GeForce GTX 295 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 is 211% faster than the Radeon R9 M365X overall, because of its greater data rate. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 151776 (211%)

Texel Rate

The GeForce GTX 295 should be a lot (approximately 149%) better at AF than the Radeon R9 M365X. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 55160 (149%)

Pixel Rate

The GeForce GTX 295 should be much (about 118%) better at FSAA than the Radeon R9 M365X, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 17456 (118%)

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 max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
