I recall morphling1 did the same thing with his whitewater type block to avoid 3 barb design.

If that's the case, then it reminds me more of Volenti's rotated implementation. morphling1's block still had the "horizontal" path to the fins, but just routed to a "vertically" placed outlet.
Volenti's had a "vertically" oriented set of fins (like in the TDX), but still routed to two outlets, however had he just removed one of the outlets, it would have been the same.
In the case of rectangular dies, the performance of the "White Water" design is linked to the orientation of the CPU die. It's better to "slice" the CPU up into more channels, than it is to have the channels span the length of the die. For the squared Palomino and Intel P4 dies, it doesn't really matter. For the T'Bred B and the Barton cores, there is a small gain to be had by having the orientation shown. For the A64 dies, which are "vertically" aligned, the TDX orientation will actually reduce performance.
All depends on what one is optimising for. The original orientation of the RBX (and the White Water) are more appropriately targetted for next-gen CPU die orientations.
