GeForce GTX 295 vs Radeon RX 590

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX 295		289 Watts
	Difference: 114 Watts (65%)

Memory Bandwidth

In theory, the Radeon RX 590 should be 17% quicker than the GeForce GTX 295 overall, because of its higher bandwidth. (explain)

Radeon RX 590		262144 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 38368 (17%)

Texel Rate

The Radeon RX 590 should be quite a bit (approximately 130%) better at AF 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 will be quite a bit (about 46%) better at FSAA than the GeForce GTX 295, and also should be able to handle higher screen resolutions better. (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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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