GeForce GT 430 1GB vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which features a clock speed of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 is 22% quicker than the GeForce GT 430 1GB in general, due to its greater data rate. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 should be a lot (approximately 263%) better at texture filtering than the GeForce GT 430 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 29400 (263%)

Pixel Rate

The Radeon R9 M375 will be a lot (more or less 480%) better at FSAA than the GeForce GT 430 1GB, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 430 1GB		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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number 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 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 that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
