GeForce GT 430 vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which has a clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X will be 233% faster than the GeForce GT 430 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon R9 M385X should be a lot (more or less 450%) faster with regards to AF 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 lots of anti-aliasing is important to you, then the Radeon R9 M385X is a better choice, by far. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
