AMD Ryzen 5 7600X3D vs Intel Core 7 251TE Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen 5 7600X3D and the Intel Core 7 251TE is sharply defined by workload type. The Intel part wins 12 of the 17 recorded head-to-head comparisons, while the AMD part takes 5. That split is not random: Intel dominates in multi-threaded throughput, memory-heavy operations, and floating-point math, while AMD shows its strength in single-thread responsiveness, extended instruction execution, and physics simulation.

For heavily parallel workloads, the Intel Core 7 251TE is the clear leader. It wins every Cinebench multi-core test in the database, with margins consistently near 14.7%. The same pattern appears in PassMark integer math, where Intel leads by 41.3%, and in floating-point math, where the gap widens to 48.3%. Data compression and encryption also favor Intel, with deltas of 15.8% and 26.8% respectively. The multithread aggregate score confirms the trend: Intel posts 30022 against 25855 for AMD, a 13.9% advantage.

The AMD Ryzen 5 7600X3D claims its wins in more specialized areas. The largest margin is in prime number finding, where AMD leads by 67.1%. Physics simulation also goes to AMD by 49.9%. Extended instruction throughput favors AMD by 24.4%. In single-thread PassMark, AMD edges ahead by a narrow 1% margin, with scores of 3605 versus 3568. That single-thread result is notable because Intel wins every single-core Cinebench test by roughly 14.6% to 14.7%, yet AMD manages a slight lead in the PassMark single-thread aggregate.

The overall database percentile reflects the same hierarchy. Intel sits at the 88th percentile among all CPUs, while AMD sits at the 77th. The average benchmark scores also diverge heavily: Intel records 41650, AMD records 24728. However, those aggregate figures are pulled by the different mix of tests each part was subjected to, and the head-to-head results provide the more controlled comparison.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses the Zen 4 architecture on a 5 nm TSMC process, with the Raphael codename and a 71 mm² die containing 11,270 million transistors. Intel uses the Bartlett Lake codename on a 10 nm Intel process, with a 215 mm² die. Intel does not list a transistor count in the database.

Core counts diverge sharply. AMD provides 6 cores and 12 threads. Intel provides 24 cores and 32 threads. That 4:1 core ratio explains much of the multi-thread performance gap. Clock speeds also tell different stories: AMD has a 4.10 GHz base clock and a 4.70 GHz boost clock, while Intel has a much lower 1.40 GHz base clock but a much higher 5.40 GHz boost clock. The Intel base clock is typical of a design that relies on boost behavior rather than sustained all-core base frequency.

Cache hierarchies differ in capacity and organization. AMD uses 64 KB L1 per core, 1 MB L2 per core, and a large 96 MB shared L3. Intel uses 80 KB L1 per core, 1.25 MB L2 per core, and only 36 MB shared L3. AMD's L3 advantage is substantial: 96 MB versus 36 MB, which is 2.67 times the Intel capacity. That large L3 likely contributes to AMD's wins in extended instructions and prime number finding, where working sets may fit in cache.

Memory support also differs. AMD supports DDR5 only, dual-channel, with 83.2 GB/s bandwidth. Intel supports both DDR4 and DDR5, dual-channel, with 89.6 GB/s bandwidth. Both support ECC memory. PCIe lanes differ as well: AMD offers Gen 5 with 24 CPU lanes, Intel offers Gen 5 with 16 CPU lanes. Integrated graphics differ: AMD includes Radeon Graphics, Intel includes UHD Graphics 770.

Power envelopes diverge significantly. AMD has a 65 W TDP, Intel has a 45 W TDP. That Intel figure is lower despite the much higher core count, which reflects the low base clock and the efficiency-oriented design. Socket compatibility also differs: AMD uses Socket AM5, Intel uses Socket 1700.

Head-to-Head Benchmarks

The Cinebench results are uniformly in Intel's favor. In Cinebench R15 multi-core, Intel scores 2572 against 2193, a 14.7% lead. Single-core R15 shows 362 versus 309, a 14.6% lead. R20 multi-core repeats the 14.7% margin: 10717 against 9138. R20 single-core shows 1512 versus 1289, again 14.7%. R23 multi-core has Intel at 25518 and AMD at 21758, 14.7% apart. R23 single-core has Intel at 3602 and AMD at 3071, also 14.7%. The consistency of that margin across all six Cinebench tests is striking.

PassMark results show a more varied picture. Data compression favors Intel: 334399 versus 281665, a 15.8% lead. Data encryption goes to Intel by a larger margin: 22176 versus 16237, a 26.8% lead. Floating-point math is the biggest Intel win: 85607 versus 44289, a 48.3% gap. Integer math also goes to Intel: 125739 versus 73804, a 41.3% lead. The PassMark multithread score favors Intel by 13.9%: 30022 versus 25855. Random string sorting favors Intel by 13.4%: 39643 versus 34318.

AMD's five wins are concentrated but decisive. Extended instructions: 21108 versus 16974, a 24.4% lead. Prime number finding: 234 versus 140, a 67.1% lead. Physics: 2906 versus 1938, a 49.9% lead. The two single-thread PassMark entries are identical in result: 3605 versus 3568, a 1% lead for AMD.

The physics result deserves attention. AMD leads by nearly half, which suggests the large L3 cache and the Zen 4 core design handle the physics workload efficiently. The prime number result, with a 67.1% margin, is the single largest relative difference in either direction. Extended instructions also show a clear AMD advantage, likely tied to the cache capacity.
