GeForce GTX Titan vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which has a GPU core clock speed of 925 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX Titan should in theory be quite a bit better than the Radeon R9 M365X in general. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 216384 (301%)

Texel Rate

The GeForce GTX Titan will be a lot (approximately 407%) faster with regards to AF than the Radeon R9 M365X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 150488 (407%)

Pixel Rate

The GeForce GTX Titan will be much (more or less 171%) more effective at FSAA than the Radeon R9 M365X, and also will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 25376 (171%)

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 data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 are processed per second. This figure is worked out by multiplying the total amount of 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 maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
