What the top Chinese KaiXian KX-U6780A processor can do compared to Intel and AMD CPUs

The import substitution direction has been actively developing in China for many years. The Chinese have got their own full-fledged x86-compatible processors with good performance. They are produced by Zhaoxin. Today we will see what a fresh eight-core KaiXian KX-U6780A is capable of. 


This CPU is also designed for the consumer market and has recently appeared in Chinese retail. The vendor claims that KX-U6780A matches the performance of Core i5-7400, which has only four cores and no support for Hyper-Threading. By modern standards, the processor is budget-priced, but for normal tasks its performance is quite enough. Is KX-U6780A really equal to Core i5-7400?

The KX-U6780A processor has eight cores, does not support hyper-threading technology, runs at 2.7 GHz, has 8 MB of layer 2 cache memory and supports DDR4-2666 (dual channel controller). The CPU is produced by a 16-nanometer process. TDP - 70 W. The processor has a built-in graphics core with support for DX11, details about which are not available.

As you can see, in fact KX-U6780A cannot catch up even with Core i3-7100. The performance of the Chinese processor does not even reach the Pentium G5600. Though it's fresher than Core i3-7100, but still it's only a dual-core processor. In some applications the performance of the KX-U6780A processor is catastrophically low.

As for the integrated GPU, it is very weak. In Dota 2, on the lowest graphics quality settings in Full HD, the KX-U6780A processor without a discrete graphics card only provides 17 fps, while the Core i5-7400 with its UHD 630 - 85 fps.


Chinese CPU does not shine and energy efficiency, which is quite expected, given the technological process. All its competitors consume about half the energy.

At the moment Zhaoxin processors are difficult to compare with the most modern AMD and Intel CPUs, because KX-U6780A performs at the level of budget Pentium and Athlon. The pace of development of Chinese technologies is sometimes striking. Probably, in three or four years everything will change cardinally.
