GeForce GTS 150 vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which features a core clock speed of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X should be quite a bit faster than the GeForce GTS 150 overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 40000 (125%)

Texel Rate

The GeForce GTS 150 should be quite a bit (approximately 28%) faster with regards to texture filtering than the Radeon R9 M365X. (explain)

GeForce GTS 150		47360 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 10360 (28%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M365X is superior to the GeForce GTS 150, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 2960 (25%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 ability to reach the maximum fill rate.
