ASRock DeskMini B860 + Core Ultra 7 265 vs GEEKOM IT13 2026 Edition

Sycom and DunamisTek both offered complete DeskMini B860 systems with the 20-core Core Ultra 7 265, confirming a real build path. Their memory, storage, cooling, and software choices do not define this barebone record.

The Core Ultra 7 356H has four performance cores, eight efficiency cores, and four low-power efficiency cores for 16 total cores and threads, with a maximum turbo frequency of 4.7 GHz. This is a processor specification, not measured IT13 performance.

Manufacturer processor specification · Intel Core Ultra 7 356H

Intel rates the Core Ultra 7 265 for 65W base power and up to 182W turbo power, while ASRock limits the DeskMini B860 to 65W processors and supplies a 120W adapter. Sustained 265 performance therefore depends on the chassis BIOS limits and cooler rather than the processor's unrestricted desktop maximum.

GEEKOM identifies the cooling system as IceBlast 2.0 and describes it as efficient and quiet. No exact-chassis sustained benchmark was available to quantify that claim.

The Mini-STX chassis has no PCIe graphics-card position. Gaming and GPU-compute capability is limited to the four-Xe-core Intel Graphics engine integrated into the selected Core Ultra 7 265.

Intel specifies four Xe cores, a 2.45 GHz maximum graphics frequency, and hardware ray tracing for the Core Ultra 7 356H's Intel Graphics. No exact IT13 2026 gaming result was found.

ASRock permits CPU coolers up to 47mm tall. CT.nl recommended a larger-fan low-profile cooler such as the Noctua NH-L9i-17xx or Alpenfohn Silvretta to reduce the boxed cooler's load noise.

The manufacturer calls the IceBlast 2.0 system quiet but does not publish a sound-pressure level or exact-chassis thermal result for the Ultra 7 configuration. Older 13th-generation IT13 and IT13 Max results are not substituted.

GEEKOM specifies a 19 V, 6.32 A external adapter, equivalent to approximately 120 W of rated capacity. This is not measured wall-power consumption.

The board provides one PCIe 5.0 x4 M.2 2280 slot, one PCIe 4.0 x4 M.2 2280 slot, and two SATA 6Gbps connectors for 2.5-inch drives up to 9.5mm thick. ASRock includes the proprietary SATA power/data cables.

CT.nl measured up to 3.8GB/s through rear Thunderbolt 4, about 2.03GB/s through the front 20Gbps USB-C port, and roughly 300MB/s over 2.5GbE on its DeskMini B860 test build.

Unlike most mini PCs, the LGA1851 processor can be replaced independently. ASRock officially limits the system to supported Core Ultra Series 2 processors at 65W or below and requires integrated graphics because the chassis has no GPU slot.

The Ultra 7 configuration supports dual-channel DDR5 memory up to 64GB and provides two M.2 storage paths. GEEKOM identifies the primary and secondary paths as PCIe, but conflicting generation labels on the shared product page are omitted here.

A US eBay importer listed exact global part 90BXG5501-A10GA0W for $295 when checked. ASRock did not publish a global USD MSRP, and the listing does not include the Core Ultra 7 265, memory, storage, wireless, or Windows.

Intel publishes a recommended customer price range of $384 to $394 for the boxed Core Ultra 7 265. The total working-system cost must also include memory, storage, wireless if wanted, and an operating system.

The socketed CPU, two SO-DIMMs, two M.2 drives, two SATA drives, and optional wireless module are independently replaceable. This avoids the motherboard-level memory and storage repair limits common to soldered mini PCs.

Because this is a parts build, the barebone, processor, memory, storage, and optional wireless card may each have separate warranty providers and terms. ASRock's global product page does not publish one universal coverage period for part 90BXG5501-A10GA0W.

ASRock continued publishing B860M-STX firmware updates in August 2026, including CPU microcode, Intel Management Engine, and compatibility changes. Builders should verify CPU support and update procedure before changing processors.
