GeForce GTS 150 vs Radeon R7 240

Intro

Compare all of that to the Radeon R7 240, which has core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce GTS 150		141 Watts
	Difference: 111 Watts (370%)

Memory Bandwidth

Theoretically speaking, the GeForce GTS 150 should be just a bit faster than the Radeon R7 240 in general. (explain)

GeForce GTS 150		32000 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The GeForce GTS 150 should be a lot (about 224%) more effective at texture filtering than the Radeon R7 240. (explain)

GeForce GTS 150		47360 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 32760 (224%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTS 150 is the winner, by far. (explain)

GeForce GTS 150		11840 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 6000 (103%)

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 MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be 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 this number, the better the card will be at 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 the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
