Intel Core i3-1115GRE vs Intel Core i3-4370 Comparison

The Intel Core i3-4370 and Intel Core i3-1115GRE represent two distinct eras of Intel's dual-core design, separated by six years of architectural evolution. While both processors share the same core and thread count, the benchmark data reveals a consistent performance advantage for the newer Tiger Lake chip across every measured workload. The i3-1115GRE wins all five head-to-head comparisons, with the i3-4370 failing to secure a single victory in the tested disciplines.

Head-to-Head Benchmarks

The most striking pattern in the benchmark results is the uniformity of the performance gap. In the Cinebench R15 multicore test, the i3-1115GRE scores 392 against the i3-4370's 330, a delta of -15.8% from the perspective of the older chip. This margin repeats almost identically in the R20 multicore test, where the newer processor posts 1637 versus 1379 for the Haswell part. The R23 multicore test shows the same story: 3899 for the i3-1115GRE against 3284 for the i3-4370, again with a -15.8% delta.

Single-core performance tells a similar tale, though with slightly different margins. The Cinebench R20 single-core test shows the i3-1115GRE at 231 and the i3-4370 at 194, a -16% delta. The R23 single-core test follows with 550 versus 463, maintaining the -15.8% gap seen in the multicore tests. Across all five benchmarks, the i3-1115GRE leads by roughly 16%, a consistent and meaningful margin that reflects the architectural improvements rather than any single workload advantage.

Notably, the Cinebench R15 single-core test appears only in the i3-1115GRE's benchmark list with a score of 55, while the i3-4370 lacks a corresponding entry. This asymmetry in available data means the head-to-head comparison relies on the R20 and R23 single-core tests, which both show the newer chip ahead. The average benchmark scores for the two processors are nearly identical — 1130 for the i3-4370 and 1127 for the i3-1115GRE — placing them in the same 32nd percentile among all CPUs, but the individual test results clearly favor the Tiger Lake part.

Where Each One Wins

The i3-1115GRE wins every benchmark category in which both processors were tested. This includes all multicore and single-core Cinebench iterations, making it the unequivocal choice for compute-heavy workloads such as rendering, video encoding, or any task that scales with raw CPU throughput. Its multicore scores of 392 (R15), 1637 (R20), and 3899 (R23) demonstrate a substantial advantage in threaded applications, while its single-core results of 231 (R20) and 550 (R23) indicate superiority in lightly threaded tasks like web browsing or office productivity.

The i3-4370, with zero wins in the head-to-head comparison, does not outperform the i3-1115GRE in any tested metric. However, its position is not without merit in the broader context. Its average benchmark score of 1130 places it in a statistical dead heat with rivals like the Intel Pentium Gold G5500 (1130, 0% delta) and the Intel Core i5-4690T (1129, 0.1% delta). The i3-1115GRE's average score of 1127 similarly ties it with the Intel Core i5-3330S (1128, -0.1% delta) and the Intel Core i7-2720QM (1128, -0.1% delta). These rival comparisons suggest that while the two processors are separated by performance, both occupy a similar tier in the overall CPU landscape.

For users prioritizing single-threaded responsiveness, the i3-1115GRE's 550 R23 single-core score represents a clear step up from the i3-4370's 463. For those focused purely on multi-threaded throughput, the newer chip's 3899 R23 result versus 3284 shows the same advantage. In essence, the i3-1115GRE wins across the board, with the i3-4370 offering no benchmark-documented use case where it takes the lead.

Architecture Differences

The two processors are built on fundamentally different foundations. The i3-4370 uses the Haswell architecture on a 22 nm process node, with a die size of 177 mm² and 1,400 million transistors. The i3-1115GRE employs the Tiger Lake architecture (Willow Cove-U) on a 10 nm process, with a smaller die size of 144 mm². This process shrink explains part of the performance-per-watt advantage, though the transistor count for the Tiger Lake part is not listed in the data.

Caching structures differ markedly between the two. The i3-4370 offers 64 KB of L1 cache per core, 256 KB of L2 per core, and 4 MB of shared L3 cache. The i3-1115GRE increases each level: 80 KB of L1 per core, 1.25 MB of L2 per core, and 6 MB of shared L3. This larger cache hierarchy, particularly the 50% increase in L3 capacity, likely contributes to the newer chip's higher scores in cache-sensitive workloads.

Clock speeds also diverge. The i3-4370 has a fixed base clock of 3.80 GHz with no boost capability, while the i3-1115GRE starts at 2.20 GHz but can boost to 3.90 GHz. Despite the lower base clock, the Tiger Lake part's ability to dynamically raise its frequency allows it to outperform the older chip in both single- and multi-threaded tests. The i3-4370's TDP of 54 watts is more than triple the i3-1115GRE's 15 watts, underscoring the efficiency gains of the newer architecture.

Memory support and platform features further distinguish the pair. The i3-4370 supports DDR3 memory in a dual-channel configuration, while the i3-1115GRE supports DDR4 and LPDDR4X, also dual-channel. The newer chip adds ECC memory support, a feature absent from the older part. PCIe generations differ as well: the i3-4370 uses Gen 3, while the i3-1115GRE provides Gen 4 with 4 lanes (CPU only). The integrated graphics also change, from Intel HD 4600 on the Haswell chip to UHD Graphics G4 48EU on the Tiger Lake part.

The i3-4370 is a desktop processor on Intel Socket 1150, released in 2014, while the i3-1115GRE is a mobile part on Intel BGA 1449, released in 2020 with an active production status. The i3-1115GRE carries a launch MSRP of $338, a detail noted once here. Neither processor has an unlocked multiplier, and the i3-1115GRE has a listed part number of SRK13.

The Verdict

The benchmark data is unambiguous: the Intel Core i3-1115GRE is the faster processor in every tested category. Its wins across all five Cinebench tests, with deltas ranging from -15.8% to -16%, demonstrate a consistent and significant performance lead over the i3-4370. For any workload measured by these benchmarks — whether single-threaded or multi-threaded — the Tiger Lake chip is the superior choice.

The i3-4370's only consolation is its competitive standing among its own peers. Its average score of 1130 ties it with the Pentium Gold G5500 and puts it within 0.1% of the Core i5-4690T, indicating it remains a functional dual-core option for its era. However, against the i3-1115GRE, it has no documented advantages in the head-to-head results.

Buyers should choose the i3-1115GRE if they need the higher multicore throughput (3899 vs 3284 in R23), better single-core performance (550 vs 463 in R23), and the efficiency of a 15-watt TDP. The i3-4370 might still serve adequately in legacy desktop systems, but the data provides no reason to prefer it over the newer part in raw performance terms. The i3-1115GRE also brings ECC memory support and Gen 4 PCIe, features that the i3-4370 lacks entirely.
