Ryzen 7 7745HX, 8-Core Laptop CPU Is as Fast as 14-Core, Core i9-12900HK

Future high-performance laptops will tap into AMD’s Ryzen 7045-series (codename Dragon Range) range. Benchmarks for the Ryzen 7 7745HX have emerged, hinting that we could soon see these AMD-powered mobile powerhouses on store shelves.

If you missed out on AMD’s CES 2023 announcement, Dragon Range is the first AMD mobile processor to utilize the company’s chiplet architecture. TSMC provides these chips for AMD on the 5nm FinFET manufacturing technology. The 5nm processors arrive with the latest Zen 4 cores with configurations of up to 16 cores and 32 threads. If you pay close attention, the specifications coincide with AMD’s desktop Ryzen 7000 (Raphael) processors. That’s no coincidence, either.

AMD moved the chiplet design from Ryzen 7000 across to Dragon Range but shrunk the entire landscape into a smaller BGA box that’s more suited for mobile devices. Regrettably, Dragon Range will wield RDNA 2 graphics, but that should be alright as the iGPU is only there for mild workloads. As Dragon Range specializes to high-performance gaming laptops, suppliers will, in all likelihood, match the Zen 4 CPU with a mobile discrete graphics card.

Ryzen 7 7745HX has an eight-core, 16-thread setup with a 3.6-GHz base clock and a boost clock that reaches 5.1 GHz. It’s an unlocked processor, so user overclocking is on the table. There’s 40MB of total cache onboard, 8MB from the L2 cache, and 32MB from the L3 cache.

The Ryzen 7 7745HX has a cTDP between 45W and 75W, permitting manufacturers to adapt it to their needs. Dragon with the Radeon 610M unit with two RDNA 2 CUs that top out at 2,200 MHz.

Processor Cinebench R23 Single Core Cinebench R23 Multi Core
Core i9-13900HX 2,043 30,162
Core i9-12900HX 1,912 23,150
Ryzen 7 7745HX 1,828 18,606
Core i9-12900HK 1,789 18,621
Apple M2 Max 1,625 14,767
Ryzen 9 6900HX 1,570 14,085


The Ryzen 7 7745HX showed 16% and 32% greater single-core and multi-core performance, respectively, over the Ryzen 9 6900HX (8C/16T). The octa-core Zen 4 processor also surpassed Apple’s M2 Max (12C/12T) by 12% in single-core performance and 26% in multi-core performance. Nonetheless, the Ryzen 7 7745X’s performance was pretty much in the same ballpark as the Core i9-12900HK (14C/20T). AMD’s processor delivered 2% greater single-core performance, while both CPUs were similarly fast in multi-core performance.

Unfortunately, the Ryzen 7 7745HX was no match for the prior Core i9-12900HX (16C/24T) or the current Core i9-13900HX (24C/32T). The Core i9-12900HX topped the Ryzen 7 7745HX by 5% and 24% margins in single-core and multi-core performance, respectively. Meanwhile, the Core i9-single-core 13900HX’s score was 12% better, and the multi-core score went up to 62% higher than the Ryzen 7 7745HX. The Core i9-12900HX and Core i9-13900HX had the advantage because they wield more cores. But, the Ryzen 9 7845HX (12C/24T) or the Ryzen 9 7945HX (16C/32T) will undoubtedly give Intel’s chips a run for their money.
