GeForce GT 430 1GB vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this particular model. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M385X should in theory be quite a bit better than the GeForce GT 430 1GB in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M385X should be quite a bit (approximately 450%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 50400 (450%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M385X is superior to the GeForce GT 430 1GB, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 430 1GB		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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a 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. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
