GeForce GTX 295 vs Radeon RX 570

Intro

Compare those specifications to the Radeon RX 570, which makes use of a 14 nm design. AMD has set the core frequency at 1168 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 570 should perform a 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 much (about 62%) faster with regards to texture filtering than the GeForce GTX 295. (explain)

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

Pixel Rate

The Radeon RX 570 is a little bit (about 16%) more effective at full screen anti-aliasing than the GeForce GTX 295, and also will be capable of handling higher resolutions without losing too much performance. (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 (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
