AMD Ryzen Z1 APU series can operate with 9W TDP

AMD Ryzen Z1 APUs TDPs is going as little as 9W


It’s no secret that Ryzen Z1 and Ryzen 7040U sequence are an identical. Each processor traces are the use of the similar silicon codenamed Phoenix in keeping with Zen4 and RDNA3 structure, however there are small variations that make the Z1 an excellent resolution for hand-held gaming, which is its major goal.

(*5*)Tom’s {Hardware} reached out to AMD for a remark at the topic, and so they discovered that there are variations relating to energy levels voltage curves. The reputable observation from Matthew Hurwitz (AMD PR) didn’t point out any bodily adjustments to the die itself:

“The Ryzen Z1 sequence are purpose-built with hand-held gaming in thoughts. To perform this, AMD engineers needed to validate solely new energy levels and optimize the voltage curves in particular for this use case – this optimization and validation paintings must no longer be trivialized. So whilst the era construction blocks (like ‘Zen4’ and RDNA 3) are an identical between the 7040 and Z1 sequence, the ensuing fashions have very distinct traits custom designed for his or her use circumstances. As well as, the AMD Ryzen AI engine isn’t to be had on AMD Ryzen Z1 sequence processors.”

AMD spokesman later showed that the Configurable Thermal Design Energy (cTDP) is going as little as 9W, that’s in truth less than Ryzen 7040U sequence which formally pass as little as 15W. The corporate had already up to date the web site to replicate this alteration, alternatively do be aware that there are nonetheless no reputable clock speeds showed for the Z1 sequence.

Naturally, this doesn’t imply Ryzen 7040U can not perform at decrease energy as neatly, as a result of TDP isn’t the similar factor as energy intake. The TDP merely units a goal for the CPU voltage/frequency curve, which within the case of 7040U sequence is optimized for 15W. The Z1 sequence with TDP of 9W required further validation, and it was once sufficient to tell apart the sequence beneath a brand new identify.(*8*)(*3*)(*7*)

The primary product in keeping with Ryzen Z1 is ready to be introduced on Would possibly eleventh. ASUS ROG Best friend is to this point the one recognized hand-held console to function this CPU, whilst different console makers depend at the 7040U sequence as a substitute.
