Multicore designs employ multiple threads, while singlecore relies on just one thread, which may not accurately reflect thermal efficiency.
The thermal design of the Ryzen 7000 series was subpar, causing significant heat buildup. It stays manageable at around 80% capacity for about 15 to 20 minutes.
I've experienced numerous CPUs over the years, and air cooling solutions from the 80s have generally struggled under load once temperature monitoring became standard. Don't confuse the fact that better performance is possible with direct-die cooling for a flawed design. If they can meet their promised speeds, the issue lies elsewhere. Especially with technologies like the 3D V-Cache, you're still constrained by the thermal boundary between the CPU die and the cache module.
It's super far from a "hot take" AMD went out of their way to make AM5 compatible with AM4 and earlier CPU Coolers, and as a result the IHS is SUPER THICK. This ends up causing the cores to run really warm. The 7800X3D is a sub-90W part at full-load as shown in multiple reviews. There's NO fuckin' reason that should be running at 80+ under an intelligent design. AM5 has a shitty IHS design, and as a result the CPUs had to be "Designed to run at 95c, at the edge of throttle temps!" or whatever they're saying now.
I understand this point, though many so-called specialists I respect don’t rely as much on their opinions. It seems Gamers Nexus highlighted the intricacies of heat spreaders. Simply thinning them doesn’t improve efficiency; you still need sufficient material to absorb heat and distribute it evenly across the heatsink. Otherwise, hot spots form. True efficiency comes from direct-die cooling with a custom heatsink or waterblock tailored to the design. Heat spreaders often represent a trade-off between compatibility and performance, while also protecting the cores from damage. The challenge lies in managing this delicate balance.
