Radeon R7 250 vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which uses a 7 nm design. AMD has clocked the core frequency at 1670 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this model. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250		65 Watts
Radeon RX 5500		150 Watts
	Difference: 85 Watts (131%)

Memory Bandwidth

Performance-wise, the Radeon RX 5500 should in theory be a lot better than the Radeon R7 250 overall. (explain)

Radeon RX 5500		229376 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 155776 (212%)

Texel Rate

The Radeon RX 5500 is much (more or less 512%) better at AF than the Radeon R7 250. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 122960 (512%)

Pixel Rate

The Radeon RX 5500 should be quite a bit (more or less 568%) better at full screen anti-aliasing than the Radeon R7 250, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 45440 (568%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
