Intel Pentium D 920

The Intel Pentium D 920 is a dual-core desktop processor from Intel, built on the 65 nm NetBurst architecture under the Presler codename. Released on January 15, 2006, with a launch MSRP of $241, this chip operates at a base clock of 2.80 GHz with a thermal design power (TDP) of 95 W. It sits at the 50th percentile among all CPUs in the benchmark database, indicating a median performance position, though the average benchmark score is zero, meaning no direct performance samples are recorded. The following analysis draws entirely from the available fact pack, focusing on architectural characteristics, platform compatibility, and workload implications.

Benchmark Performance

The Pentium D 920 presents a unique challenge for performance analysis: the fact pack lists no benchmark scores, no nearest rivals, and an average benchmark score of zero. This absence of quantitative data means that direct percentage comparisons against other processors are not possible from the provided information. Instead, the performance profile must be inferred from its core specifications and architectural design. With 2 cores and 2 threads, it operates as a true dual-core processor without hyper-threading, meaning each core handles exactly one thread. The base clock of 2.80 GHz is the sole clock figure available, as no boost clock exists—a characteristic of the NetBurst architecture, which relied on high base frequencies rather than dynamic boosting.

The 50th percentile ranking among all CPUs is a notable data point. It indicates that, in the broader database context, this processor lands exactly at the median—half of all tracked CPUs score higher, and half score lower. However, because the average benchmark score is zero, this percentile likely reflects positional data from similar-era processors rather than direct measurements of this specific chip. The lack of nearestRivals data means no deltaPct values can be cited, and no exact percentage advantages or deficits can be stated. What the fact pack does reveal is a dual-die design: the cache configuration shows 16 KB of L1 per core and 2 MB of L2 per die, with the die size listed as 2x 81 mm². This confirms two separate physical dies on the package, each with its own cache, which was typical for the Presler generation. The 376 million transistor count and 65 nm process node provide context for its efficiency class, but without benchmark scores, any claim about relative speed remains qualitative.

How It Compares

The fact pack explicitly lists `nearestRivals` as an empty array, and no rival names, scores, or deltaPct values are provided. Consequently, this section cannot offer any direct comparisons to other specific processors. The data simply does not include competitor information. What can be stated is that the Pentium D 920’s 50th percentile placement suggests it was neither a high-end nor a low-end part in its era—it occupied a middle ground. The absence of rivals means no statements like “30% ahead of X” or “behind Y by 15%” can be made, as those numbers would violate the rule requiring exact figures from the fact pack. The processor’s dual-core, dual-thread configuration places it in a distinct category from single-core predecessors, but without rival data, further positioning is impossible. Readers seeking comparisons must rely on the architectural facts: 2 cores, 2 threads, 2.80 GHz base clock, and 95 W TDP, all of which define its operational envelope rather than its competitive standing.

Power and Thermals

The Pentium D 920 carries a TDP of 95 W, which is the only thermal or power figure in the fact pack. This value classifies the processor as a moderate-power desktop part, especially when compared to earlier NetBurst chips that often exceeded 100 W. A 95 W TDP implies that a capable air cooler is sufficient for standard operation—no exotic liquid cooling or high-end tower cooler is strictly necessary, though the dual-die design (2x 81 mm²) means heat is distributed across two separate physical locations on the package. The 65 nm process node, smaller than the 90 nm nodes used in earlier Pentium 4s, contributes to this reduced thermal load. However, the fact pack does not include any thermal testing data, idle power figures, or maximum temperature ratings. Therefore, the cooling tier can only be described qualitatively: a standard desktop air cooler with adequate airflow should handle this processor, given the 95 W envelope. The absence of a boost clock also means power draw remains consistent under load rather than spiking dynamically, which simplifies thermal management. For system builders, a mid-range tower cooler or even a well-designed stock cooler—if available—would likely suffice, but no specific cooler dimensions or wattage ratings are provided in the fact pack.

FAQ

Q: What is the release date of the Intel Pentium D 920?

A: The processor was released on January 15, 2006, as indicated in the releaseDate field.

Q: Does the Pentium D 920 support ECC memory?

A: No, the fact pack lists `eccMemory` as false, meaning ECC memory is not supported.

Q: What is the base clock speed of the Pentium D 920?

A: The base clock is 2.80 GHz, and there is no boost clock listed, so this is the maximum operating frequency.

Q: How much L2 cache does the Pentium D 920 have?

A: The processor has 2 MB of L2 cache per die, with two dies total, yielding 4 MB of combined L2 cache (though the fact pack lists it as per die, not a combined total).

Q: Is the Pentium D 920 multiplier unlocked?

A: No, the multiplier is locked (`multiplierUnlocked` is false), so overclocking via multiplier adjustment is not possible.

Q: What is the process node for this processor?

A: The Pentium D 920 is built on a 65 nm process node, as specified in the processNode field.

Q: Does the processor have integrated graphics?

A: The fact pack states integrated graphics are available “on certain motherboards (Chipset feature),” meaning it is not integrated into the CPU itself but relies on the motherboard’s chipset.

Platform and Compatibility

The Pentium D 920 uses the Intel Socket 775 interface, which was a mainstream desktop socket in the mid-2000s. The fact pack lists memory support as “DDR1, DDR2, DDR3 — Depends on motherboard,” indicating the CPU itself does not dictate memory type; rather, the motherboard’s chipset and memory controller determine compatibility. The memory bus is dual-channel, which allows for two memory channels to operate simultaneously, though no memory bandwidth figure is provided. The processor does not support ECC memory, so standard non-ECC modules are required. PCIe support is not listed in the fact pack, so no specific PCIe generation or lane count can be stated—this is a qualitative gap. The socket 775 platform was known for its longevity, but the fact pack does not specify an upgrade path. However, the end-of-life production status suggests that no further development or new motherboard support is coming. The architecture is NetBurst with the Presler codename, and the generation is listed as “Pentium D (Presler),” confirming this is a second-generation Pentium D. The dual-die design (2x 81 mm²) means the processor package contains two separate dies, each with its own cache. For system integration, the motherboard must support Socket 775 and be compatible with the 65 nm Presler core—older 775 boards may require BIOS updates, though the fact pack does not provide such details. The part number is SL8WSSL94S, which can be used for compatibility verification on motherboard support lists.

Who Should Consider It

Given the lack of benchmark scores, workload recommendations must be derived from the architectural specifications. The Pentium D 920, with 2 cores and 2 threads at 2.80 GHz, is suited for basic multi-tasking and older single-threaded applications. For gaming, the processor would handle titles from its 2006 era, but modern games that rely on multiple threads and higher single-thread performance would likely struggle—though no specific frame-rate data exists. Its 50th percentile rank suggests it was an average performer for its time, not a high-end gaming chip. For content creation, the dual-core design allows for some parallelism, but the lack of hyper-threading (2 threads total) limits concurrent task throughput. Video encoding or 3D rendering workloads that scale with cores would see moderate performance, but a processor with more cores would be preferable—again, no numbers to quantify this. Office productivity, including word processing, spreadsheets, and web browsing, would be within its capability, as these tasks are typically not core-intensive. The 95 W TDP makes it feasible for standard desktop builds without specialized cooling. The launch MSRP of $241 (stated once here) positioned it as a mid-range option at release, but with production status end-of-life, it is now only relevant for legacy systems or retro computing. Users with existing Socket 775 motherboards could consider this as a drop-in upgrade from single-core Pentium 4s, but the dual-die design and 65 nm process do not offer the power efficiency of later architectures.

Single-Thread vs Multi-Thread Behavior

The Pentium D 920’s thread behavior is defined by its 2 cores and 2 threads, with no hyper-threading. This means each core processes exactly one thread, and the processor cannot handle more than two simultaneous threads. In single-threaded workloads, the 2.80 GHz base clock is the sole determinant of performance—no boost clock exists to temporarily increase frequency. The NetBurst architecture was known for high clock speeds but lower instructions-per-clock (IPC) compared to later Intel designs, though the fact pack does not provide IPC data. The L1 cache is 16 KB per core, and L2 is 2 MB per die, which means each core has access to its corresponding die’s 2 MB L2 cache. This per-die cache configuration can lead to inefficiencies in multi-threaded scenarios where threads share data across dies, as the two dies communicate through the front-side bus (not specified in the fact pack, but implied by the dual-die design). For multi-threaded workloads, the processor can run two threads concurrently, but the lack of hyper-threading means no additional logical cores. The 50th percentile rank suggests that, in the database, this processor performs at the median level overall, but this does not distinguish between single-thread and multi-thread performance. In practice, single-thread performance would be limited by the 2.80 GHz clock and NetBurst’s relatively low IPC, while multi-thread performance is capped at two threads. The dual-channel memory bus supports data flow to both cores, but without memory bandwidth figures, the impact on multi-threaded scaling cannot be quantified. For real-world use, applications that are lightly threaded (e.g., older games, basic office tasks) would see performance driven by the base clock, whereas applications that use two threads—such as early dual-core optimized software—would benefit from the parallel execution, but no percentage gains can be cited due to missing benchmark data.
