Intel Core i5-1335UE vs Intel Core i7-9850H Comparison

The benchmark data presents a clear generational shift between the Intel Core i7-9850H and the Intel Core i5-1335UE. The newer i5-1335UE secures a decisive victory across every single head-to-head comparison, with all six tests showing a consistent performance advantage over the older i7-9850H. The average benchmark scores are nearly identical—2934 for the i7-9850H versus 2907 for the i5-1335UE—yet the specific Cinebench results reveal a nuanced story where the efficiency-oriented i5 consistently outpaces the higher-TDP i7.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the uniformity of the i5-1335UE's wins. In Cinebench R15 multicore, the i5-1335UE scores 1013 against the i7-9850H's 925, a delta of -8.7% from the perspective of the i7. This translates to the i5 being roughly 9.5% ahead. The single-core R15 test shows a similar gap: 142 for the i5 versus 130 for the i7, an 8.5% delta. These margins are not anomalies; they repeat across every workload.

Moving to Cinebench R20, the i5-1335UE again takes the lead with a multicore score of 4221 compared to 3856 for the i7-9850H, an 8.6% difference. The single-core R20 results follow suit, with 595 versus 544, also an 8.6% delta. The consistency of these numbers suggests a fundamental architectural advantage rather than a workload-specific quirk. The i5-1335UE is not just slightly faster; it is uniformly faster by a margin that holds steady around 8.5-8.7% across all four Cinebench R15 and R20 tests.

The longest rendering workload, Cinebench R23, confirms the trend. The i5-1335UE posts a multicore score of 10052, crossing the five-figure threshold, while the i7-9850H manages 9182—an 8.7% delta. In single-core R23, the i5 scores 1419 against 1296, again an 8.7% gap. Notably, the i5-1335UE achieves these wins despite having a significantly lower base clock of 1300 MHz compared to 2600 MHz for the i7-9850H, and a boost clock that is slightly lower at 4.50 GHz versus 4.60 GHz. The data shows the i5's efficiency cores and newer microarchitecture more than compensate for the raw clock speed deficit.

For the i7-9850H, the outlook is grim. It wins zero benchmarks in this head-to-head set. Its best relative performance comes in the single-core tests where the delta is slightly smaller (-8.5% in R15 single), but it still loses. The i7's average benchmark score of 2934 places it at the 51st percentile of all CPUs, with nearest rivals including the Intel Core i5-9600KF at 2935 (0% delta) and the AMD Ryzen Embedded V3C14 at 2921 (0.5% delta). The i5-1335UE, with an average score of 2907, sits at the same 51st percentile, with its closest competitor being the AMD Ryzen 5 PRO 1600 at 2909 (-0.1% delta). Both chips occupy a similar overall performance tier, but the head-to-head data shows the i5-1335UE is the clear winner within that tier.

The Verdict

From a pure performance standpoint, the Intel Core i5-1335UE is the superior processor in this comparison. It wins every single benchmark test, with margins ranging from 8.5% to 8.7%. There is no workload category in the provided data where the i7-9850H manages to close the gap or take a lead. If the decision is based solely on the Cinebench suite of tests, the i5-1335UE is the unequivocal choice.

The i7-9850H, despite its higher TDP of 45 watts versus 15 watts for the i5, cannot translate that additional power budget into performance. The i5-1335UE achieves its wins while consuming one-third the thermal envelope, according to the TDP figures. This suggests that for mobile systems where thermals and battery life are priorities, the i5-1335UE offers a compelling combination of superior performance and lower power draw. The i7-9850H, being end-of-life with a 2019 release date, represents older technology that has been surpassed by the newer Raptor Lake architecture.

Users who already own systems with the i7-9850H should not feel the need to upgrade based on these numbers alone, as the performance delta is noticeable but not transformative. However, for anyone selecting a new mobile workstation or laptop, the data clearly points to the i5-1335UE as the better performer. The i7-9850H's only potential advantage would be in scenarios not covered by the benchmark data, such as specific software optimizations or legacy compatibility, but within the scope of this analysis, the i5-1335UE is the winner.

Architecture Differences

The architectural divide between these two processors is substantial, reflecting a five-generation leap in Intel's design philosophy. The i7-9850H is built on the Coffee Lake architecture, specifically the Coffee Lake-HR codename, using a 14 nm process node manufactured by Intel. It features a monolithic design with 6 cores and 12 threads, all based on the same performance-oriented core type. The die size is listed at 149 mm², providing a physical footprint for the older design.

In contrast, the i5-1335UE is based on Raptor Lake, with the codename Raptor Lake-U, built on a 10 nm process node, also from Intel's foundry. This is a hybrid architecture, featuring 10 cores and 12 threads, which implies a mix of performance and efficiency cores. The L1 cache is 80 KB per core, larger than the 64 KB per core on the i7-9850H, and the L2 cache is significantly larger at 1.25 MB per core versus 256 KB per core. Both share the same 12 MB of shared L3 cache, but the Raptor Lake design allocates resources differently across its hybrid core layout.

The process node shrink from 14 nm to 10 nm is a critical factor in the performance-per-watt improvements. The i5-1335UE's base clock of 1300 MHz is substantially lower than the i7-9850H's 2600 MHz, which is likely due to the efficiency cores running at lower frequencies to conserve power. The boost clock is nearly identical, with the i7 at 4.60 GHz and the i5 at 4.50 GHz, indicating that the newer chip can reach similar peak frequencies despite the lower base. The integrated graphics also differ, with the i7 featuring UHD Graphics 630 and the i5 featuring Iris Xe Graphics 80EU, a newer and more capable GPU solution.

Specification Differences

The specification sheets reveal several key differences beyond the core count and clock speeds. The i7-9850H has a TDP of 45 watts, while the i5-1335UE is rated at just 15 watts. This threefold difference in power consumption is the most striking specification gap. The socket types are incompatible: the i7 uses Intel BGA 1440, while the i5 uses Intel BGA 1744, meaning they are not interchangeable in the same motherboard.

Memory support differs as well. The i7-9850H supports DDR4 memory only, with a dual-channel bus and a listed memory bandwidth of 42.7 GB/s. The i5-1335UE supports both DDR4 and DDR5 memory, also on a dual-channel bus, though no specific bandwidth figure is provided. The PCIe interface also advances: the i7 supports PCIe Gen 3, while the i5 supports PCIe Gen 4 with 8 lanes on the CPU. The i5's die size is not listed, whereas the i7's is 149 mm². Finally, the i7-9850H is marked as end-of-life with a release date of April 2019, while the i5-1335UE is active and was released in January 2023.

Where Each One Wins

The Intel Core i5-1335UE wins every benchmark in the provided dataset. Its victories span all six Cinebench tests, covering both single-core and multicore workloads across R15, R20, and R23 versions. The margins are consistent, ranging from 8.5% to 8.7%, indicating a broad performance advantage that holds across different rendering and compute tasks. This makes it the clear choice for applications that rely on CPU rendering, such as video encoding, 3D modeling, and software compilation, where the higher multicore scores of 1013, 4221, and 10052 would be beneficial.

The Intel Core i7-9850H has no benchmark wins in this comparison. Its only potential advantage lies in its higher boost clock of 4.60 GHz, though this does not translate into a win in any single-core test. The i7's higher TDP of 45 watts suggests it might sustain peak performance for longer periods under heavy load in a system designed to dissipate that heat, but the data does not support this as a real-world advantage. For users with legacy software that requires the specific Coffee Lake architecture or older instruction sets, the i7 could be a fallback, but the benchmark results show no scenario where it outperforms the i5-1335UE. In every measurable way, the i5-1335UE is the superior processor for modern workloads.
