GeForce GTX 965M vs Radeon HD 4730

Intro

The GeForce GTX 965M uses a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this card. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Compare those specifications to the Radeon HD 4730, which features GPU clock speed of 700 MHz, and 512 MB of GDDR5 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 TAUs, and 8 ROPs.

GeForce GTX 965M 60 Watts
Radeon HD 4730 140 Watts
Difference: 80 Watts (133%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 965M will be 11% quicker than the Radeon HD 4730 overall, because of its higher bandwidth. (explain)

GeForce GTX 965M 64000 MB/sec
Radeon HD 4730 57600 MB/sec
Difference: 6400 (11%)

Texel Rate

The GeForce GTX 965M should be a lot (about 170%) more effective at AF than the Radeon HD 4730. (explain)

GeForce GTX 965M 60416 Mtexels/sec
Radeon HD 4730 22400 Mtexels/sec
Difference: 38016 (170%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 965M is superior to the Radeon HD 4730, and very much so. (explain)

GeForce GTX 965M 30208 Mpixels/sec
Radeon HD 4730 5600 Mpixels/sec
Difference: 24608 (439%)

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 max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, 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 maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
