On the 2025 CES occasion, Nvidia introduced a brand new $3000 desktop laptop developed in collaboration with MediaTek, which is powered by a brand new cut-down Arm-based Grace CPU and Blackwell GPU Superchip. The brand new system is named “undertaking DIGITS” (to not be confused with the Nvidia The Deep Studying GPU Coaching System: DIGITS). The platform gives a sequence of latest capabilities for each the AI and HPC markets.
Mission DIGITS options the brand new Nvidia GB10 Grace Blackwell Superchip with 20 Arm cores and is designed to supply a “petaflop” (at FP4 precision) of GPU-AI computing efficiency for prototyping, fine-tuning and operating giant AI fashions. (Necessary floating level explainer could also be useful right here.)
For the reason that launch of the G8x line of video playing cards (2006), Nvidia has achieved an excellent job of offering CUDA instruments and libraries out there throughout the whole line of GPUs. The flexibility to make use of a low-cost buyer video card for CUDA improvement has helped create a vibrant ecosystem of functions. Because of the value and shortage of performant GPUs, the DIGITS undertaking ought to allow extra LLM-based software program improvement. Like a low-cost GPU, the flexibility to run, configure, and fine-tune open transformer fashions (e.g., llama) on a desktop needs to be enticing to builders. For instance, by providing 128GB of reminiscence, the DIGITS system will assist overcome the 24GB limitation on many lower-cost shopper video playing cards.
Scant Specs
The brand new GB10 Superchip options an Nvidia Blackwell GPU with latest-generation CUDA cores and fifth-generation Tensor Cores, linked through NVLink-C2C chip-to-chip interconnect to a high-performance Nvidia Grace-like CPU, which incorporates 20 power-efficient Arm cores (ten Arm Cortex-X925 and ten Cortex-A725 CPU cores . Although no specs have been out there, the GPU aspect of the GB10 is assumed to supply much less efficiency than the Grace-Blackwell GB200. To be clear; the GB10 is just not a binned or laser trimmed GB200. The GB200 Superchip has 72 Arm Neoverse V2 cores mixed with two B200 Tensor Core GPUs.

The defining function of the DIGITS system is the 128GB (LPDDR5x) of unified, coherent reminiscence between CPU and GPU. This reminiscence measurement breaks a “GPU reminiscence barrier” when operating AI or HPC fashions on GPUs; as an illustration, present market costs for the 80GB Nvidia A100 differ from $18,000 to $20,000. With unified, coherent reminiscence, PCIe transfers between CPU and GPU are additionally eradicated. The rendering within the picture under signifies that the quantity of reminiscence is mounted and can’t be expanded by the person. The diagram additionally signifies that ConnectX networking (Ethernet?), Wifi, Bluetooth, and USB connections can be found.
The system additionally gives as much as 4TB of NVMe storage. When it comes to energy, Nvidia mentions a normal electrical outlet. There aren’t any particular energy necessities, however the measurement and design might give a number of clues. First, just like the Mac mini methods, the small measurement (see Determine 2) signifies that the quantity of generated warmth should not be that top. Second, based mostly on the photographs from the CES present ground, no fan vents or cutouts exist. The back and front of the case appear to have a sponge-like materials that would present air stream and will function complete system filters. Since warmth design signifies energy and energy signifies efficiency, the DIGITS system might be not a screamer tweaked for max efficiency (and energy utilization), however somewhat a cool, quiet, and proficient AI desktop system with an optimized reminiscence structure.
As talked about, the system is extremely small. The picture under gives some perspective in opposition to a keyboard and monitor (There aren’t any cables proven. In our expertise, a few of these small methods can get pulled off the desktop by the cable weight.)
AI on the desktop
Nvidia reviews that builders can run as much as 200-billion-parameter giant language fashions to supercharge AI innovation. As well as, utilizing Nvidia ConnectX networking, two Mission DIGITS AI supercomputers could be linked to run as much as 405-billion-parameter fashions. With Mission DIGITS, customers can develop and run inference on fashions utilizing their personal desktop system, then seamlessly deploy the fashions on accelerated cloud or information middle infrastructure.

“AI shall be mainstream in each utility for each trade. With Mission DIGITS, the Grace Blackwell Superchip involves hundreds of thousands of builders,” stated Jensen Huang, founder and CEO of Nvidia. “Putting an AI supercomputer on the desks of each information scientist, AI researcher, and pupil empowers them to interact and form the age of AI.”
These methods should not meant for coaching however are designed to run quantized LLMs regionally (scale back the precision measurement of the mannequin weights). The quoted one petaFLOP efficiency quantity from Nvidia is for FP4 precision weights (4 bits, or 16 potential numbers)
Many fashions can run adequately at this stage, however quantization could be elevated to FP8, FP16, or larger for probably higher outcomes relying on the dimensions of the mannequin and the out there reminiscence. As an example, utilizing FP8 precision weights for a Llama-3-70B mannequin requires one byte per parameter or roughly 70GB of reminiscence. Halving the precision to FP4 will reduce that all the way down to 35GB of reminiscence, however growing to FP32 would require 140GB, which is bigger than the DIGITS system gives.
HPC cluster anybody?
What will not be broadly identified is that the DIGITS is just not the primary desk-side Nvidia system. In 2024, GPTshop.ai launched a GH200-based desk-side system. HPCwire offered protection that included HPC benchmarks. Not like the DIGITS undertaking, the GPTshop methods present the complete heft of both the GH200 Grace-Hopper Superchip and GB200 Grace-Blackwell Superchip in a desk-side case. The elevated efficiency additionally comes with a better value.
Utilizing the DIGITS Mission methods for desktop HPC might be an fascinating strategy. Along with operating bigger AI fashions, the built-in CPU-GPU international reminiscence could be very helpful to HPC functions. Take into account a current HPCwire story about CFD utility operating solely on Intel two Xeon 6 Granite Rapids processors (no GPU). In accordance with writer Dr. Moritz Lehmann, the enabling issue for the simulation was the quantity of reminiscence he was in a position to make use of for his simulation.
Similarly, many HPC functions have needed to discover methods to get across the small reminiscence domains of widespread PCIe-attached video playing cards. Utilizing a number of playing cards or MPI helps unfold out the applying, however probably the most enabling think about HPC is at all times extra reminiscence.
After all, benchmarks are wanted to find out the suitability of the DIGITS Mission totally for desktop HPC, however there may be one other risk: “construct a Beowulf cluster of those.” Usually thought of a little bit of a joke, this phrase could also be a bit extra critical concerning the DIGITS undertaking. After all, clusters are constructed with servers and (a number of) PCEe-attached GPU playing cards. Nevertheless, a small, reasonably powered, totally built-in international reminiscence CPU-GPU would possibly make for a extra balanced and enticing cluster constructing block. And right here is the bonus: they already run Linux and have built-in ConnectX networking.
