AMD Ryzen 3 8300G vs Intel Core i7-1365U Comparison

The Intel Core i7-1365U and AMD Ryzen 3 8300G present a fascinating clash of design philosophies, with benchmark results revealing a near-split decision. The data shows the Intel part winning 9 of 17 head-to-head tests, while the AMD chip takes 8, yet the magnitude of those victories paints a clearer picture of their respective strengths. This is not a story of a clear overall winner, but rather one of workload-specific dominance.

Head-to-Head Benchmarks

The most dramatic divergence appears in the Cinebench suite, where the two processors trade blows across different rendering loads. In Cinebench R23 multi-core, the AMD Ryzen 3 8300G delivers a decisive victory, scoring 12217 against Intel's 8946, a substantial 26.8% advantage. This is the single largest delta in the entire benchmark set and indicates that the Ryzen 3's four high-power Zen 4 cores are exceptionally effective at sustained multi-threaded rendering. However, the Intel Core i7-1365U strikes back in Cinebench R23 single-core, scoring 1887 versus 1724, a 9.5% lead, suggesting its higher boost clock of 5.20 GHz provides a tangible edge in lightly-threaded tasks.

The older Cinebench tests tell a more contradictory story. In Cinebench R15, the Intel chip wins both multi-core and single-core tests by wide margins: 1466.5 versus 1231 (19.1% ahead) in multi-core, and an enormous 265.5 versus 173 (53.5% ahead) in single-core. Yet in Cinebench R20, the AMD part flips the script, winning multi-core with 5131 against 4882 (4.9% ahead) and single-core with 724 against 689 (4.8% ahead). This inconsistency between R15, R20, and R23 suggests that the benchmark's evolution has changed how it scales with core counts, cache sizes, or clock behavior, making direct comparisons across versions unreliable for predicting real-world performance.

Beyond Cinebench, the PassMark suite reveals a clear split in computational specialties. The Intel Core i7-1365U dominates in arithmetic and physics-heavy workloads. It leads by 33% in floating-point math (33689 versus 25336) and by 25.5% in integer math (50881 versus 40534). Its advantage extends to physics simulations, where it scores 966 against 755 (a 27.9% gap), and to prime number finding, where it wins 58 to 47 (23.4% ahead). These results point to a processor with superior per-core execution resources for certain types of calculations.

Conversely, the AMD Ryzen 3 8300G demonstrates clear superiority in memory-intensive and instruction-heavy tasks. It crushes Intel in extended instructions (SIMD), scoring 12354 versus 8321, a massive 32.6% advantage. It also wins in data compression (158952 versus 149585, 5.9% ahead) and random string sorting (19013 versus 16977, 10.7% ahead). In single-threaded PassMark, the AMD chip leads with 3778 against 3411, a 9.7% advantage, which contradicts the Cinebench R23 single-core result, underscoring that different single-threaded tests measure different aspects of performance. The multi-threaded PassMark score is essentially a tie, with Intel winning by a razor-thin 0.2% (14045 versus 14018), while Intel also edges out a 4.6% win in data encryption (9531 versus 9115). The overall average benchmark scores are virtually identical, with Intel at 18177 and AMD at 18169, and both processors sit at the 72nd percentile among all CPUs.

Architecture Differences

The fundamental architectural divide is stark. The Intel Core i7-1365U is built on Intel's 10 nm process node and uses the Raptor Lake architecture, specifically the Raptor Lake-U mobile variant. It features 10 cores and 12 threads, a configuration that implies a hybrid layout of performance and efficiency cores. Its base clock is 1800.00 MHz, but it can boost up to 5.20 GHz. In contrast, the AMD Ryzen 3 8300G is a desktop part built on TSMC's 4 nm process, using the Zen 4 architecture with the Phoenix2 codename. It has 4 cores and 8 threads, a more traditional high-performance layout, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz.

The cache hierarchies are also fundamentally different in size and layout. Intel allocates 80 KB of L1 cache per core, 1.25 MB of L2 per core, and a shared 12 MB L3 cache. AMD's design uses 64 KB of L1 per core, 1 MB of L2 per core, and a smaller 8 MB shared L3 cache. This difference in L3 capacity could explain some of the divergent scores in memory-sensitive benchmarks, though the AMD part compensates with a higher memory bandwidth of 83.2 GB/s, a figure not listed for Intel.

Perhaps the most telling difference is in power and thermal design. The Intel part has a TDP of 15 watts, targeting thin-and-light mobile devices, while the AMD Ryzen 3 8300G has a TDP of 65 watts, a desktop-class power envelope. This 50-watt difference is the context for the performance deltas; the AMD chip has far more thermal headroom to sustain high clocks, while the Intel chip is constrained to a much lower power budget. The Intel part is also a mobile processor on the Intel BGA 1744 socket, whereas the AMD chip uses the desktop AMD Socket AM5. Memory support differs as well, with Intel supporting both DDR4 and DDR5, while AMD exclusively supports DDR5 and also offers ECC memory support, which Intel lacks. PCIe lane counts also differ, with AMD providing 14 Gen 4 lanes (CPU only) versus Intel's 8 Gen 4 lanes.

The Verdict

The benchmark data indicates that the choice between these two processors should be dictated by the target workload and platform constraints. The AMD Ryzen 3 8300G, with its 65-watt TDP and desktop AM5 platform, is the clear choice for sustained multi-threaded rendering, as evidenced by its 26.8% lead in Cinebench R23 multi-core. It also excels in SIMD-heavy tasks, leading by 32.6% in extended instructions, and shows superior memory bandwidth. Users building a desktop system focused on content creation, 3D rendering, or data compression would find the AMD part's performance profile more compelling.

The Intel Core i7-1365U, despite its low 15-watt TDP, proves itself to be a formidable contender in specific areas. Its 33% lead in floating-point math and 25.5% lead in integer math make it a stronger choice for scientific calculations, physics simulations, and financial modeling. It also holds a 9.5% advantage in Cinebench R23 single-core, suggesting it is better suited for lightly-threaded tasks that rely on high clock speeds. Given its mobile BGA socket and 15-watt power envelope, it is designed for laptops where power efficiency is paramount, and the data shows it can deliver competitive performance in that context.

There is no universal winner. The overall average benchmark scores are effectively tied, with a 0.04% difference. The Intel part's 9 wins versus AMD's 8 wins in individual tests are nearly balanced. The final decision hinges on the user's platform: for a desktop system with a 65-watt budget, the AMD Ryzen 3 8300G offers superior multi-threaded rendering and SIMD performance. For a mobile device with a 15-watt power limit, the Intel Core i7-1365U provides a compelling mix of high-clocked single-core performance and strong arithmetic throughput. The data does not support a single recommendation; it supports a workload-specific one.
