AMD Ryzen 9 PRO 7940HS vs AMD Ryzen 7 7700

AMD Ryzen 9 PRO 7940HS

The AMD Ryzen 9 PRO 7940HS 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 4 (base) up to 5.2 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache.

Compared to the consumer Ryzen 9 7940HS, the PRO models offer additional security, manageability, and reliability features designed for professional users and workstation environments.

The performance of the R9 PRO 7940HS should be 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 7940HS 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 2.8 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.

AMD Ryzen 7 7700

The AMD Ryzen 7 7700 is a fast high-end desktop processor of the Raphael series. It offers 8 cores based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.8 (base) up to 5.3 GHz (single core boost). Compared to the faster Ryzen 9 CPUs (like the 7900X), the R7 offers less cores and slightly lower clock speeds.

The performance of the R7 7700 is slightly below the higher clocked AMD R7 7700X (that also features a higher TDP).

The Raphael series still uses a chiplet design with two CCD-clusters (each with 8 possible cores, so only one used for the 7700X) in 5nm and an IO-die (including the memory controller and the Radeon Graphics iGPU) in 6nm.

The Ryzen 7 7700 is rated at a TDP of only 65 Watt and therefore suited for smaller desktops (and cooling solutions).
