GeForce 8300 GS (OEM) vs Radeon R9 M280X

Intro

Compare all that to the Radeon R9 M280X, which has GPU core speed of 900 MHz, and 4096 MB of GDDR5 memory set to run at 1375 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

GeForce 8300 GS (OEM)		40 Watts
Radeon R9 M280X		75 Watts
	Difference: 35 Watts (88%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M280X should be 1275% quicker than the GeForce 8300 GS (OEM) in general, because of its higher bandwidth. (explain)

Radeon R9 M280X		88000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 81600 (1275%)

Texel Rate

The Radeon R9 M280X will be quite a bit (approximately 2700%) more effective at AF than the GeForce 8300 GS (OEM). (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 48600 (2700%)

Pixel Rate

The Radeon R9 M280X should be a lot (approximately 1500%) more effective at AA than the GeForce 8300 GS (OEM), and also able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M280X		14400 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 13500 (1500%)

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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many 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.
