ROG CROSSHAIR X670E EXTREME Unboxing / Flagship Top Attack with Complete Accessories

For AMD players, AM5 promises to be used until 2025, which means that investing in a high-end, flagship motherboard can continue to upgrade the CPU in the next 3 years, which also gives players another reason to buy a flagship motherboard. And ROG’s top AM5, X670E motherboard ROG Crosshair X670E Extreme has the latest flagship specifications and expansion capabilities of current PCs.

Supports AMD Ryzen 7000, AM5 processors, provides dual-channel 4 DIMM DDR5 memory, supports up to 128GB memory capacity and higher DDR5 6400+ and EXPO overclocking memory; also has 2 PCIe 5.0 x16 slots to support single card x16, dual-card x8x8 channel splitting, and a PCIe 4.0 x4 slot for expansion of additional audio cards and capture cards.

There are basically 6 SATA ports on the storage surface, and both M.2_1 and M.2_2 use the CPU channel to support PCIe 5.0 x4 SSD, but M.2_2 is related to the shared channel of PCIeX16_1 and PCIeX16_2, that is to say, when M.2_2 is used PCIeX16_1 and PCIeX16_2 will switch to x8 and x4 channel bandwidth; in addition, the PCIe 5.0 M.2 interface card in the accessories can be installed in PCIeX16_2 to provide PCIe 5.0 x4 SSD expansion.

In addition, the ROG GEN-Z.2 expansion card can expand the PCIe 5.0 x4 SSD using the CPU channel of GEN-Z.2_1, and the PCIe 4.0 x4 SSD using the PCH channel of GEN-Z.2_2; that is to say, storage expansion In addition to 6 SATAs, there are 5 M.2 expansions, 4 of which support PCIe 5.0 x4 SSD.

The network is the latest specification of Marvell AQtion 10GbE + Intel 2.5GbE and Wi-Fi 6E; the sound effect is a combination of ROG SupremeFX 7.1 ALC4082 audio chip and ESS ES9218 QUAD DAC. In addition, the motherboard has a total of 22 USBs available, including 2 USB4 Type C, 2 USB 3.2 Gen 2×2 Type C, and 10 USB 3.2 Gen 2 super-full configurations.

ROG CROSSHAIR X670E EXTREME motherboard performance test / AI-optimized overclocking

In terms of performance tests, several common sets of CPU rendering, computer performance tests and game performance are used for testing. The processor uses AMD Ryzen 9 7950X, G.SKILL TRIDENT Z5 NEO DDR5-6000 16GBx2 and NVIDIA Geforce RTX 4090. The motherboard AI Optimized, PBO automatic function is used in the settings, and the radiator uses ROG STRIX LC II 280mm AIO water cooling. The following scores are for your reference.

Test Platform
Processor: AMD Ryzen 9 7950X
Memory: G.SKILL TRIDENT Z5 NEO DDR5-6000 16GBx2
Display Card: NVIDIA GeForce RTX 4090
System Disk: Solidigm P41 Plus 1TB PCIe 4.0 SSD

CINEBENCH R20 and R23 are developed by MAXON based on Cinema 4D and can be used to evaluate the 3D graphics performance of computer processors. It is also a common test software currently used to evaluate CPU computing performance.

The 7950X can achieve CPU 15109 CB in the R20 version test, and the R23 version also has a CPU 38915 pts result; the single-core performance has a performance of 766 pts and 1971 pts respectively.


AIDA64 memory and cache test, the memory uses G.SKILL TRIDENT Z5 NEO DDR5-6000 16GBx2, with the performance of memory read 74922 MB/s, write 75908 MB/s, copy 69744 MB/s, delay 74.6 ns.

The overall performance test of the computer is carried out with PCMark 10, which can be used to score the basic computer tasks of Essentials, such as App startup speed, video conferencing, and web browsing performance, while the Productivity productivity test uses spreadsheets and paperwork as test items. Digital Content Creation video content creation, it is tested by photo/video editing, rendering and visualization.

The 7950X with RTX 4090 scored 10,271 points, the computer benchmark performance Essentials has 12266 points, productivity has 12127 points, and the high score of 19766 points for digital content creation that requires more CPU operations; the recorded data shows that the CPU clock rate during the test is up to 5.8GHz.

PCMark 10.

3DMark CPU Profile is a test designed for processors. It mainly tests the CPU’s physical operations and custom simulation. Therefore, there will be different execution thread tests, because the number of execution threads used by different applications and games is different.

For example, under the Max threads test, the maximum performance of the CPU can be displayed, but this does not mean that games can also play the same performance, but movie-level rendering, simulation or scientific analysis applications will use the performance of the full execution thread; the same reason 16 threads also have better performance for computing and digital content creation, and have little impact on games.

The 7950X Max threads can reach a score of 16295, meeting the needs of movie-level rendering, simulation or scientific analysis applications, while the main gamers are 8 threads with 7676 points and 4 threads with 4167 points.
