GeForce GTX 480 vs Radeon R9 M390X

Intro

The GeForce GTX 480 features clock speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs along with 60 Texture Address Units and 48 Rasterization Operator Units.

Compare those specs to the Radeon R9 M390X, which uses a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest 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 card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
