GeForce GTX 960M vs Radeon HD 5570

Intro

Compare all of that to the Radeon HD 5570, which comes with a clock frequency of 650 MHz and a DDR3 memory frequency of 900 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GTX 960M		65 Watts
	Difference: 22 Watts (51%)

Memory Bandwidth

Theoretically, the GeForce GTX 960M should perform much faster than the Radeon HD 5570 overall. (explain)

GeForce GTX 960M		64000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The GeForce GTX 960M will be a lot (more or less 237%) more effective at anisotropic filtering than the Radeon HD 5570. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 30840 (237%)

Pixel Rate

The GeForce GTX 960M will be quite a bit (about 237%) faster with regards to full screen anti-aliasing than the Radeon HD 5570, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 12336 (237%)

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 data (in units of megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
