Comparison with other DapE structures in the PDB demonstrates the flexibility of the interdomain connections of this protein. We demonstrated inhibition of DapE by sulfate (IC 50 = 13.8 ± 2.8 mM). This structure contains two bound sulfate ions in the active site that mimic the binding of the terminal carboxylates of the N-succinyl-l,l-diaminopimelic acid (l,l-SDAP) substrate. The 5800X3D must have really high internal thermal resistance.We report the atomic-resolution (1.3 Å) X-ray crystal structure of an open conformation of the dapE-encoded N-succinyl-l,l-diaminopimelic acid desuccinylase (DapE, EC 3.5.1.18) from Neisseria meningitidis.
Seems strange to require a 240mm with maxed out fans to keep temperatures below 90C. I've cooled parts with a lot more power consumption with less heatsink without any problems.
It's usually not a good idea to run those on CPUs, when you can offload them to literally hundreds of small cores on a video card. There exists a small subset of algorithms called 'embarassingly parallel', where locking is minimal and adding more cores results in nearly a linear performance increase, but those algorithms usually run best on GPUs anyway. Eventually, locking overhead means that adding more cores produces negative performance the extra locking eats up more performance than the new cores add. This also adds a great deal of complexity to developing those algorithms, meaning they're often buggier. The more cores you add to nearly all algorithms, the less additional benefit accrues, because of the amount of locking that has to be done. The return on multi-core performance improvement peaks at just 2 processors. If you're not bound on something else (like I/O), single-core performance helps. Every algorithm benefits from single-core performance. In an environment where the poster already has a 3800X, paying more for what is effectively a weaker processor is stupid.īut very few workloads that matter are actually single-threaded. Lastly, the "great majority of users" probably aren't doing things that are CPU-intensive, and wouldn't notice the difference between the 56X, all other things being equal. Lightly multi-threaded workloads like games aren't necessarily going to perform better on the 5600, because it's a much lower TDP part than the 3800X, and clock speed will start to fall off under load compared to the 3800X, reducing or even nullifying the 5600's potential IPC advantage. The 5600 may perform better on a strictly single-threaded workload (I'm taking your word for it for the sake of argument), but very few workloads that matter are actually single-threaded.
ZEN BOUND 2 STARTING AT WEIRD RESOLUTION CODE
Widely multithreaded code is rare, but per-core performance benefits every CPU-constrained algorithm. The 5600 has 15-20%ish better per-core performance, so even with fewer cores, it's a better choice for the great majority of users. The 3800X can get more total work done per time unit, but very few home users actually use computers for processing bulk data. You're mistaking throughput for performance.
ZEN BOUND 2 STARTING AT WEIRD RESOLUTION UPGRADE
I struggle to think of any situation where a 5600 would be an upgrade over a 3800X, nevermind one worth paying any amount of money for. In any case, a 3800X is still an excellent-performing CPU for practically any desktop use case, and while there are certainly better-performing desktop CPUs available today, a 5600 isn't one of them. So yeah, don't bother with a 5800X3D without an AIO of some sort. The only option you have is disabling turbo entirely. What's annoying about all this is that AMD has motherboard makers disabling all the frequency/thermal controls. Perhaps R23 is more intensive than the Blender test that GN does. The max power consumption hit 125W, but the all-core frequency fluctuated between 41, regardless of cooler. Held it down to around 82-84C with the fans and pump maxed out. Cinebench R23 can run its normal 15min without hitting 90C. Same issue, cooler wasn't all that warm.įinally, I dug out a 240mm AIO, a Corsair H100i. Lasted a little longer than the Dark Rock TF, but not much more (maybe 5min) before hitting 90C. The cooler, however, was fairly cool to the touch. It held out a little better, but 90C was hit after a couple minutes. Dark Rock TF, a "220W TDP" cooler from be quiet! also didn't work. That's fair, it's only rated for non-turbo operation on their website. I tested with Cinebench R23 multi-threaded It's possible I did it to prevent Gigabyte from overclocking the CPU, but either way, it was at 3.4Ghz and no faster.
So it turns out my 5800X3D was stuck at 3.4Ghz because the BIOS somehow disabled turbo. Air cooling with the 5800X3D is a fool's errand.
