Intel Core i7-12700E vs Intel Core i7-12800HE Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core i7-12700E wins every single head-to-head comparison against the Intel Core i7-12800HE. Out of six recorded Cinebench tests, the desktop part takes all six, with a consistent performance margin of roughly 6.4% across the board. This is not a case of one chip winning in some workloads and losing in others; the i7-12700E simply outperforms the mobile i7-12800HE in every measured metric.

Starting with multi-core performance, the i7-12700E scores 2406 in Cinebench R15 multi-core versus 2253 for the i7-12800HE, a delta of -6.4% from the perspective of the mobile chip. The pattern repeats in Cinebench R20 multi-core, where the i7-12700E posts 10029 against 9391, again a 6.4% gap. In Cinebench R23 multi-core, the desktop part reaches 23879 while the mobile chip manages 22360, another 6.4% difference. These results indicate that the i7-12700E consistently delivers more multi-threaded throughput, despite having fewer physical cores.

Single-core results tell the same story. The i7-12700E leads in Cinebench R15 single-core with 339 versus 318, a 6.2% advantage. In Cinebench R20 single-core, it scores 1415 against 1325, and in Cinebench R23 single-core, it posts 3371 versus 3156. The single-core margins are nearly identical to the multi-core margins, suggesting the advantage is not workload-specific but rather a general performance lead across the entire chip.

The average benchmark score reinforces this picture. The i7-12700E has an average benchmark score of 6776, placing it in the 62nd percentile of all CPUs. The i7-12800HE has an average score of 6467, also in the 62nd percentile, but roughly 4.8% lower in raw average score. The nearest rival data for each chip shows them competing in different neighborhoods: the i7-12800HE sits near the Intel Xeon D-2796TE (6510, -0.7%), the Intel Xeon W-2191B (6531, -1%), and the Intel Core i9-7960X (6533, -1%), while the i7-12700E sits near the AMD Ryzen Threadripper 2970WX (6760, 0.2%), the Intel Xeon Gold 6154 (6803, -0.4%), and the Intel Xeon D-2775TE (6711, 1%).

The data shows a clear hierarchy. The i7-12700E is the faster processor in every recorded benchmark, and the margin is consistent enough to be considered a structural advantage rather than a measurement artifact.

Architecture Differences

Both processors belong to Intel's Core 12th Gen series and share the Alder Lake architecture, but they are distinct variants targeting different market segments. The i7-12800HE is an Alder Lake-H mobile part with a 45 W TDP and an Intel BGA 1744 socket, while the i7-12700E is an Alder Lake-S desktop part with a 65 W TDP and an Intel Socket 1700. Both are built on Intel's 10 nm process node and fabricated by Intel, but they differ in die size: the mobile chip measures 217 mm², while the desktop chip measures 215 mm².

Core configuration is a notable difference. The i7-12800HE has 14 cores and 20 threads, while the i7-12700E has 12 cores and 20 threads. Both processors share the same L1 cache size of 80 KB per core and the same L2 cache size of 1.25 MB per core. The L3 cache differs slightly: the i7-12800HE has 24 MB shared, while the i7-12700E has 25 MB shared. This 1 MB difference in L3 is modest but consistent with the desktop part's higher performance in the recorded benchmarks.

Memory support is identical in terms of type and bus: both support DDR4 and DDR5 memory in a dual-channel configuration, and neither supports ECC memory. PCIe connectivity differs significantly. The i7-12800HE offers PCIe Gen 4 with 20 lanes (CPU only), while the i7-12700E offers PCIe Gen 5 with 20 lanes (CPU only). This gives the desktop part a newer PCIe generation, which is relevant for expansion card bandwidth.

Integrated graphics also differ. The i7-12800HE uses Iris Xe 96EU, while the i7-12700E uses UHD Graphics 770. Both are integrated solutions, but they represent different tiers of Intel's graphics lineup.

Neither processor has an unlocked multiplier, so both are locked for overclocking. The part numbers differ as well: SRLE6 for the i7-12800HE and SRL6D for the i7-12700E. The launch MSRP for the i7-12700E is $344; no launch MSRP is recorded for the i7-12800HE.

The Verdict

The benchmark data leads to a straightforward conclusion: the Intel Core i7-12700E is the faster processor in every recorded comparison. It wins all six Cinebench tests with a consistent margin of 6.4% in multi-core and between 6.2% and 6.4% in single-core. Its average benchmark score of 6776 is higher than the 6467 of the i7-12800HE, and both chips sit in the 62nd percentile of all CPUs.

The i7-12700E achieves this with fewer cores (12 vs 14) but a higher boost clock (4.80 GHz vs 4.60 GHz) and a larger L3 cache (25 MB vs 24 MB). The higher TDP of 65 W versus 45 W reflects its desktop design, which allows for sustained performance without the thermal constraints of a mobile platform.

For users choosing between these two, the i7-12700E is the clear pick on raw performance. It is a desktop processor with a higher average benchmark score, better single-core and multi-core results, and a newer PCIe generation. The i7-12800HE, as a mobile part with a lower TDP and BGA socket, is designed for laptops and compact systems where power efficiency and form factor matter more than peak performance.

The data does not show any benchmark where the i7-12800HE takes the lead. It records zero wins across the head-to-head comparisons, while the i7-12700E records six. The verdict is therefore not a matter of trade-offs; it is a matter of the desktop part being uniformly superior in the measured workloads.

Specification Differences

The two processors differ in several key specifications. The i7-12800HE has 14 cores, while the i7-12700E has 12 cores; both have 20 threads. The base clock of the i7-12800HE is 2.40 GHz versus 2.10 GHz for the i7-12700E, but the boost clock favors the desktop part at 4.80 GHz versus 4.60 GHz. TDP differs substantially: 45 W for the mobile chip and 65 W for the desktop chip.

The socket is different: Intel BGA 1744 for the i7-12800HE and Intel Socket 1700 for the i7-12700E. The codenames also differ: Alder Lake-H for the mobile part and Alder Lake-S for the desktop part. Die size is 217 mm² versus 215 mm². L3 cache is 24 MB shared for the i7-12800HE and 25 MB shared for the i7-12700E.

PCIe support differs by generation: the mobile chip uses PCIe Gen 4, while the desktop chip uses PCIe Gen 5, both with 20 lanes (CPU only). Integrated graphics differ: Iris Xe 96EU for the i7-12800HE and UHD Graphics 770 for the i7-12700E. The market segment is Mobile for the i7-12800HE and Desktop for the i7-12700E. Part numbers are SRLE6 and SRL6D respectively. The i7-12700E has a recorded launch MSRP of $344; the i7-12800HE has none listed.

Where Each One Wins

Based strictly on the recorded data, the Intel Core i7-12700E wins every benchmark category. In multi-core workloads, it outperforms the i7-12800HE in Cinebench R15 (2406 vs 2253), R20 (10029 vs 9391), and R23 (23879 vs 22360). In single-core workloads, it leads in Cinebench R15 (339 vs 318), R20 (1415 vs 1325), and R23 (3371 vs 3156). The desktop part also has a higher average benchmark score (6776 vs 6467) and a higher boost clock (4.80 GHz vs 4.60 GHz).

The i7-12800HE does not win any of the six head-to-head benchmark comparisons. Its advantages are structural rather than performance-based: it has more cores (14 vs 12), a lower TDP (45 W vs 65 W), and a BGA socket suitable for mobile integration. These characteristics make it suitable for systems where power draw and physical footprint are priorities, but the benchmark data shows it trails the i7-12700E in every measured workload.

The use-case split is therefore defined by platform rather than performance. The i7-12700E is the choice for desktop builds where the higher 65 W TDP and Socket 1700 are acceptable, and where the 6.4% multi-core advantage and 6.2% to 6.4% single-core advantage can be fully utilized. The i7-12800HE is the choice for mobile or compact systems that require a 45 W processor with a BGA 1744 socket, accepting lower benchmark scores in exchange for a form factor that the desktop part cannot serve. For anyone who can mount a Socket 1700 board, the i7-12700E is the better-performing option in every recorded test.
