GeForce GTX 960M vs Radeon R9 M275X

Intro

The GeForce GTX 960M has a core clock frequency of 1096 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Compare all that to the Radeon R9 M275X, which uses a 28 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
