GeForce GTX 950M vs Radeon HD 5570

Intro

Compare all that to the Radeon HD 5570, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also features 400(80x5) Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth

The GeForce GTX 950M should theoretically perform a bit faster than the Radeon HD 5570 in general. (explain)

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

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 181%) faster with regards to anisotropic 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 using lots of anti-aliasing is important to you, then the GeForce GTX 950M is a better choice, and very much so. (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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
