Allen Bourgoyne, a director of product advertising at Nvidia, explains why the corporate ended up utilizing the identical GPU powering the A800 server chip initially designed for China as the idea for the brand new A800 40GB Energetic workstation chip.
Whereas Nvidia’s A800 server GPU was initially designed for patrons in China by sidestepping U.S. export restrictions final 12 months, a lately launched workstation model of the chip was all the time meant for a worldwide buyer base, in accordance with an organization consultant.
The product in query is the A800 40GB Energetic, which Nvidia quietly launched final week as a workstation GPU for AI, information science and high-performance computing. The chip is obtainable in North America and different areas not impacted by a brand new wave of U.S. export restrictions introduced final month blocking gross sales of the A800 and different high-end AI chips to China and different international locations.

In an interview with CRN, Allen Bourgoyne, a director of product advertising at Nvidia, stated the corporate launched the A800 40GB Energetic as a result of it wanted a substitute for 2018’s Quadro GV100, which it stopped producing after being one of many final GPUs to make use of Nvidia’s six-year-old Volta structure.
“No matter occurred to China, we’d have needed to construct a follow-on product. We’d’ve wanted to do this, as a result of that product [the GV100] went end-of-life. We wanted a substitute,” he stated.
When the time got here to design the GV100’s successor, the product staff appeared on the GPUs “obtainable to us” that would meet the product necessities outlined by the staff. These necessities included constraints round bodily, electrical, cooling and pricing attributes, and the product additionally needed to ship quick double-precision efficiency, which is essential for HPC functions, in accordance with Bourgoyne.
That is typical of how Nvidia designs its chip-based merchandise.
“It’s mainly product engineering,” Bourgoyne stated.
From the choices obtainable, the product staff determined to make use of “the identical GPU [that] was used within the unique A800 server product,” primarily as a result of A800’s excessive throughput for double-precision computing, which is also called 64-bit floating level or FP64, in accordance with the Nvidia worker.
Nvidia launched the A800 server GPU to clients in China final 12 months as an alternative choice to its highly effective A100 GPU as a result of the latter half had been banned within the nation by U.S. export restrictions.
The corporate designed the A800 to sidestep these restrictions by decreasing the GPU’s chip-to-chip bandwidth, however Nvidia needed to halt gross sales of the A800 and different high-end GPUs to China final month attributable to new U.S. guidelines concentrating on excessive efficiency density capabilities.
To the A800 40GB Energetic’s product staff, nonetheless, it didn’t matter that the A800 began out as a server GPU designed initially for the Chinese language market or that it might be banned from the nation a 12 months later. What was essential was that it was obtainable and it match the staff’s wants.
“It will exist no matter what occurred to China,” Bourgoyne stated.
That is much like how Nvidia tapped the Volta-based V100 server GPU for the GV100 workstation chip.
“For the foreseeable future, we’ll in all probability all the time must leverage information middle components for prime double-precision elements for issues we’d like in desktop. That’s simply the place the expertise is extra essential,” Bourgoyne stated.
How Nvidia Tailored The A800 For A Workstation
To adapt the A800 for a workstation, which is a heavy-duty desktop PC, the product staff wanted to make some modifications from the server design.
One of the crucial essential modifications is the addition of a fan for actively cooling the GPU since a workstation can’t present sufficient cooling for a server chip that’s solely outfitted with a passive cooling resolution, in accordance with Bourgoyne.
As a result of the fan requires energy, that meant the product staff needed to alter the GPU to maintain it throughout the staff’s focused energy funds for the product. These changes included trimming down the GPU’s reminiscence a “little bit” and working the GPU “a little bit slower,” Bourgoyne stated.
The result’s that the A800 40GB Energetic provides “related efficiency” to the A800 server GPU, however it might provide that efficiency in a desktop kind issue moderately than a server, the product marketer added.
How A800 40GB Energetic Compares To Quadro GV100
In comparison with 2018’s Quadro GV100, the A800 40GB Energetic is taken into account an enormous improve, providing 40GB of HBM2 reminiscence versus GV100’s 32GB, a 5,120-bit reminiscence interface versus GV100’s 4,096-bit interface, 1.5 TB/s of reminiscence bandwidth versus GV100’s 870 GB/s, 6,912 CUDA cores versus GV100’s 5,120 CUDA cores and 400 GB/s of NVLink chip-to-chip bandwidth versus GV100’s 200 GB/s.
And whereas the A800 40GB Energetic’s 432 Tensor cores is lower than the GV100’s 640 Tensor cores, the previous is able to hitting greater than 5 instances the height Tensor efficiency at 623.8 teraflops. The GPU additionally offers a single-precision efficiency of 19.5 teraflops and a double-precision efficiency of 9.7 teraflops, that are 31 % will increase over the GV100’s capabilities.
In comparison with the GV100, the A800 40GB Energetic runs 4.2 instances sooner for AI inference with the BERT Giant mannequin, 90 % sooner for AI coaching with the BERT Giant mannequin, 90 % sooner for the GTC benchmark and 70 % sooner for the LAMMPS benchmark, in accordance with inner checks run by Nvidia.
What makes the A800 40GB Energetic an enormous improve is that the GPU is predicated on Nvidia’s Ampere structure, which brings a number of substantial enhancements over Volta, together with a brand new effectivity method for dashing up AI computations known as structural sparsity and the power to separate the GPU into as many as seven GPU cases for working a number of workloads in parallel.
Each GPUs have an influence funds of 240 watts.
A800 40GB Energetic Availability
Nvidia began promoting the A800 40GB Energetic globally by way of channel companions final week, although the latest U.S. export restrictions imply the chip gained’t be obtainable in some international locations, like China.
Based on Nvidia associate PNY Applied sciences, the complete checklist of excluded international locations is as follows:
Afghanistan, Armenia, Azerbaijan, Bahrain, Belarus, Burma, Cambodia, Central African Republic, China, Democratic Republic of Congo, Cuba, Cyprus, Egypt, Eritrea, Georgia, Haiti, Iran, Iraq, Jordan, Kazakhstan, North Korea, Kuwait, Kyrgyzstan, Laos, Lebanon, Libya, Macau, Moldova, Mongolia, Oman, Pakistan, Qatar, Russia, Saudi Arabia, Somalia, South Sudan, Republic of Sudan, Syria, Tajikistan, Turkmenistan, United Arab Emirates, Uzbekistan, Venezuela, Vietnam, Yemen and Zimbabwe.
