SPECviewperf® 2020 GiB notes

SPECviewperf reports system memory as gigabytes (GB), even though the actual memory capacity measured and required is in gibibytes (GiB). The use of the term gigabytes is because the term gibibyte is not in broad use and may be confusing. System memory capacity is typically based on the physical memory modules present, which are reported in decimal (GB) despite their internal structure being in binary (GiB). This creates some complexity in virtualization configurations, which may specify and allocate memory to a child OS from the shared pool using decimal (GB). One gigabyte is slightly less than one gibibyte, thus a virtualized workstation may be allocated sufficient gigabytes of memory but fail to meet the minimum required memory to run SPECviewperf. Therefore, for virtualized configurations, memory should be allocated to the child OS sufficient to meet or exceed the minimum memory capacity in binary, where one gibibyte is equal to 1024 to the third power. A few examples are provided below for convenience:

Beyond the minimum requirements, the SPECgpc group recommends that SPECviewperf 2020 be run on a graphics card with at least 2 GB of graphics memory.
