Intel Core i3-9100 vs Intel Core i5-7600 Comparison

Head-to-Head Benchmarks

The benchmark data presents a surprisingly split picture between these two four-core, four-thread desktop processors. Across eight recorded tests, the Intel Core i3-9100 takes five wins, while the Intel Core i5-7600 counters with three, but the margins tell a more nuanced story than the win count alone.

In the Cinebench suite, the i3-9100 consistently edges ahead, though by very narrow margins. In Cinebench R15 multi-core, the i3-9100 scores 566 against the i5-7600's 563, a delta of -0.5 percent. The single-core R15 test is a dead heat at 79 points for both chips, with the tie awarded to the i5-7600 in the database. Moving to Cinebench R20, the i3-9100 leads again in multi-core with 2361 versus 2348 (a -0.6 percent delta) and in single-core with 333 versus 331 (also -0.6 percent). The R23 results mirror this pattern: the i3-9100 posts 5622 in multi-core against 5591, and 793 in single-core against 789, both deltas at -0.5 or -0.6 percent.

The Geekbench tests flip the script decisively. Here, the i5-7600 wins multi-core with 3704 against the i3-9100's 3403, a substantial 8.8 percent advantage. In single-core Geekbench, the i5-7600 scores 1344 versus 1290, a 4.2 percent lead. These are the largest deltas in the entire head-to-head comparison, and they suggest that the i5-7600 has a meaningful edge in the workloads Geekbench exercises, particularly in multi-threaded scenarios where it leads by nearly nine percent.

The overall average benchmark score favors the i5-7600, which sits at 1844 compared to the i3-9100's 1806. Both processors occupy the same 42nd percentile among all CPUs in the database, indicating they perform in a similar tier despite the differing test outcomes.

Looking at the nearest rivals for context, the i5-7600's average score of 1844 places it just 0.1 percent ahead of the Intel Core i7-8706G (1842), 0.5 percent ahead of the AMD Athlon Gold PRO 3150G (1836), and 0.7 percent ahead of both the AMD Ryzen 5 4600U and Intel Core i5-8305G (1832 and 1831 respectively). The i3-9100's 1806 average sits 0.1 percent behind the Intel Core i3-9320 (1808), 0.2 percent behind the AMD Ryzen 5 PRO 4650U (1810), 0.2 percent ahead of the Intel Xeon E5-1620 v4 (1802), and 0.5 percent behind the Intel Core i5-6600K (1816). These rival positions confirm that both chips are tightly clustered in the same performance neighborhood, with the i5-7600 holding a slight overall edge.

The Verdict

The data points to a clear if narrow conclusion: the Intel Core i5-7600 is the better overall performer, primarily due to its commanding lead in Geekbench tests. The 8.8 percent multi-core advantage and 4.2 percent single-core advantage in Geekbench are the largest margins in the entire comparison, and they outweigh the i3-9100's repeated but tiny Cinebench wins, which never exceed 0.6 percent.

For users whose workloads resemble Geekbench's patterns, which tend to emphasize memory-sensitive and integer-heavy tasks, the i5-7600 is the stronger choice. The i3-9100, by contrast, offers marginal improvements in Cinebench rendering scenarios, but the differences are so small as to be practically indistinguishable in real-world use. A 0.5 to 0.6 percent delta is within run-to-run variance territory.

From a production standpoint, the i5-7600 remains listed as active, while the i3-9100 is marked end-of-life. This gives the i5-7600 an availability advantage for new builds. The i3-9100 does support ECC memory, which the i5-7600 does not, making it the only choice for users who require error-correcting memory. For everyone else, the i5-7600's superior Geekbench scores and active production status make it the more compelling pick.

Architecture Differences

The two processors come from different Intel architecture generations. The i5-7600 is built on Kaby Lake, while the i3-9100 uses Coffee Lake, specifically the Coffee Lake Refresh generation. Both are manufactured on Intel's 14 nm process node at the same foundry, so the underlying transistor technology is identical.

The integrated graphics differ between the two. The i5-7600 carries HD 630 graphics, while the i3-9100 features UHD Graphics 630. The UHD branding typically denotes a slightly newer graphics implementation, though the database records no performance numbers for either iGPU.

A notable architectural difference is ECC memory support. The i3-9100 supports ECC memory, while the i5-7600 does not. This is a functional distinction that can matter for workstation or server-adjacent builds where data integrity is paramount.

The die size is recorded only for the i3-9100 at 126 mm². The database does not list a die size for the i5-7600, so no direct comparison of physical dimensions is possible.

Both processors share the same cache hierarchy: 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3 cache. This means the memory architecture in terms of cache capacity is identical, which helps explain why the Cinebench results are so close.

Specification Differences

The recorded specifications show several differences between the two chips, though the core configuration is identical. Both have 4 cores and 4 threads, both use the Intel Socket 1151, both have a 65 W TDP, and both support DDR4 memory in dual-channel configuration with 38.4 GB/s bandwidth. PCIe connectivity is also the same: Gen 3 with 16 lanes from the CPU.

The base clock differs: the i5-7600 runs at 3.50 GHz, while the i3-9100 runs at 3.60 GHz, a 0.1 GHz advantage for the newer chip. The boost clock similarly favors the i3-9100 at 4.20 GHz versus 4.10 GHz. These higher clocks likely explain the i3-9100's slight edge in Cinebench tests, which are scaling-bound and benefit from raw frequency.

The release dates are about 20 months apart. The i5-7600 launched on 2017-01-02, while the i3-9100 launched on 2018-08-31. The i5-7600 has the part number SR334, and the i3-9100 is SRCZV.

The i3-9100 has a recorded launch MSRP of $122. The i5-7600 has no launch MSRP in the database, so no price comparison is possible.

Production status differs: the i5-7600 is active, while the i3-9100 is end-of-life. This means the i5-7600 is still in production, while the i3-9100 has been discontinued.

Neither processor has an unlocked multiplier, so both are locked for overclocking. The market segment for both is Desktop, and both are manufactured by Intel.
