About Intel Xeon 6546P-B
The Intel Xeon 6546P-B is a 32-core, 64-thread server processor built on Intel's 5 nm Granite Rapids architecture. It operates at a 2.30 GHz base clock and a 3.50 GHz boost clock, with a 195 W TDP. This is a soldered BGA part, meaning it is permanently attached to the motherboard and not a drop-in upgrade for existing systems. The data shows it sits at the 50th percentile of all CPUs tracked in the database, with an average benchmark score of 0, indicating no recorded performance results yet. Its positioning is therefore derived from its specification sheet rather than measured performance.
Who Should Consider It
The 32 cores and 64 threads make this processor a strong candidate for heavily threaded server and workstation workloads. Virtualization, database hosting, and large-scale data processing all benefit from the high core count and the 128 MB shared L3 cache, which reduces memory latency for frequently accessed data. The quad-channel DDR5 memory bus with 204.8 GB/s of bandwidth ensures that the cores are fed with data quickly, which is essential for memory-bound tasks like in-memory analytics or high-frequency trading. The 32 Gen 5 PCIe lanes allow for multiple high-speed NVMe drives or GPU accelerators, making it suitable for storage-heavy servers or compute nodes for machine learning inference.
The 50th percentile ranking among all CPUs in the database suggests it is not a top-tier part when compared to the entire range of consumer and server processors. However, that database includes many lower-core-count consumer chips, so the Xeon’s strength lies in its multi-threaded throughput and memory capacity, not in raw single-thread speed. It has no integrated graphics, so a discrete GPU is mandatory for any display output or compute task. This processor is best suited for a pre-built server or workstation where the soldered BGA socket is acceptable, and where the system is expected to run 24/7 under sustained load.
Power and Thermals
The 195 W TDP places this processor in the high-power class. This is not a chip for a small form factor desktop; it requires a robust cooling solution. Because it is a BGA package, the cooling is typically integrated into the system by the manufacturer, so the end user does not select a cooler. A capable air cooler or a substantial liquid cooling solution is necessary to handle the sustained heat output. The 5 nm process node helps with efficiency, but 195 W is still a significant thermal load. The die size of 598 mm² indicates a large physical chip, which spreads heat across a wide area, but also requires a large cold plate or heat sink to effectively dissipate it. The 195 W TDP also implies a power delivery system capable of sustained current draw, so the motherboard must have a robust VRM design.
Single-Thread vs Multi-Thread Behavior
The base clock of 2.30 GHz and boost clock of 3.50 GHz show a moderate uplift of 1.20 GHz for single-threaded workloads. This means that tasks which rely on a single core, such as legacy software or lightly threaded applications, will see a reasonable performance level, but not the highest available. The 3.50 GHz boost is not extreme, but it is sufficient for administrative tasks or light scripting. The real strength is in multi-threaded performance. With 32 cores and 64 threads, the processor can execute a massive number of parallel tasks simultaneously. The 128 MB shared L3 cache is a key asset here, as it allows all cores to access a large pool of data without hitting the memory bus. The 2 MB L2 cache per core and 112 KB L1 cache per core provide fast local storage for each core. The quad-channel memory bandwidth of 204.8 GB/s ensures that the cores are not starved for data. The split is clear: this is a multi-threaded workhorse, not a single-thread speed demon.
Platform and Compatibility
The socket is Intel BGA 4368, which is a soldered, non-upgradeable interface. This means the processor is permanently attached to the motherboard, so there is no upgrade path for the CPU itself. The system must be purchased as a complete unit. It supports DDR5 memory in a quad-channel configuration, with ECC support, which is critical for server reliability and data integrity. The memory bandwidth is 204.8 GB/s, which is a high figure for a quad-channel setup. The processor provides 32 Gen 5 PCIe lanes from the CPU, which can be used for high-speed storage devices, network adapters, or GPU accelerators. It has no integrated graphics, so a discrete GPU is required for any video output. The part is in active production, and it was released on February 23, 2025. The multiplier is locked, so overclocking is not an option. The part number is SRWFZ.
How It Compares
The FACT PACK lists no nearest rivals for this processor. Therefore, a direct delta comparison against specific competing models is not available from the data. The processor’s percentile rank is the 50th percentile among all CPUs in the database. This is a notable position for a 32-core server chip, because the database includes a wide range of consumer and server parts. The average benchmark score is 0, indicating that no benchmark results have been recorded for this part yet, so the percentile is derived from its specification rather than measured performance. In the absence of rival data, the 50th percentile is the only positional reference point. It suggests that, based on its core count, memory bandwidth, and cache, it sits in the middle of the entire tracked CPU population. This is an unusual position for a high-core-count server part, but it reflects the database’s mix of consumer and enterprise processors.
