Radeon R7 250X vs Radeon RX 5500

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
Radeon RX 5500		150 Watts
	Difference: 55 Watts (58%)

Memory Bandwidth

The Radeon RX 5500 should in theory perform quite a bit faster than the Radeon R7 250X overall. (explain)

Radeon RX 5500		229376 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 should be a lot (approximately 267%) better at anisotropic filtering than the Radeon R7 250X. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 106960 (267%)

Pixel Rate

The Radeon RX 5500 should be much (about 234%) more effective at AA than the Radeon R7 250X, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 37440 (234%)

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 maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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 maximum fill rate.
