AMD Ryzen 3 PRO 8300G vs Intel Core 9 273PE Comparison

The AMD Ryzen 3 PRO 8300G and Intel Core 9 273PE occupy different tiers of the desktop processor market, and the benchmark data confirms a decisive performance gap. The Intel Core 9 273PE wins every head-to-head benchmark in the database, with the largest margins appearing in heavily threaded workloads. The AMD part is a 4-core, 8-thread Zen 4 design, while the Intel part is a 12-core, 24-thread Bartlett Lake processor, and that resource difference drives most of the recorded deltas. The database records the Intel part at the 90th percentile of all CPUs, compared to the 71st percentile for the AMD part. The average benchmark score for the Intel part is 49845, while the AMD part averages 17278, a gap that places them in entirely different performance classes. This analysis walks through the specific benchmark wins, the architectural reasons for the split, and the specification differences that separate the two.

Head-to-Head Benchmarks

The Intel Core 9 273PE holds a commanding lead across the entire Cinebench suite. In Cinebench R15 multicore, the Intel part scores 3153 against 1245 for the AMD Ryzen 3 PRO 8300G, a delta of -60.5%. The single-core R15 test shows a similar pattern: 445 for Intel versus 175 for AMD, also a -60.7% delta. Moving to Cinebench R20, the Intel part scores 13140 multicore and 1855 single-core, while the AMD part scores 5190 and 732 respectively, with deltas of -60.5% in both. Cinebench R23 follows the same trend: 31288 for Intel versus 12359 for AMD in multicore, and 4417 versus 1744 in single-core, both at -60.5% deltas. The consistency of the -60.5% delta across the R20 and R23 tests suggests a stable performance ratio in those workloads, not a workload-specific anomaly.

The Passmark suite shows the widest margins. Floating point math is the largest gap in the entire comparison: the Intel part scores 107884, while the AMD part scores 23374, a delta of -78.3%. Integer math shows a -73.3% delta, with Intel at 139410 and AMD at 37292. Physics performance is another major differentiator: Intel scores 3120 versus AMD's 772, a -75.3% delta. Prime number finding shows Intel at 203 versus AMD at 47, a -76.8% delta, indicating a substantial advantage in that specific algorithmic workload.

The closest result in the entire dataset is Passmark single-thread performance. Intel scores 3650, AMD scores 3550, a delta of only -2.7%. This is notable because it shows that in a purely single-threaded Passmark context, the two processors are nearly comparable. The Intel part still wins, but the margin is small enough to suggest that the AMD Zen 4 core design is competitive on a per-thread basis in that specific test. However, the Cinebench single-core results tell a different story: the Intel part leads by -60.7% in R15 and -60.5% in R20 and R23, which indicates that the Cinebench single-core workload is more sensitive to the Intel part's higher boost clock.

Other Passmark tests show intermediate gaps. Data compression shows Intel at 405885 versus AMD at 150567, a -62.9% delta. Data encryption shows a -62.1% delta, with Intel at 22719 and AMD at 8607. Extended instructions show a -53.5% delta, with Intel at 24630 and AMD at 11451. Random string sorting shows a -56.3% delta, with Intel at 45098 and AMD at 19703. Multithread performance shows a -63.7% delta, with Intel at 36810 and AMD at 13368. The Intel part wins all 17 recorded head-to-head tests, with the AMD part recording zero wins.

Where Each One Wins

The Intel Core 9 273PE wins every benchmark in the database, so the analysis of where each processor wins is really an analysis of where the Intel advantage is largest versus smallest. The largest Intel margins appear in floating point math (-78.3%), prime number finding (-76.8%), and physics (-75.3%). These are workloads that scale heavily with core count and thread count, and the Intel part's 12 cores and 24 threads provide a structural advantage over the AMD part's 4 cores and 8 threads. The data indicates that the Intel part is particularly strong in compute-heavy, parallel workloads.

The smallest Intel margin is in Passmark single-thread performance, at -2.7%. This narrow gap suggests that the AMD part's Zen 4 architecture delivers competitive per-thread performance in that specific workload. The AMD part's boost clock of 4.90 GHz is lower than the Intel part's 5.70 GHz, but the Passmark single-thread test appears to be less sensitive to that difference than the Cinebench single-core tests, where the Intel margin is much larger.

The AMD Ryzen 3 PRO 8300G does not win any category, but the data shows where it is least disadvantaged. In extended instructions, the delta is -53.5%, which is the smallest margin among the multi-threaded Passmark tests. In random string sorting, the delta is -56.3%. These are cases where the AMD part's per-core efficiency partially offsets its lower core count. The AMD part also shows a relatively smaller gap in data compression (-62.9%) compared to floating point math (-78.3%), indicating that the workload mix matters.

For use-case analysis, the Intel part is the clear choice for any workload that can utilize multiple cores. Rendering, physics simulation, encryption, and integer-heavy tasks all show Intel leads of at least 62%. The AMD part's closest performance comes in single-threaded Passmark workloads, where the gap narrows to under 3%. For workloads that are single-threaded and Passmark-specific, the two processors are nearly equivalent, but for everything else, the Intel part is substantially faster.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 3 PRO 8300G is built on the Zen 4 architecture with the Phoenix2 codename, fabricated on a 4 nm process at TSMC. The Intel Core 9 273PE uses the Bartlett Lake codename, fabricated on a 10 nm process at Intel. The process node difference is significant: the AMD part uses a more advanced 4 nm node, while the Intel part uses 10 nm. Despite the older node, the Intel part achieves higher performance, which indicates that core count and clock speed are the dominant factors in this comparison.

Core and thread counts differ sharply. The AMD part has 4 cores and 8 threads, while the Intel part has 12 cores and 24 threads, a 3x core advantage and a 3x thread advantage for Intel. The cache configurations reflect this difference. The AMD part has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of shared L3 cache. The Intel part has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Intel L3 cache is 4.5 times larger in total, which helps in workloads with large working sets.

Clock speeds also favor the Intel part. The AMD part has a base clock of 3.40 GHz and a boost clock of 4.90 GHz. The Intel part has a base clock of 2.30 GHz and a boost clock of 5.70 GHz. The Intel part has a lower base clock but a substantially higher boost clock, which explains its lead in single-threaded Cinebench tests. Both processors have a TDP of 65, so the power envelope is identical, but the Intel part delivers significantly more performance within that envelope.

Memory support differs. The AMD part supports DDR5 only, with a dual-channel memory bus and 83.2 GB/s bandwidth. The Intel part supports both DDR4 and DDR5, also with a dual-channel bus, and has 89.6 GB/s bandwidth. The Intel part has slightly higher memory bandwidth. Both support ECC memory. PCIe support also differs: the AMD part uses PCIe Gen 4 with 14 lanes, while the Intel part uses PCIe Gen 5 with 16 lanes. The Intel part has a newer PCIe standard and more lanes.

The integrated graphics differ as well. The AMD part uses the Radeon 740M, while the Intel part uses the UHD Graphics 730. The AMD part is a desktop processor in the 8000 series, released on 2024-04-15. The Intel part is a desktop processor in the Core 9 series, released on 2026-03-08. The Intel part has a launch MSRP of $549. Both parts have locked multipliers, so neither supports unlocked overclocking.
