Radeon HD 4870 1GB vs Radeon RX 550

Intro

The Radeon HD 4870 1GB uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory runs at a speed of 900 MHz on this model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare all that to the Radeon RX 550, which makes use of a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550 50 Watts
Radeon HD 4870 1GB 150 Watts
Difference: 100 Watts (200%)

Memory Bandwidth

In theory, the Radeon HD 4870 1GB should perform just a bit faster than the Radeon RX 550 overall. (explain)

Radeon HD 4870 1GB 115200 MB/sec
Radeon RX 550 114688 MB/sec
Difference: 512 (0%)

Texel Rate

The Radeon RX 550 will be a little bit (approximately 17%) better at anisotropic filtering than the Radeon HD 4870 1GB. (explain)

Radeon RX 550 35200 Mtexels/sec
Radeon HD 4870 1GB 30000 Mtexels/sec
Difference: 5200 (17%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 550 is a better choice, and very much so. (explain)

Radeon RX 550 17600 Mpixels/sec
Radeon HD 4870 1GB 12000 Mpixels/sec
Difference: 5600 (47%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
