AMD Ryzen 3 8300G vs Intel Core i5-1334U Comparison

The AMD Ryzen 3 8300G and Intel Core i5-1334U are closely matched overall, with average benchmark scores of 18169 and 18154, respectively, a difference of just 0.1% in favor of the AMD part. Both CPUs sit at the 72nd percentile among all processors, yet their performance profiles are sharply divergent. The Ryzen 3 8300G wins 11 of the 17 head-to-head benchmarks, while the Core i5-1334U takes 6, but the Intel chip’s victories are often by large margins in specific workloads. This is not a story of a single dominant part; it is a story of two architectures optimized for different tasks.

Head-to-Head Benchmarks

The most decisive result is in Cinebench R23 multicore, where the AMD Ryzen 3 8300G scores 12217 against the Intel Core i5-1334U’s 8641, a 41.4% advantage. That is the single largest delta in the entire comparison. A similar pattern appears in PassMark extended instructions, where AMD leads 12354 to 8563, a 44.3% gap. These two results indicate that for heavily threaded, instruction-dense workloads, the Ryzen 3 8300G is in a different class.

The Intel part fights back hardest in floating-point math, scoring 34474 versus AMD’s 25336, a 26.5% lead. It also wins integer math by 19.5%, with scores of 50374 and 40534. These are substantial margins in the PassMark math suite. In Cinebench R15, the Core i5-1334U is also ahead: 1569 to 1231 in multicore (21.5% lead) and 241 to 173 in singlecore (28.2% lead). The Intel chip’s 12 threads versus AMD’s 8 threads likely help in R15’s aging workload, though the gap narrows or reverses in newer Cinebench versions.

The single-core story is inconsistent. In Cinebench R23 singlecore, the Intel part edges ahead by just 0.2%, scoring 1727 against 1724. But in Cinebench R20 singlecore, AMD wins by 10.7% (724 to 654), and in PassMark single-thread, AMD leads by 12.9% (3778 to 3345). The Ryzen 3 8300G’s higher boost clock of 4.90 GHz versus 4.60 GHz for the Intel part contributes to these wins, though the R15 singlecore result (Intel 241 vs AMD 173) contradicts that trend, suggesting the older benchmark does not scale the same way.

In mixed workloads, the AMD chip is consistently ahead. PassMark multithread shows AMD winning 14018 to 13410 (4.5%), and PassMark physics has AMD at 755 versus 722 (4.6%). Random string sorting goes to AMD by 12.3% (19013 to 16933), and data compression by 5.6% (158952 to 150568). The only Intel wins in the PassMark suite beyond math are data encryption, where Intel leads 9377 to 9115 (2.8%), and the two math tests already noted.

Where Each One Wins

The AMD Ryzen 3 8300G dominates in modern multi-threaded rendering and instruction-heavy tasks. Its 41.4% lead in Cinebench R23 multicore is the clearest signal: for video encoding, 3D rendering, or any workload that scales with newer instruction sets, this chip is the pick. The 44.3% win in extended instructions reinforces that point, as does the 20.5% lead in prime number finding (47 to 39). The AMD part also wins all three PassMark memory-related or sorting tasks (compression, random string sorting, multithread), meaning it handles data movement and general-purpose threading better.

The Intel Core i5-1334U is the choice for math-heavy floating-point and integer calculations. Its 26.5% lead in floating-point math and 19.5% lead in integer math are the strongest arguments for this chip. The R15 results, where Intel wins both singlecore (28.2%) and multicore (21.5%), suggest it also does better on legacy software that has not been updated for newer CPU architectures. The 2.8% win in data encryption is minor but shows a slight edge in cryptographic workloads.

For single-threaded performance, the data is split. AMD wins the more modern Cinebench R20 and PassMark tests by roughly 10-13%, while Intel wins the older Cinebench R15 by 28.2%. The R23 singlecore result is a virtual tie (Intel by 0.2%). If the workload relies on modern single-thread performance, the AMD chip is faster; if it relies on older benchmark behavior, the Intel chip wins.

Architecture Differences

The two CPUs are built on fundamentally different designs. The AMD Ryzen 3 8300G uses the Zen 4 architecture on a 4 nm TSMC process, with a die size of 137 mm² and 20,900 million transistors. It has 4 cores and 8 threads, with a base clock of 3.40 GHz and boost of 4.90 GHz. The Intel Core i5-1334U uses Raptor Lake architecture on Intel’s 10 nm process, with 10 cores and 12 threads, a base clock of 1300.00 MHz (1.3 GHz) and boost of 4.60 GHz. The core count difference is stark: Intel offers 10 physical cores versus AMD’s 4, but AMD’s higher clocks and newer process node compensate in many tests.

Cache configurations differ notably. AMD provides 64 KB L1 per core, 1 MB L2 per core, and 8 MB shared L3. Intel provides 80 KB L1 per core, 1.25 MB L2 per core, and 12 MB shared L3. Intel’s larger L3 cache (12 MB vs 8 MB) and larger per-core L1/L2 could explain its wins in math and encryption, where data fits in cache. AMD’s smaller cache but higher clocks and IPC from Zen 4 likely drive its wins in newer Cinebench and PassMark tests.

Memory support is another divergence. AMD supports only DDR5, dual-channel, with 83.2 GB/s bandwidth and ECC memory. Intel supports both DDR4 and DDR5, dual-channel, with no listed bandwidth and no ECC. The AMD part also has more PCIe lanes: 14 lanes of Gen 4 versus Intel’s 8 lanes of Gen 4. This makes the AMD chip more capable for expansion in a desktop context, while the Intel chip’s BGA 1744 socket and 15W TDP mark it as a mobile part. AMD’s TDP is 65W, reflecting its desktop segment, while Intel’s 15W is typical for ultrabooks.

Integrated graphics differ as well: AMD uses Radeon 740M, Intel uses Iris Xe Graphics 80EU. The AMD part is on the AM5 socket with a launch MSRP of $176, while the Intel part is on BGA 1744 with a launch MSRP of $340. Production status is Active for both, but release dates differ: AMD launched on 2024-01-07, Intel on 2023-01-03.

The Verdict

For users running modern multi-threaded applications like Cinebench R23, video encoding, or any workload that benefits from extended instructions, the AMD Ryzen 3 8300G is the clear choice. Its 41.4% lead in R23 multicore and 44.3% lead in extended instructions are decisive. It also wins the majority of PassMark tests, including multithread, physics, compression, and sorting. The higher boost clock of 4.90 GHz and 4 nm Zen 4 architecture deliver better performance in most current software.

For users working with math-heavy calculations, legacy software, or integer/floating-point workloads, the Intel Core i5-1334U is the better option. Its 26.5% lead in floating-point math and 19.5% lead in integer math are substantial. The R15 wins (21.5% multicore, 28.2% singlecore) indicate it handles older code better. The Intel chip also offers 10 cores versus 4, which may appeal to users who prioritize core count on paper, though the benchmark data shows AMD wins most multi-threaded tests anyway.

The overall average scores are nearly tied (18169 vs 18154), and both sit at the 72nd percentile. The decision comes down to workload. The AMD part is a desktop chip with higher power draw (65W vs 15W) and better memory bandwidth (83.2 GB/s vs none listed), while the Intel part is a mobile chip with much lower TDP. If the system is a desktop with room for a 65W processor and DDR5 memory, the Ryzen 3 8300G offers better modern performance. If the system is a laptop or requires the efficiency of a 15W part with support for both DDR4 and DDR5, the Core i5-1334U is the practical choice despite its lower benchmark wins in most categories.
