GeForce GTX 950 vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which has a clock frequency of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 1408 SPUs, 88 TAUs, and 32 ROPs.

GeForce GTX 950		49152 Mtexels/sec
	Difference: 97808 (199%)

Pixel Rate

The Radeon RX 5500 will be much (approximately 63%) better at AA than the GeForce GTX 950, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GTX 950		32768 Mpixels/sec
	Difference: 20672 (63%)

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 data (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
