GeForce GT 240 GDDR5 vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which features a clock speed of 650 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is comprised of 288 SPUs, 48 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5		70 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 80 Watts (114%)

Memory Bandwidth

Performance-wise, the GeForce GTX 460 SE should in theory be a lot superior to the GeForce GT 240 GDDR5 overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 54400 (100%)

Texel Rate

The GeForce GTX 460 SE is quite a bit (more or less 77%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 13600 (77%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 SE is the winner, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 16400 (373%)

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 data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
