I would assume those prices are just early gouges, we will have to wait to see what prices look like when there is wider availability. Also, we do have a GPU thread for this stuff.

Don Lapre posted:Professional audio equipment. Don't need it. USB 2.0 is fine for any almost any home studio. MADI cards are for people running recording facilities or doing front of house stuff because nobody else needs 100+ channels of physical i/o. You still don't need TB for that either since its been on PCI-E 4x cards for ages. TB adoption is moving ahead nevertheless, probably driven by Macbook Pro users that don't have any ports except TB. There are perhaps latency reasons for the industry to offer TB since interrupts are handled differently (no usb host controller polling etc). If anything they will probably offer USB/TB in tandem like my RME UFX offers USB/Firewire in tandem. When you buy an expensive soundcard, you tend not to replace it every 3 years like everything else connected to your PC. RME UFX+ is USB/TB but it also has MADI built in, so you pay £700 more for it. The more pressing concern in relation to AMD is UAD being poo poo about their non Octo dsp cards because none of them seem to work on AMD boards for some peculiar reason. If you have a UAD Apollo, its TB or bust. WanderingKid fucked around with this message at 11:48 on Aug 12, 2017 |

Is there a rough way of figuring out how many cores you'd use and need? Games have started to support six cores, but say I have something like: * An open browser in the background * OBS streaming * OBS recording Would this mean that OBS takes up one core - or thread - for each task on top of the six cores being utilized, assuming I have the cores to spare, or is the scaling/parallellization different? I'm just wondering how vertical and horizontal something like this is, and how I can try to make sense of how many cores I could need and use ahead of choosing a CPU once I have to weigh Coffee Lake against Ryzen.

Its really not that straight forward. Music production software for instance can theoretically use as many cores as you have. They do this by threading every mixer channel and as long as each channel shares no input/output dependency with any other channel, they can be processed simultaneously. But in real terms, I don't know anyone that keeps all their mixer channels completely independent. You route channels into other channels and into buses. You create parallel channels which all share the same input. Multiple channels share the same signal processing. Because audio production is a real-time process, you also have to beat the playback buffer or your get audible dropouts. For this reason, real-time audio processing is bound by the cpu processing time of all the serial parts of the mixer signal chain. Its textbook Amdahl's Law. On my current FL Studio project, core utilization on an i7 6700K barely tops 30% on the highest core but cpu load is 90% at 48khz with a 1024 sample playback buffer (approximately 22ms latency). This project has just over 40 channels. There are 10 audio sources, so roughly 30 of those channels are parallel channels or mix buses and between those there are many other connections so a channel output can be used to control effects on other channels via envelope followers. It does not have to terminate in a speaker or headphone out (because at a fundamental level, there is no difference between control signal and audio signal except the latter eventually goes to an speaker/headphone output while the former does not). The channel routing is a bit spaghetti-os. To illustrate, Waves TG12345 stereo channel strip is a 10% cpu load hit per instance on my rig. If I stack 8 instances on one channel it results in an 80% cpu load hit because this signal chain is entirely sequential. The 8th instances depends on the 7th for a valid input, the 7th depends on the 6th for a valid input and so on. You can't parallelize this signal chain in real time. The cpu load meter in FL Studio is not about core utilization. It is an estimate of cpu process time. If I double the sampling rate from 48khz to 96khz, I have doubled the number of per sample audio operations per unit time, so the cpu load massively increases even though core utilization does not. However, if you are working with 8 independent channels, with 1x instance of TG12345 on channels 1 to 8 inclusive, then as long as none of these channels share i/o dependency, there is no penalty to cpu process time beyond the first instance. The cpu load will be 10%. If you connect the output of channel 1 to the input of channel 2 however, you have created an i/o dependency between channel 1 and 2 and the cpu load increases to 20%. Off-line render doesn't have strict time requirements to get poo poo done so process time is not critical. You can split the work up easier and divvy it out to multiple cores. Other types of work are defined by large scale concurrency like heavy VM usage. But for the type of thing I'm doing, IPC and clock speed matters. A single core is a prolific multi-tasker and is capable of handling many threads thanks to something called time division multiplexing. This is important for any timing critical workload. Going from an i7 6700K to an R7 1700 you must then acknowledge the following: To benefit from the extra 4 cores/8 threads, you have to take advantage of opportunities to parallelize the work. Opening a project made on an i7 6700K is going to result in higher cpu load because Ryzen IPC and clock speed are lower. However, you have twice as many opportunities to add independent channels with monster effects processing for no effective penalty to cpu process time. To do this, you need to build your project and your mixer signal chain from the ground up to make use of the extra cores. In short, you will change the way you mix. Is this good or bad? Its neither, its just a different way to use the resources you have. WanderingKid fucked around with this message at 15:04 on Aug 12, 2017 |

Most synth based approaches don't depend on lower level cache sizes (it's just code generating stuff), sample based ones not really either, because the samples are usually way larger than the cache.

Actually you are right. Its not right to say opening a project made on an i7 6700K rig on an R1700 rig will result in higher cpu load solely due to lower IPC and clock speed. It really depends on the way the project is structured.

Ran some relevant "benchmarks" for myself, able to do a full rebuild of UE4.17 in 12 minutes, where as it took me 50~ minutes before with a 4 year old i7. That about matches up my workstation that has two 8-core Xeons  Temp is a little higher than expected, sitting at 26c idle with a Arctic Liquid Freezer 240 AIO. Probably just need to reseat it and check if I applied enough TIM I guess?

It's what hit under load that really matters. Seems to be topping out at 60c (reporting from the Ryzen Master software) after running stress on CPU-Z for around 15min. Looking around that seems to be more inline with what I should expect, for some reason I thought I read some article hitting 20c/40c for idle/load.

It should be double the single-thread performance, double the cores, un-bottleneck the SSD, give me GbE (it's a really crappy motherboard. I've got a spare GbE pcie card but the only PCIe slot is blocked by the graphics card) and give me USB3. Plus I'm replacing the 5,400 rpm hard-drive with a 7,200 one. However it won't be quite the end of the road for the CPU. I've also got Linux box running on an AMD Athlon 64 X2. I plan to flash the bios to add AM2+ support and transplant the CPU over. Despite being an even older machine, it's a far nicer motherboard. Pablo Bluth fucked around with this message at 08:43 on Aug 14, 2017 |

Vega reviews are out. Vega 56 looks pretty good compared to the Geforce 1070, but the 1080 can't be beat.  Power draw, lol. Also, Vega 56 launches in two weeks, and it remains to be seen if the market price of the card will match the MSRP of $400. Maxwell Adams fucked around with this message at 14:47 on Aug 14, 2017 |

AMD is just lucky that the mining craze has jacked up prices. MSRP vs MSRP would be a bloodbath. I got my aftermarket 1070 for $350 so that FPS per dollar chart is just hilarious.

Did we confirm that it's going weird CU shutoffs with that, so clocks aren't necessarily representative of total performance? I still very badly want Raven Ridge to be good, but I'm not sure it'll be "console replacement" material in mobile form factors, even with a Freesync 2 panel. Hopefully it will be, but Vega keeps making me sad.

NewFatMike posted:Did we confirm that it's going weird CU shutoffs with that, so clocks aren't necessarily representative of total performance? Performance was in line with the clocks, the card just needs to be undervolted and the power limit raised, this causes the card to run faster while not running into its 300W power limit. I just wish there wasn't such airtight protection on the BIOS, playing with them might see some nice performance gains.

Yeah, there seems to be some fuckery with what CUs are active or not because Buildziod in working with GN found that if you push things just hard enough performance can actually degrade. It's basically doing the same thing Pascal does.

One of the leaked Raven Ridge APUs looked to be roughly an Xbox One graphics config (704 shaders at 800mhz for Raven Ridge vs 768 at 853mhz in Xbone, but an older shader design), but i think that was a desktop part. 15in Macbook Pro's use a 15w CPU + ~30w GPU (thats roughly the same number of shaders even) and has fairly bad thermal throttling, so 45w is probably the outer edge of the window if you want to get into reasonable sized laptops. 45w is normally the TDP of intel's biggest mobile-specific CPUs too.

It's amazing how GN does exactly the things the AMD fanbase wants (there were literally threads on /r/AMD begging for reviews to undervolt Vega) and still gets poo poo on because they didn't crown Ryzen the new Gaming King even though they said it's better for all the other stuff. It's amazing how long people can hold a petty grudge over a single review they disagreed with. GN does a lot of very good work. Like sometimes Buildzoid has more in-depth stuff about overclocking because he's balls-deep in hardware modding and stuff, or TechReport might have slightly easier frametime graphs to digest, or TechPowerUp does better summaries, but GN is like 90% as good as each of the specialties of those sites, and they get more poo poo about being anti-AMD than I do. Super glad to hear Buildzoid is partnering with them. They just need to find a few more nerds with wacky hairstyles and they can start a band.
