GeForce GTX 860M vs Radeon HD 5770

Intro

The GeForce GTX 860M features a GPU core clock speed of 797 MHz, and the 4096 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also features 1152 Stream Processors, 96 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon HD 5770, which features GPU clock speed of 850 MHz, and 1024 MB of GDDR5 RAM set to run at 1200 MHz through a 128-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

GeForce GTX 860M 64000 MB/sec
Difference: 12800 (20%)

Texel Rate

The GeForce GTX 860M is quite a bit (about 125%) better at texture filtering than the Radeon HD 5770. (explain)

GeForce GTX 860M 76512 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 42512 (125%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 5770 is the winner, though only just barely. (explain)

Radeon HD 5770 13600 Mpixels/sec
GeForce GTX 860M 12752 Mpixels/sec
Difference: 848 (7%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
