GeForce 8300 GS (OEM) vs Radeon R9 M265X

Intro

Compare all of that to the Radeon R9 M265X, which has clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M265X should perform quite a bit faster than the GeForce 8300 GS (OEM) overall. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 65600 (1025%)

Texel Rate

The Radeon R9 M265X is much (approximately 1178%) better at AF than the GeForce 8300 GS (OEM). (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 21200 (1178%)

Pixel Rate

The Radeon R9 M265X will be a lot (more or less 922%) better at AA than the GeForce 8300 GS (OEM), and capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 8300 (922%)

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 (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher 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 most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
