The first benchmarks of China’s Domestic Zhaoxin KH-4000 CPU have appeared online and display overall performance near to AMD’s to start with-gen Zen CPUs.
1st Gen AMD Zen Efficiency In-Sight By China’s Domestic Zhaoxin KH-4000 16 Core CPU
The Zhaoxin CPUs are developed domestically for the Chinese customer and server segment. We have presently found the customer-stage chips in action but this time, general performance of the server-tier KH-4000 CPUs has been showcased. The functionality was measured inside the SPEC CPU2006 workload and focuses purely on the one-threaded performance. But right before we get to the tests, let’s take a quick glance at the specs.
Zhaoxin’s KH-4000 CPU, after yet again, is concentrated on the server sector and will be centered on a 16nm course of action node. The certain chip that has been tested, rocks 16 cores and 16 threads with a clock velocity of two.7 GHz. The chip capabilities a DDR4 memory controller and comes with PCIe Gen three. information transfer protocol. The CPUs can go up to 32 cores and 64 cores (on a dual-socket system). A endeavor supervisor screenshot displays that the chip also homes 32 MB of L3 cache and four MB of L2 cache. The TDP figure is not offered but it should really be north of 100W considering we are speaking sixteen cores on an older 16nm course of action node.
As for overall performance, the SPEC CPU2006 Integer outcomes demonstrate that the Zhaoxin KH-4000 sixteen Main CPU was typically on par with the AMD EPYC 7601 (benefits from Anandtech). This usually means that China’s CPU industry is now perhaps on par with the initially-era Zen CPUs. The future iterations of Zen up until Zen three do force the overall performance envelope way larger but this achievement for Zhaoxin is nevertheless a big offer. We have earlier seen buyer-tier chips on par with an Intel Core i5-7600K about below.
In the results underneath, you can see that the Zhaoxin KH-4000 is operating at a reduce frequency of two.seven GHz versus the 3.two GHz of AMD’s EPYC Naples chip:
There’s nonetheless a extensive way to go for China’s domestic CPU marketplace and Zhaoxin in their x86 ventures but this does give an substitute to the domestic server sector and a less costly one particular also. The producer also has 7nm chips coming in the long run with DDR5 and PCIe 4. assist so maintain wanting forward to far more data.
