GeForce GTX 295 vs Radeon R9 380 2G

Intro

The GeForce GTX 295 makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory runs at a frequency of 999 MHz on this particular model. It features 240 SPUs along with 80 TAUs and 28 Rasterization Operator Units.

Compare that to the Radeon R9 380 2G, which uses a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM works at a frequency of 1425 MHz on this specific card. It features 1792 SPUs along with 112 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 380 2G 190 Watts
GeForce GTX 295 289 Watts
Difference: 99 Watts (52%)

Memory Bandwidth

Theoretically, the GeForce GTX 295 should be a lot faster than the Radeon R9 380 2G overall. (explain)

GeForce GTX 295 223776 MB/sec
Radeon R9 380 2G 182400 MB/sec
Difference: 41376 (23%)

Texel Rate

The Radeon R9 380 2G is just a bit (approximately 18%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)

Radeon R9 380 2G 108640 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 16480 (18%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the Radeon R9 380 2G, not by a very large margin though. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon R9 380 2G 31040 Mpixels/sec
Difference: 1216 (4%)

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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
