The latest product that was tested out is the Zhaoxin KX-7000 CPU, an x86 chip designed for the domestic Chinese market. The CPU was launched at the end of 2023 and we saw the first products roll out in the first quarter of 2024. Early performance tests showed that the chip can reach performance similar to the Intel 10th Gen "Comet Lake" lineup which utilizes a refined version of the Skylake architecture and should also be able to match the first-gen Zen core architecture.

Starting with the specifications, the Zhaoxin KX-7000/8 CPU is based on the x86 Century Avenue architecture and features a 7nm chiplet design. The CPU die is separate from the I/O die with the CPU die measuring 78.6mm2 and the I/O die measuring 151.8mm2. The CPU die features 8 CPU cores with 8 threads, 512 KB of L2 cache per core (4 MB total), 32 MB of shared L3 cache, and a core clock of up to 3.6 GHz (3.2 GHz base).

The I/O die features the IMC which supports both DDR4-3200 and DDR5-4800 memory standards with up to 128 GB capacities, there's also an on-die GPU known as the C1190 which supports DX12, OpenCL 1.2, OpenGL 4.6, and H.265. The iGPU supports DP, HDMI, and VGA output interfaces. The rest of the blocks include 24 PCIe Gen4 lanes, 4 USB 3.2 Gen2, and a single USB4 controller. There's
