GeForce 8800 GT 256MB vs Radeon R7 M265

Intro

The GeForce 8800 GT 256MB comes with core clock speeds of 600 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 memory. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Compare all of that to the Radeon R7 M265, which uses a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 memory works at a speed of 1000 MHz on this specific card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units 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 amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
