GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 950

Intro

The GeForce 8600 GT 1GB GDDR3 has core speeds of 540 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specs to the GeForce GTX 950, which uses a 28 nm design. nVidia has clocked the core frequency at 1024 MHz. The GDDR5 memory is set to run at a speed of 1652 MHz on this particular model. It features 768 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
