Architecture Differences

The AMD Ryzen 5 5605G is built on the Zen 3 architecture with the codename Cezanne, part of the 5000 series. It uses a 7 nm process node from TSMC and contains 10,700 million transistors on a 180 mm² die. The Intel Core 3 305 uses a 3 nm process node fabricated by Intel, with the codename Wildcat Lake. The Intel die size and transistor count are not recorded in the database.

Cache layouts differ substantially. The AMD processor provides 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of shared L3 cache. The Intel processor records 192 KB of L1 cache total, 2.5 MB of L2 cache total, and 6 MB of shared L3 cache. The AMD chip's larger L3 pool is consistent with its desktop-oriented Zen 3 design.

The AMD Ryzen 5 5605G uses AMD Socket AM4 and supports PCIe Gen 3 with 16 CPU lanes. The Intel Core 3 305 uses Intel BGA 1516 and supports PCIe Gen 4 with 6 CPU lanes. The Intel part is a mobile segment chip, while the AMD part targets desktops.

Integrated graphics also differ. The AMD chip uses Radeon Vega 7 graphics, while the Intel chip uses Intel Xe3 Graphics with one Xe core. The AMD processor has an unlocked multiplier, while the Intel processor does not. The AMD chip is also not listed with ECC memory support, and neither is the Intel part.

Head-to-Head Benchmarks

The database contains benchmark results only for the Intel Core 3 305. The AMD Ryzen 5 5605G has no recorded benchmark scores, and the head-to-head benchmark array is empty. As a result, direct comparisons rely on the Intel part's absolute scores and its position relative to nearby rivals.

The Intel Core 3 305 delivers a Cinebench R23 multi-core score of 13123 and a single-core score of 1852. In Cinebench R20, it scores 5511 multi-core and 777 single-core. The Cinebench R15 results are 1322 multi-core and 186 single-core. These scores place the chip at the 72nd percentile overall.

PassMark results for the Intel Core 3 305 show a multi-thread score of 15439 and a single-thread score of 3977. Integer math scores 32295, floating point math scores 42284, and extended instructions score 13543. Data compression scores 146857, data encryption scores 11019, and random string sorting scores 17623. Physics scores 1233, and finding prime numbers scores 115.

The nearest rivals in the database provide context for the Intel part's performance. The Intel Core i3-14100 has an average score of 18318, which is 0.1% higher than the Core 3 305's 18302. The Intel Core 5 330 scores 18345, 0.2% higher. The Intel Core 7 360 scores 18374, 0.4% higher. On the other side, the AMD Ryzen 5 2600E scores 18230, which is 0.4% lower. This cluster of results places the Core 3 305 within a narrow performance band, where the largest recorded delta among these rivals is just 0.4%.

Because the AMD Ryzen 5 5605G has no recorded average score, the data cannot confirm whether it would outperform or trail the Intel part in any specific test. The percentile gap is visible, however: 50th percentile for the AMD versus 72nd percentile for the Intel. The absence of AMD benchmark data limits any head-to-head numeric analysis to the Intel side only.

The Verdict

The recorded data shows two processors aimed at different market segments. The AMD Ryzen 5 5605G is a desktop chip with a 65 W TDP, 12 threads, a 3.90 GHz base clock, and DDR4 support. The Intel Core 3 305 is a mobile chip with a 15 W TDP, 6 threads, a 1.50 GHz base clock, and DDR5/LPDDR5X support.

Benchmark data exists only for the Intel Core 3 305. Its average score of 18302 places it at the 72nd percentile, and its nearest rivals are separated by no more than 0.4%. The AMD Ryzen 5 5605G sits at the 50th percentile with no recorded average score. The data cannot justify a direct performance claim for the AMD part in any test.

The Intel part's single-channel memory bus is notable given its 59.7 GB/s bandwidth figure, which is higher than the AMD part's 51.2 GB/s despite the AMD chip using dual-channel memory. The Intel chip also uses PCIe Gen 4, though with only 6 lanes compared to the AMD chip's 16 PCIe Gen 3 lanes.

For users selecting based on recorded measurements, the Intel Core 3 305 has the only available benchmark profile. Its scores cluster tightly with the Intel Core i3-14100, Intel Core 5 330, Intel Core 7 360, and AMD Ryzen 5 2600E. The AMD Ryzen 5 5605G offers more threads, a higher base clock, a larger L3 cache, and an unlocked multiplier, but none of those features are backed by benchmark scores in the database.

Where Each One Wins

The Intel Core 3 305 wins in every category where numerical data exists. It has the only recorded benchmark scores, the higher percentile ranking (72 versus 50), a higher memory bandwidth figure (59.7 GB/s versus 51.2 GB/s), a newer process node (3 nm versus 7 nm), and PCIe Gen 4 support. Its 15 W TDP also indicates a much lower power envelope than the AMD part's 65 W TDP, which suits mobile applications.

The AMD Ryzen 5 5605G wins on structural specifications. It provides 12 threads versus 6, a 3.90 GHz base clock versus 1.50 GHz, a slightly higher boost clock (4.40 GHz versus 4.30 GHz), a larger L3 cache (16 MB versus 6 MB), dual-channel memory support, 16 PCIe Gen 3 lanes versus 6 PCIe Gen 4 lanes, and an unlocked multiplier. Its DDR4 support may also align with existing desktop platforms on Socket AM4.

The use-case split follows the market segment labels. The Intel Core 3 305 is a mobile processor with benchmark evidence of competitive performance near the Intel Core i3-14100. The AMD Ryzen 5 5605G is a desktop processor whose strengths are recorded in its specifications rather than its test scores. The data supports choosing the Intel part when measured performance and portability matter, and the AMD part when thread count, desktop socket compatibility, and overclocking support matter.
