Dell EMC PowerEdge R750 Rackmount Server (2U, Dual Socket, Intel Xeon Scalable)

What is the power consumption of the Dell R750?

The Dell PowerEdge R750 supports flexible Power Supply Unit (PSU) configurations ranging from 800W 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 R750 support liquid cooling?

Yes, the Dell PowerEdge R750 supports Direct Liquid Cooling (DLC) options, making it ideal for high-performance computing (HPC) environments where thermal management is critical. DLC allows for more efficient heat dissipation compared to traditional air cooling, enabling higher sustained CPU frequencies and reduced fan noise. This feature is particularly valuable for AI/ML training workloads, scientific computing, and other compute-intensive applications.

Why choose a 2U rackmount server?

2U rackmount servers like the Dell PowerEdge R750 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 R750 delivers dual-socket performance in a compact 2U form factor, making it ideal for 2U rackmount server deployments where space efficiency is paramount.

Intel vs AMD: Should I choose the R750 or R6515?

The Dell PowerEdge R750 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 R750 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 R750 the replacement for the R740?

Yes, the Dell PowerEdge R750 is the direct successor to the popular Dell EMC PowerEdge R740 (14th Generation). The R750 offers significant improvements including 3rd Generation Intel Xeon Scalable processors (Ice Lake) with improved IPC (Instructions Per Cycle) performance, PCIe Gen 4 support (vs PCIe Gen 3 in the R740), and enhanced NVMe support with hardware RAID via the PERC H755N controller. The R750 also features BOSS-S2 boot storage and improved memory bandwidth, making it the ideal upgrade path for R740 customers.
