GeForce GTX 950M vs Radeon RX 5700

Intro

Compare all that to the Radeon RX 5700, which has a core clock speed of 1465 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 950M		32000 MB/sec
	Difference: 426752 (1334%)

Texel Rate

The Radeon RX 5700 will be a lot (approximately 477%) faster with regards to texture filtering than the GeForce GTX 950M. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 174400 (477%)

Pixel Rate

The Radeon RX 5700 is quite a bit (about 541%) more effective at anti-aliasing than the GeForce GTX 950M, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 79136 (541%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
