GeForce 9500 GT DDR2 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which uses a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be a lot superior to the GeForce 9500 GT DDR2 in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M375X will be a lot (more or less 361%) faster with regards to anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375X is the winner, by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9500 GT DDR2		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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 max fill rate.
