GeForce GT 430 1GB vs Radeon R9 M375

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 should be a lot faster than the GeForce GT 430 1GB in general. (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 (more or less 263%) more effective at AF 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 is quite a bit (approximately 480%) more effective at FSAA than the GeForce GT 430 1GB, and also should be able to handle higher resolutions without losing too much performance. (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 max amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling 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 could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few 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.
