They simply aren’t viable because such configurations lack the necessary power and stability for practical use.

For tasks needing single-thread performance or low core counts, high-frequency applications like AutoCAD or Minecraft servers, you should consider an extremely powerful i9 with a single-core boost exceeding 5+GHz. However, this often means spending a lot for cores you won’t use. A dual-core CPU would be more practical, such as an i3, which tops out around 4.5GHz. The reason lower-end CPUs don’t reach the same speeds is usually due to manufacturing issues—defective dies or partial failures. It’s possible to select CPUs with some defective cores, but only a few would actually deliver full performance.
This can imply those chips struggle to maintain consistent performance at higher frequencies. Creating high-performance, low-core-count designs is becoming less appealing because of market needs. The thermal design power (TDP) also poses challenges—justifying a 120W+ TDP for a quad-core processor is difficult, and heat dissipation becomes more problematic due to reduced surface area.
Due to chip binning, heat and power usage would become excessively high. AMD provided three versions of the 3600 series. The 3600 model is relatively poorly binned, while the 3600X offers much better binning, and the 3600XT represents the top binned six-core Zen2 CPU.
They’re trying to make you spend more money. "Wanna get a dual-core processor that delivers 4.8Ghz consistently? That’s a big ask! You’ll need to invest in an i7/R7 level CPU if you really want those speeds. Please."
It feels like the most probable explanation to me. After all, that’s the way capitalism functions, so I’m not placing blame on anyone.
It's mainly due to one factor, though there might be others. The chance of failure for premium chips could be lower, which means there aren't enough "dual cores with high clock speeds" to launch a real product. For instance, if an i9/R9 doesn't meet its requirements, it might still work with i7/R7, i5/R5, or i3/R3 before being downgraded to basic dual-core options.
The factors involved are more intricate... they relate to the expenses of producing silicon chips, the design choices and data flow within processors, etc. For instance, AMD aimed for better pricing and reliability by adopting 4-core designs in Zen 3, transitioning to 8 cores. They optimized memory controllers, PCIe interfaces, and specialized IO chips using cost-effective manufacturing methods. These components could be mass-produced efficiently and grouped into various product lines. High-performance options like Threadripper follow, then 16-core processors such as the 5950X. Standard chips with names like X offer a balance of speed and overclocking potential, while those with weaker transistors or cores are marketed without those identifiers. Some designs include faulty elements—like defective cache memory or inefficient cores—to reduce costs. To achieve top speeds, engineers plan from the outset for minimal cores and smart cache placement, ensuring data is near processing units. Fast RAM is also crucial; otherwise, even rapid calculations stall due to slow data retrieval.
It's fascinating how much has changed over the years. Remember when X86 began in MHz instead of GHz? Still, modern chips are incredibly powerful. Every new update brings us closer to what we need. Twenty years ago, a 5GHz chip seemed like science fiction. Back then, having 16 cores was a dream. Now it's standard. A 4.5GHz processor is quite impressive. However, thermal limits and design constraints still play a role. Not all systems use liquid nitrogen for speed. For context, my 8700K would require 6GHz in liquid nitrogen to match the performance of a 4.8GHz 5600X under normal cooling conditions. High-speed processors exist, and even lower-frequency ones like the 12100F are impressive. But 4.5GHz is just typical today, and those who haven't seen it yet can't fully appreciate how far we've come from the early days of single-core processing.
You might consider a Z series board that allows bclk OC on locked chips and fit an i3-12100. However, such boards are limited in number, costly, and only support DDR5. The pricing makes sense if you opt for a more affordable Z690 and a 12600KF.
