GeForce GT 130 vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which has a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 is 700% faster than the GeForce GT 130 overall, due to its higher data rate. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 84000 (700%)

Texel Rate

The Radeon R9 M380 will be much (about 233%) more effective at texture filtering than the GeForce GT 130. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 28000 (233%)

Pixel Rate

The Radeon R9 M380 is quite a bit (about 100%) better at AA than the GeForce GT 130, and also should be capable of handling higher resolutions better. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 8000 (100%)

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 max amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
