Radeon HD 7950 3GB vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which uses a 12 nm design. AMD has clocked the core speed at 1469 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this card. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Texel Rate

The Radeon RX 590 should be quite a bit (approximately 136%) better at texture filtering than the Radeon HD 7950 3GB. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon HD 7950 3GB		89600 Mtexels/sec
	Difference: 121936 (136%)

Pixel Rate

The Radeon RX 590 will be a lot (more or less 84%) more effective at FSAA than the Radeon HD 7950 3GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 590		47008 Mpixels/sec
Radeon HD 7950 3GB		25600 Mpixels/sec
	Difference: 21408 (84%)

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 max amount of information (counted in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of 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 a second.

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