GeForce GTX 295 vs Radeon RX 570

Intro

Compare that to the Radeon RX 570, which makes use of a 14 nm design. AMD has set the core speed at 1168 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

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

In theory, 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 will be quite a bit (about 62%) better at anisotropic filtering 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, but only just. (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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
