GeForce 9500 GT DDR2 vs GeForce GTS 450 1GB

Intro

Compare all that to the GeForce GTS 450 1GB, which comes with core clock speeds of 783 MHz on the GPU, and 902 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth

As far as performance goes, the GeForce GTS 450 1GB should in theory be much superior to the GeForce 9500 GT DDR2 in general. (explain)

GeForce GTS 450 1GB		57728 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 41728 (261%)

Texel Rate

The GeForce GTS 450 1GB will be quite a bit (more or less 185%) faster with regards to texture filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTS 450 1GB		25056 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 16256 (185%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTS 450 1GB is the winner, and very much so. (explain)

GeForce GTS 450 1GB		12528 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 8128 (185%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the 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 amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
