Intel Core i5-1145G7E vs Intel Core i7-10710U Comparison

Head-to-Head Benchmarks

The recorded data shows a remarkably consistent performance profile for these two mobile processors. The Intel Core i7-10710U wins all six head-to-head Cinebench comparisons, but the margins are narrow, ranging from 3.4% to 3.8%. This is not a lopsided victory in real-world terms; it is a systematic but modest advantage across every workload tested.

In the Cinebench R15 multicore test, the i7-10710U scores 783 against 757 for the i5-1145G7E, a 3.4% lead. The single-core R15 result is slightly more favorable to the i7, with 110 points versus 106, a 3.8% delta. Moving to Cinebench R20, the multicore score is 3265 for the i7-10710U and 3156 for the i5-1145G7E, again a 3.5% difference. The single-core R20 result shows 460 versus 445, a 3.4% gap. In the latest Cinebench R23, the multicore scores are 7774 and 7516, a 3.4% difference, while single-core results are 1097 and 1061, also 3.4% apart.

The consistency of these deltas is notable. Every single benchmark, regardless of generation or core-count sensitivity, lands within a 3.4% to 3.8% window. This indicates that the performance gap is not workload-dependent; it is a uniform characteristic of the two chips' execution capabilities. The i7-10710U does not dramatically outpace its rival in any specific test, nor does it fall behind in any. It simply maintains a steady, small advantage across the board.

The average benchmark score for the i7-10710U is 2248, placing it at the 47th percentile of all CPUs in the database. The i5-1145G7E averages 2174, also at the 47th percentile. This means both processors sit in the same performance tier relative to the broader market, despite the i7's consistent head-to-head wins. The nearest rival for the i7-10710U is the AMD Ryzen 5 PRO 1500 with an average score of 2246, a delta of just 0.1%. For the i5-1145G7E, the closest competitor is the AMD Ryzen 5 3400GE at 2175, a delta of 0%. These reference points underscore that both Intel chips are clustered with mid-range desktop and mobile parts from a few generations back.

Architecture Differences

The two processors come from different Intel microarchitectures and manufacturing nodes. The i7-10710U is built on Comet Lake, a 14 nm process, while the i5-1145G7E uses Tiger Lake on a 10 nm node. This generational gap is significant. The i5-1145G7E benefits from a newer transistor design, which typically allows for higher efficiency per clock, but the i7-10710U compensates with a higher core count.

Core and thread counts differ substantially. The i7-10710U has 6 cores and 12 threads, while the i5-1145G7E has 4 cores and 8 threads. This gives the i7 a 50% advantage in physical cores and a 50% advantage in logical threads. Despite this, the multicore benchmark deltas are only around 3.4%, suggesting that the i5's newer architecture nearly closes the gap that the extra cores provide.

Clock speeds also differ. The i7-10710U has a base clock of 1100 MHz and a boost clock of 4.70 GHz. The i5-1145G7E has a higher base clock of 1500 MHz but a lower boost of 4.10 GHz. The i7's higher boost clock likely contributes to its single-core wins, while the i5's higher base clock helps it maintain performance under sustained loads. The i7-10710U has a TDP of 25 W, while the i5-1145G7E is rated at 28 W. The i5 consumes slightly more power, which may reflect its newer process node running at higher base frequencies.

Cache hierarchies are markedly different. The i7-10710U has 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3 cache. The i5-1145G7E has 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3. The i5 has larger per-core L1 and L2 caches, which can reduce latency for frequently accessed data. The i7 has a larger L3 pool, which benefits multi-threaded workloads where shared data is accessed by multiple cores.

Memory support also diverges. The i7-10710U supports DDR3 and DDR4, while the i5-1145G7E supports DDR4 and LPDDR4X. The i5 additionally specifies a dual-channel memory bus, whereas the i7 does not list a memory bus configuration. The i5 also features PCIe Gen 4 with 4 lanes for the CPU, while the i7 does not list any PCIe specification. The integrated graphics differ as well: the i7 uses UHD Graphics, while the i5 uses Iris Xe Graphics G7 with 80 execution units. The i5's die size is listed at 144 mm², while the i7's die size is not recorded.

The i7-10710U was released on 2019-08-20 and is end-of-life. The i5-1145G7E was released on 2020-09-01 and remains active. The i5 has a part number (SRK0Z) and a launch MSRP of $312, while the i7 has neither a part number nor a listed MSRP. Both processors use Intel BGA sockets, but the i7 uses BGA 1440 and the i5 uses BGA 1449, so they are not socket-compatible.

Where Each One Wins

The i7-10710U wins every recorded benchmark, so the use-case split is defined by the degree of its advantage rather than by any reversal. The data shows the i7 leads by 3.8% in Cinebench R15 single-core, its largest margin, and by 3.4% in the other five tests. This suggests that the i7 is marginally better for both lightly threaded and heavily threaded workloads, but the difference is small enough that most users would not perceive it in daily tasks.

For multi-threaded rendering or content creation, the i7's 6-core, 12-thread configuration provides a theoretical advantage, but the benchmark results show only a 3.4% to 3.5% lead over the 4-core, 8-thread i5. This means that the i5's newer Tiger Lake architecture with its larger per-core caches and higher base clock largely offsets the core-count deficit. In practical terms, both processors deliver similar multi-core performance, with the i7 maintaining a slight edge.

For single-threaded tasks, the i7's higher boost clock of 4.70 GHz versus 4.10 GHz for the i5 gives it the lead. The 3.8% delta in R15 single-core and 3.4% in R20 and R23 single-core are consistent. This makes the i7 marginally better for applications that rely on a single fast core, such as legacy software or lightly threaded games. However, the i5's higher base clock and newer architecture narrow the gap.

The i5-1145G7E does not win any benchmark, but it has characteristics that may favor certain deployments. Its newer 10 nm process, active production status, and PCIe Gen 4 support make it a more modern platform choice for new designs. Its larger L2 cache per core (1.25 MB versus 256 KB) and larger L1 cache (80 KB versus 64 KB) may provide lower latency in cache-sensitive workloads, even if the aggregate Cinebench scores do not reflect a win. The i5 also supports LPDDR4X memory, which is common in thin-and-light laptops, and its Iris Xe Graphics with 80 EUs is likely more capable than the i7's UHD Graphics, though no graphics benchmarks are recorded.

The i7-10710U is the better choice if maximizing the recorded CPU benchmark scores is the sole criterion. The i5-1145G7E is the better choice for a newer platform with active production status, modern memory support, and a more advanced process node, accepting a small performance deficit.
