AMD Ryzen 3 3100U vs Intel Processor U300L Comparison

Where Each One Wins

The recorded data splits these two processors along very different lines. The AMD Ryzen 3 3100U arrives with a full suite of PassMark benchmark results, covering everything from integer math to data compression. The Intel Processor U300L, by contrast, has no benchmark scores listed in the database at all, which makes direct quantitative comparison impossible for most tests. What the database does show is that the Ryzen 3 3100U holds an average benchmark score of 6247, placing it in the 62nd percentile of all CPUs tracked. The Intel Processor U300L sits in the 50th percentile, but with an average benchmark score of 0 due to missing data.

For workloads where the Ryzen 3 3100U has recorded numbers, it wins outright in every category simply because the Intel part lacks recorded measurements. The Ryzen chip delivers a multithread score of 3348, a single-thread score of 1592, and a floating-point math score of 5854. Its integer math result reaches 8873, while data compression hits 38455. The Intel Processor U300L cannot claim any benchmark win in this dataset, as no scores exist for it. The wins count in the head-to-head section is zero for both parts, confirming that the database holds no direct comparative benchmarks between them.

For users relying purely on measured performance, the Ryzen 3 3100U is the only part with actionable data. The Intel U300L offers no recorded validation of its performance in any PassMark test. That absence does not mean the Intel chip is slower; it simply means the database cannot confirm any advantage for it. The Ryzen part, with its 62nd percentile ranking, sits above the median CPU in the database, while the Intel part, at the 50th percentile with a zero score, effectively lacks a meaningful performance position.

Architecture Differences

The architectural split between these two mobile processors is substantial. The AMD Ryzen 3 3100U belongs to the 3000 series and uses the Picasso codename, built on the Zen+ architecture. It is fabricated by GlobalFoundries on a 12 nm process node, with the die size recorded at 210 mm² and a transistor count of 4,940 million. The Intel Processor U300L uses the Raptor Lake architecture, specifically the Raptor Lake-PS codename, and is built on Intel's 10 nm process node. The Intel chip's die size and transistor count are not recorded in the database.

Core and thread counts differ sharply. The Ryzen 3 3100U has 2 cores and 2 threads, meaning it does not use simultaneous multithreading. The Intel Processor U300L has 5 cores and 6 threads, indicating a hybrid configuration with one efficiency core likely lacking a hyper-threading twin. Clock speeds also diverge. The AMD part runs at a base clock of 1.90 GHz and boosts to 3.20 GHz. The Intel part starts at a lower 1.20 GHz base but boosts much higher to 4.40 GHz. Both are rated at a 15 W TDP, placing them in the same power envelope.

Cache hierarchies are structured differently as well. The Ryzen 3 3100U provides 96 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Intel U300L offers 80 KB of L1 per core, a much larger 1.25 MB of L2 per core, and 8 MB of shared L3 cache, double the AMD part's L3. Memory support also separates them. The Ryzen chip supports DDR4 only, with dual-channel access and a recorded memory bandwidth of 38.4 GB/s. The Intel chip supports both DDR4 and DDR5 memory in a dual-channel configuration, though its memory bandwidth is not listed in the database.

PCIe connectivity differs by generation. The AMD Ryzen 3 3100U uses PCIe Gen 3. The Intel U300L uses PCIe Gen 4 but with only 8 lanes available from the CPU. Integrated graphics also differ: the AMD part carries Radeon Vega 8, while the Intel part uses UHD Graphics 48EU. Neither supports ECC memory. Both are mobile-segment parts with active production status, but their release dates are far apart: the Intel U300L entered the database on April 7, 2024, while the Ryzen 3 3100U has a release date of May 31, 2026.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two processors. The head-to-head section is empty, and the wins counter shows zero for both parts. This means the comparison must rely on the Ryzen 3 3100U's standalone results and the Intel U300L's absence of recorded scores.

Looking at the Ryzen 3 3100U's individual PassMark results, the data shows a processor with clear strengths in certain workloads. Its data compression score of 38455 is by far its highest recorded result, suggesting strong performance in archiving or compression-heavy tasks. The integer math score of 8873 also stands out, as does the random string sorting score of 4666. The floating-point math result of 5854 indicates moderate capability for numerical workloads. The extended instructions score of 2116 and data encryption score of 1972 are more modest. The find prime numbers score of 18 is very low, as is the physics score of 232, suggesting weak performance in those specific calculations.

The multithread score of 3348 and single-thread score of 1592 provide baseline context. With only 2 cores and 2 threads, the Ryzen part cannot leverage parallel workloads as effectively as higher-core-count parts, yet its single-thread score indicates decent per-core performance for a 12 nm mobile chip. The Intel U300L, with 5 cores and 6 threads and a 4.40 GHz boost clock, would likely outperform the Ryzen part in multithreaded tasks based on its core count and clock advantage, but the database provides no scores to confirm this. The Intel chip's higher boost clock suggests superior single-thread performance, but again, no measured data exists.

The nearest rivals for the Ryzen 3 3100U provide some context for its average score. The AMD Ryzen Threadripper 1950X scores 6231, a 0.3% difference from the Ryzen 3 3100U's 6247. The AMD EPYC 7272 scores 6186, a 1% difference. The Intel Core i9-10920X scores 6347, which is 1.6% higher than the Ryzen part. The Intel Core i9-7940X scores 6147, 1.6% lower. These rivals are all far higher-end desktop and server parts, yet the Ryzen 3 3100U's average score lands squarely among them, indicating that its aggregate benchmark performance is comparable to those much larger chips despite its mobile positioning.

The Verdict

The data supports a clear split. For anyone choosing between these two parts based on recorded measurements, the AMD Ryzen 3 3100U is the only option with verified performance numbers. It posts an average benchmark score of 6247, ranks in the 62nd percentile of all CPUs, and delivers results across eleven PassMark tests. The Intel Processor U300L has no recorded benchmarks, no average score beyond zero, and sits at the 50th percentile by default.

For single-threaded workloads, the Intel part's 4.40 GHz boost clock versus the Ryzen's 3.20 GHz suggests an advantage, but the database cannot confirm it. For multithreaded workloads, the Intel part's 5 cores and 6 threads versus the Ryzen's 2 cores and 2 threads point in the same direction, yet again no scores exist. The Ryzen 3 3100U's 2-core, 2-thread configuration is a clear limitation for modern parallel workloads, and its 12 nm process node is older than the Intel part's 10 nm node.

The Intel U300L's 8 MB of L3 cache doubles the Ryzen's 4 MB, and its support for both DDR4 and DDR5 memory gives it more flexibility. The Ryzen part's 38.4 GB/s memory bandwidth is recorded, while the Intel part's is not, so direct memory throughput comparison is unavailable. The Intel chip also uses PCIe Gen 4, while the AMD chip uses Gen 3, which matters for storage and expansion bandwidth.

Strictly from the data, the Ryzen 3 3100U is the part with proven performance in the database. Its average score of 6247 and 62nd percentile ranking provide a concrete reference point. The Intel Processor U300L remains an unmeasured quantity. Users who require validated benchmark data should select the Ryzen 3 3100U. Users who prioritize core count, cache size, and memory flexibility, and who are willing to accept a lack of recorded performance, may consider the Intel U300L. The launch MSRP for the Intel part is $107, which can be stated once as a reference, but no performance justification exists in the database to support a purchase decision based on measured results.
