Can not compare one bench with another.
I doubt they will use old processors...

I gather that Intel has dumped AVX-512 to remain competitive on power/speed with AMD.

As far as I understood, some of the CPU cores of the 12th gen Intel CPU's can't do AVX-512 at all, so they have to scratch it because of that.

Some plug-ins uses AVX-512 like Melda, 2CAudio, I guess Acoustica Audio Acqua
and probably others...

Is there some kind of "fallback" for those plugins? My CPU can't do AVX-512, and, I haven't run into any problems yet... I have some of Melda's plugins.

Yes, they use AVX2 if no AVX-512 is available.

Thanks.

My point exactly. So the link you provided doesn't address the situation I'm afraid. Old processors would be beneficial in measuring improvements over CPU generations. It's too bad they don't open this to end users like the other performance benchmarks and use them in some way to average performance per CPU in their charts.

The lower power (lower transistor count) "efficiency" cores lack the silicon for the AVX-512. However, the P cores have those instructions and can actually be kicked into action with certain BIOS hacks etc according to some tech site articles I have seen. This seems to be some sort of corporate decision by Intel brass to nix these instructions altogether despite the fact that the silicon is there (they already spent your money on it) and it can actually operate.

I wondered if this is because Intel want these chips to reach certain benchmarks inside a given power and thermal envelope and to hell with the lost capability. Given that OS threading has to be tweaked to manage the two different types of core in any case it seems these could be used if they wanted to allow that. Also, they could sell chips entirely made of P cores for high performance applications. My impression is that marketting considerations are the main thing here.

I just found someone who has actually written about building a new 12th GEN Intel system with DDR4 and most importantly for me, uses Ableton.

It seems to work very well for this person. It would be interesting to see this computer running Ableton 11 with more than 16 tracks and check how well it's making use of all the cores.

The largest project I checked is one with ~20 track -- with lots of Kontakt sample instruments, VSTs instruments, audio tracks and effects... the processor usage was spread across the threads pretty evenly, with plenty of CPU headroom left open. The interface is really snappy, and has been extremely stable so far.

What I do not like in his build is the CPU cooler.

Nice to see some new numbers from Scan Audio. Pictus what are your thoughts on the efficiency benefits of the Ryzen 7000 series vs the latest Intel? Does it matter in an audio context? I mean if you have the appropriate powersupply and cooling is that really a factor outside of power draw or heat (say in a small studio space)?

[Pictus]

It is a "cat and mouse" game between Intel and AMD.

Ignoring the price, today I would take the AMD 7000 and use it in "ECO Mode".
I would adjust the CPU wattage to fit the capacity of my cooling system.

Those 7950 @ 65W numbers mean there's some hope I might avoid Apple Silicon yet! No surprise they released it with defaults designed to beat 12900k benchmarks though. But barely dropping 25% multi-core @ 65w is the much bigger story. It would be nice to see some audio tests with the 7950 in a 65W config.

Of course, buying means you don't get to ignore the price. Whilst it's possible we'll see an early price drop (in response to Intel's 13th gen) the other issue is the motherboards appear to be hugely expensive. I don't mind the move to DDR5 - Apps, like Kontakt, seem to get a decent performance benefit from it. But Gamers Nexus made a rather concerning comment - Saying that the sky high pricing did not appear to be reflected in the build quality of the boards they had in for testing. Not good. Supposedly PCIe Gen 5 implementation is one culprit in the higher costs. But enough to make for 2x or 3x price increases?!?
