Geforce GTX 760 vs Radeon HD 4670 1GB


Intro

The Geforce GTX 760 features a clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It features 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon HD 4670 1GB, which uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM runs at a speed of 1100 MHz on this card. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
