GeForce GTS 450 vs GeForce GTX 260

Intro

The GeForce GTS 450 uses a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 memory works at a frequency of 902 MHz on this particular model. It features 192 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare all of that to the GeForce GTX 260, which has a core clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit bus, and makes use of a 65 nm design. It is made up of 192 SPUs, 64 TAUs, and 28 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

An useful article, I was searching for something like this as I've got a 260 and a nice offer for a gts450
After having a look at the article, I will continue with my 260..
