After years of delays, Chinese chipmaker Zhaoxin has finally launched its long-awaited KX-7000 series consumer CPUs, only one of its kind in China, based on the licensed x86-64 ISA. Zhaoxin claims the new 8-core processors based on "Century Avenue" uArch deliver double the performance of previous generations. Leveraging architectural improvements and 4X more cache, the KX-7000 represents essential progress for China's domestic semiconductor industry. While still likely lagging behind rival AMD and Intel chips in raw speed, the KX-7000 matches competitive specs in areas like DDR5 memory, PCIe 4.0, and USB4 support. For Chinese efforts to attain technological independence, closing feature gaps with foreign processors is just as crucial as boosting performance. Manufactured on a 16 nm process, the KX-7000 does not use the best silicon node available.
Other chip details include out-of-order execution (OoOE), 24 PCIe 4.0 lanes, a 32 MB pool of L3 cache and 4 MB L2 cache, a base frequency of 3.2 GHz, and a boost clock of 3.7 GHz. Interestingly, the CPU also has VT-x, BT-d 2.5, SSE4.2/AVX/AVX2 support, most likely also licensed from the x86 makers Intel and/or AMD. Ultimately, surpassing Western processors is secondary for China next to attaining self-reliance. Instructions like SM encryption catering to domestic data protection priorities underscore how the KX-7000 advances strategic autonomy goals. With its x86 architecture license giving software compatibility and now a vastly upgraded platform, the KX-7000 will raise China's chip capabilities even if it is still trailing rivals' speeds. Ongoing progress closing that performance gap could position Zhaoxin as a mainstream alternative for local PC builders and buyers.
