GeForce GTS 150 vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which comes with a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTS 150 is 100% quicker than the Radeon R7 M260 in general, due to its greater data rate. (explain)

GeForce GTS 150		32000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 16000 (100%)

Texel Rate

The GeForce GTS 150 should be much (approximately 176%) better at texture filtering than the Radeon R7 M260. (explain)

GeForce GTS 150		47360 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 30200 (176%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTS 150 is a better choice, by far. (explain)

GeForce GTS 150		11840 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 6120 (107%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
