Geforce GTX 770 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 RAM is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Geforce GTX 770 should in theory be much better than the Radeon R9 M365X overall. (explain)

Geforce GTX 770		224384 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 152384 (212%)

Texel Rate

The Geforce GTX 770 should be quite a bit (more or less 262%) better at texture filtering than the Radeon R9 M365X. (explain)

Geforce GTX 770		133888 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 96888 (262%)

Pixel Rate

The Geforce GTX 770 should be a lot (more or less 126%) better at full screen anti-aliasing than the Radeon R9 M365X, and capable of handling higher screen resolutions without slowing down too much. (explain)

Geforce GTX 770		33472 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 18672 (126%)

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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
