GeForce GTX 295 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which features a core clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 295		289 Watts
	Difference: 214 Watts (285%)

Memory Bandwidth

In theory, the GeForce GTX 295 should be 100% faster than the Radeon RX 460 2GB overall, due to its higher bandwidth. (explain)

GeForce GTX 295		223776 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 111776 (100%)

Texel Rate

The GeForce GTX 295 will be much (more or less 51%) faster with regards to AF than the Radeon RX 460 2GB. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 31120 (51%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 295 is superior to the Radeon RX 460 2GB, and very much so. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 14816 (85%)

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 megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, 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 number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
