Intel Xeon MP 3.0

The Intel Xeon MP 3.0 is a single-core server processor from Intel's Gallatin line, released in March 2004. It operates at a fixed 3.00 GHz base clock, supports two threads via Hyper-Threading, and carries a 4 MB L3 cache. With a 50th percentile ranking in the database, it sits exactly at the median of all CPUs tracked, making it a representative midpoint in overall performance. This analysis examines its behavior, target workloads, platform fit, and competitive standing based on the available data.

Single-Thread vs Multi-Thread Behavior

The Xeon MP 3.0 is built on the NetBurst architecture, a design that prioritized high clock speeds through deep pipelines. Its single physical core runs at 3.00 GHz with no boost capability, meaning the clock is constant under all loads. For single-threaded tasks, this is the primary driver of performance. The cache hierarchy — 8 KB of L1, 512 KB of L2, and a substantial 4 MB L3 — helps mitigate memory latency, especially for workloads with large working sets that fit within the L3. In real-world terms, legacy server applications that are not threaded, such as certain database queries or single-process financial calculations, would see the full benefit of the 3.00 GHz clock and the large cache.

Multi-threaded behavior is limited by the single core and two logical threads. Hyper-Threading allows the operating system to schedule two threads on the same core, but they share execution resources, so gains are modest compared to true dual-core designs. The 50th percentile ranking suggests that, on average, the processor delivers median performance across the entire database, which includes both older and much newer CPUs. For multi-threaded workloads that scale beyond two threads, this chip will quickly become a bottleneck. The lack of a boost clock also means no transient performance headroom. The 4 MB L3 is a notable asset, as it was large for its era and can improve hit rates for data-intensive server tasks, but it does not compensate for the absence of additional cores.

Who Should Consider It

Given its market segment of Server/Workstation and its end-of-life production status, the Xeon MP 3.0 is not a candidate for new systems. It is relevant only for legacy environments that already use Socket 604 motherboards and require a drop-in replacement or an upgrade from lower-clocked parts. Workloads that could still benefit include single-threaded transaction processing, legacy database servers, or applications that depend on ECC memory for data integrity — the processor supports ECC DDR1, which is essential for error-free operation in mission-critical servers. The 85 W TDP is modest, but the platform's memory and bus interfaces are obsolete, so the chip is unsuitable for modern high-throughput workloads such as virtualization, big-data analytics, or contemporary web serving.

The multiplier is locked, so overclocking is not possible, which further restricts its appeal to fixed-clock server environments. The processor's 50th percentile rank means it is neither a standout nor a laggard in the database, but that ranking is heavily influenced by the mix of CPUs in the database. For anyone maintaining a legacy Socket 604 system, the Xeon MP 3.0 offers a reliable, if unremarkable, single-thread performance level, especially with its 4 MB L3 cache and ECC support. For all other users, modern multi-core processors provide far better scalability and efficiency.

Platform and Compatibility

The Xeon MP 3.0 uses Intel Socket 604, a socket designed for multi-processor servers. The platform supports DDR1 memory with ECC, which is a requirement for high-reliability computing. The fact pack does not list PCIe support, indicating that the chip relies on older bus architectures such as AGP or PCI-X, which were common in 2004-era servers. There is no integrated graphics, so a discrete GPU or a server BMC is necessary for display output. The processor is manufactured on a 130 nm process, with a die size of 269 mm², reflecting the large L3 cache. The part number is SL79V.

The upgrade path is effectively nonexistent because the processor is end-of-life and no newer CPUs are compatible with Socket 604. The memory type, DDR1, is long obsolete, and the lack of PCIe means modern expansion cards cannot be used. The release date of March 2004 places it in the early NetBurst era, and its architecture, codenamed Gallatin, was the top-tier Xeon MP variant. The platform's limitations — no boost clock, locked multiplier, and single-core design — make it a fixed-performance solution for legacy applications. The 85 W TDP is modest, but the platform's power delivery and cooling requirements are tied to the server chassis, not the CPU alone.

How It Compares

The fact pack provides no nearest rival data, so direct comparisons to specific competing processors are not possible. The only comparative metric available is the 50th percentile ranking, which indicates that the Xeon MP 3.0 sits exactly at the median of all CPUs in the database. This means that half of all tracked processors are faster and half are slower, but without individual scores, the exact deltas cannot be quantified. Given its single-core, two-thread design, it is reasonable to infer that any modern multi-core processor would outperform it in multi-threaded workloads by a wide margin, though no numbers are available to support that claim.

In single-threaded tasks, the 3.00 GHz clock and 4 MB L3 cache could still hold its own against many mid-range CPUs of its generation, but again, the absence of rival scores precludes a precise comparison. The processor's position in the database is defined more by its architectural characteristics than by measured performance, as the benchmark array is empty. The 50th percentile is a relative rank, not an absolute score, and it should be interpreted cautiously given the heterogeneous mix of CPUs in the database. Without benchmark data, any competitive analysis must rely on the raw specifications: one core, two threads, a 3.00 GHz base clock, and a large L3 cache.

Benchmark Performance

The benchmark array for the Xeon MP 3.0 is empty, and the average benchmark score is recorded as 0. This indicates that no performance tests have been run or recorded for this processor in the database. Consequently, the only performance indicator is the 50th percentile rank, which is a composite measure of all CPUs in the database. This rank suggests that, on average, the processor delivers median performance, but the lack of specific scores means that exact deltas versus rivals cannot be computed. The 0 average score is not a real measurement but rather a placeholder reflecting the absence of data.

The processor's performance must therefore be inferred from its specifications. The 3.00 GHz base clock, combined with a single core and two threads, defines its ceiling for single-threaded and multi-threaded throughput. The 4 MB L3 cache is a significant asset for workloads with large working sets, as it reduces the need to access slower DDR1 memory. The 85 W TDP indicates a moderate power draw, but efficiency is not a strong point of the NetBurst architecture. In the context of the database, the 50th percentile means that if all CPUs were ranked by performance, this chip would be exactly in the middle. That is a meaningful statement, but it does not reveal how it performs against specific rivals, because those rivals are not listed.

In summary, the Intel Xeon MP 3.0 is a single-core server processor from 2004, characterized by a high clock speed, a large L3 cache, and ECC memory support. Its single-thread performance is its primary strength, while its multi-threaded capability is limited to two logical threads. The platform is obsolete, and the lack of benchmark data and rival comparisons restricts the analysis to architectural inference. The 50th percentile rank places it at the median of all CPUs in the database, but without further data, that is the extent of the quantitative assessment.
