This forum won't even accept that the Intel ARC cards have a hardware bug. You really think they will accept that a company that has been making GPUs for 30 years would release a hardware bug?
It's not something we have run into often. Back with the OG Phenom launch there was certainly a bug that kept the clock speeds capped. They had to respin and relaunched as the Phenom II very shortly after. But that was because AMD was barely competitive without the projected clocks.
Intel, you have the rumors but the proof is in the pudding. No way Intel dedicated so much resource and power for a GPU that performs at the level they do. But its not so much a bug but a design oversight (as reported) and is architecture problem. Which is why reports are that Battle Mage won't fix the issue, its design is basically capped and its replacement would be finished before they would finish with a Battle Mage redesign.
This seems something a respin might correct and for a design that would be in market for 1.5-2 years if there is something they could do to get higher clocks I don't see why AMD wouldn't respin it for a refresh. Considering the power design, the main GPU die size, I don't think AMD ever designed it to be a 4090 opponent. Which makes it seem like they choose the clock for Yields and that above that there would be wild variance. Also AIB's specially the non-strict AMD only AIB's, never put much effort into their AMD designs compared to NVidia (and Intel when talking boards). It's very possible they could be doing something not great with cooling, power phases, and power management. If AMD had a bunch of near launch testing units and cooler designs for more than 2 8 pin connectors, I think there might be some foundation in there being an issue. But the coolers and reference board design look like 350 was always the target mark. AMD didn't drop 12v connector, it wasn't designed for it, they didn't drop a third connector. It very much looks like this was always its design mark. This looks to be there HD 4870 moment. Not the top, but close enough, cheap enough, cheaper to manufacturer, and also not some oversized monstrosity.
