RTX 3080 review compilation
Posted: Thu Sep 17, 2020 4:03 pm
Early look: a step and a half to two steps up from RTX 2080, but at the cost of additional power. Some of the aftermarket cards are pushing the core voltage/ power limit a tad harder than others. more to come.
In brief: 2160p performance 35% faster than RTX 2080Ti. 320W TDP, but OEM stock OC'ed cards WILL use more at stress loads. PCIe 4.0, but just a hair faster than 3.0 in benchmarks..probably don't need to run out and get a PCIe 4 mobo for this one. Finally have HDMI 2.1 along with Display Port 1.4a. Supports dual link DVI-D but not analog. May have the new 12-pin PCIe Graphics power connector - OEM cards may have more. Dimensions stated as: a" x b" x c" are from mfgr websites - others are from reviews. No SLI support.
Crash to Desktop issue: Some cards are experiencing failures in the field. Analysis points to capacitor filter designs not handling the high frequency filtering required at the highest boost frequencies causing the system to crash to the desktop. Here's an update from mfgrs via Techpowerup..
9/30/20 update: Nvidia released a driver update to improve stability (w/o saying how they did it - one plausible explanation is the boost clocks freq changes were slowed down so bypass caps could cope). MSI and Gigabyte's statements on it.
