If an AMD laptop supports 4266 MHz LPDDR4X, where can one actually buy one to upgrade their RAM?

LPDDR RAM is not upgradeable. It is soldered to the motherboard, be it on laptops, smartphones or tablets.

MCLK= memory clock, UCLK= memory controller clock, FCLK=Fabric clock

According to the twitter discussion,  if the CPU is in high power state,  AMD sets FCLK:UCLK:MCLK ratio to 1:1:1, all at 1333MHz, so all are synchronized for best transfer rate.

If GPU is in high power state, they raise MCLK to 2133MHz , but dial back UCLK and FCLK to allocate more power to GPU.  In particular UCLK to 1067MHz.

So ... looks like working around thermal issues with whatever levers they have.

Intel CPUs have had dynamic frequency scaling for years now. Called SAGV. So I don't think you statement is true.

Users only need to care and compare the use results, otherwise smart designs will be discouraged.

One smart design is Intel's using partial addresses, faster and less silicon, and nobody cares, even so-called reviewers and techies :-)

Userbench? You should ban that benchmark/site even if it does, sometimes, post interesting results.

UserBench...... If AMD then final_score = score*0.75

 We'll see when reviews come

Well, perhaps the lowered ddr clocks  are necessary due to the raised GPU clock in Renoir.

I noticed some reviews of Renoir where dimming the screen was considered an acceptable optimization.
