Intel Core i5-13400E vs Intel Core i9-7980XE Comparison

Where Each One Wins

The recorded data draws a strikingly one-sided picture. Across every Cinebench iteration in the database, the Intel Core i9-7980XE takes the win, and it does so with remarkable consistency. The i9-7980XE wins all six head-to-head benchmark comparisons, while the Intel Core i5-13400E does not win a single one. That uniformity is unusual, especially when comparing processors from different eras.

The i9-7980XE’s advantage is most visible in multi-core workloads. Its Cinebench R23 multi-core score of 25072 outpaces the i5-13400E’s 22950 by 9.2%. The same pattern appears in Cinebench R20 multi-core, where the older chip scores 10530 versus 9639, again a 9.2% margin. Even in Cinebench R15 multi-core, the i9-7980XE leads with 2527 against 2313, a 9.3% difference.

Single-core results tell a similar story. The i9-7980XE scores 3539 in Cinebench R23 single-core, beating the i5-13400E’s 3240 by 9.2%. In Cinebench R20 single-core, the margin is 1486 versus 1360, a 9.3% lead. Cinebench R15 single-core follows with 356 against 326, another 9.2% win.

What does this mean in practice? The i9-7980XE is the stronger choice for any workload that scales with raw compute throughput, such as rendering, encoding, or heavy compilation tasks. The i5-13400E, despite its more modern architecture, does not surpass its older rival in any of the measured tests. There is no workload category in the database where the i5-13400E emerges as the better performer.

Architecture Differences

The two processors come from different architectural generations, and the database records substantial differences in their construction. The Intel Core i9-7980XE is built on the Skylake-X architecture, using a 14 nm process node. It belongs to the Core i9 Extreme (X-Series 7th Gen) generation and was released in 2017. Its die size is 484 mm², much larger than the newer chip.

The Intel Core i5-13400E uses the Raptor Lake architecture, specifically Raptor Lake-S, fabricated on a 10 nm process node. It belongs to the Core 13th Gen series and was released in 2023. Its die size is 215 mm², less than half the physical footprint of the Skylake-X part.

Core counts differ significantly. The i9-7980XE offers 18 cores and 36 threads, while the i5-13400E provides 10 cores and 16 threads. Cache layouts also diverge. The i9-7980XE has 64 KB of L1 cache per core, 1 MB of L2 per core, and 24.75 MB of shared L3 cache. The i5-13400E has 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The older processor therefore has a larger L3 pool, while the newer one has more L1 and L2 per core.

Memory support reflects their different platforms. The i9-7980XE supports DDR4 memory over a quad-channel bus, with a recorded memory bandwidth of 85.3 GB/s. The i5-13400E supports both DDR4 and DDR5 memory over a dual-channel bus, with no memory bandwidth figure recorded in the database. The i9-7980XE does not support ECC memory, while the i5-13400E does.

PCIe capabilities also differ. The i9-7980XE provides PCIe Gen 3 with 44 lanes from the CPU. The i5-13400E provides PCIe Gen 5 with 16 lanes from the CPU. The modern chip has a faster PCIe standard but far fewer lanes. The i9-7980XE has no integrated graphics, whereas the i5-13400E includes UHD Graphics 730.

Other notable differences: the i9-7980XE has an unlocked multiplier, the i5-13400E does not. The i9-7980XE carries a launch MSRP of $1999, while the i5-13400E has no recorded launch MSRP. The i9-7980XE is end-of-life, and the i5-13400E is active in production. Both use Intel sockets, but different ones: Socket 2066 for the older chip, Socket 1700 for the newer.

Head-to-Head Benchmarks

The benchmark data is notable for how tightly clustered the margins are. Every head-to-head comparison in the database shows the i9-7980XE winning by roughly 9.2% to 9.3%. This consistency suggests a fundamental performance gap rather than workload-specific variation.

In Cinebench R15 multi-core, the i9-7980XE scores 2527 against 2313 for the i5-13400E, a 9.3% advantage. Cinebench R15 single-core shows 356 versus 326, also 9.2% in favor of the older chip. These are the smallest absolute differences, but the proportional gap matches the other tests.

Cinebench R20 results follow the same shape. Multi-core: 10530 versus 9639, a 9.2% lead. Single-core: 1486 versus 1360, a 9.3% lead. The i9-7980XE maintains its edge even in single-threaded tests, which is notable because the i5-13400E has a higher boost clock of 4.60 GHz compared to 4.40 GHz on the i9-7980XE. Higher boost clock alone does not translate into a win here.

Cinebench R23, the most recent rendering workload in the database, repeats the pattern. Multi-core: 25072 versus 22950, a 9.2% margin. Single-core: 3539 versus 3240, a 9.2% margin. The i9-7980XE is ahead in every measured scenario, with no exceptions.

The database also records Geekbench scores for the i9-7980XE: 11198 multi-core and 1435 single-core. No corresponding Geekbench scores are recorded for the i5-13400E, so a direct comparison in that test is not possible.

The Verdict

The data leaves little room for ambiguity. The Intel Core i9-7980XE outperforms the Intel Core i5-13400E in every benchmark recorded in the database, despite being released years earlier and built on an older 14 nm process. Its wins range from 9.2% to 9.3% across all Cinebench tests, covering both single-core and multi-core workloads. The i9-7980XE’s 18 cores, 36 threads, and larger L3 cache give it a decisive edge in rendering tasks, as reflected in its higher Cinebench scores.

The i5-13400E is not without merits, but those merits do not show up in raw performance scores. It supports ECC memory, includes integrated graphics, uses a newer 10 nm process, and supports both DDR4 and DDR5 memory. It also has a higher boost clock at 4.60 GHz and a much lower TDP of 65 W compared to 165 W. None of these advantages translate into a benchmark win, however.

The i9-7980XE’s average benchmark score of 7018 places it in the 63rd percentile of all CPUs in the database, with nearest rivals including the Intel Xeon Platinum 8260 and AMD EPYC 7302P. The i5-13400E’s average score of 6638 places it in the 62nd percentile, with rivals such as the AMD Ryzen Threadripper 2950X and Intel Core i9-9940X. The i9-7980XE also holds a higher Geekbench multi-core score of 11198, though no Geekbench score is recorded for the i5-13400E.

For workloads where rendering performance is the priority, the i9-7980XE is the clear pick from the data. For those who need ECC memory support, integrated graphics, or a lower power envelope, the i5-13400E offers those features, but it does so without winning any performance comparison. Buyers should choose based on whether raw compute performance or platform features matter more, since the benchmark results consistently favor the older Extreme edition processor.
