Intel Core i3-12300HE vs Intel Core i5-12600HE Comparison

The Intel Core i3-12300HE and Intel Core i5-12600HE are both members of Intel’s 12th Gen Alder Lake-H mobile lineup, sharing the same 10 nm process node and 45 W TDP. Despite the i5’s higher core and thread counts, the benchmark data reveals an unusually tight competition. The i3-12300HE actually wins every single head-to-head benchmark in the Cinebench suite, though by margins so slim they are nearly indistinguishable in real-world use. Both processors land at the 59th percentile among all CPUs, with average benchmark scores of 4995 for the i3 and 4980 for the i5. The i3’s lead is consistent but minuscule, ranging from 0.3% to 0.4% across all tests, which suggests that the two chips are effectively performance equals in the workloads tested.

Head-to-Head Benchmarks

The most striking finding in the data is that the Intel Core i3-12300HE outperforms the Intel Core i5-12600HE in every single benchmark recorded, despite the i5 having 12 cores and 16 threads compared to the i3’s 8 cores and 12 threads. In Cinebench R23 multi-core, the i3 scores 17272 against the i5’s 17217, a delta of 0.3%. The single-core result for R23 is similarly close: 2438 for the i3 versus 2430 for the i5, again a 0.3% advantage. This pattern holds across the older Cinebench versions as well. In R20 multi-core, the i3 posts 7254 while the i5 manages 7231, and in R20 single-core, the i3 scores 1023 against 1020. The margins in R15 are even tighter: 1740 versus 1735 in multi-core and 245 versus 244 in single-core.

The i3’s largest win comes in Cinebench R15 single-core, where it leads by 0.4%. Every other test sees a 0.3% delta in favor of the i3. What makes this remarkable is the specification sheet: the i5-12600HE has 50% more cores and 33% more threads, yet it cannot convert that hardware advantage into a benchmark victory. The i5’s base clock of 2.50 GHz and boost clock of 4.50 GHz are both higher than the i3’s 1.90 GHz base and 4.30 GHz boost, yet the i3 still edges ahead. This suggests that the i5’s additional cores may be constrained by the same 45 W TDP, preventing them from running at full sustained clocks under load. The i3’s lower core count likely allows it to maintain higher clocks on its active cores, which is sufficient to offset the i5’s raw core advantage in these Cinebench workloads.

Looking at the broader competitive landscape, both CPUs sit in the same performance tier. The i3-12300HE’s nearest rival, the Intel Xeon W-2150B, has an average score of 4992, putting it 0.1% behind the i3. The AMD Ryzen 5 PRO 5650G and Intel Core i5-13500TE both score 5002, which is 0.1% ahead of the i3. The i5-12600HE, meanwhile, is 0.1% behind the Intel Core i7-1375PRE and 0.2% behind the Xeon W-2150B. The i5’s closest competitor, the AMD Ryzen Embedded V3C48, scores 4967, which is 0.3% behind. In essence, the two processors are bracketed by the same group of rivals, and their own head-to-head delta of 0.3% is smaller than the gap between either chip and several of its nearest competitors.

Architecture Differences

Both processors are built on Intel’s Alder Lake architecture, specifically the Alder Lake-H mobile variant, and are fabricated on Intel’s 10 nm process node. The die size is identical at 217 mm², and both use the Intel BGA 1744 socket. The core layouts differ significantly, though: the i3-12300HE has 8 cores and 12 threads, while the i5-12600HE has 12 cores and 16 threads. This core count difference is the primary architectural distinction, as the i5 is designed to offer more parallel processing capacity. However, the benchmark results show that this extra capacity does not translate into higher Cinebench scores, likely due to power and thermal constraints within the 45 W TDP envelope.

Cache hierarchies also differ. Both chips have 80 KB of L1 cache per core and 1.25 MB of L2 per core, but the shared L3 cache is larger on the i5: 18 MB versus 12 MB on the i3. This additional L3 cache on the i5 could theoretically improve performance in cache-sensitive workloads, but the Cinebench data does not reflect any such benefit. The integrated graphics differ as well: the i3 ships with UHD Graphics, while the i5 features Iris Xe 80EU. Both processors support DDR4 and DDR5 memory, are dual-channel, and offer Gen 4 PCIe with 20 lanes from the CPU. Neither supports ECC memory, and both have locked multipliers.

The fact that the i5’s architectural advantages—more cores, more threads, more L3 cache, and higher clocks—do not yield higher benchmark scores suggests that the Alder Lake-H design, when constrained to 45 W, reaches a performance plateau. The i3’s lower core count may allow it to boost higher and sustain those boosts for longer, since there are fewer active cores competing for the same power budget. This is a classic example of diminishing returns in a thermally limited mobile form factor, where the i5’s additional hardware becomes underutilized.

Specification Differences

The two processors share many specifications: both are Alder Lake-H mobile chips on the 10 nm node, use the Intel BGA 1744 socket, have a 45 W TDP, support DDR4/DDR5 memory, and offer dual-channel memory with Gen 4 PCIe (20 lanes). The differences appear in the core configuration, clock speeds, cache, and integrated graphics. The i5-12600HE has 12 cores and 16 threads, compared to the i3-12300HE’s 8 cores and 12 threads. The i5’s base clock is 2.50 GHz and boost clock is 4.50 GHz, while the i3 runs at 1.90 GHz base and 4.30 GHz boost. The i5 has 18 MB of shared L3 cache, while the i3 has 12 MB. The i5’s integrated graphics are Iris Xe 80EU, whereas the i3 uses UHD Graphics. The part numbers differ as well: SRLE5 for the i5 and SRLE8 for the i3. Both are listed as Active in production, have no launch MSRP, and are not multiplier-unlocked.

The Verdict

Based strictly on the benchmark data, the Intel Core i3-12300HE is the superior processor for Cinebench workloads. It wins all six head-to-head tests, with the largest margin being 0.4% in R15 single-core and the rest at 0.3%. Its average benchmark score of 4995 is higher than the i5’s 4980, and it even outperforms the i5 against shared rivals like the Intel Xeon W-2150B, where the i3 leads by 0.1% while the i5 trails by 0.2%. The i5’s only advantages are on paper: more cores, more threads, higher clocks, and more L3 cache, none of which appear in the performance results.

For users choosing between these two, the i3-12300HE is the pick for anyone prioritizing raw Cinebench scores. The i5-12600HE’s extra cores and threads do not help in these benchmarks, and its higher boost clock of 4.50 GHz is not enough to overcome the i3’s apparently more efficient use of the 45 W power envelope. The i5 does offer better integrated graphics with Iris Xe 80EU, which could matter for systems without a discrete GPU, but the data does not quantify that advantage. The i5 also has a larger L3 cache, which might benefit other workloads not represented in the Cinebench suite, but the available evidence shows the i3 winning every test. In short, the i3-12300HE is the better performer in this comparison, while the i5-12600HE is a higher-specified chip that fails to convert its hardware into benchmark victories.
