GeForce GTX 965M vs Radeon HD 4750

Intro

The GeForce GTX 965M makes use of a 28 nm design. nVidia has clocked the core frequency at 944 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4750, which comes with GPU clock speed of 730 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 128-bit bus. It also features 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

In theory, the GeForce GTX 965M should be 25% faster than the Radeon HD 4750 overall, because of its higher bandwidth. (explain)

GeForce GTX 965M 64000 MB/sec
Radeon HD 4750 51200 MB/sec
Difference: 12800 (25%)

Texel Rate

The GeForce GTX 965M will be much (about 159%) better at texture filtering than the Radeon HD 4750. (explain)

GeForce GTX 965M 60416 Mtexels/sec
Radeon HD 4750 23360 Mtexels/sec
Difference: 37056 (159%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 965M is the winner, and very much so. (explain)

GeForce GTX 965M 30208 Mpixels/sec
Radeon HD 4750 11680 Mpixels/sec
Difference: 18528 (159%)

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 (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 figure 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount 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 Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few 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.
