GeForce GTX 970 vs Radeon RX 480

Intro

The GeForce GTX 970 uses a 28 nm design. nVidia has set the core frequency at 1050 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this specific card. It features 1664 SPUs as well as 104 Texture Address Units and 64 Rasterization Operator Units.

Compare all that to the Radeon RX 480, which makes use of a 14 nm design. AMD has set the core speed at 1120 MHz. The GDDR5 RAM runs at a speed of 2000 MHz on this particular model. It features 2304 SPUs along with 144 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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