GeForce GTS 150 vs GeForce GTX 470

Intro

The GeForce GTS 150 comes with a core clock frequency of 740 MHz and a GDDR3 memory speed of 500 MHz. It also makes use of a 256-bit bus, and makes use of a 55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare those specs to the GeForce GTX 470, which features a core clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also uses a 320-bit memory bus, and makes use of a 40 nm design. It is made up of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
