AMD Ryzen 5 5600XT vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen 5 5600XT, winning 14 of the 17 head-to-head benchmark comparisons. The Intel Core 3 305 manages only 3 wins, all in specific single-thread or floating-point workloads.

The most pronounced gap appears in integer math operations. The AMD Ryzen 5 5600XT scores 71,063 versus 32,295 for the Intel Core 3 305, a delta of 120%. This is the largest percentage difference in the entire comparison set, indicating a substantial advantage in workloads that rely heavily on integer processing.

Cinebench results reinforce the AMD advantage consistently. Across all three versions of Cinebench (R15, R20, R23), the multicore scores show a delta of 42.7% in favor of the AMD chip. For example, in Cinebench R23 multicore, the AMD scores 18,724 while the Intel scores 13,123. Single-core Cinebench results follow a similar pattern, with deltas ranging from 42.7% to 43% across the different versions. In Cinebench R15 single-core, the AMD scores 266 versus 186 for the Intel part, a 43% advantage.

Data compression results show the AMD processor at 257,118 compared to 146,857 for the Intel, which translates to a 75.1% delta. This suggests the AMD chip handles compression workloads with notably higher efficiency. Similarly, random string sorting shows a 51.5% delta in favor of AMD, with scores of 26,693 versus 17,623.

The Intel Core 3 305 does claim two significant wins. In PassMark single-thread performance, the Intel scores 3,977 versus 3,469 for the AMD chip, a delta of -12.8% (meaning AMD trails by that margin). This is a clear indicator that the Intel part has superior raw single-core throughput in this specific test. Additionally, in floating-point math, the Intel scores 42,284 versus 40,537 for AMD, a smaller delta of -4.1%.

The third Intel win comes in the duplicate PassMark single-thread test, which records the same scores as the primary single-thread test. The remaining benchmarks, including data encryption (44.7% delta), multithread (44.3% delta), extended instructions (28.8% delta), and prime number finding (24.3% delta), all favor the AMD processor. Physics performance shows a modest 7.2% advantage for AMD, with scores of 1,322 versus 1,233.

Where Each One Wins

The AMD Ryzen 5 5600XT dominates in virtually every multithreaded scenario. Its 12 threads versus 6 threads for the Intel part provide a clear structural advantage. Cinebench multicore tests, PassMark multithread, data compression, encryption, integer math, and random string sorting all fall into the AMD column. These workloads benefit from simultaneous multithreading, which allows the AMD chip to process more instructions in parallel.

The Intel Core 3 305 shows its strengths in single-threaded performance. The PassMark single-thread score of 3,977 represents the highest single score in that category for either processor. This indicates that for applications that cannot utilize multiple cores effectively, the Intel part may offer better responsiveness. The floating-point math win, though narrower, suggests the Intel architecture handles certain mathematical operations with greater efficiency.

For mixed workloads, the AMD processor's physics score (1,322 versus 1,233) shows it also handles simulated physical calculations reasonably well. The extended instructions benchmark, which tests vector and SIMD operations, favors AMD by 28.8%, indicating strong performance in modern instruction set extensions.

The pattern is clear: AMD wins productivity and multi-threaded tasks by wide margins, while Intel wins narrowly in specific single-thread and floating-point scenarios. Users prioritizing parallel workloads should favor AMD, while those focused on lightly threaded applications might find the Intel part's single-core performance appealing.

Architecture Differences

The two processors come from different manufacturing and design philosophies. The AMD Ryzen 5 5600XT uses the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. It contains 4,150 million transistors on a 74 mm² die. The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process at Intel's own foundry, with transistor count and die size not recorded in the database.

Core and thread counts differ significantly. Both have 6 physical cores, but the AMD processor supports 12 threads through simultaneous multithreading, while the Intel part has 6 threads total. This explains the large multicore performance delta.

Cache configurations are notably different. The AMD chip has 64 KB of L1 cache per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. The Intel part has 192 KB of L1 cache total, 2.5 MB of L2 total, and 6 MB of shared L3 cache. The AMD processor's larger cache hierarchy supports its higher throughput in cache-sensitive workloads.

Memory support also diverges. The AMD Ryzen 5 5600XT supports DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth. The Intel Core 3 305 supports DDR5 and LPDDR5X memory but uses a single-channel bus, though it achieves 59.7 GB/s bandwidth. The AMD chip supports ECC memory, while the Intel part does not.

The AMD processor uses AMD Socket AM4 and is unlocked for overclocking. The Intel processor uses Intel BGA 1516, is not multiplier-unlocked, and is classified as a mobile part. The AMD chip has no integrated graphics, while the Intel part includes Intel Xe3 Graphics with 1 Xe core. PCIe support shows the AMD part with 20 lanes on Gen 4, while the Intel part has 6 lanes on Gen 4.

The AMD processor operates with a base clock of 3.70 GHz and boost clock of 4.70 GHz, with a 65 W TDP. The Intel processor has a 1.50 GHz base clock and 4.30 GHz boost clock, with a 15 W TDP. The release dates differ substantially, with AMD launching on 2024-10-30 and Intel on 2026-04-15.

The 12-thread capability versus 6 threads provides a fundamental advantage that the benchmark scores confirm.

The Intel Core 3 305 offers a different profile. Its 15 W TDP makes it suitable for mobile platforms, and its single-thread PassMark score of 3,977 exceeds the AMD part by 12.8%. Applications that rely heavily on single-thread performance, such as certain legacy software or lightly threaded games, could see better performance from the Intel chip. The integrated graphics also provides a display output capability that the AMD part lacks.

The AMD processor's 81st percentile ranking versus the Intel's 72nd percentile reflects the overall performance gap. The AMD part's nearest rivals include high-end mobile H-series chips like the Core i9-13900H, while the Intel part's rivals are more modest desktop parts like the Core i3-14100.

For users building a desktop system with an AM4 motherboard, the AMD Ryzen 5 5600XT delivers superior multi-threaded performance and a larger cache configuration. For mobile users prioritizing power efficiency and single-thread speed, the Intel Core 3 305 provides a lower power envelope and better single-thread PassMark scores, but it trails significantly in multithreaded workloads.
