GeForce GTX 965M vs Radeon HD 5570

Intro

The GeForce GTX 965M makes use of a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular model. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 5570, which has a clock speed of 650 MHz and a DDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
