What are the different tiers of technology?

All the technology upgrades I’ve found have a suffix which seems to determine the tier or effectiveness, such as “Tau” or “Sigma”. How many of these tiers are there and which is the strongest?

  • Is No Man's Sky actually multiplayer?
  • Is there an easier/quicker way to fully explore a planet for 100% completion?
  • Can I start over in No Man's Sky?
  • Is there a bonus for scanning an entire planet?
  • How does upgrade adjacency work?
  • How do I make Units efficiently?
  • Can I start over in No Man's Sky?
  • Steam No Man's Sky on Mac?
  • Finding the rare element Omegon
  • What are these slowly pulsing white dots on my scanner?
  • Is there a bonus for scanning an entire planet?
  • What makes sentinels hostile?

    There are four tiers of tech upgrades: Sigma, Tau, Theta and Omega. Their comparative strengths rank as follows:

    Omega > Theta > Tau > Sigma

    The stronger the upgrade, the rarer/more expensive the materials required to build it will be, as noted by @David Yell.

    As noted by user @SGR, not every tech has four tiers — four is the maximum you’ll see, and the comparative ranks shown above still apply to techs with fewer tiers of upgrades.
