FP32 single core comparison against x86, reporting number of times faster or slower than the baseline SG2042
Source publication
The Sophon SG2042 is the world's first commodity 64-core RISC-V CPU for high performance workloads and an important question is whether the SG2042 has the potential to encourage the HPC community to embrace RISC-V. In this paper we undertaking a performance exploration of the SG2042 against existing RISC-V hardware and high performance x86 CPUs in...

... AMD Rome and Intel Icelake CPUs tend to outperform the Intel Broadwell, which is understandable given that the Broadwell is the older of the three. Figure 5 reports results from the same experiment using FP32 and it can be seen that the AMD Rome CPU is fairly lacklustre when executing at single precision compared to double, whereas the Intel processors on average perform just as well, and indeed the Sandybridge outperforms the C920 on average in each class when using FP32. However, the average bars in Figure 5 do not provide a complete picture. ...

... 5 reports results from the same experiment using FP32 and it can be seen that the AMD Rome CPU is fairly lacklustre when executing at single precision compared to double, whereas the Intel processors on average perform just as well, and indeed the Sandybridge outperforms the C920 on average in each class when using FP32. However, the average bars in Figure 5 do not provide a complete picture. As described in Section 3.2, the C920 only supports vectorisation for FP32 and indeed it can be seen from the whiskers in Fig- ures 5 and 4 that the maximum times faster is less for many benchmarks classes at FP32 than FP64. ...
