Yeah, it seems a bit of an unsung hero that what used to be a $400 upgrade + $350 BTO option (the Vega 20) is now the new low-end GPU, and at a better process at that.
Good point. Though the Vega 20’s non-availability on the entry level 15” MBP is best ascribed to Apple’s market segmentation strategy, it’s perfectly valid to observe that the GPU performance available now at $2,400 on the 16” was previously only offered at $3,150+ on the 15”. The migration down-market is welcome, and it’s a legit $350 value, just as the 256GB—>512GB SSD bump saves $200 on the 16”.
Of course the Apple-hate crowd will downplay this and say it’s to be expected, since technology gets more powerful and cheaper over time. ¯\_(ツ)_/¯
But compared to the 15” model being sold just a few days ago, it’s fair to say the specs for the $2,400 entry level 16” model are equivalent to a $2,950 15”. The new model also has the added benefits of the larger battery; a larger, higher density, higher resolution display; (reportedly) noticeably improved speakers/mics; and not insignificantly, the keyboard improvements.
(It’s also worth noting that a side benefit of the updated GPUs is support for two Apple 32” XDR displays at 6016 x 3384 @ 60Hz. Note also the new refresh rates available in the internal display in addition to 60Hz: 47.95Hz, 48.00Hz, 50.00Hz and 59.94Hz.)
All in all, it’s hard (for me, anyway) to see this as anything other than a solid update and at least a 25% better value for the entry level model, though not strictly a $550 discount over the 15” equivalent config.
(Not sure what happened to HBM, though. Did AMD abandon it? Or is that a high-end thing Apple is no longer interested in?)
GDDR6 offers similar performance to HBM2 in this case, though it requires more power and a larger die area than would HBM2 (both issues are largely offset with the move from GloFo’s 14nm to TSMC’s 7nm process). Also, since it doesn’t require an expensive interposer, GDDR6 is not as expensive to implement.
I’m reasonably sure AMD is forgoing HBM2 across the board with Navi. It’s an AMD design decision, separate from Apple. AMD can get the performance it needs without having to use the more expensive HBM2, and no doubt Apple is on board with the resulting cost savings.
