You also said New Mac Pro in November
I also said the holdup was Vega. Vega was delayed and didn't ship in November. I can't control the weather, or the ship date of Vega.
and that the nMP would have swappable video cards.
I said the 2013 nMP would
likely get GPU upgrades.
On what I've said: If Apple releases another Mac Pro, you're the one who looks wrong. I feel pretty good about that. Vega is appearing in macOS drivers. The Mac Pro is the only Mac that makes sense for Vega. At this point, I look pretty good.
I've been saying that Vega was the holdup for a while, and that Apple was likely the one pushing it's development. Suddenly last week you have another blog saying that Vega was going to show up in a new Mac Pro as one of the first platforms. So far I seem to know what I'm talking about way more than you do.
I don't have any direct knowledge that Apple was the one pushing for faster Vega development, but after Polaris going so badly, I wouldn't be surprised if that's what happened.
I'll also still stand by November being the timeframe Apple was aiming for.
Radeon 480 would have around 60% more TFLOPS than the D700.
The 480 is basically a budget card. It is better than the D700, but it gets beaten by the 1070 and 1080. The 480 also doesn't meet the thermal requirements for the Mac Pro, which means more down clocking. As I've said elsewhere, if Apple released a Mac Pro with Polaris on the high end, nobody would buy it anyway and there would be another around of complaining.
It still seems to me that AMD promised Apple that Vega would ship closer to Polaris, it isn't, and everything is slipping. That's the perils of Apple going with a single GPU vendor.
Most of what's going on here is without Nvidia as a vendor, Apple is chained to AMD's release schedules and products.
