Try mentioning their names (Ryan, PCPer, etc) into your question/request. I asked about Quadro scores ("Do PCPer have quadro scores?") and they answered immediately. Or maybe I was lucky.I asked if they could run a benchmark that isolates geometry performance, and to try that one program that can show whether a gpu has some kind of tiled rasterization, but they didn't even notice me in the chat.
For thermal issues, it shouldn't do much. Below 85C, there shouldn't be an appreciable error rate or the DRAM is faulty. The error rate ECC is meant to avoid would be spectacularly unlikely in the short demo period even once.Not what it's for, but it can help to a limited degree.
Where was that indicated, and what would that have to do with thermal issues?HBM was having issues with voltage fluctuations from the wide IO, so it could be playing a larger part. Especially if they did away with non-ECC parts.
Basic parity checks would not have the information necessary to fix anything.Didn't mean to imply that level of scrubbing, but just fixing single bit errors transparently as they're detected. Similar to most parity checks.
Is there a specific citation of 4x256 dwords with regards to VGPRs?http://llvm.org/docs/AMDGPUUsage.html
Some interesting tidbits there on GFX9, but still haven't found that line I recall. Closest thing was 4x256 dwords for VGPR allocations. What I recall was a series of resource allocations. It may have been in one of their independent testing branches, so having a difficult time finding it. Maybe that "Register Mapping" WIP section.
But i watch this picture carefully,it‘s no different with my R9 Nano.I watched the live stream. Just tried trianglebin on my 290 (GCN2) and it's completely different to what I saw Vega do. The whole upper triangle flashes weirdly all at once on the 290 whereas Vega flashes and changes in big tiles, then smaller ones as seen in the screenshot taken in the middle of the transition.
Vega is definitely doing things different than good old GCN.
Oh,I see the different.Thank you.
Let's be fair: unless it's based on some feedback from AMD, his comment about that doesn't have more weight than that of any other internet poster.So Ryan's testing confirms all the previous ones, and drivers will not change much, Ryan thinks pretty much 10% max with a new RX driver.

Has anyone yet been able to come up with a logical explanation as to why AMD chose not to provide cards to the press for one of their most important releases of last couple of years, outside of the shamefull PCWorld hands-off preview? I mean, the optics of this are just God-awful, akin to a studio refusing to screen a major movie to the critics which is never a good sign.
