I first saw this elsewhere and was struggling to get my head around it a bit. What I think I'm seeing is:
Zen 3+, Refresh of Zen 3 for DDR5 support as well as other smaller improvements
Zen 4, much bigger update, will be further out. I also wonder if this implies they will focus on the more profitable server space with Zen 4 first, and consumers will get it later with Zen 3+ holding the fort for longer.
Be very careful about the IPC numbers thrown around. It is worth considering two IPC values: architecture, and platform. I suspect Zen 3+ will have a low architecture IPC improvement, but may have a bigger platform IPC increase from DDR5 for example.
For the server chips and Zen 4, I think the platform improvements will enable bigger practical performance increases than architecture alone.
You want a 4K monitor but Ultrawide as well? Dell decided to share a bit of its CES 2021 in advance by announcing its new UltraSharp Monitor.
The new monitor is the first 40inch 4K Ultrawide monitor (which Dell markets as 5K) on the market.
Named the Dell Ultrasharp U4021QW, it features a resolution of 5,120 x 2,160 (140ppi), curved (2500r), it offers 90W charger via USB Type-C and Thunderbolt 3.
Panel type is what you would expect from Ultrasharp series, an IPS. If it would be my guess, probably manufactured by LG.
It also features dual 9-watt speakers. And it covers 98% of the DCI-P3 color gamut and 100% of the Adobe sRGB spectrum.
Noticed something interesting with the ports?
It is also a mini dock with Ethernet
2x HDMI 2.0 ports
Thunderbolt 3 port (with up to 90 watts of charging as mentioned) / USB-C downstream port for charging
4x USB-A ports (all are 3.2, where 3x Gen 2 and 1 Gen 1 with charging)
RJ45 Ethernet jack (No info on speed, probably 1Gpbs)
3.5mm plug for audio.
Dell says that it will arrive on January 28th, 2021 for $2,100 US

SSD or Solid State Drive is a storage device containing non-volatile flash memory, used in place of hard drive because of its much greater speed. Unlike a hard drive, a solid state drive doesnt have any moving parts. It has two main components - A flash controller and NAND flash memory chips.
More information on solid state drives can be had from here..
This guide differentiates SSDs in different tiers based on their DWPD, sustained writes, controllers, NAND types and value for money.
