Intel Core i3-13100E vs Intel Core i7-8086K Comparison

Head-to-Head Benchmarks

The recorded data presents a fascinating generational clash. Across the eight benchmark tests, the Intel Core i7-8086K claims seven wins, while the Intel Core i3-13100E takes one decisive victory. The margins, however, tell the more compelling story.

In the Cinebench suite, the i7-8086K consistently edges out the i3-13100E by a narrow margin. The multicore test in Cinebench R15 shows the i7-8086K scoring 1206 against the i3's 1180, a 2.2% advantage. The single-core test in the same suite is similar, with the i7-8086K winning 170 to 166, a 2.4% gap. This pattern repeats across Cinebench R20 and R23. The R20 multicore result is 5029 versus 4918, a 2.3% lead, while the single-core result is 709 versus 694, another 2.2% margin. The R23 multicore test shows 11975 against 11710, and the single-core test shows 1690 versus 1653, both hovering around that same 2.2% to 2.3% range.

The i7-8086K's biggest win comes in Geekbench multicore, where it scores 7920 compared to the i3-13100E's 7025. That is a 12.7% gap, the largest margin in either direction across the entire comparison. The additional two cores and four threads on the i7-8086K clearly pay dividends in this workload.

The i3-13100E's sole victory is a significant one. In Geekbench single-core, it scores 2001 against the i7-8086K's 1697. The delta is 15.2% in favor of the i3, making it the largest single-core margin of the matchup. This is a substantial generational improvement in IPC and clock efficiency, even if the older chip holds its ground elsewhere.

Looking at the aggregate picture, the i7-8086K has an average benchmark score of 3800 across all recorded tests, placing it in the 56th percentile of all CPUs. The i3-13100E averages 3668, also landing in the 56th percentile. The i7-8086K's nearest rivals in the database include the Intel Core i7-9700KF at 3787, a 0.3% difference, and the AMD Ryzen 9 4900H at 3820, a 0.5% gap in the other direction. The i3-13100E sits close to the AMD EPYC 7251, which averages 3671, a 0.1% difference, and the AMD Ryzen 7 PRO 1700X at 3673.

The benchmark results indicate that the i7-8086K is the stronger overall performer in most threaded workloads, but the i3-13100E delivers a clear single-threaded punch that the older architecture cannot match.

Where Each One Wins

The use-case split is relatively straightforward based on the recorded data. The i7-8086K wins all three Cinebench multicore tests, plus the three Cinebench single-core tests, plus Geekbench multicore. That is seven wins out of eight possible tests. The i3-13100E wins only Geekbench single-core.

For users running Cinebench renders, the i7-8086K is the better choice. Its multicore scores are consistently higher across R15, R20, and R23, with margins from 2.2% to 2.3%. The i7-8086K also dominates Geekbench multicore with a 12.7% advantage, which suggests it handles heavily threaded workloads with more competence.

The i3-13100E is the pick for single-threaded Geekbench tasks. Its score of 2001 versus 1697 represents a 15.2% improvement, which is the largest delta in the entire comparison. For workloads that depend entirely on single-core performance, such as certain legacy applications or lightly threaded games, the i3-13100E offers a meaningful edge.

The i7-8086K's wins in Cinebench single-core tests are narrow, only 2.2% to 2.4%, which means the i3-13100E is not far behind in those scenarios. The Geekbench single-core result, however, shows a different story, one where the i3-13100E clearly takes the lead.

The i3-13100E also has advantages beyond raw benchmark scores. It supports ECC memory, a feature the i7-8086K lacks entirely. It also supports both DDR4 and DDR5 memory, while the i7-8086K is limited to DDR4. The i3-13100E has PCIe Gen 5 connectivity with 16 lanes, while the i7-8086K uses PCIe Gen 3 with the same lane count.

Architecture Differences

The two processors come from different eras of Intel's design roadmap. The i7-8086K is built on Coffee Lake, a 14 nm process from the Core i7 40th generation. The i3-13100E uses Raptor Lake, a 10 nm process from the Core 13th Gen series. The i3-13100E also has a recorded die size of 163 mm², while no die size is listed for the i7-8086K.

Core and thread counts differ significantly. The i7-8086K has 6 cores and 12 threads, while the i3-13100E has 4 cores and 8 threads. Despite having fewer cores, the i3-13100E manages to stay competitive in multicore tests, which points to architectural efficiency gains in the newer design.

Clock speeds tell a similar story. The i7-8086K has a base clock of 4.00 GHz and a boost clock of 5.00 GHz. The i3-13100E runs at 3.30 GHz base and 4.40 GHz boost. The i7-8086K's higher clock speeds help it maintain leads in Cinebench tests, while the i3-13100E's newer architecture delivers the Geekbench single-core win despite lower clocks.

Cache layouts differ as well. The i7-8086K has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 12 MB of shared L3 cache. The i3-13100E has 80 KB of L1 cache per core and a much larger 1.25 MB of L2 cache per core, also with 12 MB of shared L3 cache. The larger per-core L2 cache on the i3-13100E is a notable architectural upgrade.

The i7-8086K has an unlocked multiplier, allowing overclocking, while the i3-13100E is locked. The i7-8086K draws 95 W TDP, while the i3-13100E draws 60 W. The i3-13100E also has a different integrated GPU, the UHD Graphics 730, compared to the UHD Graphics 630 on the i7-8086K.

Memory bandwidth is listed for the i7-8086K at 42.7 GB/s, while no figure is recorded for the i3-13100E. Both support dual-channel memory. The i3-13100E supports DDR4 and DDR5, while the i7-8086K supports only DDR4.

The production status differs as well. The i7-8086K is end-of-life, while the i3-13100E is active. Sockets are incompatible: the i7-8086K uses Intel Socket 1151, and the i3-13100E uses Intel Socket 1700.
