despite the common verdict of the Precision 7770, and I agree their performance and design flaws aren’t worth their workstation price premium., but still I ordered one, and didn’t end up returning it. Why? Because on Dell’s Outlet store got one with i9, 64GB RAM, and 16GB A4500 GPU for a relative steal by combining discount codes totaling -81% off, paying $2,100 when sticker price was $9,865!!!!
It has met the needs of my academic research analyzing and training models on large engineering datasets, can even play Forza Horizon 5 at Ultra setting on 3440×1440 widescreen monitor at 60-75 FPS!
The most marketing oriented waste of ressources and money I have seen in recent years. With only 210Watts of AC power available, the mainboard is physically incapable of using CPU and GPU at the same time. Putting this amount of power into components that are half the price will give similar, if not better results. (better because a 4090GPU has a larger baseline powerdraw, and needs to be extra careful to not accidentally fry itself under that flimsy heatsink). This thing is like an 7.2l V8 with a fuelpump capped to 1 Gallon per hour: Overtaking a Big Truck will… Read more »
Can you just upgrade the power supply / wall adapter to 300W+ to get better performance? Also, I understand recent BIOS updates have fixed, or at least mitigated many (all?) of the thermal / amperage management concerns.
