GeForce GTX 295 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which features core speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

GeForce GTX 295		223776 MB/sec
	Difference: 38368 (17%)

Texel Rate

The Radeon RX 590 is quite a bit (approximately 130%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 119376 (130%)

Pixel Rate

The Radeon RX 590 is much (about 46%) faster with regards to full screen anti-aliasing than the GeForce GTX 295, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 14752 (46%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 in one second. This 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
