Architecture Differences

Both processors belong to the same Haswell architecture, manufactured on a 22 nm process node by Intel, with a die size of 177 mm² and 1,400 million transistors. They share the same core configuration: 2 physical cores with 4 threads, and neither has an unlocked multiplier. The socket is identical, Intel Socket 1150, and both support DDR3 memory in a dual-channel configuration.

The primary architectural distinction lies in the clock frequency. The Intel Core i3-4350T runs at a base clock of 3.10 GHz, while the Intel Core i3-4330T is set to 3.00 GHz. This 0.10 GHz difference is the sole factor separating the two in terms of compute capability, as there are no differences in cache hierarchy, process node, or core count.

Memory bandwidth is a point of divergence in the recorded specifications. The Intel Core i3-4350T lists a memory bandwidth of 25.6 GB/s, whereas the Intel Core i3-4330T does not have a recorded memory bandwidth figure. PCIe support also differs slightly in documentation: the i3-4350T specifies "Gen 3, 16 Lanes (CPU only)", while the i3-4330T simply lists "Gen 3". Both processors do not support ECC memory.

The production status and part numbers differ as well. The Intel Core i3-4350T is marked as end-of-life, with a part number of SR1JUSR1PA. The Intel Core i3-4330T does not have a production status recorded, and its part number is SR1NK. The launch MSRP is listed only for the i3-4350T at $138, while the i3-4330T has no launch MSRP recorded in the database.

Head-to-Head Benchmarks

The benchmark results consistently favor the Intel Core i3-4350T across all five recorded tests. The largest margin appears in Cinebench R15 multi-core, where the i3-4350T scores 271 against the i3-4330T's 265, a lead of 2.3%. This is the only test where the delta exceeds two percent, indicating that the clock speed advantage translates into a slightly wider gap in older rendering workloads.

In Cinebench R20 multi-core, the i3-4350T scores 1130 versus 1108 for the i3-4330T, a 2% advantage. The single-core variant of R20 shows a tighter race: 159 to 156, a 1.9% lead for the i3-4350T. The Cinebench R23 multi-core test produces a score of 2692 for the i3-4350T and 2639 for the i3-4330T, also a 2% difference. The closest result is in Cinebench R23 single-core, where the i3-4350T scores 380 and the i3-4330T scores 372, a 2.2% edge.

The data shows a clear pattern: the i3-4350T wins all five head-to-head comparisons, with deltas ranging from 1.9% to 2.3%. The average benchmark score reflects this, with the i3-4350T at 926 and the i3-4330T at 908. The percentile rankings align, placing the i3-4350T at the 25th percentile and the i3-4330T at the 24th.

When placed against their nearest rivals, the scores are closely clustered. The i3-4350T's average of 926 is nearly identical to the Intel Core i5-4288U, which scores 927, a delta of -0.1%. It is also 0.2% ahead of the Intel Celeron G6900TE (925) and 0.5% ahead of the AMD FX-4320 (921). The i3-4330T's average of 908 matches both the Intel Core i3-10110Y and the AMD Ryzen 3 3250U exactly, with a 0% delta, while it trails the AMD PRO A12-9800E by 0.3% and leads the AMD A10-7860K by 0.4%.

The Verdict

The benchmark data is unambiguous in favor of the Intel Core i3-4350T. It wins every recorded test, from Cinebench R15 multi-core to Cinebench R23 single-core, with margins between 1.9% and 2.3%. The higher base clock of 3.10 GHz provides a measurable, consistent advantage over the 3.00 GHz of the i3-4330T across all workloads, both multi-threaded and single-threaded. For users prioritizing maximum compute performance from this pair, the i3-4350T is the logical choice.

The i3-4330T is not without merit. Its average benchmark score of 908 places it alongside modern low-power parts like the Intel Core i3-10110Y and the AMD Ryzen 3 3250U, both of which match it exactly. The 24th percentile ranking shows it remains competitive in the entry-level desktop space. However, within the context of these two specific processors, the i3-4330T offers no advantage in any measured dimension. It has the same core count, same cache, same integrated graphics, and same TDP of 35 watts. The only recorded differences are the lower clock speed and the earlier release date.

The choice between the two depends on availability and timing. The i3-4350T is marked as end-of-life, while the i3-4330T has no production status recorded, suggesting it may still be in the supply chain. The i3-4350T also has a recorded launch MSRP of $138, but since the i3-4330T has no such figure, direct price comparison is not possible from the data. Based purely on performance, the i3-4350T is the superior part, with a 2% or better lead in every benchmark test. For users who already own an i3-4330T, the performance uplift from upgrading to the i3-4350T would be modest, around 2% in multi-threaded workloads. For new builds, the i3-4350T is the stronger performer, but both CPUs are near the bottom of the overall CPU performance distribution, sitting at the 25th and 24th percentiles respectively.
