GeForce GT 430 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which uses a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 RAM runs at a frequency of 1100 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375 should in theory be a lot faster than the GeForce GT 430 in general. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 will be quite a bit (more or less 263%) better at anisotropic filtering than the GeForce GT 430. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 29400 (263%)

Pixel Rate

The Radeon R9 M375 will be much (approximately 480%) better at anti-aliasing than the GeForce GT 430, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 13440 (480%)

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 past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
