AMD Ryzen 5 3501U vs Intel Core Ultra 7 265F Comparison

The AMD Ryzen 5 3501U and Intel Core Ultra 7 265F occupy completely different performance strata, as reflected in their database positions: the Ryzen sits at the 69th percentile of all CPUs, while the Ultra 7 lands at the 93rd percentile. Across the eleven shared benchmark workloads, the Intel part wins every single contest, often by margins exceeding 80%. This is not a close comparison; it is a matchup between a 15-watt mobile processor designed for efficiency and a 65-watt desktop processor designed for throughput.

Where Each One Wins

The benchmark data is unambiguous: the Intel Core Ultra 7 265F wins in every recorded workload category. The Ryzen 5 3501U does not secure a single victory across the eleven head-to-head tests. This complete sweep means the use-case split is defined not by which processor has advantages, but by the nature of the tasks each can realistically handle given their respective platforms and power envelopes.

The Ryzen 5 3501U is a mobile processor with a 15-watt TDP, aimed at thin-and-light laptops. Its performance profile, with a PassMark multi-thread score of 7071 and a single-thread score of 2136, is sufficient for everyday productivity, web browsing, and light multitasking. The presence of integrated Radeon Vega 8 graphics means it can handle basic display output and video playback without a discrete GPU. The data indicates it is not designed for heavy compute loads, as its physics score of 483 and floating-point math score of 12707 are modest.

The Intel Core Ultra 7 265F is a desktop processor with a 65-watt TDP. It has no integrated graphics, requiring a discrete GPU, but its raw compute power is in a different league. Its multi-thread score of 49410 is nearly seven times higher than the Ryzen's, and its single-thread score of 4750 is more than double. This positions it for demanding desktop workloads such as content creation, software compilation, and high-end gaming, where the extra cores and clock speed translate directly into faster completion times. The data confirms that the Ultra 7 is the only choice for compute-intensive tasks, while the Ryzen is the only option for low-power mobile systems.

Architecture Differences

The two processors are built on fundamentally different architectures, reflecting their distinct market positions. The AMD Ryzen 5 3501U uses the Picasso architecture, which is based on the older Zen+ microarchitecture. It is manufactured on a 12 nm process at GlobalFoundries, with 4,940 million transistors on a 210 mm² die. It features 4 cores and 4 threads, with a base clock of 2.10 GHz and a boost clock of 3.70 GHz. Its cache hierarchy includes 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. Memory support is limited to DDR4 over a dual-channel bus, providing a memory bandwidth of 38.4 GB/s. It uses PCIe Gen 3 and is socketed for AMD Socket FP5.

The Intel Core Ultra 7 265F uses the Arrow Lake architecture, specifically Arrow Lake-S. It is manufactured on a 3 nm process at TSMC, with 17,800 million transistors on a 243 mm² die. It features 20 cores and 20 threads, with a base clock of 2.40 GHz and a boost clock of 5.30 GHz. Its cache layout is larger: 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. It supports DDR5 memory over a dual-channel bus, yielding a memory bandwidth of 102.4 GB/s. It uses PCIe Gen 5 with 20 lanes from the CPU and fits into Intel Socket 1851.

The process node difference is stark: 12 nm versus 3 nm. This contributes to the Intel part's ability to pack 20 cores and a much larger cache into a similar die area. The transistor count difference, 4,940 million versus 17,800 million, is also indicative of the generational leap. The Ryzen uses a monolithic design typical of its era, while the Ultra 7's Arrow Lake architecture is a newer design that enables higher core counts and faster memory interfaces.

Head-to-Head Benchmarks

The largest performance gap appears in the PassMark extended instructions test. The Intel Core Ultra 7 265F scores 39235, while the AMD Ryzen 5 3501U scores 3274, a delta of -91.7% for the Ryzen. This means the Intel part processes extended instruction sets, such as AVX-512 or similar, at nearly twelve times the throughput. This is a critical advantage for scientific computing and cryptography workloads.

The data compression test shows a similar disparity. The Ultra 7 scores 507018, compared to the Ryzen's 87380, a delta of -82.8%. This indicates the Intel processor compresses data at roughly 5.8 times the speed, a significant factor for database operations and file archiving. The encryption test follows the same pattern: the Ultra 7 scores 39468 versus 5580 for the Ryzen, a delta of -85.9%, showing the Intel part decrypts and encrypts data over seven times faster.

The floating-point math test is another massive win for Intel. The Ultra 7 scores 173855, against 12707 for the Ryzen, a delta of -92.7%. This is a 13.7x advantage, which is crucial for 3D rendering, physics simulations, and financial modeling. The integer math test shows an 80.9% delta, with scores of 138078 versus 26321, a 5.2x difference, relevant for general computing and database indexing.

The single-thread test is the closest comparison. The Ultra 7 scores 4750, while the Ryzen scores 2136, a delta of -55%. This still represents a 2.2x advantage for Intel, meaning even lightly threaded applications will run more than twice as fast on the desktop part. The multi-thread test shows a delta of -85.7%, with scores of 49410 versus 7071, a 7x difference, which is the expected result given the 20-core versus 4-core configuration.
