GeForce GT 230 vs Geforce GTX 760

Intro

Compare those specifications to the Geforce GTX 760, which comes with a core clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is made up of 1152 SPUs, 96 TAUs, 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

Theoretically speaking, the Geforce GTX 760 should be 401% faster than the GeForce GT 230 in general, because of its greater data rate. (explain)

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

Texel Rate

The Geforce GTX 760 is quite a bit (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

The Geforce GTX 760 will be a lot (about 613%) more effective at anti-aliasing than the GeForce GT 230, and also will be able to handle higher resolutions more effectively. (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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
