GeForce GTX 965M vs Radeon HD 3870 1GB

Intro

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

Compare that to the Radeon HD 3870 1GB, which features GPU core speed of 775 MHz, and 1024 MB of GDDR4 memory set to run at 1125 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
