NewFatMike posted: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? Pitcairn performance would be nice, but even with DDR4 and TBR I don't think they'll get rid of the memory bottleneck entirely.

Why the hell are you even talking about the 1050, leaked specs say it's pretty much a RX460*0.6 and if the arch delivers, we might even see it come close to that and not get choked to poo poo by memory bandwidth.

PC LOAD LETTER posted:Geez if they can just put a "lousy" 1GB of HBM1 on their APU's it'd be a huge win for iGPU performance. It could probably compete fairly well with some of the mid-ish range dGPU's at 1080p or less resolution with that. Seems like that isn't gonna happen though. At least not for 2017. As much as I'd like to see a zen quad with a RX480-level GPU on die paired to a stack of HBM, but it doesn't make any sense for Raven Ridge when and the memory controller can push 30-40 GB/s on DDR4 at average clocks. The GPU part is absolutely tiny. Arzachel fucked around with this message at 12:00 on May 31, 2017 |

NewFatMike posted:Still great for SFF stuff, hopefully the ****HQ or ****HK equivalent models for mobile will be 80-90% of the desktop models combined with Freesync 2 panels. GF's process nodes seem to be way more efficient at low voltage and clocks and I don't think Vega will change that one bit, but raw shader power has never been the issue. DDR4 gets us half way to not choking the iGPU to death but the hype around Vega for me was the TBR/DSBR implementation which seems pretty underwhelming right now. It might be down to the HBM2 memory controller severely underperforming and I'd like to see some testing done on this, but I don't think AMD can properly feed 11CUs at 800 mhz. Edit: now that I've looked at it more, Vega has less effective memory bandwidth than Fiji while still outperforming it by a decent margin  That bodes well for Raven Ridge even if Vega is pretty poo poo.

Amd uses Ryzen the same way Intel uses Core, Ryzen 2 is only used on lovely clickbait techsites.

Paul MaudDib posted:Zen is basically Broadwell-level IPC, which is only a few percent behind Skylake/Kaby Lake/Coffee Lake. Intel's lead is pretty much down to clocks and that largely comes down to GF 14nm being a low-power-optimized process that sucks rear end above 4 GHz. I think it's also down to Summit Ridge being AMD's first shot at both the architecture and the process, the stepping used for Threadripper dies moves the scaling wall 200-300 mhz up.

Twerk from Home posted:I'm skeptical that price differences among sub-$200 CPUs really matter, especially in the desktop space. The rest of the computer, especially RAM, is really drat expensive too. I'm all for more power to more people, but the CPU doesn't really dictate the price of the whole machine. Shaving off 50 bucks CPU might let you go from a 1050ti to 1060 which is a pretty big deal if you're on a tight budget.

I kind of doubt that it's the power draw, people usually aren't too fussed if a desktop CPU pulls a bit more. My guess would be that they're running into the same clockspeed wall again except it's 300mhz higher.

KingEup posted:I have some questions about the AMD Ryzen 5 2400G and because my use case is unusual I can't find much information anywhere else. Prebuilts with Intel's Hades Canyon (i7-8809/8805) are coming out soon-ish and will be a good deal more powerful and significantly more expensive, doesn't seem like the SoC itself will be available seperately any time soon either. I don't think 12nm/7nm AMD APUs have been announced. You're never going to be CPU limited even with a low resolution outside of some extreme corner cases. Dual channel is pretty much mandatory and memory clocks are also a huge deal, I'd aim for at least 3000 with decent timings.

So it seems Pinnacle Ridge isn't limited by the process but maybe through design? It's too bad AMD couldn't have found a way to make the BCLK async, multiplier OC is still better but an async BCLK might have enabled even higher clocks, maybe 4.6 to 4.7Ghz, or a really cold 4.4Ghz. Not sure if it's limited to X470 but boards with external clock gen should have an async mode. The Stilt posted:Pinnacle Ridge CPUs also support multiple reference clock inputs. Motherboards which support the feature will allow "Synchronous" (default) and "Asynchronous" operation. In synchronous-mode the CPU has a single reference clock input, just like Summit Ridge did. In this configuration increasing the BCLK frequency will increase CPU, MEMCLK and PCI-E frequencies.
