GeForce 8300 GS (OEM) vs Radeon R7 260X

Intro

Compare that to the Radeon R7 260X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM runs at a speed of 1625 MHz on this card. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Radeon R7 260X		115 Watts
	Difference: 75 Watts (188%)

Memory Bandwidth

In theory, the Radeon R7 260X will be 1525% faster than the GeForce 8300 GS (OEM) overall, because of its higher data rate. (explain)

Radeon R7 260X		104000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 97600 (1525%)

Texel Rate

The Radeon R7 260X is much (more or less 3322%) better at AF than the GeForce 8300 GS (OEM). (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 59800 (3322%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 260X is a better choice, by far. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 16700 (1856%)

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 (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
