Sandra is a software collection of synthetic benchmarks that will give us a basic idea as to what a system is capable of. It should be noted that SiSoft numbers change depending on what hardware is being tested.  These were recorded using Sandra Professional Version 31.115.2021.12

AIDA64 Extreme Edition is a streamlined diagnostic and benchmarking software package designed to assist with overclocking and general system tuning.  The package also contains modules to assess the performance of the processor, system memory, and disk drives in addition to normal stuff like stress testing and troubleshooting. 

Unigine is a synthetic benchmark much like 3DMark Vantage, but supports the newest of DirectX 11 technologies. The benchmark comes with lots of heavy tessellation and soft shadows to work the more flexible shaders found on DirectX 11 graphic cards. This makes this benchmark ideal for seeing exactly what a best case scenario might look like for a DirectX 11 capable GPU.

SYSmark 25 is an application-based benchmark that reflects usage patterns of business users in the areas of Productivity, Creativity and Responsiveness. The new Productivity Scenario has updated workloads and applications geared towards office centric user activities. The new Creativity Scenario features updated workloads and applications geared toward media-centric user activities. The new Responsiveness Scenario models ‘pain points’ in the user experience. These common activities that include: application launches, file launches, web browsing with multiple tabs, multi-tasking, and background application installation.

PCMark 10 is an overall system benchmark to measure and compare PC performance using real-world tasks and applications. Similar to 3DMark this new version tests the entire system as a whole using applications that reflect typical PC use in the home and at the office.  This approach ensures that PCMark measures the things that matter, highlighting performance differences that will be apparent to end users and consumers.

As expected, we are seeing higher performance from the Viper Xtreme 5 parts given the higher clock speed and better overall timings.  What I find interesting is how flat the performance curves are when it comes to the real world benchmarks such as BAPCo SYSmark and PCMark 10.  For these tests memory plays a smaller role but does show that memory selection does have a profound impact on performance when pared with the right processor.
