GeForce GT 340 vs Radeon HD 5750 1GB

Intro

Compare all that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 RAM is set to run at a frequency of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Texel Rate

The Radeon HD 5750 1GB will be quite a bit (more or less 43%) more effective at texture filtering than the GeForce GT 340. (explain)

Radeon HD 5750 1GB		25200 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 7600 (43%)

Pixel Rate

The Radeon HD 5750 1GB is a lot (more or less 155%) better at FSAA than the GeForce GT 340, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 6800 (155%)

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 (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
