The last I checked, AMD was outperforming Apple perf/dollar on the high end, though they were close on perf/watt for the TDPs where their parts overlapped.
I’d be curious to know if this changes that. It’d take a lot more than doubling cores to take out the very high power AMD parts, but this might squeeze them a bit.
Interestingly, AMD has also been investing heavily in unified RAM. I wonder if they have / plan an SoC that competes 1:1 with this. (Most of the parts I’m referring to are set up for discrete graphics.)

- hedora 2y agoThat’s a laptop part, so it makes different tradeoffs. Somewhere on the internet there is a tdp wattage vs performance x-y plot. There’s a pareto optimal region where all the apple and amd parts live. Apple owns low tdp, AMD owns high tdp. They duke it out in the middle. Intel is nowhere close to the line. I’d guess someone has made one that includes datacenter ARM, but I’ve never seen it.

- aurareturn 2y agoHigh TDP? You mean server-grade CPUs? Apple doesn't make those.
- derefr 2y agoTrue, but these "Ultra" chips do target the same niche as (some) high-TDP chips. Workstations (like the Mac Studio) have traditionally been a space where "enthusiast"-grade consumer parts (think Threadripper) and actual server parts competed. The owner of a workstation didn't usually care about their machine's TDP; they just cared that it could chew through their workloads as quickly as possible. But, unlike an actual server, workstations didn't need the super-high core count required for multitenant parallelism; and would go idle for long stretches — thus benefitting (though not requiring) more-efficient power management that could drive down baseline TDP.
- aurareturn 2y agoOh you. mean Threadripper. I thought you were talking about Epyc. Anyway, I don't think it's comparable really. This thing comes with a fat GPU, NPU, and unified memory. Threadripper is just a CPU.
- mort96 2y agoThe GPU and NPU shouldn't be consuming power when not in use. Why shouldn't we compare M3 Ultra to Threadripper?
- diggan 2y agoIsn't the rack-mounted Mac Pro supposedly "server-grade" (https://www.apple.com/shop/buy-mac/mac-pro/rack https://www.apple.com/shop/buy-mac/mac-pro/rack)? At least judging by the mounts, they want them to be used that way, even though the CPU might not fit with the de facto industry label for "server-grade".
- aurareturn 2y agoServer grade CPUs. I thought he was referring to Epyc CPUs.
- jjcob 2y agoThe rack mount Mac Pro doesn't really make sense for a data center. It's 5U high, which is much too big for a data center. It doesn't have standard server features like redundant power supplies. The only use case I can think of is for audio workstations, where people have lots of rack mount equipment, so you can have everything including the computer in the rack. But even for that use case it's quite big.

- nick_ 2y agoSame. I'm not sure what to make of the various claims. I personally defer to this table in general: https://www.cpubenchmark.net/power_performance.html https://www.cpubenchmark.net/power_performance.html. I'm not sure how those benchmarks translate to common real world use cases.
