Intel Core i3-4330T

The Intel Core i3-4330T is a dual-core, four-thread desktop processor built on Intel’s 22 nm Haswell architecture. It runs at a fixed 3.00 GHz base clock with no turbo, carries 4 MB of shared L3 cache, and integrates Intel HD 4600 graphics. Its average benchmark score of 910 places it in the 23rd percentile of all CPUs in the database, making it a modest performer by modern standards. With a 35 W TDP, it targets low-power builds, but its performance profile tells a more nuanced story across single-threaded and multi-threaded workloads.

Benchmark Performance

The i3-4330T’s average score of 910 sits in a tight cluster of comparable processors. Its nearest rival, the AMD PRO A12-9800E, matches it exactly with a score of 910 and a delta of 0%. The Intel Xeon W3540 trails by a hair at 909 (0.1% delta), while the Intel Core i5-5300U leads by the same margin at 911 (-0.1% delta). The Intel Core i5-4258U comes in at 906, putting the i3-4330T 0.4% ahead. These deltas are negligible—within a rounding error—meaning the i3-4330T is effectively tied with all four rivals in overall benchmark performance. The data shows no meaningful separation among these chips; the i3-4330T does not outclass or fall behind its immediate competition by any practical margin.

Delving into the Cinebench results reveals where the processor’s strengths and weaknesses lie. In Cinebench R15 multi-core, it scores 266 points. Moving to the more demanding R20 test, the multi-core score jumps to 1110, and the single-core score is 156. In R23, the multi-core result is 2644, while the single-core result is 373. These numbers, taken together, indicate that the i3-4330T scales reasonably well across its two physical cores and four threads—the multi-core scores are substantially higher than their single-core counterparts, as expected for a processor with Hyper-Threading. However, the absolute values are low; the 23rd percentile ranking underscores that this chip sits near the bottom of the performance distribution. It is not a competitor for modern high-end desktops, but it holds its own against other low-power and older parts.

Power and Thermals

The i3-4330T is rated at a 35 W TDP, placing it in the ultra-low-power class for desktop processors. This figure is a key differentiator from mainstream desktop chips, which often draw 65 W or more. The low TDP means the processor can be cooled by a modest air cooler, and it is well-suited for compact or silent PC builds where heat dissipation is a concern. The 22 nm manufacturing process, with 1.4 billion transistors on a 177 mm² die, contributes to this efficiency. The process node and die size are indicative of a mature, power-conscious design rather than a performance-oriented one. The absence of a boost clock further ensures that power draw remains consistent under load, avoiding the transient spikes seen in processors with aggressive turbo modes. For system builders, the 35 W rating implies that a basic stock cooler or a low-profile aftermarket unit will suffice; no exotic cooling is required. The processor’s memory support for DDR3 and dual-channel configuration also aligns with a low-power, value-oriented platform.

Single-Thread vs Multi-Thread Behavior

The i3-4330T’s single-thread performance is modest but not embarrassing. In Cinebench R20, it scores 156 in the single-core test, while in R23 it reaches 373. These scores are typical for a dual-core Haswell part at 3.00 GHz. The multi-core results—1110 in R20 and 2644 in R23—are roughly seven times the single-core figures, indicating that the processor’s two cores and four threads are being utilized effectively. The scaling is near-linear, which is a positive sign for multi-threaded workloads that can use four threads. However, the absolute single-thread performance is low by today’s standards, meaning that lightly threaded applications—such as older games or office software that rely on one or two cores—will not see the same responsiveness as with a higher-clocked or more modern chip. The gap between single- and multi-core scores also suggests that the i3-4330T is better suited to batch tasks like video encoding or rendering that can use all threads, rather than latency-sensitive interactive workloads. For a 35 W part, the multi-threaded efficiency is respectable, but users should not expect flagship-level single-thread speed.

Who Should Consider It

The i3-4330T is not a processor for demanding gaming or heavy content creation. Its 23rd percentile ranking and low absolute scores in Cinebench—266 in R15 multi-core, 1110 in R20 multi-core, and 2644 in R23 multi-core—place it far below contemporary mainstream CPUs. However, for users whose workloads are light and multi-threaded, it can be a serviceable option. Office productivity, web browsing, and document editing do not require high single-thread performance, and the processor’s four threads can handle parallel tasks like spreadsheet calculations or batch file conversion without strain. The integrated HD 4600 graphics eliminate the need for a discrete GPU in basic systems, making it a candidate for home servers, media PCs, or low-cost builds where power consumption is a priority. The 35 W TDP and 22 nm process make it an efficient choice for always-on systems. On the other hand, gamers should look elsewhere; the low single-core scores (156 in R20, 373 in R23) will bottleneck many modern titles, and the integrated graphics are not designed for 3D workloads. Similarly, video editors or 3D artists will find the multi-core performance insufficient for rendering complex scenes. The i3-4330T is best suited for users who need a quiet, low-power desktop for basic tasks, and who prioritize energy efficiency over raw speed. Its benchmark performance is statistically indistinguishable from its closest rivals—the AMD PRO A12-9800E, Xeon W3540, i5-5300U, and i5-4258U—so any of these chips would deliver comparable real-world results. If the workload is limited to web, office, and light media, the i3-4330T is a competent, if unremarkable, choice.
