GeForce GT 430 vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which has GPU core speed of 1100 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M385X should perform much faster than the GeForce GT 430 in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M385X is quite a bit (about 450%) better at anisotropic filtering than the GeForce GT 430. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 50400 (450%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M385X is superior to the GeForce GT 430, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 14800 (529%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
