AMD Ryzen 3 8300G vs AMD Ryzen 5 1600 Comparison

The AMD Ryzen 5 1600 and AMD Ryzen 3 8300G represent two very different eras of AMD desktop silicon, and the benchmark data reflects that gap clearly. The Ryzen 3 8300G wins 11 of the 15 head-to-head tests, often by massive margins, while the Ryzen 5 1600 takes 4 wins in specific data-processing tasks. The 8300G is the faster all-around processor by average benchmark score (18169 vs 17994), and it lands in the same 72nd percentile of all CPUs, but that average masks how differently these two chips behave. The Ryzen 5 1600 is a six-core, twelve-thread Zen part from 2017 with a 3.20 GHz base and 3.60 GHz boost clock. The Ryzen 3 8300G is a four-core, eight-thread Zen 4 part from 2024 with a 3.40 GHz base and a 4.90 GHz boost clock. The data shows the newer chip is dramatically faster per core, while the older chip retains narrow leads in a few memory-heavy or multi-threaded workloads.

The Verdict

Choose the AMD Ryzen 3 8300G if you want the faster processor for most modern workloads. Its single-core performance is dominant: it scores 3778 in PassMark single-thread versus 2066 for the Ryzen 5 1600, a 45.3% lead. In Cinebench R23 multi-core, the 8300G scores 12217 against 6468, which is 47.1% ahead. This is not a close contest in raw compute. The 8300G also brings integrated Radeon 740M graphics, which the Ryzen 5 1600 lacks entirely, making it a complete package for a system without a discrete GPU. Its 65W TDP matches the Ryzen 5 1600, but it delivers that performance on a 4 nm TSMC process versus a 14 nm GlobalFoundries node.

Pick the AMD Ryzen 5 1600 only if you have a specific workload that favors its six physical cores and 12 threads. It wins PassMark data compression (172053 vs 158952, 8.2% ahead), data encryption (11683 vs 9115, 28.2% ahead), integer math (41470 vs 40534, 2.3% ahead), and random string sorting (20240 vs 19013, 6.5% ahead). These are narrow wins in niche tests. The Ryzen 5 1600 also uses the AM4 socket and DDR4 memory, which may be relevant if you are upgrading an existing platform. However, its overall average benchmark score is lower, and it loses the multi-thread PassMark test (12270 vs 14018, 12.5% behind) despite having more threads. The data is clear: the 8300G is the better buy for a new build, and the 1600 is only justified for legacy AM4 systems or those specific encryption/compression tasks.

Architecture Differences

The two chips come from entirely different design generations. The Ryzen 5 1600 uses the Zen architecture on a 14 nm process at GlobalFoundries, with a die size of 213 mm² and 4,800 million transistors. The Ryzen 3 8300G uses Zen 4 on a 4 nm process at TSMC, with a smaller 137 mm² die but a much higher transistor count of 20,900 million. That transistor density is the foundation of the 8300G's performance advantage.

Core and cache configurations differ substantially. The 1600 has 6 cores and 12 threads, with 96 KB L1 cache per core and 512 KB L2 per core, plus 16 MB shared L3 cache. The 8300G has 4 cores and 8 threads, with 64 KB L1 per core and 1 MB L2 per core, plus 8 MB shared L3. The 8300G gives each core more L2 cache, which helps single-threaded performance, but the 1600 has twice the total L3. The 8300G compensates with a much higher boost clock of 4.90 GHz versus 3.60 GHz.

Memory and connectivity also separate them. The 1600 supports DDR4 with dual-channel memory and 42.7 GB/s bandwidth, while the 8300G supports DDR5 with dual-channel memory and 83.2 GB/s bandwidth — nearly double the theoretical bandwidth. The 8300G also uses PCIe Gen 4 with 14 CPU lanes, versus Gen 3 with 16 lanes on the 1600. Both support ECC memory and have unlocked multipliers on the 1600, but the 8300G's multiplier is locked. The 8300G includes Radeon 740M integrated graphics; the 1600 has none. The 8300G uses the AM5 socket, while the 1600 uses AM4, meaning they are not interchangeable in a motherboard.

Head-to-Head Benchmarks

The biggest single-core win for the Ryzen 3 8300G comes in Cinebench R23 single-core: 1724 versus 915, a 46.9% lead. That is nearly double the score. The same test in Cinebench R15 shows a 15% lead (173 vs 147), which is smaller but still decisive. PassMark single-thread shows the 8300G at 3778 versus 2066, a 45.3% advantage. The data consistently shows the Zen 4 core is far more efficient per clock.

Multi-core results are more nuanced. In Cinebench R23 multi-core, the 8300G scores 12217 against 6468, a 47.1% lead, which is surprising given the 1600 has 6 cores versus 4. The 8300G's higher clock speed and IPC overcome the core deficit. In Cinebench R15 multi-core, the 8300G wins 1231 to 1129, an 8.3% margin. PassMark multi-thread shows a 12.5% lead for the 8300G (14018 vs 12270). The 1600's extra threads do not help it win any of the Cinebench multi-core tests.

The Ryzen 5 1600's wins are all in PassMark's data-processing suite. Data encryption is its largest victory: 11683 versus 9115, a 28.2% margin. Data compression follows at 8.2% (172053 vs 158952). Random string sorting is 6.5% ahead (20240 vs 19013), and integer math is 2.3% ahead (41470 vs 40534). These are the only tests where the older chip's architecture shows an edge. The 8300G wins extended instructions (12354 vs 6667, 46% lead), prime numbers (47 vs 35, 25.5% lead), floating point math (25336 vs 21402, 15.5% lead), and physics (755 vs 643, 14.8% lead).

Where Each One Wins

The Ryzen 3 8300G wins in almost every general-purpose and compute-heavy scenario. It dominates single-threaded tests, which translates to snappier application responsiveness and better performance in lightly-threaded software. Its Cinebench R23 multi-core score of 12217 is nearly double the 1600's 6468, so it is the clear choice for video encoding, 3D rendering, and other heavily multithreaded content creation tasks. The 8300G also wins PassMark extended instructions (12354 vs 6667) and floating-point math (25336 vs 21402), indicating stronger SIMD and scientific computing capability. Its integrated Radeon 740M graphics mean it can power a full desktop system without a discrete GPU, and its DDR5 support with 83.2 GB/s bandwidth gives it a future-proof memory path. The 8300G's 4.90 GHz boost clock is the highest clock speed in this comparison, and it achieves this at the same 65W TDP as the 1600.

The Ryzen 5 1600 wins in four specific PassMark tests: data encryption (28.2% ahead), data compression (8.2% ahead), random string sorting (6.5% ahead), and integer math (2.3% ahead). These are narrow wins in niche workloads, suggesting the 1600's six-core layout with more L3 cache (16 MB vs 8 MB) benefits certain data-manipulation tasks. If your primary use case is file compression, encryption, or database-style string operations, the 1600 holds a measurable advantage. It also uses the AM4 socket and DDR4 memory, which may be an advantage if you already own an AM4 motherboard and want a drop-in upgrade. However, these wins are the exception rather than the rule — the 8300G wins 11 of 15 head-to-head tests, including every Cinebench test and the overall PassMark multi-thread metric. For a new build, the 8300G is the better all-around processor; for a specific legacy workload on AM4, the 1600 still has a role.
