GeForce 8300 GS (OEM) vs GeForce GTX 650 Ti

Intro

Compare all that to the GeForce GTX 650 Ti, which features core speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

	Difference: 80000 (1250%)

Texel Rate

The GeForce GTX 650 Ti will be a lot (more or less 3200%) better at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 57592 (3200%)

Pixel Rate

The GeForce GTX 650 Ti is much (approximately 1550%) faster with regards to FSAA than the GeForce 8300 GS (OEM), and also should be able to handle higher resolutions better. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 13948 (1550%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
