Intel Core i5-1145G7E vs Intel Core i7-1068NG7 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Core i7-1068NG7 across every Cinebench iteration tested. In Cinebench R15 multi-core, the i7-1068NG7 scores 787 against 757 for the i5-1145G7E, a 4% advantage. The single-core R15 result follows the same pattern: 110 versus 106, a 3.8% lead. Moving to Cinebench R20, the margin holds steady: multi-core shows 3280 against 3156, a 3.9% gap, while single-core shows 462 against 445, again 3.8%.

The most demanding workload, Cinebench R23, mirrors the earlier results. The i7-1068NG7 posts 7810 in multi-core versus 7516 for the i5-1145G7E, a 3.9% difference. Single-core R23 sees 1102 versus 1061, another 3.9% lead. Across all six head-to-head benchmarks, the i7-1068NG7 wins outright with no ties or losses. The margins are consistent, ranging from 3.8% to 4%, which suggests a steady performance differential rather than workload-specific outliers.

In terms of aggregate standing, the i7-1068NG7 carries an average benchmark score of 2259, placing it in the 47th percentile of all CPUs. Its closest rival, the Intel Core i3-10305, scores 2264, a delta of -0.2%, meaning the i7-1068NG7 is essentially neck-and-neck with that desktop chip. The Intel Core i5-9400 trails at 2254, a 0.2% delta, while the Intel Core i7-10710U sits at 2248, a 0.5% delta. The AMD Ryzen 5 PRO 1500 rounds out the comparison at 2246, a 0.6% delta.

For the i5-1145G7E, the average benchmark score is 2174, also in the 47th percentile. Its nearest rival, the AMD Ryzen 5 3400GE, matches it exactly at 2175, a 0% delta. The Intel Core i7-1185GRE comes in at 2178, a -0.2% delta, while the Intel Core i5-7640X scores 2167, a 0.3% delta. The Intel Core i7-5950HQ trails at 2158, a 0.8% delta. The data shows both chips occupy the same percentile tier, but the i7-1068NG7 sits roughly 85 points higher on the average benchmark scale.

Architecture Differences

The two processors come from different Intel generations and use distinct core designs. The i7-1068NG7 is built on Ice Lake-U with the Sunny Cove microarchitecture, while the i5-1145G7E uses Tiger Lake-U with the Willow Cove microarchitecture. Both are fabricated on Intel's 10 nm process node, and both are produced in-house at Intel's foundry.

Die size differs notably: the i7-1068NG7 measures 123 mm², while the i5-1145G7E is larger at 144 mm². This larger die area for the Tiger Lake part likely accommodates the revised cache hierarchy and newer graphics block. Cache layouts are substantially different between the two. The i7-1068NG7 has 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. The i5-1145G7E ups the per-core L1 to 80 KB and the per-core L2 to 1.25 MB, while keeping the same 8 MB shared L3. The larger L2 per core on the Tiger Lake part is a notable architectural shift, though it does not translate into a benchmark win here.

Memory support differs as well. The i7-1068NG7 supports DDR4 only, while the i5-1145G7E supports both DDR4 and LPDDR4X. Both use dual-channel memory buses. The i7-1068NG7 has a rated memory bandwidth of 51.2 GB/s; the database does not list a bandwidth figure for the i5-1145G7E. PCIe support also diverges: the i7-1068NG7 uses Gen 3, while the i5-1145G7E supports Gen 4 with 4 lanes available on the CPU.

Integrated graphics differ as well. The i7-1068NG7 ships with Iris Plus graphics, while the i5-1145G7E includes Iris Xe Graphics G7 with 80 execution units. The newer Tiger Lake iGPU is a step up in capability, but the CPU benchmark data does not cover graphics performance.

Clock speeds are similar on paper. The i7-1068NG7 has a base clock of 2.30 GHz and a boost clock of 4.10 GHz. The i5-1145G7E lists a base clock of 1500.00 MHz (1.50 GHz) and the same 4.10 GHz boost. Both parts have a 28 W TDP, use four cores and eight threads, and lack an unlocked multiplier. Neither supports ECC memory.

Socket and package details also differ. The i7-1068NG7 uses Intel BGA 1344, while the i5-1145G7E uses Intel BGA 1449. The i7-1068NG7 is marked as end-of-life, with a release date of July 2019; the i5-1145G7E is still active, with a September 2020 release. Both are mobile-market parts.

The Verdict

The benchmark data is unambiguous: the Intel Core i7-1068NG7 outperforms the Intel Core i5-1145G7E in every recorded Cinebench test. The margins are narrow but consistent, ranging from 3.8% to 4% across multi-core and single-core workloads. The i7-1068NG7 holds a higher average benchmark score of 2259 compared to 2174 for the i5-1145G7E, a gap of roughly 85 points.

For users prioritizing raw CPU compute in Cinebench-style workloads, the i7-1068NG7 is the stronger pick. It also edges out the i5-1145G7E in both the R15 and R20 and R23 runs, making it the safer choice for multi-threaded rendering and single-threaded responsiveness. The i5-1145G7E, despite its newer architecture and larger die, does not convert those advantages into higher benchmark scores. Its larger L2 cache and newer Willow Cove cores may offer other benefits, but the recorded data does not reflect them in this test suite.

The i7-1068NG7 also benefits from being an end-of-life part with a higher launch MSRP of $320, but pricing is not a factor in this analysis. The i5-1145G7E is still active and carries a launch MSRP of $312. Both parts sit in the 47th percentile of all CPUs, meaning they are comparable to a broad swath of desktop and mobile processors, but neither is a standout in the overall CPU landscape.

The verdict from the data is simple: if you are choosing between these two solely on Cinebench performance, the i7-1068NG7 wins every test. The i5-1145G7E offers a newer platform and more modern features, but the performance delta is small and consistently favors the older part.

Where Each One Wins

The i7-1068NG7 wins every recorded Cinebench benchmark, so the use-case split is straightforward for compute-heavy tasks. In multi-core workloads like video rendering, 3D modeling, or batch photo processing, the i7-1068NG7 holds a 3.9% to 4% edge across R15, R20, and R23. That means shorter render times and faster completion of parallel tasks, though the margin is modest.

For single-core performance, which matters for everyday responsiveness, application launches, and lightly threaded games, the i7-1068NG7 again leads by 3.8% to 3.9% depending on the Cinebench version. The consistency of the lead suggests the i7-1068NG7 has a slight clock-for-clock advantage or better sustained boost behavior in these tests.

The i5-1145G7E does not win any of the six head-to-head benchmarks, but it does offer features that may matter outside of Cinebench. Its newer Tiger Lake architecture brings a larger L2 cache per core (1.25 MB versus 256 KB), which can aid workloads with high cache locality, though the database does not include such tests. It also supports LPDDR4X memory in addition to DDR4, and it has PCIe Gen 4 support with 4 CPU lanes, which is useful for fast NVMe storage or external GPU connectivity. The integrated Iris Xe Graphics G7 with 80 execution units is a newer design than the Iris Plus on the i7-1068NG7, potentially benefiting media playback or light gaming, though graphics benchmarks are not part of this data.

The i5-1145G7E is also an active production part, whereas the i7-1068NG7 is end-of-life. For new system designs, the i5-1145G7E offers a more current platform with ongoing availability. But for pure CPU compute, the recorded data leaves no ambiguity: the i7-1068NG7 is the faster chip. The i5-1145G7E is the better choice if you need the newer feature set, particularly LPDDR4X memory support or PCIe Gen 4 lanes, and you are willing to accept a small but consistent performance deficit in Cinebench workloads.
