GeForce GT 450 (OEM) vs Geforce GTX 760

Intro

Compare those specifications to the Geforce GTX 760, which has GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 256-bit bus. It also is comprised of 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
Geforce GTX 760		170 Watts
	Difference: 64 Watts (60%)

Memory Bandwidth

Theoretically, the Geforce GTX 760 should be much faster than the GeForce GT 450 (OEM) in general. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 96256 (100%)

Texel Rate

The Geforce GTX 760 should be much (more or less 396%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 75120 (396%)

Pixel Rate

If using 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 450 (OEM)		18960 Mpixels/sec
	Difference: 12400 (65%)

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 (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
