China's Domestic Zhaoxin KX-7000 8-Core CPU Matches Skylake In Single-Core, Beats It In Multi-Core Tests In Stock & OC Benchmarks

The Chinese domestic x86 chip, the Zhaoxin KX-7000 CPU, has been benchmarked in a wide range of tests at stock and overclock settings, showing a huge performance increase over the previous generation while the domestic market is still under pressure. Also offers a new option for PC needs.

Zhaoxin KX-7000 x86 CPU Tested: First Die Shots, LGA 1700 Socket Motherboards from ASUS, Overclock Benchmarks and More

The latest Zhaoxin KX-7000 CPU performance benchmarks come from ASUS China General Manager, Tony Yu, who Routinely conducts in-depth performance tests and product testing. On his official Bally channel.

The latest product tested is the Zhaoxin KX-7000 CPU, an x86 chip designed for the domestic Chinese market. gave CPU was launched in late 2023. And we saw the first product roll out in the first quarter of 2024. Early performance tests show that the chip can and should be capable of reaching similar performance to Intel's 10th Gen “Commit Lake” lineup, which uses an improved version of the Skylake architecture. To match the first generation 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 separated from the I/O die with the CPU die measuring 78.6mm2 and the I/O die measuring 151.8mm2. The CPU die includes 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 IMC that supports both DDR4-3200 and DDR5-4800 memory standards with capacities up to 128 GB, there is also an on-die GPU called C1190 that supports DX12, OpenCL 1.2, OpenGL 4.6, and supports H .265. The iGPU supports DP, HDMI, and VGA output interfaces. The remaining blocks include 24 PCIe Gen4 lanes, 4 USB 3.2 Gen2, and a USB4 controller. There is also a single SATA III controller for 4-port support.

Now for the design of the Zhaoxin KX-7000/8 CPUs themselves, the CPU manufacturer has decided to go with a similar design as the LGA 1700 socketed chips from Intel and both the design and IHS look the same.

The difference is at the bottom of the IHS and at the back of the PCB. The back caps are very different from the caps featured on Intel's LGA 1700 CPUs, and Intel also uses monolithic packages instead of chiplets for its current lineup. You can fit Zhaoxin CPUs on LGA 1700 motherboards designed for Intel CPUs but they are unlikely to boot up.

Coming to the platform, ASUS has developed its own dedicated LGA 1700 socketed motherboards for the Zhaoxin KX-7000/8 CPUs. The motherboard is similar to the entry-level offerings with a 6+2-phase VRM without any heatsinks, a single M.2 slot, two SATA III ports, two full-length PCIe x16 4.0, and one PCIe x1 4.0 slot.

The motherboard comes in MATX form factor and has only 2 DIMM slots. There is a debug LED on the motherboard and the I/O is very standard. The motherboard also lacks a PCH because all connectivity is handled by the I/O die on the CPU itself.

Moving on to performance figures, the CPU was first tested at stock and scored double the performance of its predecessor, the KX-6780, in both single and multi-threaded tests. The CPU was also on par with the Core i7-7700K and managed to outpace the AMD Ryzen 7 1700X in single-core tests.

The CPU can also be overclocked to 3.6 GHz (All-core) from its 3.6 GHz (Max 1-Core) and 3.2 GHz (All-core) clocks. This required a better cooling solution and a 360mm AIO was used.

This resulted in a 21% increase in multi-core and a 10% increase in single-core tests, which is significant. As for stock power, the CPU consumes 85W in multi-threaded tests.

While application performance was pretty decent, gaming performance still seems to need a lot of optimization work as the CPU can barely handle the NVIDIA GeForce RTX 4070 GPU. It was only able to manage 46 FPS at 4K in Cyberpunk 2077 and only 30 FPS in Counter-Strike 2 with severe GPU bottlenecks.

Finally, it is concluded that Zhaoxin KX-7000/8 CPUs are a good alternative for the Chinese domestic market and progress for x86/CPU development in Mainland China. The company expects to expand its family with chiplet offerings offering 16 or more covers.

Also, ASUS is saying that while they have set an upper limit for OC in their motherboards at 4 GHz, this limit can be increased to 5 GHz for extreme overclocking. ASUS Tony says that if the video reaches 100,000 likes he will ask his team at ASUS to update the BIOS so that's an interesting proposition.
