Radeon HD 4730 vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which features a core clock speed of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 4730		57600 MB/sec
	Difference: 57088 (99%)

Texel Rate

The Radeon RX 550 will be much (more or less 57%) more effective at texture filtering than the Radeon HD 4730. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 12800 (57%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 550 is superior to the Radeon HD 4730, and very much so. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 12000 (214%)

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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
