Intel Core i3-13100 vs Intel Core i7-9700 Comparison

The Verdict

The recorded data presents a clear generational contrast. The Intel Core i3-13100 wins 13 of the 17 head-to-head benchmark comparisons, while the Intel Core i7-9700 takes only 4. Despite having half the physical cores, the newer i3-13100 leads in nearly every Cinebench test and in the majority of Passmark workloads. The i7-9700 retains advantages only in specific memory-heavy or vectorized tasks.

For users prioritizing single-thread performance, modern platform features, and encryption workloads, the i3-13100 is the stronger choice based on the data. Its 25.5% lead in Passmark single-thread scores and 7% advantage across all Cinebench single-core tests are decisive. The i3-13100 also matches the i7-9700 in overall percentile ranking, both sitting at the 72nd percentile among all CPUs.

The i7-9700 remains relevant for workloads that exploit its eight physical cores and larger per-core L2 cache. It wins in data compression by 11%, extended instructions by 23.7%, floating-point math by 5.4%, and random string sorting by 32.2%. Users running those specific task types may find the older chip preferable, but the i3-13100 is the more broadly competitive processor in the benchmark database.

Architecture Differences

The two processors come from different design eras. The i3-13100 uses Raptor Lake architecture on a 10 nm process with a die size of 163 mm². The i7-9700 uses Coffee Lake architecture on a 14 nm process with a die size of 180.3 mm². This process advantage contributes to the i3-13100's higher efficiency per clock.

Core counts differ significantly. The i3-13100 has 4 cores and 8 threads, relying on Hyper-Threading. The i7-9700 has 8 cores and 8 threads, with no simultaneous multithreading. This explains why the i7-9700 wins in tasks that scale with raw core count, such as data compression and extended instruction workloads.

Cache layouts differ notably. The i3-13100 has 80 KB of L1 per core and 1.25 MB of L2 per core, while the i7-9700 has 64 KB of L1 per core and only 256 KB of L2 per core. Both share 12 MB of L3, but the i3-13100's larger per-core L2 gives it a latency advantage in single-threaded operations. The i7-9700's L2 is four times smaller per core, which likely contributes to its lower single-thread scores.

Clock speeds tell a similar story. The i3-13100 has a 3.40 GHz base clock and a 4.50 GHz boost clock. The i7-9700 has a 3.00 GHz base clock but a slightly higher 4.70 GHz boost. Despite the lower boost ceiling, the i3-13100 achieves better single-thread results in every recorded benchmark, suggesting architectural efficiency outweighs the raw clock advantage.

Memory and platform support differ substantially. The i3-13100 supports both DDR4 and DDR5 memory, while the i7-9700 is limited to DDR4. The i3-13100 uses PCIe Gen 5 with 16 CPU lanes, whereas the i7-9700 uses PCIe Gen 3 with 16 lanes. The i7-9700 has a recorded memory bandwidth of 42.7 GB/s, a figure not available for the i3-13100 in the database. The i3-13100 uses Intel Socket 1700, while the i7-9700 uses the older Intel Socket 1151. Integrated graphics differ as well: UHD Graphics 730 on the i3-13100 versus UHD Graphics 630 on the i7-9700.

Production status separates the two further. The i3-13100 is listed as Active, while the i7-9700 is End-of-life. The i3-13100 released in January 2023, nearly four years after the i7-9700's April 2019 release. The launch MSRP for the i3-13100 was $134, while the i7-9700 launched at $333. Neither processor has an unlocked multiplier.

Where Each One Wins

The i3-13100 dominates in single-thread workloads. Its Passmark single-thread score of 3460 versus 2756 for the i7-9700 represents a 25.5% advantage, the largest margin in any benchmark between the two. All six Cinebench tests, covering both single-core and multi-core variants, go to the i3-13100 with margins between 6.9% and 7.1%. The i3-13100 also wins in data encryption by a massive 86.2%, a result driven by newer AES instruction support.

The i3-13100 also leads in multi-threaded synthetic tests despite its 4-core design. Passmark multithread shows 13726 versus 13223 for a 3.8% win. Integer math goes to the i3-13100 by 2.9%, and physics simulation by 6.1%. Prime number finding shows an 8.3% advantage for the newer chip. These results indicate that the i3-13100's 8 threads, combined with higher IPC, compensate for the i7-9700's extra physical cores.

The i7-9700 wins in four specific areas. Random string sorting shows its largest victory at 32.2%, scoring 23482 versus 15925.
