ASUS Republic of Gamers Announces ROG Strix SCAR 17 X3D, the World's First AMD Ryzen 9 7945HX3D Laptop


TAIPEI, Taiwan, July 28, 2023 — ASUS Republic of Gamers (ROG) today announced the new ROG Strix SCAR 17 X3D, the perfect fusion of cutting-edge silicon and ROG engineering. Featuring the AMD Ryzen™ 9 7945HX3D mobile processor equipped with AMD 3D V-Cache™ technology for the very first time, the Strix SCAR 17 X3D takes performance to a whole new level. By doubling the L3 cache of the mighty Ryzen 9 7945HX processor, the Ryzen 9 7945HX3D gives users a boost in games1 that are hungry for this onboard ultrafast memory. Paired with a 240 Hz QHD display, Conductonaut Extreme liquid metal on the GPU, and a vapor chamber, the Strix SCAR 17 X3D is ready to dominate the leaderboards.

Making great processors even better

While the original 2023 ROG Strix SCAR 17 came equipped with AMD Ryzen 7000 Series processors, the AMD Ryzen 9 7945HX3D is truly in a league of its own. It leverages the power of AMD 3D V-Cache technology, a stacking of extra ultra-high-speed L3 cache vertically on top of one of the two core compute dies (CCD). This extra cache enables the eight cores to perform certain calculations quickly and efficiently, notably in gaming. For situations where increasing CPU frequency simply doesn’t show significant performance gains, 3D V-Cache technology holds the potential to unlock extra compute power. When combined with top-tier graphics like the NVIDIA® GeForce RTX™ 4090 Laptop GPU, the new AMD Ryzen 9 7945HX3D processor is an average of 20% faster than the Ryzen 9 7945HX across select titles1. AMD Precision Boost Overdrive2 is also fully unlocked on this machine, a BIOS setting that allows gamers to overclock the CPU even further.

A perfect pairing

This new class of power is supported by the same ROG Intelligent Cooling ecosystem that keeps other Strix laptops performing at the top of their game. Conductonaut Extreme liquid metal has been applied to the GPU3 to offer up to 17X-better thermal conductivity than traditional pastes, while a full-cover vapor chamber provides next-level cooling performance not just to crucial chips like the CPU and GPU, but other components like the voltage regulator modules (VRMs). With 43.3% coverage of the total motherboard area, the vapor chamber on the 2023 Strix Scar 17 X3D is the best ROG Intelligent Cooling has to offer. Featuring the same bold and sporty chassis of the original SCAR 17, the ROG Strix SCAR 17 X3D offers plentiful RGB for customization ROG styling across the machine. Robust I/O, including dual USB Type-C® along with dedicated HDMI® 2.1 and 2.5G Ethernet ports allow this machine to act as a true battlestation when paired with an external display. When on the move, the QHD 240 Hz panel with G-SYNC® support is a joy to game on, with G-SYNC eliminating motion tearing, and NVIDIA Advanced Optimus driving more performance and lower latency than ever before. The Strix SCAR 17 X3D is here to win.

1 Based on testing by AMD as of 6/29/2023, with the following processors: Ryzen 9 7945HX3D vs. Ryzen 9 7945HX and Intel Core i9-13980HX. Configuration for the AMD systems: ASUS Strix Scar 17, 32GB (2x16GB) DDR5, 1TB SSD, GeForce RTX 4090 Graphics, Windows 11 64-bit. Configuration for the Intel Core i9-13980HX system: ASUS Strix Scar G16, 32GB (2x16GB) DDR5, 1TB SSD, GeForce RTX 4090 Graphics, Windows11 64-bit. Test results are based on average FPS scores in the following games: League of Legends, Total War: Warhammer 3, Strange Brigade, Middle Earth: Shadow of War, Borderlands 3, Riftbreaker, Final Fantasy 14, Deus Ex: Mankind Divided, F1 2021, Dirt 5, DOTA 2, Cyberpunk 2077. All tests run in turbo mode, 1080p native, at high details. System manufacturers may vary configurations, yielding different results. Performance may vary. DRG-13.

2 Precision Boost Overdrive requires an AMD Ryzen Threadripper, Ryzen 3000 Series (excluding Ryzen 3400G and 3200G) or newer desktop processor, or a Ryzen 9 7945HX3D mobile processor, and a compatible motherboard. Because using Precision Boost Overdrive enables operation of the processor outside of AMD’s published specifications, use of the feature invalidates the AMD product warranty and may also void warranties offered by the system manufacturer or retailer. Availability of Precision Boost Overdrive in pre-built OEM desktop systems will vary based on the PC manufacturer’s settings. Check with the PC manufacturer prior to purchase. GD-179.

3 ASUS does not use or recommend using liquid metal on the AMD Ryzen 7945HX3D processor because liquid metal may react with the backside metallization layer of the processor.
