AMD Ryzen 3 5305G vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark comparisons between the AMD Ryzen 3 5305G and the Intel Arc G3. The head-to-head benchmark set is empty, and neither processor has any individual benchmark scores listed. The win counts are zero for both sides. This means the data offers no measured performance deltas, no multi-core or single-core score differences, and no percentile shifts between the two parts.

What the database does provide is structural positioning. Both processors sit at the 50th percentile against all CPUs tracked in the database. That places them at the midpoint of the recorded performance distribution, though without actual scores, the percentile alone cannot indicate how close they are to each other or to the median. The absence of benchmark data means any direct comparison of speed, throughput, or responsiveness must remain qualitative. The only concrete numbers available are specifications, which show two very different designs aimed at different market segments.

The Ryzen 3 5305G is a desktop part with a base clock of 4.00 GHz and a boost clock of 4.20 GHz. The Arc G3 is a mobile part with a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The boost clock advantage for Intel is 0.40 GHz, but the base clock advantage for AMD is 2.10 GHz. These clock figures suggest different operating behaviors: the AMD chip sustains higher frequencies under load, while the Intel part relies on a lower idle base and a higher peak boost. Without benchmark scores, the practical impact of these clocks on real workloads cannot be quantified from the database.

The core and thread counts differ sharply. The Ryzen 3 5305G uses 4 cores and 8 threads, while the Arc G3 uses 14 cores and 14 threads. The Intel part has 10 more cores but 6 more threads, indicating that AMD uses simultaneous multithreading while Intel does not. The thread count parity with the core count for Intel suggests each core handles a single thread, whereas AMD doubles its thread capacity per core. This architectural difference could favor AMD in heavily threaded workloads that benefit from extra logical processors, though the database records no scores to confirm this.

Cache configurations also diverge. The Ryzen 3 5305G carries 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. The Arc G3 carries 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part has three times the L1 per core, roughly five times the L2 per core, and more than double the L3. Larger caches typically reduce memory latency and improve hit rates, but again, no benchmark data exists to translate these differences into performance outcomes.

Memory bandwidth favors Intel substantially. The Arc G3 supports LPDDR5X with a recorded bandwidth of 136.5 GB/s over a dual-channel bus. The Ryzen 3 5305G supports DDR4 with a recorded bandwidth of 51.2 GB/s over a dual-channel bus. The Intel part shows a bandwidth advantage of 85.3 GB/s, which is about 2.7 times the AMD figure. This could matter for memory-intensive tasks such as data compression, large dataset processing, or integrated graphics workloads, though the database does not include tests that verify this.

The Verdict

The data does not support a performance verdict because no benchmark scores exist for either processor. The database shows both at the 50th percentile, but that percentile is not tied to any measured average score. Without scores, the percentile is an empty label. The verdict must therefore rest on specification differences and market positioning.

The Ryzen 3 5305G targets desktop systems with an AMD Socket AM4 platform, a 65 W TDP, and a 7 nm process from TSMC. It uses the Zen 3 architecture with the Cezanne codename. The Intel Arc G3 targets mobile systems with an Intel BGA 2540 socket, a 25 W TDP, and a 3 nm process from Intel. It uses the Panther Lake codename with the Arc G3 generation label. The TDP difference is 40 W in favor of Intel, indicating the mobile part is designed for lower power envelopes. The process node difference is 4 nm in favor of Intel, suggesting a denser transistor geometry.

The Ryzen 3 5305G offers an unlocked multiplier, which the database records as true. The Arc G3 has a locked multiplier. This means the AMD part allows overclocking, while the Intel part does not. For users who adjust clock speeds manually, this is a decisive specification difference. The AMD part also uses PCIe Gen 3 with 16 lanes from the CPU, while the Intel part uses PCIe Gen 5 with 4 lanes from the CPU. The generation difference favors Intel, but the lane count favors AMD. The practical effect depends on the devices connected, which the database does not specify.

Integrated graphics differ as well. The Ryzen 3 5305G uses Radeon Vega 6. The Arc G3 uses Arc B370. Neither has benchmark scores in the database, so their relative graphics performance cannot be stated with numbers. The memory bandwidth difference of 85.3 GB/s in favor of Intel could benefit its integrated graphics, but this remains an inference from specifications, not a measured result.

Architecture Differences

The two processors come from different architectural lineages. The Ryzen 3 5305G uses the Zen 3 architecture with the codename Cezanne, part of the 5000 series. The Intel Arc G3 uses the Panther Lake codename with the Arc G3 generation label. The database does not list a specific architecture name for Intel, only the codename and generation.

The process nodes differ: AMD uses 7 nm from TSMC, while Intel uses 3 nm from its own foundry. The AMD chip has a recorded transistor count of 10,700 million and a die size of 180 mm². The Intel chip has no transistor count or die size recorded in the database. This makes a direct density comparison impossible from the available facts.

Core organization differs in type and scale. The Ryzen 3 5305G has 4 cores and 8 threads, so each core supports two threads. The Intel Arc G3 has 14 cores and 14 threads, so each core supports one thread. The thread-to-core ratio is 2.0 for AMD and 1.0 for Intel. This indicates the AMD part relies on simultaneous multithreading to increase logical processor count, while the Intel part does not.

Cache hierarchy differs in per-core and shared allocations. For L1, AMD provides 64 KB per core while Intel provides 192 KB per core. For L2, AMD provides 512 KB per core while Intel provides 2.5 MB per core. For L3, AMD provides 8 MB shared while Intel provides 18 MB shared. The Intel part has larger allocations at every cache level.

Memory support differs in type and bandwidth. AMD supports DDR4 with 51.2 GB/s. Intel supports LPDDR5X with 136.5 GB/s. Both use dual-channel buses. The memory type difference reflects the market split: desktop typically uses DDR4, mobile typically uses LPDDR5X. Neither processor supports ECC memory, as the database records false for both.

PCIe capabilities differ in generation and lane count. AMD provides Gen 3 with 16 lanes from the CPU. Intel provides Gen 5 with 4 lanes from the CPU. The generation advantage belongs to Intel, the lane count advantage belongs to AMD. The socket types also differ: AMD uses Socket AM4, Intel uses BGA 2540. The BGA designation indicates a soldered mobile part, while AM4 is a socketed desktop design.

Specification Differences

The two processors differ in nearly every major specification field. The Ryzen 3 5305G uses 4 cores and 8 threads. The Intel Arc G3 uses 14 cores and 14 threads. Base clocks are 4.00 GHz for AMD and 1.90 GHz for Intel. Boost clocks are 4.20 GHz for AMD and 4.60 GHz for Intel. TDP is 65 W for AMD and 25 W for Intel.

The AMD part has a 7 nm process node from TSMC and a transistor count of 10,700 million on a 180 mm² die. The Intel part has a 3 nm process node from Intel with no recorded transistor count or die size. Cache sizes differ at every level: 64 KB versus 192 KB L1 per core, 512 KB versus 2.5 MB L2 per core, and 8 MB versus 18 MB L3 shared.

Memory support differs by type and bandwidth: DDR4 at 51.2 GB/s for AMD, LPDDR5X at 136.5 GB/s for Intel. Both use dual-channel buses. PCIe differs by generation and lanes: Gen 3 with 16 lanes for AMD, Gen 5 with 4 lanes for Intel. Integrated graphics differ: Radeon Vega 6 for AMD, Arc B370 for Intel.

The market segments differ: Desktop for AMD, Mobile for Intel. Sockets differ: AMD Socket AM4 versus Intel BGA 2540. The multiplier is unlocked for AMD and locked for Intel. Release dates differ: 2025-02-23 for AMD and 2026-05-27 for Intel. Part numbers differ: 100-000001802 for AMD and SA4QZ for Intel. Neither part has a launch MSRP recorded in the database.
