Intel Core i3-7100T vs Intel Core i5-4670T Comparison

The Intel Core i5-4670T and Intel Core i3-7100T are two low-power desktop processors from different eras of Intel’s lineup. The data shows a clear split: the older i5-4670T wins the majority of benchmark comparisons thanks to its four physical cores, while the newer i3-7100T takes a single victory in a single-threaded test. The i5-4670T secures six wins out of seven head-to-head benchmarks, with the i3-7100T only managing to edge ahead in Geekbench single-core performance. These results position the i5-4670T as the stronger multi-threaded performer, while the i3-7100T shows its advantage in lightly-threaded workloads.

Where Each One Wins

The Intel Core i5-4670T dominates multi-core and multi-threaded workloads. Its four cores and four threads, combined with 6 MB of shared L3 cache, give it a decisive edge in any benchmark that scales across cores. In Cinebench R23 multi-core, the i5-4670T scores 3820 against the i3-7100T’s 3175, a 20.3% advantage. The same pattern appears in Cinebench R20 multi-core (1604 vs 1333, +20.3%) and Cinebench R15 multi-core (384 vs 319, +20.4%). The Geekbench multi-core test shows a narrower but still comfortable lead: 2563 vs 2230, a 14.9% difference.

The i3-7100T wins exactly one head-to-head test: Geekbench single-core. Its higher base clock of 3.40 GHz (the i5-4670T runs at 2.30 GHz base) and newer Kaby Lake architecture deliver a score of 1111, beating the i5-4670T’s 977 by 12.1%. This result reflects a common trade-off: newer architectures with higher clock speeds often excel in single-threaded tasks, even when they have fewer physical cores. However, the i5-4670T actually wins the Cinebench single-core tests. In Cinebench R23 single-core, it scores 539 vs 448 (+20.3%), and in Cinebench R20 single-core, it scores 226 vs 188 (+20.2%). This inconsistency suggests that the i3-7100T’s Geekbench win may not translate to all single-threaded applications.

For users running heavily threaded applications—video rendering, 3D modeling, compilation—the i5-4670T is clearly the better choice. Its four physical cores provide a substantial advantage over the i3-7100T’s two cores, even though the i3-7100T has four threads via Hyper-Threading. The i5-4670T also carries a 35th percentile ranking among all CPUs, one point higher than the i3-7100T’s 34th percentile. The average benchmark score for the i5-4670T is 1271, slightly ahead of the i3-7100T’s 1258.

Architecture Differences

The two processors represent distinct architectural generations. The Intel Core i5-4670T is built on the Haswell architecture using a 22 nm process node, manufactured by Intel with 1,400 million transistors on a 177 mm² die. The i3-7100T uses the Kaby Lake architecture on a 14 nm process node, a newer and denser manufacturing process. The newer process node allows the i3-7100T to achieve a higher base clock (3.40 GHz) while consuming less power (35 W TDP) compared to the i5-4670T’s 45 W TDP.

Core and cache configurations differ significantly. The i5-4670T has four physical cores and four threads, while the i3-7100T has two physical cores and four threads. Both processors share 64 KB of L1 cache and 256 KB of L2 cache per core, but the L3 cache differs: the i5-4670T has 6 MB shared, while the i3-7100T has 3 MB shared. This means the i5-4670T offers both more physical cores and twice the last-level cache, which contributes to its multi-threaded advantage.

Memory support is another major divergence. The i5-4670T supports DDR3 memory, while the i3-7100T supports DDR4 memory with a memory bandwidth of 38.4 GB/s. Both use dual-channel memory buses. The i3-7100T also lists a more detailed PCIe specification: Gen 3 with 16 lanes (CPU only), while the i5-4670T simply states Gen 3. Integrated graphics differ as well: the i5-4670T includes Intel HD 4600, while the i3-7100T features Intel HD 630. The i3-7100T uses the Intel Socket 1151, while the i5-4670T uses Intel Socket 1150, meaning they are not interchangeable in a motherboard.

The release dates show a generational gap: the i5-4670T launched on 2013-06-01, while the i3-7100T launched on 2017-01-02. The i3-7100T’s production status is listed as Active, while the i5-4670T has no production status listed. Neither processor has an unlocked multiplier, and both target the desktop market.

Head-to-Head Benchmarks

The most striking result in the head-to-head data is the consistency of the i5-4670T’s multi-core wins. Across three generations of Cinebench (R15, R20, and R23), the i5-4670T wins the multi-core tests by nearly identical margins. In Cinebench R15 multi-core, the i5-4670T scores 384 against 319 for the i3-7100T, a 20.4% delta. The R20 multi-core test shows a 20.3% delta (1604 vs 1333), and the R23 multi-core test shows a 20.3% delta (3820 vs 3175). This uniformity suggests that the performance gap is largely due to the i5-4670T’s two additional physical cores, which provide a consistent advantage regardless of the benchmark version.

The single-core results are more nuanced. In Cinebench R20 single-core, the i5-4670T wins with a 226 score against 188 for the i3-7100T, a 20.2% delta. In Cinebench R23 single-core, the i5-4670T wins again with 539 vs 448, a 20.3% delta. However, the Geekbench single-core test flips the result: the i3-7100T wins with 1111 vs 977, a 12.1% delta in its favor. This discrepancy between Cinebench and Geekbench single-core results is notable. The i3-7100T’s higher base clock (3.40 GHz vs 2.30 GHz) and newer Kaby Lake architecture may explain its Geekbench advantage, but the Cinebench results suggest that the i5-4670T’s older architecture can still outperform it in certain single-threaded workloads.

The Geekbench multi-core test shows a smaller gap than the Cinebench tests. The i5-4670T scores 2563, while the i3-7100T scores 2230, a 14.9% delta. This is still a clear win for the i5-4670T, but the margin is narrower than the 20%+ deltas seen in Cinebench. This could indicate that Geekbench’s multi-core workload does not scale as well with additional cores, or that the i3-7100T’s higher clock speed helps it close the gap.

Looking at the nearest rivals provides additional context. The i5-4670T’s average benchmark score of 1271 places it just above the Intel Core i3-1005G1 (1265, +0.5%) and just below the Intel Core i5-4430S (1274, -0.2%). The i3-7100T’s average score of 1258 puts it slightly below the AMD Athlon 200GE (1261, -0.2%) and the Intel Core i7-3615QM (1260, -0.2%). Both processors sit in a similar performance tier, with the i5-4670T holding a marginal average score advantage of 13 points. The percentile rankings reinforce this: the i5-4670T ranks in the 35th percentile, the i3-7100T in the 34th percentile. The data shows that the i5-4670T is the stronger processor overall, but the i3-7100T offers better single-thread performance in Geekbench and a lower TDP.
