Intel Xeon Platinum 8276

The Intel Xeon Platinum 8276 is a 28-core, 56-thread processor from Intel, released on 2018-12-10 for the Server/Workstation segment. It is built for Intel Socket 3647 and uses the Cascade Lake architecture, with the codename Cascade Lake-SP. The chip is manufactured on Intel's 14 nm process and integrates 8,000 million transistors. Its base clock is 2.20 GHz, its boost clock is 4.00 GHz, and its TDP is 165. The part number is SRF99CD8069504195501.

Benchmark Performance

The fact pack contains an empty benchmarks array and an avgBenchmarkScore of 0. That means the database has no measured score to analyze for this unit. The only global ranking field is percentileVsAllCpus, which is 50. A 50th percentile placement puts the processor at the median of all CPUs in the database: half of the ranked entries sit above it and half sit below it, though no direct score is present in the record.

Because nearestRivals is empty, there are no rival names, no rival scores, and no deltaPct values to cite. No exact percentage can be computed from this record. The benchmark performance picture is therefore limited to the processor's specification data rather than derived from benchmark results.

On the specification side, the parallel resources are substantial: 28 cores and 56 threads. The base clock of 2.20 GHz and boost clock of 4.00 GHz define the frequency range. The cache hierarchy is documented as 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 38.5 MB of shared L3 cache. These values describe the compute configuration, but without a benchmark score they cannot be converted into a comparative performance figure.

The absence of an avgBenchmarkScore is itself a data point: the value 0 is not a derived performance number, it is the default value stored alongside an empty benchmarks list. One consequence is that the percentileVsAllCpus value of 50 cannot be cross-checked against any listed score. If a user relies on the percentile, they are relying on the database's own ranking system; the fact pack does not expose the underlying score.

Power and Thermals

The only power metric in the fact pack is the TDP of 165. No measured power consumption numbers are included, and no thermal data appear. The 14 nm manufacturing process and the 8,000 million transistor count are the process-level details that accompany this TDP figure. Together, they place the part in a power class that a Socket 3647 server platform must cool. The market segment is Server/Workstation, which is the thermal context implied by the product's intended use.

The integrated graphics field is null, so the processor is not documented with an on-die GPU. That means the thermal load in the record is associated with the CPU proper rather than a graphics block. The fact pack lists no integrated graphics, leaving the CPU cores as the stated compute components.

For cooling tier, the pack does not specify a cooler or heatsink. The available data indicate a 165 TDP part on Intel Socket 3647; the cooling solution is therefore a platform-level decision. In the Server/Workstation segment, the thermal design must accommodate the 165 TDP envelope during boost operation. The 14 nm process is the only process node listed; no other manufacturing detail such as die size is present.

How It Compares

The nearestRivals array is empty. Because of that, this record has no direct comparison to a specific rival processor. There are no names, no scores, no deltaPct values, and therefore no percentage leads or deficits to report. The data instead offers a single broad reference: the 50th percentile versus all CPUs.

No nearest rival is listed, so there is no per-rival paragraph to construct. Against the all-CPU field, the Xeon Platinum 8276 sits exactly at the midpoint. A percentile of 50 is the median placement; it neither flags the processor as a high outlier nor as a low outlier. This comparison is only as strong as the underlying benchmark set, which is empty for this SKU.

If the database had populated benchmark scores, a nearestRivals entry could provide a deltaPct. In this record, that field is an empty list, so any attempt to name a competitor would be unsupported. The empty nearestRivals list distinguishes this record from processors that have nearestRivals entries with deltaPct values. Without such an entry, the data cannot place the Xeon Platinum 8276 ahead of or behind a named competitor.

Platform and Compatibility

The processor uses Intel Socket 3647. Memory support is DDR4, and ECC memory is enabled in the data. The architecture field says Cascade Lake, and the codename field says Cascade Lake-SP. The generation is listed as Xeon Platinum (Cascade Lake-SP). These identifiers define the platform generation.

The part number SRF99CD8069504195501 identifies the exact SKU. The multiplierUnlocked field is false, so the processor is not an unlocked part. The fact pack contains no PCIe information, no memory bus width, and no memory bandwidth, so those compatibility details are absent from this record.

For upgrade path, a system built around this processor must stay on Intel Socket 3647 unless the motherboard is changed. The pack does not list other Socket 3647 processors, so a direct within-socket upgrade cannot be named from the data. The 2018-12-10 release date positions it in the Cascade Lake-SP generation, and any platform compatibility question beyond socket, memory, and ECC would require additional datasheet details.
