GeForce 9500 GT DDR2 vs Radeon R9 M375X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be a lot better than the GeForce 9500 GT DDR2 overall. (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%) more effective at 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 superior to the GeForce 9500 GT DDR2, 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 largest amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
