GeForce GTX 295 vs Radeon RX 470

Intro

Compare that to the Radeon RX 470, which comes with GPU core speed of 926 MHz, and 8192 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the GeForce GTX 295 should perform a bit faster than the Radeon RX 470 overall. (explain)

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

Texel Rate

The Radeon RX 470 will be much (approximately 29%) better at texture filtering than the GeForce GTX 295. (explain)

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

Pixel Rate

The GeForce GTX 295 is just a bit (about 9%) more effective at FSAA than the Radeon RX 470, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon RX 470		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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 max fill rate.
