Core 2 Duo T9400 Core Configuration
Processing cores and threading
The Intel Core 2 Duo T9400 features 2 physical cores and 2 threads, which directly impacts multi-threaded performance in CPU benchmarks. More cores allow the processor to handle parallel workloads efficiently, improving performance in video editing, 3D rendering, and multitasking scenarios. Thread count determines how many simultaneous tasks the CPU can process, with higher thread counts benefiting productivity applications and content creation workflows.
2 Duo T9400 Clock Speeds
Base and boost frequencies
Clock speed is a critical factor in Core 2 Duo T9400 benchmark performance, measured in GHz. The base clock represents the guaranteed operating frequency, while the boost clock indicates maximum single-core performance under optimal conditions. Higher clock speeds translate to faster single-threaded performance, which is essential for gaming and applications that don't fully utilize multiple cores. The Core 2 Duo T9400 by Intel can dynamically adjust its frequency based on workload and thermal headroom.
Intel's Core 2 Duo T9400 Cache Hierarchy
L1, L2, L3 cache sizes
Cache memory is ultra-fast storage built directly into the 2 Duo T9400 processor die. L1 cache provides the fastest access for frequently used data, while L2 and L3 caches offer progressively larger storage with slightly higher latency. Larger cache sizes significantly improve CPU benchmark scores by reducing memory access times. The Core 2 Duo T9400's cache configuration is optimized for both gaming performance and productivity workloads, minimizing data fetch delays during intensive computations.
Core 2 Architecture & Process
Manufacturing and design details
The Intel Core 2 Duo T9400 is built on Intel's 45 nm manufacturing process, which determines power efficiency and thermal characteristics. Smaller process nodes allow for more transistors in the same space, enabling higher performance per watt. The architecture defines how the processor handles instructions and manages data flow, directly impacting benchmark results across different workload types. Modern CPU architectures like the one in 2 Duo T9400 incorporate advanced branch prediction and out-of-order execution for optimal performance.

About Intel Core 2 Duo T9400
The Intel Core 2 Duo T9400 is a mobile processor with 2 cores and 2 threads, running at a 2.53 GHz base clock with no boost clock listed. It belongs to the Core 2 architecture with the codename Penryn, and its generation is listed as Core 2 Duo (Penryn). The release date in the data is 2008-07-14, and the production status is end-of-life. The FACT PACK contains no benchmark entries, an average benchmark score of 0, and a 50th percentile rank among all CPUs, so the database provides no measured workload performance for this part.
Who Should Consider It
The benchmark list for this processor is empty. That means the data cannot directly recommend it for gaming, creation, or office workloads based on measured scores. What the data does show is a hard thread ceiling: 2 cores and 2 threads. Any workload that fits inside that dual-thread envelope is the realistic candidate. Workloads that expect more than two concurrent threads will have no additional logical processors to use on this part.
The only frequency in the data is the 2.53 GHz base clock. There is no boost clock listed, so the processor has no burst frequency headroom to improve responsiveness when a single thread is active. For single-threaded tasks, the 2.53 GHz clock is the relevant performance anchor. For multi-threaded tasks, the limit is two threads, regardless of the clock speed.
Because the market segment is Mobile and the production status is End-of-life, this processor is not positioned as a current high-end part. It is better suited to legacy systems or specific mobile applications that use Intel Socket P and can operate within the dual-thread constraint. The database does not provide measured scores for rendering, encoding, or other creation-style workloads, so there is no evidence in the data to support a recommendation for those uses. The launch MSRP was $316.
The 50th percentile rank places it in the middle of the CPU database, but the average benchmark score of 0 indicates that no measured samples back that percentile. In practical terms, the data shows a processor whose thread topology defines its applicability more clearly than any performance number. A two-thread processor with a 2.53 GHz base clock is not a match for tasks that scale across many threads. It is a match for tasks that use one or two threads and for platforms that require this specific mobile socket.
Power and Thermals
The TDP listed for the T9400 is 35. That is a low thermal class, which implies a modest cooling solution. The data does not specify a cooler size or cooler tier, but a 35 TDP mobile part does not suggest high-end desktop cooling. The absence of a boost clock also means there is no extra burst frequency that would complicate thermal behavior.
The manufacturing process is 45 nm, and the foundry is Intel. The die contains 410 million transistors on a 107 mm² die. Those figures describe a compact chip physically. The data does not list temperatures, cooling requirements, or thermal headroom, so the only quantified thermal specification is the 35 TDP itself.
For a mobile processor, a 35 TDP rating implies the cooling solution can be relatively small. The data does not name any cooler, but the combination of a mobile market segment and a 35 TDP rating points toward a low-power thermal envelope. The process node is 45 nm, which is older relative to more recent data in the database, but the FACT PACK does not state any thermal consequence of that process size.
Single-Thread vs Multi-Thread Behavior
The T9400 has 2 cores and 2 threads. There is one thread per core, so the data shows no simultaneous multithreading. The base clock is 2.53 GHz, and no boost clock is listed. That makes 2.53 GHz the only operating frequency in the data.
The cache layout is split between per-core and shared storage. L1 cache is 64 KB per core, while L2 cache is 6 MB shared. No L3 cache is listed in the data. The shared L2 means both cores have access to a common 6 MB cache, but the data does not quantify cache bandwidth or latency, so the practical impact of that shared cache cannot be measured from the FACT PACK.
For single-threaded workloads, the data shows a 2.53 GHz core and access to the shared 6 MB L2. For multi-threaded workloads, the data shows a hard limit of two threads. Any application that wants more than two logical processors will not find them here. Because the benchmark score is 0 and the benchmark list is empty, there is no measured split between single-thread and multi-thread performance. The structural split is clear: 2 cores, 2 threads, one frequency, and a shared L2.
FAQ
Q: Does the Core 2 Duo T9400 have integrated graphics?

A: No boost clock is listed. The only frequency in the data is the 2.53 GHz base clock.
Q: Is this processor still in production?
A: No. The production status is end-of-life, and the release date is 2008-07-14.
Q: What socket does it use?
A: The processor uses Intel Socket P.
How It Compares
The nearestRivals array in the FACT PACK is empty. There are no rival names, scores, or deltaPct values to present. As a result, the T9400 cannot be positioned against specific competing processors using this data. The only relative ranking available is the 50th percentile among all CPUs, alongside an average benchmark score of 0. Without nearest rival entries, any direct statement such as "ahead of" or "behind" a specific competitor would be unsupported by the data.
Platform and Compatibility
The processor is listed for Intel Socket P. Memory support includes DDR2 and DDR3, using a dual-channel memory bus. ECC memory is not supported. The data does not include a PCIe specification; the pcie field is null, so no lane count or version is stated.
The integrated graphics field is "On certain motherboards (Chipset feature)", meaning the chipset provides graphics on certain motherboards. The multiplier is not unlocked, so the data shows no unlocked ratio adjustment. The production status is end-of-life, with a release date of 2008-07-14. The listed part number is QAELQHBJSLB46SLGE5.
The data does not specify compatible chipsets, motherboard models, or successor processors. The only socket listed is Intel Socket P, and the only memory types listed are DDR2 and DDR3. No memory bandwidth figure is provided, and no L3 cache is listed. A concrete upgrade path cannot be established from the data; any platform decision should respect the listed socket, memory types, and end-of-life status.
