GeForce GT 340 1GB vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has GPU clock speed of 1015 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should in theory perform quite a bit faster than the GeForce GT 340 1GB in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R9 M375X will be much (more or less 131%) more effective at texture filtering than the GeForce GT 340 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 23000 (131%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375X is superior to the GeForce GT 340 1GB, by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 11840 (269%)

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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
