GeForce GT 240 GDDR5 vs Radeon HD 6750 1GB

Intro

The GeForce GT 240 GDDR5 makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM works at a speed of 850 MHz on this model. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the Radeon HD 6750 1GB, which comes with core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 720 SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

GeForce GT 240 GDDR5 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The Radeon HD 6750 1GB is a lot (about 48%) better at AF than the GeForce GT 240 GDDR5. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6750 1GB is a better choice, by far. (explain)

Radeon HD 6750 1GB 11600 Mpixels/sec
GeForce GT 240 GDDR5 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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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