AMD Ryzen 7 9700X vs Intel Core 3 305 Comparison

AMD Ryzen 7 9700X and Intel Core 3 305 occupy opposite ends of the computing spectrum. The AMD part is a desktop flagship with eight cores and a 65 W TDP, while the Intel chip is a mobile processor with six cores and a 15 W TDP. The recorded benchmark data shows a complete sweep: the Ryzen 7 9700X wins all 15 head-to-head tests, with margins ranging from 17% to 272%. That dominance is reflected in the aggregate scores, where the AMD part averages 37943 and the Intel part averages 18302.

Where Each One Wins

The data is unambiguous on the win split: the AMD Ryzen 7 9700X wins every recorded benchmark, and the Intel Core 3 305 has zero wins. The use-case split therefore falls entirely on the AMD side in terms of raw performance. The Ryzen 7 9700X delivers a 140.7% higher Passmark multithread score (37161 versus 15439), which translates to a decisive advantage in heavily threaded workloads like video encoding, 3D rendering, and scientific computation. The Cinebench R23 multicore result of 20485 versus 13123 confirms the same pattern, a 56.1% lead.

Single-threaded performance is closer but still favors AMD. The Passmark single-thread score of 4654 versus 3977 is a 17% advantage, and the Cinebench R23 single-core result of 2211 versus 1852 is a 19.4% lead. For everyday desktop responsiveness and lightly threaded applications, the Ryzen 7 9700X remains ahead, but the margin is far smaller than in multicore tests. The Intel Core 3 305 does have its own territory: it is a 15 W mobile chip with a 3 nm process node, making it suitable for compact, power-limited designs where the Ryzen 7 9700X, with its 65 W TDP and desktop socket, cannot physically fit. The data does not record any benchmark where the Intel chip wins, so its advantage is purely in platform characteristics, not measured performance.

Head-to-Head Benchmarks

The largest single margin in the recorded data is Passmark integer math. The AMD Ryzen 7 9700X scores 120142, and the Intel Core 3 305 scores 32295. The delta is 272%, meaning the AMD part operates at nearly three times the throughput. This is a synthetic test, but it indicates a substantial advantage in integer-heavy workloads such as compilation and database operations.

Passmark data compression shows a 197.7% lead for the AMD chip, with scores of 437140 versus 146857. This test often correlates with file archiving and compression tasks. The AMD part also leads by 160.8% in extended instructions (35318 versus 13543), which covers workloads using newer SIMD instruction sets.

The Cinebench R15 multicore test shows a 140.4% difference (3178 versus 1322), while the Passmark multithread test shows a 140.7% difference (37161 versus 15439).

The Passmark physics test (2241 versus 1233) and data encryption test (21815 versus 11019) sit in the middle, with margins of 81.8% and 98% respectively. The floating point math test shows an 86.8% lead (78999 versus 42284). The find prime numbers test shows a 67% lead (192 versus 115).

Every recorded head-to-head benchmark goes to the AMD Ryzen 7 9700X. The average benchmark score for the AMD part is 37943, placing it at the 86th percentile of all CPUs in the database. The Intel Core 3 305 has an average score of 18302, placing it at the 72nd percentile.

Specification Differences

The core and thread counts differ significantly. The AMD Ryzen 7 9700X has 8 cores and 16 threads, while the Intel Core 3 305 has 6 cores and 6 threads. The Intel chip has no hyperthreading, so its thread count equals its core count. The base clocks are far apart: the AMD part runs at 3.80 GHz, and the Intel part runs at 1.50 GHz. Boost clocks are 5.50 GHz and 4.30 GHz respectively.

The TDP difference is stark. The AMD Ryzen 7 9700X is rated at 65 W, while the Intel Core 3 305 is rated at 15 W. This reflects their different market segments: the AMD chip is a desktop part, and the Intel chip is a mobile part. The sockets are incompatible: AMD uses Socket AM5, and Intel uses BGA 1516.

Memory support differs in channel configuration. The AMD Ryzen 7 9700X uses dual-channel memory with 89.6 GB/s bandwidth, while the Intel Core 3 305 uses single-channel memory with 59.7 GB/s. Both support DDR5, but the Intel chip also supports LPDDR5X. The AMD part supports ECC memory, while the Intel part does not.

PCIe connectivity also differs. The AMD chip provides Gen 5 with 24 lanes, while the Intel chip provides Gen 4 with 6 lanes. The integrated graphics differ: AMD uses Radeon Graphics, and Intel uses Xe3 Graphics with one Xe core.

The launch MSRP for the AMD Ryzen 7 9700X is $359. The launch MSRP for the Intel Core 3 305 is $309. The AMD part has an unlocked multiplier; the Intel part does not.

Architecture Differences

The AMD Ryzen 7 9700X uses the Zen 5 architecture, codenamed Granite Ridge, built on a 4 nm process at TSMC. It has 8,315 million transistors on a 70.6 mm² die. The cache hierarchy is per-core: 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache.

The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process at Intel. The database does not record its transistor count or die size. Its cache layout is different: 192 KB of L1 total, 2.5 MB of L2 total, and 6 MB of shared L3 cache. The Intel chip uses a single-channel memory controller, which contributes to its lower memory bandwidth.

The generation field shows the AMD part as "Ryzen 7 (Zen 5 (Granite Ridge))" and the Intel part as "Core 3 (Wildcat Lake)". The AMD chip is a desktop processor from the 9000 series, while the Intel chip is a mobile processor with no series field recorded. The production status for both is listed as Active. The release dates differ: the AMD part launched on 2024-08-07, and the Intel part launches on 2026-04-15.

The process node advantage goes to Intel at 3 nm, but the AMD part compensates with a larger transistor budget and higher clock speeds. The L3 cache difference is substantial: 32 MB shared on the AMD chip versus 6 MB shared on the Intel chip. This cache advantage likely contributes to the AMD part's lead in latency-sensitive tests.

The Verdict

The benchmark data shows a clear performance hierarchy. The AMD Ryzen 7 9700X wins all 15 head-to-head tests, with the smallest margin being 17% in single-threaded Passmark and the largest being 272% in integer math. The average benchmark score of 37943 places it at the 86th percentile of all CPUs, while the Intel Core 3 305 sits at the 72nd percentile with an average of 18302.

The Intel Core 3 305 is not competitive on raw performance. Its closest rivals in the database are the Intel Core i3-14100 (average score 18318, delta -0.1%), the Intel Core 5 330 (18345, -0.2%), and the Intel Core 7 360 (18374, -0.4%). These are all within 0.4% of the Intel Core 3 305's score, indicating that it sits in a crowded field of low-power processors.

The AMD Ryzen 7 9700X, by contrast, has nearest rivals that are all within 0.4% of its score: the Intel Core i9-14901E (37911, delta 0.1%), the AMD Ryzen AI 9 HX 370 (37904, 0.1%), the Intel Core 5 211E (37829, 0.3%), and the AMD Ryzen AI Embedded P132 (37804, 0.4%). This places it in a performance tier far above the Intel Core 3 305.

The choice between these two comes down to platform constraints, not benchmark results. The Intel Core 3 305 is a 15 W mobile processor with a 3 nm process and BGA 1516 socket. It is designed for laptops and embedded systems where power draw and physical size matter more than throughput. The AMD Ryzen 7 9700X is a 65 W desktop processor with an AM5 socket, an unlocked multiplier, and dual-channel memory. It delivers over twice the average benchmark score and supports ECC memory.

For a desktop build requiring maximum performance, the data points exclusively to the AMD Ryzen 7 9700X. For a low-power mobile system, the Intel Core 3 305 offers a functional baseline, but the recorded benchmarks show it trailing in every measured category. The percentile rankings reinforce this: 86th versus 72nd among all CPUs. The performance gap is not marginal; it is structural across all workload types.
