GeForce GT 240 GDDR5 vs Radeon HD 4670 512MB

Intro

The GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this particular model. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4670 512MB, which comes with clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GT 240 GDDR5 should be quite a bit faster than the Radeon HD 4670 512MB overall. (explain)

GeForce GT 240 GDDR5 54400 MB/sec
Radeon HD 4670 512MB 32000 MB/sec
Difference: 22400 (70%)

Texel Rate

The Radeon HD 4670 512MB should be quite a bit (approximately 36%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)

Radeon HD 4670 512MB 24000 Mtexels/sec
GeForce GT 240 GDDR5 17600 Mtexels/sec
Difference: 6400 (36%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 4670 512MB is the winner, by a large margin. (explain)

Radeon HD 4670 512MB 6000 Mpixels/sec
GeForce GT 240 GDDR5 4400 Mpixels/sec
Difference: 1600 (36%)

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 (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 potential to reach the maximum fill rate.
