GeForce GT 130 vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which comes with a GPU core clock speed of 725 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 should be 167% faster than the GeForce GT 130 in general, due to its higher data rate. (explain)

Radeon R7 M265		32000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 20000 (167%)

Texel Rate

The Radeon R7 M265 is a lot (about 45%) more effective at AF than the GeForce GT 130. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 5400 (45%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 130 is a better choice, by a large margin. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 2200 (38%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated 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 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 get to the max fill rate.
