Where Each One Wins

AMD wins every Cinebench test in the head-to-head set, covering R15, R20, and R23 in both single-core and multi-core. AMD also wins every PassMark test except the single-thread metric. That includes data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithread, physics, and random string sorting.

Intel’s only head-to-head wins are the PassMark single-thread score and its duplicate database entry, both at 3977 against AMD’s 3605. In use-case terms, AMD’s wins span rendering, compression, encryption, physics, and integer math. Intel’s win is confined to a single PassMark single-thread workload.

Architecture Differences

The AMD Ryzen 5 7600X3D is built on Zen 4 architecture with the Raphael codename, while the Intel Core 3 305 carries the Wildcat Lake codename and the Core 3 (Wildcat Lake) generation label. AMD uses TSMC’s 5 nm process and lists 11,270 million transistors on a 71 mm² die. Intel uses Intel’s 3 nm process, and the database does not list transistor count or die size for it.

The two parts target different platforms. AMD is a desktop processor on AMD Socket AM5, while Intel is a mobile processor on Intel BGA 1516. AMD’s memory controller supports DDR5 over a dual-channel bus with 83.2 GB/s of bandwidth. Intel supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s. AMD provides 24 PCIe Gen 5 lanes, while Intel provides 6 PCIe Gen 4 lanes. AMD includes Radeon Graphics and supports ECC memory. Intel includes Intel Xe3 Graphics (1 Xe) and does not support ECC.

AMD’s cache is organized as 64 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3. Intel’s cache is listed as 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. Both processors have 6 physical cores, but AMD has 12 threads while Intel has 6 threads. Both processors are listed as active production parts, and both have locked multipliers.

Head-to-Head Benchmarks

Across the recorded head-to-head tests, AMD wins 15 and Intel wins 2. The biggest AMD margins are in PassMark physics, integer math, and prime number finding. In physics, AMD scores 2906 against Intel’s 1233, a 135.7% lead. In integer math, AMD scores 73804 against 32295, a 128.5% lead. In prime number finding, AMD scores 234 against 115, a 103.5% lead.

Random string sorting gives AMD a 94.7% lead, 34318 to 17623. Data compression gives AMD a 91.8% lead, 281665 to 146857. The multithread PassMark test shows AMD ahead by 67.5%, 25855 to 15439. Extended instructions show a 55.9% lead, 21108 to 13543. Data encryption shows a 47.4% lead, 16237 to 11019. Floating point math is the closest AMD win, 44289 to 42284, a 4.7% lead.

The Cinebench results are similarly consistent. In Cinebench R23 multi-core, AMD scores 21758 against 13123, a 65.8% lead. In Cinebench R23 single-core, AMD scores 3071 against 1852, also a 65.8% lead. Cinebench R20 multi-core is 9138 against 5511, a 65.8% lead, and Cinebench R20 single-core is 1289 against 777, a 65.9% lead. Cinebench R15 multi-core is 2193 against 1322, a 65.9% lead, and Cinebench R15 single-core is 309 against 186, a 66.1% lead.

Intel’s only head-to-head win is PassMark single-thread, where Intel scores 3977 and AMD scores 3605, giving Intel a 9.4% lead. The database records that same single-thread result twice, which accounts for Intel’s 2 wins.

The Verdict

The recorded data gives the overall advantage to AMD. AMD’s average benchmark score is 24728 against Intel’s 18302, and AMD sits in the 77th percentile of all CPUs in the database while Intel sits in the 72nd. AMD wins 15 head-to-head tests, including all Cinebench tests and nearly all PassMark tests. Intel wins 2 head-to-head entries, both representing the same PassMark single-thread score.

The Intel Core 3 305 is a 15 W mobile processor, and its recorded strength is narrow: a single-thread PassMark result 9.4% above AMD. For desktop workloads represented by Cinebench and the PassMark suite, the AMD Ryzen 5 7600X3D is the stronger part in the database. For the specific PassMark single-thread workload, the Intel part posts the higher score. The data therefore directs desktop users to AMD, while Intel’s only clear win is the PassMark single-thread metric.
