GeForce 8600 GT 512MB DDR2 vs GeForce GTX 950

Intro

The GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 RAM is set to run at a speed of 400 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare that to the GeForce GTX 950, which has clock speeds of 1024 MHz on the GPU, and 1652 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs along with 48 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends 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.
