Went from 3900x to 12700k. Intel is FAR better for various reasons. I am using a DAW studio type computer and Intel is raping AMD in latency out of the box. There are many variables but still, Intel rules the roost for this.

Winifred Madgers posted:Step 1: Give it less volts. To OP wondering about CPU undervolting: it's... kinda tricky. In days of yore, when I was undervolting an AMD FX-8320, it literally involved stepping down the core voltage by small increments and testing until I found a point where it became unstable, then nudging the voltage up slightly, testing again to see if it was stable, and then hopefully calling it a day. This approach may still work on a modern CPU - hop into the BIOS, see where your core voltages lie, and start gently adjusting voltages and seeing what happens. redeyes posted:Went from 3900x to 12700k.

To cleanse the timeline a bit: https://twitter.com/VideoCardz/status/1542026339707981827 https://twitter.com/9550pro/status/1542003665975709696 Was kinda disappointed with those single core scores at first given the big bump in cache (from 44MB to 68MB) and clocks, but CPU-Z doesn't seem to care about L3 much. The 5800X3D scores lower than the straight 5800X in those tests. So whomst know yet!!

From what I've read there doesn't seem to be substantial single-threaded improvement over Alder Lake, with the gains going to multi-threaded as you'd expect from adding more E-cores. Will that change by launch time, or is any single-threaded performance gain just going to come from higher clocks?

# ? Jun 29, 2022 15:03 |

I'm curious about the power considering how much Alder Lake needs to hit the last hundreds of mhz. Maybe they'd at least run the E-cores at appropriate voltage as someone mentioned before.

I think someone here (Paul?) confirmed that the little cores are running on the same 12V line as the big ones. Since the little cores aren’t operating at an efficient voltage, Intel decided to juice the clocks to get what performance they could out of them, and with Raptor Lake they’re literally doubling down on the strategy. In the future - and especially for mobile-targeted chips - I’d expect Intel to adopt BIG.little with appropriate voltages to suit the strengths of each, but that will likely require a socket change to accomplish.

I haven't really read anything exhaustive on how it works yet, just trying to piece together some articles. Still though FIVR is a linear regulator so the more you drop, the more you dissipate. It's better than switching transistors with it, but it's still pulling power and turns it to heat, etc, it's basically a big variable resistor. There is a per-core voltage control mode too... and potentially you could reduce the allowed multiplier on the e-cores to push them a little farther into the efficiency range. But yeah maybe they just are clocking them too high to win benchmarks. Alder lake in particular, the e-cores may not end up being worth it, because as Shamino notes, if you disable the e-cores you you can "yeet the ring multiplier" as he puts it. He's getting 5 GHz, I assume with LN2, and and you can supposedly get to like 42x-44x on ambient. Only 8 e-cores potentially isn't enough to make it worth it - yeah it'll be a bit faster in parallel stuff probably, but games/etc still favor punchy cores over more cores. https://www.anandtech.com/show/17206/the-msi-meg-z690-unify-motherboard-review-ddr5/8 https://www.tomshardware.com/how-to/intel-alder-lake-cpu-overclock-guide https://www.overclock.net/threads/maximus-z690-and-alder-lake-modern-cpus-require-modern-overclocking-solutions.1794893/

I assume the e-cores are much more efficient on mobile processors where the voltage will be saner and the clocks lower?

The "partial FIVR" thing appears to mean that unlike predecessor chip Tiger Lake, where most supply rails including CPU cores were FIVR, in AL only uncore is powered by FIVR. Uncore is Intel speak for things like last level cache, ring bus or mesh interconnect, and so forth. Finally, the voltage supplied from motherboard to FIVR regulators is fixed and relatively high - 1.8V, iirc. This is because, once again, it's not linear.

The multicore performance achieved by alder lake would have been impossible without them, and that was the design objective. Intel could not have made a halo product without them. Yes, they could claim to have the fastest gaming CPU again with just 8+0, but gaming was/is not the only aim.

I think 42x is fairly easy even with all cores on? Not sure about 44x.

Are there any desktop chips coming like the mobile -U chips that have more efficiency cores than performance cores? It's weird to me that most of the desktop lineup has no E-cores, and they're reserved for only the higher end parts at huge TDPs. On the mobile side, I see a whole line-up of things like the the Pentium 8505 and even lower end Celerons packing 5 cores now, and then by the time you're in the mid-range i5s the mobile parts have 10 cores, 2P + 8E. Why aren't we seeing mid or low priced desktop chips with a full host of E cores?

If you have your motherboard's model number on hand, we can help look up your manual and steer you towards the settings. Out of curiosity, what precisely are you trying to accomplish? Are you trying to preserve your processor by taking a little bit of thermal stress off of it? Do you have an overclock in place and you want to take the voltage down a little bit, or do you have running on the stock clock and you just want it cooler regardless? I ask because it is also possible and perhaps more straightforward/stable to underclock the CPU--or even do a blend of the two.

I am reminded from my time in the trenches for a prominent video card and motherboard mfg I had the same weirdo demanded swap out of of an RMA because he was getting instability trying to undervolt the stock yorkfield era cpus because they wanted a cool room. I doubt that's op's need but undervolters are out there.

Qualcomm is up to 4 tiers now Though that's supposedly less to do with power efficiency and more to do with maintaining 32bit support when ARM has mostly dropped it from their reference cores, so they threw in a couple of 32bit cores

That is indeed a good starting place. in addition to that undervolt, you can also drop the clock a few hundred GHz and REALLY save some power Further, you might actually find it necessary to drop the frequency a little bit as you reach lower and lower undervolts: higher frequencies need higher voltages to remain stable--so as you lower the voltage, you may find that you might also need to lower the frequency a bit as well Potato Salad fucked around with this message at 13:49 on Jul 7, 2022 |
