GeForce GT 240 GDDR5 vs GeForce GTS 450

Intro

Compare all of that to the GeForce GTS 450, which features core clock speeds of 783 MHz on the GPU, and 902 MHz on the 512 MB of GDDR5 RAM. It features 192 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5		70 Watts
GeForce GTS 450		106 Watts
	Difference: 36 Watts (51%)

Memory Bandwidth

Theoretically speaking, the GeForce GTS 450 is 6% faster than the GeForce GT 240 GDDR5 overall, due to its greater data rate. (explain)

GeForce GTS 450		57728 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 3328 (6%)

Texel Rate

The GeForce GTS 450 will be a lot (about 42%) better at AF than the GeForce GT 240 GDDR5. (explain)

GeForce GTS 450		25056 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 7456 (42%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTS 450 is superior to the GeForce GT 240 GDDR5, and very much so. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce GT 240 GDDR5		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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
