GeForce 8300 GS (OEM) vs Radeon R7 240

Intro

Compare those specifications to the Radeon R7 240, which makes use of a 28 nm design. AMD has clocked the core frequency at 730 MHz. The DDR3 memory runs at a speed of 900 MHz on this specific card. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce 8300 GS (OEM)		40 Watts
	Difference: 10 Watts (33%)

Memory Bandwidth

The Radeon R7 240 should in theory be much faster than the GeForce 8300 GS (OEM) overall. (explain)

Radeon R7 240		28800 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 22400 (350%)

Texel Rate

The Radeon R7 240 should be quite a bit (about 711%) more effective at texture filtering than the GeForce 8300 GS (OEM). (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 12800 (711%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 240 is the winner, and very much so. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 4940 (549%)

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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This number 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
