GeForce 9500 GT 1GB GDDR3 vs Radeon HD 6750

Intro

Compare all that to the Radeon HD 6750, which comes with GPU core speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
Radeon HD 6750		86 Watts
	Difference: 36 Watts (72%)

Memory Bandwidth

In theory, the Radeon HD 6750 should perform a lot faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 38400 (150%)

Texel Rate

The Radeon HD 6750 will be quite a bit (approximately 197%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 17300 (197%)

Pixel Rate

The Radeon HD 6750 will be much (approximately 164%) faster with regards to anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 7200 (164%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
