Stronger CPU was already considered when Osiris Black leaked the original Neo news on Gaf. Said the upgrade will raise price to $499 potentially.
The bandwith on the GDDR5 ram is 216? GB/s. Its limiting what the GPU can be since you generally want a 2:1 ratio between teraflops and 100 gb/s. They can switch out the GDDR5 for GDDR5x since the memory controller is the same. The peak bandwidth can then be 320gb/s.
The clock on the GPU is probably conservative if its a Polaris part. This is likely the result of going with GDDR5. Clock the GPU higher by 33% to 1.2 ghz, and you'll have 5.6 teraflop part, which goes toe to toe with rumoured Scorpio targets.
In summary.
Better than Jaguar CPU at 2.4 ghz.
1.2 ghz GPU 5.6 teraflops.
8gb of GDDR5x, 280 gb/s.
$499 at launch small loss.
This is all assuming that neo is a more than just a fab shrink to 14nm LPE instead of a 14nm LPP port. If it is LPE then current specs are the max
Edit:
Seems like GDDR5x is not necessary. Peak bandwidth on the 480 is 256 gb/s with GDDR5.
