Radeon RX 470 4GB		120 Watts
	Difference: 70 Watts (140%)

Memory Bandwidth

In theory, the Radeon RX 470 4GB is 725% quicker than the GeForce 9500 GT 512MB GDDR3 in general, because of its higher bandwidth. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 185600 (725%)

Texel Rate

The Radeon RX 470 4GB will be much (more or less 1247%) faster with regards to AF than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 109728 (1247%)

Pixel Rate

The Radeon RX 470 4GB is quite a bit (more or less 573%) better at anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 25232 (573%)

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 max amount of information (measured in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at 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 the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
