GeForce 9500 GT DDR2 vs GeForce GTX 960

Intro

Compare those specifications to the GeForce GTX 960, which features GPU core speed of 1127 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also features 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 960		120 Watts
	Difference: 70 Watts (140%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 960 should in theory be a lot superior to the GeForce 9500 GT DDR2 in general. (explain)

GeForce GTX 960		112000 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 96000 (600%)

Texel Rate

The GeForce GTX 960 should be quite a bit (about 720%) more effective at AF than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 63328 (720%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960 is superior to the GeForce 9500 GT DDR2, by far. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 31664 (720%)

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 data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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