Intel Xeon 5150

The Intel Xeon 5150 is a two-core, two-thread processor from Intel, built on the Core 2 architecture and codenamed Woodcrest. Its base clock is 2.67 GHz, with no boost clock listed. The processor targets the server/workstation market segment, uses Intel Socket 771, supports DDR2 memory with ECC, and carries a TDP of 65 W. It was manufactured on a 65 nm process, released on 2006-06-25, and is now marked end-of-life. In the database, the Xeon 5150 sits at the 50th percentile of the all-CPU distribution, while its average benchmark score is listed as 0 because the benchmark record set is empty.

Who Should Consider It

The data for this processor contains no scored benchmark entries, so workload recommendations have to be built from the structural fields rather than from measured performance. The two cores and two threads establish a hard execution ceiling: at most two concurrent threads can be processed. That makes the Xeon 5150 a candidate for workloads that are single-threaded or only lightly threaded, where two physical cores are enough and no more are required. It is not a candidate for heavily parallel workloads that expect to spread across many threads, because the processor simply does not expose additional logical resources beyond its two threads.

The 50th percentile position is the only ranking signal in the record. It places the processor in the middle of the database's all-CPU distribution, not at the top and not at the bottom. The average benchmark score is 0, but because the benchmark records are empty, that value should be read as a missing-data placeholder rather than as a measured performance result. In other words, the database cannot substantiate a claim that this part is faster than another part. It can only say that, in the overall ranking, this processor is positioned at the median.

The ECC memory support and the server/workstation segment marker are relevant for anyone choosing this chip. ECC support implies a reliability-oriented memory path, which is a typical requirement for legacy server or workstation boards. The release date of 2006 and the end-of-life status suggest this is a part for maintaining existing systems or for use in a platform that is already qualified, not for a new high-performance build. Office-style productivity and basic server tasks that can stay within a two-thread envelope are the most plausible workload profiles. Anything requiring more than two concurrent threads will hit the structural limit of this processor before any performance or benchmark question is reached.

No gaming or content-creation scores are present in the record. Therefore, the database provides no basis for recommending the Xeon 5150 for those workloads based on measured capability. What the data does show is a median-ranked, two-thread processor from the 2006 era. A user should consider this part only if the workload fits within that envelope and if the Socket 771, DDR2, ECC platform is already part of the plan.

Power and Thermals

The thermal design power is 65 W. That places the Xeon 5150 in a modest power class for a server/workstation processor. The 65 nm manufacturing process is the only process-node figure in the data, and it combines with the 65 W TDP to define the thermal envelope that a cooling solution must address. The record does not include measured temperatures, cooler size, or thermal headroom, so the cooling tier can only be inferred from the TDP class.

Because no boost clock is listed, there is no higher-frequency transient state in the data. The processor operates with a 2.67 GHz base clock as its only listed frequency. This makes the thermal behavior more predictable than a processor with an explicit boost state, since the sustained frequency is the same as the base frequency in the record. Still, the absence of a boost clock does not mean the processor cannot generate heat at the base clock; it simply means the dataset provides no additional frequency state to model.

For cooling purposes, the 65 W TDP is the key number. A solution designed for the 65 W class should be sufficient, but the exact cooler type is not specified in the database. Socket 771 mechanical mounting is the only physical attachment detail given. Since the production status is end-of-life, practical cooling experience will likely come from existing Socket 771 server or workstation chassis rather than from current cooler listings. The data does not support any claim about liquid cooling, larger air coolers, or custom thermal solutions; it supports only the 65 W TDP and the 65 nm process as thermal inputs.

Platform and Compatibility

The platform anchor for the Xeon 5150 is Intel Socket 771. The memory support field lists DDR2, and the ECC flag is true. That combination points toward a server/workstation board designed for DDR2 ECC memory. No PCIe information is included in the record, so expansion and bandwidth compatibility must be checked against the motherboard rather than assumed from this processor entry.

The processor is based on the Core 2 architecture with the Woodcrest codename. The generation field identifies it as a Xeon (Woodcrest) part. The process node is 65 nm. The release date is 2006-06-25, and the production status is end-of-life. These facts frame the platform as a legacy server/workstation environment rather than a current or forward-looking one.

The multiplier is not unlocked. That means the processor does not offer an unlocked multiplier for frequency adjustment. Whether the platform allows any frequency manipulation is outside the data, but the processor field itself indicates a locked multiplier. This matters for upgrade and configuration planning: the Xeon 5150 is not presented as an enthusiast overclocking part.

Upgrade path considerations are limited by the data. The record lists no other processors in a nearestRivals relationship to the Xeon 5150, and there are no benchmark records to indicate how it would perform against a potential replacement. The only confirmed upgrade-relevant facts are Socket 771, DDR2 memory, and ECC support. A user who wants to move to a different processor on the same platform would need to consult motherboard documentation, because the database entry does not provide alternative-processor compatibility. The end-of-life status further suggests that new production units are not expected, so platform availability is tied to existing Socket 771 boards and DDR2 memory supplies.

How It Compares

The nearestRivals data is empty in this record. There are no rival names, no rival scores, and no deltaPct values to report. Consequently, this section cannot provide the usual one-paragraph-per-rival comparison against named competitors. Any such comparison would require data that is not present.

The only comparative signal in the database is the percentileVsAllCpus value of 50. This indicates a median placement in the all-CPU distribution. One way to read this is that, in the database's ranking, half of the CPU population falls below this processor and half falls above it. That is a positional statement, not a measured performance statement. The average benchmark score is listed as 0, and the benchmark records are empty, so the median percentile cannot be tied to a specific benchmark mean.

Without nearestRivals, no statement such as "the Xeon 5150 is ahead of processor X" or "it trails processor Y by Z percent" can be made from this dataset. The record simply does not include the necessary comparison metrics. The 50th percentile is the only ranking anchor, and it should be treated as a coarse placement rather than a precise performance relationship to any other processor. For users who want to see where this chip stands against a specific rival, the answer from the available data is that the comparison cannot be constructed.

Single-Thread vs Multi-Thread Behavior

The core count and thread count are both 2. This one-to-one ratio means the Xeon 5150 provides two physical execution threads and no additional logical threads beyond that. In single-threaded workloads, one core can execute at the listed 2.67 GHz base clock. There is no boost clock entry to raise the frequency for one core or for any other scenario. Therefore, single-thread behavior is defined entirely by the 2.67 GHz base clock and the 4 MB L2 cache.

Multi-threaded workloads can use both cores, giving exactly two concurrent threads. Because the thread count equals the core count, the data shows no simultaneous multithreading effect. A workload that needs three or more threads will have to share the two available threads through operating-system scheduling, but the processor itself cannot execute more than two threads at the same time. This is a hard structural limit in the data.

The cache information includes only a 4 MB L2 cache. No L1 size, no L3 size, and no total L3 value are present in the record. The data also does not specify whether the 4 MB L2 is shared between the two cores or partitioned per core. For real workloads, the 4 MB L2 is a useful detail, but without memory bandwidth or latency figures, its effect on single-thread versus multi-thread performance cannot be quantified from this entry alone.

The important split for this part is not between a high single-core boost state and a lower all-core state, because no boost clock is listed. The split is between one thread and two threads. A single-thread workload uses one core and leaves the other idle. A two-thread workload engages the full processor. The 50th percentile ranking and the 0 average benchmark score mean the database cannot translate these architectural characteristics into specific performance numbers. The Xeon 5150 remains, in the available data, a two-thread Woodcrest processor on a 65 nm process, with a 2.67 GHz base clock, a 65 W TDP, and a 4 MB L2 cache.
