GeForce GT 240 GDDR5 1GB vs Radeon HD 4790

Intro

The GeForce GT 240 GDDR5 1GB makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this card. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the Radeon HD 4790, which uses a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR5 memory works at a frequency of 800 MHz on this particular model. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 4790 should be a lot faster than the GeForce GT 240 GDDR5 1GB overall. (explain)

Radeon HD 4790 102400 MB/sec
GeForce GT 240 GDDR5 1GB 54400 MB/sec
Difference: 48000 (88%)

Texel Rate

The Radeon HD 4790 will be a bit (more or less 9%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon HD 4790 19200 Mtexels/sec
GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
Difference: 1600 (9%)

Pixel Rate

The Radeon HD 4790 will be a lot (more or less 118%) more effective at FSAA than the GeForce GT 240 GDDR5 1GB, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 4790 9600 Mpixels/sec
GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
Difference: 5200 (118%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 get to the max fill rate.
