Although AMD has only revealed its Ryzen 7040 HS-series CPUs for laptops and did not talk about the U-series, the Ryzen 5 7640U Phoenix 6-core APU has now been spotted in the Geekbench database. The same CPU has already appeared earlier when AMD was talking about the new naming scheme for its Ryzen 7000 series.

Based on AMD's Zen 4 core architecture and built on a 4 nm manufacturing process, the Ryzen 5 7640U features 6-cores and 12-threads, 6 MB of L2 cache, and 16 MB of L3 cache. According to the Geekbench listing, it works at 3.5 GHz base and 4.9 GHz boost clocks. It also comes with Radeon RX 760M, which is an RDNA 3 based iGPU with 8 Compute Units (CUs), which should leave it with 512 Stream Processors. As detailed earlier, the TDP is set at 15 W to 28 W, and it aims at the "Premium Ultrathin" market. Judging from these listed specifications, the Ryzen 7640U appears to be the same as the Ryzen 5 7640HS, probably just with lower clocks across the board due to the lower TDP.The listing at Geekbench shows what appears to be AMD's own reference platform called "Mayan-PHX," and it managed to get a pretty decent score of 1869 points in single-core and 8853 points in multi-core benchmark. When compared to the predecessor, the Ryzen 5 6600U, we are looking at an impressive performance gain in both benchmarks, depending on the platform. Of course, we still do not know the exact TDP that the reference platform was running at, so take these results with a grain of salt.In any case, the Ryzen 7040U series looks quite impressive and we hope that AMD will officially confirm these specifications, so we have a clearer picture what to expect from the "premium ultrathin" market.
