AMD Ryzen 7 7840HS Processor

AMD R7 7840HS

The AMD Ryzen 7 7840HS is a posthaste high-stay notebook computer processor of the Phoenix sequence. It provides 8 cores (octa core) in accordance to the Zen 4 architecture that helps hyperthreading (16 threads). The cores clock from 3.8 (heinous) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache.

The performance of the R7 7840HS is easiest impartial under the fastest mannequin, the R9 7940HS, because the clock tempo incompatibility is easiest minimal (e.g. -100 MHz / 2% slower single core boost). Therefore, the CPU might perhaps well perhaps light moreover originate impartial a little increased than the aged top mannequin 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 increased stay Dragon Fluctuate sequence, the 7840HS must be linked to the Ryzen 7 7745HX (moreover 8 Zen 4 cores, max 5.1 GHz, 55W TDP, 32 MB L3).

The chip integrates a up to the moment and fasts RDNA 3 graphics card (iGPU) called Radeon 780M with 12 CUs and 2.9 GHz clock tempo. Moreover, the Phoenix sequence embody a video engine with AV1 de- and encoding, a brand new Xilinx FPGA basically basically based XDNA AI accelerator (Ryzen AI) that must be faster than the AI engine within the Apple M2 SOC and a twin-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC beef up). The connectivity capabilities includes 2 potential USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.

The Phoenix sequence makes exhaust of a single monolithic manufacture (now not like the chiplet manufacture of the 7045HX sequence) and is manufactured within the stylish 4nm job at TSMC. The TDP might perhaps well perhaps very successfully be configured between 35 and forty five Watt.
