Intel Core 2 Duo T7400

The Intel Core 2 Duo T7400 is a mobile processor built on the 65 nm Core 2 (Merom) architecture, featuring 2 cores and 2 threads with a base clock of 2.17 GHz. It carries a 35 W TDP, places in the 50th percentile of all CPUs in the database, and is an end-of-life part for the Intel Socket 479 platform.

How It Compares

The T7400’s benchmark database entry lists no nearest rivals, so direct comparative analysis against specific competing parts is unavailable from the data. Its 50th percentile ranking places it exactly at the midpoint of all CPUs tracked, meaning half of the processors in the database score higher and half score lower. This is a neutral position—neither a standout performer nor a laggard in the broader CPU landscape.

Without nearestRivals data, the T7400’s standing must be inferred from its architectural traits rather than head-to-head scores. As a dual-core, dual-thread part from the Merom generation, it occupies a distinct segment of mobile computing from that era. The lack of rival entries does not imply the chip is without competition; rather, the database has not assigned specific comparison points for this processor.

Power and Thermals

The T7400 is rated at a 35 W TDP, which places it in the low-power mobile class. For a 65 nm part, this TDP suggests a cooling solution that is modest by modern standards—a small heatpipe or thin fan assembly typical of laptops from its release period would suffice. The data indicates this is a mobile processor, so the thermal design targets sustained operation in a chassis with limited airflow.

A 35 W TDP implies the chip can be handled by a basic notebook cooler, not a high-end tower air cooler or liquid setup. In practical terms, builders or users servicing a laptop with this CPU should expect heat output that a standard mobile heatsink can dissipate without throttling under normal loads. The absence of a boost clock in the data means the processor runs at a fixed 2.17 GHz, which simplifies thermal behavior—there is no turbo state to spike heat output.

Single-Thread vs Multi-Thread Behavior

The T7400 offers 2 cores and 2 threads, meaning no hyper-threading. This yields a 1:1 ratio of threads to cores, which is the simplest possible execution model. Single-threaded performance is driven entirely by the 2.17 GHz base clock and the Core 2 architecture’s IPC (instructions per clock). The data does not provide separate single-thread or multi-thread benchmark scores, so the split must be reasoned from the core/thread configuration.

For real workloads, this means the T7400 handles single-threaded tasks—like older games, basic office applications, or legacy software—with a predictable performance level tied to its clock speed. Multi-threaded workloads, however, will only utilize two threads, so any application that scales beyond two threads will see limited benefit. A modern 4-core or 8-core processor would outperform it in parallel tasks, but the data shows the T7400’s 50th percentile ranking, which reflects its aggregate standing across all benchmark types.

The L2 cache is 4 MB, which is shared between the two cores. This is a meaningful asset for multi-threaded workloads that access shared data, as the cache reduces memory latency. However, with only 2 threads, the cache’s advantage is capped—there are no additional threads to exploit temporal locality beyond the two cores.

FAQ

A: The release date is 2006-07-26.

Q: How much L2 cache does the T7400 have?

A: It has 4 MB of L2 cache, with 64 KB of L1 cache.

Benchmark Performance

The T7400’s average benchmark score is 0, and its percentile rank is 50. This combination indicates that the processor has no recorded benchmark scores in the database, yet it still occupies the median position. This is an unusual data point—a zero score typically means no tests have been run, but the percentile assignment suggests a statistical placement rather than a measured result.

Without nearestRivals data, there are no deltaPct values to report against specific competitors. The fact pack provides no rival names, scores, or percentage deltas, so any exact comparative performance figures are absent. The 50th percentile is the only quantitative comparison available: it sits precisely at the midpoint of all CPUs, implying that in the database’s ranking model, half of all processors are slower and half are faster.

For context, a processor from the same era with a higher clock speed or more cores would likely rank higher, but the data does not specify such rivals. The T7400’s 2.17 GHz clock, 2 cores, and 4 MB cache define its theoretical capability, but without measured scores, benchmark performance cannot be quantified beyond the percentile. The zero average score suggests the chip has not been subjected to the database’s standard test suite, so its true performance remains unverified.

Platform and Compatibility

The T7400 is built for Intel Socket 479, a mobile socket that was prevalent in laptops from the mid-2000s. The chip’s architecture is Core 2, with the codename Merom, and it belongs to the Core 2 Duo (Merom) generation. The process node is 65 nm, with 293 million transistors on a 143 mm² die size.

Memory support is not listed in the fact pack, meaning the data does not specify DDR2 or DDR3 compatibility, memory bus width, or bandwidth. ECC memory is explicitly unsupported. The processor has no PCIe information provided, so the interface generation and lane count are unknown from the data. Integrated graphics are noted as a chipset feature on certain motherboards, indicating that the CPU itself lacks an iGPU—graphics output would depend on a discrete GPU or a motherboard with built-in graphics capability.

The market segment is mobile, and the production status is end-of-life, meaning the chip is no longer manufactured. The part number is SL9SK. The T7400 is not multiplier-unlocked, so overclocking is not possible via the CPU multiplier. The socket 479 platform was a mainstream mobile standard of its time, so the T7400 would fit into laptops designed for that socket, but the end-of-life status means upgrade paths are limited to used or refurbished parts. Given the 2006 release date, the platform is legacy, and modern compatibility is nonexistent—a user would need a motherboard from that era to install this CPU.
