GeForce GTX 295 vs Radeon R9 M365X

Intro

Compare that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 295, in theory, should perform quite a bit faster than the Radeon R9 M365X in general. (explain)

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

Texel Rate

The GeForce GTX 295 should be quite a bit (about 149%) more effective at texture filtering than the Radeon R9 M365X. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 295 is a better choice, and very much so. (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 largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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