GeForce GTX 295 vs Radeon RX 570

Intro

Compare all that to the Radeon RX 570, which has a GPU core clock speed of 1168 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 570		150 Watts
GeForce GTX 295		289 Watts
	Difference: 139 Watts (93%)

Memory Bandwidth

Theoretically, the Radeon RX 570 should be a small bit faster than the GeForce GTX 295 in general. (explain)

Radeon RX 570		229376 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 5600 (3%)

Texel Rate

The Radeon RX 570 should be quite a bit (about 62%) better at AF than the GeForce GTX 295. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 57344 (62%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 570 is the winner, though not by far. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 5120 (16%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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