GeForce GT 230 vs GeForce GT 240 GDDR5 1GB

Intro

Compare all of that to the GeForce GT 240 GDDR5 1GB, which features clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
GeForce GT 240 GDDR5 1GB		70 Watts
	Difference: 5 Watts (8%)

Memory Bandwidth

As far as performance goes, the GeForce GT 240 GDDR5 1GB should theoretically be much superior to the GeForce GT 230 overall. (explain)

GeForce GT 240 GDDR5 1GB		54400 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 16000 (42%)

Texel Rate

The GeForce GT 240 GDDR5 1GB should be a lot (about 100%) better at texture filtering than the GeForce GT 230. (explain)

GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 8800 (100%)

Pixel Rate

Both cards have exactly the same pixel rate, so theoretically they should be equally good at at FSAA, and be capable of handling the same screen resolutions. (explain)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
