GeForce GT 230 vs GeForce GTX 550 Ti

Intro

Compare all of that to the GeForce GTX 550 Ti, which has GPU core speed of 900 MHz, and 1024 MB of GDDR5 memory set to run at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 51 Watts (78%)

Memory Bandwidth

Performance-wise, the GeForce GTX 550 Ti should in theory be quite a bit better than the GeForce GT 230 overall. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 60096 (157%)

Texel Rate

The GeForce GTX 550 Ti will be much (about 227%) faster with regards to AF than the GeForce GT 230. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 20000 (227%)

Pixel Rate

The GeForce GTX 550 Ti should be much (more or less 391%) more effective at full screen anti-aliasing than the GeForce GT 230, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 17200 (391%)

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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
