Intel Core Duo T2400

The Intel Core Duo T2400 is a 2-core, 2-thread mobile processor from Intel’s Core architecture, built on a 65 nm process with a 31 W TDP and a base clock of 1826.00 MHz. It targets the mobile segment, was released in early 2006, and is now end-of-life, holding a 50th percentile ranking among all CPUs in the database.

Who Should Consider It

The T2400’s benchmark profile places it squarely in the entry-level mobile territory of its era. With only 2 threads and no boost clock, the data indicates this chip is best suited for basic productivity tasks — word processing, spreadsheet work, and light web browsing — where single-threaded responsiveness matters more than parallel throughput. The 50th percentile ranking suggests it sits at the midpoint of all CPUs, meaning it outperforms half of the database’s entries, but that includes many older or lower-power parts; against any modern processor, it will lag significantly.

For gaming, the T2400 is not a realistic option. The lack of a boost clock and the modest 2 MB L2 cache mean that frame rates in contemporary titles would be constrained by CPU-bound scenes, and the integrated graphics option (available only on certain motherboards as a chipset feature) offers no dedicated GPU muscle. The data shows no dedicated graphics core, so any gaming would rely on motherboard-integrated solutions, which historically were weak for 3D workloads.

Creation workloads — video editing, 3D rendering, or large-scale compilation — are also outside this chip’s comfort zone. Multi-threaded tasks would see the T2400 limited to 2 threads, which is a severe handicap compared to even 4-thread rivals from the same generation. The 2 MB L2 cache helps with data locality, but it cannot compensate for the absence of additional execution resources.

Office and everyday use, however, is where the T2400 can still function. A 2-thread design running at 1826.00 MHz can handle single-document workflows and email without issue. The 31 W TDP also suggests it was designed for thin-and-light laptops where battery life and low heat output were priorities, not peak performance. If a user has legacy software that is single-threaded and does not require modern instruction sets, the T2400 remains adequate.

Power and Thermals

The T2400 carries a 31 W TDP, placing it in a low-power class for mobile processors. This figure indicates that a modest cooling solution — a small heat pipe and low-profile fan, or even a passive heatsink in a well-ventilated chassis — would suffice. The 65 nm process node also implies lower leakage currents compared to earlier 90 nm parts, which helps keep thermals manageable under sustained load.

Benchmark results do not provide direct thermal readings, but the 31 W TDP is a clear signal for system integrators: this chip does not require a high-end cooler. A competent air cooler designed for mobile sockets would handle it without throttling. The lack of a boost clock further reduces thermal spikes, as the CPU never dynamically increases its frequency beyond the base 1826.00 MHz. This makes the T2400 predictable in thermal behavior — it will draw a steady amount of power under load, with no sudden jumps that could overwhelm a weak cooling solution.

For battery life, the 31 W TDP is favorable for its time, but it is not class-leading. The data shows no power management figures beyond the TDP, so exact idle consumption is unknown. However, the Yonah core was designed with mobile efficiency in mind, and the 65 nm process helps. Users should expect moderate heat output during extended workloads, but nothing that would require a bulky cooling assembly.

Single-Thread vs Multi-Thread Behavior

The T2400 has 2 cores and 2 threads, meaning it offers no simultaneous multithreading. This is a critical distinction: each core handles exactly one thread, so the chip’s multi-threaded performance is strictly a function of the two cores running at 1826.00 MHz. In contrast, many rivals from the same era offered 4 threads via Hyper-Threading, which the T2400 lacks.

Single-threaded performance is the T2400’s stronger suit relative to its multi-threaded showing. The base clock of 1826.00 MHz, combined with the 2 MB L2 cache, allows for decent integer and floating-point execution on a single thread. For legacy applications that are not optimized for multiple cores, the T2400 will feel responsive. The 50th percentile ranking reflects this balanced profile, but it does not reveal the split; the data suggests that single-thread tasks would score relatively higher than multi-thread tasks when compared to the broader database.

Multi-threaded behavior is where the T2400 falls behind. Two threads total means that any workload that can use more than two threads will see rapid diminishing returns. For example, a video encoding task that scales across 4 or 8 threads would run at roughly half the speed of a similarly clocked 4-thread chip. The lack of a boost clock also means there is no headroom for short bursts of multi-threaded activity — the CPU runs at one speed, always. This makes the T2400 unsuitable for parallel workloads, even light ones like background compression or multi-tab browsers with heavy JavaScript, which often spawn multiple threads.

In practice, the split means the T2400 behaves like a competent single-core processor with one extra core for occasional assistance. Users who run one demanding application at a time will see acceptable performance; those who multitask heavily or run parallel batch jobs will hit a wall quickly.

Platform and Compatibility

The T2400 uses Intel Socket 479, a mobile-specific socket that was common in laptops from the mid-2000s. It is built on the Yonah core, part of the Core Duo generation, and uses a 65 nm process with 151 million transistors on a 90 mm² die. The chip supports DDR1 memory, which is a significant limitation — DDR1 is slow by modern standards and offers limited bandwidth. The data does not list a memory bus width or bandwidth, so exact throughput numbers are unavailable, but the architecture’s reliance on DDR1 constrains memory-intensive workloads.

PCIe support is not listed in the data, meaning the T2400’s expansion capabilities are unclear from the benchmark database. However, the integrated graphics are noted as a chipset feature, available only on certain motherboards. This suggests that the T2400 itself does not contain a GPU, and any display output depends on the motherboard’s chipset integrating a graphics controller. This is typical for mobile CPUs of that era, where the northbridge handled video output.

The upgrade path for Socket 479 is narrow. The T2400 is end-of-life, and the Yonah core was succeeded by later Core 2 Duo mobile parts that used a different socket (Socket P). Therefore, users cannot swap in a newer processor without changing the motherboard. The 2 MB L2 cache is fixed, and there is no L3 cache, so the memory hierarchy is simple: 64 KB L1 and 2 MB L2. ECC memory is not supported, which aligns with the mobile consumer target. The multiplier is locked, so overclocking is not possible. The part number SL8VQ identifies this specific SKU, but no launch MSRP is provided in the data.

How It Compares

The nearestRivals list in the FACT PACK is empty, so there are no direct comparison scores or deltaPct values to reference. This means the T2400’s position in the database must be interpreted solely through its 50th percentile ranking. That percentile places it exactly at the median of all CPUs, indicating a balanced but unremarkable performance profile.

Without rival data, the comparison must rely on the T2400’s own characteristics. Against a hypothetical 2-thread rival with a similar clock speed, the T2400 would be competitive due to its 2 MB L2 cache and 65 nm efficiency. Against a 4-thread rival, the T2400 would likely lose in multi-threaded benchmarks by a wide margin, but single-threaded scores could be similar if the rival’s clock speed is comparable. The 31 W TDP gives it an efficiency advantage over higher-power desktop parts, but that is irrelevant for a mobile chip.

The 50th percentile also reflects the database’s composition: many low-power embedded and ancient CPUs drag the median down, so the T2400’s midpoint status does not imply it is fast by modern standards. It simply sits in the middle of a large field. For a user comparing this chip to anything released after 2010, the T2400 would be dozens of percentage points behind in multi-threaded tasks, and likely behind in single-threaded tasks as well, given the lack of IPC improvements from newer architectures.

In the absence of direct rival scores, the most honest assessment is that the T2400 is a product of its time — a low-power mobile processor that met the needs of 2006-era laptops but offers nothing for modern workloads. Its 2 threads and 1826.00 MHz base clock define its ceiling, and its 31 W TDP defines its thermal envelope. The data shows no surprises, no hidden strengths, and no reason to seek it out outside of legacy systems.
