understand which type of RAM is best suited for your hardware snd which is best suited for the type of work you’ll do on your PC.
What Is RAM?
RAM (Random Acess Memory) is the component that helps the CPU to access the memory faster. It has the benefit of speed when compared to a hard drive and an SSD. The connection between a RAM and a CPU is called a speed bus because it helps the CPU to access the memory files faster when compared to the speed of a hard disk or even an SSD. DDR stands for Double Data Rate.
Major Difference Between DDR3 and DDR4 RAM
Now let get into some numbers and find ou the real difference between DDR3 and DDR4 memory.
1. Transfer Speed
Well from the name you can probably tell that DDR4 is the newer one and has better transfer rates. In a RAM, transfer rates are the main unit that makes a RAM fast or slow. They are measured as million transfers per second(MT/s) and Gigatransfers (billion) per second(GT/s).
A DDR4 RAM has a better transfer rate as compared to DDR3, for example, DDR4 has a transfer rate of 2133MT/s to 4266MT/s. On the other hand, a DDR3 can only go from 800MT/s to 2133MT/s. A DDR.
2. Clock Speed
The other difference between DDR3 and DDR4 is the clock speed. Clock Speed is measured in megahertz, this allows the RAM to read and write data faster. This in layman’s term means that your computer will run much faster on a DDR4 as compared to that of a DDR3. The final difference in hardware between a DDR4 and a DDR3 is the Column Access Strobe Latency which refers to the number of clock cycles that a RAM takes to deliver information when requested by the CPU. But sometimes a fast clock speed doesn’t mean that a DDR4 is faster.
3. Power Efficiency
A DDR3 ram, when compared to a DDR4 ram, consumes more power it isn’t a huge number. With a DDR4 this happens because of the slightly different architecture. DDR3 uses 1.5V and a DDR3L which is a newer model of a DDR3 that uses 1.35V.
When compared to a DDR4 it sits at a 1.2V it isn’t a noticeable difference but sometimes can cause your CPU to heat less because when a piece of hardware uses more power it will cause the CPU to heat up. This is not recommended in the long run.
4. DDR4 Costs More than a DDR3
The most crucial difference between DDR3 and DDR4 is the cost. Of course a DDR3 costs less than a DDR4 because it is an older version of the RAM. When DDR4 was first released the price gap was quite big. As of now a DDR3 and a DDR4 don’t have a lot of price difference, DDR3 costs around 2000RS. and DDR4 costs about 3000RS. This becomes a deciding force when it comes to deciding the amount of RAM a computer should have.
5. Hardware Compatibility
The other deciding factor that comes in is the motherboard and the CPU. If your motherboard is not compatible with a DDR4 then you won’t be able to use a DDR4 because the RAM slot will be very different and in that case, you will have to buy a new motherboard. The other thing that should be kept in mind is the CPU and which generation it belongs to. If it is a 4th or a 5th generation CPU then will not support a DDR4.
If you’re are buying all new hardware then it is recommended that you go for a DDR4 and it is also recommended for a lot of gaming setups. A CPU also has a limit on the amount of RAM that it can support most of the CPU’s can only support up to 32 GB so be careful about that as well if you’re going for a DDR4.
If you are going for a new build with a budget even as low a $450 you have some pretty good choices for DDR4 compatible hardware. Asus has a great line of motherboards starting from as low as 4ooo bucks. For the CPU you can go with an Intel i3 9th generation with a clock speed of 3.6 GHz and can overclock up to 4.2 GHz.
These are the main recommendation if you are going for a DDR4 RAM in a new build. If you want to upgrade your RAM you might want to go with a DDR3 because it is supported for older hardware but also works fine if you are using it for medium gaming and some office work.
In the end, the best option for a new PC build will be if you go with a DDR4. This will be very beneficial for your hardware as a DDR4 will make your PC work faster. A newer RAM stick will be hugely beneficial if you are performing intensive tasks on your PC like gaming, programming. Tasks like these always require the latest hardware because they get updated very quickly. I hope this article helped you get a better understanding of your hardware.
