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

Head-to-Head Benchmarks

The benchmark data between the Intel Core i5-4670R and the Intel Core i3-7100T shows a decisive, consistent victory for the older Haswell part. Across all five shared Cinebench tests, the i5-4670R wins outright, with the i3-7100T failing to claim a single head-to-head victory. The margin is remarkably uniform, hovering near the 40% mark in every workload.

In Cinebench R15 multi-core, the i5-4670R scores 448 against the i3-7100T's 319, a 40.4% advantage. That gap persists in Cinebench R20 multi-core, where the i5-4670R posts 1868 versus 1333, a 40.1% lead. The same story repeats in Cinebench R23 multi-core: 4448 for the i5-4670R, 3175 for the i3-7100T, again a 40.1% delta. The consistency of these multi-core margins suggests the i5-4670R's four physical cores provide a structural advantage that the i3-7100T's two cores with Hyper-Threading cannot overcome, even when the newer chip runs at a higher base clock.

Single-core results are equally lopsided. In Cinebench R20 single-core, the i5-4670R scores 263 versus the i3-7100T's 188, a 39.9% lead. Cinebench R23 single-core shows 627 for the i5-4670R against 448 for the i3-7100T, a 40% difference. This is notable because single-core performance typically favors newer architectures with higher IPC. The i3-7100T's Kaby Lake architecture and 3.40 GHz base clock do not translate into a single-core win; the i5-4670R's 3.70 GHz boost clock and Haswell design remain comfortably ahead.

The average benchmark scores reinforce the pattern. The i5-4670R averages 1286 across its benchmark suite, while the i3-7100T averages 1258. The i5-4670R sits at the 35th percentile among all CPUs, and the i3-7100T at the 34th, so both are mid-range parts historically, but the i5-4670R holds a slight overall edge. Its nearest rivals include the Intel Core i5-3570 at an identical 1286 average score, and the AMD Opteron 6272 at 1288. The i3-7100T's nearest rivals include the Intel Core i7-3615QM at 1260 and the AMD Athlon 200GE at 1261, all within 0.6% of its score. The data shows the i3-7100T sits in a tightly packed cluster of similar performers, while the i5-4670R edges into slightly higher territory.

FAQ

Q: Which CPU wins more benchmark comparisons?

A: The Intel Core i5-4670R wins all five head-to-head benchmark comparisons listed in the database. The Intel Core i3-7100T wins none. The i5-4670R's margins range from 39.9% to 40.4% across the tested Cinebench workloads.

Q: How does the multi-core performance compare?

A: In Cinebench R23 multi-core, the i5-4670R scores 4448, which is 40.1% ahead of the i3-7100T's 3175. Similar margins appear in Cinebench R20 multi-core (1868 versus 1333, a 40.1% gap) and Cinebench R15 multi-core (448 versus 319, a 40.4% gap).

Q: Is the newer i3-7100T faster in single-core tests?

A: No. Despite the i3-7100T's newer Kaby Lake architecture and a higher base clock of 3.40 GHz, the i5-4670R leads in every single-core test. In Cinebench R23 single-core, the i5-4670R scores 627 versus 448, a 40% advantage. In Cinebench R20 single-core, the scores are 263 versus 188, a 39.9% lead.

Q: What are the average benchmark scores for each CPU?

A: The i5-4670R has an average benchmark score of 1286, placing it at the 35th percentile of all CPUs. The i3-7100T has an average score of 1258, placing it at the 34th percentile. The i5-4670R's score matches its nearest rival, the Intel Core i5-3570, exactly.

Q: Which CPU has a higher TDP?

A: The i5-4670R has a TDP of 65 watts, while the i3-7100T has a TDP of 35 watts. The i3-7100T draws less power, which may be relevant for thermal-constrained systems, but the benchmark data shows it also delivers less performance.

Q: Does the i3-7100T appear in any benchmark test that the i5-4670R does not?

A: Yes. The database includes Geekbench results for the i3-7100T: 2230 in multi-core and 1111 in single-core. No Geekbench scores are listed for the i5-4670R, so a direct comparison on that test is not possible from the recorded data.

The Verdict

The data points to one clear conclusion: the Intel Core i5-4670R is the faster processor in every measurable shared benchmark. Its 40% lead across all Cinebench tests, both single-core and multi-core, is too large to ignore. Users prioritizing raw compute performance should select the i5-4670R without hesitation.

The i3-7100T's only advantages are efficiency and platform modernity. Its 35-watt TDP is nearly half the i5-4670R's 65 watts, which could matter in small-form-factor or low-noise builds. It also supports DDR4 memory and has a newer integrated graphics solution, the Intel HD 630, compared to the i5-4670R's Iris Pro 5200. However, the benchmark data shows no performance benefit from these newer features. The i3-7100T's average score of 1258 is actually lower than the i5-4670R's 1286.

For anyone whose primary concern is application performance, the i5-4670R is the clear pick. The i3-7100T makes sense only when power draw and newer memory support take priority over compute throughput. The recorded data does not support choosing the i3-7100T for speed.

Specification Differences

The two processors differ in nearly every core specification. The i5-4670R has 4 cores and 4 threads, while the i3-7100T has 2 cores and 4 threads. Base clocks differ: the i5-4670R runs at 3.00 GHz, the i3-7100T at 3.40 GHz. The i5-4670R offers a boost clock of 3.70 GHz, while the i3-7100T has no boost capability listed.

Cache configurations differ as well. Both have 64 KB of L1 and 256 KB of L2 per core, but the shared L3 cache is 4 MB on the i5-4670R versus 3 MB on the i3-7100T. The i5-4670R supports DDR3 memory; the i3-7100T supports DDR4 with dual-channel memory and a listed bandwidth of 38.4 GB/s. The i5-4670R lists no memory bus or bandwidth figures.

The i5-4670R uses an Intel BGA 1364 socket, while the i3-7100T uses Intel Socket 1151. The i5-4670R has an unlocked multiplier; the i3-7100T is locked. The i3-7100T lists a PCIe configuration of Gen 3 with 16 lanes (CPU only); the i5-4670R has no PCIe data recorded. Integrated graphics differ: the i5-4670R has Iris Pro 5200, the i3-7100T has Intel HD 630. The i3-7100T also has a part number, SR35P, while the i5-4670R does not list one.

Architecture Differences

The architecture gap is substantial. The i5-4670R uses the Haswell architecture on a 22 nm process node with 1,400 million transistors and a die size of 177 mm². The i3-7100T uses Kaby Lake on a 14 nm process node, with no transistor count or die size recorded. The i5-4670R belongs to the Core i5 (Haswell) generation; the i3-7100T belongs to the Core i3 (Kaby Lake) generation.

The i5-4670R was released in June 2013, while the i3-7100T came in January 2017. Both are listed as Active in production status, and both are manufactured by Intel. Neither supports ECC memory.

The core count difference is the most significant architectural divergence. Four physical cores on the i5-4670R versus two physical cores with four threads on the i3-7100T explains the consistent 40% performance gap. The i3-7100T's newer process node (14 nm versus 22 nm) and newer architecture (Kaby Lake versus Haswell) do not compensate for the missing physical cores in the benchmark data. The i5-4670R also has a larger shared L3 cache (4 MB versus 3 MB), which likely contributes to its multi-core and single-core advantages.

The i3-7100T's memory support is newer (DDR4 versus DDR3), and its listed memory bandwidth of 38.4 GB/s is an explicit figure the i5-4670R lacks. The i3-7100T's PCIe support is also documented as Gen 3 with 16 lanes, while the i5-4670R has no PCIe data in the database. However, these platform advantages do not show up in the Cinebench results, where the older Haswell part dominates. The data indicates that for compute-bound workloads, the i5-4670R's additional cores and larger cache outweigh the i3-7100T's architectural modernity and efficiency gains.
