AMD Ryzen 5 7500X3D vs Intel Core Ultra 5 245K Comparison

Where Each One Wins

The benchmark data shows a complete sweep in favor of the Intel Core Ultra 5 245K across all eleven recorded head-to-head tests, with zero wins for the AMD Ryzen 5 7500X3D. This is not a close contest; the Intel processor leads in every category, from data compression and encryption to floating point math and single-threaded performance. The magnitude of the Intel advantage varies sharply by workload, which matters for use-case planning. The smallest gap appears in the physics test, where Intel leads by only 9.8%, while the largest gap appears in floating point math, where Intel more than triples the AMD score.

For workloads that stress floating point operations, the Intel Core Ultra 5 245K is decisively stronger. Its score of 130,678 in floating point math against the AMD Ryzen 5 7500X3D's 43,594 represents a 66.6% advantage. This suggests a clear edge in scientific computing, simulations, and other FP-heavy tasks. Similarly, in data encryption, the Intel part scores 33,286 versus 15,797, a 52.5% lead, indicating significantly faster cryptographic workloads. Extended instruction set performance also favors Intel heavily, with a 45.6% delta, meaning workloads leveraging AVX or similar extensions will run much faster on the Intel chip.

In integer math, the gap narrows considerably. Intel leads with 98,524 against AMD's 70,774, a 28.2% advantage. This is still a substantial margin, but it is the second-smallest single-digit gap after physics. Single-threaded performance shows a 25.9% lead for Intel, with scores of 4,714 versus 3,494, which directly impacts responsiveness in lightly threaded applications and general desktop usability. The AMD processor does not win any category, so its role would be limited to scenarios where its other characteristics, such as power draw or platform features, are prioritized over raw benchmark performance.

The Verdict

The database records an average benchmark score of 54,053 for the Intel Core Ultra 5 245K, placing it in the 91st percentile of all CPUs. The AMD Ryzen 5 7500X3D posts an average score of 44,573, placing it in the 89th percentile. The Intel part outperforms its nearest rival, the AMD Ryzen 9 9900X3D, by 1.3%, while the AMD part trails the Intel Core i5-14600 by 0.7%. For users focused purely on measured performance, the Intel Core Ultra 5 245K is the clear choice, as it wins every benchmark in the comparison.

The AMD Ryzen 5 7500X3D does have its own positioning. It uses a 65 W TDP compared to Intel's 125 W, and it supports a smaller physical footprint with a 71 mm² die size versus Intel's 243 mm². These differences do not appear in benchmark scores but may influence platform-level decisions. However, the data cannot support a performance-based recommendation for the AMD part. The Intel processor delivers higher scores across the board, with particularly large margins in floating point, encryption, and multi-threaded workloads.

For a user deciding strictly on recorded benchmark results, the Intel Core Ultra 5 245K is the winner. It also offers an unlocked multiplier, which the AMD part lacks, and it carries a higher boost clock of 5.20 GHz versus 4.50 GHz. The AMD part has a lower launch MSRP of $269 versus Intel's $319, but this article does not weigh pricing in the verdict. The verdict from the data is unambiguous: Intel wins every measured category, and the AMD chip cannot claim a single benchmark victory.

Head-to-Head Benchmarks

The largest single margin in the head-to-head set is in floating point math. The Intel Core Ultra 5 245K scores 130,678, while the AMD Ryzen 5 7500X3D scores 43,594, a 66.6% difference. This is the kind of gap that changes project timelines for compute-heavy workloads. Data encryption shows a 52.5% lead for Intel, with 33,286 versus 15,797, which is another major gap. Extended instructions follow at 45.6%, with Intel at 37,617 and AMD at 20,455.

Multi-threaded performance, often a differentiator for productivity tasks, shows Intel ahead by 41.8%. The Intel score of 43,047 versus AMD's 25,047 means the Intel part completes parallel workloads in roughly 58% of the time the AMD part would require. Data compression shows a 40.8% lead for Intel, at 458,817 versus 271,649, and random string sorting shows a 40.1% lead, at 55,098 versus 32,999. These are all substantial, consistent advantages.

The smallest margins are in physics and integer math. Physics shows Intel ahead by 9.8%, with 3,081 versus 2,779. Integer math shows Intel ahead by 28.2%, with 98,524 versus 70,774. Prime number finding shows a 46.6% lead for Intel, at 414 versus 221. Single-threaded performance, recorded identically in two tests, shows a 25.9% lead for Intel, at 4,714 versus 3,494. Across all eleven tests, the Intel advantage ranges from 9.8% to 66.6%, with no test where the AMD part comes closer than a single-digit percentage.
