GeForce GTX 295 vs Radeon RX 480

Intro

The GeForce GTX 295 features clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

Compare that to the Radeon RX 480, which comes with a core clock speed of 1120 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 TAUs, and 32 Raster Operation 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

The Radeon RX 480 should theoretically be a small bit faster than the GeForce GTX 295 in general. (explain)

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

Texel Rate

The Radeon RX 480 will be a lot (approximately 75%) faster with regards to 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 is just a bit (approximately 11%) more effective at full screen anti-aliasing than the GeForce GTX 295, and will be capable of handling higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at 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 can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
