About Intel Pentium D 915
The Intel Pentium D 915 is a desktop processor released on July 22, 2006, built on Intel's NetBurst architecture with the Presler codename. It features two cores and two threads, a base clock of 2.80 GHz, and a 95 W thermal design power (TDP). Fabricated on a 65 nm process with 376 million transistors and a dual-die layout (2× 81 mm²), it was positioned as a mid-range dual-core option for mainstream desktop systems. In this database, the Pentium D 915 holds a 50th percentile ranking among all CPUs, placing it exactly at the median of tracked processors, though its average benchmark score is recorded as zero, indicating no performance data is available for direct quantitative comparison.
How It Compares
The Pentium D 915's nearestRivals field is empty, so no direct rival comparisons with named products are possible from the FACT PACK. Instead, its standing is defined by the aggregate percentileVsAllCpus value of 50. This means the processor sits at the exact midpoint of the entire CPU database—half of all tracked processors are faster, and half are slower. This neutral position is consistent with its specifications: two cores and two threads without hyper-threading, a 2.80 GHz base clock, and a 95 W TDP. The lack of any benchmark scores further underscores that no measured performance data exists to refine this ranking.
Within its own architecture, the Pentium D 915 is a dual-core design with no simultaneous multithreading, so it can execute only two threads concurrently. Its 2 MB L2 cache per die (two dies total) provides a moderate cache footprint for its era. The 65 nm process node was a step forward from earlier NetBurst parts, but the architecture itself was known for high power draw relative to competing designs—though the FACT PACK does not provide rival data to substantiate that claim. In the absence of direct comparisons, the percentile ranking serves as the only comparative metric, and it places this CPU in the middle of the pack, neither a performance leader nor a laggard.
Power and Thermals
The Pentium D 915 has a specified TDP of 95 W, which defines its maximum thermal output under typical sustained workloads. This TDP class dictates that the processor requires a cooling solution capable of dissipating 95 W of heat. For a desktop CPU of its generation, a standard air cooler with a 92 mm or larger fan would be adequate, though the FACT PACK does not specify cooler dimensions or types. The 65 nm manufacturing process helps moderate power consumption relative to older 90 nm NetBurst parts, but the dual-die design (two separate 81 mm² dies) means each die contributes to the overall thermal load. The 95 W figure is modest by today's standards but was typical for dual-core processors in 2006.
The absence of a boost clock and the fixed multiplier (multiplierUnlocked: false) mean the processor runs at a constant 2.80 GHz under load, with no automatic overclocking. This steady clock rate simplifies thermal management, as the heat output remains predictable. For users building a system with this CPU, a capable air cooler—one that can handle 95 W—would be sufficient. Liquid cooling is not required, and the TDP is low enough that even a budget-oriented cooler from that era would suffice, though the FACT PACK does not provide specific cooler recommendations.
Who Should Consider It
Based on its specifications, the Pentium D 915 is best suited for basic office productivity, web browsing, and light multitasking. Its two cores and two threads can handle two concurrent tasks without severe degradation, making it adequate for word processing, spreadsheet work, and email. The 2.80 GHz base clock provides reasonable single-thread performance for older applications that rely on a single core. For gaming, the processor lacks integrated graphics (the FACT PACK notes that graphics are "On certain motherboards (Chipset feature)"), so a discrete GPU is mandatory. Even with a discrete card, the dual-core, dual-thread design would likely bottleneck modern games that require four or more threads, though the FACT PACK does not include gaming benchmark data to confirm this.
For content creation, the Pentium D 915 is not recommended for heavily threaded workloads such as video encoding or 3D rendering, as its two threads limit parallel throughput. However, it could handle light photo editing or audio processing in single-threaded applications. The lack of ECC memory support (eccMemory: false) makes it unsuitable for mission-critical or server environments where data integrity is paramount. The processor's end-of-life status (productionStatus: "End-of-life") means it is no longer manufactured, so it is only relevant for legacy system upgrades or retro builds. Users seeking a modern processor for everyday tasks would be better served by more recent offerings, but the FACT PACK does not provide alternative product names.

Platform and Compatibility
The Pentium D 915 is designed for the Intel Socket 775 (LGA775) platform, which was widely used by Intel desktop processors from 2004 through 2009. The socket supports a range of chipsets from that era, though the FACT PACK does not list specific chipset models. Memory support is flexible: the processor can work with DDR1, DDR2, or DDR3 memory, but the motherboard determines which type is used. The memory bus is dual-channel, enabling increased bandwidth when two identical memory modules are installed. ECC memory is not supported, so the platform is not suited for error-correcting workloads.
The processor does not include a PCIe controller, and the FACT PACK does not provide any PCIe information. Therefore, PCIe lanes are provided by the motherboard's chipset, which typically offers a standard set of expansion slots for graphics cards and other peripherals. The integrated graphics situation is dependent on the chipset—some motherboards with integrated graphics chipsets can provide display output, but the processor itself has no graphics core. For any graphical output, a discrete GPU is required unless the motherboard includes an integrated graphics solution.
The upgrade path for this socket is limited. Because the Pentium D 915 is end-of-life and the LGA775 platform is obsolete, there are no modern processors available for this socket. Users on this platform would need to replace the entire motherboard and CPU to move to a newer architecture. The processor's part numbers are SL9DA and SL9KB, and its launch MSRP was $74. The multiplier is locked, so overclocking is restricted. The dual-die design (2× 81 mm²) and 376 million transistors reflect the 65 nm manufacturing process, which was Intel's mainstream node at the time of release. Overall, the Pentium D 915 is a legacy part that can serve in basic desktop roles but offers no modern upgrade path.
