GeForce GTX 295 vs Radeon RX 480

Intro

Compare all that to the Radeon RX 480, which has clock speeds of 1120 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480		150 Watts
GeForce GTX 295		289 Watts
	Difference: 139 Watts (93%)

Memory Bandwidth

In theory, the Radeon RX 480 is 17% quicker than the GeForce GTX 295 in general, due to its higher data rate. (explain)

Radeon RX 480		262144 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 38368 (17%)

Texel Rate

The Radeon RX 480 should be much (approximately 75%) more effective at AF than the GeForce GTX 295. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 69120 (75%)

Pixel Rate

The Radeon RX 480 will be a little bit (about 11%) better at anti-aliasing than the GeForce GTX 295, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 480		35840 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 3584 (11%)

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 data (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses 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 per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, 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 maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
