GeForce 8300 GS (OEM) vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this specific card. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X should be quite a bit faster than the GeForce 8300 GS (OEM) in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 89600 (1400%)

Texel Rate

The Radeon R9 M385X should be quite a bit (more or less 3322%) more effective at texture filtering than the GeForce 8300 GS (OEM). (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 59800 (3322%)

Pixel Rate

The Radeon R9 M385X is much (about 1856%) better at AA than the GeForce 8300 GS (OEM), and also capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M385X		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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
