a 128 bit interface at 1000mhz has the same bandwidth of a 256bit interface at 500mhz. Newer cards that use 128bit ram often use ddr5 which has 2 x the bandwidth per clock cycle of ddr3 or 2, therefore cancelling out the fact that they have 128bit vs a ddr2 or 3 256 bit card.
Both 128- and 256-bit graphics cards are suitable for the vast majority of users. They are more than adequate for basic computing, and also for budget gaming and general use of 3D graphics packages like 3ds Max and Maya.
A graphics card that has a pathway 128 bits wide between its on-board processor and memory (video RAM).
so a 64 bit card can do 64 bits on a clock cycle a 128 bit can do twice as much per the same clock cycle. so if you had two gpu with the same gpu chip but one was 64 bit and the other had 128 bit bus the card with the larger bus would be faster.
Generally speaking, the bit-width of a GPU refers to the width of the memory bus. A higher memory bus width means that more data can be transferred between the memory and the graphics processor, running at the same speed as the lower bus width.
all combine to give you the total memory throughput that the card can sustain -- so a card with higher speed DDR5 RAM and a 128 bit bus can be faster than a 256 bit bus card based on slower speed DDR3 ram - but if all other things are the same then a 256 bit bus is better than a 128 bit bus since it can handle twice as ...
amount of bits does not dictate a graphics cards performance, there are things like GPU core speed/shaders/texture units/.
It doesn't matter if you have a 32 bit or 64 bit OS, at least in your context of being able to use a graphics card. However a 64 bit OS will yield better performance on many new games primarily because you can have more than 4GB of system memory.
The GDDR5 uses 1.5V, and the GDDR6 uses 1.35V or 1.25V at reduced data rates. As expected, the GDDR6 offers higher transfer speeds – 14 Gbps to 16 Gbps, while the GDDR5 has speeds of up to 8 Gbps.
a 192-bit interface is quite low for a high-end GPU, however the memory clock makes up for it. The Radeon 7870 only has 4800 MHz memory clock, while the GTX 660 ti has 6008 MHz memory clock. The GTX 660 ti is the better performing GPU. Its performance is overall better than the Radeon 7870.
A 128-bit processor may never occur because there is no practical reason for doubling the basic register size. One of the reasons for migrating from 32-bit to 64-bit computers was memory (RAM) addressing; however, we only need a few more bits beyond 32 for all practical purposes (see binary values).
8-bit color graphics are a method of storing image information in a computer's memory or in an image file, so that each pixel is represented by 8 bits (1 byte). The maximum number of colors that can be displayed at any one time is 256 or 28.
GPUs contain a mix of 32bit and 64bit capability. I would suggest you read any of the gpu architecture whitepapers to learn some of the things that are natively supported at 32 bits and some of the things that can be handled at 64-bit width.
GPU memory bandwidth is a measure of the data transfer speed between a GPU and the system across a bus, such as PCI Express (PCIe) or Thunderbolt. It's important to consider the bandwidth of each GPU in a system when developing your high-performance Metal apps.
A 32-bit system can access 232 memory addresses, i.e., 4 GB of RAM or physical memory; ideally, it can also access more than 4 GB of RAM. A 64-bit system can access 264 memory addresses, i.e., actually 18-Quintillion bytes of RAM. In short, any amount of memory greater than 4 GB can be easily handled by it.
We recommend a graphics card with at least 6-8GB of VRAM and a decent amount of processing power for editing 1080p or 2160p footage on a Full-HD timeline.
The answer to this question depends on whether or not the VRAM has the same memory bus. If they do, then the GDDR6 will offer double the memory speed and bandwidth of the GDDR5 VRAM.
DDR5 provides twice the bandwidth and density of DDR4 while reducing power consumption. Higher bandwidth translates to faster processing for memory-intensive applications such as games, video and image editors, 3D tools, and browsers.
A 128-bit connection means how many BITS of data can be on the GPU to Video Memory connection at any one time; you can think of it simply in how many wires (or traces) connect the memory to the GPU.
8-bit graphics refers to the capability of every pixel to use 8 bits for storing the amount of colors that can be displayed. In a nutshell, 8-bit graphics refers to maximum 256 colors that can be displayed, whereas 16 bit means 65,536 colors and 34 bit means 16,777,215 colors.
In computer architecture, 256-bit integers, memory addresses, or other data units are those that are 256 bits (32 octets) wide. Also, 256-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.
Support for all-new NVIDIA SHIELD, the first Android TV device featuring a 64-bit ARM processor, NVIDIA® Tegra® X1 64-bit with the latest quad-core ARM CPU and NVIDIA Maxwell™ PC Graphics architecture.
The way it works is quite simply the bus width pretty much controls the number of memory chips that can be used on the card. A GPU with 256-bit bus has 8 memory chips minimum, since each memory chip have a 32-bit wide bus. Some cards with double the memory amount will have 16 memory chips.
