GeForce GT 310 vs Radeon HD 5670

Intro

Compare that to the Radeon HD 5670, which makes use of a 40 nm design. AMD has set the core frequency at 775 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific card. It features 400(80x5) SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
Radeon HD 5670		61 Watts
	Difference: 30 Watts (97%)

Memory Bandwidth

Performance-wise, the Radeon HD 5670 should theoretically be a lot better than the GeForce GT 310 in general. (explain)

Radeon HD 5670		64000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 5670 should be much (more or less 229%) faster with regards to anisotropic filtering than the GeForce GT 310. (explain)

Radeon HD 5670		15500 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 10788 (229%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5670 is a better choice, by far. (explain)

Radeon HD 5670		6200 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 3844 (163%)

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 largest amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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