GeForce GTS 450 vs GeForce GTX 860M

Intro

The GeForce GTS 450 makes use of a 40 nm design. nVidia has clocked the core speed at 783 MHz. The GDDR5 memory works at a speed of 902 MHz on this model. It features 192 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare those specs to the GeForce GTX 860M, which has a GPU core clock speed of 797 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 1152 Stream Processors, 96 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
