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 known as “undertaking DIGITS” (to not be confused with the Nvidia The Deep Studying GPU Coaching System: DIGITS). The platform provides a collection of recent 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 working massive AI fashions. (Necessary floating level explainer could also be useful right here.)
Because the launch of the G8x line of video playing cards (2006), Nvidia has finished a great job of offering CUDA instruments and libraries accessible throughout all the 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. As a result of price 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 ought to be engaging to builders. For instance, by providing 128GB of reminiscence, the DIGITS system will assist overcome the 24GB limitation on many lower-cost client 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 accessible, the GPU aspect of the GB10 is assumed to supply much less efficiency than the Grace-Blackwell GB200. To be clear; the GB10 shouldn’t be 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 dimension breaks a “GPU reminiscence barrier” when working AI or HPC fashions on GPUs; for example, present market costs for the 80GB Nvidia A100 range 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. By way of energy, Nvidia mentions a typical electrical outlet. There aren’t any particular energy necessities, however the dimension and design might give a couple of clues. First, just like the Mac mini methods, the small dimension (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 flooring, no fan vents or cutouts exist. The back and front of the case appear to have a sponge-like materials that would present air circulate 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 fairly a cool, quiet, and proficient AI desktop system with an optimized reminiscence structure.
As talked about, the system is extremely small. The picture under provides 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 experiences that builders can run as much as 200-billion-parameter massive language fashions to supercharge AI innovation. As well as, utilizing Nvidia ConnectX networking, two Mission DIGITS AI supercomputers will 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 heart infrastructure.

“AI shall be mainstream in each software for each trade. With Mission DIGITS, the Grace Blackwell Superchip involves hundreds of thousands of builders,” stated Jensen Huang, founder and CEO of Nvidia. “Inserting an AI supercomputer on the desks of each information scientist, AI researcher, and scholar empowers them to interact and form the age of AI.”
These methods aren’t supposed for coaching however are designed to run quantized LLMs domestically (cut back the precision dimension 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 degree, however quantization will be elevated to FP8, FP16, or greater for probably higher outcomes relying on the dimensions of the mannequin and the accessible reminiscence. As an illustration, 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 right down to 35GB of reminiscence, however growing to FP32 would require 140GB, which is bigger than the DIGITS system provides.
HPC cluster anybody?
What might not be extensively identified is that the DIGITS shouldn’t be the primary desk-side Nvidia system. In 2024, GPTshop.ai launched a GH200-based desk-side system. HPCwire supplied protection that included HPC benchmarks. Not like the DIGITS undertaking, the GPTshop methods present the total heft of both the GH200 Grace-Hopper Superchip and GB200 Grace-Blackwell Superchip in a desk-side case. The elevated efficiency additionally comes with the next price.
Utilizing the DIGITS Mission methods for desktop HPC may very well be an attention-grabbing strategy. Along with working bigger AI fashions, the built-in CPU-GPU world reminiscence will be very useful to HPC functions. Take into account a latest HPCwire story about CFD software working solely on Intel two Xeon 6 Granite Rapids processors (no GPU). In response to creator 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 frequent PCIe-attached video playing cards. Utilizing a number of playing cards or MPI helps unfold out the appliance, however probably the most enabling think about HPC is all the time extra reminiscence.
In fact, benchmarks are wanted to find out the suitability of the DIGITS Mission absolutely for desktop HPC, however there’s one other chance: “construct a Beowulf cluster of those.” Typically thought-about a little bit of a joke, this phrase could also be a bit extra critical concerning the DIGITS undertaking. In fact, clusters are constructed with servers and (a number of) PCEe-attached GPU playing cards. Nonetheless, a small, reasonably powered, absolutely built-in world reminiscence CPU-GPU may make for a extra balanced and engaging cluster constructing block. And right here is the bonus: they already run Linux and have built-in ConnectX networking.
