Intel Core 3 100U vs Intel Core i7-14701E Comparison

The Verdict

The Intel Core i7-14701E is the decisive winner across every recorded benchmark, taking all 17 head-to-head tests. The data shows a processor that outclasses the Intel Core 3 100U in every measurable workload, from single-threaded tasks to heavily parallel multi-core rendering. The i7-14701E posts an average benchmark score of 33206, while the Core 3 100U manages 16148, roughly half the performance. The percentile ranking reinforces this gap: the i7-14701E sits in the 83rd percentile of all CPUs, while the Core 3 100U lands in the 70th percentile.

The Core 3 100U fits a specific niche. It is a mobile processor with a 15 W TDP, built for thin-and-light systems where battery life and thermals matter more than raw output. Its benchmark scores are respectable for its class, and it trails the i7-14701E by 52% or more in most multi-threaded tests. The i7-14701E, by contrast, is a desktop part with a 65 W TDP and 8 cores, 16 threads, which gives it a substantial structural advantage in parallel workloads.

For users prioritizing minimum power draw and a compact mobile platform, the Core 3 100U is the only choice between these two, as the i7-14701E is a desktop chip on Socket 1700. For anyone building or upgrading a desktop system and needing maximum throughput in rendering, compression, encryption, or math-heavy tasks, the i7-14701E is the clear pick. The benchmark data leaves no ambiguity: the i7-14701E wins every single test, often by margins exceeding 50%.

Architecture Differences

Both processors use the Raptor Lake architecture and are fabricated on Intel's 10 nm process node. The Core 3 100U uses the Raptor Lake-U codename, while the i7-14701E uses Raptor Lake-R, reflecting a refresh iteration. The core counts differ significantly: the Core 3 100U has 6 cores and 8 threads, while the i7-14701E has 8 cores and 16 threads. This extra pair of cores and doubled thread count is a primary source of the i7-14701E's multi-threaded advantage.

Clock speeds also separate the two. The Core 3 100U has a base clock of 1.20 GHz and a boost clock of 4.70 GHz. The i7-14701E runs at 2.60 GHz base and 5.40 GHz boost. The higher base and boost clocks contribute to the i7-14701E's lead in single-threaded tests, where it scores 3133 in Cinebench R23 single-core versus 1499 for the Core 3 100U.

Cache configurations differ as well. Both have 80 KB L1 cache per core. The L2 cache is 1.25 MB per core on the Core 3 100U, while the i7-14701E has 2 MB per core. The L3 cache is 10 MB shared on the Core 3 100U versus 33 MB shared on the i7-14701E. The larger L2 and L3 caches on the i7-14701E give it more on-die storage for frequently accessed data, which helps in workloads with repeated memory access patterns.

The i7-14701E also has a larger die at 257 mm², while the Core 3 100U's die size is not recorded. The integrated graphics differ: the Core 3 100U uses UHD Graphics 64EU, while the i7-14701E uses UHD Graphics 770. Both support DDR4 and DDR5 memory over a dual-channel bus. The i7-14701E adds ECC memory support, which the Core 3 100U lacks. PCIe connectivity also differs: the Core 3 100U provides Gen 4 with 8 lanes, while the i7-14701E provides Gen 5 with 16 lanes, offering more bandwidth and more expansion headroom on the desktop platform.

Where Each One Wins

The Core 3 100U wins in power efficiency and platform portability. Its 15 W TDP is a fraction of the i7-14701E's 65 W TDP, making it suitable for laptops and compact mobile devices. The data shows no benchmark where the Core 3 100U leads, so its advantage is strictly in power consumption and form factor, not performance.

The i7-14701E wins in every performance category recorded. Its largest margins come in find prime numbers, where it leads by 70.5%, and physics, where it leads by 63.5%. It also leads by over 57% in extended instructions, over 54% in floating point math, and over 52% in Cinebench multi-core tests. In single-threaded performance, the i7-14701E leads by 18.6% based on PassMark single-thread scores, a smaller margin but still a clear victory.

The use-case split is straightforward: mobile users who need a low-power chip for a laptop should consider the Core 3 100U. Desktop users who need maximum performance for rendering, simulation, or heavy multitasking should choose the i7-14701E. The i7-14701E also supports ECC memory, which can matter in workstation or server environments where data integrity is critical.
