GeForce 9600 GSO 384MB vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which comes with a GPU core clock speed of 1020 MHz, and 1024 MB of GDDR5 RAM set to run at 1250 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce 9600 GSO 384MB		84 Watts
	Difference: 29 Watts (53%)

Memory Bandwidth

In theory, the GeForce GTX 750 should be 108% quicker than the GeForce 9600 GSO 384MB overall, due to its greater data rate. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 9600 GSO 384MB		38400 MB/sec
	Difference: 41600 (108%)

Texel Rate

The GeForce GTX 750 is a lot (approximately 24%) faster with regards to anisotropic filtering than the GeForce 9600 GSO 384MB. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 9600 GSO 384MB		26400 Mtexels/sec
	Difference: 6240 (24%)

Pixel Rate

The GeForce GTX 750 should be much (more or less 147%) more effective at FSAA than the GeForce 9600 GSO 384MB, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 9600 GSO 384MB		6600 Mpixels/sec
	Difference: 9720 (147%)

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 information (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
