GeForce 9500 GT 1GB GDDR3 vs Geforce GTX 690

Intro

Compare all of that to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this particular card. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
Geforce GTX 690		300 Watts
	Difference: 250 Watts (500%)

Memory Bandwidth

In theory, the Geforce GTX 690 is 1402% faster than the GeForce 9500 GT 1GB GDDR3 in general, due to its greater data rate. (explain)

Geforce GTX 690		384512 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 358912 (1402%)

Texel Rate

The Geforce GTX 690 will be much (more or less 2562%) better at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Geforce GTX 690		234240 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 225440 (2562%)

Pixel Rate

The Geforce GTX 690 is quite a bit (approximately 1231%) faster with regards to full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and also will be able to handle higher resolutions without slowing down too much. (explain)

Geforce GTX 690		58560 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 54160 (1231%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, 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 most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
