GeForce GTX 460 2GB vs GeForce GTX 980M

Intro

The GeForce GTX 460 2GB uses a 40 nm design. nVidia has set the core speed at 675 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Compare that to the GeForce GTX 980M, which comes with a GPU core clock speed of 1038 MHz, and 4096 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 TAUs, and 64 Raster Operation Units.

GeForce GTX 460 2GB 115200 MB/sec
Difference: 12800 (11%)

Texel Rate

The GeForce GTX 980M will be much (more or less 164%) better at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX 980M 99648 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 61848 (164%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 980M is superior to the GeForce GTX 460 2GB, and very much so. (explain)

GeForce GTX 980M 66432 Mpixels/sec
GeForce GTX 460 2GB 21600 Mpixels/sec
Difference: 44832 (208%)

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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write 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 clock speed of the card. ROPs (Raster Operations Pipelines - also 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, 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.
