Dell Precision T7920 Workstation Test System
Here is a list of how our Dell Precision T7920 Workstation is equipped:
- Processor: Dual Intel Xeon Platinum 8260 2.4GHz, 3.9GHz Turbo, 24C/48 Threads
- Memory: 96GB 12x8GB DDR4 2933MHz RDIMM ECC
- Graphics Card: Nvidia Quadro RTX 8000, 48GB, 4DP, VirtualLink
- OS Boot: Dell Ultra-Speed Drive Duo PCIe SSD x8 Card with 1x M.2 512GB PCIe NVMe Class 50 Solid State Drive
- Internal RAID Controller: MegaRAID SAS 9460-16i 12Gb/s PCIe SATA/SAS HW RAID controller (4GB cache)
- HDDs in Raid 10: 4x 3.5″ 4TB 7200rpm SATA Enterprise Hard Drive
- Thunderbolt 3: PCIe card – 2 Type C Ports, 1 DP
- OS: Windows 10 Pro for Workstations
Realistically, most of our users will order a dual Intel Xeon Platinum 8260 configuration with 12x 32GB DDR4 DIMMs or more. Our memory channels are full using 1 DIMM per channel in this configuration but our capacity is relatively low. This system can scale well beyond 1TB of memory, something that the high-end desktop offerings simply cannot match.
The CPU we will be using is dual Intel Xeon Platinum 8260 2.4GHz (24 cores/ 48 threads.) These two processors give the system a full 48 cores/ 96 threads.
The Intel Xeon Platinum 8260 is a very capable CPU, the base speed is 2.4GHz but can Turbo up to 3.9GHz. It also has the full feature set support that Intel offers in this generation including dual-port FMA AVX-512 and DL Boost.
Let us continue with performance testing.
Dell Precision T7920 Performance Testing
As we move along with the motherboard testing we felt it was time to clean up our database and results in graphs, some new benchmarks we have not run before but will be adding them in, or newly updated benchmarks render past versions obsolete so we must start over with that benchmark. We also note that at this time the Dell Precision T7920 Workstation is one of the first current dual-processor Xeon Scalable workstations we have reviewed, as a result, we do not have comparison benchmark numbers at this time for other systems in Windows. You can see that we have tested the Platinum 8260 and 8260L previously on STH in Linux, and have a large dataset for Xeon Scalable Linux results. For this review, we will chart our Windows benchmark results so that we can add others later.
We also ran the NVIDIA Quadro RTX 8000 in a separate review so that we could look at the RTX 8000 and compare it to the large number of GPUs we have reviewed to date. System benchmarks with the RTX 8000 were run with the Dell Precision T7920 workstation and shown in this review. If you want to get a sense of relative performance for GPU options, check the Quadro RTX 8000 piece.
Dell Precision T7920 Workstation CrystalDiskMark
CrystalDiskMark is a well-known benchmark to test your HDD or SSD’s.
Here the SK.hynix PC400 NVMe SSD performed very well. At the same time, large manufacturers source SSDs from multiple vendors to ensure supply chain continuity so Dell can offer different 512GB drives if needed in the future.
Dell Precision T7920 Workstation AIDA64 Memory Test
AIDA64 memory bandwidth benchmarks (Memory Read, Memory Write, and Memory Copy) measure the maximum achievable memory data transfer bandwidth.
We have 96GB 12x8GB DDR4 2933MHz RDIMM ECC Low Profile sticks on our Dell Precision T7920 Workstation which boosts memory read speeds a great deal. If you are looking for full memory bandwidth, then you will want 12 DIMM configurations. We also suggest that using higher-capacity DIMMs can be a worthwhile upgrade.
Dell Precision T7920 Workstation Cinebench R15
Here are our Cinebench R15 results:
We ran Cinebench R15 several times, this is the best score we received which reinforces Cinebench does better with CPU’s that have a larger number of cores. Single-core performance on the Intel Xeon Platinum 8260 is very good, multi-core shows high performance.
Dell Precision T7920 Workstation Cinebench R20
Here is the newer Cinebench R20 result:
We have only just started using Cinebench R20, it shows the Intel Xeon Platinum 8260 again shows impressive results.
If you compare to our Linux results, you would use our c-ray 8K results to see similar scaling.
Dell Precision T7920 Workstation Geekbench 4
Geekbench 4 is a popular benchmark so we are running it here.
The Intel Xeon Platinum 8260 generates very good results, but Geekbench is known to struggle at higher core counts and with more than one CPU. That is something we found setting a Geekbench 4 world record earlier this year. Some software will not scale well across multiple CPUs despite the maturity of the architecture.
Next, we are going to look at system performance benchmarks.
