GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 970

Intro

Compare all of that to the GeForce GTX 970, which makes use of a 28 nm design. nVidia has clocked the core speed at 1050 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular card. It features 1664 SPUs as well as 104 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
GeForce GTX 970		145 Watts
	Difference: 95 Watts (190%)

Memory Bandwidth

Performance-wise, the GeForce GTX 970 should in theory be quite a bit superior to the GeForce 9500 GT 1GB GDDR3 overall. (explain)

GeForce GTX 970		224000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 198400 (775%)

Texel Rate

The GeForce GTX 970 will be much (more or less 1141%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 100400 (1141%)

Pixel Rate

The GeForce GTX 970 will be much (more or less 1427%) more effective at full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 62800 (1427%)

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 information (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. 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 better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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