Are Jaguar cores based on bulldozer? Everyone thinks that consoles have "8" cores, but if they're actually terrible CMT cores then a quad core ryzen would an upgrade. But I'm sure most people would be confused about why the core count "downgraded"

Paul MaudDib posted:Subtracting performance from Intel's benchmark results is bullshit which completely invalidates all of those results. And just to be clear, they are cutting the performance of the Intel chips almost in half. That's an immense level of bullshit right there. And if they really want an apples-to-apples comparison they could run all the benchmarks with gcc and use those numbers. Arbitrarily cutting numbers is so hilariously bad that I can't believe even the worst marketing idiot would expect it to fly.

you can read this for some information from back then: http://techreport.com/review/21813/amd-fx-8150-bulldozer-processor here's a paragraph from the conclusion: Scott Wasson posted:Faced with such results, AMD likes to talk about how Bulldozer is a "forward-looking" architecture aimed at "tomorrow's workloads" that will benefit greatly from future compiler and OS optimizations. That is, I am sure, to some degree true. Yet when I hear those words, I can't help but get flashbacks to the days of the Pentium 4, when Intel said almost the exact same things—right up until it gave up on the architecture and went back the P6. I'm not suggesting AMD will need to make such a massive course correction, but I am not easily sold on CPUs that don't run today's existing code well, especially the nicely multithreaded and optimized code in a test suite like ours. The reality on most user desktops is likely to be much harsher. scott was right

Risky Bisquick posted:The current AM4 CPU and B350 board will work, this does not mean new cpus will necessarily work without a different board/chipset. See Intel. AMD is historically pretty good about this though, and I believe they've said AM4 will be supported through 2020. Bigger question is whether there will be any CPUs that actually warrant an upgrade in that time.

Oh I have no doubts that it will be good, but will it be good enough that if you spent $200 or $300 Ryzen today, that you would then get your money's worth out of another $200 or $300 Zen 2 chip?

EoRaptor posted:Compilers have gotten better (In fact, a lot better, LLVM was/is a major advance in compiler design), however it turns out what itanium needed from a compiler was perfect knowledge of all possible operations an application could perform and all the CPU states that would result, which even with very simple code seems to be an NP hard problem. Also, compilers are still written by humans and aren't capable of the level of 'perfection' needed to even approach what itanium demanded. I agree with what you're saying about itanium but I'm curious why you say LLVM is a major advance in compiler design. To my knowledge its backend isn't as good as GCC or (some) commerical compilers

Paul MaudDib posted:Yes, streamers are typically better off using GPU encoding. CPU encoding has better quality but it's difficult to achieve this in real-time, and if you are going to attempt to do so then the gold standard is to do the encoding on a dedicated machine since anything that exceeds the quality of GPU encoding is also going to poo poo up your framerate something fierce, even on an 8-core processor. Seems hard, you'd need a dedicated machine that can really rip through several threads at once

Paul MaudDib posted:It's not really about price, it's about wasting slots and x16 lanes and screwing up your airflow for something that can be integrated onboard via the PCH. Tons of slots+lanes is one of the big selling points of X399 and you're screwing that up right off the bat. Minor differences in cost don't matter all that much on a $1300 build - even if you could buy a 10 GbE NIC for $50 today, I'd rather drop the extra $50 on the motherboard and have it integrated. The fact that the Zenith Extreme is more expensive than the Fatal1ty is the final nail in the coffin IMO. But then I'd have a motherboard named "Fatal1ty"

PerrineClostermann posted:....Modern overclocking is a risk? I thought it was just clever marketing for higher clocked chips. "Oh, you're totally pushing it to the edge! You're the one bringing the chip to its maximum potential! Isn't that amazing and worth 100 dollars?" The real trick is that it allows chip manufacturers to benefit from performance numbers that they don't actually have to support. Pretty much all coffee lake CPUs should make it to an all-core 5 GHz... But if they don't, it's not Intel's problem

If AMD isn't able to get clocks much higher in the next couple years because of process problems, I wonder if they should go all in on the slower but wider idea. Add more execution units to each core and put in 4-way SMT instead of 2-way. I know IBM made some Power chips that do that, and I think there's an ARM server chip that also has 4-way SMT.... it could potentially be an easy way to get a lot better in some server workloads.

No that's exactly my point. The display sucks more and more power but the battery can only be so big, so it's the CPU and other electronics that need to get more efficient. E: in other words, making your silicon more power efficient isn't something you do to make battery life go up, it's something you do to make it stay the same or go down less

Sony even ended up in several class action lawsuits over it for the following years, one of which resulted in payouts to most people who had bought PS3s before the cancellation of "other os" functionality and could prove they had done so. Did they say why?
