GeForce GTX 295 vs Radeon RX 480 4GB

Intro

The GeForce GTX 295 has a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit memory bus, and uses a 55 nm design. It features 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

Compare all that to the Radeon RX 480 4GB, which comes with GPU clock speed of 1120 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480 4GB 150 Watts
GeForce GTX 295 289 Watts
Difference: 139 Watts (93%)

Memory Bandwidth

Theoretically, the Radeon RX 480 4GB should perform a small bit faster than the GeForce GTX 295 in general. (explain)

Radeon RX 480 4GB 229376 MB/sec
GeForce GTX 295 223776 MB/sec
Difference: 5600 (3%)

Texel Rate

The Radeon RX 480 4GB should be quite a bit (about 75%) more effective at texture filtering than the GeForce GTX 295. (explain)

Radeon RX 480 4GB 161280 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 69120 (75%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 480 4GB is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 480 4GB 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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
