Intel Core i3-4100E

The Intel Core i3-4100E is a dual-core Haswell mobile processor from 2013, built on Intel's 22 nm process with 1,400 million transistors and a die size of 118 mm². It operates at a fixed 2.40 GHz base clock with no boost capability, paired with 3 MB of shared L3 cache and an integrated Intel HD 4600 GPU. Its benchmark data places it firmly in the entry-level segment, with a 10th percentile ranking among all CPUs and an average benchmark score of 540.

Benchmark Performance

The Core i3-4100E delivers modest multi-core performance that scales predictably across Cinebench versions. Its Cinebench R15 multi-core score of 158 and R20 multi-core score of 659 translate to a Cinebench R23 multi-core result of 1570, showing consistent rendering capability for a dual-core part. In single-core workloads, the R20 score of 92 and R23 score of 221 indicate the processor's limited per-thread throughput, a direct consequence of its locked 2.40 GHz clock and lack of Turbo Boost.

Relative to its nearest rivals, the i3-4100E sits in a tight performance cluster. It edges out the Intel Core i3-2310E by just 0.1% in average benchmark score (540 vs 539), making the two effectively identical in overall performance despite the architectural gap between Haswell and Sandy Bridge. Against the AMD Phenom II X3 B77, the i3-4100E is 0.2% faster, a negligible margin that underscores how close these older parts are in aggregate compute. The picture flips slightly when compared to the Intel Xeon L5410 and Intel Core i3-2100, both of which post average scores of 542, putting them 0.3% and 0.4% ahead of the i3-4100E, respectively. These deltas are within run-to-run variance, meaning the i3-4100E effectively trades blows with all four rivals.

The 10th percentile standing among all CPUs indicates that this processor is outclassed by roughly 90% of the market, even accounting for its mobile-oriented design. In practical terms, the Cinebench R23 multi-core score of 1570 places it well below modern desktop quad-cores, but the numbers must be read in context: this is a low-power mobile chip intended for compact or embedded systems, not a performance flagship. The average benchmark score of 540 aligns closely with the rival cluster, confirming that its position is defined more by generation parity than by any standout strength.

Power and Thermals

The i3-4100E carries a 37 W TDP, a figure that places it in the efficient mid-range of mobile processors for its era. This TDP class implies that a modest cooling solution, such as a small active fan or a compact heatpipe assembly, is sufficient for sustained operation. The 22 nm process node helps keep thermals manageable, and the absence of a boost clock means power draw remains steady under load rather than spiking during turbo windows.

For system integrators, the 37 W envelope allows for thin-and-light laptop chassis or fanless mini-PC designs with adequate airflow. The processor's mobile market segment and Intel BGA 1364 socket further indicate that it is soldered directly to the motherboard, eliminating the need for a socketed cooler and reducing overall system height. This thermal profile is a clear advantage over the rival Xeon L5410, which is a server-oriented part, though the data does not specify the Xeon's TDP for direct comparison. The i3-4100E's power characteristics make it suitable for always-on appliances or industrial PCs where heat dissipation is a primary design constraint.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread scores reveals a processor that is better suited to parallelizable tasks than to latency-sensitive workloads. In Cinebench R23, the multi-core score of 1570 is 7.1 times the single-core score of 221, indicating that both physical cores and Hyper-Threading are being utilized effectively under full load. This scaling is typical for a dual-core, four-thread part, but the absolute single-core figure of 221 is low by modern standards, limiting responsiveness in applications that rely on a single primary thread.

For real-world usage, this means the i3-4100E will handle multi-threaded rendering or batch processing with reasonable efficiency relative to its class, but will struggle with lightly threaded tasks like spreadsheet recalculation or web browsing with heavy JavaScript. The R20 single-core score of 92 reinforces this: it is roughly 14% of the R20 multi-core score of 659, a ratio that suggests the processor's threading overhead is minimal but its per-core IPC is constrained by the 2.40 GHz clock. The lack of a boost clock is particularly impactful here, rival parts with higher turbo frequencies would pull ahead in single-threaded scenarios, though the nearest rivals in the data do not list their clock speeds, so no direct frequency comparison can be made.

Who Should Consider It

The i3-4100E is best suited for workloads that emphasize multi-threaded throughput over single-thread speed, given its 4-thread scaling and modest per-core performance. For basic office productivity, word processing, email, and spreadsheet work, the processor is adequate, but users should expect noticeable lag in complex documents or large data sets. The 3 MB of shared L3 cache helps with repeated data access, but the absence of ECC memory support rules out mission-critical server or error-sensitive workstation deployments.

Content creation tasks that are explicitly multi-threaded, such as video transcoding or 3D scene rendering in Cinebench, will see the i3-4100E perform at a level roughly on par with the competing i3-2310E and Phenom II X3 B77, as evidenced by the near-identical average scores. Gamers should look elsewhere: the integrated HD 4600 graphics and dual-core configuration are not designed for modern titles, and the low single-core scores will bottleneck CPU-bound game logic. The processor is a more logical fit for embedded systems, digital signage, or low-power NAS devices where the 37 W TDP and soldered BGA package simplify thermal and mechanical design.

How It Compares

Intel Core i3-2310E: The i3-4100E is 0.1% faster in average benchmark score (540 vs 539), making the two processors functionally interchangeable in performance. Both are dual-core mobile parts from Intel, but the i3-4100E's Haswell architecture should offer better IPC per clock; the data shows no measurable advantage, likely due to the locked 2.40 GHz clock limiting any architectural gains.

AMD Phenom II X3 B77: This triple-core AMD chip posts an average score of 539, putting the i3-4100E 0.2% ahead. The Phenom's extra physical core is offset by its older architecture and likely lower clock efficiency, resulting in a statistical tie. The i3-4100E's 4 threads, via Hyper-Threading, help it match the Phenom's three native cores in aggregate throughput.

Intel Xeon L5410: The Xeon L5410 leads the i3-4100E by 0.3% with an average score of 542. This server-oriented Xeon, despite being an older generation, edges out the mobile i3 in raw compute. The i3-4100E's lower TDP and integrated graphics give it an efficiency advantage in compact systems, but the Xeon retains a slight performance lead in multi-threaded server workloads.

Intel Core i3-2100: The desktop i3-2100 averages 542, which is 0.4% higher than the i3-4100E's 540. This is the largest delta among the rival set, yet still negligible in real-world terms. The i3-2100's higher base clock, likely above 2.40 GHz, explains the edge, though the i3-4100E compensates with a newer architecture and lower power draw. Both are dual-core with Hyper-Threading, so the performance gap is confined to clock speed differences.
