Farewell to I/A/N! Domestic LX7G100 + Zhaoxin KX7000 Actual Test: Cyberpunk 2077 Over 30 FPS

YouTube blogger GPUSpecs recently released a video, using the Lishuan LX7G100 GPU paired with the Zhaoxin KX7000 octa-core CPU to build a gaming PC without any Intel, AMD, or NVIDIA chips, and tested the performance of several AAA titles.

The core configuration of this system includes the Zhaoxin KX7000 processor (8 cores, 3.7GHz clock speed) paired with 16GB DDR4 memory, and the GPU is the Lishuan LX7G100.

The LX7G100 is built on a 6nm process, features 6,144 cores, 12GB GDDR6 VRAM, with a TDP of 225W, and is the first domestic GPU to receive Microsoft WHQL driver certification.

Previously, this blogger tested the Moore Threads MTT S80 with the same Zhaoxin CPU. After switching to the LX7G100, the frame rate improved significantly, and the bottleneck shifted to the CPU side.

In terms of actual test data, Forza Horizon 5 averaged 62.5 fps at 1080p low settings, Resident Evil 3 averaged 67.2 fps at 1080p, Shadow of the Tomb Raider in DX12 mode averaged 62 fps at 1080p maximum settings, Red Dead Redemption 2 averaged 39 fps at 1080p medium settings, Cyberpunk 2077 averaged 32.8 fps, and Black Myth: Wukong averaged 30 fps at 1080p low settings.

However, performance in DX11 games was poor. Shadow of the Tomb Raider in DX11 mode only achieved about 15 fps, GTA V at 1080p maximum settings managed 12.1 fps, and Rocket League at 1080p high settings only reached 33.7 fps.

The CPU is another bottleneck of the entire system. The Zhaoxin KX7000's 3.7GHz clock speed is relatively low, and after unleashing the LX7G100's performance, it actually became a hindrance.

However, Zhaoxin is not the strongest option among domestic CPUs. The Hygon C86-4G is reportedly on par with Intel's Core i7 Raptor Lake series. If a newer domestic CPU is used, the CPU bottleneck issue is expected to be alleviated.

Overall, building a gaming PC capable of playing AAA titles using entirely domestic CPUs and GPUs is no longer a pipe dream, provided that games supporting modern APIs like DX12 are chosen. DX11 legacy games remain a weak point due to driver optimization limitations.
