AMD Ryzen 5 3501U vs AMD Ryzen 7 5800XT Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the AMD Ryzen 7 5800XT wins all 11 shared benchmark comparisons against the AMD Ryzen 5 3501U. The largest margin appears in extended instructions, where the 5800XT scores 24270 versus 3274, a delta of 86.5%. That workload, which exercises advanced x86 instruction set extensions, heavily favors the newer Zen 3 core design.

Data compression follows closely. The 5800XT posts 352002 against the 3501U's 87380, a 75.2% advantage. This is a memory-bandwidth-sensitive test, and the 5800XT's higher memory bandwidth and larger L3 cache contribute directly. Integer math shows a 72% gap (93942 versus 26321), while floating-point math delivers 53808 versus 12707, a 76.4% lead. These are core-count and per-core efficiency differences, not minor clock adjustments.

Multithreaded performance is similarly lopsided. The 5800XT scores 28053 in PassMark multithread versus 7071, a 74.8% delta. The 5800XT's 8 cores and 16 threads versus 4 cores and 4 threads explain the bulk of this. Physics simulation, a heavily threaded workload, shows a 64.4% gap (1355 versus 483). Random string sorting, which tests memory access patterns and cache behavior, yields 35911 versus 10414, a 71% lead.

Single-thread performance narrows the gap but still favors the 5800XT decisively. The 5800XT scores 3535 in PassMark single-thread versus 2136, a 39.6% delta. This is a substantial per-core improvement, not just a core-count artifact. The 5800XT's higher boost clock (4.80 GHz versus 3.70 GHz) and Zen 3 architecture account for this. Data encryption shows 21461 versus 5580, a 74% delta, while prime number finding (a latency-sensitive integer loop) yields 119 versus 21, an 82.4% gap.

The average benchmark score confirms the hierarchy: the 5800XT averages 29879, placing it in the 81st percentile of all CPUs, while the 3501U averages 14320, placing it in the 69th percentile. The 5800XT's nearest rivals include the AMD Ryzen 7 7840H (average 29868, delta 0%) and the AMD Ryzen 7 8845HS (average 29955, delta -0.3%), indicating it sits at a performance plateau among high-end mobile and desktop chips. The 3501U's nearest rivals include the AMD Ryzen Embedded V2546 (average 14336, delta -0.1%) and the AMD Ryzen 3 7320C (average 14277, delta 0.3%), showing it clusters with mid-range embedded and budget mobile parts.

Architecture Differences

The two processors come from different generations and target different segments. The Ryzen 5 3501U is a mobile part from the 3000 series, built on the Zen+ architecture with the Picasso codename. It uses a 12 nm process node fabricated by GlobalFoundries, with 4,940 million transistors on a 210 mm² die. The Ryzen 7 5800XT is a desktop part from the 5000 series, based on Zen 3 with the Vermeer codename. It uses a 7 nm process from TSMC, with 4,150 million transistors on a much smaller 74 mm² die.

The core configurations differ sharply. The 3501U has 4 cores and 4 threads, while the 5800XT has 8 cores and 16 threads. The 5800XT also supports simultaneous multithreading, doubling its thread count. The 3501U does not enable this feature. Base and boost clocks reflect the desktop part's higher power envelope: the 5800XT runs at 3.80 GHz base and 4.80 GHz boost, versus 2.10 GHz base and 3.70 GHz boost for the 3501U.

Cache hierarchies diverge in both size and per-core allocation. The 3501U uses 96 KB of L1 per core and 512 KB of L2 per core, with 4 MB of shared L3. The 5800XT uses 64 KB of L1 per core and 512 KB of L2 per core, but has 32 MB of shared L3. The larger L3 cache on the 5800XT is a key architectural advantage, as it reduces memory latency and improves data reuse in workloads like compression and string sorting. The 3501U's larger L1 per core is a legacy of the Zen+ design, but it does not compensate for the L3 deficit.

Memory support is another differentiator. Both support DDR4 and dual-channel memory, but the 5800XT has a memory bandwidth of 51.2 GB/s versus 38.4 GB/s for the 3501U. The 5800XT also supports ECC memory, while the 3501U does not. PCIe connectivity differs: the 5800XT uses PCIe Gen 4 with 20 lanes (CPU only), while the 3501U uses PCIe Gen 3. This affects storage and GPU bandwidth potential, though the 3501U is a mobile part with integrated graphics.

Integrated graphics split the two clearly. The 3501U includes Radeon Vega 8 graphics, making it a self-contained mobile APU. The 5800XT has no integrated graphics, requiring a discrete GPU. The 5800XT has an unlocked multiplier, while the 3501U does not, reflecting their desktop versus mobile positioning. The 5800XT has a launch MSRP of $249. The 3501U has no recorded launch MSRP in the database.

FAQ

Q: Which processor has the higher single-thread performance?

A: The AMD Ryzen 7 5800XT scores 3535 in PassMark single-thread, versus 2136 for the AMD Ryzen 5 3501U, a 39.6% advantage. The 5800XT's boost clock of 4.80 GHz and Zen 3 architecture drive this difference.

Q: How much larger is the L3 cache on the 5800XT?

A: The 5800XT has 32 MB of shared L3 cache, while the 3501U has 4 MB of shared L3. This 8x difference in L3 capacity is a major factor in memory-intensive workloads like data compression and random string sorting.

Q: Does the 3501U support ECC memory?

A: No. The database lists ECC memory support as false for the 3501U. The 5800XT lists ECC memory support as true.

Q: What is the process node difference between the two chips?

A: The 3501U uses a 12 nm process from GlobalFoundries, while the 5800XT uses a 7 nm process from TSMC. The smaller node contributes to the 5800XT's higher clocks and lower die size (74 mm² versus 210 mm²).

Q: Which processor has integrated graphics?

A: The 3501U includes Radeon Vega 8 integrated graphics. The 5800XT has no integrated graphics, so it requires a separate graphics card.

Q: What is the thread count difference?

A: The 5800XT has 16 threads (8 cores with SMT), while the 3501U has 4 threads (4 cores without SMT). This 4x thread advantage is reflected in multithreaded benchmarks, where the 5800XT leads by 74.8%.

Where Each One Wins

The AMD Ryzen 7 5800XT wins every head-to-head benchmark in the shared set, so the use-case split is defined by margins and context rather than by any 3501U victory.

The 5800XT dominates in heavily threaded and cache-sensitive workloads. Data compression (75.2% lead), integer math (72%), floating-point math (76.4%), and multithreaded tests (74.8%) all favor the 5800XT by wide margins. This makes it the clear choice for rendering, simulation, code compilation, and any workload that scales across 16 threads. Its 32 MB L3 cache and 51.2 GB/s memory bandwidth provide a strong foundation for data processing tasks. The 5800XT also wins single-thread tests by 39.6%, so even lightly threaded applications like legacy games or office software will run faster on this part.

The 3501U has no benchmark wins in the recorded data. Its 15 W TDP and integrated Radeon Vega 8 graphics indicate a design for low-power mobile systems, where the 5800XT's 105 W TDP and lack of integrated graphics are disqualifying. In a thin-and-light laptop, the 3501U's integrated graphics and lower power draw make it viable for basic productivity and media consumption, but the performance data shows it trailing across every metric. The 3501U's 69th percentile ranking versus the 5800XT's 81st percentile confirms that the 5800XT is a higher-performing part overall.

For users who need maximum compute throughput on a desktop, the 5800XT is the unambiguous choice. For users constrained by power or form factor (mobile systems), the 3501U is the only option of the two, but it delivers roughly one-third of the 5800XT's average score (14320 versus 29879). The data does not show any workload where the 3501U closes the gap to parity, so the decision is entirely driven by platform and power requirements, not by performance equivalence.
