AMD Ryzen 5 5600X vs Intel Core Ultra 7 256V Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Ryzen 5 5600X and Intel Core Ultra 7 256V shows a split decision across 17 shared benchmark tests. The AMD part wins 9 tests, while the Intel part wins 8. The margins, however, tell a more complex story than the raw win count.

The Ryzen 5 5600X posts its largest victory in PassMark integer math, scoring 71,161 against 43,358 for the Core Ultra 7 256V. That is a 64.1% advantage, the single biggest delta in either direction. Data compression also heavily favors the AMD chip: 252,306 versus 184,985, a 36.4% lead. These are substantial gaps that point to a clear strength in specific computational workloads.

The Ryzen 5 5600X also wins in Cinebench R15 multicore, 1,968 versus 1,583.5, a 24.3% margin. Cinebench R23 multicore shows a 13.8% lead, with scores of 11,838 and 10,399 respectively. Geekbench multicore is closer, 9,173 versus 8,643, a 6.1% advantage. PassMark multithread follows a similar pattern at 11.9%, with scores of 21,858 and 19,530.

Other AMD wins include data encryption, 15,685 versus 13,998, a 12.1% edge. Extended instructions show an 8.6% lead, 16,991 against 15,643. Random string sorting goes to the Ryzen at 26,256 versus 22,481, a 16.8% margin.

The Intel Core Ultra 7 256V counters with its own set of victories, many of them in single-thread and floating-point work. PassMark single-thread shows 4,029 versus 3,364, a 16.5% lead. Cinebench R23 single-core is even more decisive: 1,877.5 against 1,541, a 17.9% advantage. Cinebench R15 single-core also favors Intel, 285.5 versus 254, an 11% gap.

The floating-point math test is the Intel chip's biggest win. It scores 58,576 against 39,487, a 32.6% margin. Find prime numbers goes to Intel at 192 versus 134, a 30.2% lead. Physics simulation favors Intel as well, 1,595 against 1,316, a 17.5% difference.

Geekbench single-core is essentially a tie. The Intel part scores 1,990, the AMD part 1,989, a delta of only 0.1%. This near-identical result stands in contrast to the wider single-thread margins in other tests.

Where Each One Wins

The data points to distinct workload domains for each processor. The Ryzen 5 5600X dominates in integer-heavy and multi-threaded scenarios. Its 64.1% lead in integer math and 36.4% lead in data compression suggest strong performance for tasks like database operations, file compression, and general arithmetic processing. The 24.3% and 13.8% leads in the two Cinebench multicore tests reinforce this pattern for heavily threaded rendering workloads.

The Core Ultra 7 256V excels where floating-point precision and single-thread responsiveness matter. Its 32.6% lead in floating-point math is notable, and the 30.2% edge in prime number finding indicates strong branch-heavy and recursive workloads. The 16.5% to 17.9% margins in single-thread tests across PassMark and Cinebench make it the better choice for lightly threaded applications where per-core speed is the limiting factor.

Physics simulation, which often relies on both floating-point throughput and thread scheduling, goes to Intel by 17.5%. This aligns with the floating-point advantage. Data encryption, however, stays with AMD by 12.1%, showing that not all compute-heavy tasks follow the same trend.

For mixed workloads, the average benchmark scores tell a broader story. The Ryzen 5 5600X has an average benchmark score of 21,771, while the Core Ultra 7 256V sits at 21,112. Both processors land at the 75th percentile among all CPUs in the database. The nearest rivals for the AMD chip include the AMD Ryzen 7 4800H at 21,749 (0.1% behind) and the Intel Core i7-11700 at 21,891 (0.5% ahead). For Intel, the nearest rivals include the AMD Ryzen 5 7530U at 21,133 (0.1% behind) and the AMD Ryzen 5 5600G at 21,088 (0.1% ahead).

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 5600X uses the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. It has 6 cores and 12 threads, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. The die size is 74 mm² with 4,150 million transistors. Cache is configured as 64 KB L1 per core, 512 KB L2 per core, and 32 MB L3 shared.

The Intel Core Ultra 7 256V uses the Lunar Lake architecture, part of the Core Ultra Series 2. It is built on a 3 nm process, also at TSMC. It has 8 cores and 8 threads, with a base clock of 2.20 GHz and a boost clock of 4.80 GHz. Cache differs significantly: 192 KB L1 per core, 2.5 MB L2 per core, and 12 MB shared L3. The Intel part has no listed transistor count or die size in the database.

Memory support diverges as well. The Ryzen 5 5600X supports DDR4 with dual-channel memory and a bandwidth of 51.2 GB/s. It also supports ECC memory. The Intel part lists memory support as "unknown, depends on motherboard" but still uses a dual-channel bus. ECC is not supported on the Intel chip.

PCIe connectivity shows a major gap. The AMD processor offers PCIe Gen 4 with 20 lanes from the CPU. The Intel processor provides PCIe Gen 5 with only 4 lanes from the CPU. This has implications for expansion and high-bandwidth peripherals.

The integrated graphics situation is one-sided. The Ryzen 5 5600X has no integrated graphics in the database. The Core Ultra 7 256V includes Arc 140V integrated graphics. This makes the Intel part self-contained for display output, while the AMD chip requires a discrete GPU.

The Intel part runs on a 17 W TDP, far lower than the AMD chip's 65 W TDP. The socket types differ completely: AMD Socket AM4 for the Ryzen, Intel BGA 2833 for the Core Ultra. The AMD chip has an unlocked multiplier; the Intel chip does not. Release dates are also far apart: the Ryzen launched in November 2020, the Core Ultra in September 2024.

The Verdict

The benchmark data supports a clear split based on workload priority. The AMD Ryzen 5 5600X should be chosen for multi-threaded productivity and integer-heavy tasks. It wins every multicore test in the comparison, with margins ranging from 6.1% in Geekbench multicore to 24.3% in Cinebench R15 multicore. The 64.1% lead in integer math and 36.4% lead in data compression make it the stronger option for general computing, file handling, and database-style workloads. Its 65 W TDP and unlocked multiplier also suit desktop systems where power and overclocking flexibility matter.

The Intel Core Ultra 7 256V should be chosen for single-thread responsiveness and floating-point workloads. It leads by 16.5% to 17.9% in the primary single-thread tests, and its 32.6% advantage in floating-point math is substantial. The 17 W TDP makes it far more power-efficient on paper, and the integrated Arc 140V graphics eliminate the need for a discrete GPU. Its mobile segment designation and BGA socket indicate a laptop-oriented design.

For users who need both integrated graphics and low power draw, the Intel part is the only option from this pair. For users who prioritize threaded rendering and integer compute, the AMD part is clearly ahead. The near-tie in Geekbench single-core (0.1% delta) shows that general responsiveness is comparable, but the wider margins in specialized tests point to distinct strengths. The average benchmark scores, 21,771 for AMD and 21,112 for Intel, place both at the 75th percentile, but the distribution of wins suggests choosing based on the specific tasks at hand rather than overall averages.
