It just seems so incredibly sloppy to not have that be consistent. Do they expect all of their readers to then audit the code of the benchmarking that they are doing to ensure that it cannot possibly be bound by this?

There is no need to start out every article with remedial lessons. It is reasonable for an enthusiast magazine to assume familiarity with how computers work. The average ExtremeTech reader should already know what memory is and how increasing the amount of memory changes (or doesn't change) performance. It is not possible to give all the systems the same memory configuration. They don't support the same memory and do…

I feel sad just reading this reply has to be spelled out so clearly on HN. The standard practice that has been the case since before the Internet.

They had to give the Eypc 4 more RAM to populate all its RAM channels. I've read it has 12 channels of DDR5.

I believe it is just 8

LOL Both are correct. Threadripper Pro has 8 Channel, and Threadripper only has 4 ( damn ). And op was correct in saying EPYC, which really do have 12 memory channel, but obviously he is wrong when it is Threadripper and not EPYC.

For me as a developer it does not bother so much that some tasks like compilation or rendering or AI-training can take a long time. What bothers me is that I am doing multiple things at the same time like say committing to git or rebasing and trying to read my code at the same time, taking backups simultaneously. So this would seem like an ideal, if not overkill processor for me.

Has anyone done a perf / watt scatterplot of the current AMD and Apple offerings? I'd guess this wins in absolute performance (due to the TDP), but I've heard AMD is pretty competitive on energy efficiency too these days. I'm typing this on an M2, which is simultaneously cooler and faster than my old Intel laptop. Wondering if it's time to upgrade my decade-old Intel Linux desktop to an AMD yet.

> I'd guess this wins in absolute performance No need to guess: An M2 Ultra will get around 27,000 in Cinebench R23 while this Threadripper will get around 100,000. The M2 Ultra has a TDP around 90 watts (~ish according to a couple reviews) and this Threadripper has a TDP of 350 watts.

There's some more nuance to efficiency than just max power at max load, of course. The Apple chips will likely have good efficiency compared to the lower core count (say, 32) TR because the watts per core gets high on those smaller TR chips. Yet if you compared their performance at a fixed 90w, I suspect the threadripper would come out ahead, since chips are much more efficient when at fractional loads that don't lead to boosted core clocks. Then again, at idle, the TR is probably guzzling power relative to the M2 Ultra. I'm only speculating to illustrate; a thorough comparison of their perf/watt characteristics would involve sampling many types of workloads of varying thread counts and levels of per-core saturation.

Can't wait for Linus Tech Tips to do some great benchmarks on this thing!

Is this a joke? Isn't their whole thing pretty much lacking rigor in everything they do? Why would you want benchmarks from them?

Actually, no - their thing for the past few years has been to build out the most comprehensive test bench across all PC hardware components. "LTT Labs." They are aiming to become the authority on hardware performance and reliability, and have invested heavily in the tools and industry experts required to do that. Linus doesn't do any testing himself; he is just bankrolling it with the proceeds from his main channel and other media properties.

I find this whole thing super fascinating, coming from the perspective of Silicon Valley startups.

I am just wondering if it would be better and cheaper to buy an Threadripper 7980X 64 Core for Server than EPYC. You get higher single core performance. Specifically for those workload where bandwidth isn't an issue.

Something like StackExchange [1] could fit all their 9 server into 1 ( or 2 with one for redundancy ) without any degraded performance.

These chips have 8 channel ram, so you need at least 8 sticks to get full ram bandwidth.

Aren't there 16GB DDR5 sticks? With smaller sticks, they could populate all the channels while keeping total memory capacity the same as other setups. I don't see why they had to splurge all the way up to 512GB.

Playing around with 96x avx512 sounds fun

Pardon my ignorance, I hear about "fun with avx512" so often yet still have 0 intuition about why its fun? What do people do with that instruction that's so different to all the other stuff?

I don't know when/if that change you talk about happened, as I banned LTT from my feeds years ago for their (subjectively) annoying style of presentation, but latest drama isn't even year old and highlighted so many technical issues with LTT I have no intention of trying them again:
