GeForce 8300 GS (OEM) vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which features a clock frequency of 1020 MHz and a GDDR5 memory speed of 1350 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 750 Ti		60 Watts
	Difference: 20 Watts (50%)

Memory Bandwidth

In theory, the GeForce GTX 750 Ti should be 1250% quicker than the GeForce 8300 GS (OEM) overall, because of its greater data rate. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 80000 (1250%)

Texel Rate

The GeForce GTX 750 Ti is quite a bit (about 2167%) faster with regards to AF than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 39000 (2167%)

Pixel Rate

The GeForce GTX 750 Ti should be a lot (more or less 1713%) faster with regards to full screen anti-aliasing than the GeForce 8300 GS (OEM), and also able to handle higher screen resolutions better. (explain)

GeForce GTX 750 Ti		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: Bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
