In brief
- BlueField-4 STX appeared at multiple partner booths at OCP 2026.
- The card has a single Vera CPU package and SOCAMM memory.
- The design includes high-density PCIe and system-connectivity connectors, as well as an M.2 slot.
- No ConnectX-9 SuperNIC was seen on the card; pricing and release information were not announced.
NVIDIA’s BlueField-4 STX server card was shown at OCP 2026 for Context Memory (CMX) systems. According to ServeTheHome’s coverage from several partner booths at the event, the design stands out as a smaller, lower-cost option compared with the previously seen dual-Vera CPU configuration. The card’s price, release schedule and final product specifications have not been shared.
What does the BlueField-4 STX design include?
This solution in the BlueField-4 family is built more like a high-performance, single-socket server platform than a traditional DPU. ServeTheHome reports that the card contains a single Vera CPU package. This is the main difference from the previously shown BlueField-4 configuration, which used two Vera CPUs and SOCAMM memory.
The card’s processor and memory are soldered in place. The source says it uses LPDDR5X memory instead of conventional DDR5 DIMM slots. Despite its small size, the card should not be thought of as a simple peripheral, given the processor and memory it contains. According to the comparison in the report, its motherboard is on a similar scale to server platforms with a 16-channel CPU socket.
Memory and onboard connectivity
The examples shown at OCP 2026 use SOCAMM memory. ServeTheHome suggests that this memory layout could make it easier to fit a heatsink or liquid-cooling block. However, the source does not provide a definitive technical list of the product’s final cooling requirements or supported cooling solutions.
The card also has an M.2 slot and high-density PCIe and system-connectivity connectors. Its intended use for the M.2 slot has not been explained; according to the source, such slots are generally used for operating system drives. The suggestion that the card could be better suited to automated assembly is also an assessment based on its design, not a stated product feature.
Another point highlighted by ServeTheHome is that no ConnectX-9 SuperNIC was seen on the cards on display. The publication says it had expected to see one, but did not spot it in photos or at the booths. More product information is therefore needed before drawing firm conclusions about the card’s networking hardware and final connectivity options.
What it could mean for architecture and visualization workflows
BlueField-4 STX is not design software or a workstation graphics card; it is a server platform for CMX systems. So it cannot be said to directly change modeling, rendering or scene-setup workflows in architecture firms. Potentially relevant applications could include enterprise systems where many users and tools rely on memory or server infrastructure; the source does not describe any specific use case for architecture workloads.
Technical teams considering this card should review compatibility, connectivity, cooling and licensing once the final technical documentation is published. The source provides no information about operating system support, software compatibility or licensing. The absence of ConnectX-9 from the examples on display also leaves questions about the final network configuration.
Pricing and product timeline remain uncertain
ServeTheHome believes that the single-Vera CPU design could help bring CMX systems to market by costing less than the dual-Vera option. This is neither an announced price nor a release commitment from NVIDIA. The report contains no pricing, sales-date or availability information.
For now, BlueField-4 STX should be viewed as a platform shown at OCP 2026 for teams interested in server and memory infrastructure. It is too early for architecture and visualization firms to make a direct purchasing decision; they should wait for details on the final configuration, connectivity options and supported software.

It is too soon to say that BlueField-4 STX is a direct rendering or modeling upgrade for architecture firms. The news points instead to a new form of server infrastructure focused on CMX. The single-Vera CPU design is reported to potentially cost less, but no pricing, product timeline or licensing information is available.
For firms in Turkey, the most sensible approach is to keep an eye on this card only if their existing server plans call for CMX. Cooling, connectivity and software support should be clarified before investing in the hardware. The absence of ConnectX-9 from the examples on display is another uncertainty to bear in mind until the final configuration is announced.
