Intel Core i3-8350K vs Intel Core i5-10200H Comparison

The Intel Core i5-10200H and the Intel Core i3-8350K occupy two very different corners of the same family tree. One is a modern mobile part from the Comet Lake-H line, a 45-watt processor designed for laptops; the other is an end-of-life Coffee Lake desktop chip built on Socket 1151 with an unlocked multiplier and a much higher power budget. The recorded benchmark data shows a remarkably consistent picture across rendering tests, with one significant reversal in Geekbench. Across the eight head-to-head measurements in the database, the i5-10200H wins six and the i3-8350K wins two, yet the two chips sit nearly side by side in the overall rankings: the i5-10200H holds the 47th percentile against all CPUs with an average score of 2154, while the i3-8350K sits at the 46th percentile with an average score of 2096.

Head-to-Head Benchmarks

The Cinebench suite is a clean sweep for the i5-10200H, and the margins are almost identical in every single test. In Cinebench R15 multi-core the mobile chip scores 684 against 593, a lead of 15.3 percent. Single-core R15 goes the same way: 96 to 83, a 15.7 percent advantage. Cinebench R20 multi-core reads 2853 versus 2471 and single-core 402 versus 348, both 15.5 percent in favor of the i5-10200H. Cinebench R23 repeats the pattern exactly: 6795 against 5884 in multi-core and 959 against 830 in single-core, again a 15.5 percent gap.

That consistency is itself informative. A uniform 15 to 16 percent lead across three Cinebench generations, in both single-threaded and multi-threaded runs, points to a structural per-core advantage for the Comet Lake-H part rather than a workload-specific quirk. Sustained throughput scales with it, and the four extra threads of the i5-10200H do not distort the picture: even the single-core results, which are immune to thread count, favor the mobile chip by the same margin.

Geekbench flips the result entirely. The i3-8350K wins Geekbench multi-core 4992 to 4096, ahead by 17.9 percent, and Geekbench single-core 1564 to 1347, ahead by 13.9 percent. This is the one domain where the desktop part clearly dominates, and the reversal is large enough to matter. The database indicates that workloads resembling Geekbench, which leans on bursty real-world application traces, play to the i3-8350K's strengths, while sustained rendering workloads favor the i5-10200H.

Context from the rivals list sharpens the picture. The i5-10200H's average score of 2154 places it essentially level with the Intel Core i7-5950HQ at 2158, marginally ahead of the AMD Ryzen 3 3300X at 2148, just behind the Intel Core i5-7640X at 2167, and ahead of the Intel Core i5-9400T at 2136. The i3-8350K's average of 2096 puts it in a cluster with the AMD Ryzen 7 1700X at 2094, the AMD Ryzen 5 PRO 2400G at 2101, the AMD Ryzen Embedded R2544 at 2086, and the Intel Core i5-8259U at 2108. Both chips compete in the same crowded mid-tier neighborhood, separated by only 58 points on average, but they get there through opposite strengths.

Architecture Differences

Both processors come from Intel on the 14 nm process node, so there is no lithographic advantage on either side. The architectural distinction is generational and segment-based. The i5-10200H is a Comet Lake design, codenamed Comet Lake-H, a mobile part soldered to Intel BGA 1440 and still listed as Active in production. The i3-8350K is a Coffee Lake design on Socket 1151, a desktop socket that allows replacement and upgrades, but the chip is End-of-life.

The core topology differs in one crucial way: both have four physical cores, but the i5-10200H supports Hyper-Threading and runs eight threads, while the i3-8350K runs four threads on four cores. Clock behavior is inverted. The desktop chip has the higher fixed frequency, a 4.00 GHz base clock with no boost clock listed, reflecting its 91-watt TDP budget. The mobile chip starts at a 2.40 GHz base but boosts to 4.10 GHz under its 45-watt TDP, which helps explain its single-core wins in Cinebench despite the lower baseline.

Cache goes the other way. The i3-8350K carries 8 MB of shared L3 cache against 6 MB on the i5-10200H; both share identical L1 (64 KB per core) and L2 (256 KB per core) configurations. Memory support also differs. The i5-10200H accepts DDR3 and DDR4 on a dual-channel bus with 46.9 GB/s of bandwidth, while the i3-8350K is DDR4-only, dual-channel, at 38.4 GB/s. Notably, the desktop chip supports ECC memory and the mobile chip does not, an unusual distinction for a consumer desktop part.

Feature trade-offs continue down the spec sheet. The i3-8350K has an unlocked multiplier, making it the only one of the two that can be overclocked, and its die size is recorded at 126 mm². The i5-10200H's multiplier is locked, consistent with its mobile BGA packaging. Both offer PCIe Gen 3, with the desktop part specified at 16 lanes from the CPU. Integrated graphics differ in generation naming: UHD Graphics on the i5-10200H versus UHD Graphics 630 on the i3-8350K.

FAQ

Q: Which CPU is faster in Cinebench rendering?

A: The Core i5-10200H wins every Cinebench test in the database. It leads by 15.3 percent in R15 multi-core, 15.7 percent in R15 single-core, and 15.5 percent across all four R20 and R23 tests.

Q: Does the Core i3-8350K ever win?

A: Yes. It takes both Geekbench tests: multi-core by 17.9 percent (4992 versus 4096) and single-core by 13.9 percent (1564 versus 1347). These are its only two wins in eight head-to-head measurements.

Q: Which chip has more threads?

A: The i5-10200H has eight threads across four cores thanks to Hyper-Threading. The i3-8350K has four cores and four threads.

Q: Can either processor be overclocked?

A: Only the i3-8350K, which has an unlocked multiplier. The i5-10200H's multiplier is locked.

Q: How do they compare against other CPUs in the database?

A: They are nearly equivalent overall. The i5-10200H sits in the 47th percentile with an average score of 2154, close to the Ryzen 3 3300X and Core i5-7640X. The i3-8350K is in the 46th percentile at 2096, alongside the Ryzen 7 1700X and Ryzen 5 PRO 2400G.

Q: Do they support ECC memory?

A: The i3-8350K supports ECC. The i5-10200H does not.

The Verdict

The data supports a workload-driven recommendation. For sustained rendering and content creation, the Core i5-10200H is the stronger choice: six wins from eight tests, a uniform 15 percent advantage across the entire Cinebench family in both single-core and multi-core modes, double the thread count, and higher memory bandwidth at 46.9 GB/s versus 38.4 GB/s. It is also the only one of the two still in active production.

The Core i3-8350K argues for itself where burst-oriented application performance dominates. Its 17.9 percent Geekbench multi-core win and 13.9 percent single-core win are the largest margins recorded in this matchup, and its 4.00 GHz base clock, 8 MB of L3 cache, 91-watt TDP, unlocked multiplier, and socketed Socket 1151 packaging give it headroom the mobile part cannot match. ECC support further distinguishes it for stability-sensitive desktop builds.

Overall the two are statistical peers, separated by one percentile point and 58 points of average score, but they reach parity by opposite routes. Buyers prioritizing rendering throughput and platform longevity should lean i5-10200H; those prioritizing burst performance, overclocking, and a socketed desktop platform should lean i3-8350K.
