GeForce GT 240 GDDR5 1GB vs Radeon HD 6750 1GB

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 RAM runs at a speed of 850 MHz on this particular card. It features 96 SPUs as well as 32 TAUs and 8 ROPs.

Compare that to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific model. It features 720 SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5 1GB 70 Watts
Radeon HD 6750 1GB 86 Watts
Difference: 16 Watts (23%)

Memory Bandwidth

In theory, the Radeon HD 6750 1GB should perform just a bit faster than the GeForce GT 240 GDDR5 1GB in general. (explain)

Radeon HD 6750 1GB 64000 MB/sec
GeForce GT 240 GDDR5 1GB 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The Radeon HD 6750 1GB should be quite a bit (approximately 48%) faster with regards to AF than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon HD 6750 1GB 26100 Mtexels/sec
GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
Difference: 8500 (48%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is superior to the GeForce GT 240 GDDR5 1GB, and very much so. (explain)

Radeon HD 6750 1GB 11600 Mpixels/sec
GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
Difference: 7200 (164%)

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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
