GeForce 8300 GS (OEM) vs GeForce GTX 750

Intro

Compare that to the GeForce GTX 750, which features core speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 750		55 Watts
	Difference: 15 Watts (38%)

Memory Bandwidth

Performance-wise, the GeForce GTX 750 should in theory be quite a bit better than the GeForce 8300 GS (OEM) overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 73600 (1150%)

Texel Rate

The GeForce GTX 750 should be much (approximately 1713%) better at AF than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 30840 (1713%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 750 is the winner, and very much so. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 15420 (1713%)

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 information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
