GeForce 9500 GT DDR2 vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which features a GPU core clock speed of 725 MHz, and 512 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
Radeon HD 6750		86 Watts
	Difference: 36 Watts (72%)

Memory Bandwidth

As far as performance goes, the Radeon HD 6750 should in theory be much superior to the GeForce 9500 GT DDR2 in general. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 will be a lot (approximately 197%) faster with regards to AF than the GeForce 9500 GT DDR2. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 17300 (197%)

Pixel Rate

The Radeon HD 6750 should be quite a bit (more or less 164%) better at AA than the GeForce 9500 GT DDR2, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9500 GT DDR2		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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
