Radeon HD 4870 X2 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has set the core frequency at 1717 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this particular card. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Radeon RX 5500 XT		229376 MB/sec
	Difference: 1024 (0%)

Texel Rate

The Radeon RX 5500 XT should be much (about 152%) more effective at anisotropic filtering than the Radeon HD 4870 X2. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon HD 4870 X2		60000 Mtexels/sec
	Difference: 91096 (152%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5500 XT is superior to the Radeon HD 4870 X2, by far. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon HD 4870 X2		24000 Mpixels/sec
	Difference: 30944 (129%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core 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 record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
