GeForce GTX 965M vs Radeon HD 4750

Intro

Compare those specs to the Radeon HD 4750, which makes use of a 40 nm design. AMD has clocked the core frequency at 730 MHz. The GDDR5 memory is set to run at a frequency of 800 MHz on this specific card. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 965M		60 Watts
Radeon HD 4750		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

In theory, the GeForce GTX 965M should perform a lot faster than the Radeon HD 4750 in general. (explain)

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

Texel Rate

The GeForce GTX 965M is quite a bit (about 159%) better at AF than the Radeon HD 4750. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 965M is a better choice, by far. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at 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 card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
