GeForce GTX 295 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular model. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GTX 295 should in theory perform quite a bit faster than the Radeon RX 460 in general. (explain)

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

Texel Rate

The GeForce GTX 295 should be quite a bit (about 51%) more effective at anisotropic filtering than the Radeon RX 460. (explain)

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

Pixel Rate

The GeForce GTX 295 is quite a bit (about 85%) better at AA than the Radeon RX 460, and should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon RX 460		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: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 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 of the card by the core speed of the chip. The higher this number, the better the video 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 chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
