Intel Core i3-9100E vs Intel Core i5-5675R Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core i3-9100E and the Intel Core i5-5675R is remarkably one-sided. Across all six recorded Cinebench tests, the i3-9100E claims victory every time, with winsA recorded at 6 and winsB at 0. The margins are consistent, hovering around the 17% mark across both single-core and multi-core workloads.

Starting with multi-core performance, the i3-9100E posts a Cinebench R15 score of 559 against the i5-5675R's 476, a delta of 17.4%. The pattern repeats in R20, where the i3-9100E scores 2330 versus 1987, a 17.3% advantage. In R23 multi-core, the i3-9100E reaches 5549 while the i5-5675R manages 4733, yielding a 17.2% gap. These numbers tell a clear story: the newer Coffee Lake architecture delivers a substantial lead in threaded workloads, even though both chips have the same core and thread count.

Single-core results follow the same trajectory. In Cinebench R15 single-core, the i3-9100E scores 78 against 67, a 16.4% edge. R20 single-core shows 328 versus 280, a 17.1% advantage. R23 single-core lands at 783 versus 668, again 17.2% ahead. The consistency of these deltas, ranging from 16.4% to 17.4%, suggests a structural advantage in instructions per clock rather than a workload-specific quirk.

The average benchmark score in the database tells a slightly different story. The i5-5675R has an average score of 1648, while the i3-9100E sits at 1605. This is because the i5-5675R's database record includes Geekbench results, which are not present for the i3-9100E. In the Geekbench tests, the i5-5675R scores 3738 multi-core and 1234 single-core. When only the shared Cinebench tests are considered, the i3-9100E leads by roughly 17% across the board.

Percentile rankings are close: the i3-9100E sits at the 39th percentile of all CPUs, while the i5-5675R sits at the 40th. This near parity in overall standing, despite the large head-to-head deltas, reflects the different benchmark mixes in each record. For users comparing only these two chips, the Cinebench suite provides the more direct apples-to-apples view.

Architecture Differences

The two processors belong to different architectural generations despite sharing the same 14 nm process node. The i3-9100E is built on Coffee Lake, specifically the Coffee Lake Refresh generation, while the i5-5675R uses the older Broadwell architecture. Both are manufactured by Intel, but the die sizes differ substantially: the i3-9100E measures 126 mm², whereas the i5-5675R is larger at 182 mm². The larger Broadwell die reflects its more complex integrated graphics and older design methodology.

Core and thread counts are identical at 4 cores and 4 threads. Base clocks match exactly at 3.10 GHz for both. The boost clock differs slightly: the i3-9100E reaches 3.70 GHz, while the i5-5675R tops out at 3.60 GHz. This 0.10 GHz gap contributes to the single-core performance lead, though the architecture generation plays a larger role.

Cache hierarchies diverge in the L3 tier. The i3-9100E has 6 MB of shared L3 cache, while the i5-5675R has only 4 MB. L1 and L2 caches are identical at 64 KB per core and 256 KB per core, respectively. The larger L3 on the Coffee Lake part helps explain its multi-core advantage in cache-sensitive workloads.

Memory support is a clear differentiator. The i3-9100E supports DDR4 memory with a dual-channel bus and 38.4 GB/s of bandwidth. The i5-5675R uses DDR3, also dual-channel, but with a lower 29.9 GB/s peak bandwidth. This 8.5 GB/s difference in theoretical memory throughput favors the newer platform. The i3-9100E also supports ECC memory, while the i5-5675R does not, a relevant factor for reliability-focused builds.

Integrated graphics differ as well. The i3-9100E carries UHD Graphics 630, while the i5-5675R features Iris Pro Graphics 6200. The Broadwell part's larger die is partly due to its beefier GPU block, which historically offered strong integrated graphics performance. However, the database does not include graphics benchmarks, so any comparison must remain qualitative.

The i3-9100E uses Intel Socket 1151, while the i5-5675R uses Intel BGA 1364, meaning the latter is soldered to the board rather than socketed. The i3-9100E is marked as end-of-life production, while the i5-5675R remains active. Their release dates are far apart: the i5-5675R launched in May 2015, and the i3-9100E arrived in August 2018, a gap of over three years.

The Verdict

The data points decisively toward the Intel Core i3-9100E for raw compute performance. It wins every Cinebench test by margins between 16.4% and 17.4%, a consistent and sizable lead. The newer Coffee Lake architecture, higher boost clock, larger L3 cache, and faster DDR4 memory support all contribute to this outcome. For users prioritizing CPU-bound tasks like rendering, encoding, or compilation, the i3-9100E is the clear choice based on benchmark results.

The i5-5675R does have its own strengths in the database, though they are not computational. Its average benchmark score of 1648 is higher than the i3-9100E's 1605, but that figure includes Geekbench results absent from the i3-9100E record. In the shared Cinebench suite, the i3-9100E dominates. The i5-5675R's Iris Pro Graphics 6200 may offer better integrated graphics capabilities, but no graphics benchmarks are recorded to quantify this.

The i5-5675R remains active in production, while the i3-9100E is end-of-life. This could matter for long-term availability or replacement sourcing. However, for pure processing power, the recorded measurements leave no ambiguity. The i3-9100E's percentile ranking of 39 versus the i5-5675R's 40 is essentially a wash in the broader CPU landscape, but head-to-head, the newer part wins outright.

Where Each One Wins

The Intel Core i3-9100E wins in every recorded Cinebench benchmark, covering both single-core and multi-core variants across R15, R20, and R23. Its margins range from 16.4% in R15 single-core to 17.4% in R15 multi-core. The i3-9100E also wins on architectural features: larger L3 cache, DDR4 memory support, ECC capability, and a higher boost clock. For users running CPU-intensive applications such as video rendering, software compilation, or scientific simulations, the benchmark deltas translate directly into shorter completion times.

The Intel Core i5-5675R has no benchmark wins in the head-to-head comparison. However, it does hold advantages in other recorded areas. Its average benchmark score of 1648 is higher than the i3-9100E's 1605, though this is influenced by the inclusion of Geekbench scores in its record. The i5-5675R's die size of 182 mm² houses Iris Pro Graphics 6200, which may offer superior integrated graphics performance, though no graphics benchmarks are available to confirm this. The i5-5675R is also listed as active production, whereas the i3-9100E is end-of-life, which could affect availability for new system builds. Its BGA 1364 socket means it is permanently attached to the motherboard, which some users may prefer for compact or embedded designs.
