GeForce 9500 GT 512MB GDDR3 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The DDR3 RAM runs at a frequency of 1100 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M375 should perform a lot faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 9600 (38%)

Texel Rate

The Radeon R9 M375 is a lot (more or less 361%) more effective at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

The Radeon R9 M375 is much (more or less 269%) better at FSAA than the GeForce 9500 GT 512MB GDDR3, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		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 information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
