GeForce 9500 GT 1GB GDDR3 vs GeForce RTX 2080

Intro

Compare those specifications to the GeForce RTX 2080, which comes with a core clock speed of 1515 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It features 2944 SPUs, 184 Texture Address Units, and 64 ROPs.

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

In theory, the GeForce RTX 2080 is 1692% faster than the GeForce 9500 GT 1GB GDDR3 overall, because of its higher data rate. (explain)

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

Texel Rate

The GeForce RTX 2080 should be quite a bit (more or less 3068%) faster with regards to texture 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 a high resolution is important to you, then the GeForce RTX 2080 is the winner, by a large margin. (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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
