GeForce GTX 950M vs Radeon HD 5570

Intro

Compare that to the Radeon HD 5570, which uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this particular model. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GTX 950M		55 Watts
	Difference: 12 Watts (28%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950M should be a small bit faster than the Radeon HD 5570 overall. (explain)

GeForce GTX 950M		32000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The GeForce GTX 950M should be a lot (approximately 181%) better at texture filtering than the Radeon HD 5570. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 23560 (181%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 950M is the winner, by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 9424 (181%)

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 over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
