So the specifications are not really current. However, the short look of Threadripper 2990X on Canada Computers made a few other goodies, such as model number (YD299XAZAFWOF), total amount of cache (80 MB) and TDP (250 W). And of course the price, although we are a bit less sure of it than the rest of the information.

The listing is no longer displayed on the dealer's website, but it did not disappear until it was noticed and the screen seized as shown above. The price you see is in Canadian currency; It converts to around $ 1,850 in US dollars. It's almost twice as much as the Threadripper 1950X debuted on ($ 999), but it also has twice the number of physical cores and threads to throw at workload.
All of these cores will pack four 8-core Ryzen door-on packages, associated with AMD's Infinity Fabric. It is also worth noting that the next batch of Threadripper CPUs will maintain compatibility with the TR4 connector so that existing owners should be able to upgrade without replacing their existing motherboards (after a BIOS update, naturally).
