GeForce 8300 GS (OEM) vs GeForce GT 320

Intro

Compare those specifications to the GeForce GT 320, which has core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GT 320		43 Watts
	Difference: 3 Watts (8%)

Memory Bandwidth

Theoretically, the GeForce GT 320 should perform much faster than the GeForce 8300 GS (OEM) overall. (explain)

GeForce GT 320		25280 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 18880 (295%)

Texel Rate

The GeForce GT 320 is quite a bit (about 620%) more effective at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GT 320		12960 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 11160 (620%)

Pixel Rate

The GeForce GT 320 should be much (approximately 380%) more effective at anti-aliasing than the GeForce 8300 GS (OEM), and also will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GT 320		4320 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 3420 (380%)

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 data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
