GeForce GTX 960M vs Radeon HD 4750

Intro

The GeForce GTX 960M comes with a GPU core speed of 1096 MHz, and the 2048 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the Radeon HD 4750, which features GPU core speed of 730 MHz, and 512 MB of GDDR5 memory set to run at 800 MHz through a 128-bit bus. It also features 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

Radeon HD 4750 23360 Mtexels/sec
Difference: 20480 (88%)

Pixel Rate

The GeForce GTX 960M will be a lot (about 50%) better at anti-aliasing than the Radeon HD 4750, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 960M 17536 Mpixels/sec
Radeon HD 4750 11680 Mpixels/sec
Difference: 5856 (50%)

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 information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
