Difference between 128bits and 256bits?

Solved
DannyG7 -  
Hello everyone

I asked myself the question: one video card has 128 bits and the other has 256 bits.
Does it make a difference and what are the characteristics of these bits? I am showing you 2 video cards to compare

#1 the 256 bits: https://www.materiel.net/

#2 the 128 bits: https://www.materiel.net/

I would like your opinion on the two in terms of power and what the 256 bits does better than the other video card?

Configuration: Operating System Microsoft Windows 7 Ultimate
DirectX 11.0
Power Supply Antec TP Quatro 1000Watts
Processor Type AMD Atlon 64 x2 6000+ 3007mhz each core with 6mb cache
Motherboard Asus M3A78-T
System Memory 4G DDR2 800Mhz Kingstone
Video Card ATI Radeon HD 3300 Graphics (700 MB)
Monitor good news I found the thief and recovered my 22" HD Asus VH222-H
Floppy Disk Drive 1.44 mm
Hard Drive Maxtor 7Y250P0 (250 Go, 7200 RPM, Ultra-ATA/133)
Optical Drive HL-DT-ST DVD-RAM GH22NP20
Keyboard Standard keyboard 101/102 keys or Microsoft Natural keyboard
Mouse PS/2 compatible mouse
Game Controllers PC Microsoft joystick driver

    Hi,
    first, a 256-bit graphics card compared to a 128-bit one allows for:
    - better graphic representation (images, applications utilizing 3D)
    - a relieving of the processor from calculations related to display (equivalent speed gain in data processing and program execution)
    - a reduction in RAM consumption (additional RAM, smoothness regarding the execution of certain tasks)

    In order for the performance gain to be truly felt, it is necessary to associate applications that allow to fully utilize the capabilities of the graphics card (DIRECTX which includes direct draw, direct 3D...) for example.

      Alors parmi les 2, laquelle est la meilleure pour les jeux 3D ? Je me demande si ce serait mieux 256 bits et overclocker ou bien la 128 bits pour la rapidité d'exécution ?
      Je ne sais pas si 60 MHz va faire une grosse différence entre les 2 cartes :S

      the 256, OF COURSE, and you can configure it with utilities available online
      if you notice any representation defects, you shouldn't force yourself to use it overclocked (since it heats up faster when overclocked and therefore requires running it with a powerful fan, otherwise its lifespan will be even more reduced), reconfigure your card using these utilities
      here is an example link https://www.generation-nt.com/telecharger-371-2-carte-graphique.html?lg=&l=0
      NEVERTHELESS KEEP YOUR 128 CARD

      I don't have either of these two cards, they're for future purchases ^^ and I thought about everything for overclocking

      "Already, 256 bits for a graphics card compared to 128 allows:
      - better graphical representation (images, applications leveraging 3D)
      - offloading the processor regarding the calculations related to display that need to be performed (speed gain equivalent in data processing and program execution)
      - a reduction in RAM consumption (extra RAM, smoothness regarding the execution of certain tasks)

      For the performance gain to be felt, it needs to be associated with applications that can fully exploit the capabilities of the graphics card (DIRECTX which includes direct draw, direct 3D...) for example."

      Haven't you said a bit of nonsense? I feel like you didn't understand what he was saying in his message, so you just went off on a tangent. You seem to be thinking about the video memory built into graphics cards, while this is about memory bus width, meaning the amount of binary elements (0 or 1) that the bus can pass per cycle. Theoretically, a 256-bit bus should process twice as many elements per cycle as a 128-bit one. But things are more complex. If the HD8530 card is more powerful than the HD5770, it is not twice as powerful. Recently, we've seen ATI cards with a 128-bit bus being more powerful than some NVIDIA cards with a 256-bit bus. Things like the consumption you mention have no basis. Generally, graphics cards with a 128-bit bus consume less than those with a 256-bit bus. I’ll stop talking to avoid being too lengthy.

      See you!
