The Intel Core i5-1145G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1.1 GHz (12 Watt TDP) up to 2.6 GHz (28 Watt). The Boost is always specified at 4.4 GHz (one or two cores).
Another novelty is the integrated Xe graphics card with 80 EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake).
Furthermore, Tiger Lake SoCs add PCIe 4 support (4 lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wifi 6 in the chip. In addition to this, the i5 supports vPro for easy remote management.
The chip is produced on the improved 10nm SuperFin process at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).
The AMD Ryzen 5 PRO 7640HS is a fast mid-range laptop processor of the Phoenix series. It offers 6 cores (hexa core) based on the Zen 4 architecture that supports hyperthreading (12 threads). The cores clock from 4.3 (base) up to 5 GHz (single core boost). The processor includes 6 MB L2 cache and 16 MB L3 cache.
Compared to the consumer Ryzen 5 7640HS, the PRO models offer additional security, manageability, and reliability features designed for professional users and workstation environments.
The performance of the R5 PRO 7640HS is clearly lower (multi-threaded) than the higher end Ryzen 7 7840HS and Ryzen 9 7940HS models due to the two missing CPU cores. Compared to the faster HX series, the 7640HS at 54W TDP should be only slightly slower than the Ryzen 5 7645HX (also 6 Zen 4 cores, up to 5 GHz, 55W). The old Ryzen 5 6600H should be easily bested thanks to the improved architecture and higher clock speeds.
The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 760M with 8 of the 12 CUs and 2.6 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.
