AMD Ryzen 5 7235HS vs Intel Core 3 100U Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two mobile processors. The Intel Core 3 100U takes 12 of the 17 recorded tests, while the AMD Ryzen 5 7235HS wins five. The margin of victory tells the real story: Intel's wins are often decisive, but AMD's are concentrated in specific workload types.

Starting with the Cinebench suite, Intel leads across the board, though the margins are narrow. In Cinebench R15 multicore, Intel scores 1070 against AMD's 1050, a 1.9% advantage. Single-core R15 shows 150 versus 148, a 1.4% edge. The R20 tests follow the same pattern: multicore 4462 against 4375 (2% ahead), single-core 629 against 617 (1.9% ahead). R23 multicore sees Intel at 10624 versus 10418, again 2% ahead, and single-core R23 is 1499 versus 1470, a 2% lead. These are consistent, but small, wins. The data indicates that in pure CPU rendering workloads, the Intel part holds a slim but repeatable edge.

The PassMark suite reveals where each chip has its strengths. Intel dominates in three specific tests. The most dramatic gap is in find prime numbers: Intel scores 52 versus AMD's 31, a 67.7% advantage. That is a massive lead in this particular integer workload. Physics tests also favor Intel heavily: 876 versus 574, a 52.6% margin. Floating point math shows Intel at 28322 against AMD's 23091, a 22.7% win. Single-thread performance is another Intel stronghold, with 3506 versus 2873, a 22% advantage. PassMark multithread also goes to Intel, 12522 versus 12243, a 2.3% edge.

AMD's victories are no less significant in their respective domains. The largest win for AMD comes in extended instructions: 10887 versus Intel's 7894, a 27.5% blowout. Data compression favors AMD at 152168 versus 136497, a 10.3% margin. Data encryption goes AMD's way too, 9051 versus 8128, a 10.2% advantage. Integer math is nearly a tie: 40174 versus 39580, but AMD takes it by 1.5%. Random string sorting is also AMD's, 15294 versus 15191, a slim 0.7% edge.

Looking at the overall average benchmark scores, the AMD Ryzen 5 7235HS sits at 16902, while the Intel Core 3 100U averages 16148. Both chips land in the 70th percentile against all CPUs in the database. Interestingly, the AMD part's nearest rival is the AMD EPYC 7702 with a delta of -0.2%, while the Intel part's closest comparison is the Intel Core i7-10850H at -0.3%. The average score difference is roughly 4.7% in AMD's favor, which suggests that while Intel wins more individual tests, AMD's wins come in benchmarks that carry more weight in the aggregate scoring.

The Verdict

The data paints a picture of two chips with distinct personalities. The Intel Core 3 100U is the general-purpose performer. It wins the Cinebench family outright, meaning it handles standard rendering and multi-threaded creative workloads slightly better. Its 22% lead in single-thread PassMark and 52.6% lead in physics suggest snappier everyday responsiveness and better performance in lightly-threaded applications. The 67.7% advantage in prime number finding is unusual but points to very strong integer execution in that specific pattern.

The AMD Ryzen 5 7235HS is the specialist. Its 27.5% lead in extended instructions makes it the clear choice for workloads that leverage AVX-512 or similar instruction sets. Data compression and encryption are also AMD's territory, with double-digit margins. Anyone dealing with file archives, database workloads, or encrypted data transfer should prefer the AMD part. The 10.3% compression win and 10.2% encryption win are not trivial.

For a laptop buyer choosing between these two, the decision hinges on workload. If the machine runs a mix of office work, web browsing, light content creation, and occasional rendering, the Intel Core 3 100U is the safer pick. Its single-thread advantage (22% in PassMark single-thread) gives it better perceived responsiveness in most daily tasks, and the Cinebench wins confirm it handles creative tools competently. The 15W TDP also suggests it will run cooler and longer on battery, though the database does not record battery life directly.

If the priority is heavy compute with specific instruction sets, or if the workflow involves constant file compression, encryption, or scientific computing, the AMD Ryzen 5 7235HS is the one to choose. Its 45W TDP indicates a higher power envelope, which aligns with its stronger performance in those sustained, demanding workloads. The 76.8 GB/s memory bandwidth recorded for the AMD part is another point in its favor for memory-intensive tasks.

Architecture Differences

Architecturally, these are very different designs. The Intel Core 3 100U is built on Raptor Lake architecture, specifically the Raptor Lake-U codename, using a 10 nm process from Intel's own foundry. The AMD Ryzen 5 7235HS uses Zen 3+ architecture with the Rembrandt-R codename, fabricated on a 6 nm process at TSMC. AMD's die size is recorded at 210 mm²; no die size is recorded for Intel.

Cache layouts differ significantly. Intel uses 80 KB of L1 cache per core, while AMD uses 64 KB per core. Intel's L2 is 1.25 MB per core, AMD's is 512 KB per core. Shared L3 cache also differs: Intel has 10 MB shared, AMD has 8 MB shared. Neither chip has 3D V-Cache.

The AMD part belongs to the 7000 series and its generation is listed as Ryzen 5 (Zen 3+ Rembrandt). Intel's generation is Core 3 (Raptor Lake-U). Both are classified as mobile market segments and both are listed as active in production.

Integrated graphics differ as well: Intel includes UHD Graphics 64EU, while AMD includes Radeon 660M. The AMD chip supports ECC memory, which the Intel chip does not. The database records no transistor counts for either processor.

Where Each One Wins

The Intel Core 3 100U is the winner for general productivity and everyday computing. Its 22% single-thread advantage in PassMark translates to faster application launches and snappier UI responsiveness in most desktop software. The Cinebench wins across R15, R20, and R23, both single and multicore, make it the better choice for content creation involving rendering, video editing, or 3D modeling. The 52.6% physics win suggests it handles simulation and physics-based workloads better. The 67.7% prime number finding win is a curiosity but points to strong performance in specific integer-heavy algorithms.

The 15W TDP of the Intel chip suggests it is designed for thinner, lighter laptops with better battery life, though the database does not record thermal or battery measurements. For a user who wants a capable all-rounder in a portable chassis, the Intel part is the data-backed recommendation.

The AMD Ryzen 5 7235HS wins where instruction-level efficiency matters. The 27.5% extended instructions advantage makes it the pick for scientific computing, cryptography, and any workload that uses advanced SIMD instructions. The 10.3% compression win and 10.2% encryption win make it ideal for database work, file archiving, backup tools, and secure data handling. The integer math win, while small at 1.5%, confirms AMD's strength in general integer operations.

The 45W TDP and 20 PCIe Gen 4 lanes suggest the AMD chip is intended for larger, higher-performance laptops where power draw is less of a concern. Its 76.8 GB/s memory bandwidth gives it an edge in memory-heavy tasks. The 4-core, 8-thread configuration with a 3.20 GHz base clock also indicates a design that favors sustained throughput over burst performance.

For a workstation-class laptop used primarily for compute tasks, the AMD Ryzen 5 7235HS is the clear winner. For a mainstream ultrabook that needs to do a bit of everything well, the Intel Core 3 100U is the better fit. The benchmark data supports both conclusions without ambiguity.
