Principled Technologies testing showed that a 16th Generation Dell PowerEdge R760 server featuring a Broadcom BCM57508-P2100G NIC delivered all three benefits vs. previous-generation PowerEdge servers
With economic uncertainty, volatile energy prices, and sustainability goals, many organizations are looking for ways to reduce their energy costs and consumption. At the same time, data proliferation and new technologies such as machine learning and artificial intelligence require a large amount of processing power, leading to data centers running at higher power densities—creating more demand on cooling systems.
Principled Technologies (PT) compared the cost, performance, and power efficiency of three generations of Dell PowerEdge servers to show how organizations can potentially save money and accomplish more work by upgrading their older servers.
Using the memtier_benchmark to run 100 percent read workloads against a Redis database, PT measured the operations per second (Ops/s) and throughput (MB/s) of a 14th Generation Dell PowerEdge R740, a 15th Generation Dell PowerEdge R750, and a 16th Generation Dell PowerEdge R760 server. PT calculated the power efficiency (Ops/s/watt) of the devices using the results of their testing, as well as the performance per dollar of each solution (Ops/s/USD).
The PowerEdge R760 server processed 129.5 percent more Ops/s with 24.2 percent better power efficiency than the previous-generation servers, doing over twice as much work with nearly 25 percent better power efficiency than the R740. It also did significantly more work per dollar than the older servers, handling as much as 166.1 percent more Ops/s per dollar. Based on the results of these tests, organizations can improve power efficiency and performance while cutting costs by upgrading to the latest-generation Dell PowerEdge R760 server with Broadcom NICs.
Server | Performance (Ops/s) | Throughput (MB/s) | Power (W) | Perf/W | Perf/USD |
PowerEdge R760 | 64,282,525.28 | 2,533.67 | 832.0 | 77,265.46 | 2,019.9 |
PowerEdge R750 | 49,215,573 | 1,936.3 | 696.1 | 70,698.44 | 1,610.3 |
PowerEdge R740 | 28,000,329.07 | 1,116.47 | 450.3 | 62,179.70 | 758.9 |

Performance results
Classical Deep Learning models performance
The following figure presents the results as a ratio of normalized numbers over the Dell PowerEdge R750xa server with four NVIDIA A100 GPUs. This result provides an easy-to-read comparison of three systems and several benchmarks.
Figure 7: Normalized NVIDIA L40S GPU performance over the PowerEdge R750xa server with four A100 GPUs
The green trendline represents the performance of the Dell PowerEdge R750xa server with four NVIDIA A100 GPUs. With a score of 1.00 for each benchmark value, the results have been divided by themselves to serve as the baseline in green for this comparison. The blue trendline represents the performance of the PowerEdge R760xa server with four NVIDIA L40S GPUs that has been normalized by dividing each benchmark result by the corresponding score achieved by the PowerEdge R750xa server. In most cases, the performance achieved on the PowerEdge R760xa server outshines the results of the PowerEdge R750xa server with NVIDIA A100 GPUs, proving the expected improvements from the NVIDIA L40S GPU. The red trendline has also been normalized over the PowerEdge R750xa server and represents the performance of the PowerEdge R7615 server with two NVIDIA L40S GPUs. It is interesting that the red line almost mimics the blue line. This result suggests that the PowerEdge R7615 server, despite having half the compute resources, still performs comparably well in most cases, showing its efficiency.
Generative AI performance
The latest submission saw the introduction of the new Stable Diffusion XL benchmark. In the context of generative AI, stable diffusion is a text to image model that generates coherent image samples. This result is achieved gradually by refining and spreading out information throughout the generation process. Consider the example of dropping food coloring into a large bucket of water. Initially, only a small, concentrated portion of the water turns color, but gradually the coloring is evenly distributed in the bucket.
The following table shows the excellent performance of the PowerEdge R760xa server with the powerful NVIDIA L40S GPU for the GPT-J and Stable Diffusion XL benchmarks. The PowerEdge R760xa takes the top spot in GPT-J and Stable Diffusion XL when compared to other NVIDIA L40S results.
