GeForce GT 230 vs Geforce GTX 760

Intro

Compare those specifications to the Geforce GTX 760, which comes with a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also is made up of 1152 Stream Processors, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
Geforce GTX 760		170 Watts
	Difference: 105 Watts (162%)

Memory Bandwidth

The Geforce GTX 760, in theory, should be a lot faster than the GeForce GT 230 overall. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 153856 (401%)

Texel Rate

The Geforce GTX 760 will be a lot (more or less 969%) more effective at anisotropic filtering than the GeForce GT 230. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 85280 (969%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 760 is a better choice, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 26960 (613%)

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 largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
