Intel Core i5-9600 vs Intel Core i7-9850HE Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core i7-9850HE across all six Cinebench comparisons. The mobile part wins every single benchmark, though the margins are consistently narrow. In the R15 multicore test, the i7-9850HE scores 843 against the i5-9600's 820, a 2.8% advantage. The single-core R15 result is slightly more pronounced: 119 versus 115, a 3.5% lead. That 3.5% margin is the largest delta recorded in the entire head-to-head set.

Moving to R20, the pattern holds. The i7-9850HE posts 3515 in multicore, while the i5-9600 manages 3419, again a 2.8% difference. Single-core R20 sees the i7-9850HE at 496 and the i5-9600 at 482, a 2.9% gap. The R23 results mirror the earlier tests almost exactly: multicore 8370 versus 8141 and single-core 1181 versus 1149, both representing a 2.8% edge for the i7-9850HE.

The consistency of these deltas is notable. Across six benchmarks, five of them land at either 2.8% or 2.9%, with one outlier at 3.5%. This uniformity suggests the i7-9850HE's advantage is structural rather than workload-specific. It is not that the mobile chip wins big in one area and loses elsewhere; it wins by the same small margin everywhere. The average benchmark score in the database reflects this: the i7-9850HE sits at 2421, while the i5-9600 averages 2354, a gap of roughly 67 points or about 2.8%.

Both processors occupy the same 48th percentile among all CPUs in the database. That means neither chip is an outlier in the broader market; they are both mid-pack performers. The head-to-head data, however, shows that within that mid-pack tier, the i7-9850HE is consistently the stronger of the two.

Where Each One Wins

The i7-9850HE wins all six recorded benchmark tests, so there is no test category where the i5-9600 takes the lead. That said, the strength of the i7-9850HE varies by workload type. The largest relative advantage appears in single-threaded R15, where the 3.5% delta suggests the mobile chip's higher per-core efficiency shines in lightly threaded scenarios. The single-core R20 and R23 tests show a slightly smaller 2.8% to 2.9% edge, but the direction is identical.

For multi-threaded workloads, the i7-9850HE also wins, but the margin is uniform at 2.8% across R15, R20, and R23. This consistency points to a simple explanation: the i7-9850HE has 12 threads to the i5-9600's 6, and the extra thread count translates into a steady multi-core advantage. The fact that the delta does not grow in longer or more demanding workloads suggests the i7-9850HE is not throttling under sustained load, at least not in the recorded data.

The i5-9600's best showing relative to its rival is in the multicore tests, where it trails by the same 2.8% as everywhere else. Its single-core results are actually closer to the i7-9850HE in R20 and R23 than in R15, but it never closes the gap. In terms of use cases, the i7-9850HE is the pick for both single-threaded responsiveness and multi-threaded rendering. The i5-9600 remains competitive, but the data does not identify a single category where it comes out ahead.

Architecture Differences

Both processors are built on Intel's 14 nm process and share the Coffee Lake architecture. The i7-9850HE uses the Coffee Lake-HR codename, while the i5-9600 uses the plain Coffee Lake codename from the Coffee Lake Refresh generation. Both have 6 physical cores and identical cache hierarchies: 64 KB of L1 per core, 256 KB of L2 per core, and 9 MB of shared L3. The process node, foundry, and core count are therefore identical.

The critical difference is threading. The i7-9850HE supports 12 threads, meaning each core handles two threads simultaneously. The i5-9600 supports only 6 threads, one per core. This explains the consistent multi-core benchmark advantage for the i7-9850HE. The mobile chip also has a lower base clock at 2.70 GHz versus the i5-9600's 3.10 GHz, but a slightly lower boost clock of 4.40 GHz against 4.50 GHz. Despite the lower clocks on paper, the i7-9850HE still wins every benchmark, which suggests the extra threads and possibly other architectural tweaks compensate for the raw clock deficit.

The TDP figures differ substantially: the i7-9850HE is rated at 45 watts, while the i5-9600 is rated at 65 watts. The mobile chip achieves its benchmark wins at a lower thermal envelope, which is unusual given the desktop part's higher power allowance. The sockets are also different: the i7-9850HE uses Intel BGA 1440, a soldered mobile platform, while the i5-9600 uses Intel Socket 1151, a desktop socket. The i7-9850HE has a die size of 149 mm², while the i5-9600's die size is not recorded in the database.

Both support DDR4 memory over a dual-channel bus with identical 42.7 GB/s bandwidth. Neither supports ECC memory. Both integrate graphics, though the naming differs slightly: the i7-9850HE lists UHD Graphics 630, while the i5-9600 lists UHD 630. The PCIe support is Gen 3 for both, but the i5-9600 specifies 16 lanes from the CPU, while the i7-9850HE simply lists Gen 3 without a lane count. The i7-9850HE is a mobile part, and the i5-9600 is a desktop part. Both are end-of-life and neither has an unlocked multiplier.

The Verdict

The data points clearly to the Intel Core i7-9850HE as the superior performer in this pairing. It wins every single benchmark in the database, and its advantages are consistent across both single-threaded and multi-threaded workloads. For users who prioritize raw benchmark scores, the i7-9850HE is the unambiguous choice. The 12-thread configuration gives it a structural edge in multi-threaded tasks, while its single-core results show it can also hold its own in lightly threaded applications.

That said, the i5-9600 is not far behind. The largest single delta is 3.5%, and most margins sit at 2.8%. In real-world terms, this is a modest gap. The i5-9600 does have higher base and boost clocks, which might appeal in scenarios where clock speed matters more than thread count, but the recorded benchmarks do not show any test where that translates into a win.

The platform differences matter for purchasing decisions. The i7-9850HE is a mobile part on the BGA 1440 socket, which means it is soldered and not upgradeable in a standard desktop. The i5-9600 uses Socket 1151, which offers more flexibility for desktop builds. The i7-9850HE also operates at a lower TDP, which could be an advantage in thermally constrained systems, but the i5-9600's higher TDP is typical for desktop parts.

For a workstation or laptop replacement where benchmark performance is the priority, the i7-9850HE is the better choice. For a desktop build where socket compatibility and upgradeability are factors, the i5-9600 remains a viable option, but the data shows it is slightly slower in every measured test. Both chips sit at the 48th percentile among all CPUs, so neither is a top-tier performer, but within this comparison, the i7-9850HE is the winner.

The two processors share the same 6-core layout, 14 nm process, cache configuration, memory support, and 42.7 GB/s memory bandwidth. They differ most significantly in thread count, TDP, socket, and clock speeds. The i7-9850HE trades lower clocks and a mobile socket for double the thread count and a lower power draw, while the i5-9600 offers higher clocks and a desktop socket but fewer threads and a higher TDP.
