GeForce 9600 GT 1GB vs Radeon R7 250X 2GB

Intro

Compare that to the Radeon R7 250X 2GB, which has GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon R7 250X 2GB should theoretically be much superior to the GeForce 9600 GT 1GB in general. (explain)

Radeon R7 250X 2GB		72000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R7 250X 2GB is a lot (approximately 92%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 19200 (92%)

Pixel Rate

The Radeon R7 250X 2GB will be a lot (more or less 54%) more effective at FSAA than the GeForce 9600 GT 1GB, and will be capable of handling higher resolutions more effectively. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 5600 (54%)

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 max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
