GeForce GTX 460 2GB vs GeForce GTX 950

Intro

The GeForce GTX 460 2GB uses a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Compare those specs to the GeForce GTX 950, which features a clock speed of 1024 MHz and a GDDR5 memory frequency of 1652 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 768 SPUs, 48 TAUs, and 32 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
