AMD Ryzen 7 8745HX vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive overall victory for the AMD Ryzen 7 8745HX, which takes 9 of the 11 recorded comparisons. The most dramatic divergence appears in integer math, where AMD scores 100328 against Intel's 32295, a lead of 210.7%. This result indicates a fundamental difference in per-core throughput and multi-threaded scaling that carries through most of the test suite.

Data compression shows a similar pattern. The AMD part records 363759, while the Intel Core 3 305 manages 146857, a 147.7% advantage for AMD. Random string sorting follows with AMD at 44494 versus Intel's 17623, a 152.5% gap. These workloads rely heavily on memory bandwidth and cache behavior, and the recorded totals suggest the Ryzen 7 8745HX has substantially more headroom in both areas.

The multithread test puts AMD at 31517 against Intel's 15439, a 104.1% difference. That is exactly double the throughput, a result consistent with the core and thread counts recorded in the specifications. Extended instructions show the same 104.1% delta, with AMD scoring 27638 and Intel 13543. Data encryption is closer in percentage terms but still one-sided: AMD posts 21840 versus 11019, a 98.2% gap.

Floating point math favors AMD by 46.6%, with scores of 61972 and 42284. Prime number finding is a narrower win for AMD, 159 to 115, a 38.3% delta. Physics simulation also goes to AMD, 1681 to 1233, a 36.3% margin.

The single bright spot for the Intel Core 3 305 is in single-thread performance. Intel scores 3977 against AMD's 3879, a 2.5% edge. That is a modest lead, but it does show that Intel's architecture, running at a lower base clock of 1.50 GHz against AMD's 3.60 GHz, can still win a purely serial workload. The boost clocks tell part of the story: Intel reaches 4.30 GHz, while AMD tops out at 5.10 GHz, yet the Intel part still wins the single-thread test, which points to a higher instructions-per-clock efficiency in that specific scenario.

The average benchmark score reinforces the overall picture. AMD's average sits at 60104, while Intel's is 18302. That places the Ryzen 7 8745HX in the 92nd percentile of all CPUs in the database, versus the 72nd percentile for the Core 3 305. The nearest rivals for AMD include the AMD Ryzen 9 7945HX at 60099, the Intel Core i9-14900F at 60008, the AMD Ryzen 9 7945HX3D at 59641, and the Intel Xeon Gold 6338T at 60572. The delta percentages are small, ranging from -0.8% to 0.8%, meaning the Ryzen 7 8745HX sits in a tightly packed group of very strong desktop and mobile processors.

Intel's nearest rivals tell a different story. The Core 3 305 sits alongside the Intel Core i3-14100 at 18318, the Intel Core 5 330 at 18345, the Intel Core 7 360 at 18374, and the AMD Ryzen 5 2600E at 18230. The deltas here are also tiny, between -0.4% and 0.4%, but the absolute level is far below AMD's cluster. In short, the Ryzen 7 8745HX competes in a performance tier roughly three times higher than the Core 3 305 on average.

The Verdict

The data points to a clear split in intended use cases. The AMD Ryzen 7 8745HX is the stronger processor in nearly every measured category, and its average benchmark score of 60104 places it among top-tier desktop and mobile chips. The 92nd percentile ranking means it outperforms the vast majority of CPUs in the database. Anyone selecting between these two strictly on performance data should choose the AMD part without hesitation.

The Intel Core 3 305 has one measurable strength: single-thread performance. Its 3977 score edges out AMD's 3879, and its 72nd percentile ranking is still respectable. But the Intel part trails badly in multithreaded, memory-heavy, and math-oriented workloads. The 104.1% gap in multithread performance, the 210.7% gap in integer math, and the 147.7% gap in data compression are not marginal differences; they represent a different performance class altogether.

The recorded data also shows where each chip sits relative to its own competitive set. The Ryzen 7 8745HX trades blows with the AMD Ryzen 9 7945HX and Intel Core i9-14900F, with deltas under 1%. The Core 3 305, by contrast, sits alongside the Intel Core i3-14100 and AMD Ryzen 5 2600E, a much lower tier. For workloads that benefit from multiple cores, high memory bandwidth, or heavy integer operations, the AMD Ryzen 7 8745HX is the only rational pick. For lightly threaded tasks where single-core speed is the sole criterion, the Intel Core 3 305 holds a narrow but real edge.

Specification Differences

The two processors diverge sharply in core configuration. The AMD Ryzen 7 8745HX has 8 cores and 16 threads. The Intel Core 3 305 has 6 cores and 6 threads, meaning it lacks simultaneous multithreading entirely. Clock speeds also differ substantially: AMD's base clock is 3.60 GHz with a boost of 5.10 GHz, while Intel's base is 1.50 GHz with a boost of 4.30 GHz. Thermal design power reflects this: the AMD part is rated at 55 watts, the Intel part at 15 watts.

Memory support is another major split. AMD uses dual-channel DDR5 with a memory bandwidth of 83.2 GB/s. Intel supports DDR5 and LPDDR5X but only in single-channel mode, with a bandwidth of 59.7 GB/s. Neither processor supports ECC memory. PCIe connectivity also differs: AMD offers Gen 5 with 28 lanes (CPU only), while Intel offers Gen 4 with 6 lanes (CPU only).

The integrated graphics units are different as well. AMD pairs the CPU with a Radeon 610M. Intel includes Intel Xe3 Graphics with 1 Xe core. The AMD processor has an unlocked multiplier, while the Intel part is locked. The sockets are incompatible: AMD uses Socket FL1, Intel uses BGA 1516.

Cache hierarchies diverge in both size and organization. AMD's L1 cache is 64 KB per core, L2 is 1 MB per core, and L3 is 32 MB shared. Intel's L1 is 192 KB total, L2 is 2.5 MB total, and L3 is 6 MB shared. The total L3 advantage for AMD is more than fivefold.

Architecture Differences

The AMD Ryzen 7 8745HX is built on Zen 4 architecture with the codename Dragon Range. It belongs to the 8000 series and is fabricated on a 5 nm process at TSMC. The transistor count is recorded at 6,570 million, with a die size of 71 mm². This is a high-core-count mobile design aimed at performance notebooks.

The Intel Core 3 305 uses the Wildcat Lake codename and belongs to the Core 3 generation. It is fabricated on a 3 nm process at Intel's own foundry. The smaller process node gives Intel a potential density advantage, but the recorded data shows no transistor count or die size for this part, so a direct comparison on that basis is not possible from the database.

The architecture differences explain much of the benchmark behavior. AMD's Zen 4 design with 16 threads and 32 MB of shared L3 cache provides the resources needed for the large multithreaded and memory-bandwidth-sensitive wins. Intel's Wildcat Lake, with 6 threads and only 6 MB of L3, is a much leaner design that still manages to win the single-thread test, likely due to a strong per-core design and the 3 nm process.

The release dates in the database place the AMD Ryzen 7 8745HX at April 22, 2025, and the Intel Core 3 305 at April 15, 2026. Both are listed as Active in production status and target the Mobile market segment. The Intel part has a recorded launch MSRP of $309, while the AMD part has no launch MSRP recorded. The part numbers are 100-000001851 for AMD and SAE3L for Intel.
