10TFlops at full precision? I very much doubt that.

Navi gets up to 8.5 TFlops with 225W, Vega VII up to 11 with 300W TDP. Even just the 225W of the Navi are way too much for a console, that's about the TDP budget of the entire console, CPU, RAM, SSD, etc... included. Did I mention that both are produced in 7nm already?

At half precision, 10 TFlops are entirely possible. And I'm pretty sure the engineers did tell this numbers since Navi gets the same performance as Vega with about 35% less TFlops in raw power, so the increase over Pro/X would look rather low despite a sizable performance boost.

The only way they could make them work at full precision is to make the boxes a lot bigger to allow for larger coolers and fans, otherwise they RRoD themselves in no time. But then also don't expect such lowly prices as $499 for such a console, even by next year that would be too expensive.

You looking at the wrong gpu, look at radeon 5700, not radeon 5700XT

Add some undervolting and you can hit good numbers, around 1,7ghz+ on tsmc 7nm is the magic number and on tsmc N7P or 7nm+ it should be 1,8ghz+. But we are getting indications they going for 2ghz.

I don't know where you getting your TF number from but radeon 5700 is 7,8TF+ and radeon 5700XT 9,5TF+.

Based on numbers I stolen from someone else, a console with 44CU's at 1,8ghz should pull about 195W on tsmc N7P or tsmc 7nm+ and maybe 230W with 44CU's at 2ghz, it will depend on when exactly Navi power consumption goes out of whack on Tsmc N7P or Tsmc 7nm+.

The TFlops you're quoting are at peak boost performance, which the GPU can't hold without consuming much more than those values you're posting below. For instance, in the Techpowerup test the GPU only reached 1672 Mhz on average, which results into almost exactly 7.7 TFlops. Undervolting will simply not be enough to get to 10 TFlops, especially since 160W is already the maximum a console can take. And Navi translates that into more clock speed anyway by itself unless you lock the speed - but that only gives like 30-40 Mhz in general while it would need more like 200-300 Mhz to make it work for your example.

However, I agree that I did mess up a bit, I took consumption at max boost and used the TFlops at base clock. Still, my point stands that 10 TFlops are still out of reach
