GeForce 9500 GT 1GB GDDR3 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which has a clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce 9500 GT 1GB GDDR3		50 Watts
Radeon RX 470		120 Watts
	Difference: 70 Watts (140%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 will be 725% faster than the GeForce 9500 GT 1GB GDDR3 overall, because of its greater bandwidth. (explain)

Radeon RX 470		211200 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 185600 (725%)

Texel Rate

The Radeon RX 470 will be a lot (about 1247%) faster with regards to texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 109728 (1247%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 470 is a better choice, by far. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce 9500 GT 1GB 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 largest amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
