I need to know the some vocabulary that they use for GPU specs.

I need to know what these mean and how they work.

1. GPCS / SMXS

2. CUDA CORES

3. TMUS

4. MEMORY BUS TYPE

5. MEMORY BANDWIDTH


(PLEASE TELL ME HOW THEY WORK NOT ONLY THEIR DEFINITIONS)

I'll do a couple.

Memory bandwidth is the amount of data the GPU memory (VRAM) can transfer in a second. Measured in GB/s. The more the merrier. GPU's need tons of bandwidth to feed the GPU core with data to process.

Bus type is just the width of the bus. 64-bit, 128-bit, 256-bit, 384-bit are all common bus widths now. They, along with the memory type and speed, effect the memory bandwidth. When talking about GDDR5 (the standard for all decent cards now), bigger bus width is always better.

1. SM mean Stream Multiprocessors, when they updated it they now called SMX. An SMX has a polymorph, instruction cache, CUDA cores, and etc.

2. CUDA is Nvidia's computer architecture (computer engine they use). CUDA cores refer to how many of that is in the architecture.

3. TMUS is Textured Mapping Units. It rotates and resizes a 3D object

4. From GPUreview.com, "On the card pages we first display the type of memory bus, and then the overall size in parentheses. The 'type' of bus refers to how the bus is broken up internally to better handle smaller chunks of data. For example the 7600 GT has a 64x2 memory bus, meaning it can process one 128bit chunk per clock, or two 64bit chunks. This segmenting makes the fetching of smaller chunks of data much more efficient since otherwise an entire clock cycle would be taken for a 64bit chunk"

5: Also from GPUreview.com, "Short version: The speed at which the card can access the memory" "Long Version: Memory bandwidth is equal to the size of the memory bus multiplied by the speed at which the memory is clocked.
The higher the memory bandwidth, the better the card will be able to handle large textures and anti-aliasing and anisotropic filtering. Not to say that you don't need a lot of memory bandwidth if you don't want to use these features, you still do. Memory bandwidth is important in nearly every part of graphics processing.
The amount and speed of the memory matter very little in comparison to the overall memory bandwidth. If you want a card with good memory, this number says it all."

Thank you very much for your time!
