Dufam ze budu lepsie pamatove kontrolery ako su teraz.

Moving on, we spied a new-generation DDR5 RDIMM by SK Hynix. Designed for next-generation enterprise platforms such as Intel "Sapphire Rapids," the RDIMM ticks at DDR5-4800 MHz, offering 64 GB of density. Sticking with DRAM, we spotted SK Hynix' latest LPDDR4X and prototype LPDDR5 memory solutions designed to power the next-generation of 5G smartphones and ultraportable computers. A smartphone with their fastest production LPDDR4X solution and UFS 3.0 storage was used to offer a public live image processing demo in which camera viewfinder fields from the phone's front camera were generating four high-quality filter previews on-the-fly (something that requires immense processing power and storage bandwidth). LPDDR4X is already pushing data-rates north of 4,667 MT/s DDR, and LPDDR5 will push it even further, with frequencies starting at 5,500 MT/s, at a lower power envelope than LPDDR4X.

ta ramka ma pravdepodobne power filtering a v strede asi cip riadiaci napajanie
Edit tie ramky maju zrejme mensie cipy vdaka lepsej nm technologii tak sa tam hore vojde aj nejaky ten premium filtering pre vacsiu stabilitu. Hoci na ramkach ci v cpu alebo gpu som videl zvacsa 2-3 fazy ne jak cpu 16 fazi co maju niektore top dosky, takze tam asi stacit aj menej.
BTW K latenciam na amd slide som videl ze narozdiel (uz neviem coho asi Threadripper) maju IF a cipy jadier blizsie pri sebe, tak je pravdepodobne mensia inteferencia ked to ma kratsiu drahu. Ale zaujima ma moze to hodit nejaku nanosekundu navyse? Elektrika sice ide svetelnou rychlostou ale aj slnku trva 7 minut kym pride k zemi, nanosekunda to je 1000 (mili) 1000 000 (mikro) 1000 000 000 (nano).

Paměti DDR5 začnou na frekvenci 4800 MHz, kapacita modulů bude i 12 a 24 GB https://www.cnews.cz/pameti-ddr5-zacnou ... 2-a-24-gb/

2x8GB bude zachvilu malo... 2x16GB je zbytocny overkill... takze podla mna 2x12GB bude akurat, za mna fajn, kupil by som 2x12GB

[BiFino]

Presne ako hovoris a aj cenovo to bude prijatelnejsie ako platit zbytocne za 32GB. Takze moj dalsi upgrade bude teda v roku 2021. Rozmyslal som, ze prejdem z 3700x na 4000 ryzen, ale to uz rovno pockam na DDR5 teraz uz len cakam na 3080 Ti.

Cize quad alebo hexa channel x24gb sticky

Tu o 12GB nie je rec.
