Architecture Differences

The AMD Ryzen 3 5305G belongs to the 5000 series and uses the Zen 3 architecture under the Cezanne codename. It is built on a 7 nm process by TSMC with 10,700 million transistors on a 180 mm² die. The Intel Core Ultra 5 225T belongs to the Core Ultra Series 2 and uses the Arrow Lake architecture under the Arrow Lake-S codename. It is built on a 3 nm process by TSMC with 17,800 million transistors on a 243 mm² die.

The core configuration differs fundamentally. The AMD part has 4 cores with 8 threads, meaning each core supports two threads. The Intel part has 10 cores with 10 threads, meaning each core supports exactly one thread. This reflects a design choice where Intel prioritizes physical core count over simultaneous multithreading.

Cache hierarchies are also distinct. The AMD Ryzen 3 5305G has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 8 MB of L3 cache. The Intel Core Ultra 5 225T has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 20 MB of shared L3 cache. The Intel part has significantly larger per-core L2 cache and more than double the L3 cache.

Memory support differs by generation. The AMD part uses DDR4 with dual-channel configuration and 51.2 GB/s bandwidth. The Intel part uses DDR5 with dual-channel configuration and 102.4 GB/s bandwidth. Neither CPU supports ECC memory.

PCIe connectivity also differs. The AMD Ryzen 3 5305G provides PCIe Gen 3 with 16 lanes from the CPU. The Intel Core Ultra 5 225T provides PCIe Gen 5 with 20 lanes from the CPU. This gives the Intel part a newer generation and more lanes.

The socket platforms are incompatible. The AMD part uses AMD Socket AM4, while the Intel part uses Intel Socket 1851. The AMD part has an unlocked multiplier, while the Intel part is locked. Release dates place the AMD part in February 2025 and the Intel part in December 2024.

Where Each One Wins

The Intel Core Ultra 5 225T wins in every recorded benchmark category. The AMD Ryzen 3 5305G has no benchmark victories in the database. This does not mean the AMD part lacks utility, but the data shows a clear performance gap.

The Intel part excels in multi-threaded workloads due to its 10 physical cores. Single-core performance also favors the Intel part, which reaches a boost clock of 4.90 GHz compared to 4.20 GHz on the AMD side. The Intel part's higher memory bandwidth and larger cache further support memory-intensive tasks.

The AMD Ryzen 3 5305G offers advantages outside raw benchmark scores. Its unlocked multiplier allows manual overclocking, and its AM4 socket is a mature platform. The 65 W TDP matches the Intel part, so power consumption is not a differentiator. The AMD part's smaller die size of 180 mm² versus 243 mm² for Intel indicates a more compact implementation.

For users requiring high core counts, the Intel part is the clear choice. For users who prioritize platform familiarity and overclocking flexibility, the AMD part remains viable. The benchmark data, however, consistently favors the Intel Core Ultra 5 225T across all tested workloads.

Head-to-Head Benchmarks

The database records 16 benchmark scores for the Intel Core Ultra 5 225T and none for the AMD Ryzen 3 5305G. The head-to-head comparison therefore relies entirely on Intel's recorded results. The AMD part's average benchmark score is 0, while the Intel part averages 30,468 points.

In Cinebench R23 multi-core, the Intel Core Ultra 5 225T scores 21,971. Single-core in the same test reaches 3,101. These are the highest recorded scores in the Intel part's benchmark set. The multi-core result reflects the 10-core design, while the single-core result reflects the 4.90 GHz boost clock.

Cinebench R20 results show 9,227 for multi-core and 1,302 for single-core. Cinebench R15 shows 2,214 for multi-core and 312 for single-core. The scaling from R15 to R23 is consistent with the expected workload progression.

PassMark tests cover a range of workloads. The highest score is data compression at 233,998, followed by multithread at 25,358 and random string sorting at 28,774. Floating point math scores 82,751, while integer math scores 59,543. Extended instructions reach 20,083, and data encryption reaches 18,289. Physics scores 2,053, and find prime numbers scores 284. Single-thread performance in PassMark is 4,348.

The nearest rivals to the Intel Core Ultra 5 225T provide context for its performance. The Intel Core i9-11980HK scores 30,422, which is 0.2% lower than the Ultra 5 225T. The AMD Ryzen 5 7640HS scores 30,390, which is 0.3% lower. The Intel Core i5-13600H scores 30,548, which is 0.3% higher. The AMD Ryzen 7 7736U scores 30,364, which is 0.3% lower. These deltas place the Ultra 5 225T in a tight competitive cluster with these mobile and high-end desktop parts.

The 82nd percentile ranking confirms that the Intel part outperforms most CPUs in the database. The 50th percentile for the AMD part indicates a median position. The gap in average benchmark score, 30,468 versus 0, is stark, but the absence of AMD benchmark data means this comparison is incomplete.

The Verdict

The Intel Core Ultra 5 225T is the superior processor according to all recorded benchmark data. It holds the 82nd percentile ranking, delivers a 4.90 GHz boost clock, and provides 10 physical cores. Its DDR5 memory support doubles the bandwidth of the AMD part. The benchmark results show strong performance across Cinebench and PassMark workloads, with the nearest rivals within 0.3% of its average score.

The AMD Ryzen 3 5305G occupies the 50th percentile and has no recorded benchmarks. Its 4 cores and 8 threads are substantially fewer than the Intel part's 10 cores. The lower base clock of 4.00 GHz and boost clock of 4.20 GHz further disadvantage it in single-threaded tasks. The DDR4 memory support and PCIe Gen 3 connectivity are older standards.

The Intel part's strengths are consistent across all categories. It wins on core count, cache size, memory bandwidth, PCIe generation, process node, and transistor count. The only area where the AMD part offers a clear advantage is the unlocked multiplier, which the Intel part lacks.

For workloads that benefit from multiple cores, the Intel Core Ultra 5 225T is the definitive choice. For single-threaded applications, the higher boost clock also favors Intel. The AMD part's only practical appeal is its overclocking capability on the AM4 platform, but no benchmark data supports a performance advantage from this feature.

The data shows no scenario where the AMD Ryzen 3 5305G outperforms the Intel Core Ultra 5 225T. Users seeking maximum performance from these two options should select the Intel part. Users who require an unlocked multiplier and prefer the AM4 platform may still consider the AMD part, but they should expect lower performance in every recorded benchmark category.
