Intel Core i5-7400 vs Intel Core i7-13700E Comparison

The Intel Core i7-13700E and Intel Core i5-7400 are desktop processors from different generations of Intel's lineup. The i7-13700E is a 16-core Raptor Lake part with 24 threads, while the i5-7400 is a 4-core Kaby Lake chip with 4 threads. Benchmark results from the database show a decisive performance gap, with the i7-13700E winning every head-to-head comparison.

The Verdict

For any workload that scales with core count, the i7-13700E is the clear choice. It wins all eight head-to-head benchmarks, with multi-core deltas exceeding 500% in Cinebench R15, R20, and R23. The single-core advantage is also substantial, ranging from 133.7% in Geekbench to 502.2% in Cinebench R20. The i5-7400, despite its 63rd percentile ranking, is outclassed in every measured metric.

The i7-13700E also brings modern platform features: DDR4 and DDR5 memory support, PCIe Gen 5, ECC memory, and an unlocked multiplier. The i5-7400 is limited to DDR4, PCIe Gen 3, no ECC, and a locked multiplier. For anyone building a new system, the data points squarely to the i7-13700E. The i5-7400 remains relevant only for legacy systems or tasks that do not benefit from additional cores.

Context from the database reinforces this. The i7-13700E has an average benchmark score of 7957, placing it in the 64th percentile of all CPUs, with its nearest rival being the AMD EPYC 7551P at 7952 (0.1% difference). The i5-7400 averages 7469, ranking in the 63rd percentile, with the Intel Core i5-4570 as its closest competitor at 7421 (0.6% difference). The i7-13700E sits slightly higher in the overall distribution, but the head-to-head results show a far larger gap than the percentile difference suggests.

Architecture Differences

The two processors come from different architectural eras. The i7-13700E is built on Raptor Lake, using Intel's 10 nm process, while the i5-7400 is Kaby Lake on 14 nm. The i7-13700E has a die size of 257 mm², while the i5-7400's die size is not recorded in the database.

The core configuration differs dramatically. The i7-13700E packs 16 cores and 24 threads, while the i5-7400 has 4 cores and 4 threads. Cache hierarchies also diverge. The i7-13700E has 80 KB of L1 per core, 2 MB of L2 per core, and 30 MB of shared L3. The i5-7400 has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3.

Memory support is another major split. The i7-13700E supports both DDR4 and DDR5, while the i5-7400 is limited to DDR4. The i7-13700E also features PCIe Gen 5 with 16 lanes, whereas the i5-7400 uses PCIe Gen 3 with 16 lanes. Integrated graphics differ as well: the i7-13700E has UHD Graphics 770, while the i5-7400 has HD 630. ECC memory support is present on the i7-13700E but absent on the i5-7400. The i7-13700E has an unlocked multiplier, while the i5-7400 is locked. These architectural differences explain the large performance gap seen in benchmarks.

Head-to-Head Benchmarks

The i7-13700E wins all eight head-to-head benchmarks. The largest multi-core advantage appears in Cinebench R15 multi-core, where the i7-13700E scores 2816 against 469, a 500.4% delta. Cinebench R20 multi-core shows 11735 vs 1956, a 499.9% delta. Cinebench R23 multi-core shows 27941 vs 4658, a 499.8% delta. Geekbench multi-core shows 12728 vs 2740, a 364.5% delta.

Single-core results are also lopsided. Cinebench R15 single-core: 397 vs 66, a 501.5% delta. Cinebench R20 single-core: 1656 vs 275, a 502.2% delta. Cinebench R23 single-core: 3944 vs 657, a 500.3% delta. Geekbench single-core: 2437 vs 1043, a 133.7% delta. The i5-7400 does not win any of the eight comparisons.

The multi-core deltas of roughly 500% indicate that the i7-13700E delivers about six times the multi-threaded performance in Cinebench workloads. The single-core advantage is smaller but still substantial, ranging from 133.7% in Geekbench to over 500% in Cinebench R20. These results align with the core count and architecture differences. The i7-13700E's 16 cores and 24 threads, combined with a 5.10 GHz boost clock, overwhelm the i5-7400's 4 cores and 3.50 GHz ceiling. The cache hierarchy, with 30 MB of shared L3 versus 6 MB, further contributes to the gap. For any application that can use multiple threads, the i7-13700E is the definitive winner. Even in single-threaded tasks, the newer architecture and higher clock speed provide a decisive edge.
