AMD Ryzen 3 8300G vs Intel Core 5 221E Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive outcome: the Intel Core 5 221E wins all 17 recorded head-to-head comparisons against the AMD Ryzen 3 8300G. There are no wins for the AMD part in any of the measured tests. The margins are substantial across the board, though they vary considerably depending on workload type.

The largest gap appears in PassMark's find prime numbers test, where the Intel part scores 173 against the AMD's 47, a delta of -72.8% from the AMD's perspective. This indicates a massive advantage in integer-heavy, single-threaded mathematical workloads. Similarly large deltas appear in floating point math, where the Intel scores 79028 versus 25336, a -67.9% difference, and in physics, where the Intel reaches 2230 against 755, a -66.1% gap. Integer math also shows a wide separation: 117813 versus 40534, or -65.6%.

Cinebench results are remarkably consistent in their margins. All six Cinebench tests, both single-core and multi-core across R15, R20, and R23, show the Intel part ahead by 52.9% or 53.0%. For instance, in Cinebench R23 multi-core, the Intel Core 5 221E scores 25933 while the Ryzen 3 8300G scores 12217. In Cinebench R23 single-core, the scores are 3661 versus 1724. This uniformity suggests the performance gap is structural, not workload-specific, within rendering tasks.

The narrowest margin is in PassMark single-thread performance. Here the Intel part scores 4147 versus the AMD's 3778, a delta of only -8.9%. This is the only test where the AMD processor comes close to parity. It indicates that while the Intel chip has a strong single-core advantage, that advantage is much smaller than the multi-core gaps seen elsewhere.

Data compression shows a -51.0% delta, with the Intel scoring 324285 against 158952. Data encryption shows a -52.5% delta, with scores of 19205 versus 9115. Extended instructions show a -32.2% delta, the second-smallest margin after single-thread, with the Intel at 18216 versus 12354. Random string sorting completes the picture at -49.5%, with scores of 37686 versus 19013.

The aggregate benchmark scores confirm the scale of the victory. The Intel Core 5 221E has an average benchmark score of 40144 and sits at the 87th percentile among all CPUs. The AMD Ryzen 3 8300G has an average score of 18169 and sits at the 72nd percentile. The Intel part's nearest rivals in the database include the AMD Ryzen 7 7700 at 40081, the AMD Ryzen AI 9 365 at 40048, the AMD Ryzen 9 270 at 40246, and the Intel Core i9-13905H at 40313. The AMD part's nearest rivals include the AMD Ryzen 7 5700U at 18176, the Intel Core i7-1365U at 18177, the Intel Core i7-9700 at 18180, and the Intel Core i5-1334U at 18154.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen 3 8300G uses TSMC's 4 nm process and is built on the Zen 4 architecture with the codename Phoenix2. It belongs to the 8000 series and the Ryzen 3 generation. The Intel Core 5 221E uses Intel's 10 nm process and carries the codename Bartlett Lake, belonging to the Core 5 generation. The AMD die measures 137 mm² with 20,900 million transistors, while the Intel die measures 257 mm² with no transistor count recorded in the database.

Core and thread counts differ significantly. The AMD part has 4 cores and 8 threads, while the Intel part has 14 cores and 20 threads. This explains much of the multi-core performance gap. The Intel part also has a higher boost clock at 5.20 GHz versus 4.90 GHz for the AMD, though the AMD has a higher base clock at 3.40 GHz versus 2.70 GHz.

Cache configurations follow different designs. The AMD chip 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 has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The larger L3 cache on the Intel part is three times the size of the AMD's.

Memory support differs in an important way. The AMD Ryzen 3 8300G supports DDR5 only, while the Intel Core 5 221E supports both DDR4 and DDR5. Both use dual-channel memory buses. The Intel part has a higher memory bandwidth at 89.6 GB/s versus 83.2 GB/s for the AMD. Both support ECC memory.

PCIe connectivity also differs. The AMD part provides Gen 4 with 14 lanes from the CPU, while the Intel part provides Gen 5 with 16 lanes. The Intel part therefore offers both a newer PCIe generation and more lanes.

Integrated graphics differ by vendor. The AMD part uses the Radeon 740M, while the Intel part uses UHD Graphics 730. Both processors are desktop parts with a 65 W TDP. Both are currently in active production. Neither has an unlocked multiplier. The AMD part uses AMD Socket AM5, while the Intel part uses Intel Socket 1700.

Release dates are roughly a year apart. The AMD Ryzen 3 8300G was released on 2024-01-07, while the Intel Core 5 221E was released on 2025-01-12. The AMD launch MSRP is $176, and the Intel launch MSRP is $232.

The Verdict

The recorded data is unambiguous. The Intel Core 5 221E outperforms the AMD Ryzen 3 8300G in every single benchmark test in the database. The AMD part does not win a single comparison. The average benchmark score for the Intel part is 40144, more than double the AMD's 18169. The percentile ranking also reflects this: 87th versus 72nd.

The Intel part's advantages are largest in workloads that scale with core count and cache size. The 14-core, 20-thread configuration with 24 MB of L3 cache delivers multi-core Cinebench scores that are roughly double the AMD's, and PassMark multi-thread scores that are more than double. The 5.20 GHz boost clock helps keep single-core performance ahead as well, though by a much smaller margin.

The AMD Ryzen 3 8300G does have some advantages in the specification data. Its 4 nm TSMC process is more advanced than Intel's 10 nm node, and its base clock is higher at 3.40 GHz. It also has a lower launch MSRP at $176 versus $232. However, the benchmark data does not show any workload where these advantages translate into a measured performance win.

For buyers choosing between these two based strictly on the recorded measurements, the Intel Core 5 221E is the stronger processor in every tested category. The scale of the multi-core advantage, combined with the single-core lead, leaves no benchmark-based reason to select the AMD part for performance purposes.

Where Each One Wins

The Intel Core 5 221E wins in every benchmark category recorded. The largest margins are in find prime numbers at -72.8%, floating point math at -67.9%, physics at -66.1%, and integer math at -65.6%. These are compute-heavy workloads where the Intel part's 14 cores, 20 threads, and 24 MB L3 cache provide a decisive advantage.

The Intel part also wins all rendering workloads. Cinebench R15, R20, and R23 both single-core and multi-core all show deltas of -52.9% or -53.0%. This consistency across rendering generations indicates a fundamental performance advantage rather than a test-specific artifact.

Data compression and encryption workloads also favor the Intel part. Data compression shows a -51.0% delta, and data encryption shows a -52.5% delta. Extended instructions show the second-smallest margin at -32.2%, while random string sorting shows -49.5%.

The AMD Ryzen 3 8300G does not win any recorded benchmark. Its closest performance to the Intel part is in PassMark single-thread, where the delta is only -8.9%. This indicates the AMD chip is competitive in lightly threaded scenarios, but even there it trails.

The AMD part's advantages are limited to specifications rather than measured performance. It has a higher base clock at 3.40 GHz versus 2.70 GHz, a more advanced 4 nm process node versus 10 nm, and a lower launch MSRP at $176 versus $232. It also uses AMD Socket AM5 rather than Intel Socket 1700. None of these translate into a benchmark win in the recorded data.
