Intel Xeon 6553P-B

The Intel Xeon 6553P-B is a 36-core, 72-thread server/workstation processor from Intel, built on the 5 nm Granite Rapids architecture and belonging to the Xeon 6 (Granite Rapids-D) generation. It has a 2.60 GHz base clock, a 4.00 GHz boost clock, a 235 W TDP, 144 MB of shared L3 cache, DDR5 quad-channel memory, and 32 PCIe Gen 5 lanes. The database record for this processor contains no measured benchmark scores and no nearest-rival entries, so the analysis below draws on the full specification block to describe the intended workload profile.

Benchmark Performance

The benchmark fields in the record are effectively empty. The benchmarks array has no entries, the avgBenchmarkScore field is 0, and the nearestRivals array is empty. As a result, there are no exact percentage deltas to quote, no rival scores to compare, and no measured single-thread or multi-thread results. The only ranking field present is percentileVsAllCpus: 50, which places the processor at the median of the database's all-CPU percentile distribution. That 50th percentile cannot be treated as a benchmark score; it is a relative position label, and with avgBenchmarkScore at 0 there is no computed performance value behind it.

From the specification data alone, the intended performance profile is clear. A 36-core, 72-thread processor with a 2.60 GHz base clock and a 4.00 GHz boost clock is built for parallel throughput. The 144 MB shared L3 cache is a large pool for workloads that share data across cores. The memory interface is quad-channel DDR5 at 204.8 GB/s, which gives the cores a wide data path. These are architectural indicators, not measured results; they say what the processor is designed to do, not how it scores in any specific application.

Power and Thermals

The TDP is 235 W. That places the 6553P-B in a high-power class. The process node is 5 nm and the die size is 598 mm², so heat is spread across a large die, but the thermal design still requires a cooling solution capable of handling that power envelope. The record does not specify a cooler, so no cooler size can be cited. What the TDP implies is straightforward: this is not a low-power part, and a system designed for modest cooling loads will not be adequate.

The market segment field is Server/Workstation, which also shapes the thermal expectation. Server cooling is typically designed for sustained all-core operation, and workstation builds usually require robust cooling to manage a 235 W package. Because the socket is Intel BGA 4368, the cooler mounting must match the board layout rather than a generic consumer socket. The processor has no integrated graphics, with integratedGraphics listed as null, so the package does not add graphics-related heat to the thermal budget.

How It Compares

The nearestRivals field in the record is empty. There are no names, no scores, and no deltaPct values to present. Consequently, no comparison can be placed against a specific competing processor. The only comparative anchor is the global percentile field: 50th percentile vs all CPUs. That means the database places this part at the median of every CPU it tracks. It does not identify which CPUs are above or below, and it does not provide the magnitude of any performance gap.

No rival-specific comparison can be made from the data. If a benchmark run and rival list are added later, the deltaPct values would be the relevant numbers; in the current record they do not exist. The empty comparison set is itself a factual statement: at the time of data collection, this processor had not been ranked against other products.

Platform and Compatibility

The socket is Intel BGA 4368. This is a BGA-format socket, so the processor is mounted directly to the board, and the CPU and board should be treated as a combined platform. The architecture is Granite Rapids and the generation is Xeon 6 (Granite Rapids-D). The part is built on a 5 nm process at Intel, with a 598 mm² die. The part number is SRWG5. The production status is Active, and the release date is 2025-02-23.

Memory support is DDR5, with a quad-channel memory bus and 204.8 GB/s of peak bandwidth. ECC memory support is enabled, which is important for servers and workstations that need error checking in RAM. The PCIe field is Gen 5, with 32 lanes (CPU only). The "CPU only" qualifier means those lanes are native to the processor package; the record does not list additional chipset lanes. There is no integrated graphics, so a separate graphics adapter is required if display output is needed.

The multiplier is locked, with multiplierUnlocked set to false, so the processor is not designed for unlocked overclocking. The launch MSRP is $2402. The upgrade path is dictated by the BGA socket and the server/workstation platform: a CPU upgrade means working with the motherboard's supported processor compatibility, and the active production status suggests continued availability.

Who Should Consider It

Because the benchmark score is absent, this recommendation is based entirely on the specification data. The 6553P-B is a candidate for multi-threaded server workloads: 36 cores and 72 threads provide a large parallel execution resource, and the 144 MB shared L3 cache can hold substantial working sets for many cores. The 2.60 GHz base clock is moderate, which is consistent with sustained all-core operation in a server environment. The 4.00 GHz boost clock gives headroom for short bursts.

It is also a candidate for memory-integrity-sensitive applications. Quad-channel DDR5 with ECC support and 204.8 GB/s bandwidth makes it suited to workloads where memory reliability matters and bandwidth is a limiting factor. These workload classes are inferred from the ECC plus quad-channel DDR5 combination; the record does not include application-specific benchmarks.

For I/O-centered workstation builds, the 32 PCIe Gen 5 lanes (CPU only) support a number of high-speed devices. The record does not specify lane splitting, but the lane count and generation are enough to signal a platform designed for expansion rather than a compact client PC. The absence of integrated graphics pushes the system toward discrete compute or display cards.

The 235 W TDP means anyone considering this processor should plan for a cooling system that can handle a high-power CPU in continuous use. It is not a fit for fanless builds or low-power appliances. In short, the target use cases are parallel CPU work, ECC-protected memory workloads, and PCIe Gen 5 expansion, all within a server or workstation chassis.

Single-Thread vs Multi-Thread Behavior

The record does not include separate single-thread and multi-thread benchmark scores. There is no way to state a single-thread score or a multi-thread score from the data. What can be described is the architectural split. The processor has 36 cores and 72 threads, so the multi-thread side has a large execution footprint. The base clock of 2.60 GHz is a moderate frequency for all-core operation; the boost clock of 4.00 GHz is the upper boundary for lightly threaded bursts.

The cache hierarchy reinforces a multi-thread-oriented design: 112 KB of L1 and 2 MB of L2 per core, plus a shared 144 MB L3. The per-core L2 gives each core a private working area, while the large shared L3 allows data to be exchanged across cores without going back to memory. The 204.8 GB/s DDR5 bandwidth complements that cache arrangement for multi-threaded data streaming.

Single-thread behavior, by contrast, depends mostly on the 4.00 GHz boost clock and the per-core L1/L2 caches, but without benchmark numbers, no relative strength can be claimed. The 50th percentile vs all CPUs does not break down by thread count; it treats the processor as a single unit. The safest statement from the data is that the hardware is built around multi-threaded throughput, with a boost clock that can lift lightly threaded work when needed, but measured proof is not present.
