GeForce GTS 150 vs Radeon R7 260X

Intro

Compare those specifications to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory works at a speed of 1625 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 260X		115 Watts
GeForce GTS 150		141 Watts
	Difference: 26 Watts (23%)

Memory Bandwidth

The Radeon R7 260X should in theory perform much faster than the GeForce GTS 150 in general. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 72000 (225%)

Texel Rate

The Radeon R7 260X is quite a bit (about 30%) more effective at anisotropic filtering than the GeForce GTS 150. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 14240 (30%)

Pixel Rate

The Radeon R7 260X should be a lot (more or less 49%) faster with regards to anti-aliasing than the GeForce GTS 150, and should be able to handle higher resolutions while still performing well. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 5760 (49%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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