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 clocked the core speed at 925 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Radeon R9 M365X		37000 Mtexels/sec
	Difference: 96888 (262%)

Pixel Rate

The Geforce GTX 770 will be quite a bit (approximately 126%) faster with regards to AA 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 max amount of information (in units of megabytes 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 speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
