GeForce 9500 GT DDR2 vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which features a core clock speed of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 560		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 should perform much faster than the GeForce 9500 GT DDR2 in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 112128 (701%)

Texel Rate

The GeForce GTX 560 should be a lot (more or less 415%) faster with regards to AF than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 36560 (415%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 is a better choice, and very much so. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 21520 (489%)

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 (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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