GeForce GTX 965M vs Radeon HD 3870 1GB

Intro

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

Compare all of that to the Radeon HD 3870 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 775 MHz. The GDDR4 RAM is set to run at a speed of 1125 MHz on this specific card. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
