Architecture Differences

The AMD Ryzen 3 5305G belongs to the 5000 series, codenamed Cezanne, built on the Zen 3 architecture. It is manufactured on a 7 nm process at TSMC, with a transistor count of 10,700 million and a die size of 180 mm². The Intel Core 9 273PTE comes from the Bartlett Lake codename, fabricated on Intel's 10 nm process. The database records no transistor count or die size for the Intel chip, which limits direct physical comparison, but the architectural split is clear: Zen 3 versus Bartlett Lake.

The AMD chip uses the AMD Socket AM4, while the Intel chip uses Intel Socket 1700. The AMD processor has an unlocked multiplier, enabling overclocking, whereas the Intel processor has a locked multiplier. The AMD part is listed as a Ryzen 3 generation part, and the Intel part is listed as a Core 9 generation part.

Cache hierarchies differ substantially. 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 9 273PTE has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The Intel chip offers 4.5 times the L3 capacity, which benefits workloads that repeatedly access large data sets.

Memory support also separates the two. The AMD chip supports DDR4 in a dual-channel configuration, delivering 51.2 GB/s of bandwidth. The Intel chip supports both DDR4 and DDR5 in dual-channel mode, with 89.6 GB/s of bandwidth. The Intel part also enables ECC memory, a feature absent on the AMD side. PCIe connectivity differs as well: the AMD chip provides Gen 3 with 16 lanes, while the Intel chip provides Gen 5 with 16 lanes.

Where Each One Wins

The Intel Core 9 273PTE dominates in multi-threaded workloads. Its 12 cores and 24 threads, combined with 36 MB of shared L3 cache and a 5.50 GHz boost clock, make it the stronger choice for rendering, compilation, scientific computation, and other parallel tasks. The recorded Cinebench multi-core scores reflect this: the Intel chip scores 20445 in Cinebench R23 multi-core, a massive margin over what the 4-core AMD part could produce in the same test.

The AMD Ryzen 3 5305G does not have recorded benchmark scores in the database, so direct numerical comparisons must rely on the Intel chip's data alone. However, the AMD chip's high base clock of 4.00 GHz and boost of 4.20 GHz, combined with 4 cores and 8 threads, position it as a lower-power desktop part for lighter duties. Its 65 W TDP, compared to the Intel chip's 45 W TDP, indicates a different power envelope, with the Intel part drawing less power despite having more cores.

Single-thread performance favors the Intel chip on paper. The Intel boost clock of 5.50 GHz is 1.30 GHz higher than the AMD boost clock, and the Cinebench R23 single-core score of 2886 confirms strong single-thread capability. For workloads that rely on a single core, such as older games or lightly threaded applications, the Intel processor should hold an edge. For multi-threaded productivity, the Intel part is clearly the better fit, while the AMD part suits systems where a modest 4-core desktop chip with integrated Radeon Vega 6 graphics is sufficient.

Specification Differences

The two processors differ across several core specification fields. The AMD Ryzen 3 5305G has 4 cores and 8 threads, while the Intel Core 9 273PTE has 12 cores and 24 threads. Base clocks are 4.00 GHz for AMD and 1.40 GHz for Intel. Boost clocks are 4.20 GHz for AMD and 5.50 GHz for Intel. TDP values are 65 W for AMD and 45 W for Intel.

Sockets differ: AMD Socket AM4 versus Intel Socket 1700. The AMD chip uses the Zen 3 architecture with the Cezanne codename, while the Intel chip uses the Bartlett Lake codename with no architecture field recorded. Process nodes are 7 nm (TSMC) for AMD and 10 nm (Intel) for Intel. The AMD part has a known transistor count of 10,700 million and die size of 180 mm², while the Intel part has no recorded values for either.

Cache layouts differ: the AMD chip has 64 KB L1 per core, 512 KB L2 per core, and 8 MB L3. The Intel chip has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3.

PCIe is Gen 3 with 16 lanes on AMD, versus Gen 5 with 16 lanes on Intel.

Integrated graphics differ: Radeon Vega 6 on AMD, UHD Graphics 730 on Intel. The AMD multiplier is unlocked, the Intel multiplier is locked. The Intel part has a launch MSRP of $549. The AMD part has no recorded launch MSRP. Release dates also differ: the AMD chip was released on 2025-02-23, and the Intel chip on 2026-03-08. Market segment is Desktop for both, and production status is Active for both.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Ryzen 3 5305G and the Intel Core 9 273PTE, and the AMD chip has no individual benchmark scores recorded. The Intel Core 9 273PTE, however, has a full set of Cinebench and PassMark results, along with a percentile ranking and rival comparisons.

The Intel Core 9 273PTE scores 20445 in Cinebench R23 multi-core and 2886 in Cinebench R23 single-core. In Cinebench R20, it scores 8586 multi-core and 1212 single-core. In Cinebench R15, it scores 2060 multi-core and 290 single-core. These results show a processor with strong scaling from R15 to R23, consistent with a 12-core, 24-thread design.

PassMark results for the Intel chip are extensive. It scores 258704 in data compression, 14253 in data encryption, 15952 in extended instructions, 142 in find prime numbers, 60673 in floating point math, 82411 in integer math, 24054 in multithread, 1917 in physics, 28973 in random string sorting, and 3433 in single thread. The multithread score of 24054 versus the single-thread score of 3433 indicates a roughly 7x scaling factor, which aligns with the core and thread counts.

The Intel chip's average benchmark score is 31143, placing it at the 82nd percentile of all CPUs in the database. Its nearest rivals are the Intel Core i7-12700F with an average score of 31081 and a delta of 0.2 percent, the AMD Ryzen 9 8945HS with 31074 and a delta of 0.2 percent, the Intel Core i7-13700TE with 31028 and a delta of 0.4 percent, and the Intel Core i7-12650HX with 31290 and a delta of -0.5 percent. This means the Core 9 273PTE sits within half a percent of four comparable processors, essentially tied with the Intel Core i7-12650HX and marginally ahead of the other three.

Since the AMD Ryzen 3 5305G has no benchmark scores in the database, the comparison is incomplete from a measurement standpoint. The AMD chip's 50th percentile ranking, with an average benchmark score of zero, reflects the absence of recorded tests rather than actual performance. The Intel chip's 82nd percentile ranking, by contrast, is backed by 17 recorded benchmark scores. The data confirms that the Intel Core 9 273PTE is a high-performing desktop processor, while the AMD Ryzen 3 5305G remains a lower-tier entry in the 5000 series with no measured results to analyze.
