GeForce GTX 470 vs Radeon RX 460 2GB

Intro

The GeForce GTX 470 comes with a clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also features a 320-bit bus, and uses a 40 nm design. It features 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

Compare all that to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this specific card. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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