GeForce 8800 GTS (G92) vs GeForce GTX 650 Ti 2GB

Intro

Compare that to the GeForce GTX 650 Ti 2GB, which uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory runs at a frequency of 1350 MHz on this specific card. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 25 Watts (23%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 650 Ti 2GB should in theory be quite a bit superior to the GeForce 8800 GTS (G92) overall. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 24320 (39%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be a lot (more or less 43%) more effective at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 17792 (43%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 650 Ti 2GB is superior to the GeForce 8800 GTS (G92), and very much so. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 4448 (43%)

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 largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics 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 amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
