GeForce GTX 285 1GB vs GeForce GTX 980M

Intro

The GeForce GTX 285 1GB makes use of a 55 nm design. nVidia has clocked the core frequency at 648 MHz. The GDDR3 RAM runs at a speed of 1242 MHz on this particular card. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 980M, which features a core clock speed of 1038 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 96 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M 100 Watts
GeForce GTX 285 1GB 204 Watts
Difference: 104 Watts (104%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 1GB should be 24% quicker than the GeForce GTX 980M in general, because of its higher data rate. (explain)

GeForce GTX 285 1GB 158976 MB/sec
GeForce GTX 980M 128000 MB/sec
Difference: 30976 (24%)

Texel Rate

The GeForce GTX 980M is quite a bit (approximately 92%) more effective at texture filtering than the GeForce GTX 285 1GB. (explain)

GeForce GTX 980M 99648 Mtexels/sec
GeForce GTX 285 1GB 51840 Mtexels/sec
Difference: 47808 (92%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 980M is the winner, and very much so. (explain)

GeForce GTX 980M 66432 Mpixels/sec
GeForce GTX 285 1GB 20736 Mpixels/sec
Difference: 45696 (220%)

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 information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the 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 clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
