GeForce 9800 GTX+ vs Radeon R7 250X

Intro

Compare those specifications to the Radeon R7 250X, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM runs at a frequency 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

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 50 Watts (53%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X should be a little bit faster than the GeForce 9800 GTX+ overall. (explain)

Radeon R7 250X		72000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX+ will be a small bit (about 18%) more effective at texture filtering than the Radeon R7 250X. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 7232 (18%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 250X is a better choice, and very much so. (explain)

Radeon R7 250X		16000 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 4192 (36%)

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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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