Geforce GTX 770 vs Radeon R9 M365X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Geforce GTX 770 will be 212% quicker than the Radeon R9 M365X overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Geforce GTX 770 is much (approximately 262%) faster with regards to AF than the Radeon R9 M365X. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Geforce GTX 770 is a better choice, and very much so. (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 (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
