VS

GeForce GTX 260 vs GeForce GTX 980M

Intro

The GeForce GTX 260 has core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 192 SPUs along with 64 Texture Address Units and 28 Rasterization Operator Units.

Compare that to the GeForce GTX 980M, which uses a 28 nm design. nVidia has set the core frequency at 1038 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this card. It features 1536 SPUs along with 96 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M 100 Watts
GeForce GTX 260 182 Watts
Difference: 82 Watts (82%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980M should be just a bit faster than the GeForce GTX 260 in general. (explain)

GeForce GTX 980M 128000 MB/sec
GeForce GTX 260 111888 MB/sec
Difference: 16112 (14%)

Texel Rate

The GeForce GTX 980M should be much (approximately 170%) faster with regards to AF than the GeForce GTX 260. (explain)

GeForce GTX 980M 99648 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 62784 (170%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 980M is a better choice, by far. (explain)

GeForce GTX 980M 66432 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 50304 (312%)

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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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