Antrame irgi HD530 - silpnesne HD510, jei G4400

Kiek raso ir kiek realiai yra, tai kartais gerokai skiriasi, tas ypac Celeron'ams galioja.
Uzrasytu jiems 35W be T raides, vietoj tu ~53W tai net nebutu melas. 
Pentium'ui panasu, kad apie 50W realu (G3420 FPU+GPU isspaudziau ~54W)
G3420 CPU dalis 3,2GHz - ~30W.. 1,6GHz - ~10W.. 0,8GHz - ~4-4,5W

Kas del GPU:
https://en.wikipedia.org/wiki/Skylake_(microarchitecture)
Full fixed function HEVC Main/8bit encoding/decoding acceleration. 
Hybrid/Partial HEVC Main10/10bit decoding acceleration. 
JPEG encoding acceleration for resolutions up to 16,000x16,000 pixels. 
Partial VP9 encoding/decoding acceleration.

Senesnieji (Haswell) turi partial HEVC. Tiesa, Celeron'ams ir Pentium'ams tipo ne.

Taciau youtubinius 4K haswell'inis G3420 tempia geriau nei i5-2400.
