The Intel Xeon 6553P-B is a 36-core, 72-thread system-on-chip based on the Granite Rapids-D architecture, designed for networking and edge workloads such as vRAN, media transcoding, and Edge AI inference, with integrated 100GbE, QuickAssist, and Media Transcode Accelerator.
Intel’s Xeon 6553P-B is a 36-core/72-thread Granite Rapids-D SoC built for networking and edge servers. It runs at 2.6 GHz base and up to 4 GHz turbo, with 144MB of L3 cache, four DDR5-6400 channels, up to 32 PCIe 5.
0 lanes plus additional PCIe 4.0 lanes, and integrated dual 100GbE alongside Intel QuickAssist and Media Transcode Accelerator. This makes it a strong fit for 5G vRAN, edge AI, media gateways, and NFV, though its BGA4368 soldered packaging and high TDP limit it to purpose-built platforms.
Specifications
Performance
Excellent multi-threaded throughput for edge and server productivity workloads; best-in-class when paired with its integrated accelerators.
Very strong for consolidated virtualized workloads at the edge, with VT-x, VT-d, and large memory support.
Capable but not targeted at gaming; single-thread performance is good, but high core counts and server-optimized power profiles don’t translate into gaming advantages over mainstream desktop CPUs.
Good performance per watt for its segment, but 235W TDP and BGA packaging mean it is best used in systems designed specifically for this SoC.
- •High single-core boost up to 4 GHz helps frame rates in CPU-limited titles
- •Lack of integrated graphics requires a discrete GPU
- •Not tuned for gaming workloads; mainstream desktop CPUs often equal or beat it at lower power
- •AMX and DL Boost accelerate CPU-based inference workloads
- •Integrated Media Transcode Accelerator helps video analytics pipelines
- •For large-scale training, GPUs or dedicated accelerators are still preferred

History
The Xeon 6553P-B emerged as part of Intel’s Granite Rapids-D Xeon 6 SoC family, which succeeded the Ice Lake-D Xeon D line for networking and edge. Announced as Intel shifted its Xeon lineup toward domain-specific accelerators and integrated I/O, Granite Rapids-D focused on 5G vRAN, media transcode, and edge AI by consolidating P-cores, 100GbE, QuickAssist, and a Media Transcode Accelerator onto a single BGA4368 die.</br>System vendors like Supermicro quickly adopted the 6553P-B in compact edge servers such as the SYS-112D-36C-FN3P, pairing 36 P-cores with dual 100GbE and a PCIe 5.
0 x16 slot for GPUs or accelerators. These platforms targeted telcos and cloud providers deploying vRAN and Open RAN, where higher core density, integrated accelerators, and improved performance per watt compared to older Xeon D systems became key selling points.</br>Over time, the Granite Rapids-D lineup expanded to include 8-channel memory variants and higher core counts, but the 6553P-B remained a key 36-core option balancing compute, I/O, and power for space-constrained edge and networking appliances.
