Intel Core Duo T2500

The Intel Core Duo T2500 is a dual-core mobile processor from the Core (Yonah) generation, built on a 65 nm process at Intel. It operates at a base clock of 1992 MHz with a 31 W TDP, targeting the Socket 479 mobile platform, and its benchmark data indicates it sits at the 50th percentile among all CPUs, representing a mid-pack position for its era.

Benchmark Performance

The benchmark database lists no direct scores for the Intel Core Duo T2500, with an average benchmark score of zero and no nearest rival entries available for comparison. This absence of data points is itself informative: the processor likely predates the standardized benchmarking suite used for current database entries, or it was not sampled in sufficient quantities to generate a statistically meaningful score. The 50th percentile ranking is a neutral placement, suggesting that when the T2500 was active, it performed neither at the top nor the bottom of the CPU landscape. Without deltaPct values from nearestRivals, a quantitative comparison against specific competitors is not possible. The data shows a chip that was a mainstream dual-core offering, positioned exactly at the median of all CPUs tracked by the database. For users consulting this database, the T2500's performance profile must be inferred from its architectural traits — two cores at roughly 2 GHz — rather than from direct benchmark deltas. The lack of rival scores means no statement can be made about its advantage or deficit relative to contemporaneous parts such as the AMD Turion line or Intel's own Pentium M series. The percentile field, however, places it in the middle of the distribution, which aligns with a mid-range mobile part from early 2006. The benchmark results indicate that the T2500 was not a flagship performer, but it was not a low-end chip either; it occupied the central band of performance, which is consistent with its position in the product stack.

Single-Thread vs Multi-Thread Behavior

The T2500 has 2 cores and 2 threads, meaning it lacks Hyper-Threading, so each core handles exactly one thread. This configuration yields a direct correlation between core count and thread count, with no synthetic multi-threading gains. The base clock of 1992 MHz is the sole frequency reference, as no boost clock exists; the chip runs at a fixed speed under load. For single-threaded workloads, the T2500 relies entirely on its Yonah architecture's instruction efficiency and clock speed. The 2 MB L2 cache is shared between the two cores, which can benefit both single-threaded tasks (by offering a large pool of cached data) and multi-threaded tasks (by allowing both cores to access the same cache without contention penalties). In real-world terms, a dual-core processor without SMT on a 65 nm process will show a near-linear scaling from one thread to two threads for parallelizable workloads, but it will hit a wall beyond two threads. The data shows that for applications that are predominantly single-threaded — such as older games or legacy office software — the T2500's performance is dictated by its 1992 MHz clock and the IPC of the Yonah core. For multi-threaded tasks, the scaling is limited to two threads; any workload expecting more than two concurrent threads will not see additional benefit. The absence of a boost clock means the chip cannot dynamically increase its frequency for short single-thread bursts, so its single-thread performance is fixed. This split suggests that the T2500 was best suited for dual-threaded productivity tasks, like spreadsheet calculations or light video editing, rather than heavily threaded modern applications that expect four or more threads. The 64 KB L1 cache (likely split as 32 KB instruction and 32 KB data per core) further supports moderate single-thread performance, but the lack of an L3 cache means the chip relies on the 2 MB L2 as the last-level cache, which is sufficient for the era but small by today's standards.

Power and Thermals

The T2500 carries a TDP of 31 W, which classifies it as a low-power mobile processor for its time. This TDP figure is a thermal design point, indicating the maximum heat the cooling solution must dissipate under sustained load. A 31 W TDP is modest for a dual-core chip, especially when compared to desktop counterparts that often exceeded 65 W or more. This thermal envelope implies that the T2500 could be cooled by a relatively compact heatsink and fan assembly, typical for thin-and-light laptops of the mid-2000s. The 65 nm process node is the key enabler of this low power draw; the 151 million transistors packed into a 90 mm² die size demonstrate a dense but power-efficient design. The data suggests that the T2500 belongs to a cooling tier that does not require exotic thermal solutions — a standard notebook heatpipe and fan would suffice. The lack of a boost clock also simplifies thermal management, as the chip does not have a high-frequency turbo state that would generate transient heat spikes. For sustained multi-threaded loads, the 31 W TDP means the chip will produce steady, manageable heat; the cooling system needs to handle this continuous output but does not need to accommodate large power swings. The integrated graphics noted as "On certain motherboards (Chipset feature)" is not part of the CPU's thermal load, as it resides on the chipset, so the T2500's own heat generation is solely from the two cores. This thermal profile indicates that the T2500 is suitable for passive or low-noise cooling designs in ultraportable laptops, though a small active fan is more realistic for maintaining performance under load. The 31 W TDP is a critical spec for system integrators, as it directly informs the chassis design and battery life projections; a lower TDP would extend battery life, while a higher one would require heavier cooling.

Who Should Consider It

The Intel Core Duo T2500 is an end-of-life mobile processor, so its consideration set is limited to users of legacy laptops or those seeking replacement parts for vintage systems. For office productivity, the dual-core design at 1992 MHz is adequate for basic tasks like word processing, web browsing with a lightweight browser, and spreadsheet work; the 2 MB L2 cache helps with repetitive office workloads. Gaming is not a strong suit — the lack of a boost clock and the absence of integrated graphics on the CPU (relying on chipset graphics) means the T2500 is not suited for any modern 3D titles, and even contemporary games from its release era would run at low settings and resolutions. Content creation, such as photo editing or encoding, is possible but limited to two threads; simple image manipulation in older software would work, but video rendering would be slow compared to quad-core processors. The 50th percentile ranking indicates a balanced, if unspectacular, performer across the board. The 31 W TDP makes the T2500 a reasonable choice for a secondary or backup laptop where battery life is more important than raw speed, as the low power draw extends runtimes. The socket 479 compatibility means it fits specific motherboards from the 2006-2007 era, so users must verify motherboard support before purchase. The 65 nm process and 151 million transistors are historical markers, not performance features, but they do indicate the chip's place in Intel's roadmap. The lack of ECC memory support and DDR1 memory compatibility further narrow its use to non-critical, consumer workloads. For hobbyists collecting vintage hardware, the T2500 represents a solid dual-core step in Intel's mobile evolution, offering a glimpse of the transition from single-core to dual-core laptops. It is not a processor for anyone seeking modern performance; it is a chip for preservation, basic legacy tasks, or educational purposes about mid-2000s computing.
