Dell EMC PowerEdge R650XS technical overview
The R650XS platform includes:
What is the power consumption of the Dell R650XS?
The Dell PowerEdge R650XS supports flexible Power Supply Unit (PSU) configurations ranging from 600W to 1400W with Platinum or Titanium efficiency ratings. The Titanium efficiency PSUs deliver up to 96% efficiency at 50% load, significantly reducing operational costs in data centre environments. Power consumption varies based on CPU configuration, memory density, and storage options, but typical configurations consume between 200W (idle) and 800W (full load) depending on workload intensity.
Does the Dell R650XS support liquid cooling?
No, the Dell PowerEdge R650XS uses air cooling only with up to 7 fans for efficient thermal management. This cost-effective cooling solution is suitable for the mid-sized workloads the R650XS is designed to handle. For high-performance computing environments requiring liquid cooling, consider the standard R650 model.
Why choose a 1U rackmount server?
1U rackmount servers like the Dell PowerEdge R650XS offer superior density compared to 2U or tower servers, allowing you to maximise compute power per rack unit. This is essential for data centres with limited space or high-density virtualisation environments. The R650XS delivers dual-socket performance in a compact 1U form factor, making it ideal for 1U rackmount server deployments where space efficiency is paramount.
Intel vs AMD: Should I choose the R650XS or R6515?
The Dell PowerEdge R650XS uses Intel Xeon Scalable processors (Ice Lake), while the R6515 uses AMD EPYC processors. For maximum single-thread performance and Intel-optimised software ecosystems (such as VMware vSphere, Microsoft SQL Server, and many enterprise applications), the R650XS remains the industry standard. If you require higher core counts per dollar and are running workloads optimised for AMD architecture, consider the Dell PowerEdge R6515 with AMD EPYC processors. Both servers support PCIe Gen 4 and offer excellent performance for their respective use cases.
Is the Dell R650XS the replacement for the R640?
Yes, the Dell PowerEdge R650XS is the direct successor to the popular Dell EMC PowerEdge R640 (14th Generation). The R650XS offers significant improvements including 50% higher memory bandwidth, PCIe Gen 4 support (vs PCIe Gen 3 in the R640), and support for 3rd Generation Intel Xeon Scalable processors (Ice Lake) with improved IPC (Instructions Per Cycle) performance. The R650XS also features enhanced NVMe support with hardware RAID via the PERC H755N controller, making it the ideal upgrade path for R640 customers.
