AMD Ryzen 3 PRO 8300G vs Intel Core 3 305 Comparison

The Verdict

The benchmark database shows a clear overall winner in the Intel Core 3 305, which takes 14 of the 17 recorded head-to-head tests. The AMD Ryzen 3 PRO 8300G wins only three tests. The Intel part also holds a higher average benchmark score of 18302 versus 17278 for the AMD, and it sits in the 72nd percentile of all CPUs compared to the 71st percentile for the AMD. The Intel Core 3 305 is the faster processor in the majority of workloads, and its nearest rival list confirms it trades blows with the Intel Core i3-14100 (0.1% behind), the Intel Core 5 330 (0.2% behind), and the Intel Core 7 360 (0.4% behind). The AMD Ryzen 3 PRO 8300G, by contrast, sits within 0.6% of the Intel Core i5-11400F and is essentially tied with the AMD Ryzen 5 4500 (0.3% ahead) and AMD Ryzen 3 210 (0.2% behind).

The AMD part does have a specific role. It wins in integer math, data compression, and random string sorting, which points toward general desktop responsiveness and certain productivity tasks. The Intel part wins in every Cinebench rendering test, all single-thread tests, and the majority of PassMark math and encryption workloads. The data indicates that anyone prioritizing multi-core rendering or floating-point compute should choose the Intel Core 3 305. The AMD Ryzen 3 PRO 8300G remains a valid choice for integer-heavy workloads, but the overall record favors Intel.

Where Each One Wins

The Intel Core 3 305 dominates the rendering benchmarks. In Cinebench R15, R20, and R23, it wins both single-core and multi-core tests by a consistent margin of 5.8% to 5.9%. The single-thread PassMark score also goes to Intel at 3977 versus 3550, a 10.7% lead. The Intel part extends its advantage in floating-point math (42284 versus 23374, a 44.7% lead), physics (1233 versus 772, a 37.4% lead), and data encryption (11019 versus 8607, a 21.9% lead). The Intel chip also wins in extended instructions (13543 versus 11451, a 15.4% lead) and prime number finding (115 versus 47, a 59.1% lead).

The AMD Ryzen 3 PRO 8300G wins only where its architecture favors integer throughput. It beats the Intel part by 15.5% in integer math (37292 versus 32295), by 11.8% in random string sorting (19703 versus 17623), and by 2.5% in data compression (150567 versus 146857). These are narrow but consistent wins in CPU integer workloads. The AMD part also has a higher multithread score in PassMark (13368 versus 15439, but that is a loss), so its wins do not translate into an overall multithread victory.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 3 PRO 8300G uses the Zen 4 architecture on the Phoenix2 die, built on a 4 nm process at TSMC. It has 4 cores and 8 threads, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process at Intel, with 6 cores and 6 threads. Its base clock is much lower at 1.50 GHz, but the boost clock reaches 4.30 GHz. The Intel part has no multithreading, so its 6 cores operate as 6 threads, while the AMD part uses simultaneous multithreading to double its thread count from 4 to 8.

The cache layouts differ substantially. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. The Intel chip has 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The AMD part draws 65 W TDP, while the Intel part is rated at only 15 W, reflecting its mobile market segment. The AMD chip uses AMD Socket AM5, while the Intel chip uses Intel BGA 1516, confirming the Intel part is a mobile soldered processor. The AMD part supports DDR5 memory on a dual-channel bus with 83.2 GB/s bandwidth, while the Intel part supports DDR5 and LPDDR5X on a single-channel bus with 59.7 GB/s. The AMD chip supports ECC memory; the Intel chip does not. The AMD chip provides Gen 4 PCIe with 14 lanes, while the Intel chip provides Gen 4 PCIe with only 6 lanes.

The integrated graphics also differ. The AMD Ryzen 3 PRO 8300G uses the Radeon 740M, while the Intel Core 3 305 uses Intel Xe3 Graphics with one Xe core. The AMD part was released in April 2024, while the Intel part carries a release date of April 2026 and a launch MSRP of $309. The AMD part has no launch MSRP recorded in the database.

Head-to-Head Benchmarks

The Intel Core 3 305 wins every Cinebench test by the same narrow margin. In Cinebench R15 multi-core, it scores 1322 against 1245, a 5.8% lead. In R15 single-core, it scores 186 against 175, a 5.9% lead. The R20 multi-core result is 5511 versus 5190 (5.8%), and R20 single-core is 777 versus 732 (5.8%). In R23 multi-core, the Intel part scores 13123 versus 12359 (5.8%), and in R23 single-core it scores 1852 versus 1744 (5.8%). These consistent margins suggest a clock-for-clock advantage in rendering workloads, despite the Intel part's lower base clock of 1.50 GHz versus 3.40 GHz.

The largest single win for the Intel part comes in PassMark floating-point math. The Intel Core 3 305 scores 42284, which is 44.7% ahead of the AMD's 23374. This is a massive gap in a compute-heavy workload. The Intel part also wins by 59.1% in find prime numbers (115 versus 47) and by 37.4% in physics (1233 versus 772). These results indicate that the Intel architecture handles floating-point and scientific workloads far more efficiently in this comparison.

The AMD Ryzen 3 PRO 8300G's best win is in PassMark integer math, where it scores 37292 against 32295, a 15.5% lead. It also wins random string sorting by 11.8% (19703 versus 17623) and data compression by 2.5% (150567 versus 146857). These wins show that the AMD part retains an edge in integer-heavy tasks, but the overall PassMark multithread score still favors Intel at 15439 versus 13368, a 13.4% lead. The single-thread PassMark score also favors Intel at 3977 versus 3550, a 10.7% lead.

The data encryption test shows a notable Intel advantage of 21.9% (11019 versus 8607), and extended instructions favor Intel by 15.4% (13543 versus 11451). The Intel part wins 14 of 17 tests, and the three AMD wins are all in integer or data-handling categories. The head-to-head record, combined with the average benchmark scores and percentile rankings, places the Intel Core 3 305 clearly ahead in overall performance. The AMD Ryzen 3 PRO 8300G remains competitive only in specific integer workloads, and its overall benchmark average of 17278 is 5.6% behind the Intel part's 18302.
