Ddr3 vs DDR4 vs ddr5 vs ddr6 (RAM buying guide) specs explained graphic ram types

RAM Buying guide for 2021 year, RAM specs Explained,  learn how to check the RAM slots, speed, Storage using windows task manger, Know the price and performance different among DDR3, DDr4, DDR5, DDR6, and DDR7 and so on.

Things to consider  before buying a ram for pc / laptop

Check maximum supported ram,

RAM support for 32 bit processor /os 64 bit

32 bit system only supports upto 4gb ram. Seriously it’s limited the performance. Now a days all are 64bit , if you install 32 bit on windows on 64bit processor.

Check Available RAM  Slot in windows 10

click on task manager or CTRL+SHIFT +ESC and Click Performance

2.slots dual ram slots gives additional performance when compared to single ram.
However buying 2x 8gb rams individually , better for buying 16gb ram,
Buying 4gb rams now maybe outdated except in 2nd sale.
3.maximum supported bandwidth
(I bought 2444mhz RAm  it’s old i5 2nd gen processor supports 1600mhz)

Ddr3 vs ddr4 vs ddr5 vs ddr6 RAM difference

 

RAM Type Speed / clock frequency Voltage Speed Price
DDR2 533 mhz –  667mhz 2.5v 7.5GB/s
DDR3 1066 to 18600 mhz 1.5 17GB/s
Ddr3l 1066 to 18600 mhz 1.3 17GB/s
DDR4 2133mhz to 3200mhz 1.2v 25.6GB/s
DDR5 (GPU) 3200MHZ to 1.1v 32GB/S
DDR 6 (GPU)_ 1v
DDR 7 (Graphic cards only)
Ddr5 vs ddr6

Graphic card RAM DDR 5 VS DDR6 for gaming rtx

RAM Type Speed / clock frequency Voltage Speed Price (based on size / storage )
GDDR5 (GPU) 1545MHz 1.5 V 8 Gbps $200
GDDR5X 1730 MHZ 1.5 V 10 to 12 Gbps $250
DDR 6 (GPU)_ 1730 MHz 1.3 V 14 Gbps to 16 Gbps $300
DDR 7 (Graphic cards only)
Each and every generation aims to
Higher speed & lower voltage. As of now 2020 intel supports only upto ddr4 for its processor. check Intel processor List. But graphic cards at ddr5&ddr6 (ddr4 out dated for gpus).  check my GPU Buying Guide.
ddr3 vs DDR4 vs ddr5 speed

RAM bandwidth speed?

Be sure to check out the maximum memory bandwidth supported processor. in every generation higher bandwidth version available with slightly higher price.
Ddr2 –  12GB/S
Ddr3 – 16GB/S
DDR4  – 25GB/S
DDr5 –  32GB/S
DDR6 –

Ram voltage /power consumption by Type

Ddr6  – 1V
DDR 5 – 1.1v
Ddr4 – 1.2 V
Ddr3l 1.3v
Ddr3 1.5
Ddr2 2.5v

ram specifications explained

Capacity storage (8GB) –  main factor for buying.
Stick Type (DDR4, DDR6 Etc)
Clock Frequency (2400MHz) / RAM speed

RAM Storage: The main factor when you out of memory or memory 100% then you need to Upgrade. when disk is 100% Then you need to Upgrade HDD to SSD.

These days at least 8GB RAM needed, gone 2GB ram, 4GB RAM days application like chrome designed to used more ram as Possible.

RAM Type DDR4 Vs DDR5 vs DDR 6 VS DDR 7 and 8 so in.

Higher the number the better Speed and higher price for newer models because of R&D Cost has to include for first few years.
Speed, Low Voltage.
RAM speed Or clock Frequency
You may find 2 variants in DDR3 RAM 1800MHZ and 1600MHZ even 1300MHZ.    Higger generation higher speed ex: DDR4 Starts from 2400MHZ speed.

DDR3 vs DDR4 physical difference

DDR3 vs DDR4 vs ddr5 dim size
Prefetch in DDR4 vs ddr3

DDR3 vs ddr3l Difference

L=lower voltage 1.5 vs 1.35

How to check supported ram by your /pc laptop Motherboard?

Just windows task manager,
Click performance & memory
You can see memory type & available slots.
Ddr3l with 1300mhz
also check the processor
Ex i5 2nd gen 5320M support ddr3l but not at maximum speed rate, if you install higher bandwidth ram it utilizes only supported bandwidth.
generally laptops do have 2 memory channels.
Desktops 2-4 based on motherboard.
Newer version of Rams tend to higher price.
(Because of R&D)
consider price to performance wait for few time to get cheaper price.
Ex: intel previous generation price drops as soon as next gen release.
sometimes lower generation processor with less computing power than present generation sold at high because of popularity on amazon ex: amd ryzen 2nd gen x series processor.

How memory bandwidth calculated?

MT/S Memory clock speed
& Memory width in bits.(32,64,128,256).

DDR3 vs DDR4 compatibility

you cannot use DDR4 RAM in DDR3 RAM slot you can check physical difference Between DDR3 and DDR4 from above image.

windows task manager memory explained

ShortCut: CTRL+SHIFT +ESC

 

You can check RAM Speed Supported By motherBoard:

RAM Usage * total Size of RAM

RAM Slots:  2 or more laptops only have upto 2 ram slots. Incase of PC (check motherboard buying guide)

Form Factor : SODIMM

windows task manager memory explained

 

Faqs on DDR RAM types (2-6)

Is 8GB of DDR4 actually better than 16GB of DDR3?

DDR3 RAM  max speed is 2400,  and DDR4 RAM speed starts from 2400MB/sec . so 16GB DDR3 90% better than 8GB DDR4

Is DDR4 better than DDR3 for gaming?

Yes! Because of More bandwidth Rate and Less Power consumption.

Is it worth upgrading from DDR3 to DDR4?

No, Its a Minor Affect Price High Price Performance ratio 100:1.

Is GDDR6 better than GDDR5?

GDDR6 is approximately 50% faster than GDDR5. That doesn’t mean that a graphics card using GDDR6 will be significantly faster; the GDDR6 variant of the 1650 is only around 6% faster than the original GDDR5 1650.

is graphic RAM Size or speed important for gaming?

RAM Size is the main factor that differential other factors in GPU. you can also Check 2nd factors as cuda cores and clock speed and bandwidth rate of GPU processor.
