Intel Core Duo T2600

The Intel Core Duo T2600 is a dual-core mobile processor from Intel’s Core generation, built on the Yonah architecture. It runs at a fixed 2.17 GHz base clock with no boost capability, carries a 31W TDP, and was released in January 2006. The database records a 50th percentile ranking among all CPUs but an average benchmark score of 0, indicating that no performance measurements have been captured for this part. With two cores, two threads, and a 2MB L2 cache, it represents an early dual-core mobile design that has since reached end-of-life status.

Power and Thermals

The T2600’s 31W TDP places it in a modest power class for a mobile processor of its era. The 65nm process node, combined with a die size of 90mm² and 151 million transistors, defines the thermal envelope. A 31W rating typically allows for a slim cooling solution—adequate for a mainstream notebook chassis but not for fanless designs. Since the processor lacks a boost clock, power draw remains consistent under sustained load, avoiding the transient spikes seen in later turbo-enabled parts. The integrated graphics are not on the CPU die but are instead a chipset feature, meaning the processor itself does not generate additional GPU heat. This separation simplifies thermal management for the CPU package, though the overall system still relies on the chipset for display output. The end-of-life status suggests that no new cooling designs are being developed for this TDP class, but the 31W figure remains a reference point for comparable legacy mobile processors. In practice, a capable air cooler—such as a small heatpipe assembly—would suffice, though the exact cooler specifications are not provided in the database.

Single-Thread vs Multi-Thread Behavior

With two cores and two threads, the T2600 offers no simultaneous multithreading; each core executes a single thread. The base clock of 2.17 GHz is the maximum operating frequency, as no boost clock is available. This fixed frequency means that single-threaded performance is determined solely by the core architecture and that clock rate. The cache hierarchy includes 64KB of L1 and 2MB of L2, which helps reduce memory latency for frequently accessed data. For single-threaded workloads—such as legacy office applications or older games—the processor relies on its per-core throughput and cache efficiency. The absence of a boost mechanism means that bursty workloads cannot temporarily increase frequency, so performance is consistent but not adaptive.

Multi-threaded behavior is limited to two concurrent threads. This is sufficient for dual-threaded applications, but it cannot scale beyond that. The 2.17 GHz clock applies to both cores simultaneously, so multi-threaded performance scales roughly linearly up to two threads, assuming the workload is parallelizable. However, the lack of hyper-threading means that even a single core cannot handle two logical threads, which limits context-switching efficiency in mixed workloads. The 2MB L2 cache is shared between the two cores, which can create contention if both cores are accessing the same data set. For the era, this dual-core configuration was a significant step up from single-core mobile parts, but it remains a basic implementation by modern standards. The single-thread vs. multi-thread split is typical of early dual-core processors: strong enough for mainstream productivity, but not designed for heavy parallel processing.

Benchmark Performance

The database lists an average benchmark score of 0 for the T2600. This is an unusual figure, likely indicating that no benchmark runs have been submitted or recorded for this processor. The 50th percentile ranking, however, places it exactly in the middle of the distribution of all CPUs tracked by the database. This median position suggests that, were the processor to be benchmarked, it would likely perform at a level comparable to the midpoint of all processors—though the lack of actual scores makes this speculative. The zero score is not a measure of performance; rather, it reflects the absence of data. For a processor released in January 2006, this is not surprising, as modern benchmarking suites rarely cover such old hardware. Without benchmark results, no direct performance deltas can be calculated against any rivals. The database’s nearestRivals array is empty, so no comparative scores or percentage differences are available. The 50th percentile is the only positional metric, and it must be interpreted cautiously given the missing benchmark data. In essence, the T2600’s performance cannot be quantified from the provided facts, and any assessment must rely on its architectural specifications and clock rate.

How It Compares

The database does not list any nearest rivals for the Intel Core Duo T2600. The nearestRivals field is empty, meaning there are no competitor processors with recorded scores to compare against. This absence of comparative data prevents any percentage-based analysis or ranking within a peer group. The only global reference is the 50th percentile among all CPUs, which places the T2600 in the middle of the entire distribution. However, because the average benchmark score is zero, that percentile is not backed by concrete measurements. In the absence of rivals, the processor’s position can only be described qualitatively: it is a dual-core mobile chip from 2006, with a 2.17 GHz clock and a 31W TDP, which would have placed it in the mainstream laptop segment of its time. Without rival data, any further comparison is impossible. The lack of nearest rivals may also reflect the processor’s age and limited presence in the database. For a hardware analyst, this means the T2600 cannot be positioned against contemporaries like other Core Duo variants or competing AMD mobile chips, as those are not listed. The database simply does not contain the necessary information for a comparative evaluation.

Platform and Compatibility

The T2600 is designed for Intel Socket 479, a socket used in many mobile platforms of the mid-2000s. It supports DDR1 memory, an older DRAM standard that offers lower bandwidth compared to later DDR2 and DDR3 generations. The processor does not list a PCIe configuration, so all PCIe connectivity is provided through the motherboard’s chipset rather than the CPU itself. The integrated graphics are also a chipset feature, meaning the processor relies on an external GPU or the chipset’s integrated video for display output. The architecture is Intel’s Core, with the codename Yonah, fabricated on a 65nm process at Intel’s foundry. The transistor count is 151 million, and the die size is 90mm². The processor is not multiplier-unlocked, so overclocking is not supported. The part numbers are SL8VN and SL9JN. The release date is January 4, 2006, and the production status is end-of-life, indicating that the processor is no longer manufactured. For upgrade paths, the socket 479 is specific to this generation; later Intel mobile processors moved to different sockets, so upgrading from the T2600 would require a new motherboard. The memory support is limited to DDR1, which further constrains system upgrades. The lack of ECC memory support is also noted. Overall, the platform is a legacy mobile design, with no forward compatibility. The chipset’s role in providing graphics and PCIe means that the CPU’s integration is minimal, a contrast to later processors that included memory controllers and PCIe lanes on-die. The 2MB L2 cache and 64KB L1 cache are the only cache levels listed; no L3 cache is present. The processor’s market segment is mobile, and its 31W TDP aligns with that classification. For a modern perspective, the T2600 is a historical artifact, but its specifications provide a clear picture of early dual-core mobile computing.
