AMD Ryzen 5 3501U vs AMD Ryzen 9 270 Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the AMD Ryzen 9 270, winning all 11 head-to-head benchmark comparisons. The Ryzen 5 3501U does not secure a single victory in any measured workload. The most lopsided margin appears in extended instructions, where the Ryzen 9 270 scores 26729 against 3274, a delta of -87.8%. This indicates a massive advantage in workloads that leverage advanced instruction sets, likely reflecting both architectural and microarchitectural improvements.

In data compression, the Ryzen 9 270 delivers 351398 versus 87380, a -75.1% delta. The Ryzen 5 3501U trails by a similar margin in encryption, scoring 5580 against 20852, a -73.2% difference. Integer math shows the same pattern: 98266 for the Ryzen 9 270 against 26321, again -73.2%. Floating point math widens the gap further, with 60122 versus 12707, a -78.9% delta.

Multithreaded performance is decisively in favor of the Ryzen 9 270. The passmark_multithread score of 29089 dwarfs the 7071 posted by the Ryzen 5 3501U, a -75.7% delta. Prime number finding follows the trend at 88 versus 21, -76.1%. Random string sorting shows 42819 against 10414, -75.7%, matching the multithread delta exactly.

The smallest relative gap appears in single-thread performance. The Ryzen 9 270 scores 3784 in passmark_single_thread, while the Ryzen 5 3501U manages 2136, a -43.6% delta. This is still a substantial lead, but it confirms that the Ryzen 9 270's advantage is more pronounced in heavily parallel workloads than in lightly threaded ones. Physics simulation shows a -64.6% delta, with 1365 versus 483, the second smallest margin after single-thread tests.

The average benchmark score reinforces the hierarchy: the Ryzen 9 270 sits at 40246, while the Ryzen 5 3501U averages 14320. The percentile ranking separates them as well, with the Ryzen 9 270 at the 87th percentile of all CPUs and the Ryzen 5 3501U at the 69th.

Architecture Differences

These two processors come from different design eras and foundries. The Ryzen 5 3501U uses the Picasso codename, based on the Zen+ architecture, and is fabricated on a 12 nm process at GlobalFoundries. The Ryzen 9 270 uses the Hawk Point codename, based on Zen 4, and is built on a 4 nm process at TSMC. The process node difference is substantial, representing a significant reduction in feature size between generations.

Transistor counts reflect the generational leap. The Ryzen 5 3501U contains 4,940 million transistors on a 210 mm² die. The Ryzen 9 270 packs 25,000 million transistors on a smaller 178 mm² die. The higher transistor density on a smaller die highlights the manufacturing advantage of the 4 nm node.

Core and thread configuration differs sharply. The Ryzen 5 3501U offers 4 cores and 4 threads, while the Ryzen 9 270 doubles both to 8 cores and 16 threads. Clock speeds also favor the newer part: the Ryzen 5 3501U has a base clock of 2.10 GHz and a boost of 3.70 GHz, while the Ryzen 9 270 starts at 4.00 GHz and boosts to 5.20 GHz.

Cache hierarchies are structured differently. The Ryzen 5 3501U uses 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Ryzen 9 270 uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Although per-core L1 is smaller on the Ryzen 9 270, total L2 capacity is higher due to more cores, and L3 is quadrupled.

Memory support diverges completely. The Ryzen 5 3501U supports DDR4 with dual-channel memory and 38.4 GB/s of bandwidth. The Ryzen 9 270 supports DDR5 with dual-channel memory and 89.6 GB/s of bandwidth. Neither supports ECC memory. PCIe capabilities also differ, with the Ryzen 5 3501U limited to Gen 3 and the Ryzen 9 270 offering Gen 4 with 20 lanes for the CPU.

Integrated graphics differ as well. The Ryzen 5 3501U uses Radeon Vega 8, while the Ryzen 9 270 uses Radeon 780M. The sockets are incompatible: AMD Socket FP5 for the older part and AMD Socket FP8 for the newer one. The Ryzen 9 270 has a TDP of 45 watts, while the Ryzen 5 3501U is rated at 15 watts. Neither processor has an unlocked multiplier.

Where Each One Wins

The data shows no benchmark category where the Ryzen 5 3501U wins. The Ryzen 9 270 takes every recorded test. However, the magnitude of the margins varies, which informs how each processor handles different workloads.

The Ryzen 9 270 is strongest relative to the Ryzen 5 3501U in extended instructions, where the -87.8% delta represents its largest advantage. This suggests workloads such as cryptography, SIMD-heavy computation, or specialized instruction sequences benefit enormously from the Zen 4 architecture. Floating point math also shows a very wide gap at -78.9%, indicating strong performance in scientific or analytical calculations.

Multithreaded workloads favor the Ryzen 9 270 heavily, with deltas of -75.7% in both multithread and random string sorting, and -76.1% in prime number finding. The combination of twice the cores, twice the threads, and higher clocks drives these results. The Ryzen 5 3501U, with only 4 threads, cannot compete in parallel processing scenarios.

Single-thread performance is the closest comparison, with a -43.6% delta. While the Ryzen 9 270 still wins clearly, the smaller gap means that the Ryzen 5 3501U is relatively less disadvantaged in lightly threaded applications such as basic office tasks or legacy software that uses one core. Physics simulation, at -64.6%, falls between the extremes.

The Ryzen 5 3501U's lower TDP of 15 watts versus 45 watts suggests it may be found in systems prioritizing low power draw, but no power efficiency benchmarks are present in the data to confirm a performance-per-watt advantage. The benchmark results themselves provide no win for the older part.

The Verdict

The benchmark data leaves no ambiguity about the performance hierarchy. The AMD Ryzen 9 270 wins every recorded comparison, with an average benchmark score of 40246 against 14320 for the AMD Ryzen 5 3501U. The Ryzen 9 270 also sits higher in the overall CPU percentile ranking at 87 versus 69.

The Ryzen 9 270 is the choice for any workload that benefits from multi-core parallelism, extended instruction sets, or high memory bandwidth. Its 8 cores and 16 threads, combined with a 5.20 GHz boost clock and 16 MB of L3 cache, produce dominant results in compression, encryption, math operations, and sorting tasks. The nearest rivals to the Ryzen 9 270 include the Intel Core i9-13905H at a -0.2% delta and the AMD Ryzen 7 7700 at 0.4%, placing it in strong company among high-end processors.

The Ryzen 5 3501U, with its 4 cores, 4 threads, and 15 watt TDP, occupies a lower performance tier. Its nearest rivals include the AMD Ryzen 3 7320C at 0.3% and the Intel Core i5-10400F at 1%, showing it competes with entry-level and older mid-range parts. The data indicates the Ryzen 5 3501U is best suited for scenarios where its modest power envelope is the primary consideration, though no efficiency benchmarks in the database confirm this tradeoff quantitatively.

For users prioritizing raw compute performance, the Ryzen 9 270 is the clear selection based on every metric in the database. For those constrained to a 15 watt platform, the Ryzen 5 3501U remains the only option of the two, but it cannot match the Ryzen 9 270 in any measured workload. The architectural gap between Zen+ on 12 nm and Zen 4 on 4 nm is reflected in the consistent, often massive, deltas across all benchmark categories.
