GeForce GTX 460 vs GeForce GTX 460 (OEM)

Intro

Compare all of that to the GeForce GTX 460 (OEM), which features clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 460 (OEM) should perform much faster than the GeForce GTX 460 overall. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 22400 (26%)

Texel Rate

The GeForce GTX 460 is a bit (about 4%) faster with regards to anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 460		37800 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 1400 (4%)

Pixel Rate

The GeForce GTX 460 (OEM) should be much (more or less 28%) faster with regards to AA than the GeForce GTX 460, and also should be capable of handling higher resolutions better. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 4600 (28%)

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 largest amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
