Intel Core i5-1135G7 vs Intel Core i9-13900E Comparison

Intel Core i5-1135G7 and Intel Core i9-13900E represent opposite ends of Intel’s lineup: one is a low-power mobile processor for thin laptops, the other a desktop-class powerhouse for demanding workloads. The benchmark data shows a complete sweep for the i9-13900E across all eight head-to-head tests, but the size of that victory varies dramatically depending on the workload. The i5-1135G7 still holds relevance in its own domain, but the recorded measurements leave no doubt about which chip dominates raw performance.

Where Each One Wins

The Intel Core i9-13900E wins every benchmark category recorded in the database. There is no test where the Intel Core i5-1135G7 comes out ahead. The i9-13900E’s advantage is most pronounced in multi-threaded workloads, where its 24 cores and 32 threads produce scores that are multiples of the i5-1135G7’s results. Cinebench R23 multicore shows the i9-13900E scoring 34244 against 7909 for the i5-1135G7, a 76.9% gap in favor of the desktop chip. The same pattern holds in Cinebench R20 and R15 multicore tests.

The i5-1135G7, with 4 cores and 8 threads, is designed for efficiency and portability. Its wins, if any, would come from scenarios not captured in these benchmarks, such as battery life or thermal management. The data provided does not include any such measurements. In every recorded workload, from Geekbench single-core to Cinebench R15 multicore, the i9-13900E posts the higher score. The smallest margin between the two appears in Geekbench single-core, where the i9-13900E leads by 13.9%, a notable but far less dramatic difference than the multi-threaded gaps.

The i5-1135G7’s best relative showing is in single-threaded tests, where the core architecture matters more than core count. In Geekbench single-core, the i5-1135G7 scores 1417 against 1646 for the i9-13900E. The i9-13900E still wins, but the gap is much narrower than in multi-threaded tests. This suggests that for lightly threaded applications, the i5-1135G7 is less disadvantaged than one might expect from its core count alone.

Head-to-Head Benchmarks

The head-to-head data lists eight benchmark comparisons, and the Intel Core i9-13900E wins all eight. The most lopsided results come from Cinebench tests. In Cinebench R23 multicore, the i9-13900E scores 34244 against 7909 for the i5-1135G7, a delta of -76.9% from the perspective of the i5-1135G7. Cinebench R20 multicore shows a similar story: 14382 for the i9-13900E versus 3321 for the i5-1135G7, again a 76.9% gap. Cinebench R15 multicore repeats the pattern with 3451 versus 797.

Single-threaded Cinebench results follow the same trend but with a slightly larger percentage gap. Cinebench R15 single-core shows 487 for the i9-13900E and 112 for the i5-1135G7, a 77% difference. Cinebench R20 single-core shows 2030 versus 468, also a 76.9% gap. Cinebench R23 single-core shows 4834 versus 1116, a 76.9% gap. These numbers indicate that even in single-threaded workloads, the i9-13900E’s higher boost clock and newer architecture provide a substantial advantage.

Geekbench results are less extreme but still favor the i9-13900E. In Geekbench multicore, the i9-13900E scores 8337 against 3944 for the i5-1135G7, a 52.7% gap. In Geekbench single-core, the i9-13900E scores 1646 against 1417, a 13.9% gap. The single-core Geekbench result is the closest any test comes to a competitive race. The i9-13900E’s 5.20 GHz boost clock, compared to 4.20 GHz for the i5-1135G7, explains part of this edge.

Looking at the broader database context, both processors sit at the 65th percentile among all CPUs. The i5-1135G7 has an average benchmark score of 9053, while the i9-13900E averages 8676. This is counterintuitive given the head-to-head results, but it reflects the fact that the database averages scores across a wider range of tests, some of which may not be present in the head-to-head set. The i5-1135G7’s nearest rivals include the Intel Core i5-8350U (0.6% higher average score), Intel Xeon Gold 6346 (1.1% higher), Intel Xeon Gold 6330 (1.3% lower), and Intel Core i7-8650U (1.4% lower). The i9-13900E’s nearest rivals are the Intel Core i7-8565U (0.1% lower), Intel Core i5-8365U (0.4% higher), AMD EPYC 7601 (0.7% lower), and Intel Core i7-10510U (1.1% lower). These rival comparisons place both chips in similar overall standing, despite their divergent performance profiles.

Architecture Differences

The Intel Core i5-1135G7 uses the Tiger Lake architecture, specifically Tiger Lake-U, built on Intel’s 10 nm process. It belongs to the Willow Cove-U generation of Core i5 processors. The die size is 144 mm². The Intel Core i9-13900E uses Raptor Lake architecture, specifically Raptor Lake-S, also on a 10 nm process but with a larger die size of 257 mm². The i9-13900E belongs to the Raptor Lake generation of Core i9 processors.

Cache configurations differ substantially. The i5-1135G7 has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 8 MB of shared L3 cache. The i9-13900E also has 80 KB of L1 cache per core but doubles the L2 cache to 2 MB per core and increases shared L3 cache to 36 MB. The larger cache hierarchy on the i9-13900E supports its higher core count and more demanding workloads.

The i9-13900E supports ECC memory, while the i5-1135G7 does not. Memory support also differs: the i5-1135G7 supports DDR4 and LPDDR4X, while the i9-13900E supports DDR4 and DDR5. Both use dual-channel memory buses. The PCIe capabilities are distinct: the i5-1135G7 offers Gen 4 with 4 lanes (CPU only), while the i9-13900E offers Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well, with the i5-1135G7 featuring Iris Xe Graphics G7 80EU and the i9-13900E featuring UHD Graphics 770.

The market segments are opposite: the i5-1135G7 is a mobile processor using the Intel BGA 1449 socket, while the i9-13900E is a desktop processor using the Intel Socket 1700. The i5-1135G7 is end-of-life, while the i9-13900E remains active in production. Neither chip has an unlocked multiplier.

Specification Differences

The core and thread counts are the most obvious specification split. The i5-1135G7 has 4 cores and 8 threads, while the i9-13900E has 24 cores and 32 threads. Base clocks differ: 1500 MHz for the i5-1135G7 versus 1800 MHz for the i9-13900E. Boost clocks differ even more: 4.20 GHz versus 5.20 GHz. Thermal design power reflects the intended use cases, with the i5-1135G7 rated at 15 watts and the i9-13900E at 65 watts.

The sockets are incompatible, which is expected given the mobile and desktop segments. The i5-1135G7 uses Intel BGA 1449, while the i9-13900E uses Intel Socket 1700. Release dates differ by over two years: the i5-1135G7 launched in September 2020, and the i9-13900E launched in January 2023. The i5-1135G7 has a launch MSRP of $309, while the i9-13900E has no recorded launch MSRP in the database.

Part numbers also differ: SRK05 for the i5-1135G7 and SRMG2 for the i9-13900E. The i5-1135G7 is in the Core i5 series with no specific series name, while the i9-13900E is explicitly part of the Core 13th Gen series. The i5-1135G7’s generation is listed as Core i5 (Willow Cove-U), and the i9-13900E’s generation is Core i9 (Raptor Lake).

The Verdict

The data is unambiguous: the Intel Core i9-13900E outperforms the Intel Core i5-1135G7 in every recorded benchmark. For users who need maximum multi-threaded throughput, the i9-13900E is the only choice. Its 24 cores, 32 threads, 36 MB of L3 cache, and 5.20 GHz boost clock produce results that the i5-1135G7 cannot approach. Cinebench R23 multicore scores of 34244 versus 7909 illustrate the magnitude of the difference.

The i5-1135G7 is not without purpose. As a mobile chip with a 15 watt TDP, it targets thin-and-light laptops where power draw and heat are critical constraints. Its 4 cores and 8 threads are sufficient for everyday productivity, and its Geekbench single-core score of 1417 is respectable for its class. The i9-13900E, with a 65 watt TDP and desktop socket, is not a drop-in alternative for such systems.

For a desktop user assembling a workstation, the i9-13900E’s advantages in cache, core count, PCIe Gen 5 support, and ECC memory compatibility make it the obvious pick. For a mobile user prioritizing portability and battery life, the i5-1135G7 remains a viable option, provided the workload stays within its modest multi-threaded capabilities. The database records show no scenario where the i5-1135G7 beats the i9-13900E, but the two chips serve entirely different markets. Choose the i9-13900E for performance, choose the i5-1135G7 for mobility.
