GeForce 9500 GT 1GB GDDR3 vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which has GPU core speed of 1515 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2944 SPUs, 184 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
GeForce RTX 2080		215 Watts
	Difference: 165 Watts (330%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 will be 1692% quicker than the GeForce 9500 GT 1GB GDDR3 overall, due to its greater bandwidth. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 433152 (1692%)

Texel Rate

The GeForce RTX 2080 is quite a bit (about 3068%) faster with regards to anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 269960 (3068%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 is the winner, by far. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 92560 (2104%)

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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
