Title: Lenovo ThinkPad T490s using the same motherboard as smaller X390 may explain feature loss
Post by: Redaktion on March 20, 2019, 19:29:31
As the release of Lenovo's newest business laptops of the well known ThinkPad brand comes closer, we discovered an interesting fact in the support documentation of the ThinkPad T490s and the smaller ThinkPad X390: Both use the same mainboard design.

Well, I already decided that the T490s is not an option for me anymore, because I need dedicated graphics. It would be interesting to see how different the thermal throttling will be between the T490s and X390, but I expect both will do worse because of the thinner design than the previous generation. Let's see if the T490s can still sustain 700 points in Cinebench R15 with an equivalent i5 CPU.

I'm waiting for the T495 (AMD alternative)  but if it's going to have soldered ram and things like that, I might just pass thinkpads in general, I don't know what do they to offer anymore, they're just copying the worst things from apple, throttling, soldered ram (maybe ssd some day?), not to mention their awful prices outside US. (well, in the US they're still overpriced IMO)

I doubt it can. It's now using the X280-style single heatpipe, and the X280 couldn't even sustain turbo long enough for one run at 700 with the i5, steadily dropping down to 530 sustained.
(I cannot link it, but search for "X280 notebookcheck" to see the actual test results).

That being said, early PSREF snooping is promising. Looks like Lenovo will finally be installing decent FHD displays in most of their higher end thinkpads (at least the upgrade options are decent, at first glance). Near 1000:1 contrast, 300+ nits, and ~100% claimed sRGB (or as Lenovo archaically calls it: 72% NTSC). Far better than the current crop of junk (X1 Carbon and Extreme excluded).
