Intel Core i3-12300HE vs Intel Core i7-1375PRE Comparison

The Verdict

The data presents an unusual outcome: the Intel Core i3-12300HE wins all six head-to-head benchmark comparisons against the Intel Core i7-1375PRE, despite the i7 having more cores, threads, cache, and a higher boost clock. The benchmark results show the i3-12300HE leading by a consistent 0.2% in every multi-core test (Cinebench R15, R20, and R23) and in two of the three single-core tests, with the R15 single-core test ending in an exact tie at 245 points. The average benchmark scores tell the same story: the i3-12300HE averages 4995 across all tests, while the i7-1375PRE averages 4985, a difference of 10 points. Both processors sit at the 59th percentile among all CPUs, placing them in the same performance tier. The i3-12300HE is the pick for anyone prioritizing raw benchmark scores, even if the margin is razor-thin. The i7-1375PRE, however, offers a substantial core-count advantage (14 vs 8 cores) and double the L3 cache (24 MB vs 12 MB), which matters for workloads that scale beyond what Cinebench captures. For pure Cinebench performance, the i3-12300HE wins outright; for headroom in multi-threaded productivity, the i7-1375PRE is the more logical choice based on its physical resources, even though those resources do not translate into benchmark wins here.

Architecture Differences

The two processors come from different Intel generations. The i3-12300HE is based on Alder Lake architecture (codename Alder Lake-H) from the Core 12th Gen series, while the i7-1375PRE is built on Raptor Lake architecture (codename Raptor Lake-P). Both use the same 10 nm process node from Intel and share the same 217 mm² die size. The socket is identical — Intel BGA 1744 — which means both are mobile processors designed for the same physical platform.

The core configurations diverge significantly. The i3-12300HE has 8 cores and 12 threads, while the i7-1375PRE offers 14 cores and 20 threads. The L1 cache is identical at 80 KB per core, but the L2 cache differs: the i3 has 1.25 MB per core, while the i7 has 2 MB per core. The L3 cache also differs sharply — the i3 has 12 MB shared, while the i7 has 24 MB shared, exactly double. The integrated graphics also differ: the i3 uses UHD Graphics, while the i7 is equipped with Iris Xe Graphics 96EU. Both support DDR4 and DDR5 memory in dual-channel mode, both lack ECC memory support, and both provide PCIe Gen 4 with 20 lanes from the CPU.

The boost clock favors the i7-1375PRE at 4.80 GHz versus 4.30 GHz for the i3-12300HE. The base clock is identical at 1900 MHz for both. The TDP figures also differ: the i3-12300HE is rated at 45 W, while the i7-1375PRE is rated at 28 W, making the i7 more power-efficient on paper. The i7-1375PRE has a release date of January 3, 2023, while the i3-12300HE has no release date listed. Neither processor has an unlocked multiplier, and neither has a listed launch MSRP.

Head-to-Head Benchmarks

The benchmark results are remarkably consistent across all six Cinebench tests. In Cinebench R15 multi-core, the i3-12300HE scores 1740 against the i7-1375PRE's 1737, a 0.2% advantage. The R15 single-core test is a dead heat: both score exactly 245, with a deltaPct of 0. The i3-12300HE is declared the winner of that test by tie-breaking convention, but the scores are identical.

In Cinebench R20, the i3-12300HE scores 7254 multi-core versus 7239 for the i7-1375PRE, again a 0.2% edge. The single-core R20 result is 1023 for the i3 versus 1021 for the i7, a 0.2% gap. Cinebench R23 shows the same pattern: multi-core is 17272 for the i3 versus 17236 for the i7 (0.2% difference), and single-core is 2438 versus 2433 (0.2% difference).

The i3-12300HE wins all six head-to-head tests, with five of those wins by 0.2% and one by 0%. The largest absolute margin in any test is 36 points in Cinebench R23 multi-core (17272 vs 17236), which is within the noise of typical benchmark variation. The pattern suggests that the i3-12300HE has a slight efficiency advantage in Cinebench workloads, despite the i7's larger core count and higher boost clock. The i7-1375PRE's extra 6 cores and 8 threads do not translate into higher Cinebench scores, which may indicate thermal or power constraints at the 28 W TDP limit, or that the Raptor Lake-P architecture in this particular SKU is tuned conservatively.

Specification Differences

The two processors differ in several key specification fields. The core count differs: 8 cores for the i3-12300HE versus 14 cores for the i7-1375PRE. Thread count follows: 12 versus 20. The boost clock is higher on the i7-1375PRE at 4.80 GHz versus 4.30 GHz. The TDP is lower on the i7-1375PRE at 28 W versus 45 W. The architecture and codename differ — Alder Lake/Alder Lake-H versus Raptor Lake/Raptor Lake-P. The generation string also differs: "Core i3 (Alder Lake-H)" versus "Core i7 (Raptor Lake-P)". The L2 cache per core is 1.25 MB on the i3 versus 2 MB on the i7. The L3 cache is 12 MB shared on the i3 versus 24 MB shared on the i7. The integrated graphics differ: UHD Graphics versus Iris Xe Graphics 96EU. The part numbers are different: SRLE8 for the i3-12300HE and SRMRK for the i7-1375PRE. The i7-1375PRE has a release date of January 3, 2023, while the i3-12300HE has no release date listed. The series field is populated for the i3 ("Core 12th Gen") but null for the i7. Identical specifications include base clock (1900 MHz), socket (Intel BGA 1744), process node (10 nm), foundry (Intel), die size (217 mm²), L1 cache (80 KB per core), memory support (DDR4, DDR5), memory bus (Dual-channel), ECC memory (false), PCIe (Gen 4, 20 Lanes), market segment (Mobile), production status (Active), and multiplier unlock (false).

Where Each One Wins

The i3-12300HE wins in every measured benchmark category. In Cinebench R15 multi-core, it scores 1740 versus 1737. In R15 single-core, it ties at 245. In R20 multi-core, it scores 7254 versus 7239. In R20 single-core, it scores 1023 versus 1021. In R23 multi-core, it scores 17272 versus 17236. In R23 single-core, it scores 2438 versus 2433. If the selection criteria are strictly based on Cinebench performance, the i3-12300HE is the definitive choice. The 0.2% margins are consistent across all tests, indicating a systematic advantage rather than a one-off anomaly. The i3 also benefits from a higher TDP (45 W versus 28 W), which likely allows it to sustain boost clocks longer under sustained multi-core loads.

The i7-1375PRE's wins are not in benchmark scores but in hardware specifications. It offers 14 cores versus 8, 20 threads versus 12, a 4.80 GHz boost clock versus 4.30 GHz, 24 MB L3 cache versus 12 MB, and a more capable integrated GPU (Iris Xe Graphics 96EU versus UHD Graphics). For workloads that utilize many threads and are not covered by Cinebench — such as video encoding, 3D rendering with certain engines, or parallel compilation — the i7's additional cores and threads provide theoretical headroom. The i7 also has a lower TDP of 28 W, which makes it more suitable for thin-and-light laptops where thermal dissipation is limited. The i7-1375PRE is the pick for users who value the larger core count and cache for future-proofing, or who need the Iris Xe graphics for light gaming or GPU-accelerated tasks without a discrete GPU. The i3-12300HE is the pick for users who care about the specific Cinebench scores, which show it edging out the i7 across the board.
