nak tahu beza antara graphic card DDR2,DDR3 dan DDR5..adakah key notch die beralainan seperti ram jugak?

yup DDR2,3,5 mempunyai speed yg berbeza,,yg paling laju DDR5 la...tp bkn tu saje...bit juga memainkan peranan juga...berserta dgn cip graphic card tu juga..

makne nye key notch die tetap sme lar...cume speed jer beza..ohh..

yup...ddr1..ddr2..now DDR5...upgradable...for fast...teknologi sentiasa meningkat

perbezaan penting yg di bandingkan antara smua Graphic card ->

[b]Memory Bandwidth:[/b] Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

[b]Texel Rate:[/b] Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

[b]Pixel Rate:[/b] Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

mine ddr3... tp 256bit... so mana ok yg skg.. ddr5 tp bit 128jerk

utk game zaman skrg. DDR/GDDR5 adalah sgt digalakkan

ddr5 blh masuk kt motherboard core 2 or core 2 duo?

boleh je janji psu power cukup and ko ada slot PCIE
