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 clocked the core speed at 550 MHz. The GDDR5 memory works at a frequency of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 ROPs.

Compare all that to the Radeon HD 4790, which features a core clock frequency of 600 MHz and a GDDR5 memory speed of 800 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 4790, in theory, 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 just a bit (more or less 9%) faster with regards to 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

If running with a high screen resolution is important to you, then the Radeon HD 4790 is a better choice, by a large margin. (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 largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
