Lovely head?
ALM was meant to battle RDNA 2. Came out 6 months before RDNA 3. Sort of.
BMG was meant to battle RDNA 3, if it came out today, it would be less than 6 months before RDNA 4.
It's ACM, not ALM.
2x performance and perf/watt along with many minor fixes existing in Alchemist will make it a far better product. Chips and Cheese article convinces me that lot of the seeming driver related problems will either be significantly mitigated or make it easier to fix by drivers with the new hardware. Previous Intel GPU problems thought to be driver related turned out to be hardware after all.
-Imbalanced architecture
-Idle power management issue
-ReBar performance and compatibility hit
Just think of ReBar. They are aiming Alchemist at "cheap systems", yet is viable in only relatively newer ones. I could stick my RX 480 in my Core 2 system no problem. How silly is that? The A380 is a mere $170 CDN, yet I need to go buy a motherboard, CPU, and new RAM to make it work properly.
Idle power isn't that big of an issue, but certainly there are imbalances in the architecture, hence horrible performance in some games, and even things like why it doesn't perform well in lower resolutions.
Even in die and power use it'll be far more competitive.
Alchemist:
-400mm2 N6 die performing like Samsung 8N 270mm2
-No comparison for power use. Turing generation equivalent at best.
To
Battlemage -
-400mm N4 die performing like 300mm2 N4 from Nvidia.
-Huge power efficiency gains. This is the generation where Ashraf Eassa said were aiming for "leadership perf/watt". With the delays it may not be #1, but may be in the ballpark.
