GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 750

Intro

Compare those specs to the GeForce GTX 750, which features GPU clock speed of 1020 MHz, and 1024 MB of GDDR5 memory 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 9500 GT 1GB GDDR3		50 Watts
GeForce GTX 750		55 Watts
	Difference: 5 Watts (10%)

Memory Bandwidth

The GeForce GTX 750, in theory, should perform quite a bit faster than the GeForce 9500 GT 1GB GDDR3 overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 54400 (213%)

Texel Rate

The GeForce GTX 750 should be a lot (more or less 271%) faster with regards to AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 23840 (271%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 750 is the winner, and very much so. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 11920 (271%)

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 data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR 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 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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