GeForce 8300 GS (OEM) vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 38200 (2122%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M380 is the winner, and very much so. (explain)

Radeon R9 M380		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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
