AMD Ryzen 3 8300G vs Intel Core i5-13420H Comparison

The Verdict

The benchmark data presents a clear split between these two processors. The Intel Core i5-13420H wins 13 of the 17 recorded head-to-head tests, while the AMD Ryzen 3 8300G wins 4. The Intel part is the stronger choice for multi-threaded workloads, particularly those involving floating-point math, integer math, data encryption, and data compression. The AMD part, however, takes the lead in the two most modern Cinebench versions and in single-threaded PassMark tests. The data suggests that users prioritizing heavy parallel processing and general productivity should select the Intel Core i5-13420H. Users focused on the latest Cinebench rendering workloads or who prioritize raw single-thread performance in the PassMark suite should consider the AMD Ryzen 3 8300G. Both processors sit at the same 72nd percentile against all CPUs in the database, and their average benchmark scores are close: 18511 for Intel versus 18169 for AMD, a difference of less than 2%.

Architecture Differences

The two chips come from fundamentally different design philosophies. The Intel Core i5-13420H is a mobile processor built on Raptor Lake architecture, using a 10 nm process node from Intel's own foundry. It has 8 cores and 12 threads, arranged in a hybrid configuration that includes performance and efficiency cores. The AMD Ryzen 3 8300G is a desktop chip based on Zen 4 architecture, codenamed Phoenix2, manufactured by TSMC on a 4 nm process. It has 4 cores and 8 threads. The AMD part integrates 20,900 million transistors on a 137 mm² die, while the Intel chip has no transistor or die size data recorded.

The cache hierarchies differ significantly. The Intel processor has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 12 MB of shared L3 cache. The AMD processor has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of shared L3 cache. The Intel chip supports both DDR4 and DDR5 memory, while the AMD chip supports only DDR5. The AMD part supports ECC memory, while the Intel does not. The Intel chip offers PCIe Gen 5 with 8 lanes (CPU only), whereas the AMD offers PCIe Gen 4 with 14 lanes (CPU only). The AMD memory bandwidth is recorded at 83.2 GB/s, while no such figure is available for the Intel. The Intel integrated graphics are Iris Xe Graphics 80EU, while the AMD uses Radeon 740M. The Intel part is a mobile component with a 45 W TDP, while the AMD is a desktop part with a 65 W TDP.

Head-to-Head Benchmarks

The most decisive Intel victories come in the PassMark suite. The floating-point math test shows a 69% advantage for the Intel chip, scoring 42806 against 25336 for the AMD. The integer math test shows a 43.5% lead, with scores of 58156 versus 40534. Data compression is 31.8% faster on the Intel, at 209450 versus 158952. Data encryption is 26.8% faster, at 11559 versus 9115. The Intel also wins the multi-thread PassMark test by 24.7%, scoring 17475 against 14018. The physics test shows a 34% lead for Intel, 1012 versus 755. Other Intel wins include prime number finding (10.6%, 52 versus 47), random string sorting (15.9%, 22045 versus 19013), and extended instructions (4.4%, 12897 versus 12354).

In Cinebench, the results are mixed by version. The Intel chip wins the R15 multicore test by 41.2%, with 1738 versus 1231, and the R15 singlecore test by 37.6%, 238 versus 173. The Intel also wins R20 multicore by 17.2%, 6013 versus 5131, and singlecore by 17.1%, 848 versus 724. However, the AMD takes the newer R23 tests. In R23 multicore, the AMD scores 12217 against 11084, which represents a 9.3% advantage for the AMD. In R23 singlecore, the AMD leads 1724 to 1689, a 2% margin. The AMD also wins the PassMark single-thread test, scoring 3778 versus 3396, a 10.1% advantage.

The data shows a pattern: the Intel part dominates in older Cinebench versions and in most PassMark math and data workloads, while the AMD part is faster in R23 and in a pure single-thread PassMark test. The Intel wins the overall head-to-head count 13 to 4, but the AMD's R23 wins are notable because they come in a widely used modern rendering benchmark.

Specification Differences

The two processors differ in nearly every major specification category. The Intel has 8 cores and 12 threads, while the AMD has 4 cores and 8 threads. The Intel base clock is 2.10 GHz, and the boost clock is 4.60 GHz. The AMD base clock is 3.40 GHz, and the boost clock is 4.90 GHz. The Intel TDP is 45 W, the AMD TDP is 65 W. The sockets are not interchangeable: the Intel uses Intel BGA 1744, while the AMD uses AMD Socket AM5. The process nodes differ as noted: 10 nm for Intel versus 4 nm for AMD. The memory support differs: Intel supports DDR4 and DDR5, while AMD supports DDR5 only. The AMD has an ECC memory option, the Intel does not. The PCIe generations differ: Gen 5 for Intel, Gen 4 for AMD, with lane counts of 8 and 14, respectively. The integrated graphics are different models: Iris Xe Graphics 80EU versus Radeon 740M. The release dates are different: the Intel launched on January 3, 2023, and the AMD launched on January 7, 2024. The Intel part number is SRMHX; the AMD part number is 100-000001492. The AMD has a recorded launch MSRP of $176, while the Intel has no launch MSRP recorded. Neither processor has an unlocked multiplier.
