Intel Core 2 Duo E8800

The Intel Core 2 Duo E8800 is an end-of-life desktop processor from Intel, built on the 45 nm Wolfdale implementation of the Core 2 architecture. It has 2 cores and 2 threads at a 3.67 GHz base clock with no boost clock listed. The chip carries 410 million transistors on a 107 mm² die and is rated at a 65 W TDP. It fits Intel Socket 775, and the record lists the part number QKJK.

Single-Thread vs Multi-Thread Behavior

The E8800’s execution resources are 2 cores and 2 threads. That ratio means each core handles one thread; there is no extra thread context per core in the data. A single-threaded workload will use one core, and the remaining core can be used by another thread. A workload with more than two threads will queue on those two cores, because the processor cannot provide more than two concurrent threads.

The base clock is 3.67 GHz and no boost clock is recorded. This makes the 3.67 GHz figure the only clock state in the data. For single-thread response, the relevant facts are this clock, the 64 KB L1 per core, and the 6 MB shared L2. When one core is active, it can draw on its own 64 KB L1 and the shared 6 MB L2. The L3 field is null, so no L3 cache contributes.

For multi-thread behavior, the ceiling is two threads. The dual-channel memory bus is listed, and that helps when two cores are moving data simultaneously. Memory support is DDR1, DDR2, or DDR3 depending on the motherboard, so the memory generation is not fixed by the processor itself. The overall percentileVsAllCpus value of 50 places the processor at the median of the CPUs in the database, which is a global rank rather than a single-thread or multi-thread score. The data does not include a separate single-thread or multi-thread benchmark, so the split between them has to be understood from the core and thread count.

Power and Thermals

The TDP is 65 W, which is the only power figure in the record. The processor is a 45 nm Intel part with 410 million transistors and a 107 mm² die. Those three items — process node, transistor count, and die area — are the physical context for the thermal envelope. No cooler size or measured temperature is listed in the fact pack, so the cooling tier must be estimated from the 65 W TDP class rather than from a specific cooler requirement.

The absence of a boost clock also simplifies the thermal picture: the processor does not have a second, higher frequency state in the data to push power above the base 3.67 GHz state. The integrated graphics are described as a chipset feature on certain motherboards, not as a CPU block, so graphics power is not included in the processor’s thermal description. ECC memory is not supported, which is a compatibility fact rather than a thermal one, but it matters when choosing a board for a 65 W build. Production status is end-of-life, so the data does not indicate current availability of new factory units.

Benchmark Performance

The benchmark portion of this record is empty. The benchmarks array contains no entries, the average benchmark score is 0, and nearestRivals is empty. Because nearestRivals has no entries, there are no rival names, no rival scores, and no deltaPct values to cite. It is therefore not possible to write an exact percentage comparison such as “the E8800 is X% faster than…” from this data.

What the data does provide is the percentileVsAllCpus value of 50. That places the E8800 exactly at the median of all CPUs in the database. A median percentile is a meaningful anchor: half the database population ranks above it and half below, in the database’s current distribution. However, the 0 average benchmark score should not be read as a measured zero in a specific test; it simply reflects the empty benchmarks array. No workload-specific scores are present, so gaming, rendering, or office application performance cannot be quantified.

With no rival scores, the performance discussion falls back to structural figures: 2 cores, 2 threads, 3.67 GHz, 6 MB shared L2, dual-channel memory, PCIe Gen 2, and a 65 W TDP. These are the parameters that would influence real performance in the absence of direct benchmark data. The L3 cache field is null, and memory bandwidth is also null, so cache-depth and memory-bandwidth effects are not documented. The 50th percentile is the only direct comparative metric in the record, and the empty nearestRivals list means no deltaPct statement can be made.

FAQ

Q: How many cores and threads does the Core 2 Duo E8800 have?

A: It has 2 cores and 2 threads. Since cores and threads are equal, the processor provides one thread per core.

Q: What clock speed is listed?

A: The base clock is 3.67 GHz. No boost clock is present in the data, so there is no higher frequency state recorded.

Q: What is the TDP?

A: The TDP is 65 W.

Q: What socket does the E8800 use?

A: Intel Socket 775. The part number in the record is QKJK.

Q: What memory support is listed?

A: DDR1, DDR2, and DDR3 are listed as supported, depending on the motherboard. The memory bus is dual-channel.

Q: Is the multiplier unlocked?

A: No. The multiplierUnlocked field is false, which means the multiplier is locked.

Who Should Consider It

Because the benchmarks array is empty, any purchasing decision has to be made on the structural facts from the record. The processor is a 2-core, 2-thread desktop part with a 3.67 GHz base clock and a 50th-percentile overall rank. That percentile places it in the middle of the database’s CPU population.

A user with a Socket 775 motherboard can consider the E8800 if the motherboard’s memory support matches the DDR1, DDR2, or DDR3 list and the board provides the required chipset features. The dual-channel memory bus is present, so memory-heavy tasks can use two channels if the board supports it. The 6 MB shared L2 is a useful pool for data that is reused across cores, and the per-core 64 KB L1 helps single-thread response.

For gaming, there are no game benchmark scores in the data. The available facts are 2 cores, 2 threads, 3.67 GHz, and PCIe Gen 2. A workload that relies on one or two threads can use the full clock; a workload that needs many threads will not scale beyond two threads.

For creation or productivity, the same ceiling applies. A renderer that uses two threads will see both cores active; a renderer that expects more than two threads will be limited by the two-thread ceiling. The data does not include a multi-core score, so the magnitude of that effect cannot be quantified. The absence of ECC support also means this is not a data set for an ECC memory workstation.

For office-style use, the relevant facts are the 65 W TDP, dual-channel memory bus, and desktop market segment. No office benchmark is in the record, so the office recommendation is limited to general system configuration rather than a specific score. The end-of-life production status means the E8800 is not a current production part. The 50th percentile overall rank is a median position, which is the most direct performance-level signpost the data provides.

Platform and Compatibility

The platform anchor is Intel Socket 775. The E8800 is a desktop part from Intel’s Core 2 architecture, codenamed Wolfdale, built on a 45 nm process. The processor is paired with memory via a dual-channel bus, but the actual memory generation is motherboard-dependent: DDR1, DDR2, and DDR3 are listed, so the CPU can work with any of those memory types if the motherboard provides the corresponding support.

PCIe support is Gen 2. No lane count is recorded, so expansion bandwidth beyond the generation cannot be specified. Integrated graphics are not listed as a CPU feature; the data describes them as available on certain motherboards as a chipset feature. That means display output depends on the motherboard chipset rather than on the processor alone. ECC memory is false, so the platform does not present ECC support in this data.

The multiplier is locked, so the clock multiplier cannot be changed. The base clock is 3.67 GHz and no boost clock is listed, so the operating frequency is tied to the base clock. The production status is end-of-life, and no release date is recorded, so the data does not document when the part launched. The part number is QKJK.

The upgrade path for this processor is governed by the socket and the board. The nearestRivals array is empty, so this record does not document any other processors for a direct comparison or upgrade path. The end-of-life status reinforces that the platform is no longer in active production. The L3 cache is null, and memory bandwidth is null, so the remaining compatibility details are the dual-channel memory bus, PCIe Gen 2, and the 65 W TDP class. The process node, transistor count, and die size complete the physical platform picture: 45 nm, 410 million transistors, and 107 mm².
