China continues to advance by leaps and bounds, and this time it is thanks to the subsidiary of Ali BabaT-Head, which has expanded information regarding its processor Yitian 710although he has 128 ARMv9 cores and 60,000 million transistors, the most curious of all is that was manufactured by TSMC to a manufacturing process 5nm. Curious, because of this American veto against China which should prevent this kind of thing.
As we now know, these 128 ARMv9 cores, running at 3.20GHz, come with 1 MB of L2 cache per core and 128 MB of L3 cache. Inside the SoC is a controller capable of supporting up to 8 channels of DDR5 @ 4800 MHz memory which achieves a bandwidth of 307.2 GB/sto which are added large NVMe storage capacities or connectivity due to its 96 PCI-Express 5.0 lanes.
The first performance test of this CPU was seen by the benchmark SPECCPU2017and yes, it worked at a lower frequency than 2.75GHz close to 512GB DDR5 RAM @ 4800 MHz (8x 64 GB), and the operating system Anole OS 8.6 (based on Linux) installed on a single SATA III SSD with a capacity of 240 GB.
Although operating below its final frequency, this processor has been 15% faster than AMD EPYC 7773Xsomething impressive considering that this processor uses 64 high-performance cores (AMD Zen3) at base/turbo clock of 2.20/3.50GHz with AMD 3D V-Cache technology to deliver 768 MB L3 cache.
The score obtained was 510 dots (3,984 points per core). The AMD EPYC 7773X reaches 440 dots (6,875 points per core), while a 36-core Intel Xeon Platinum 8351N achieves 266 dots (7.38 points per heart). In the end, ARM cores are less powerful, but can be added in larger quantities while consuming less energy.
Speaking of energy, unfortunately there are a few interesting details missing. on energy consumption of this Yitian 710 CPU, but knowing that it is an ARM CPU, and that it uses the 5nmit is clear that in terms of power per watt consumed it will be light years away from any processor traditional x86.
