GUNNIR Shows Liquid-Cooled Dual Intel Arc Pro B70 Workstation With 64GB VRAM

What GUNNIR showed at Intel Connection 2026​

According to VideoCardz, both systems were shown at Intel Connection 2026 in China. The Chinese site IT Home says GUNNIR showed its dual-card liquid-cooled workstation and its mini-workstation in public for the first time at the conference on September 22.

There were two machines:

• The dual-GPU workstation. TechRadar reports that the larger system fits two Arc Pro B70 cards inside a compact enclosure, while liquid cooling handles the heat from the graphics hardware.
• The mini-workstation. VideoCardz says the dual-GPU system uses liquid cooling, while the smaller machine relies on a vapor chamber cooling design.
• The platform. GUNNIR paired the graphics cards with Intel Core Ultra 200HX "Arrow Lake-HX" processors, according to the event coverage.

TechRadar's headline says there's "no AMD version in sight", and that's technically true. Both machines use Intel Core Ultra 200HX Arrow Lake-HX processors, so neither configuration includes an AMD processor or graphics option anywhere in its hardware. But nothing reported says GUNNIR has ruled out an AMD configuration. Intel hosted the event and GUNNIR is one of Intel's GPU partners, so an all-Intel showcase is about as surprising as finding Coca-Cola at a Coca-Cola convention.

Some context of my own, based on general industry knowledge: the Core Ultra 200HX family is Intel's high-performance laptop-class Arrow Lake line. That probably helps explain how GUNNIR kept the chassis small. The coverage does not say which 200HX model GUNNIR used, so I won't guess.

Section summary: GUNNIR showed two Intel-only compact workstations. The larger one has two liquid-cooled B70 cards, and the smaller one uses vapor-chamber cooling. No prices, shipping dates or full specifications were given.

The "64GB" caveat: two GPUs, not one big pool​

Many readers will see "64GB" and picture one giant GPU, so this point matters. Each Arc Pro B70 comes with 32GB of GDDR6 ECC memory, so the dual-card system provides 64GB across the two GPUs. VideoCardz says this memory is not presented to software as one conventional 64GB graphics card, but Intel supports multi-GPU compute through oneAPI for workloads capable of using multiple devices.

In practice:

1. Software has to support multiple GPUs. A model or app that only knows how to use one device will see 32GB, not 64GB.
2. Inference frameworks can split a model across cards. Intel's own Arc Pro B-Series page highlights Linux support for multi-GPU AI. It says multiple GPUs can be combined to run large models that need more than 100GB of VRAM. How well that scales depends on the workload.
3. Bandwidth is per card. Intel's spec sheet lists 608GB/s and a 256-bit memory interface for each B70. That figure doesn't double into one combined number for the workstation.

Why does memory capacity get so much attention? Tom's Hardware explained it when the card launched: both the relatively large VRAM capacity and higher memory bandwidth of this card are important for LLM inference workloads, where being able to fit both models and context in GPU-local memory is critical.

Section summary: 64GB is the total across two separate GPUs. Workloads that can't use more than one device will only see half of it.

The Arc Pro B70 under the hood​

The B70 is the top card in Intel's Arc Pro B-Series. Here are the key per-card figures from Intel's specification page, alongside GUNNIR's own retail version:

The GUNNIR TF figures come from VideoCardz's launch coverage. It reported that the Arc Pro B70 TF is listed 290W board power, and a 2600 MHz clock, and that GUNNIR appears to be targeting workstation and AI deployments with blower-based TF models.

That 290W rating matters. GUNNIR's retail card runs at the top of Intel's 160–290W partner range. If the workstation uses boards tuned the same way, the graphics cards alone could draw close to 600W. GUNNIR hasn't said how its workstation boards are configured or what the whole system draws, so this is a reason to wait for specs, not a measurement. It does explain why the dual-card box needed liquid cooling.

Intel also lists PCIe 5.0 x16, support for four displays, DisplayPort 2.1 up to UHBR 13.5, and hardware AV1, HEVC and H.264 encode and decode. Windows-centric shops will want to know about DirectX 12 Ultimate support, plus oneAPI, OpenVINO and Intel Extension for PyTorch support.

Section summary: The B70 is a 32-core, 32GB card. GUNNIR's own version is clocked higher and rated at the maximum 290W.

Price and positioning: a reference point, not a quote​

Intel launched the B70 on March 25, 2026, alongside its Core Ultra Series 3 commercial platform. GUNNIR was named as a launch partner, and Intel set a $949 suggested starting price for its own branded card. Tom's Hardware reported that Intel positions the B70 against Nvidia's $1,800 RTX Pro 4000 24GB, pointing to larger context windows and better time-to-first-token latency under many concurrent users.

Can you double $949 and call that the workstation's price? No. GUNNIR hasn't announced pricing for either machine, partner cards are priced differently from Intel's own, and the CPU, chassis, cooling loop and power supply all add cost on top.

Software maturity is also a fair concern. StorageReview's headline for its B70 review captured it well: "The Hardware Is Ready, the Stack Needs to Catch Up." Intel's own multi-GPU performance claims were measured on Ubuntu with vLLM containers, so Linux-first AI teams will likely get the most out of a box like this today.

Section summary: $949 is what Intel's card costs, not what this system will cost. Intel pitches the B70 as a cheaper alternative to Nvidia's RTX Pro 4000, but results depend on the software stack.

The smaller pieces: mini-workstation and MXM modules​

GUNNIR also showed MXM-format graphics modules built on Arc Pro B50 and B65 chips. MXM is the compact module format used in systems where a full-size PCIe card won't fit. The coverage didn't give memory, clocks or pricing for these modules. Intel's general specs for the GPU families list the B65 at 20 Xe cores, 608GB/s and 197 INT8 TOPS, and the B50 at 16 Xe cores, 224GB/s and 170 INT8 TOPS. GUNNIR's MXM versions could be configured differently.

Who should care?​

• Small AI teams and developers who want to run local inference on sensitive data without renting cloud GPUs and are comfortable with Linux and multi-GPU frameworks.
• IT admins buying compact workstations for CAD, visualization or edge AI. Intel says its Arc Pro drivers are certified with ISV apps including AutoCAD, SolidWorks and Revit.
• Hardware enthusiasts who want to see what a liquid-cooled box with two GPUs at up to 290W each looks like.

Big unanswered questions remain: noise, sustained clocks, total power draw, enclosure size, availability outside China and price. Until GUNNIR publishes those, this is a promising concept showing where Intel's partners are headed with Battlemage: compact AI and workstation boxes rather than gaming rigs.
