AMD Ryzen 3 PRO 5355G vs Intel Core 9 273PTE Comparison

The AMD Ryzen 3 PRO 5355G and the Intel Core 9 273PTE occupy very different positions in the desktop processor landscape. The recorded data shows a comprehensive performance gap, with the Intel part winning all 11 head-to-head benchmark comparisons. The Ryzen 3 PRO 5355G is a 4-core, 8-thread Zen 3 chip aimed at efficient mainstream work, while the Core 9 273PTE is a 12-core, 24-thread Bartlett Lake part with a much higher ceiling for multi-threaded tasks. This analysis breaks down the exact benchmark results, architectural differences, and what the numbers mean for specific workloads.

Head-to-Head Benchmarks

The Intel Core 9 273PTE dominates every recorded comparison, but the margin varies significantly by workload type. The largest single deficit for the AMD chip appears in the prime number calculation test, where the Intel part scores 142 versus 36 for the Ryzen, a delta of -74.6%. This is a massive gap that highlights the raw integer throughput advantage of the Intel part's 12 cores and 24 threads.

Floating-point math shows a similar pattern. The Intel scores 60673 against 25245 for the AMD, a -58.4% difference. Physics simulation results are also heavily lopsided: 1917 versus 701, a -63.4% gap. These three tests indicate that the Intel part is far better suited for scientific computing and physics-based simulations, where both core count and memory bandwidth matter.

Integer math performance favors Intel by -44.3%, with scores of 82411 and 45910. This is a substantial lead that will show up in compilation and data processing tasks. The multi-threaded PassMark score, which aggregates overall parallel performance, shows Intel at 24054 versus 14033, a -41.7% difference. This is the broadest measure of all-core throughput and confirms the Intel part is roughly 71% faster in aggregate multi-threading.

The single-thread scores are the closest comparison in the entire dataset. Intel scores 3433, AMD scores 3096, a -9.8% difference. This is the only test where the gap is under 20%, showing that the Zen 3 architecture in the AMD part remains competitive on a per-core basis. The Ryzen 3 PRO 5355G has a base clock of 4.00 GHz and a boost of 4.20 GHz, while the Intel part has a much lower 1.40 GHz base but a 5.50 GHz boost, which explains the single-thread edge.

Data compression results favor Intel by -35%, with scores of 258704 and 168041. Encryption also goes to Intel, 14253 versus 10288, a -27.8% gap. Extended instruction workloads (AVX, SSE) show Intel ahead at 15952 versus 11935, a -25.2% difference. Random string sorting, a test sensitive to cache hierarchy, gives Intel 28973 versus 18819, another -35% margin. In every category, the Intel part is ahead, but the percentage deficits shrink considerably when the workload is more latency-bound than throughput-bound.

Where Each One Wins

The Intel Core 9 273PTE wins every benchmark category in the database. There is no recorded test where the AMD Ryzen 3 PRO 5355G takes a lead. The closest margin is single-thread performance at -9.8%, which means the AMD part is competitive for lightly threaded tasks but still loses. For users running a single application that relies on one or two cores, the Ryzen 3 PRO 5355G will not feel dramatically slower, but it is measurably behind.

The Intel part's biggest advantages are in prime number finding (-74.6%), physics (-63.4%), and floating-point math (-58.4%). These are all heavily parallel workloads that scale with core count and memory bandwidth. The Intel part has 3 times the cores (12 versus 4) and 3 times the threads (24 versus 8), which directly drives these results. The Intel part also has a much larger L3 cache at 36 MB shared versus 8 MB, which helps with data reuse in scientific workloads.

For data compression and encryption, the Intel part is roughly 27-35% ahead. These workloads benefit from both core count and the newer PCIe Gen 5 interface on the Intel side, although the benchmark itself is CPU-bound. The AMD part does hold its own relatively better in extended instructions (-25.2%) and random string sorting (-35%), where the Zen 3 architecture's per-core efficiency narrows the gap. However, no workload category favors the AMD chip.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 3 PRO 5355G is built on the Zen 3 architecture with the Cezanne codename, manufactured on a 7 nm process at TSMC. It has 4 cores and 8 threads, with a base clock of 4.00 GHz and a boost of 4.20 GHz. The Intel Core 9 273PTE uses the Bartlett Lake codename, built on a 10 nm process at Intel, with 12 cores and 24 threads, a base clock of 1.40 GHz and a boost of 5.50 GHz.

The cache layouts are markedly different. The AMD part uses 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of L3. The Intel part uses 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. This gives the Intel part significantly more total cache, which shows in the random string sorting and data compression benchmarks. The AMD part has a total of 10,700 million transistors on a 180 mm² die, while the Intel part has no recorded transistor count or die size.

Memory support differs. The AMD part supports only DDR4 with dual-channel memory and a bandwidth of 51.2 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel, but with a much higher bandwidth of 89.6 GB/s. This 75% bandwidth advantage directly contributes to the Intel part's wins in memory-intensive tests like floating-point math and physics.

The integrated graphics also differ: the AMD part uses Radeon Vega 6, the Intel part uses UHD Graphics 730. The AMD part has a 65 W TDP, while the Intel part has a 45 W TDP, despite the Intel part being far more powerful. The AMD part uses PCIe Gen 3 with 16 CPU lanes, while the Intel part uses PCIe Gen 5 with 16 CPU lanes. Both support ECC memory and both have locked multipliers.

The Verdict

The benchmark data is unambiguous. The Intel Core 9 273PTE outperforms the AMD Ryzen 3 PRO 5355G in every single recorded test, winning all 11 head-to-head comparisons. The average benchmark score for the Intel part is 31143, placing it in the 82nd percentile of all CPUs. The AMD part averages 27382, placing it in the 79th percentile. The Intel part is also surrounded by different rivals: its nearest competitors include the Intel Core i7-12700F and AMD Ryzen 9 8945HS, while the AMD part sits near the Intel Core i7-13700H and AMD Ryzen 7 5800.

The Intel Core 9 273PTE is the clear choice for any workload that uses more than two threads. Its 12 cores and 24 threads deliver 74.6% better prime number performance, 63.4% better physics scores, and 58.4% better floating-point math. It also has 75% higher memory bandwidth and 4.5 times more L3 cache. The 45 W TDP is notable: the Intel part consumes less power than the AMD part while delivering far more performance.

The AMD Ryzen 3 PRO 5355G is not without merit, but its advantages are limited. It uses an older 7 nm process, which is more efficient per clock, and its 4.00 GHz base clock is much higher than the Intel part's 1.40 GHz. The single-thread gap is only 9.8%, meaning the AMD part is serviceable for basic desktop use and lightly threaded applications. Its 65 W TDP and AM4 socket make it a drop-in upgrade for existing AM4 systems, but the data shows it is decisively behind the Intel part in every measurable way. The database records no benchmark where the AMD part wins, so the Intel Core 9 273PTE is the only rational choice for performance-oriented builds.
