Upcoming high-performance laptops will tap into AMD’s Ryzen 7045 series (codenamed Dragon Range) portfolio. Benchmarks for the Ryzen 7 7745HX have surfaced, suggesting we could see these AMD-powered mobile powerhouses on store shelves soon.
In case you missed AMD’s CES 2023 announcement, Dragon Range is the first AMD mobile processor to leverage the company’s chiplet architecture. TSMC produces these chips for AMD using the 5nm FinFET manufacturing process. The 5nm processors come with the latest Zen 4 cores with configurations of up to 16 cores and 32 threads. If you pay close attention, the specs are in line with AMD’s desktop Ryzen 7000 (Raphael) processors. That’s no coincidence either.
AMD ported the Ryzen 7000’s chiplet design to Dragon Range, but reduced the overall landscape to a smaller BGA package that’s more user-friendly for mobile devices. Unfortunately, Dragon Range will use RDNA 2 graphics, but that should be fine as the iGPU is only there for light workloads. With the Dragon Range geared towards high-performance gaming laptops, vendors will in all likelihood pair the Zen 4 chip with a mobile discrete graphics card.
Ryzen 7 7745HX features a 16-thread setup with eight cores, a base clock of 3.6 GHz and a boost clock that reaches 5.1 GHz. It’s an unlocked processor, so user overclocking is on the table. There is 40MB of total cache on board, 8MB of L2 cache and 32MB of L3 cache.
The Ryzen 7 7745HX has a cTDP between 45W and 75W, allowing manufacturers to customize it to their needs. Dragon Range supports DDR5-5200 memory, and the Ryzen 7 7745HX specifically ships with the Radeon 610M unit with two RDNA 2 CUs that top out at 2,200MHz.

A Bilibili content creator (opens in a new tab) shared Cinebench R23 benchmarks for the Ryzen 7 7745HX. Be careful with the results as the user did not reveal the laptop they used or the test conditions. He only confirmed that the chip drew about 95W. AMD has confirmed that vendors have the freedom to feed Dragon Range up to 100W. The Cinebench R23 results we show for the comparable processors come from Notebookcheck’s database (opens in new tab), so credit goes to them for providing the results.
The Ryzen 7 7745HX showed 16% and 32% higher single-core and multi-core performance compared to the Ryzen 9 6900HX (8C/16T). The octa-core Zen 4 chip also outperformed Apple’s M2 Max (12C/12T) by 12% in single-core performance and 26% in multi-core performance. However, the Ryzen 7 7745X’s performance was quite similar to the Core i9-12900HK (14C/20T). AMD’s chip offered 2% better single-core performance, but both chips were equally fast on multi-core performance.
However, the Ryzen 7 7745HX was no match for the previous Core i9-12900HX (16C/24T) or the latest Core i9-13900HX (24C/32T). The Core i9-12900HX beat the Ryzen 7 7745HX by 5% and 24%, respectively, in single-core and multi-core performance. Meanwhile, the Core i9-13900HX’s single-core score was 12% better and its multi-core score was up to 62% higher than the Ryzen 7 7745HX. The Core i9-12900HX and Core i9-13900HX were at an advantage because they have more cores. However, the Ryzen 9 7845HX (12C/24T) or the Ryzen 9 7945HX (16C/32T) will likely compete with Intel’s chips.
