The AMD Ryzen 7 7840U is a quick high-end laptop computer processor of the Phoenix sequence and the fastest mannequin of the U-series. It provides eight cores (octa-core) based mainly on the Zen 4 structure that helps hyperthreading (16 threads). The cores clock from 3.3 (base) as much as 5.1 GHz (single core increase). The processor has an 8 MB L2 and 16 MB L3 cache.

The efficiency of the R7 7840U relies on the workload, which is barely beneath the Ryzen 7 7840HS (more incredible base clock velocity and TDP). Compared with the earlier era Ryzen 7 PRO 6850U, the 7840U is sooner due to the Zen 4 structure and better clock speeds.
The chip integrates a contemporary and fast RDNA 3 graphics card (GPU) known as Radeon 780M with 12 CUs and as much as 2.7 GHz clock velocity. Moreover, the Phoenix sequence embodies a video engine with AV1 de- and encoding, a brand new Xilinx FPGA-based mostly XDNA AI accelerator (Ryzen AI) that needs to be sooner than the AI engine within the Apple M2 SOC, and a dual-channel DDR5-5600 / LPDDR5x-7500 reminiscence controller (with ECC assist). The connectivity options consist of 2 doable USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.
The Phoenix sequence uses a single monolithic design (unlike the chiplet design of the 7045HX series). It is manufactured within the trendy 4nm course at TSMC. The TDP might be configured between 15 and 30 watts.
