Dell PowerEdge R770/670 Server Achieves Up to 67% Performance Gain

The Dell PowerEdge R770/R670 server achieves up to 67% performance gains with Intel® 6th Gen P-Core processors.

Review
The Dell PowerEdge R770/R670 is a two-socket rack server designed for high-performance computing with optimal energy efficiency and balanced performance to enhance your data center productivity. It combines advanced computing power with innovative design efficiencies to maximize rack space and minimize power consumption. The R770/670 is ideal for workloads such as virtualization, cloud applications, large-scale analytics, and distributed data intelligence.

Specifically designed for enterprise and scale-out infrastructures, the PowerEdge R770/670 offers standardization that easily integrates into existing environments powered by dual Intel Xeon 6 processors with E and P cores. The latest PowerEdge R770/670 model offers dual 6th Generation Intel Xeon Scalable processors with up to 86 P cores per processor.
Main conclusions
The PowerEdge R770/670 (2-socket) with the latest 86-core 6th Gen Intel Xeon SP processor delivers up to 45% more compute performance than the previous generation R760 with 64-core 5th Gen Intel Xeon SP processor and up to 67% more performance than the R760 with 56-core 4th Gen Intel Xeon SP processor.
The PowerEdge R770/670 with the latest 86-core 6th Gen Intel Xeon SP processor delivers up to 20% more memory bandwidth than the previous generation R760 with 64-core 5th Gen Intel Xeon SP processor, and up to 36% more memory bandwidth than the R760 with 56-core 4th Gen Intel Xeon SP processor.
The PowerEdge R770/670 with the latest 86-core 6th Gen Intel Xeon SP processor delivers 62% greater HPL performance than the previous generation R760 with 64-core 5th Gen Intel Xeon SP processor, and 96% greater HPL performance than the R760 with 56-core 4th Gen Intel Xeon SP processor.
Benchmarking Overview: SpecCPU, HPL, Stream
We ran three benchmarks—SPEC CPU, High-Performance Linpack (HPL), and STREAM—to compare the performance of the 5th Generation Intel Xeon R760 and 6th Generation R770 processors. We present the SPEC CPU INT Rate Base metric, which focuses on integer throughput, providing a metric called SPECrate. This metric indicates how many integer tasks a system can complete in a given amount of time. HPL is measured in Gflops, or floating-point operations per second, which assesses overall computing power. STREAM measures memory throughput in MB/s.

Testing was conducted at Dell Solutions Performance Analysis (SPA) labs in February 2025. The following generational comparisons represent common Intel processor configurations for R770 and R760 customers:
