AMD Ryzen 7 3700U vs Intel Celeron N5105 Comparison

Head-to-Head Benchmarks

The recorded benchmark data presents a clear picture: the AMD Ryzen 7 3700U wins all four head-to-head comparisons against the Intel Celeron N5105, and the margins are substantial. The largest gap appears in Geekbench multicore, where the Ryzen 7 3700U scores 2377 against the Celeron's 1189, a delta of 99.9%. That is effectively double the performance, a decisive outcome for any workload that can use multiple cores.

The Cinebench R15 multicore test tells a similar story, though with a slightly smaller margin. The Ryzen 7 3700U posts 672 points, while the Celeron N5105 manages 341, a delta of 97.1%. Again, the AMD part nearly doubles the Intel chip in this threaded rendering workload. These two multicore results are consistent with each other, reinforcing the idea that the Ryzen's advantage is not test-specific but reflects a fundamental throughput gap.

Single-core results narrow the gap considerably, but the Ryzen 7 3700U still leads. In Cinebench R15 single-core, the AMD chip scores 139 versus 108.1 for the Celeron, a delta of 28.6%. Geekbench single-core shows a similar relative margin: 682 for the Ryzen versus 516 for the Celeron, a delta of 32.2%. These are meaningful advantages, though nowhere near the near-doubling seen in multicore tests. The pattern suggests that the Ryzen 7 3700U's advantage grows when more threads are involved, which aligns with its 8 threads versus the Celeron's 4.

It is worth remembering the Celeron N5105 has additional benchmark entries in the database that the Ryzen 7 3700U lacks, specifically Cinebench R20 and R23 results. However, for the direct head-to-head comparison, only the four shared tests matter, and the AMD part wins all of them. The Celeron's R23 multicore score of 3388 and single-core score of 478 cannot be compared directly, since the Ryzen has no corresponding data in the pack, but they do provide context for where the Celeron sits in newer test suites.

The average benchmark scores also reflect the hierarchy. The Ryzen 7 3700U has an average score of 968, placing it at the 26th percentile among all CPUs. The Celeron N5105 averages 955, at the 25th percentile. The difference in averages is small, only 13 points, but the percentile ranking is nearly identical. This is curious: the head-to-head deltas are enormous, yet the aggregate scores are close. The explanation lies in the test sets. The Celeron's average includes its R20 and R23 results, which are competitive in their own right, whereas the Ryzen's average is drawn from a smaller set of older tests. The database treats them as near-peers overall, even though the shared benchmarks show a lopsided rivalry.

Looking at the nearest rivals in the database further contextualizes each chip. The Ryzen 7 3700U's closest match is the Intel Core i5-2400S at 968 points, a 0% delta, followed by the Intel Xeon X5570 at 967 (+0.1%) and the Intel Celeron N5100 at 966 (+0.2%). The Celeron N5105's nearest rivals include the Intel Xeon W3570 at 955 (0%), the Intel Xeon W3550 at 956 (-0.1%), and the AMD Athlon X4 870K at 956 (-0.1%). The two processors are separated by only 13 average points, yet their direct confrontation is a blowout. This is the central puzzle of this comparison, and it drives the rest of the analysis.

Where Each One Wins

The data shows that the AMD Ryzen 7 3700U wins every shared benchmark, so there is no category in which the Intel Celeron N5105 comes out ahead in the head-to-head tests. However, the use-case split is not as simple as "AMD wins everything." The Ryzen 7 3700U's wins are concentrated in multi-threaded performance, where its 8 threads provide a structural advantage. The 99.9% delta in Geekbench multicore and the 97.1% delta in Cinebench R15 multicore are the standout results. For rendering, video encoding, compilation, or any workload that scales across cores, the Ryzen 7 3700U is the clear choice.

The single-core wins are smaller but still decisive. A 28.6% lead in Cinebench R15 single-core and a 32.2% lead in Geekbench single-core mean the Ryzen 7 3700U also handles everyday responsive tasks, such as web browsing, document editing, and light application launches, with more headroom. The Celeron N5105 is not without merit in the broader database. Its Cinebench R23 multicore score of 3388 and single-core score of 478, along with an R20 multicore score of 1422 and single-core score of 200, show that it is a capable low-power part for its segment. But in the direct comparison, there is no benchmark where the Celeron takes the win.

The database percentile rankings suggest both chips sit near the low end of the overall CPU distribution, at 26% and 25% respectively. That means neither is a high-performance part by modern standards. The Ryzen 7 3700U is the stronger of the two, but both are positioned for entry-level or efficiency-focused systems. The Celeron's 10 W TDP, lower than the Ryzen's 15 W, hints at its intended role: fanless or passively cooled devices where absolute performance is secondary to power draw. The Ryzen 7 3700U, with its higher power envelope and 8 threads, targets thin-and-light laptops that need more compute capability.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 3700U is built on the Zen+ architecture, codenamed Picasso, and fabricated on a 12 nm process at GlobalFoundries. It belongs to the 3000 series and the Ryzen 7 generation. The Intel Celeron N5105 uses the Tremont architecture, codenamed Jasper Lake, on Intel's 10 nm process. The process node difference, 12 nm versus 10 nm, does not automatically determine performance, but it does reflect the era and design goals of each chip.

Core counts are identical at 4, but threading differs. The Ryzen 7 3700U supports 8 threads, meaning each core can handle two threads simultaneously. The Celeron N5105 has 4 threads, one per core. This explains the massive multicore deltas: the Ryzen can keep more work in flight per core, and the benchmark results bear this out. Cache hierarchies also diverge. The Ryzen 7 3700U has 96 KB of L1 per core and 512 KB of L2 per core, plus 4 MB of shared L3. The Celeron N5105 has 64 KB of L1 per core and a shared 1.5 MB L2, plus 4 MB of shared L3. The Ryzen's larger per-core L2 and L1 caches give it more local data capacity, which can reduce memory stalls in single-threaded workloads.

The integrated graphics differ as well. The Ryzen 7 3700U pairs with Radeon Vega 10, a 10-core GPU design. The Celeron N5105 uses Intel UHD Graphics 24EU. The database does not provide graphics benchmarks, so the practical impact of this difference is not quantified here, but the hardware specifications clearly favor the AMD solution in terms of execution units. Memory support also differs: both support DDR4 in dual-channel mode, but the Celeron adds LPDDR4 support and lists a memory bandwidth of 46.9 GB/s. The Ryzen's memory bandwidth is not listed in the database.

The Ryzen 7 3700U has a larger die at 210 mm² and 4,940 million transistors, while the Celeron N5105 is much smaller at 63.8 mm² with no transistor count listed. The die size difference reflects the integrated Vega graphics and the older 12 nm process. The Celeron's compact die on 10 nm is typical for a low-power, efficiency-first part. Production status also differs: the Ryzen 7 3700U is listed as Active, while the Celeron N5105 is End-of-life. Release dates are only provided for the Ryzen, which launched on January 5, 2019.

The Verdict

The data points to a single conclusion: the AMD Ryzen 7 3700U is the faster processor in every shared benchmark, and often by a wide margin. Its multicore wins of 97.1% and 99.9% in Cinebench R15 and Geekbench make it the obvious pick for threaded workloads, and its single-core leads of 28.6% and 32.2% ensure it also feels snappier in general use. Buyers who need compute throughput, whether for content creation, light rendering, or multitasking, should choose the Ryzen 7 3700U without hesitation.

The Intel Celeron N5105 is not without a case, but that case rests on factors outside the benchmark data. Its 10 W TDP is lower than the Ryzen's 15 W, which can matter in fanless designs or battery-conscious devices. Its support for LPDDR4 and its listed 46.9 GB/s memory bandwidth suggest an efficiency-oriented platform. The Celeron's R20 and R23 scores, while not comparable to the Ryzen in a head-to-head, show it can handle light tasks in newer test suites. However, the database's average scores place the two chips within 13 points of each other, which might tempt a buyer to treat them as equals. The head-to-head results contradict that: the Ryzen is categorically stronger where data exists.

The production status difference is also relevant. The Ryzen 7 3700U is Active, while the Celeron N5105 is End-of-life. For anyone building or buying a system today, the Ryzen offers a more future-proof path. The Ryzen's larger die, higher transistor count, and 12 nm process may seem dated next to the Celeron's 10 nm design, but those specifications do not translate into better performance in the recorded tests. The Ryzen's Zen+ architecture, 8 threads, and higher clocks dominate.

For a user prioritizing raw performance in a mobile form factor, the Ryzen 7 3700U is the only choice supported by the measurements. For a user prioritizing minimal power draw and a compact die, the Celeron N5105 has its place, but the benchmark data does not favor it in any direct comparison. The verdict, strictly from the data, is that the Ryzen 7 3700U wins this matchup decisively, and the Celeron N5105's only advantages lie in efficiency metrics and a lower TDP, not in performance scores.
