It's not that surprising that AMD has trouble building a compiler that outperforms LLVM; LLVM has decent code generation, Ryzen's scheduling requirements can't be that different from Core's or they'd suck wind on existing software, and AMD doesn't afaik have a serious compiler team. What's surprising is that they'd build a wet fart of a compiler and then actually release it. Why bother? How do they gain?

So if AMD can only build good architectures when Jim Keller is around, what's their plan for after Zen?

FaustianQ posted:It's two months, I highly doubt drivers aren't "ready" at this point. I was getting drops of drivers with "critical fixes" (including follow-up email to make sure we'd deployed it to all the test/demo machines) 3 weeks before Fiji street date. They also likely locked the demo config a fair while before the demo date. Nobody gets to check in anything meaningful to the demo branch the week before Lisa goes on stage.

FaustianQ posted:So drivers used in demo like this aren't even likely good, rather "stable". Well, they believe they show off the product well enough to put the CEO in front of it, so that tells you something. They're very likely not the drivers that will be available on day 1 of the glorious Vega future. Whether they are now ready, or will be then, or will be ever, is more philosophical than technical.

The other thing is that people infer quality from price. If something is 10% cheaper it's a good deal. If it's 30% cheaper it's a lower-tier product.

Intel needs to be careful to not piss off the customers who've been buying at $2K per. "You could have sold this to me at $750? WTF?" is a tough sales context for future conversations.

Dunno if they're going with AMD's design or what, that's quite a mix of companies. Presumably AMD is doing the iGP.

Paul MaudDib posted:Yeah, ICC is good at extracting performance from Intel chips. But that's real performance that you would have in real-world usage. It's AMD's responsibility to push patches into LLVM or GCC or write their own compiler if they think they're leaving performance on the table. Didn't AMD release a compiler that sucked?

If no part of the OS code is executing, the lights don't change. Sometimes big pieces can be locked, though, and have that portion still function.

The Chromium (really Blink) embedding APIs are much richer than those for Edge, which are basically enough for a help viewer and not an application. There's a reason nobody has done the work to rehost Electron on top of Edge, and it's not because nobody has whined about using 0.2% of the disk. I expect that the Westminster-hosted app will be totally new code, and much less capable. (Like all WinRT ports of popular applications.)

WinRT apps based on HTML/JS have much reduced capability compared to non-RT apps based on Blink. Just as with web-tech apps trying to build on top of Edge.

I remember Intel sending dev support people to my work in the late 90s to tell us to change x<<4 to x*=16 all over our code so it would run faster, because of some architectural change in P4. Ridiculous in several ways, but that's Netburst for you.

Looks like 8700K undercuts on price ($40 CAD cheaper with it at launch pricing), and is only 13% slower on perfectly parallel cinebench while 21% faster on single-threaded. Apparently someone has a 5.2GHz OC on a delidded 8700K, which should be another 20% (minus what Ryzen can get from OC, but that’s not much by my understanding). Maybe that was an early lottery win, I guess. Even if that’s a wash, is the Ryzen honeymoon over? Maybe in mid-spectrum with the 1600X they’re still solid? It’s a much stronger performance from Intel than I expected, tbh. https://www.extremetech.com/gaming/257006-intels-core-i7-8700k-reviewed-six-core-chip-punches-far-weight-class E: actually, looks like the 8700K OC situation might be overstated above.
