Nejprve p\u0159ipome\u0148me, \u017ee grafick\u00fd procesor Turing TU106 je nejmen\u0161\u00ed a nejkompaktn\u011bj\u0161\u00ed \u010dip NVIDIA se speci\u00e1ln\u00edmi RT j\u00e1dry pro ray tracing a tensorov\u00fdmi j\u00e1dry pro urychlen\u00ed funkc\u00ed um\u011bl\u00e9 inteligence. Na druh\u00e9 stran\u011b p\u0159\u00edbuzn\u00fd grafick\u00fd procesor Turing TU116 nem\u00e1 tyto speci\u00e1ln\u00ed v\u00fdpo\u010detn\u00ed bloky, a proto bylo rozhodnuto je srovn\u00e1vat pr\u00e1v\u011b s nimi.<\/p>\n

Grafick\u00e9 procesory NVIDIA Turing se d\u011bl\u00ed na bloky TPC, kter\u00e9 zahrnuj\u00ed p\u00e1r streamovac\u00edch multiprocesor\u016f (Streaming Multiprocessors), v nich\u017e se nach\u00e1zej\u00ed v\u0161echna v\u00fdpo\u010detn\u00ed j\u00e1dra. A jak se uk\u00e1zalo, plocha bloku TPC grafick\u00e9ho procesoru Turing TU106 je pouze o 1,95 mm\u00b2 v\u011bt\u0161\u00ed ne\u017e u Turing TU116, tedy o 22 %. Z t\u00e9to plochy p\u0159ipad\u00e1 1,25 mm\u00b2 na tenzorn\u00ed j\u00e1dra a pouze 0,7 mm\u00b2 \u2013 na RT-j\u00e1dra.<\/p>\n

To znamen\u00e1, \u017ee bez nov\u00fdch tenzorn\u00edch a RT-jader by vlajkov\u00fd grafick\u00fd procesor Turing TU102, kter\u00fd tvo\u0159\u00ed z\u00e1klad GeForce RTX 2080 Ti, zab\u00edral m\u00edsto 754 mm\u00b2, ale 684 mm\u00b2 (36 TPC). Na druhou stranu Turing TU104, kter\u00fd je z\u00e1kladem GeForce RTX 2080, by mohl zab\u00edrat 498 mm\u00b2 m\u00edsto 545 mm\u00b2 (24 TPC). Jak je vid\u011bt, i bez tenzorn\u00edch a RT-jader by star\u0161\u00ed grafick\u00e9 procesory Turing byly docela velk\u00e9 \u010dipy. O dost v\u011bt\u0161\u00ed ne\u017e grafick\u00e9 procesory Pascal.<\/p>\n

A co tedy zp\u016fsobilo tak velk\u00e9 rozm\u011bry? P\u0159edev\u0161\u00edm u grafick\u00fdch procesor\u016f Turing byla zv\u00fd\u0161ena velikost cache pam\u011bti.

Ta m\u00e1 naopak o 25 % v\u00edce CUDA jader, p\u0159i\u010dem\u017e zab\u00edr\u00e1 plochu 314 mm\u00b2 oproti 410 mm\u00b2 u nov\u00e9ho TU106. <\/p>\n
