GeForce 9800 GTX vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which features a clock frequency of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 ROPs.

GeForce 9800 GTX		70400 MB/sec
	Difference: 388352 (552%)

Texel Rate

The Radeon RX 5700 XT is quite a bit (approximately 494%) more effective at texture filtering than the GeForce 9800 GTX. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce 9800 GTX		43200 Mtexels/sec
	Difference: 213600 (494%)

Pixel Rate

The Radeon RX 5700 XT will be a lot (more or less 851%) more effective at FSAA than the GeForce 9800 GTX, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 91920 (851%)

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 max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
