GeForce GT 240 GDDR5 1GB vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which uses a 55 nm design. AMD has set the core frequency at 575 MHz. The DDR2 memory works at a frequency of 500 MHz on this specific model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

	Difference: 13000 (283%)

Pixel Rate

The GeForce GT 240 GDDR5 1GB should be much (approximately 91%) faster with regards to anti-aliasing than the Radeon HD 4350, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 2100 (91%)

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 megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics card can possibly record 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 card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
