Intel Core 2 Duo E6700

The Intel Core 2 Duo E6700 is a dual-core desktop processor from the Core 2 generation, built on the 65 nm Conroe architecture. As an end-of-life part with a 50th percentile standing against all CPUs in the database, its benchmark data positions it as a mid-pack historical component rather than a contemporary performer.

Benchmark Performance

The FACT PACK provides no direct benchmark scores for the E6700, and its `avgBenchmarkScore` is recorded as 0. This absence of measured performance data means the processor’s standing must be inferred from its percentile and architectural attributes. The 50th percentile placement indicates that, within the database’s historical sample, the E6700 sits exactly at the median — half of all recorded CPUs score higher, and half score lower.

Without `nearestRivals` data, no exact percentage deltas can be calculated against competing processors. However, the 2.67 GHz base clock, 4 MB of L2 cache, and dual-core/dual-thread configuration provide a qualitative baseline. The lack of a boost clock means all workloads run at the fixed 2.67 GHz frequency, which was typical for the era’s desktop parts. The 65 nm process node and 291 million transistors on a 143 mm² die suggest a mid-2000s performance tier, where the E6700 would have been positioned as a mainstream dual-core offering.

The benchmark results, or lack thereof, indicate that this processor is not evaluated with modern workloads. Its 50th percentile rank is a static historical marker, not a dynamic measurement. For context, the Core 2 architecture was known for strong per-clock efficiency, but the data provided does not allow for quantified comparisons. The processor’s performance class is best described as adequate for its contemporary software, with the dual-core design handling two threads concurrently.

Power and Thermals

The E6700 carries a 65 W TDP, which places it in the mainstream desktop power envelope for its generation. This TDP figure implies that a capable air cooler, such as a stock cooler bundled with retail boxes or a basic aftermarket tower, would be sufficient for sustained operation. The 65 W rating also suggests that the processor does not demand exotic cooling solutions, high-end liquid loops, or oversized heatsinks — a standard mid-tower case with reasonable airflow would manage thermals adequately.

The 65 nm process node contributes to this modest power draw. Smaller process nodes generally reduce voltage and current leakage, and while 65 nm is large by modern standards, it was competitive for the 2006 timeframe. The die size of 143 mm² and 291 million transistors indicate a moderately complex chip that, at 65 W, balances performance and heat output. The absence of a boost clock further simplifies thermal behavior — the processor operates at a constant 2.67 GHz, avoiding the transient spikes seen in modern turbo-boosting parts.

For cooling tiers, the 65 W TDP falls into the "air cooler friendly" category. Users would not need to budget for high-end cooling accessories. The processor’s thermal profile is predictable, and the data suggests that a stock or entry-level aftermarket cooler would maintain safe temperatures under full load. There is no indication of power-hungry features like integrated graphics drawing additional current, as the E6700 relies on chipset-integrated graphics on certain motherboards rather than an on-die GPU.

How It Compares

The FACT PACK lists no `nearestRivals` entries, so no direct score comparisons or percentage deltas are available. The processor’s 50th percentile rank is the sole positional metric. This places it in a neutral zone — not a standout performer, not a laggard. Against hypothetical contemporaries, one would expect the E6700 to trail higher-clocked or quad-core parts, but the data does not support naming specific rivals or citing their scores.

The Core 2 Duo architecture, with its dual-core and dual-thread design, would face competition from other dual-core processors of the same era. The 2.67 GHz clock is mid-range for the Conroe line, suggesting that higher-clocked siblings or models with larger caches would outperform it. However, without rival names or scores, any such comparison remains speculative. The 4 MB L2 cache is substantial for a dual-core part of that time, which could give it an edge in cache-sensitive workloads versus competitors with smaller caches.

The lack of comparative data means the E6700’s position is defined by its percentile alone. A 50th percentile score indicates that it is an average performer in the database’s historical context — neither a high-end enthusiast part nor a low-end budget chip. This is consistent with its launch MSRP of $316, which positioned it as a mid-range desktop processor, though pricing is noted here only for context.

FAQ

Q: What is the processor’s core and thread count?

A: The Intel Core 2 Duo E6700 has 2 cores and 2 threads, meaning it can process two tasks concurrently without hyper-threading.

Q: Does the E6700 support turbo boosting?

A: No. The processor has a fixed base clock of 2.67 GHz and no boost clock, so it operates at that frequency under all conditions.

Q: What memory types are supported?

A: The E6700 supports DDR1, DDR2, and DDR3 memory, with dual-channel memory bus support. ECC memory is not supported.

Q: Is the processor overclockable?

A: The multiplier is locked, so overclocking would require raising the base clock on the motherboard, which is not guaranteed to be stable.

Q: What is the manufacturing process and die size?

A: The E6700 is built on Intel’s 65 nm process, with 291 million transistors on a 143 mm² die.

Q: What is the processor’s market segment and production status?

A: It is a desktop segment processor that is end-of-life, meaning it is no longer in production and is not recommended for new builds.

Platform and Compatibility

The E6700 uses the Intel Socket 775 interface, which was a long-lived desktop socket. The processor is compatible with the Core 2 architecture and the Conroe codename generation. It supports dual-channel memory with DDR1, DDR2, and DDR3 types, though the actual memory support depends on the motherboard chipset — not all boards will support all three memory generations. The absence of ECC support means it targets consumer and mainstream desktop use rather than server or workstation applications.

PCIe support is listed as Gen 2, which allows for a range of add-in cards, including graphics cards and storage controllers. However, the integrated graphics are not on the CPU; they are a chipset feature on certain motherboards, meaning a discrete GPU is required for display output on boards without integrated graphics. The processor’s memory bus is dual-channel, which provides adequate bandwidth for its era but is limited compared to modern quad-channel or DDR5 platforms.

The upgrade path from the E6700 is constrained by its Socket 775 interface. While the socket supported many generations of Core 2 processors, the motherboard’s chipset determines which CPUs are compatible. The 65 nm process and 291 million transistors are fixed attributes, so the only upgrade option is to replace the processor with a different Socket 775 part, assuming the motherboard’s BIOS and chipset support it. The platform does not support PCIe Gen 4 or newer, nor does it offer modern memory standards like DDR4 or DDR5 — the maximum is DDR3.

Single-Thread vs Multi-Thread Behavior

With 2 cores and 2 threads, the E6700 is a pure dual-core processor without simultaneous multi-threading. This means it can execute two threads at most, which is a significant limitation for modern multi-threaded applications but was standard for desktop CPUs in 2006. The 2.67 GHz base clock applies to both cores equally, and the 4 MB L2 cache is shared between them, allowing for efficient data sharing within a single die.

Single-thread performance is driven by the 2.67 GHz clock and the Core 2 architecture’s efficient execution pipeline. For workloads that rely on one thread — such as older games, basic office tasks, or legacy software — the E6700 would perform adequately for its time. The relatively high clock speed for its generation compensates for the lack of turbo boost, but it cannot match modern processors with far higher clocks and newer microarchitectures.

Multi-thread behavior is limited to two threads, which is the key bottleneck. Any workload that scales beyond two threads will leave the E6700 at a disadvantage, as it cannot allocate additional execution resources. The 50th percentile rank reflects this balance: it is neither a single-thread champion nor a multi-thread workhorse. For dual-threaded tasks, the processor uses its full capacity, but for quad-thread or higher workloads, it falls behind processors with more cores and threads. The absence of a boost clock also means there is no headroom for single-thread bursts, so peak performance is equal to sustained performance.
