GeForce 9600 GSO 384MB vs Geforce GTX 780

Intro

Compare that to the Geforce GTX 780, which comes with a core clock speed of 863 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2304 SPUs, 192 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 384MB		84 Watts
Geforce GTX 780		250 Watts
	Difference: 166 Watts (198%)

Memory Bandwidth

Performance-wise, the Geforce GTX 780 should in theory be quite a bit superior to the GeForce 9600 GSO 384MB in general. (explain)

Geforce GTX 780		288384 MB/sec
GeForce 9600 GSO 384MB		38400 MB/sec
	Difference: 249984 (651%)

Texel Rate

The Geforce GTX 780 should be a lot (more or less 528%) more effective at anisotropic filtering than the GeForce 9600 GSO 384MB. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce 9600 GSO 384MB		26400 Mtexels/sec
	Difference: 139296 (528%)

Pixel Rate

The Geforce GTX 780 is a lot (more or less 528%) more effective at FSAA than the GeForce 9600 GSO 384MB, and should be able to handle higher resolutions without losing too much performance. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce 9600 GSO 384MB		6600 Mpixels/sec
	Difference: 34824 (528%)

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 max amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
