GeForce GT 240 GDDR5 vs GeForce GT 430 1GB

Intro

The GeForce GT 240 GDDR5 features a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 memory runs at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 ROPs.

Compare those specs to the GeForce GT 430 1GB, which has clock speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB 60 Watts
GeForce GT 240 GDDR5 70 Watts
Difference: 10 Watts (17%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 240 GDDR5 is 89% faster than the GeForce GT 430 1GB in general, because of its greater data rate. (explain)

GeForce GT 240 GDDR5 54400 MB/sec
GeForce GT 430 1GB 28800 MB/sec
Difference: 25600 (89%)

Texel Rate

The GeForce GT 240 GDDR5 should be quite a bit (approximately 57%) faster with regards to anisotropic filtering than the GeForce GT 430 1GB. (explain)

GeForce GT 240 GDDR5 17600 Mtexels/sec
GeForce GT 430 1GB 11200 Mtexels/sec
Difference: 6400 (57%)

Pixel Rate

The GeForce GT 240 GDDR5 should be quite a bit (approximately 57%) better at AA than the GeForce GT 430 1GB, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GT 240 GDDR5 4400 Mpixels/sec
GeForce GT 430 1GB 2800 Mpixels/sec
Difference: 1600 (57%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
