GeForce 9500 GT 512MB GDDR3 vs Radeon R9 M395X

Intro

Compare all of that to the Radeon R9 M395X, which comes with clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Radeon R9 M395X		125 Watts
	Difference: 75 Watts (150%)

Memory Bandwidth

Performance-wise, the Radeon R9 M395X should in theory be quite a bit superior to the GeForce 9500 GT 512MB GDDR3 overall. (explain)

Radeon R9 M395X		160000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 134400 (525%)

Texel Rate

The Radeon R9 M395X should be a lot (more or less 952%) better at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 83744 (952%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M395X is superior to the GeForce 9500 GT 512MB GDDR3, and very much so. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 18736 (426%)

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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
