GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which comes with core clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

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

Theoretically speaking, the GeForce GTX 750 should be 213% quicker than the GeForce 9500 GT 1GB GDDR3 in general, due to its higher data rate. (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 quite a bit (more or less 271%) more effective at anisotropic filtering 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

The GeForce GTX 750 should be quite a bit (more or less 271%) 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 losing too much performance. (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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
