Eh, so long the console generations don't last like 10 years again and PC gaming is the victim again by things being held back due to multiplatform poo poo. I mean, on the CPU front, things like IPC improvements have been slowing down for a while now, still current quadcores beat the consoles silly, and trend is going towards more than four cores, via Ryzen and also Intel's Coffee Lake. On the GPU side, dies are getting bigger and bigger and continue bring significant improvements due to easy parallelization.

If Raven Ridge can deliver 1080p60+Freesync at medium settings for current AAA titles, I'll be happy as a clam. Medium now is a lot nicer than it used to be, and that'll probably be really good for getting more folks on PC. What would that run, like $300 with a monitor and an HDD? Destiny 2 as a demo, I really want to get my friends on PC for it because it'll support 21:9, but everyone wants to play it on the PS4 they already have. It makes me sad.

eames posted:If Destiny 2 is any indication then consoles are becoming CPU bottlenecked which would explain why the game is locked to 30 fps at any resolution (correct me if I'm wrong). The Scorpio project has a major increase in GPU compute units as well as their speed, unlike the Ps4 Pro that mainly upclocked the CPU/GPU and precisely doubled the GPU compute units.

Yes, that's what I wrote. Destiny 2 info from the devs suggests that GPU focused improvements don't cut it anymore. PS4 Pro has eight Jaguar cores at 2.1 Ghz, Scorpio will have eight Jaguar cores at ~2.3 Ghz. The closest benchmark result for a console Jaguar CPU I could find is this: http://cpu.userbenchmark.com/Compare/AMD-Ryzen-5-1400-vs-AMD-Athlon-5350-APU-R3/3922vsm10020 The lowly quadcore Ryzen 5 1400 is roughly three times as fast single threaded and twice as fast in multithreaded applications compared to the octocore console CPUs (the Athlon 5350 is a 2.1 Ghz quadcore and I'm assuming perfect 2x scaling for this example). You can compare multicore results to an overclocked 1800X if you need a laugh. it is 5x the performance of console CPUs Console CPUs are terrible but it didn't matter until they lifted the GPU bottleneck with this useless VR-driven "almost-4K" mid-cycle refresh, as SwissArmyDruid mentioned. eames fucked around with this message at 19:05 on May 21, 2017 |

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"

Interesting. If the frequencies shown there is what the CPU ran at, instead of nominal while they were actually turboing, bumping the Whitehaven to 4GHz would mean near perfect linear scaling. Which seems doubtful, unless they've improved the interconnect speeds. Which means that the 8C's handicap makes the difference for the scaling to appear linear. So anyway, are there any significant teething issues with Ryzen, that haven't been fixed yet with BIOS updates?

One mainstream problem, and one fringe problem: The mainstream: Memory timings continue to be an issue. Because of how the chip architecture is, Ryzen responds very well to higher-clocked RAM. However, as time as gone on, AMD has released firmware updates to the motherboard manufacturers that have improved them over time. There is a major AGESA update expected by the end of this month that will greatly improve memory compatibility. For best results, though, you are generally still looking at memory that uses Samsung B-die, and only two of the largest sticks that you can find. The fringe: IOMMU groupings are not set up correctly for GPU passthrough to VMs. This is correctable with an ACS patch for Linux. Here's hoping it's correctable by software or firmware and doesn't require a hardware fix. If none of that made any sense to you, don't worry about it. =P But this may be how AMD does their market differentiation between the mainstream and HEDT parts, we just don't know yet. But having that 1800X 8C/16T part got people excited about having a machine well-suited to this application, even if the actual number of available PCIe lanes was just barely enough to allow this. I, for one, am hoping to move to Linux full-time, with a Windows VM running on top of it to service those last few things that need Windows and I don't have a choice for.

Epic suck. Well, AMD are under super-hyper-mega-ultra-crunch time to get ready for Computex. On a scale of increasing amounts of suckitude, here's hoping: * Their priorities are being consumed by having to get the new poo poo ready for when Computex begins on the 30th of May * they can figure out what's wrong * they don't have to hardware rev to fix things * that these issues stem from how AMD intends to segment between mainstream and HEDT.

I did the GPU passthrough stuff a while ago. Worked just fine. However I refused to run the Linux desktop on a secondary poo poo GPU, so I ran either Xorg or Windows on my fat GPU (games and all). Given all the sing and dance, I might as well just have dual booted.

Ryzen is apparently related to the cat cores or at least began it's design stages as "make cat cores better". I'm still flummoxed on why the Scorpio went with Jaguar, and not Puma+ or even the rumored Basilisk if they were going have an issue with Zen cores. It's not even like Zen would be particularly throttled in performance here, they could easily do 8 cores at 2.5Ghz or 4 cores at 3.0Ghz and still be inside the overclocked Jaguar core thermal envelope, Zens just that much better of a design.

The hardware had to be finalized either the end of last year or beginning of this year, in order to ramp up production of the actual hardware and have working devkits available for the game developers. An architecture that isn't out yet certainly wouldn't work, and Puma/Puma+ simply might not have been judged a worthwhile change compared to the option Microsoft actually took, of customizing Jaguar cores further.

If it ain't Raven Ridge, I literally do not loving care. Furthermore, Dell seems to have hit the price/performance apex with the Dell 7000 Gaming this year. For $1000 USD, I get a Kaby Lake i5 + 1050Ti + 1080p IPS display and that will last until the next console hardware generation. Whatever Asus is showing, it needs to be at least that performance level on a APU, and it needs to be interesting, or cheaper, or whatever.

Think we'd be able to get 1050 performance out of an APU? RX 560 is having a tough time getting there, but if AMD can supplant their lowest level graphics cards with APUs, then the Polaris refresh makes a little more sense.

The 1050 / 1050 Ti are really efficient GPUs and still have a 75W TDP. I don't see integrated graphics keeping up with nVidia's current-generation high efficiency GPU when they have at most 50W to play with for the GPU-part alone, and that's being generous.

Even if the DDR4 is using 1.35v for DOCP, that will still be ~0.15 less than GDDR5 (which is typically >1.5v right?). Does that result in a direct translation to ~10% less overall power usage? That by itself would take you from 75W to 67.5W, I don't see 50W as being an unreasonable target. Can't remember if anyone mentioned this but: http://ryzen.online is really nice. Just pick which board you have, and it will email you a notification when they push new files. I used a unique address when I signed up, and have not received any other spam/messages yet either, which is sadly a pleasant surprise. Unfortunately it's only for ASUS and GIGABYTE, but still very nice. ASUS has been going nuts updating all of their QVL lists, I'm assuming this is in preparation for AGESA 1.0.0.6 and the new memory dividers? A few companies have already pushed out beta updates that only have the incoming new memory dividers up to 4000mhz, early forum posts seem promising. It's not clear if the new AGESA is also present, but if it is, they forgot to update the version string. The last time this happened we had official/stable releases the next day.

Besides time constraints as fishmech said, there's lots more up-front money for the design costs there, especially if there's anything semi-custom in the Jaguar cores (it wouldn't be at all surprising to have some DRM features added to a console). GPU seems sufficiently abstracted in the current consoles that it's just a drop-in replacement. Plus, more CPU is harder for game devs to take advantage of in ways that are 100% compatible with the old console. They don't want games having different feature sets on the different models. So a scorpio with a better CPU would kinda only use it to do 60FPS on a title which would otherwise be CPU-limited to 30 despite the new GPU. Nice, but not worth the cost.

Been thinking about what I said, and I think that in the end, i5 + 1050 ti in a Raven Ridge APU is way too high a bar. Maybe with Zen2 + Navi, but right now, no. I still maintain that the Dell 7000 Gaming series is _the_ place to be as far as a gaming laptop is concerned, with that perfect intersection of size, power, screen, and battery life, where if you bumped any one of the component parts any larger, the rest of the system would hold it back? And I do not think that AMD can hit that with a single chip. The best that AMD can do with Raven Ridge, I think, is if you were to plot the above system on a radar chart, and then an AMD APU-based system plotted on top of it, the APU-based system should occupy the same profile, but proportionally smaller, and commensurately cheaper, down around the $750-$800 retail mark.
