GeForce GTX 295 vs Radeon RX 470 4GB

Intro

Compare that to the Radeon RX 470 4GB, which comes with GPU core speed of 926 MHz, and 4096 MB of GDDR5 RAM running at 1650 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
GeForce GTX 295		289 Watts
	Difference: 169 Watts (141%)

Memory Bandwidth

Performance-wise, the GeForce GTX 295 should theoretically be a bit better than the Radeon RX 470 4GB overall. (explain)

GeForce GTX 295		223776 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 12576 (6%)

Texel Rate

The Radeon RX 470 4GB will be quite a bit (more or less 29%) better at anisotropic filtering than the GeForce GTX 295. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 26368 (29%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the Radeon RX 470 4GB, not by a very large margin though. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 2624 (9%)

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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated 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 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 most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
