Dell PowerEdge R760 Server performance
The Dell PowerEdge R760 server has the following configuration:
- Two Intel Xeon Gold 6430 processors (32 cores/64 threads each, 1.9 GHz base frequency, 3.4 GHz Turbo, 60 MB cache, 270 W TDP)
- 1 TB of DDR5 memory
- Microsoft Windows Server 2019
- NVIDIA A2 or T4 graphics accelerator (for GPU tests)
Like most 2U rack servers with two processors, the PowerEdge R760 has an almost endless number of options (see the Dell website). As mentioned, in this review we will focus on CPU and GPU performance, as we are dedicating a separate review to storage performance.
Our configuration is not the maximum for this platform; it can be equipped with two 56-core processors and 8 TB of RAM. In total, there are several dozen processor options: Xeon Silver, Gold, Platinum and Max class processors are available.
To demonstrate the versatility of configurations available in the PowerEdge R660 and R760 series, we will compare them.
R660 which had the following configuration:
2 x Intel Xeon Platinum 8452Y processors
512 GB DDR5
The Xeon Platinum 8452Y is a 36-core processor, but it has lower base and turbo frequencies (2.0 GHz and 3.2 GHz). In terms of performance, it shouldn't be too different from the Xeon Gold 6430 in our PowerEdge R760, but there may be other reasons for moving to the Platinum chips. (The MSRP of the Platinum 8452Y is almost double that of the Gold 6430).
HWBOT x265
The HWBOT x265 benchmark from hwbot.org measures system performance when rendering 1080P or 4K video using the x265/HEVC codec. It is designed with modern instruction sets in mind and optimized for multithreading for competitive benchmarking. The difference between the two "head-on" servers is small.

y-cruncher
y-cruncher is a multi-threaded and scalable program that can calculate Pi and other mathematical constants up to trillions of digits. Since its launch in 2009, it has become a popular performance and stress testing tool among hardware enthusiasts and hobbyists. Here again we see that the Xeon Gold chips in the PowerEdge R760 have a slight performance advantage.

The UL Procyon AI Inference benchmark suite tests the performance of various artificial intelligence systems using modern neural networks. Tests are performed only on the central processor. Below are the average values of the calculation execution time; the overall result is in the last line. We ran this test only on the PowerEdge R760.

Conclusion
Dell's PowerEdge R760 line is highly versatile, featuring configurations for mixed workloads, VDI, databases, and general purpose. We already raved about the 1U PowerEdge R660, so we had equally high expectations for the 2U PowerEdge R760, and they lived up to it.
The additional height (+1U) gives the PowerEdge R760 more options for expansion and data storage than the R660, which is logical. Otherwise, both servers have the same processors and memory. Fourth-generation Intel Xeon chips provide up to 56 cores per socket, allowing the PowerEdge R760 to support up to 112 cores and 224 threads, as well as up to 8 TB of RAM. And if you're worried about system overheating (or have already invested in a liquid cooling system), the R760 supports direct liquid cooling (DLC) in some configurations.
The extra height allows the R760 to fit double-width GPUs (although there's also a Dell PowerEdge R760xa model with very high component density, including graphics), so this server really can be configured for almost any workload. On the storage front, we like that this server can be configured with an E3.S backplane to install Gen5 SSDs.
We still like the serviceability of Dell servers and the intuitive remote management of iDRAC, which even has built-in service request tracking.
