GeForce GTX 950M vs Radeon HD 6970

Intro

The GeForce GTX 950M uses a 28 nm design. nVidia has clocked the core speed at 914 MHz. The DDR3 memory works at a speed of 1000 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 6970, which features GPU clock speed of 880 MHz, and 2048 MB of GDDR5 RAM running at 1375 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
