AMD Ryzen 3 3100U vs Intel Core 9 273PTE Comparison

The AMD Ryzen 3 3100U is a 2-core, 2-thread mobile processor built for efficiency, while the Intel Core 9 273PTE is a 12-core, 24-thread desktop processor built for maximum throughput. Benchmark results show the Intel part wins every recorded head-to-head test, with the largest gaps in heavily parallel workloads. The Ryzen 3 3100U sits at the 62nd percentile of all CPUs in the database, while the Core 9 273PTE reaches the 82nd percentile. The average benchmark score for the AMD chip is 6247, compared to 31143 for the Intel chip. The data indicates the Core 9 273PTE is in a different performance class entirely, suited for demanding desktop tasks, whereas the Ryzen 3 3100U is appropriate for lightweight mobile computing where power draw is the priority.

The Verdict

The Intel Core 9 273PTE is the clear choice for anyone running multi-threaded desktop workloads such as video encoding, 3D rendering, or software compilation. Its 12 cores and 24 threads deliver a PassMark multi-thread score of 24054, which is roughly 7 times the Ryzen 3 3100U's score of 3348. The Intel processor also shows a substantial lead in single-thread performance, scoring 3433 in PassMark single-thread versus 1592 for the AMD chip, a delta of -53.6% from the AMD perspective. For desktop users who need raw compute power, the Core 9 273PTE is the only rational pick from these two.

The AMD Ryzen 3 3100U, by contrast, is a fit for thin-and-light laptops where low power consumption and modest performance are acceptable. Its 15-watt TDP and 2-core configuration produce a much smaller thermal footprint than the Intel part's 45-watt TDP. The Ryzen 3 3100U's PassMark physics score of 232 and floating point math score of 5854 indicate it can handle basic productivity and light media playback. However, the data shows it is not competitive in any measured benchmark against the Core 9 273PTE. The choice between these two is less about preference and more about platform: the Ryzen 3 3100U belongs in a mobile chassis, the Core 9 273PTE belongs on a desktop motherboard.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen 3 3100U uses a 12 nm process at GlobalFoundries, while the Intel Core 9 273PTE uses a 10 nm process at Intel. The AMD chip is based on the Zen+ (Picasso) architecture and belongs to the Ryzen 3 generation. The Intel part uses the Bartlett Lake architecture and belongs to the Core 9 generation. The transistor count for the AMD chip is 4,940 million on a 210 mm² die; the Intel chip's transistor count and die size are not recorded in the database.

Core and thread counts diverge sharply. The Ryzen 3 3100U has 2 cores and 2 threads, meaning no simultaneous multithreading. The Core 9 273PTE has 12 cores and 24 threads, giving it 6 times the core count and 12 times the thread count. Cache hierarchies also differ: the AMD chip provides 96 KB L1 per core, 512 KB L2 per core, and 4 MB shared L3. The Intel chip provides 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The larger L3 cache on the Intel part supports its higher core count and more demanding workloads.

Memory support splits the two as well. The Ryzen 3 3100U supports DDR4 only, while the Core 9 273PTE supports both DDR4 and DDR5. Memory bandwidth is 38.4 GB/s for the AMD part versus 89.6 GB/s for the Intel part. The Intel chip also supports ECC memory, which the AMD chip does not. PCIe generation differs: the AMD processor uses Gen 3, while the Intel processor uses Gen 5 with 16 CPU lanes. Integrated graphics are present on both, with the AMD chip using Radeon Vega 8 and the Intel chip using UHD Graphics 730. The AMD part uses AMD Socket FP5, and the Intel part uses Intel Socket 1700. The Intel chip's launch MSRP is $549.

Head-to-Head Benchmarks

The Intel Core 9 273PTE wins all 11 recorded head-to-head benchmarks. The smallest relative gap appears in single-thread tests. PassMark single-thread scores are 1592 for the AMD chip and 3433 for the Intel chip, a delta of -53.6% from the AMD perspective. The same pattern appears in the duplicate PassMark singlethread test with identical scores. This indicates the Intel core architecture holds a significant per-thread advantage, not just a core-count advantage.

The largest gaps appear in floating point math and integer math. In PassMark floating point math, the AMD chip scores 5854 against the Intel chip's 60673, a delta of -90.4%. In PassMark integer math, the AMD chip scores 8873 against 82411, a delta of -89.2%. These results point to the Intel processor being roughly an order of magnitude faster in heavy arithmetic workloads, which is consistent with its 12-core, 24-thread configuration and higher boost clock of 5.50 GHz versus the AMD chip's 3.20 GHz boost.

Data compression and encryption also show large deltas. The AMD chip scores 38455 in PassMark data compression versus 258704 for the Intel chip, a delta of -85.1%. In data encryption, the AMD chip scores 1972 versus 14253, a delta of -86.2%. The extended instructions test shows 2116 for the AMD chip and 15952 for the Intel chip, a delta of -86.7%. Prime number finding reports 18 for the AMD chip and 142 for the Intel chip, a delta of -87.3%. Random string sorting shows 4666 for the AMD chip and 28973 for the Intel chip, a delta of -83.9%. The physics test shows 232 for the AMD chip and 1917 for the Intel chip, a delta of -87.9%. In every case, the Intel processor's advantage exceeds 80%, with the single-thread tests being the only ones below that threshold.

Where Each One Wins

The Intel Core 9 273PTE wins every recorded benchmark category. Its strengths are most pronounced in multi-threaded and math-heavy tasks. The PassMark floating point math score of 60673 and integer math score of 82411 show a processor capable of sustained heavy computation. The PassMark multithread score of 24054 and data compression score of 258704 further confirm its suitability for parallel workloads. The Cinebench R23 multicore score of 20445 and R20 multicore score of 8586 reinforce this pattern for rendering applications. The physics score of 1917 indicates strong performance in simulation and game physics calculations. The Intel chip's single-thread score of 3433 also makes it competitive in lightly threaded applications, though its advantage there is smaller relative to its multi-thread lead.

The AMD Ryzen 3 3100U does not win any recorded benchmark. Its only practical advantage comes from its 15-watt TDP, which is one-third of the Intel chip's 45-watt TDP. This makes it suitable for battery-powered mobile devices where heat and power draw are limiting factors. Its integrated Radeon Vega 8 graphics and 2-core design are adequate for basic productivity, web browsing, and media consumption. The PassMark single-thread score of 1592 is low but workable for everyday tasks. The Ryzen 3 3100U's 62nd percentile ranking places it below the Intel chip's 82nd percentile, but its low power envelope is the deciding factor for laptop integration. Neither processor is a general-purpose substitute for the other given their different sockets and market segments.
