GeForce GTX 280 vs Radeon R9 M365X

Intro

Compare those specifications 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 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 280 should in theory be quite a bit better than the Radeon R9 M365X overall. (explain)

GeForce GTX 280		141696 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 69696 (97%)

Texel Rate

The GeForce GTX 280 is a lot (about 30%) better at AF than the Radeon R9 M365X. (explain)

GeForce GTX 280		48160 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 11160 (30%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 280 is a better choice, by far. (explain)

GeForce GTX 280		19264 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 4464 (30%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at 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 can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
