Intel Core i3-9100TE vs Intel Core i5-8365UE Comparison

The Intel Core i3-9100TE and Intel Core i5-8365UE are both 14 nm quad-core parts, but they target entirely different segments of the market. The i3-9100TE is a desktop processor built for low-power embedded systems, while the i5-8365UE is a mobile chip designed for thin-and-light laptops. The benchmark data shows a clean sweep: the i5-8365UE wins every single recorded test. However, the margin of victory and the architectural context matter more than the binary win/loss record. The i5-8365UE leads by roughly 17% across all Cinebench workloads, a consistent advantage that stems from its higher boost clock and support for simultaneous multithreading. The i3-9100TE counters with a higher base clock, a socketed platform, and ECC memory support. Neither processor is a performance king; the i5 sits at the 36th percentile of all CPUs, and the i3 sits at the 37th, meaning both are firmly in entry-level territory.

Where Each One Wins

The head-to-head results are unambiguous: the i5-8365UE wins all six recorded benchmark comparisons. That includes every Cinebench iteration, from R15 through R23, in both single-core and multi-core tests. The i5-8365UE's multi-core advantage is particularly notable. In Cinebench R23 multicore, it scores 4710 against the i3-9100TE's 3900, a 17.2% lead. That advantage is not a fluke of a single test; it repeats consistently across R15, R20, and R23, with deltas ranging from 17.1% to 17.3%. The i5-8365UE also wins the single-core tests by nearly identical margins, posting 665 in Cinebench R23 single-core versus 550 for the i3-9100TE.

The i3-9100TE has no benchmark wins in this comparison. Its strengths lie outside raw compute. It is a desktop part on the Intel Socket 1151 platform, meaning it can be paired with a discrete motherboard and upgraded later. It also supports ECC memory, a feature absent from the i5-8365UE. The i5-8365UE, by contrast, is soldered to the board (Intel BGA 1528) and is listed as an active production part, while the i3-9100TE is end-of-life. For workloads like rendering or encoding that scale with threads, the i5-8365UE is the clear choice. For embedded systems requiring ECC and a replaceable CPU, the i3-9100TE has the edge, but the data cannot confirm a performance win for it.

Architecture Differences

Both chips share the same 14 nm process node from Intel, but they belong to different families. The i3-9100TE is Coffee Lake, specifically the Coffee Lake Refresh generation, and targets the desktop market. It has 4 cores and 4 threads, meaning no hyper-threading. Its base clock is 2.20 GHz with a boost of 3.20 GHz. The i5-8365UE is Whiskey Lake-U, a mobile-focused architecture. It also has 4 cores but doubles the thread count to 8, allowing each core to process two threads simultaneously. Its base clock is listed at 1600.00 MHz (1.60 GHz), but its boost clock reaches 4.10 GHz, a much higher ceiling than the i3's 3.20 GHz.

Cache configurations are identical on paper: 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. Both support dual-channel DDR4 memory with a theoretical bandwidth of 38.4 GB/s. PCIe connectivity is also the same, Gen 3 with 16 lanes from the CPU. The integrated graphics differ slightly: the i3-9100TE carries UHD Graphics 630, while the i5-8365UE has UHD Graphics 620. The i3-9100TE has a larger die at 126 mm², while the i5's die size is not recorded. The i3 is unlocked? No, the multiplier is locked on both parts.

The TDP gap is significant. The i3-9100TE is rated at 35 W, while the i5-8365UE is a 15 W part. That lower thermal envelope, combined with a higher boost clock, is a defining characteristic of the mobile chip. The i5-8365UE achieves better performance while drawing less power, at least according to the rated TDP figures. The i3-9100TE was released on March 31, 2019, and is now end-of-life. The i5-8365UE launched about two weeks later, on April 15, 2019, and remains active.

Head-to-Head Benchmarks

The largest recorded win for the i5-8365UE comes in Cinebench R23 single-core, where it scores 665 against the i3-9100TE's 550. That is a 17.3% delta, the widest margin in the entire comparison. The multi-core version of the same test shows a nearly identical gap: 4710 versus 3900, a 17.2% difference. Cinebench R20 mirrors this pattern. The i5-8365UE posts 279 in single-core to the i3's 231, a 17.2% lead, and 1978 in multi-core to the i3's 1638, also a 17.2% lead. Cinebench R15 shows the same story with slightly smaller margins: 66 versus 55 in single-core (16.7%) and 474 versus 393 in multi-core (17.1%).

The Geekbench results only exist for the i3-9100TE, so no direct comparison is possible there. The i3 scores 3214 in Geekbench multi-core and 1105 in single-core. The i5-8365UE has no recorded Geekbench scores in the database, so the head-to-head is limited to Cinebench. Still, the Cinebench data is consistent enough to draw conclusions. The i5-8365UE's 17% advantage in single-core tests indicates a higher effective per-core performance, which aligns with its 4.10 GHz boost clock versus the i3's 3.20 GHz. Its multi-core advantage matches the single-core advantage, suggesting that hyper-threading contributes little extra beyond the clock speed difference in these workloads, or that the 15 W thermal limit constrains simultaneous multi-threading gains.

Looking at the broader database context, the i5-8365UE has an average benchmark score of 1362, landing at the 36th percentile of all CPUs. Its nearest rivals include the Intel Core i5-6500T (identical average score of 1362, 0% delta), the Intel Core i7-3820QM (1366, -0.3%), the Intel Xeon D-1521 (1367, -0.4%), and the Intel Xeon E3-1226 v3 (1357, 0.4%). The i3-9100TE has an average score of 1386, placing it at the 37th percentile, one point ahead of the i5 in percentile ranking despite losing every head-to-head test. Its nearest rivals are the AMD Opteron 6274 (1387, -0.1%), AMD Opteron 6238 (1383, 0.3%), Intel Core i7-3615QE (1381, 0.4%), and AMD Opteron 6366 HE (1379, 0.5%). The i3's slightly higher average score likely comes from its Geekbench results, which are not available for the i5.

The Verdict

The data points to a single conclusion: the Intel Core i5-8365UE is the faster processor. It wins every recorded Cinebench test by a consistent margin of roughly 17%. That advantage holds in both single-core and multi-core workloads, which means the i5-8365UE should be preferred for any application where compute performance matters, from rendering to general productivity. Its 4 cores and 8 threads give it a structural advantage over the i3-9100TE's 4 cores and 4 threads, and its 4.10 GHz boost clock outpaces the i3's 3.20 GHz.

The i3-9100TE is not without a case. It supports ECC memory, a feature the i5 lacks, and it sits on a socketed platform that allows for motherboard replacement and easier servicing. It is also a desktop part, which may matter for systems that do not rely on mobile packaging. The i3's 35 W TDP is higher than the i5's 15 W, but that is a power budget, not a performance metric. Its launch MSRP was $122, while the i5-8365UE launched at $297.

For a buyer choosing between these two, the decision hinges on platform requirements. If the system demands ECC memory or a replaceable CPU, the i3-9100TE is the only option. If performance is the priority, the i5-8365UE is the clear winner, offering a 17% improvement across the board while drawing less power. The i5-8365UE also remains in active production, whereas the i3-9100TE is end-of-life. The percentile rankings are close, 37th for the i3 and 36th for the i5, but the head-to-head data is not. The i5-8365UE is the better buy for raw compute, and the i3-9100TE is a niche pick for ECC and socketed flexibility.
