GeForce 920M vs GeForce GT 240 GDDR5

Intro

The GeForce 920M has core clock speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Compare all that to the GeForce GT 240 GDDR5, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory works at a speed of 850 MHz on this card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GT 240 GDDR5 should theoretically be quite a bit superior to the GeForce 920M overall. (explain)

GeForce GT 240 GDDR5 54400 MB/sec
GeForce 920M 14400 MB/sec
Difference: 40000 (278%)

Texel Rate

The GeForce 920M should be a lot (approximately 73%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

GeForce 920M 30528 Mtexels/sec
GeForce GT 240 GDDR5 17600 Mtexels/sec
Difference: 12928 (73%)

Pixel Rate

The GeForce 920M will be much (approximately 73%) faster with regards to AA than the GeForce GT 240 GDDR5, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce 920M 7632 Mpixels/sec
GeForce GT 240 GDDR5 4400 Mpixels/sec
Difference: 3232 (73%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
