GeForce GT 240 GDDR5 1GB vs GeForce GT 340
Intro
The GeForce GT 240 GDDR5 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory works at a speed of 850 MHz on this particular card. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the GeForce GT 340, which makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory is set to run at a speed of 850 MHz on this specific card. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
| GeForce GT 340 |
|
69 Watts |
| GeForce GT 240 GDDR5 1GB |

Memory Bandwidth
Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)
Texel Rate
Both cards have exactly the same texel rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have the exact same pixel fill rate, so in theory they should perform equally good at at FSAA, and be able to handle 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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
