GeForce 8300 GS (OEM) vs Radeon R7 250X

Intro

Compare that to the Radeon R7 250X, which comes with a core clock speed of 1000 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Texel Rate

The Radeon R7 250X will be quite a bit (about 2122%) better at AF than the GeForce 8300 GS (OEM). (explain)

Radeon R7 250X		40000 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 38200 (2122%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250X is superior to the GeForce 8300 GS (OEM), by far. (explain)

Radeon R7 250X		16000 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 15100 (1678%)

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 (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
