Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com, July 2, AMD officially released 7040U series processors in May this year, including R7 7840U and other four models, ranging from 4-core to 8-core models.

R7 7840U:8C16T 5.1GHz + 12CU 2.7GHz

R5 7640U:6C12T 4.9 GHz + 8CU 2.6GHz

R5 7540U:6C12T 4.9 GHz + 4CU 2.5GHz

R3 7440U:4C8T 4.7GHz + 4CU 2.5GHz

The up master @ Golden Pig upgrade package releases the latest Phoenix2 look and feel. You can clearly see from the figure that the Phoenix2 of the right 6C12T+4CU is much smaller than the Phoenix of the 8C16T+12CU on the left.

In addition, we can see that both use the same FP7 encapsulation, but Phoenix can actually use a slightly larger encapsulation specification such as FP8.

According to VideoCardz, the R7 7840U and R57640U (Phoenix) CCD chip area is up to 178mm ², while the R3 7440U and some R57540U use 137mm ²CCD chip (Phoenix2), which is about 23% smaller.

Sources said that the Phoenix2 series processors use the Zen4c architecture (CTOnews.com Note: architecture design is the same as Zen4, but lower frequency), CPU up to 6 cores, kernel shows the highest 4CU.

At present, the devices with R7 7840U, R57640U and R57540U have been put on the market one after another, while the devices with R37440U are not yet on the market.
