AMD Ryzen 7 PRO 5755G vs Intel Core 3 305 Comparison

# AMD Ryzen 7 PRO 5755G vs Intel Core 3 305

The AMD Ryzen 7 PRO 5755G and Intel Core 3 305 occupy opposite ends of the desktop-to-mobile spectrum, yet both target active production systems in 2026. The recorded data shows a clear split: AMD wins 7 of the 11 head-to-head PassMark tests, while Intel counters with a strong single-thread showing and a surprising prime-number advantage. The Ryzen 7 PRO 5755G posts an average benchmark score of 49,196 against 18,302 for the Core 3 305, placing the AMD part at the 90th percentile of all CPUs versus the 72nd percentile for Intel. Those headline gaps, however, do not tell the full story, as the Intel chip's efficiency-class design delivers wins in workloads where the AMD part struggles.

Where Each One Wins

The AMD Ryzen 7 PRO 5755G dominates in heavily parallel, data-intensive workloads. It wins passmark_data_compression by 101.4%, integer math by 179.5%, random string sorting by 86%, multithread by 54.5%, data encryption by 76.5%, extended instructions by 51.3%, and floating point math by 20.1%. These are tasks that scale with core count, thread count, and cache capacity, all areas where the 8-core, 16-thread AMD design holds a structural edge.

The Intel Core 3 305 wins the remaining four tests: find prime numbers by 49.6%, physics by 17.1%, single-thread by 15.4%, and the duplicate single-thread test by the same margin. The prime-number result stands out because it is the largest Intel victory in percentage terms, and it suggests a per-core efficiency advantage in integer-heavy, low-parallelism loops. The physics test, which typically reflects gaming-related CPU physics simulation, also favors Intel despite the AMD part having more cores. The single-thread win at 3,977 versus 3,366 confirms Intel's higher per-core performance in lightly threaded scenarios.

The use-case split is therefore straightforward: AMD for compression, encryption, multithreaded encoding, and general productivity; Intel for single-thread responsiveness, physics simulation, and prime-number sieving workloads. The 7-to-4 win count favors AMD, but the Intel victories are concentrated in the areas where many real-time applications spend most of their time.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 PRO 5755G uses the Zen 3 architecture on TSMC's 7 nm process, with a Cezanne codename and a 180 mm² die containing 10,700 million transistors. It fits into AMD Socket AM4 and runs at a base clock of 3.80 GHz with a boost clock of 4.60 GHz, all within a 65 W TDP. The cache layout is per-core: 64 KB L1 per core, 512 KB L2 per core, and a 16 MB shared L3 pool. Memory support is DDR4 over a dual-channel bus delivering 51.2 GB/s, and the CPU exposes Gen 3 PCIe with 16 lanes.

The Intel Core 3 305 uses the Wildcat Lake codename on Intel's own 3 nm process, a significantly more advanced node. It is a mobile part with a 15 W TDP, soldered into Intel BGA 1516, and runs at a much lower base clock of 1.50 GHz but boosts to 4.30 GHz. The core count drops to 6 cores and 6 threads, with no simultaneous multithreading. Cache is organized differently: 192 KB L1, 2.5 MB L2, and 6 MB shared L3. Memory support is DDR5 and LPDDR5X over a single-channel bus, yet the recorded bandwidth is 59.7 GB/s, higher than the AMD part's dual-channel DDR4 figure. PCIe is Gen 4 with 6 CPU lanes.

Process node alone explains part of the single-thread delta. Intel's 3 nm process enables a higher boost clock relative to base, and the newer memory standard provides more bandwidth per channel. The AMD part compensates with 8 cores, 16 threads, and 16 MB of L3, which is 10 MB more shared cache than Intel's 6 MB. The absence of SMT on Intel means the 6 cores handle exactly 6 threads, whereas AMD's 8 cores handle 16 threads, a 2.67x thread-count advantage. The integrated graphics also differ: AMD uses Radeon Vega 8, while Intel uses Xe3 Graphics with 1 Xe core.

Head-to-Head Benchmarks

The largest delta in the entire comparison is passmark_integer_math, where AMD scores 90,270 against 32,295 for Intel, a 179.5% advantage. This test rewards both core count and thread scheduling, and the Ryzen 7 PRO 5755G's 16 threads nearly triple the Intel part's integer throughput. The second-largest gap is data compression at 101.4% (295,730 versus 146,857), where the AMD part's larger L3 cache and higher memory bandwidth per channel combine to process data faster. Random string sorting follows at 86% (32,771 versus 17,623), again favoring the AMD cache hierarchy.

Data encryption shows a 76.5% AMD lead (19,450 versus 11,019), reflecting the advantage of more AES-capable cores and threads. Extended instructions come in at 51.3% (20,487 versus 13,543), and multithread at 54.5% (23,858 versus 15,439). Floating point math is the closest AMD win at 20.1% (50,778 versus 42,284), indicating that the Intel part's FP units are relatively strong per core, but the AMD aggregate still prevails.

Intel's wins are narrower in absolute percentage but meaningful. The single-thread test shows Intel at 3,977 versus AMD's 3,366, a 15.4% margin. This aligns with the boost clock difference: Intel reaches 4.30 GHz versus AMD's 4.60 GHz, yet Intel still wins, implying a higher instructions-per-clock on the 3 nm Wildcat Lake design. The physics test goes to Intel at 1,233 versus 1,022, a 17.1% edge, which suggests better latency handling in a workload that does not scale linearly with core count. The prime-number test is the outlier: Intel scores 115 versus AMD's 58, a 49.6% Intel advantage. This is a single-threaded integer loop where the AMD Zen 3 core appears to lose substantial ground, possibly due to branch prediction or division unit differences, though the recorded data does not specify microarchitectural causes.

The Verdict

The recorded data supports a clear division of roles. The AMD Ryzen 7 PRO 5755G is the stronger multithreaded processor, with a 54.5% multithread lead, a 101.4% compression lead, and a 179.5% integer math lead. Its 90th percentile ranking and average score of 49,196 place it in the company of the AMD Ryzen 9 7900 (49,228, within 0.1%) and the Intel Core i5-14600KF (49,394, 0.4% higher), while sitting just above the Intel Core Ultra 5 245 (48,995, 0.4% lower). For database-style workloads, content creation, or any parallel batch processing, the AMD part is the clear choice.

The Intel Core 3 305 is the efficiency and single-thread specialist. Its 15 W TDP, 3 nm process, and 6 MB shared L3 deliver a 15.4% single-thread win and a 49.6% prime-number win despite having 10 fewer threads. Its average score of 18,302 places it within 0.1% of the Intel Core i3-14100 (18,318) and 0.2% of the Intel Core 5 330 (18,345), making it a mid-range mobile option. The 72nd percentile ranking reflects its position well below the AMD part in overall throughput.

Users who prioritize responsiveness in single-threaded applications, physics simulation, or low-power mobile operation should favor the Intel part. Users who need maximum throughput in compression, encryption, integer math, or multithreaded rendering should choose the AMD part. The data does not support a single universal winner; the correct choice depends entirely on the workload distribution.
