GeForce GT 430 vs Radeon R9 M380

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M380 should be quite a bit faster than the GeForce GT 430 overall. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M380 will be a lot (more or less 257%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 28800 (257%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M380 is a better choice, and very much so. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 13200 (471%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
