What is Sdram used for?

Summary of the Article

SDRAM is faster and more efficient than other forms of RAM. DDR versions of SDRAM have extremely fast data rates as they can use both edges of the clock. SDRAM has an access time of 16 to 12 nanoseconds.

DDR memory is better than SDRAM as it can transfer data at roughly twice the speed. PC133 SDRAM runs at 133 MHz, while 133 MHz DDR effectively runs at 133 MHz x 2 = 266 MHz.

SDRAM is no longer used in consumer devices.

DDR SDRAM transfers data on both the rising edge and falling edge of a clock cycle.

The disadvantage of SDRAM is that it gets synchronized with the system clock and cannot be used with older motherboards. It also works in a single data rate per clock cycle.

8GB of SDRAM is good for playing most games, but some might not play at the highest quality.

RAM is usually better than SSD for increasing the type and number of programs you can run simultaneously, but it depends on your current RAM capacity.

SDRAM is used in laptops when upgrading the capacity, and notebook SDRAM modules are usually 144-pin SO-DIMMs. DDR SDRAM sends and receives data twice as often as common SDRAM.

DDR4 SDRAM is the baseline standard in PC gaming, but DDR3 can still be used if you’re not building a high-end rig.

The amount of RAM you need depends on your usage. Generally, 8GB is recommended for casual usage, 16GB for office programs, and at least 32GB for gamers and multimedia creators.

An 8GB RAM and 256GB SSD combo is enough for a computer. SSD is non-volatile and permanently saves data, while RAM needs to be refreshed continuously.
