GeForce GTS 150 vs Radeon R9 M280X

Intro

Compare those specs to the Radeon R9 M280X, which features a core clock speed of 900 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

GeForce GTS 150		32000 MB/sec
	Difference: 56000 (175%)

Texel Rate

The Radeon R9 M280X should be just a bit (about 6%) faster with regards to AF than the GeForce GTS 150. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 3040 (6%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M280X is a better choice, and very much so. (explain)

Radeon R9 M280X		14400 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 2560 (22%)

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 transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels the video card could possibly record 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 the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
