VS

GeForce GTX 460 1GB vs GeForce GTX 460 SE

Intro

The GeForce GTX 460 1GB uses a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM runs at a frequency of 900 MHz on this card. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Compare all that to the GeForce GTX 460 SE, which comes with a GPU core clock speed of 650 MHz, and 1024 MB of GDDR5 RAM running at 850 MHz through a 256-bit bus. It also is made up of 288 SPUs, 48 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 SE 150 Watts
GeForce GTX 460 1GB 160 Watts
Difference: 10 Watts (7%)

Memory Bandwidth

In theory, the GeForce GTX 460 1GB will be 6% faster than the GeForce GTX 460 SE overall, due to its higher bandwidth. (explain)

GeForce GTX 460 1GB 115200 MB/sec
GeForce GTX 460 SE 108800 MB/sec
Difference: 6400 (6%)

Texel Rate

The GeForce GTX 460 1GB should be a lot (more or less 21%) better at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 460 1GB 37800 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 6600 (21%)

Pixel Rate

The GeForce GTX 460 1GB should be a little bit (about 4%) more effective at full screen anti-aliasing than the GeForce GTX 460 SE, and also will be capable of handling higher resolutions better. (explain)

GeForce GTX 460 1GB 21600 Mpixels/sec
GeForce GTX 460 SE 20800 Mpixels/sec
Difference: 800 (4%)

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 transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
