AMD Ryzen 3 8300G vs Intel Core 7 251TE Comparison

The Verdict

The benchmark data presents a clear performance hierarchy between these two desktop processors. The Intel Core 7 251TE wins 15 of 17 recorded head-to-head comparisons, while the AMD Ryzen 3 8300G wins only 2. The Intel part holds an average benchmark score of 41650 against 18169 for the AMD, placing it in the 88th percentile of all CPUs versus the 72nd percentile for the Ryzen. The Intel Core 7 251TE sits alongside the Intel Core Ultra 7 265H and Intel Core i7-14650HX in the database's nearest-rival grouping, with a delta of 0.1% and 0.2% respectively. The AMD Ryzen 3 8300G, by contrast, aligns with the AMD Ryzen 7 5700U and Intel Core i7-1365U, both at a 0% delta. The data indicates that the Intel part is the choice for users prioritizing raw multi-threaded throughput, while the AMD part has one specific strength: single-thread performance in the PassMark test suite.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 3 8300G uses the Zen 4 architecture on a 4 nm TSMC process node, with a 137 mm² die size containing 20,900 million transistors. Its codename is Phoenix2, and it belongs to the 8000 series. The Intel Core 7 251TE uses the Bartlett Lake codename on a 10 nm Intel process node, with a larger 215 mm² die size. The Intel part does not have a listed architecture name in the database, only the codename and generation designation.

Core counts differ substantially. The AMD processor has 4 cores and 8 threads. The Intel processor has 24 cores and 32 threads. Cache hierarchies also diverge: the AMD part provides 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. The Intel part provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 36 MB of shared L3. The Intel L3 cache is 4.5 times larger than the AMD L3 cache.

Memory support shows a key difference. The AMD Ryzen 3 8300G supports only DDR5 memory, while the Intel Core 7 251TE supports both DDR4 and DDR5. Both run dual-channel memory buses, but the Intel part has a higher listed memory bandwidth at 89.6 GB/s versus 83.2 GB/s for the AMD. Both support ECC memory. PCIe capability also differs: the AMD part provides Gen 4 with 14 lanes from the CPU, while the Intel part provides Gen 5 with 16 lanes from the CPU.

The integrated graphics differ as well. The AMD processor uses the Radeon 740M, while the Intel processor uses the UHD Graphics 770. The AMD part has a base clock of 3.40 GHz and a boost clock of 4.90 GHz, while the Intel part has a base clock of 1.40 GHz and a boost clock of 5.40 GHz. The Intel processor has a 45 W TDP, the AMD processor has a 65 W TDP. Neither processor has an unlocked multiplier.

Where Each One Wins

The AMD Ryzen 3 8300G wins only in the PassMark single-thread test, scoring 3778 against 3568 for the Intel part, a 5.9% advantage. This result appears in both the passmark_single_thread and passmark_singlethread entries, confirming the same measurement. The data shows that in this specific workload, the higher boost clock of the Intel part does not translate into a single-thread win, and the AMD part's per-core efficiency carries the result.

The Intel Core 7 251TE dominates every other recorded workload. The largest margins appear in floating-point math, where the Intel part scores 85607 against 25336, a 70.4% advantage. Integer math shows a 67.8% lead with 125739 versus 40534. Prime number finding shows a 66.4% lead with 140 versus 47. Data encryption shows a 58.9% lead with 22176 versus 9115. Physics simulation shows a 61% lead with 1938 versus 755. Multithread performance shows a 53.3% lead with 30022 versus 14018. Data compression shows a 52.5% lead with 334399 versus 158952. Random string sorting shows a 52% lead with 39643 versus 19013.

Cinebench results follow the same pattern. The Intel part leads by 52.1% in Cinebench R15 multicore, R20 multicore, and R23 multicore. It leads by 52.2% in Cinebench R15 singlecore and 52.1% in R20 and R23 singlecore. The extended instructions test shows the smallest Intel lead among PassMark tests at 27.2%, with scores of 16974 versus 12354.
