Performance & Acceleration:
- R760xa: Clearly takes the lead in GPU-centric tasks. Supporting up to 8 double-width GPUs (or 3 SXM5 modules + 1 PCIe GPU) with optional Direct Liquid Cooling allows it to handle the most intensive AI/ML models and simulations that demand maximum GPU density and sustained performance without thermal throttling. Its native support for 5th Gen Intel Xeon (Emerald Rapids) also provides a potential CPU performance edge.
- DL380 Gen10 Plus: Delivers excellent CPU performance for mainstream enterprise applications and supports up to 4 double-width GPUs effectively. This makes it suitable for AI inferencing, VDI with GPU acceleration, and workloads needing moderate GPU power alongside strong general compute. Its mature platform is highly optimized for virtualization efficiency.
Flexibility & Storage:
- DL380 Gen10 Plus: Offers superior front-bay configuration flexibility (SFF or LFF, multiple density options), making it adaptable to diverse storage needs without sacrificing core compute resources. It remains a top choice for storage-heavy virtualized environments or traditional databases.
- R760xa: While offering good NVMe capabilities (front, rear, PCIe Gen5), its front bay configuration is typically less varied than the DL380, prioritizing the internal space for GPUs and their cooling infrastructure. Its storage strength lies in high-speed, low-latency NVMe for GPU-adjacent data.
Cooling & Efficiency:
- R760xa: Its raison d’être is cooling dense accelerators. MultiVector Cooling+ dynamically adjusts based on component telemetry, and the optional DLC is a game-changer for exhausting the immense heat from 8 high-end GPUs, significantly improving performance stability and power efficiency under max load.
- DL380 Gen10 Plus: Features excellent thermal management (Sea of Sensors) and power capping for general server workloads and configurations up to 4 GPUs. It efficiently handles demanding air-cooled scenarios but doesn’t target the extreme cooling envelope of the R760xa.
Management & Security:
- Both offer industry-leading, integrated lights-out management (iDRAC9 vs iLO 6) with robust security features (Silicon Root of Trust, Secure Boot, etc.) and cloud-based analytics/monitoring (CloudIQ vs GreenLake). The choice often comes down to existing ecosystem preference or specific feature nuances.
Choosing the Right Tool:
Choose the Dell PowerEdge R760xa if:
- Your primary workloads are AI training, large-scale ML inference, complex HPC simulations, or rendering.
- You require maximum GPU density (5+ GPUs) in a 2U form factor.
- Sustained high-performance computing under extreme thermal loads is critical (consider DLC).
- You prioritize the latest CPU technology (5th Gen Intel Xeon) and PCIe Gen5 bandwidth for accelerators/NVMe.
Choose the HPE ProLiant DL380 Gen10 Plus if:
- You need a versatile, proven workhorse for virtualization, enterprise databases (SQL, Oracle), ERP/CRM, or general business applications.
- Your workloads require strong CPU performance and moderate GPU acceleration (1-4 GPUs).
- Front-bay storage flexibility (mix of SFF/LFF, higher drive counts) is a significant requirement.
- You value the maturity and widespread deployment success of the Gen10 Plus platform.
Conclusion:
Both the Dell PowerEdge R760xa and HPE ProLiant DL380 Gen10 Plus are exceptional 2U servers. The R760xa stands alone in its class for pushing the boundaries of GPU density and acceleration-focused performance, making it the undisputed choice for the most demanding AI and technical computing tasks. The DL380 Gen10 Plus remains a paragon of versatility and proven enterprise reliability, excelling as a balanced platform for a wide spectrum of mainstream critical workloads. The optimal decision hinges entirely on whether your priority lies at the bleeding edge of accelerated computing or in the robust, flexible heart of the enterprise data center. Carefully evaluate your core workloads, performance targets, and infrastructure strategy to make the right investment.
