Introduction
On March 15th, AMD officially announced their new EPYC 7003 Series of server processors. As you might expect, a flood of new benchmark results is starting to appear. One very interesting one is a new AMD EPYC 7763 TPC-H result for an HPE Proliant DL345 Gen10 Plus server. This server has one 64C/128T AMD EPYC 7763 processor, and the result is very impressive.
New AMD EPYC 7763 TPC-H Result
The HPE Proliant DL345 Gen10 Plus is a new model one-socket server that will be available on April 19th, 2021. The official TPC-H result is 1,346,932 QphH on a 3000 scale factor data warehouse. The scale factor means that the database was 3,000GB.
This server has a 64C/128T AMD EPYC 7763 “Milan” processor, 2TB of RAM, and twelve NVMe drives. The system is running SQL Server 2019 Enterprise Edition on Red Hat Linux 8.
Previous AMD EPYC 7742 TPC-H Result
A little over a year ago, HPE submitted an official TPC-H result for a one-socket HP Proliant DL325 Gen10 Plus system. The score for that system is 1,057,103 QphH on a 3000 scale factor data warehouse.
This server has a 64C/128T AMD EPYC 7742 “Rome” processor, 2TB of RAM, and twelve NVMe drives. The system is also running SQL Server 2019 Enterprise Edition on Red Hat Linux 8. This older system is essentially identical to the new Proliant DL345 Gen10 Plus except for the new processor.
Comparative TPC-H Results
I think these are two very valuable TPC-H results for comparision purposes. First, they are on the same 3000 scale factor database, which is critical. Second, they are running on the same operating system and version of SQL Server. Finally, both systems have the same amount of RAM and the same exact storage configuration.
The only difference is the processor in each system. Both systems use the “flagship” 64C/128T processor from the respective AMD EPYC 7003 and AMD EPYC 7002 Families.
| Processor | TPC-H Score | Cores | Score/Core |
| AMD EPYC 7763 | 1,346,932 | 64 | 21,045.81 |
| AMD EPYC 7742 | 1,057,103 | 64 | 16,517.23 |
The newer AMD EPYC 7763 processor has a 27.4% higher TPC-H score than the previous AMD EPYC 7742 processor!
Comparative Processor Specifications
Here are the respective specifications for these two processors. The Zen 3 Milan has an average 19% IPC boost over the Zen 2 Rome. We also have higher clock speeds and a higher cTDP rating. All of this contributes to the 27.4% higher performance in TPC-H.
| Processor | Base Clock | Boost Clock | L3 Cache | TDP |
| AMD EPYC 7763 | 2.45 GHz | 3.50 GHz | 256MB | 280W |
| AMD EPYC 7742 | 2.25 GHz | 3.40 GHz | 256MB | 225W |
Final Words
This TPC-H result reinforces my earlier estimates of a 25% performance improvement for Milan compared to Rome. I have more details about that in this post.
