GeForce GT 130 vs Radeon R7 M265

Intro

Compare that to the Radeon R7 M265, which uses a 28 nm design. AMD has set the core frequency at 725 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 should be 167% quicker than the GeForce GT 130 overall, 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 quite a bit (more or less 45%) more effective at texture filtering than the GeForce GT 130. (explain)

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

Pixel Rate

The GeForce GT 130 will be much (about 38%) better at full screen anti-aliasing than the Radeon R7 M265, and will be able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
