In context: AMD announced its Ryzen 7040 ‘Phoenix’ CPUs for laptops earlier this year, but the lineups are currently limited to just the ‘HS’ and ‘H’ variants. The company is expected to launch U-series chips for thin and light laptops, 2-in-1s, and ultrabooks later in 2023.
Leaked benchmarks of AMD’s Ryzen 5 7640U ‘Phoenix’ mobile CPU have revealed several critical details, including impressive clock speeds. First stained by whistleblower @BenchLeaks, the Geekbench 5 benchmark shows an average single-core score of 1,869 and a multi-core score of 8,853, both of which are substantially faster than its predecessor, the Ryzen 5 6600U.
The 6600U scores around 1,600 points in the single-core benchmark test and around 5,500 points in the multi-core benchmark test, meaning the new chip could be up to 33% faster in single-core applications and 50% faster in multi-threaded applications. Workload
As the tipster pointed out, the single-core score is also 8.2% faster than the Ryzen 7 5800X, although the multi-core score is 17.6% lower, mainly due to fewer cores. .

The new chip was tested on the ‘Mayan-PHX’ system, which is likely to be an AMD reference and validation platform rather than a retail product. The system had 16 GB of RAM and was running Windows 11 Pro.
As for the hardware specs, the Geekbench listing suggests the new chip will feature 6 cores, 12 threads, 6MB L2 cache, and 16MB L3 cache. The 7640U will also come with integrated Radeon 760M graphics, which means it will be more like a reworked 7640H(S) but with a lower TDP of around 15-28W, since it’s part of the ‘U’ series.
However, the most interesting thing is the clock speeds. While the base frequency of the Ryzen 5 7640U is said to be 3.5GHz, the boost clock is listed at a whopping 4.89GHz. The super-high boost clock is a bit of a surprise, given the efficiency of the chip.
AMD had previously revealed that the Ryzen 5 7640U will be based on its Zen 4 core architecture fabricated on the 4nm process node. However, this is the first time its specs have been leaked, revealing its core configuration, clock speeds, iGPU, and other critical specs. For now, there’s no word on when this will be officially announced, but online speculation suggests it could happen at Computex 2023 in May.
