AMD Ryzen 3 8300GE vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen 3 8300GE and the Intel Core 3 305 shows a decisive overall advantage for the Intel part, which wins 14 of the 17 recorded head-to-head tests. The AMD processor claims only 3 wins, but those wins are concentrated in specific workloads where its architecture holds a clear edge.

Starting with the broadest measure, the average benchmark score tells the story: the Intel Core 3 305 records 18,302 against 17,614 for the AMD Ryzen 3 8300GE, a gap of roughly 3.9%. The Intel chip also sits at the 72nd percentile among all CPUs in the database, one point above the AMD part's 71st percentile. This places both processors in the same performance tier, but the Intel chip consistently pulls ahead in most measured tasks.

The Cinebench results are uniform: Intel wins every single test by exactly 10.8%. In Cinebench R23 multi-core, the Intel Core 3 305 scores 13,123 against 11,705 for the AMD, and in single-core it posts 1,852 versus 1,652. The same 10.8% margin appears across R15 and R20 in both single and multi-core variants. This consistency suggests a fundamental per-thread advantage for the Intel design rather than a workload-specific quirk.

The Passmark suite reveals a more nuanced picture. The largest Intel victory comes in the prime number search test, where it scores 115 versus just 44 for the AMD chip, a 61.7% advantage. Floating point math also heavily favors Intel at 42,284 versus 24,681, a 41.6% gap. Physics simulation shows Intel ahead by 39.2% (1,233 versus 750), and data encryption goes to Intel by 21.9% (11,019 versus 8,603). Extended instructions, multi-threaded throughput, and single-thread performance all favor Intel by margins between 8.4% and 12.5%.

The AMD processor's wins are narrower but still meaningful. Integer math is its strongest result: 39,163 versus 32,295, a 21.3% advantage for AMD. Data compression goes to AMD by 5.7% (155,164 versus 146,857), and random string sorting shows a modest 2.2% edge (18,010 versus 17,623). These three wins share a common theme: they are workloads where the AMD chip's simultaneous multi-threading (SMT) can leverage its 8 threads against the Intel chip's 6 physical threads with no hyper-threading.

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 3 8300GE uses the Zen 4 architecture on a 4 nm TSMC process, with the Phoenix2 codename and 20,900 million transistors on a 137 mm² die. It is a desktop part for AMD Socket AM5, released in April 2024, with a 35 W TDP.

The Intel Core 3 305 uses the Wildcat Lake codename on a 3 nm Intel process. It is a mobile part on Intel BGA 1516, with a release date of April 2026 and a 15 W TDP. The database records no transistor count or die size for the Intel chip, and no architecture name beyond the codename.

The core configurations differ significantly. The AMD chip has 4 cores and 8 threads, using SMT to double its thread count. The Intel chip has 6 cores and 6 threads, with no hyper-threading. Despite having fewer cores, the AMD chip's thread count is higher, which explains its wins in integer math and compression.

Cache layouts are also distinct. The AMD processor uses a per-core design: 64 KB L1 per core and 1 MB L2 per core, with 8 MB of shared L3. The Intel processor lists 192 KB L1 total and 2.5 MB L2 total, with 6 MB of shared L3. The AMD chip's larger total cache (with 4 MB L2 across all cores plus 8 MB L3) gives it a capacity advantage, while the Intel chip's design appears optimized for lower latency per thread.

Memory support separates the two clearly. The AMD chip uses DDR5 with a dual-channel bus and 83.2 GB/s bandwidth, plus ECC support. The Intel chip supports DDR5 and LPDDR5X but only on a single-channel bus, with 59.7 GB/s bandwidth and no ECC. The AMD chip's memory bandwidth is 39.4% higher, a significant margin for memory-sensitive workloads.

PCIe connectivity also differs. The AMD chip provides Gen 4 with 14 CPU lanes, while the Intel chip offers Gen 4 with only 6 lanes. Integrated graphics are present in both: AMD uses Radeon 740M, Intel uses Intel Xe3 Graphics with 1 Xe core.

The Verdict

The data points to the Intel Core 3 305 as the stronger overall performer. It wins 14 of 17 head-to-head tests, holds a higher average benchmark score (18,302 versus 17,614), and sits at a higher percentile (72nd versus 71st). Its 10.8% advantage across every Cinebench test indicates a per-thread efficiency lead that carries through most Passmark workloads. The largest gaps, such as 61.7% in prime number search and 41.6% in floating point math, show that the Intel chip's 6 physical cores handle compute-heavy tasks with far greater throughput than the AMD chip's 4 cores.

The AMD Ryzen 3 8300GE remains competitive in specific areas. Its 21.3% win in integer math and 5.7% win in data compression demonstrate that its 8 threads, combined with higher memory bandwidth (83.2 GB/s versus 59.7 GB/s), provide a real advantage in parallel integer workloads. The AMD chip also offers ECC memory support, which the Intel chip lacks.

Where Each One Wins

The Intel Core 3 305 is the clear choice for raw compute performance. Its wins span single and multi-threaded rendering, floating point math, physics simulation, data encryption, and prime number calculation. The 10.8% margin in Cinebench tests makes it the better processor for content creation and 3D rendering workloads. Its 41.6% advantage in floating point math and 39.2% advantage in physics suggest strong scientific and simulation performance. The 21.9% encryption win indicates better security-related throughput.

The AMD Ryzen 3 8300GE wins where thread count and memory bandwidth matter most. Its 21.3% integer math advantage and 5.7% compression win point to productivity tasks like data processing and file compression. The 2.2% random string sorting win shows a small edge in sorting operations. The AMD chip's dual-channel memory with 83.2 GB/s bandwidth versus 59.7 GB/s, combined with 8 threads versus 6, gives it an architecture suited to memory-heavy parallel integer workloads. Its ECC support also makes it more appropriate for systems requiring error-corrected memory, though this comes at the cost of a higher 35 W TDP versus 15 W for Intel.
