The DEC VAX supported operations on 128-bit integer ('O' or octaword) and 128-bit floating-point ('H-float' or HFLOAT) datatypes. Support for such operations was an upgrade option rather than being a standard feature. Since the VAX's registers were 32 bits wide, a 128-bit operation used four consecutive registers or four longwords in memory.
The ability to build a system with just one graphics card, and still have it be feature-complete for the time, made the RIVA 128 a lower-cost high-performance solution. Nvidia equipped the RIVA 128 with 4 MiB of SGRAM, a new memory technology for the time, clocked at 100 MHz and connected to the graphics processor via a 128-bit memory bus. [2]
Bus interface – Bus by which the graphics processor is attached to the system (typically an expansion slot, such as PCI, AGP, or PCI-Express). Memory – The amount of graphics memory available to the processor. SM Count – Number of streaming multiprocessors. [1]
The Radeon HD 3800 series was based on the codenamed RV670 GPU, packed 666 million transistors on a 55 nm fabrication process and had a die size at 192 mm 2, with the same 64 shader clusters as the R600 core, but the memory bus width was reduced to 256 bits.
Components of a GPU. A graphics processing unit (GPU) is a specialized electronic circuit initially designed for digital image processing and to accelerate computer graphics, being present either as a discrete video card or embedded on motherboards, mobile phones, personal computers, workstations, and game consoles.
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
The Imagine 128 GPU introduced a full 128-bit graphics processor—GPU, internal processor bus, and memory bus were all 128 bits. However, there was no, or very little, hardware support for 3D graphics operations. [15] The Imagine 128-II added Gouraud shading, 32-bit Z-buffering, double display buffering, and a 256-bit video rendering engine. [16]
In computing, quadruple precision (or quad precision) is a binary floating-point–based computer number format that occupies 16 bytes (128 bits) with precision at least twice the 53-bit double precision. This 128-bit quadruple precision is designed not only for applications requiring results in higher than double precision, [1] but also, as a ...
