AMD Ryzen 7 8700G vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The head-to-head benchmark suite contains 15 recorded comparisons between the AMD Ryzen 7 8700G and the Intel Core 3 305. The AMD part wins 11 of those comparisons, while the Intel part takes 4. The margin of victory, however, is far from even.

The largest single gap appears in PassMark integer math. The Ryzen 7 8700G scores 103107, while the Core 3 305 manages 32295. That is a 219.3% advantage for AMD, the biggest delta in the entire comparison. Data compression shows a similar pattern, with the AMD chip scoring 386811 versus 146857, a 163.4% lead. Random string sorting follows at 161.2% in favor of AMD, with scores of 46025 and 17623 respectively.

Extended instructions and encryption also heavily favor the Ryzen part. The 8700G posts 29067 in extended instructions against 13543 for the Core 3 305, a 114.6% difference. Data encryption shows the AMD chip at 22842 versus 11019, a 107.3% margin. PassMark multithread confirms the trend: 31690 for AMD, 15439 for Intel, a 105.3% delta.

The older Cinebench R15 multicore test shows the starkest single-core-to-multicore split. The Ryzen 7 8700G scores 2693, the Core 3 305 scores 1322, a 103.7% lead. Cinebench R23 multicore narrows that gap considerably: 17128 for AMD versus 13123 for Intel, a 30.5% advantage. Floating point math also favors AMD, 63815 against 42284, a 50.9% margin. Physics simulation gives the AMD chip a 33.6% lead, with scores of 1647 and 1233.

The Intel Core 3 305 wins four tests, but all by small margins. The most notable is Cinebench R23 single-core, where Intel scores 1852 against AMD's 1817, a 1.9% edge. PassMark single-thread shows Intel at 3977 versus 3928, a 1.2% lead, and the duplicate PassMark singlethread result matches that exactly. The final Intel win is PassMark find prime numbers, 115 versus 103, a 10.4% margin. Cinebench R15 single-core goes to AMD, 286 versus 186, a 53.8% lead.

Where Each One Wins

The benchmark data splits cleanly by workload type. The AMD Ryzen 7 8700G dominates anything that scales with core count, thread count, or parallel execution. Its 8 cores and 16 threads give it a structural advantage in multithreaded tests, and the results show it. Integer math, data compression, encryption, extended instructions, and random string sorting all favor AMD by margins ranging from roughly 51% to over 200%. These are compute-heavy tasks that use every available execution unit.

The Intel Core 3 305 wins only in single-threaded or lightly threaded scenarios, and even there the margins are thin. Its PassMark single-thread score of 3977 beats AMD's 3928 by just 1.2%. Cinebench R23 single-core shows a 1.9% Intel lead. The find prime numbers test, which is heavily dependent on scalar integer throughput, gives Intel a 10.4% edge. These wins indicate that the Core 3 305 has slightly better per-core efficiency in certain workloads, but the advantage is small enough that it will rarely decide real-world application performance.

In mixed workloads, the AMD part has the flexibility of 16 threads, which lets it handle background tasks while foreground applications run. The Intel part, with 6 cores and 6 threads, has no hyperthreading, so it cannot overlap work in the same way. The database shows this in the multithread PassMark result, where AMD leads by 105.3%. For workloads that alternate between single-threaded and multithreaded phases, the AMD chip's thread capacity gives it headroom that the Intel chip lacks.

The Cinebench R15 results are worth separate attention. The multicore test shows a 103.7% AMD lead, while the single-core test shows a 53.8% AMD lead. That single-core margin is the largest in any single-core test, and it suggests that older software, which relies on older instruction paths, may run noticeably better on the AMD chip.

The Verdict

The recorded data points in one direction. The AMD Ryzen 7 8700G is the stronger processor in the vast majority of tested workloads. It wins 11 of 15 head-to-head comparisons, and its victories are often by large margins. The Intel Core 3 305 wins 4 tests, all by single-digit percentages except for find prime numbers, which is a 10.4% edge. No Intel win exceeds 10.4%, while AMD wins range from 30.5% to 219.3%.

For users running multithreaded applications, render workloads, data compression, encryption, or any form of parallel compute, the Ryzen 7 8700G is the clear choice. Its integer math score is more than triple that of the Intel chip. Its data compression score is 2.6 times higher. Its multithread score is more than double. These are not marginal differences.

For users whose primary workloads are single-threaded, the Intel Core 3 305 offers a slight edge, but the margin is small. A 1.2% or 1.9% lead in single-thread tests is within run-to-run variance for many applications. The find prime numbers win, at 10.4%, is larger, but that test is a narrow synthetic measure of prime generation, not a general-purpose workload.

The average benchmark score in the database places the Ryzen 7 8700G at 33089, while the Core 3 305 sits at 18302. The AMD chip also ranks at the 83rd percentile of all CPUs, against the 72nd percentile for Intel. The Ryzen 7 8700G is the higher-performing part by a wide margin.
