In a few of the benchmarks, we also compared it to the AMD 1p/96c Genoa-X system.
Testing Methodology
For this test, we were granted remote access to the Dell Precision 7875 system, located in Dell’s Customer Solutions Center (CSC) lab, thanks to Bharat Patel at Dell. Our connections included the system’s built-in Remote Desktop Protocol (RDP) and a commercial desktop capture application typically used for low-latency game streaming.
Both methods introduce some performance overhead, affecting both CPU and GPU workloads. Specifically, we observed a 3-5 percent drop in performance on CPU-bound tasks and a 5-15 percent drop in GPU-bound jobs. These metrics were determined by comparing results from Dell’s internal tests with our own experiences.
While this setup could be better and does present some challenges for accurate benchmarking, it’s worth noting that the new AMD Threadripper and Dell’s platform still outperformed our in-lab tests. This speaks volumes to their capabilities even under suboptimal testing conditions.
SPECviewperf 2020
Our first test is SPECviewperf 2020, the worldwide standard for measuring graphics performance of professional applications under the OpenGL and Direct X application programming interfaces. The viewsets (or benchmarks) represent graphics content and behavior from actual applications without having to install the applications themselves. The newest version of this benchmark went through significant updates late last year, including new viewsets taken from traces of the latest versions of 3ds Max, Catia, Maya, and Solidworks applications. In addition, they added support within all viewsets for both 2K and 4K resolution displays.
| SPECviewperf2020 Viewsets (Higher is better) | Precision 7875 (AMD 7995WX (96 cores) 2x NVIDIA RTX 6000 Ada) | Transport HX FT65T-B8050 (AMD Genoa-X 9684X, NVIDIA A6000) | Dell Precision 7960 (Xeon w9-3495X, RTX 6000 Ada) |
| 3dsmax-07 | 210.68 | 137.15 | 218.62 |
| Catia-06 | 139.01 | 101.31 | 114.68 |
| Creo-03 | 193.67 | 141.58 | 128.74 |
| Energy-03 | 80.59 | 43.1 | 84.46 |
| Maya-06 | 490.64 | 341.36 | 424.08 |
| Medical-03 | 75.52 | 68.33 | 74.16 |
| Snx-04 | 904.24 | n/a | 932.85 |
| Sw-05 | 288.44 | 168.18 | 299.69 |
In the SPECviewperf2020 benchmarks, the Precision 7975 demonstrates impressive performance across various viewsets, making it a compelling choice for various professional applications. Equipped with an AMD 7995WX (96 cores), dual NVIDIA RTX 6000 Ada GPUs, and 512GB DDR5 RAM, the system particularly excels in the Maya-06 and Snx-04 tests, scoring 490.64 and 904.24, respectively. These scores show that the 7875 outperformed the Transport HX FT65T-B8050 and indicated a strong capability for 3D rendering and simulation tasks. However, it’s worth noting that the Precision 7975 lags slightly behind the Dell Precision 7960 in the 3dsmax-07 and Sw-05 tests. Nonetheless, the Precision 7975 offers a balanced, high-performance package suitable for users who require substantial computational and graphical horsepower.
SPECworkstation 3
SPECworkstation3 specializes in benchmarks designed for testing all critical aspects of workstation performance; it uses over 30 workloads to test CPU, graphics, I/O, and memory bandwidth. The workloads fall into broader categories such as Media and Entertainment, Financial Services, Product Development, Energy, Life Sciences, and General Operations. We will list the broad-category results for each instead of the individual workloads. The results are an average of all the individual workloads in each category.
| SPECworkstation 3 (Higher is better) | Precision 7875 (AMD 7995WX (96 cores) 2x NVIDIA RTX 6000 Ada) | Transport HX FT65T-B8050 (AMD Genoa-X 9684X, NVIDIA A6000) |
| Media and Entertainment | 7.78 | 7.45 |
| Product Development | DNF | DNF |
| Life Sciences | DNF | 14.35 |
| Financial Services | 29.88 | 25.45 |
| Energy | 16.88 | 20.97 |
| General Operations | 1.98 | 2.64 |
| GPU Compute | 8.66 | 7.4 |
In the SPECworkstation 3 benchmarks, the Precision 7875 shows solid performance, particularly excelling in the Financial Services and GPU Compute categories with scores of 29.88 and 8.66, respectively. These results highlight the machine’s capabilities in compute-intensive tasks such as financial modeling and parallel computing. Media and Entertainment narrowly outperformed the Transport HX FT65T-B8050, scoring 7.78 versus 7.45, indicating strong performance in video editing and 3D rendering tasks. However, Precision 7875 gave us a DNF in the Product Development and Life Sciences categories, which sometimes happens for various reasons. The system also lagged in the Energy and General Operations categories compared to the Transport HX.
Blender OptiX
Blender is an open-source 3D modeling application. This benchmark was run using the Blender Benchmark utility. The score is samples per minute, with higher being better.
| Blender OptiX (Samples per minute; Higher is better) | Precision 7875 (AMD 7995WX (96 cores) 2x NVIDIA RTX 6000 Ada) | TYAN Transport HX FT65T-B8050 (AMD Genoa-X 9684X, NVIDIA A6000) | Dell Precision 7960 (Xeon w9-3495X, RTX 6000 Ada) |
| Monster | 6,745 | 2,875 | 6,709 |
| Junkshop | 3,186 | 1,714 | 3,165 |
| Classroom | 3,135 | 1,490 | 3,176 |
In Blender OptiX, the Precision 7875 puts on an impressive display, decisively outpacing the TYAN Transport HX FT65T-B8050 across all tested scenarios due to its dual RTX 6000 Ada GPUs. With scores like 6,745 samples per minute in the Monster test and 3,186 in the Junkshop test, the Precision 7875 showcases its exceptional performance in 3D rendering tasks. Notably, it also slightly edges out its sibling, the Dell Precision 7960, in the Monster and Junkshop tests. The only scene where the 7960 pulls ahead marginally is in the Classroom test, scoring 3,176 samples per minute against the 7875’s 3,135. This could be within the margin of error but might also indicate slight variations in workload handling.
Luxmark
Another 3D benchmark we will look at is LuxMark, an OpenCL GPU benchmarking utility.
| Luxmark (Higher is better) | Precision 7875 (AMD 7995WX (96 cores) 2x NVIDIA RTX 6000 Ada) | TYAN Transport HX FT65T-B8050 (AMD Genoa-X 9684X, NVIDIA A6000) | Dell Precision 7960 (Xeon w9-3495X, RTX 6000 Ada) |
| Hallbench | 63,496 | 20,904 | 31,731 |
| Food | 28,445 | 7,927 | 13,471 |
In the Hallbench scenario, the 7875 almost doubles the score of the Precision 7960 and triples that of the TYAN Transport, registering 63,496 points, similarly, in the Food test. This is undoubtedly due to the dual RTX 6000 Ada GPUs inside the Precision 7875 compared to the 7960’s.
OctaneBench
Next, we look at OctaneBench, a benchmarking utility for OctaneRender, another 3D renderer with RTX support similar to V-Ray.
As you can see below, the performance was similar to that of the Luxmark bench, often doubling the scores of the other Precision workstation due to its GPU configuration. Nonetheless, it was an impressive performance by the Precision 7875.
| OctaneBench (Score, higher is better) | Kernel | Precision 7875 (AMD 7995WX (96 cores) 2x NVIDIA RTX 6000 Ada) | TYAN Transport HX FT65T-B8050 (AMD Genoa-X 9684X, NVIDIA A6000) | Dell Precision 7960 (Xeon w9-3495X, RTX 6000 Ada) |

| Box | Path tracing | 269.92 | 76.12 | 130.36 |
Blackmagic RAW Speed Test
We have also started running Blackmagic’s RAW speed test, which tests video playback performance. Additionally, this test is more of a hybrid test pooling both CPU and GPU in a Real-World scenario for RAW decoding.
| Blackmagic RAW Speed Test (Higher is better) | Precision 7875 (AMD 7995WX (96 cores) 2x NVIDIA RTX 6000 Ada) | TYAN Transport HX FT65T-B8050 (AMD Genoa-X 9684X, NVIDIA A6000) | Dell Precision 7960 (Xeon w9-3495X, RTX 6000 Ada) |
