GeForce GTX 880M vs Radeon RX 460 2GB

Intro

The GeForce GTX 880M features a GPU clock speed of 954 MHz, and the 4096 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 460 2GB, which has a core clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen 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 number 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 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
