GeForce GTX 460 (OEM) vs Radeon HD 5670

Intro

Compare those specs to the Radeon HD 5670, which makes use of a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this card. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5670		61 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 89 Watts (146%)

Memory Bandwidth

In theory, the GeForce GTX 460 (OEM) will be 70% quicker than the Radeon HD 5670 in general, because of its greater data rate. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 44800 (70%)

Texel Rate

The GeForce GTX 460 (OEM) is a lot (more or less 135%) more effective at texture filtering than the Radeon HD 5670. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 20900 (135%)

Pixel Rate

The GeForce GTX 460 (OEM) should be quite a bit (about 235%) faster with regards to full screen anti-aliasing than the Radeon HD 5670, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 14600 (235%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result 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, 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 is worked out by multiplying the total amount of texture units 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 filling the screen with pixels (the image). The actual pixel output 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 maximum fill rate.
