Radeon HD 5670 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which uses a 12 nm design. AMD has set the core speed at 1469 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this specific card. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5670		61 Watts
Radeon RX 590		175 Watts
	Difference: 114 Watts (187%)

Memory Bandwidth

In theory, the Radeon RX 590 should be 310% quicker than the Radeon HD 5670 in general, because of its higher bandwidth. (explain)

Radeon RX 590		262144 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 198144 (310%)

Texel Rate

The Radeon RX 590 will be a lot (approximately 1265%) more effective at anisotropic filtering than the Radeon HD 5670. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 196036 (1265%)

Pixel Rate

The Radeon RX 590 will be a lot (more or less 658%) better at AA than the Radeon HD 5670, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 590		47008 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 40808 (658%)

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 (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 potential to get to the max fill rate.
