Intel Core i7-1365UE vs Intel Core i7-8850H Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core i7-1365UE wins every single head-to-head test against the Intel Core i7-8850H, taking all six recorded comparisons. The older Coffee Lake-H part does not post a single victory, so for any workload captured in the database, the Raptor Lake-U processor is the stronger choice. The i7-1365UE leads by roughly 8.7 to 9.2 percent in Cinebench tests, which is a consistent margin across single-core and multi-core workloads alike.

The i7-8850H still occupies a relevant place in the database. Its average benchmark score of 2604 places it in the 49th percentile, and its nearest rivals include the AMD Ryzen 3 PRO 4355GE and the Intel Xeon E-2174G, both within 0.6 percent. The i7-1365UE sits slightly higher at the 50th percentile with an average score of 2677, placing it marginally ahead of the Intel Core i5-9500F and Intel Core i7-9700T. The practical takeaway is that the newer 15 W part outperforms the older 45 W part across the board, despite the latter having a much higher thermal envelope. Users who need maximum single-thread responsiveness or sustained multi-core rendering in the recorded tests should choose the i7-1365UE.

Architecture Differences

The two processors come from different eras of Intel mobile silicon. The i7-1365UE uses Raptor Lake architecture on a 10 nm process, while the i7-8850H uses Coffee Lake on a 14 nm process. The die size for the i7-8850H is recorded at 149 mm², while the i7-1365UE has no die size listed. The newer chip also has a different socket, Intel BGA 1744, compared to the i7-8850H's Intel BGA 1440.

Core counts differ significantly. The i7-1365UE has 10 cores and 12 threads, while the i7-8850H has 6 cores and 12 threads. Both parts offer the same thread count, but the i7-1365UE accomplishes this with more physical cores, which suggests a hybrid or efficiency-oriented design. The cache layouts diverge as well. The i7-1365UE has 80 KB of L1 per core and 1.25 MB of L2 per core, while the i7-8850H has 64 KB of L1 per core and 256 KB of L2 per core. Both share 12 MB of L3, so the total last-level cache is identical, but the per-core L2 allocation is much larger on the newer part.

Memory support also differs. The i7-1365UE supports DDR4 and DDR5 in a dual-channel configuration, while the i7-8850H supports DDR4 only. The integrated graphics differ as well: the i7-1365UE carries Iris Xe Graphics with 80 execution units, while the i7-8850H uses the older UHD 630. The i7-1365UE also supports PCIe Gen 4 with 8 CPU lanes, while the i7-8850H has no PCIe information recorded. The production status tells a clear story: the i7-1365UE is Active, while the i7-8850H is End-of-life.

Where Each One Wins

The i7-1365UE wins everywhere in the recorded data, but the nature of its victories matters. In single-core tests, the delta is slightly larger. The i7-1365UE leads by 9.2 percent in Cinebench R15 single-core and 8.7 percent in both R20 and R23 single-core. This indicates that the newer architecture's higher boost clock of 4.90 GHz, compared to 4.30 GHz on the i7-8850H, translates into a meaningful advantage for lightly threaded tasks.

In multi-core tests, the i7-1365UE maintains an 8.8 percent lead across R15, R20, and R23. The i7-1365UE's advantage here is notable because it achieves this with a 15 W TDP against the i7-8850H's 45 W TDP. The 10-core design with a lower base clock of 1.70 GHz still outperforms the 6-core part with a 2.70 GHz base clock, which shows the efficiency gains from the newer process node and architecture.

The i7-8850H does not win any benchmark in the head-to-head set. However, its average benchmark score of 2604 and 49th percentile ranking mean it is not far behind similar-era parts. It remains competitive with chips like the Intel Xeon E-2174G and the AMD Ryzen 3 PRO 4355GE, both within 0.6 percent. For users constrained to the older platform, the i7-8850H is still a serviceable mobile processor, but it cannot match the i7-1365UE in any recorded metric.

Head-to-Head Benchmarks

The head-to-head results are consistent across all six Cinebench tests. In Cinebench R15 multi-core, the i7-1365UE scores 932 against the i7-8850H's 857, an 8.8 percent advantage. In R15 single-core, the margin widens to 9.2 percent, with scores of 131 and 120 respectively. The R20 tests show the same pattern: multi-core scores are 3887 for the i7-1365UE and 3574 for the i7-8850H, an 8.8 percent lead, while single-core scores are 548 and 504, an 8.7 percent gap.

Cinebench R23 repeats the trend. The i7-1365UE posts 9257 in multi-core against 8511 for the i7-8850H, another 8.8 percent margin. In single-core, the newer chip scores 1306 versus 1201, an 8.7 percent lead. The consistency of these deltas is striking: every multi-core test shows exactly 8.8 percent, and every single-core test sits between 8.7 and 9.2 percent. This uniformity suggests the i7-1365UE's advantage is architectural rather than workload-specific.

The i7-8850H has additional Geekbench results in the database, scoring 4765 in multi-core and 1300 in single-core. The i7-1365UE does not have Geekbench results recorded, so a direct comparison in that test is not possible. Still, across the six Cinebench tests that both processors share, the i7-1365UE wins all of them, and the database records 6 wins for the i7-1365UE and 0 for the i7-8850H.

The average benchmark scores reinforce the head-to-head picture. The i7-1365UE averages 2677, placing it in the 50th percentile of all CPUs, while the i7-8850H averages 2604, sitting at the 49th percentile. The nearest rivals for the i7-1365UE include the Intel Core i5-9500F at 2670 and the Intel Core i7-9700T at 2668, both within 0.4 percent. The i7-8850H's nearest rivals include the AMD Ryzen 3 PRO 4355GE at 2596 and the Intel Xeon E-2174G at 2588, both within 0.6 percent, with the Intel Xeon W-2125 slightly ahead at 2623.

Specification Differences

The two processors differ in nearly every major specification category. The i7-1365UE uses Raptor Lake architecture on a 10 nm process, while the i7-8850H uses Coffee Lake on a 14 nm process. The core counts are 10 versus 6, with the same 12 threads each. The base clock is 1.70 GHz for the i7-1365UE and 2.70 GHz for the i7-8850H, while the boost clock is 4.90 GHz and 4.30 GHz respectively.

TDP is a major differentiator: 15 W for the i7-1365UE versus 45 W for the i7-8850H. The sockets differ as well, with Intel BGA 1744 on the newer part and Intel BGA 1440 on the older one. L1 cache is 80 KB per core versus 64 KB per core, and L2 cache is 1.25 MB per core versus 256 KB per core. Both share 12 MB of L3.

Memory support differs, with the i7-1365UE accepting DDR4 and DDR5 in dual-channel mode while the i7-8850H is limited to DDR4. The integrated graphics are Iris Xe Graphics with 80EU on the i7-1365UE versus UHD 630 on the i7-8850H. The i7-1365UE supports PCIe Gen 4 with 8 CPU lanes; the i7-8850H has no PCIe information in the database. Production status is Active for the i7-1365UE and End-of-life for the i7-8850H. The i7-8850H has a part number, SR3YZ, and a die size of 149 mm², while the i7-1365UE lists neither. Neither processor supports ECC memory, and both are locked with no unlocked multiplier.
