GeForce 9800 GTX+ vs Radeon R9 M395X

Intro

Compare all of that to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M395X		125 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 20 Watts (16%)

Memory Bandwidth

The Radeon R9 M395X should in theory be a lot faster than the GeForce 9800 GTX+ in general. (explain)

Radeon R9 M395X		160000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 89600 (127%)

Texel Rate

The Radeon R9 M395X should be a lot (approximately 96%) more effective at anisotropic filtering than the GeForce 9800 GTX+. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce 9800 GTX+		47232 Mtexels/sec
	Difference: 45312 (96%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M395X is a better choice, and very much so. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 11328 (96%)

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 information (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the potential to reach the max fill rate.
