GeForce GT 430 (OEM) vs Radeon R9 390X 8G

Intro

Compare all that to the Radeon R9 390X 8G, which comes with a GPU core clock speed of 1050 MHz, and 8192 MB of GDDR5 memory running at 1500 MHz through a 512-bit bus. It also features 2816 Stream Processors, 176 Texture Address Units, and 64 Raster Operation Units.

In theory, the Radeon R9 390X 8G should be 1233% faster than the GeForce GT 430 (OEM) overall, because of its higher data rate. (explain)

Radeon R9 390X 8G		384000 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 355200 (1233%)

Texel Rate

The Radeon R9 390X 8G will be quite a bit (approximately 1550%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

Radeon R9 390X 8G		184800 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 173600 (1550%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 390X 8G is superior to the GeForce GT 430 (OEM), and very much so. (explain)

Radeon R9 390X 8G		67200 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 64400 (2300%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
