Thanks for the Radeon VII review. I enjoyed reading it!
The review mentions once or twice that Radeon VII is late to the party and its performance isn't stellar. A day late and a dollar short. I have to give AMD props for launching within a half a year of the 2080 compared to Vega 64 which launched 15 months later. My opinion of Vega 64 might have better a little better if it wasn't launched so far out.
Judging Radeon VII by its power consumption and thermal performance, it looks like its Vega 64 on steroids. This card pushes its power delivery and cooling systems to their absolute limits and beyond. I'm really happy that it competes closely with the RTX 2080 but I was hoping for some additional head room over Vega 64.
It feels like AMD didn't know who it wanted to market to despite claiming that this a high end gaming graphics card. Gamers don't need 16GB of HBM2. Gamers don't need improved FP64 performance. I like these features but it puts the focus all over the place. Radeon VII has its hand in several different pies but doesn't excel at any of those pies (remind me to rework that statement later).
Several people have mentioned this so far and I want to reiterate:
AMD could have reduced the clock speed of Radeon VII and cut its HBM2 reserves in half and marketed this as a RTX 2070 killer. We would have seen easier to manage thermals and a lower price. This Radeon VI (see what I did there?) would have been more appealing to a wider audience.
can't understand the 331mm2 die size on readon vii while rtx 2080 have 545mm2 , amd could smash Nvidia by making bigger cards. why u doing this to yourself AMD? WHY?WHY
The performance : power consumption ratio of Radeon VII is MAXED out right now.
AMD can't extract anything else from this design despite the smaller foot print.
Worlds first 7nm gaming GPU... that consumes 66% more power than the competitor's slightly-higher-performing 12nm GPU. Is it a reflection of AMD's architecture, TSMC's process, or a little of both?
That's a difficult call to make. The difference is compounded by Radeon VII being very inefficient and Turing being very well optimized. Radeon VII is built on the GCN architecture. Its antiquated despite all of the tweaks its received over the years. That's why AMD's Navi architecture is so important: it breaks away from GCN and represents a clean (and hopefully more efficient) slate.
No matter how much a gunsmith tweaks a muzzle loading musket design, it will never be as good as a semi automatic rifle.
