GeForce GTX 980M vs Radeon HD 4790

Intro

The GeForce GTX 980M comes with clock speeds of 1038 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1536 SPUs as well as 96 Texture Address Units and 64 ROPs.

Compare all that to the Radeon HD 4790, which uses a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR5 memory works at a speed of 800 MHz on this particular card. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

The GeForce GTX 980M will be much (approximately 419%) better at AF than the Radeon HD 4790. (explain)

GeForce GTX 980M 99648 Mtexels/sec
Radeon HD 4790 19200 Mtexels/sec
Difference: 80448 (419%)

Pixel Rate

The GeForce GTX 980M should be much (approximately 592%) faster with regards to anti-aliasing than the Radeon HD 4790, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 980M 66432 Mpixels/sec
Radeon HD 4790 9600 Mpixels/sec
Difference: 56832 (592%)

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 across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If 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 can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
