Intel Core i5-10200H vs Intel Core i5-1145G7E Comparison

The Intel Core i5-1145G7E is the clear benchmark winner over the Intel Core i5-10200H, taking all six head-to-head comparisons with margins between 10.4% and 10.7%. This consistent advantage across both single-core and multi-core workloads indicates a fundamental architectural superiority rather than a workload-specific edge. The i5-1145G7E achieves this despite having a lower base clock of 1500 MHz compared to the i5-10200H's 2400 MHz, though both processors share an identical 4.10 GHz boost clock. Benchmark results show the Tiger Lake part outperforming its Comet Lake counterpart in every Cinebench iteration, with the largest single-core delta of 10.7% appearing in both Cinebench R20 and R23, while the smallest gap of 10.4% occurs in Cinebench R15 single-core.

Head-to-Head Benchmarks

The i5-1145G7E's dominance is absolute across all measured tests. In Cinebench R23 multi-core, the i5-1145G7E scores 7516 against the i5-10200H's 6795, a 10.6% advantage that reflects better sustained throughput under full load. The single-core R23 result tells a similar story: 1061 versus 959, again a 10.6% lead. These margins are remarkably consistent, suggesting the performance gap is structural and not dependent on thermal headroom or power delivery.

Cinebench R20 results reinforce the pattern. The multi-core test shows the i5-1145G7E at 3156 versus 2853, a 10.6% difference, while single-core hits 445 versus 402, a 10.7% gap. The R15 generation of tests produces nearly identical relative outcomes: multi-core 757 versus 684 (10.7% lead) and single-core 106 versus 96 (10.4% lead). With six wins out of six possible comparisons, the i5-1145G7E holds an unqualified performance advantage.

Interpreting these numbers in context, the i5-1145G7E's average benchmark score of 2174 places it at the 47th percentile of all CPUs, with its nearest rival being the AMD Ryzen 5 3400GE at 2175 (0% delta) and the Intel Core i7-1185GRE at 2178 (-0.2% delta). The i5-10200H averages 2154, also at the 47th percentile, with its closest competitor being the Intel Core i7-5950HQ at 2158 (-0.2% delta). Both processors sit in the same performance tier overall, but the head-to-head data shows the i5-1145G7E consistently outpaces its Comet Lake sibling by roughly a tenth of a percent more than a full 10% in every test category.

Architecture Differences

The two processors represent distinct Intel architectures and process nodes. The i5-1145G7E uses the Tiger Lake architecture built on Intel's 10 nm process, with a die size of 144 mm². Its codename is Tiger Lake-U, and it belongs to the Willow Cove-U generation. In contrast, the i5-10200H uses the Comet Lake architecture on a 14 nm process, with the codename Comet Lake-H and a generation designation of Comet Lake-H. The process node difference—10 nm versus 14 nm—explains much of the efficiency and performance gap, as the newer node allows for higher performance at lower power consumption.

Cache hierarchies differ substantially. The i5-1145G7E features 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 8 MB of shared L3 cache. The i5-10200H has 64 KB L1 per core, 256 KB L2 per core, and only 6 MB of shared L3. This means the Tiger Lake part offers 25% more L1, five times more L2 per core, and 33% more L3 overall—all of which contribute to its superior memory latency hiding and multi-core scaling.

Memory support also diverges. The i5-1145G7E supports DDR4 and LPDDR4X, while the i5-10200H supports DDR3 and DDR4. Both use dual-channel memory buses, but only the i5-10200H has a published memory bandwidth figure of 46.9 GB/s. The i5-1145G7E's PCIe implementation is Gen 4 with 4 lanes from the CPU, whereas the i5-10200H uses Gen 3. Integrated graphics differ as well: the i5-1145G7E carries Iris Xe Graphics G7 with 80 execution units, while the i5-10200H has the more basic UHD Graphics.

Other differences include socket type (BGA 1449 for the i5-1145G7E versus BGA 1440 for the i5-10200H), TDP (28W versus 45W), and release date (September 1, 2020 versus September 16, 2020). The i5-1145G7E has a launch MSRP of $312; the i5-10200H has no listed launch MSRP. Both are active production parts with 4 cores and 8 threads, unlocked multipliers set to false, and no ECC memory support.

The Verdict

The benchmark data is unambiguous: the Intel Core i5-1145G7E is the superior processor. It wins all six head-to-head comparisons with a minimum margin of 10.4% and a maximum of 10.7%. This consistent 10%+ advantage across single-core and multi-core workloads indicates that the Tiger Lake architecture's 10 nm process, larger caches, and newer memory support translate directly into measurable performance gains over the Comet Lake 14 nm design.

For users prioritizing raw performance, the i5-1145G7E is the clear choice. It delivers higher scores in every Cinebench test while operating at a lower TDP (28W versus 45W), making it more efficient as well as faster. The i5-10200H's higher base clock of 2400 MHz does not compensate for its architectural disadvantages, including smaller caches and older process node.

The i5-10200H is not without merit, however. It supports DDR3 memory in addition to DDR4, which may be relevant for legacy system compatibility. It also has a listed memory bandwidth of 46.9 GB/s, a specification the i5-1145G7E does not publish. But for anyone choosing between these two for a new build or upgrade, the data says the i5-1145G7E offers better performance in every measured category.

Where Each One Wins

The i5-1145G7E wins in all benchmark categories tested: Cinebench R15, R20, and R23, both single-core and multi-core. Its largest margins come in single-core R20 and multi-core R15, both at 10.7%. Its smallest margin is in single-core R15 at 10.4%. This makes it the recommended choice for workloads that benefit from strong per-core performance—such as lightly threaded applications—and for multi-threaded rendering or compilation tasks where its 10.6% multi-core advantage matters.

The i5-10200H has no benchmark wins in the head-to-head data. Its advantages are spec-based rather than performance-based: it has a higher base clock (2400 MHz versus 1500 MHz), a higher TDP (45W versus 28W), and support for DDR3 memory. It also has a listed memory bandwidth figure (46.9 GB/s) that the i5-1145G7E lacks. In practical terms, the i5-10200H might be preferable in systems where DDR3 support is required, or where the higher base clock provides perceived responsiveness in lightly loaded scenarios. However, benchmark results show the i5-1145G7E outperforms it even in single-core tests, so the higher base clock does not translate into real-world wins.
