SiSoftware Sandra and AIDA64
SiSoftware Sandra
We are now testing in the popular SiSoftware Sandra 2021 version. We are testing the CPU arithmetic section. In this graph above we are looking at Dhrystone integer performance in multi-threading. In SiSoftware Sandra 2021 the AMD Ryzen 7 5700G is around 3% faster than the Ryzen 7 3700X, while it is 8% lower than the 5800X. What it seems so far, is that the cache and clock speed differences are making a bigger impact on multi-threading performance, than single-thread performance.
See, this shows that in single-thread performance the Ryzen 7 5700G is very close to the performance of the Ryzen 7 5800X. It’s only 4% slower than the 5800X. The Ryzen 7 5700G is 23% faster than the Ryzen 7 3700X at single-thread performance, which is quite a leap. This is the benefit the newer Zen 3 architecture is making.
Back to multi-threading performance in Whetstone the Ryzen 7 5700G is farther from 5800X performance. It is 3% faster than the Ryzen 7 3700X, and 14% slower than the 5800X.
Then once again in single-thread performance the Ryzen 7 5700G is very close to the Ryzen 7 5800X! it’s 17% faster than the Ryzen 7 3700X and just 5% slower than the 5800X.
AIDA64
We are now going to use AIDA64’s Cache and Memory benchmark to look at RAM memory bandwidth and RAM and cache latencies between both CPUs.
All three CPUs perform about the same on memory read performance, as they are all using the same RAM and memory controller. They average around 50-52GB/s of memory bandwidth on read.
The one thing that does differ is memory write performance, and this is due to the CCD/CCX layout between the CPUs. The 5700G utilizes a different configuration that doesn’t bottleneck the memory write performance as the 3700X and 5800X does. Therefore the 5700G actually has better write performance, about 86% more. This makes a difference in regards to the Vega 8 integrated graphics performance, the higher memory write performance is good for the Radeon Graphics portion of the APU. Otherwise, it doesn’t really make a big difference elsewhere.
