AMD Ryzen 3 8300G vs Intel Core 5 330 Comparison

FAQ

Q: How do the average benchmark scores of the Intel Core 5 330 and AMD Ryzen 3 8300G compare?

A: The Intel Core 5 330 has an average benchmark score of 18,345, while the AMD Ryzen 3 8300G sits at 18,169. That puts the Intel part roughly 1% higher overall, and both chips land at the 72nd percentile among all CPUs in the database.

Q: Which processor wins more individual benchmark tests?

A: The Intel Core 5 330 wins 14 of the 17 head-to-head tests, while the AMD Ryzen 3 8300G wins only 3. The AMD victories are in data compression, integer math, and random string sorting.

Q: What is the largest single-test performance gap between these two chips?

A: The biggest margin is in PassMark's find prime numbers test, where the Intel Core 5 330 scores 114 versus the AMD Ryzen 3 8300G's 47, a 142.6% advantage for Intel. That is an enormous lead in a heavily integer-dependent workload.

Q: Do these processors use the same memory configuration?

A: No. The Intel Core 5 330 supports DDR5 and LPDDR5X over a single-channel memory bus with 59.7 GB/s bandwidth. The AMD Ryzen 3 8300G supports DDR5 over a dual-channel bus with 83.2 GB/s bandwidth, a materially higher throughput figure.

Q: Which chip has more cores and threads?

A: The Intel Core 5 330 has 6 cores and 6 threads (no simultaneous multithreading). The AMD Ryzen 3 8300G has 4 cores and 8 threads, relying on SMT to reach that thread count.

Q: Are both processors currently in production?

A: Yes, both are marked as Active in the database. The Intel Core 5 330 was released in April 2026, while the AMD Ryzen 3 8300G launched in January 2024.

Architecture Differences

The two chips come from fundamentally different design philosophies. The Intel Core 5 330 is built on a 3 nm process at Intel's own foundry, under the Wildcat Lake codename. It uses a monolithic 6-core, 6-thread layout with no hyperthreading. The AMD Ryzen 3 8300G, by contrast, is a 4 nm part fabricated by TSMC, based on the Zen 4 architecture with the Phoenix2 die. It packs 4 cores but 8 threads, using simultaneous multithreading to double logical execution.

Cache organization differs sharply. The Intel part has 192 KB of L1 cache, 2.5 MB of L2, and 6 MB of shared L3. AMD's chip provides 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. On a per-core basis, AMD's L2 allocation is more generous, but Intel's total L3 is smaller despite having more cores.

The process and transistor counts tell a story of their own. AMD lists 20,900 million transistors on a 137 mm² die; Intel does not disclose transistor count or die size in the database. The Intel chip's 3 nm node gives it a density advantage on paper, but the AMD part's 4 nm node from TSMC is a mature, well-characterized process.

Memory architecture is a major differentiator. The Intel Core 5 330 uses a single-channel memory bus, which caps theoretical bandwidth at 59.7 GB/s. It supports both DDR5 and LPDDR5X. AMD's Ryzen 3 8300G uses a dual-channel bus, reaching 83.2 GB/s, and supports only DDR5. That bandwidth gap of roughly 40% can matter in memory-sensitive tasks, though the benchmark data shows Intel still wins most tests.

PCIe connectivity also diverges. Intel provides Gen 4 with 6 CPU lanes, while AMD offers Gen 4 with 14 CPU lanes. AMD's ECC memory support is present (true), whereas Intel's is not (false). Both chips have integrated graphics: Intel uses Xe3 Graphics with 2 Xe cores, while AMD uses the Radeon 740M.

The market segments differ too. Intel's part is classified as Mobile, with a 15 W TDP and an Intel BGA 1516 socket. AMD's is a Desktop part with a 65 W TDP on Socket AM5. That TDP gap is 50 W, reflecting very different thermal envelopes and intended chassis.

The Verdict

The data points to the Intel Core 5 330 as the stronger overall performer. It wins 14 of 17 head-to-head comparisons, and its average benchmark score of 18,345 edges the AMD Ryzen 3 8300G's 18,169. In Cinebench tests, Intel leads by 7.6% to 7.7% across every variant, single-core and multi-core alike. That consistency is notable: the Intel chip is not just faster in one niche, it is faster across the entire Cinebench suite.

However, the AMD Ryzen 3 8300G is not without merits. It wins PassMark's data compression by 8.6%, integer math by 18%, and random string sorting by 6.5%. Those are specific workloads where AMD's Zen 4 architecture and higher memory bandwidth pay off. For users whose primary tasks involve compression or integer-heavy processing, the AMD part has a measurable edge.

The Intel Core 5 330 is the choice for single-thread responsiveness and general compute. Its passmark single-thread score of 4,088 versus AMD's 3,778 (8.2% higher) matters for everyday applications that rely on one core. The 142.6% lead in find prime numbers and 73.2% lead in floating-point math show Intel's architecture dominates certain math-heavy routines.

The AMD Ryzen 3 8300G makes sense for desktop builders who want a socketed AM5 platform, ECC memory support, and dual-channel bandwidth. Its 65 W TDP is higher, but it is a desktop part by design. The Intel chip is a mobile-focused 15 W processor, so it suits thin-and-light systems where power draw is critical.

Neither chip is a clear winner across every metric. The Intel Core 5 330 wins more tests and has a slightly higher average score. The AMD Ryzen 3 8300G wins in integer math, compression, and sorting, and offers more PCIe lanes and memory bandwidth. The decision hinges on workload: Intel for broad compute and single-thread speed, AMD for specific integer and memory-bound tasks.

Head-to-Head Benchmarks

The Cinebench results paint a uniform picture. The Intel Core 5 330 leads by 7.6% in Cinebench R15 multi-core (1,325 versus 1,231) and by 7.5% in R15 single-core (186 versus 173). The gap holds steady in R20: 7.6% for multi-core (5,523 versus 5,131) and 7.6% for single-core (779 versus 724). Cinebench R23 shows the same pattern, with Intel ahead 7.6% in multi-core (13,150 versus 12,217) and 7.7% in single-core (1,856 versus 1,724). These are consistent margins, suggesting the Intel chip's higher boost clock of 4.60 GHz versus 4.90 GHz does not translate into AMD winning any Cinebench test.

PassMark's suite reveals more varied results. Intel wins data encryption by 21.5% (11,076 versus 9,115), a substantial margin. Extended instructions go Intel's way by 3.7% (12,808 versus 12,354). The find prime numbers test is a blowout: Intel scores 114 versus AMD's 47, a 142.6% difference. Floating-point math favors Intel heavily at 73.2% (43,885 versus 25,336). Physics testing shows Intel ahead 59.1% (1,201 versus 755). Multithread performance goes to Intel by 10.4% (15,471 versus 14,018), and single-thread tests give Intel an 8.2% edge (4,088 versus 3,778 in both single-thread variants).

AMD's three wins are all in memory or integer-oriented workloads. Data compression goes to AMD by 8.6% (158,952 versus 145,287). Integer math favors AMD by 18% (40,534 versus 33,258). Random string sorting goes AMD's way by 6.5% (19,013 versus 17,771). These wins align with AMD's dual-channel memory bus and higher memory bandwidth of 83.2 GB/s versus 59.7 GB/s.

The overall tally is decisive: Intel wins 14 tests, AMD wins 3. The Intel Core 5 330 also holds a slightly higher average benchmark score (18,345 versus 18,169) and matches AMD's 72nd percentile ranking among all CPUs. In the nearest-rival comparison, Intel sits within 0.2% of the Core i3-13100 and Core 7 360, while AMD is within 0.1% of the Ryzen 7 5700U and Core i7-1365U. Both chips are tightly clustered with their direct competitors, but Intel's head-to-head dominance over AMD is clear.
