Intel Pentium Dual-Core E2140

The Intel Pentium Dual-Core E2140 is an end-of-life desktop processor from Intel, released on 2007-06-02 and built around the Core 2 architecture with the Allendale codename. The database lists it as a 65 nm part fabricated by Intel, with 105 million transistors on a 77 mm² die. It has two cores and two threads, a 1600.00 base clock, and no boost clock, and it is packaged for the Intel Socket 775 platform. The generation field labels it Pentium Dual-Core (Allendale), and its launch MSRP was $74.

Benchmark Performance

The fact set for the E2140 contains no individual benchmark scores: the benchmarks array is empty and the average benchmark score is recorded as 0. The only ranking information is percentileVsAllCpus, which is 50. That places the processor at the midpoint of the all-CPU distribution in the database, meaning 50 percent of recorded CPUs sit above it and 50 percent sit below it. The nearestRivals field is also empty, so there are no rival names, no rival scores, and no deltaPct values with which to quantify a percentage lead or deficit. Without those entries, the database cannot support statements such as “x percent faster than rival Y” or “x percent slower than rival Z.” The practical consequence is that benchmark-based analysis for this E2140 is limited to the aggregate percentile rather than workload-specific scores.

Even that aggregate is thin: an average benchmark score of 0 carries no workload context, so it should not be read as a real measured performance value. The data does not indicate how the processor behaves in any single application. This means the 50th percentile cannot be tied back to a particular rendering test, compression test, or game test. The useful information is structural: the E2140 is positioned exactly in the middle of the database’s CPU ranking, and no direct competitor deltas are available to refine that picture.

Who Should Consider It

Because no workload benchmarks are recorded, any recommendation has to be inferred from the specification table. The E2140 has two physical cores and two threads, so the operating system will see exactly two logical processors. The base clock is 1600.00, and there is no boost clock, so those two threads run at one fixed frequency under sustained load. That points toward lightly threaded desktop applications rather than heavily parallel workloads. The 1 MB shared L2 cache and 64 KB per-core L1 cache are consistent with a modest desktop processor.

The market segment is listed as Desktop, so the intended deployment is a desktop system. The processor is also end-of-life, which means it is not a candidate for a new high-end build. For workloads that require many threads, the two-thread ceiling is the dominant constraint: there are no extra logical threads, no higher dynamic frequency listed, and no measured multi-core scores to suggest scaling beyond two threads. For basic desktop tasks that rely on a single thread or two threads, the fixed 1600.00 base clock and shared L2 cache define the available performance. The absence of benchmark data means the recommendation is qualitative, but the specification table is enough to show that this is not a many-core part and should be considered only for lightly threaded duties.

Platform and Compatibility

The E2140 uses Intel Socket 775 and belongs to the Core 2 architecture family. Memory support in the fact pack is listed as DDR1, DDR2, and DDR3 over a dual-channel memory bus. The actual memory type used in a system depends on the motherboard, since the listed support spans three different memory generations. ECC memory is not supported: the eccMemory field is false, so error-correcting memory is unavailable. The PCIe interface is Gen 2, which is the listed I/O generation for this platform.

Integrated graphics are described as a chipset feature available on certain motherboards, rather than a guaranteed on-die graphics unit. A board with that chipset feature would be required for display output without a discrete video card. The multiplier is locked, because multiplierUnlocked is false, meaning the CPU multiplier cannot be changed in normal operation. Production status is end-of-life, so the platform is no longer being manufactured. The upgrade path is constrained by these facts: the end-of-life status and the Socket 775 interface limit long-term platform growth, and the data does not list other socket-compatible processors, so no direct upgrade recommendation can be made.

FAQ

Q: How many cores and threads does the E2140 have?

A: It has two cores and two threads, so it presents exactly two logical processors to the operating system.

Q: Does the E2140 support ECC memory?

A: No. The ECC memory field is false.

Q: What memory types are listed for this processor?

A: The memory support field lists DDR1, DDR2, and DDR3, with a dual-channel memory bus.

Q: Is the multiplier unlocked?

A: No. The multiplierUnlocked field is false.

Q: Does the E2140 have integrated graphics?

A: Integrated graphics are listed as a chipset feature available on certain motherboards; the CPU is not described with a guaranteed on-die graphics unit.

Q: Is the E2140 still in production?

A: No. The production status is end-of-life.

Power and Thermals

The E2140 has a TDP of 65, which is the thermal design power listed in the data. The process node is 65 nm, and the die contains 105 million transistors on a 77 mm² die. These physical characteristics, together with the 1600.00 base clock and the absence of a boost clock, define the thermal envelope. A cooling solution appropriate for a 65 TDP desktop processor is implied, although the fact pack does not specify a particular cooler size or model.

The 65 nm process is an older fabrication feature, and the transistor count and die size are fixed design attributes. With no boost clock present, the processor does not have a separate higher-frequency state in the data, so sustained operation is tied to the listed 1600.00 base clock. No other wattage figures appear in the fact pack, so load-specific power draw cannot be estimated beyond the 65 TDP value. The thermal story is therefore straightforward: the data provides a single thermal class and no extra power measurements.

Single-Thread vs Multi-Thread Behavior

The E2140’s execution resources are two cores and two threads. There is no additional logical thread per core in the data, so each core contributes exactly one thread. A single-threaded workload has one core available, and because the base clock is 1600.00 with no boost clock, that thread runs at the listed frequency under sustained load. A multithreaded workload can use two threads, but no more than two. The shared 1 MB L2 cache is common to both cores, while each core has 64 KB of L1 cache.

The data does not include per-thread benchmark results, so the practical ratio between single-thread and multi-thread performance cannot be quantified. The structural implication is clear: workloads that split into exactly two threads can use the full CPU, while workloads expecting more than two threads will leave processing capacity unused. The lack of a boost clock reinforces a steady, non-bursty single-thread profile. This is a fixed-frequency, two-thread processor, and every real-world workload must fit within that boundary.

How It Compares

The nearestRivals array for the E2140 is empty. As a result, there are no rival names, no rival scores, and no deltaPct values to describe how this processor compares against specific competitors. The only comparative data point is the database-wide percentileVsAllCpus of 50, which indicates a midpoint ranking. In the absence of nearest-rival entries, no percentage lead or deficit can be stated. There are no rival-specific paragraphs to write because the fact pack contains no rivals for this part.
