The AMD Ryzen 7 7840S is a fast high-end laptop processor of the Phoenix series. It offers 8 cores (octa core) based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.8 (base) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache. The processor is exclusively available in Lenovo laptops but the specs are similar to the regular Ryzen 7 7840HS.
The performance of the R7 7840S is only slightly below the fastest model, the R9 7940HS, as the clock speed difference is only minimal (e.g. -100 MHz / 2% slower single core boost). Therefore, the CPU should also perform slightly higher than the old top model Ryzen 9 6980HX (8 Zen 3 cores with up to 4.9 GHz) at 54W TDP and Ryzen 9 6980HS at 35W TDP. Compared to the higher end Dragon Range series, the 7840HS should be similar to the Ryzen 7 7745HX (also 8 Zen 4 cores, max 5.1 GHz, 55W TDP, 32 MB L3).
The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 780M with 12 CUs and up to 2.7 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding, a new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) that should be faster than the AI engine in the Apple M2 SOC and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support). The connectivity features includes 2 possible USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.
The Phoenix series uses a single monolithic design (unlike the chiplet design of the 7045HX series) and is manufactured in the modern 4nm process at TSMC. The TDP can be configured between 35 and 45 Watt.
The Intel Core i5-1350P 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 between 1.9 GHz (base) to 4.7 GHz (single core boost) for a total of 16 threads when combined with the E-cores. The E-cores clock from 1.4 to 3.5 GHz and offer a similar performance as the old Skylake cores.
The performance should be similar to the old Core i7-1260P and therefore well suited for even demanding tasks.
The CPU now supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
The i5-1350P 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).
