GeForce GTS 150 vs GeForce GTX 465

Intro

The GeForce GTS 150 comes with a GPU core speed of 740 MHz, and the 1024 MB of GDDR3 memory is set to run at 500 MHz through a 256-bit bus. It also features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory is set to run at a speed of 802 MHz on this card. It features 352 SPUs along with 44 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
