Architecture Differences

The AMD Ryzen 5 5605G belongs to the 5000 series and uses the Zen 3 architecture with the Cezanne codename. It is built on a 7 nm TSMC process with 10,700 million transistors on a 180 mm² die. The Intel Core Ultra 3 205 comes from the Core Ultra Series 2 and uses the Arrow Lake architecture with the Arrow Lake-S codename. It is fabricated on a 3 nm TSMC process with 17,800 million transistors on a 243 mm² die.

The cache hierarchies differ substantially. The AMD chip provides 64 KB of L1 cache per core and 512 KB of L2 cache per core, with a 16 MB L3 cache. The Intel chip offers 192 KB of L1 cache per core and 3 MB of L2 cache per core, with a 15 MB shared L3 cache. The Intel part has significantly more L2 cache per core, which can benefit workloads that repeatedly access the same data sets.

Memory support marks another major architectural divergence. The AMD Ryzen 5 5605G uses DDR4 memory on a dual-channel bus with 51.2 GB/s bandwidth. The Intel Core Ultra 3 205 uses DDR5 memory on a dual-channel bus with 102.4 GB/s bandwidth, doubling the theoretical memory throughput. Neither processor supports ECC memory.

PCIe capabilities also differ. The AMD chip provides PCIe Gen 3 with 16 lanes from the CPU, while the Intel chip provides PCIe Gen 5 with 20 lanes from the CPU. This gives the Intel part both a newer PCIe generation and more available lanes for expansion devices.

The socket platforms are completely different. The AMD part uses AMD Socket AM4, while the Intel part uses Intel Socket 1851. The AMD processor has an unlocked multiplier, allowing overclocking, while the Intel processor has a locked multiplier.

The integrated graphics solutions come from different vendors. AMD uses its Radeon Vega 7, while Intel uses its Arc Xe-LPG Graphics 16EU. Both provide display output capabilities without a discrete graphics card.

Where Each One Wins

The database contains benchmark results for the Intel Core Ultra 3 205, while no benchmark scores are recorded for the AMD Ryzen 5 5605G. This means the head-to-head comparison relies on the Intel part's recorded performance across Cinebench and PassMark tests, along with the architectural and specification differences between the two.

The AMD Ryzen 5 5605G wins in thread count with 12 threads versus 8, which helps in heavily threaded workloads that can use more than 8 execution contexts. Its higher base clock of 3.90 GHz compared to 3.80 GHz gives it a slight frequency advantage at stock settings. The unlocked multiplier on the AMD part allows users to push clock speeds beyond the factory boost, a capability the Intel part does not offer.

The Intel Core Ultra 3 205 wins in raw multi-core performance based on its benchmark scores. Its Cinebench R23 multi-core score of 19856 demonstrates strong parallel throughput. The Intel part also wins in memory bandwidth with 102.4 GB/s versus 51.2 GB/s, which benefits memory-intensive applications such as large dataset processing and data compression workloads. Its PassMark data compression score of 260651 reflects this advantage.

The Intel part holds a decisive lead in single-threaded performance. Its Cinebench R23 single-core score of 2803 and PassMark single-thread score of 4575 indicate strong per-core efficiency. The higher boost clock of 4.90 GHz contributes to this result. The Intel part also wins in PCIe connectivity with Gen 5 and 20 lanes, which matters for users connecting high-bandwidth NVMe storage or GPUs.

The AMD part wins in power efficiency per thread. It has a 65 W TDP with 12 threads, while the Intel part has a 57 W TDP with 8 threads. However, the Intel part delivers higher performance per watt in the recorded benchmarks, given its substantially higher scores at a lower TDP.

Head-to-Head Benchmarks

The Intel Core Ultra 3 205 has recorded benchmark scores across Cinebench and PassMark suites. The AMD Ryzen 5 5605G has no recorded scores in the database, so the following analysis covers the Intel part's absolute results and its standing relative to its nearest rivals.

In Cinebench R23 multi-core, the Intel part scores 19856. This places it in the upper tier of desktop processors, with its average benchmark score of 31473 matching the Intel Core 7 240H at a 0% delta. The AMD Ryzen 9 5980HX scores 31495, a 0.1% difference from the Intel Core Ultra 3 205. The Intel Core Ultra 5 225H scores 31508, also 0.1% higher, and the Intel Core i5-13500 scores 31510, again 0.1% higher. These rival comparisons suggest the Core Ultra 3 205 performs at parity with a range of higher-tier mobile and desktop chips despite its entry-level positioning.

In Cinebench R23 single-core, the Intel part scores 2803. This strong single-thread result aligns with its 4.90 GHz boost clock and explains its high percentile ranking of 82 among all CPUs. The single-core score indicates that the Arrow Lake architecture delivers excellent per-core efficiency, which benefits responsiveness in lightly threaded applications.

The PassMark multi-thread score of 26167 confirms the Intel part's parallel processing capability. Its data compression score of 260651 is the highest PassMark result recorded for this chip, showing particular strength in compression workloads. Floating point math scores 75136, while integer math scores 54755. Extended instructions score 22578, which covers SIMD workloads such as multimedia encoding and scientific calculations. Random string sorting scores 31083, and data encryption scores 18772. Find prime numbers scores 268, which is a relatively modest result for this specific prime-number search workload.

The Cinebench R20 results show a multi-core score of 8339 and a single-core score of 1177. The Cinebench R15 results show a multi-core score of 2001 and a single-core score of 282. These older benchmark versions confirm the same pattern: the Intel part delivers strong multi-threaded throughput and excellent single-thread performance.

The PassMark physics score of 2016 and the single-thread score of 4575 complete the picture. The physics score reflects gaming-related CPU physics calculations, while the single-thread score is a direct measure of per-core speed. Both results are competitive with the nearest rivals listed in the database.

The AMD Ryzen 5 5605G's absence of recorded benchmark data means its performance cannot be directly quantified against the Intel part. However, the architectural differences suggest the Intel chip will hold advantages in memory-bound workloads due to its doubled bandwidth, in single-threaded tasks due to its higher boost clock, and in PCIe-dependent applications due to its Gen 5 support. The AMD chip's 12 threads and unlocked multiplier provide flexibility for overclocking and for workloads that scale with thread count beyond 8 threads.
