The Ryzen 5 7640U is a Phoenix family processor that was unveiled in H1 2023. The mid-range laptop chip has 6 SMT-enabled cores (12 threads) running at 3.5 GHz to 4.9 GHz. Those Zen 4 architecture cores are mated to the Radeon 760M integrated graphics adapter; the latter is about as fast as the aging Intel Iris Xe options.
Furthermore, the 7640U is one of the first AMD processors to support Ryzen AI which is AMD's answer to Intel's DL Boost and GNA technologies.
Architecture & Features
Phoenix family chips are powered by the Zen 4 architecture, much like Dragon Range family chips are. The latter however lacks hardware AI workload acceleration capabilities that Phoenix has.
More importantly, Zen 4 introduces AVX512 support (which Zen 3 chips did not have) and, thanks to a plethora of other improvements including larger caches/registers/buffers across the board, is set to deliver a double-digit IPC improvement.
Elsewhere, the 7640U has 16 MB of L3 cache and USB 4 support (therefore, Thunderbolt is supported as well). The chip is compatible with DDR5-5600 and LPDDR5x-7500 RAM which is really impressive as of H1 2023.
A system powered by this Ryzen 5 will have access to twenty PCIe 4 lanes; this means a speedy enough NVMe SSD will be able to deliver speeds up to 7.8 GB/s.
Systems powered by this APU are expected to run 64-bit Windows 11, 64-bit Windows 10, or Linux. Like most laptop chips, the 7640U is neither overclockable nor user-replaceable. It gets soldered down for good (FP7, FP7r2, FP8 socket interfaces).
Performance
While we have not tested a single system built around the 7640U as of December 2023, it's safe to expect the chip to be at least 10% faster than the Zen 3 Plus-powered Ryzen 5 6600U (6 cores, 12 threads, up to 4.5 GHz).
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your laptop is.
Graphics
The Radeon 760M has 8 CUs (512 shaders) running at up to 2,600 MHz. While not great for gaming (unless you are fine with resolutions such as 900p and low detail settings), the iGPU will let you use up to 4 monitors with resolutions as high as SUHD 4320p. It also HW-decodes and HW-encodes the most widely used video codecs including AV1, HEVC, AVC without breaking a sweat.
Power consumption
The 7640U has a long-term power limit (default TDP) of 28 W that laptop makers are free to change to anything between 15 W and 30 W. Either way, an active cooling solution is a must for any system powered by the chip.
Last but not the least, the 7640U is manufactured on TSMC's 4 nm process for high, as of late 2023, energy efficiency.
The Intel Core i5-1340P is a mid-range Raptor Lake-P (Alder Lake-P refresh) family CPU, a 28 W part meant for use in ultra-light, ultra-thin (yet actively cooled) laptops. This CPU was announced in early 2023 and it has 4 of the 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled and clock from 1.9 GHz (base) up to 4.6 GHz (single core boost) for a total of 16 threads when combined with the E-cores. The clock speeds of the E-cores ranges from 1.4 to 3.4 GHz and offer a similar performance as the old Skylake cores.
The performance should be similar to the old Core i7-1250P and therefore well suited for even demanding tasks.
The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
The i5-1340P is rated at 28 Watt tDP (PL1, 64 Watt PL2 for short bursts). The CPU is manufactured in the further improved Intel 7 process (10nm SuperFin).
