GeForce GTX 960M vs Radeon HD 5770

Intro

The GeForce GTX 960M makes use of a 28 nm design. nVidia has set the core frequency at 1096 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Compare that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a speed of 1200 MHz on this particular card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

GeForce GTX 960M 64000 MB/sec
Difference: 12800 (20%)

Texel Rate

The GeForce GTX 960M is a lot (more or less 29%) more effective at AF than the Radeon HD 5770. (explain)

GeForce GTX 960M 43840 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 9840 (29%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960M is superior to the Radeon HD 5770, by far. (explain)

GeForce GTX 960M 17536 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 3936 (29%)

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 megabytes per second) that can be transferred over 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. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
