A Russian website told me this:
The modern system of chemical signs was proposed at the beginning of the 19th century. The Swedish chemist Jøns Jakob Berzelius. The scientist proposed to designate chemical elements with the initial letter of their Latin name. At that time, all scientific articles were published in Latin, it was generally accepted and understood by all scientists. For example, the chemical element oxygen (in Latin oxygenium) was given the name O. And the chemical element hydrogen (hydrogenium) - H. If the names of several elements began with the same letter, then the second or one of the following letters from the name was given in the symbol of the element. For example, mercury (hydrargyrum) is called Hg. Please note that the first letter of the sign of a chemical element is always an uppercase letter, if there is a second letter, then it is a lowercase letter. It is necessary to remember not only the names of the elements and their symbols, but also the pronunciation, i.e. how these signs are read. There are no fixed rules for pronunciation of signs of chemical elements. They must be learned by heart.
From Hg it can be deduced that the letters are pronounced one by one.
also interesting:
Ti this comes from earlier, at that time it was so that e.g. cards with ending mx = mainstream were and cards with ending ti = high end, so is also a nostalgic thought behind it I think.
it started with the first ti, this was the geforce 2 ti vx (ti vx = mainstream/high end), a bit stronger was the geforce 2 ti (ti = high end), because the vx variant of the ti came up with 225mhz/1800mts and the ti (non vx) with 250mhz/2000mts (2001), the geforce 2 ultra was the spice of the nvidia grakas for gamers at the time around 2001.
the whole thing continued until the geforce 4 (4200 - 4800) ti, the mx was the mainstream (mx 420 - mx 4000).
today it is so, that first the ti`s go out (so the chips = gpu), which then differ from the non ti variants (so a bit the worse, or trimmed chips so to say) in about the shader cluster, stream processors, texture units etc. differ.
