Intel Core 3 100U vs Intel Core i7-10850H Comparison

The Intel Core i7-10850H and Intel Core 3 100U are both six-core mobile processors, but they target completely different ends of the laptop spectrum. The i7-10850H is a 45W part from Intel’s 10th Gen Comet Lake-H family, while the Core 3 100U is a 15W Raptor Lake-U chip released in early 2024. Despite the generational gap and power disparity, benchmark results show they land in the same performance tier overall, with the newer Core 3 winning most tests but the older i7 holding specific workload advantages.

FAQ

Q: Do both CPUs support the same memory and PCIe standards?

A: No. The i7-10850H supports DDR4 with dual-channel memory and has PCIe Gen 3 with 16 lanes. The Core 3 100U supports both DDR4 and DDR5, also dual-channel, but has PCIe Gen 4 with only 8 lanes.

Q: Which processor has more threads?

A: The i7-10850H has 12 threads from its 6 cores, while the Core 3 100U has 8 threads from its 6 cores. The Core 3 lacks Hyper-Threading on some cores, yet still wins most multi-threaded benchmark tests.

Architecture Differences

The two CPUs come from vastly different design eras. The i7-10850H uses the Comet Lake architecture on a 14 nm process node, while the Core 3 100U is built on Raptor Lake using a 10 nm node. This process shrink is a major factor in the Core 3’s ability to match or beat a higher-TDP chip at less than a third of the power draw.

Core configuration differs notably. Both have 6 physical cores, but the i7-10850H supports 12 threads, whereas the Core 3 100U only manages 8 threads. The Core 3 compensates with a newer microarchitecture that delivers higher instructions per clock. Cache layouts are also distinct: the i7 has 64 KB L1 and 256 KB L2 per core, plus 12 MB shared L3. The Core 3 uses 80 KB L1 and 1.25 MB L2 per core, but only 10 MB shared L3. The larger per-core L2 on the Core 3 helps with latency-sensitive workloads.

Memory and I/O capabilities reflect their respective generations. The i7-10850H is limited to DDR4 with a memory bandwidth of 46.9 GB/s. The Core 3 100U supports both DDR4 and DDR5, though its memory bandwidth figure is not specified. PCIe support also differs: the i7 offers 16 Gen 3 lanes, while the Core 3 provides only 8 Gen 4 lanes, which doubles per-lane bandwidth but halves lane count.

Integrated graphics are another differentiator. The i7 uses UHD Graphics, while the Core 3 features UHD Graphics 64EU, indicating a more capable iGPU with additional execution units. Both CPUs are unlocked for overclocking, and both target the mobile market segment. The Core 3 100U was released on 2024-01-07, nearly four years after the i7-10850H’s 2020-04-01 launch, and carries a launch MSRP of $426.

Head-to-Head Benchmarks

The Core 3 100U dominates the Cinebench suite across the board. In R15 multi-core, it scores 1070 versus 986 for the i7, a 7.9% margin. Single-core R15 shows the same gap: 150 versus 139, also 7.3% behind. R20 and R23 follow the identical pattern, with the Core 3 leading by 7.9% in every multi-core test and 7.8-7.9% in single-core. This consistency suggests a clear architectural advantage for the newer chip in both lightly-threaded and heavily-threaded rendering workloads.

The PassMark suite tells a more complex story. The i7-10850H wins four tests, starting with a massive 21.5% lead in data compression (165882 versus 136497). It also wins extended instructions by 31.5% (10381 versus 7894) and random string sorting by 41.8% (21537 versus 15191). Integer math is a narrow 0.9% win for the i7 (39919 versus 39580), showing near-parity on that workload.

The Core 3’s PassMark victories are equally emphatic. Data encryption is its standout win: 8128 versus 3890, a 52.1% advantage. Single-thread performance is also decisive, with 3506 versus 2668, a 23.9% lead. The Core 3 wins floating point math by 11% (28322 versus 25216), physics by 18% (876 versus 718), and find prime numbers by 21.2% (52 versus 41). Its multithread score of 12522 beats the i7’s 11643 by 7%.

Overall, the Core 3 100U wins 13 of the 17 head-to-head benchmarks, with the i7-10850H taking only 4. The average benchmark score difference is just 0.3% in favor of the i7, which highlights how the Core 3’s wins are often large but concentrated in fewer tests, while the i7’s wins are also substantial but less frequent.

Specification Differences

The two processors differ in nearly every specification category. Clock speeds show the i7-10850H with a 2.70 GHz base and 5.10 GHz boost, while the Core 3 100U runs at 1.20 GHz base and 4.70 GHz boost. The i7 has a far higher base clock, but the Core 3’s boost is only 0.4 GHz lower, demonstrating better efficiency at peak speeds.

Thermal design power is a stark contrast: the i7-10850H is rated at 45W TDP, while the Core 3 100U sips just 15W. This is a 30W difference that directly impacts laptop chassis design, cooling requirements, and battery life. Socket compatibility also differs, with the i7 using Intel BGA 1440 and the Core 3 using Intel BGA 1744.

Process node and architecture generation are the foundational differences. The i7 is 14 nm Comet Lake, while the Core 3 is 10 nm Raptor Lake. Cache sizes differ as described earlier, with the i7 having more L3 (12 MB versus 10 MB) but the Core 3 having larger L1 and L2 per core. Memory support and PCIe lanes also split the two, with the newer chip supporting DDR5 and PCIe Gen 4.

Both CPUs lack ECC memory support and have locked multipliers. Both are produced by Intel and remain in active production. The part numbers are SRH8P for the i7 and SRMYL for the Core 3. Only the Core 3 has a listed launch MSRP of $426.

Where Each One Wins

The Core 3 100U is the clear winner for productivity and general use. Its 23.9% single-thread lead in PassMark translates to snappier application loading, faster web browsing, and better responsiveness in everyday tasks. The 52.1% advantage in data encryption makes it the better choice for security-focused workloads like VPN connections or encrypted file operations. Rendering and creative work also favor the Core 3, as shown by its consistent 7.9% lead across all Cinebench versions. The 18% physics win suggests stronger performance in simulation tasks, while the 11% floating-point advantage benefits scientific computing.

The i7-10850H is the specialist for data-heavy operations. Its 41.8% win in random string sorting and 31.5% win in extended instructions indicate superior performance in database indexing, text processing, and code compilation with complex instruction sets. The 21.5% lead in data compression makes it ideal for archiving, backup, and file transfer workflows. Its 0.9% integer math win is marginal, but for workloads that rely heavily on integer operations, the i7 holds a slight edge. The i7’s higher 45W TDP also suggests it can sustain these workloads longer under continuous load, though this is not directly measured in the benchmark data.

For gaming, neither chip is a clear winner based on the provided CPU benchmarks. The Core 3’s single-thread advantage helps with frame pacing, but the i7’s larger L3 cache and more threads could benefit modern titles. The data does not include GPU benchmarks, so a definitive gaming recommendation is not possible from these numbers alone.

The Verdict

Choose the Intel Core 3 100U if you want a modern, efficient chip that wins the majority of benchmark tests. It offers superior single-thread performance, better encryption throughput, and wins every Cinebench rendering test by nearly 8%. The 15W TDP makes it viable for thin-and-light laptops with passive cooling, and its DDR5 support future-proofs memory upgrades. The 2024 release date means it has a longer software support window.

Choose the Intel Core i7-10850H if your workloads are dominated by data compression, extended instruction sets, or random string sorting. It wins these by margins of 21.5%, 31.5%, and 41.8% respectively, which are substantial enough to justify the older architecture. The 16 PCIe Gen 3 lanes also provide more flexibility for discrete GPUs in a gaming laptop. Its higher base clock of 2.70 GHz may benefit workloads that run at constant frequency rather than bursty boost clocks.

The data shows a near-total performance tie in average benchmark scores (16204 versus 16148), but the distribution of wins matters. The Core 3 is the more balanced and modern processor, winning 13 of 17 benchmarks. The i7 is a niche performer that wins 4 specific tests by large margins. For most users, the Core 3 100U is the better all-rounder. For specialized data-handling tasks, the i7-10850H remains a viable, if dated, option. The 70th percentile ranking for both CPUs against all processors confirms they are middle-of-the-pack performers in the broader CPU landscape, with neither offering a decisive advantage for most applications.
