  1. If you're going 12th or 13th generation i9... or the 7950x, forget air-cooling and rackmount cases. No way it can dissipate enough heat (especially under heavy load). Big case and 420mm water-cooler is absolutely necessary. I've been tweaking this 7950x prototype build for a couple days (fine-tuning performance vs noise). I've got it super quiet... but even with the best 420mm water-cooler that exists, idle temps are ~50 degrees C. Cinebench multi-core tests at 38,909. Pretty cool to be able to run amp-sim plugins at sub 1ms total round-trip latency. Probably won't need my portable heater in the studio this winter. 😁
  2. The new 7950x has slightly higher TDP than the 12900ks. It's a tweaker's machine. Performance is outstanding... but getting noise reined-in is complex.
  3. Doing some test Captures with IKMM's Tonex... using 7950x based machine with RTX-3070 video card: Using Default training, Capture process takes ~3 minutes. Using Advanced training, Capture process takes ~20 minutes.
  4. The UMC Interfaces are excellent low-latency performers. During lock-down, lots of folks using them for virtual jams/rehearsals...
  5. The Orion Studio Synergy Core was connected via Thunderbolt. FWIW, No audio interface can achieve round-trip latency that low via USB-2/3. USB-2/3 can achieve ~4ms (under ideal circumstances)
  6. 7950x early low-latency audio performance: In short, impressive. Studio One Pro v5.5.2 with Antelope Orion Studio Synergy Core Able to run Helix Native (substantial patch) at less than 1ms total round-trip latency (96k using a 24-sample ASIO buffer size) Able to run Tonex at ~0.5ms total round-trip latency (96k using a 16-sample ASIO buffer size) Completely glitch-free... (tested playing for hours)
  7. One thing that's currently a bit of a drag is that you can only have a single Tonex "capture" loaded (standalone or in Amplitube 5.5). IOW, You can't have a capture of a tube-screamer... going into a capture of a JCM-800. The current workaround is to use multiple instances of Tonex or Amplitude. I certainly hope IK addresses this. I haven't yet tried the capture process. I'm a bit surprised to hear folks talking about 40-60 minutes for the training process to finish. I've done a fair bit of capturing via the Quad Cortex. It's training process takes a couple of minutes. Even that can be a bit tedious... especially if you're capturing multiple mics/positions. With an hour between "takes", you'll want to plan ahead (test recordings) to make sure you've got it right.
  8. That's the only "solution"... Even then, low-latency performance (by comparison) is pretty lame. 😁
  9. The 7950x will run at 95 degrees C. Note that with proper cooling, it will not thermal-throttle under load. I'd consider quality 360mm water-cooler a minimum. It is a bit alarming compared to previous designs/thermals. 5950x also runs "hot"... but with proper cooling won't thermal-throttle. The 12900ks runs well with quality 280mm water-cooler. I'd expect the 13900ks/s to need a quality 360mm water-cooler (or better). With 16+ core "workstation" type CPUs, air-cooling (even the Noctua D15) just isn't up to the task. 10980xe with D15 with thermal-throttle under significant load. I've tested/verified. There are folks on YouTube who've built Threadripper based machines using the D15. Runs fine at idle and under light loads... Guaranteed to thermal-throttle under significant load (defeats the whole purpose) I've done many prototype Threadripper builds trying to get noise under control. With 280w TDP and active-cooled chipsets... forget it
  10. 12900ks (5.5GHz Max Turbo) TDP = 150w I'll get Max Turbo TDP for the 7950x (once it's fully built/optimized)
  11. 13900k Base Clock: Performance Cores = 3GHz Efficient Cores = 2.2GHz 13900k Max Turbo: Performance Cores = 5.8GHz Efficient Cores = 4.3GHz 7950x Base Clock = 4.5GHz (across all 16 cores) 7950x Max Turbo = 5.7GHz (this is the X-Factor) ie: If the 7950x can achieve Max Turbo across 8+ cores, that's going to be hard to beat.
  12. I'm aware of the 13900k (been running both a 12900k and 12900ks for a good while). 13900k adds eight more efficient cores... and increases clock-speed to 5.8GHz for performance cores... and 4.3GHz for efficient cores. Both the 13900k and 7950x have 32 processing threads. On paper, one would expect the 13900k to leapfrog the 7950x (as 12900k leapfrogged the 5950x)... but it's speculation until we can run audio specific tests. I would have liked to see 8 additional performance cores... instead of 8 additional efficient cores. With the 7950x, AMD seems to have achieved significantly higher all-core clock-speed (vs the 5950x). That kind of leaves the door open to doubt... as the 7950x has 16 full-performance cores... with max turbo of 5.7GHz. The PC Mag article mention's price being ~$100 less than the 7950x. That's not likely... because the current 12900ks is $700 (same cost as the 7950x). Synthetic benchmarks show the 7950x besting the 12900ks in most scenarios. I'm most interested in the absolute limits of ultra low latency audio performance. In that regard, there's not a huge difference between the 5950x, 12900k, and 12900ks. Audio specifics to come...
  13. AMD's Ryzen 7xxx series has been released. Base: 4.5Ghz Turbo: 5.7GHz 16 cores 32 processing threads TDP is listed at 170w Absolutely needs robust cooling (95 degrees C) You can get it to run quiet... but it's definitely more complex than something like a 12700k. Audio specific details to follow. Want to see numbers compared to M1 Max? 😁
  14. One night, we had a sound engineer "sound-checking" guitar for 45 minutes. Want to guess what instrument the sound engineer plays? 🎸 Annoyed us... and certainly annoyed the patrons! Another night, we had a (last minute fill-in) "house" sound engineer who mixed the entire show while sitting at the bar (back to us the entire night). Clearly didn't want to be there... Talked with the venue owner (great guy)... and that particular fella won't be mixing any more of our shows. Yet another show, we had a young lady running sound... who spent more time texting her boyfriend than actually mixing the band. Local festival where we had to load-in five hours early... because they shut down roads Made for a long night We're easy to work with... and we like the same in the sound engineer. Someone competent... with decent gear... who's mixing (problem solving) the entire show At this point, there's a handful of local sound engineers that we'll use. If we can't get one of those folks, we won't book the gig. With three band members 50+, life's too short for carp sound. 😁
