Architecture Differences

The two processors diverge sharply in core count and process technology. The AMD Ryzen 3 8300G is a Zen 4 design, codenamed Phoenix2, built at TSMC on a 4 nm node. It carries 20,900 million transistors on a 137 mm² die. The Intel Core 7 251E, codenamed Bartlett Lake, is manufactured by Intel on a 10 nm node with a die size of 257 mm². The database does not list a transistor count for the Intel part, so no comparison is possible there.

The core configuration explains much of the performance character. The AMD processor has 4 cores and 8 threads, with 64 KB of L1 cache per core, 1 MB of L2 per core, and 8 MB of shared L3. The Intel processor has 24 cores and 32 threads, with 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Intel part offers a much larger cache hierarchy and more than triple the thread count.

Clock speeds follow different strategies. The AMD chip runs at a base of 3.40 GHz and boosts to 4.90 GHz. The Intel chip runs at a lower base of 2.10 GHz but boosts to 5.60 GHz. The higher boost on the Intel processor suggests a design aimed at short bursts of single-thread activity, while the AMD processor maintains a higher base clock for sustained loads.

Memory support also differs. The AMD Ryzen 3 8300G uses DDR5 with a dual-channel bus and a memory bandwidth of 83.2 GB/s. The Intel Core 7 251E supports both DDR4 and DDR5, also dual-channel, with a higher listed memory bandwidth of 89.6 GB/s. Both processors support ECC memory, which is relevant for workstation and server-adjacent workloads.

PCIe connectivity is another differentiator. The AMD processor provides Gen 4 with 14 lanes from the CPU. The Intel processor provides Gen 5 with 16 lanes from the CPU. The Intel part has a more current PCIe generation and more lanes, which can matter for storage and expansion cards.

Integrated graphics also differ. The AMD Ryzen 3 8300G uses Radeon 740M graphics, while the Intel Core 7 251E uses UHD Graphics 770. The database does not include graphics benchmarks, so no performance comparison is possible.

Socket compatibility is distinct. The AMD processor uses AMD Socket AM5, while the Intel processor uses Intel Socket 1700. The AMD part is from the 8000 series and belongs to the Ryzen 3 generation under Zen 4 (Phoenix). The Intel part belongs to the Core 7 generation under Bartlett Lake.

Release dates differ by about a year. The AMD processor has a release date of January 7, 2024, while the Intel processor has a release date of January 12, 2025. Both are listed as active production parts. Neither has an unlocked multiplier.

Head-to-Head Benchmarks

The database does not contain any head-to-head benchmark entries for these two processors. The headToHeadBenchmarks field is empty, and the win counts for both sides are zero. As a result, there are no direct comparison scores available from the recorded measurements.

The AMD Ryzen 3 8300G does have a full set of individual benchmark scores. In Cinebench R15, it scores 1231 in multicore and 173 in singlecore. In Cinebench R20, it scores 5131 in multicore and 724 in singlecore. In Cinebench R23, it scores 12217 in multicore and 1724 in singlecore.

PassMark results for the AMD processor cover a range of workload types. The multithread score is 14018, and the single-thread score is 3778. Integer math scores 40534, floating point math scores 25336, and extended instructions score 12354. Data encryption scores 9115, data compression scores 158952, and random string sorting scores 19013. Physics scores 755, and find prime numbers scores 47.

The average benchmark score for the AMD processor is 18169. Its nearest rivals in the database are the AMD Ryzen 7 5700U with an average score of 18176 and a delta of 0 percent, the Intel Core i7-1365U also at 18177 with a delta of 0 percent, the Intel Core i7-9700 at 18180 with a delta of -0.1 percent, and the Intel Core i5-1334U at 18154 with a delta of 0.1 percent. These deltas are negligible, meaning the Ryzen 3 8300G sits in a tightly packed performance band around the 50th to 72nd percentile range.

The Intel Core 7 251E has no benchmark scores recorded in the database. Its average benchmark score is listed as 0, and its nearest rivals list is empty. The only performance metric available for the Intel part is its 50th percentile ranking among all CPUs. Without recorded scores, no quantitative comparison can be made between the two processors in any specific test.

This creates a significant limitation. The data shows the AMD processor's measured performance across numerous workloads, but there is no corresponding data for the Intel processor. Any claim about which processor is faster in a specific benchmark would require numbers that are not present in the database. The analysis must therefore rely on the architectural differences and the percentile rankings.

The percentile data offers one point of comparison. The AMD Ryzen 3 8300G ranks in the 72nd percentile of all CPUs, while the Intel Core 7 251E ranks in the 50th percentile. This suggests that, based on the database's overall ranking system, the AMD processor sits higher relative to the full CPU population. However, the percentile alone does not indicate the magnitude of any performance gap, and it does not replace direct benchmark scores.

The absence of Intel benchmark data also means the win counts remain at zero for both sides. The database records no wins for either processor in any test. This is consistent with the empty head-to-head table.

The Verdict

The recorded data supports a clear but incomplete picture. For the AMD Ryzen 3 8300G, there is a full set of benchmark results across Cinebench R15, R20, R23, and multiple PassMark tests. Those results place it in the 72nd percentile of all CPUs, with an average benchmark score of 18169. Its nearest rivals all sit within 0.1 percent of that average score, indicating that the AMD processor performs in line with a well-established group of mid-range chips.

For the Intel Core 7 251E, the database contains no benchmark scores whatsoever. The average score is listed as 0, and there are no nearest rivals. The only performance indicator is the 50th percentile ranking, which places it below the AMD processor in the overall distribution.

From a strict data perspective, the AMD Ryzen 3 8300G is the only one of the two with measurable performance evidence. Its 72nd percentile ranking exceeds the Intel part's 50th percentile ranking. The AMD processor also has a significantly lower launch MSRP of $176 compared to the Intel part's $384, though pricing should not be interpreted as a value judgment.

The architectural data favors the Intel processor in core count, threads, cache size, boost clock, PCIe generation, and memory bandwidth. The Intel part has 24 cores versus 4, 32 threads versus 8, 36 MB of L3 versus 8 MB, a 5.60 GHz boost versus 4.90 GHz, PCIe Gen 5 versus Gen 4, and 89.6 GB/s of memory bandwidth versus 83.2 GB/s. These are substantial specification advantages.

However, the database does not confirm whether those architectural advantages translate into benchmark wins. Without recorded scores for the Intel processor, the specification sheet cannot be validated against measured performance. The AMD processor, by contrast, has its performance confirmed across multiple tests.

The verdict from the data is conditional. If the question is which processor has recorded benchmark evidence of performance, the answer is the AMD Ryzen 3 8300G. If the question is which processor has the more capable specification sheet, the answer is the Intel Core 7 251E. The database does not allow a definitive performance winner.

Where Each One Wins

Based strictly on the database, the AMD Ryzen 3 8300G wins in the category of measured performance evidence. It has 17 recorded benchmark scores covering rendering, encryption, compression, math operations, and sorting. It ranks in the 72nd percentile of all CPUs, and its average benchmark score of 18169 places it within 0.1 percent of four nearest rivals. For any workload where benchmark verification matters, the AMD processor has the data to support its position.

The Intel Core 7 251E wins in the category of raw specifications. It has 24 cores and 32 threads, which is six times the core count and four times the thread count of the AMD part. Its 36 MB of L3 cache is more than four times the AMD processor's 8 MB. Its 5.60 GHz boost clock is 0.70 GHz higher. Its PCIe Gen 5 support with 16 lanes exceeds the AMD part's Gen 4 with 14 lanes. Its memory bandwidth of 89.6 GB/s is higher than the AMD part's 83.2 GB/s.

The Intel processor also supports both DDR4 and DDR5 memory, which gives it broader platform compatibility. The AMD processor is limited to DDR5. The Intel part has a larger die at 257 mm² compared to 137 mm², and it uses Intel's own foundry rather than TSMC.

The AMD processor wins on process technology. The 4 nm node is more advanced than Intel's 10 nm node, and the AMD die is smaller at 137 mm². The AMD processor also has a higher base clock at 3.40 GHz versus 2.10 GHz, which can benefit sustained workloads that do not rely on boost behavior.

The percentile ranking gives the AMD part an edge in overall standing. The 72nd percentile versus 50th percentile indicates that the database places the AMD processor higher among all CPUs. This is the only direct performance comparison available, and it favors AMD.

For use cases, the data suggests that the AMD Ryzen 3 8300G is positioned for workloads where confirmed benchmark performance matters, such as general desktop use, rendering, and math-heavy tasks, all evidenced by its recorded scores. The Intel Core 7 251E is positioned for workloads that demand massive parallel thread counts, large cache, and modern PCIe connectivity, as indicated by its specification sheet. The database does not include enough Intel data to determine which workloads would actually run faster on the Intel processor.
