GeForce 9500 GT 1GB GDDR3 vs GeForce RTX 2080

Intro

Compare those specifications to the GeForce RTX 2080, which comes with core clock speeds of 1515 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 2944 SPUs as well as 184 TAUs and 64 ROPs.

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

Texel Rate

The GeForce RTX 2080 will be much (approximately 3068%) better at 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 using a high screen resolution is important to you, then the GeForce RTX 2080 is superior to the GeForce 9500 GT 1GB GDDR3, and very much so. (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 (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, 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 most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
