AMD Ryzen 5 7500X3D vs Intel Core Ultra 7 270K Plus Comparison

Head-to-Head Benchmarks

The recorded data shows a comprehensive victory for the Intel Core Ultra 7 270K Plus across every single head-to-head benchmark. Of the 11 direct comparisons, Intel wins all 11, with the AMD Ryzen 5 7500X3D recording zero wins. The margins are substantial in every category, ranging from roughly 31% to 81% deficits for the AMD processor.

The largest gap appears in floating-point math, where the Intel part scores 229,491 against AMD's 43,594, a delta of 81%. This indicates the Intel processor delivers more than 5 times the floating-point throughput in this specific workload. Data encryption shows a 73.3% deficit for AMD (15,797 versus 59,097), while extended instructions trail by 67.8% (20,455 versus 63,506). Integer math shows a 59.8% gap, with scores of 70,774 versus 175,986.

Multithreaded performance follows the same pattern. The Intel processor records 68,574 in the PassMark multithread test, while AMD manages 25,047, a 63.5% difference. Random string sorting shows a 66% delta (32,999 versus 96,945), and data compression shows a 66.2% gap (271,649 versus 804,322). The find prime numbers test, often sensitive to core count and memory latency, shows Intel ahead by 64.1% (615 versus 221).

Single-thread performance is the closest category in relative terms, yet Intel still leads by 31.1%. The Intel Core Ultra 7 270K Plus scores 5,068 in PassMark single-thread, compared to 3,494 for the AMD Ryzen 5 7500X3D. Physics simulation shows a similar 31.6% delta (4,064 versus 2,779), making it the second-narrowest margin.

Average benchmark scores reinforce the hierarchy. The Intel part records an average score of 93,785, while the AMD part averages 44,573. The Intel processor sits at the 96th percentile against all CPUs in the database, whereas the AMD processor sits at the 89th percentile. The Intel chip's nearest rivals are enterprise-class parts: the Intel Xeon 6520P (delta 0%), AMD EPYC 4564P (delta -1.5%), AMD EPYC 9175F (delta -1.9%), and AMD EPYC 4565P (delta -2.1%). The AMD Ryzen 5 7500X3D, by contrast, competes with mobile and mainstream desktop parts: the Intel Core Ultra X9 388H (delta 0.2%), Intel Core i9-13950HX (delta 0.5%), AMD Ryzen AI Max 385 (delta 0.6%), and Intel Core i5-14600 (delta -0.7%).

Architecture Differences

The two processors diverge sharply in their fundamental design. The AMD Ryzen 5 7500X3D is a 6-core, 12-thread part based on the Raphael codename and Zen 4 architecture, built on a 5 nm process at TSMC. It integrates 11,270 million transistors on a 71 mm² die. The Intel Core Ultra 7 270K Plus is a 24-core, 24-thread processor with the Arrow Lake Refresh codename, fabricated on a 3 nm process, also at TSMC. It contains 17,800 million transistors across a 243 mm² die.

The core count difference is stark: Intel provides 24 cores versus AMD's 6, and Intel uses a 1:1 thread ratio while AMD doubles threads per core. Clock speeds favor Intel at the top end. The Intel part boosts to 5.50 GHz with a 3.70 GHz base clock, while the AMD part boosts to 4.50 GHz with a 4.00 GHz base clock. The AMD chip has a locked multiplier, whereas the Intel chip has an unlocked multiplier, which enables overclocking.

Cache configurations reveal different strategies. The AMD Ryzen 5 7500X3D provides 64 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3 cache. The Intel Core Ultra 7 270K Plus provides 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The AMD processor's large 96 MB L3 is its defining feature, while Intel relies on a larger per-core L1 and L2 allocation despite a smaller shared L3.

Memory bandwidth also differs. The Intel part records 115.2 GB/s of memory bandwidth, while the AMD part records 83.2 GB/s. Both support dual-channel DDR5 and ECC memory. PCIe lane counts favor AMD: 24 Gen 5 lanes (CPU only) versus Intel's 20 Gen 5 lanes (CPU only).

Integrated graphics differentiate the pair as well. AMD includes Radeon Graphics, while Intel includes Arc Xe-LPG Graphics 64EU. Power characteristics are not directly comparable in the data beyond the TDP figures: 65 watts for AMD versus 125 watts for Intel. The Intel part draws a higher thermal envelope, consistent with its larger core count and higher boost clock.

Release timing differs by several months. The AMD Ryzen 5 7500X3D was released on 2025-11-11, while the Intel Core Ultra 7 270K Plus followed on 2026-03-10. Both are listed as Active production parts for the desktop market segment. The AMD part uses AMD Socket AM5, and the Intel part uses Intel Socket 1851, so they are not interchangeable on any platform.

Where Each One Wins

The benchmark data leaves no ambiguity about workload distribution. The Intel Core Ultra 7 270K Plus wins every measured category, but the relative margins suggest where each processor is least disadvantaged.

For heavily parallel workloads, the Intel part dominates. Multithreaded rendering, data compression, encryption, and extended instruction workloads all show deltas between 63.5% and 73.3%. The floating-point math result, with an 81% deficit for AMD, indicates that compute-heavy scientific or simulation tasks strongly favor the Intel processor. The 24 cores and 3 nm process appear to deliver throughput that the 6-core AMD part cannot approach.

The AMD Ryzen 5 7500X3D comes closest in single-threaded workloads and physics simulation, with deltas of 31.1% and 31.6% respectively. These are the only two categories where the AMD deficit falls below 60%. The 96 MB of L3 cache may help in latency-sensitive single-threaded tasks, but the data shows that even there, the Intel processor's higher boost clock of 5.50 GHz provides a decisive edge.

For users constrained by the 65-watt TDP of the AMD part, the Ryzen 5 7500X3D offers a lower thermal ceiling. The data does not include power consumption measurements, so any thermal comparison must rely solely on the listed TDP figures. The AMD part also provides more PCIe lanes (24 versus 20) and a smaller die (71 mm² versus 243 mm²), which may matter for specific system configurations.

The nearest-rival data places each processor in a different competitive tier. The AMD Ryzen 5 7500X3D's average score of 44,573 places it within 0.7% of the Intel Core i5-14600 and within 0.6% of the AMD Ryzen AI Max 385. The Intel Core Ultra 7 270K Plus's average score of 93,785 places it essentially level with the Intel Xeon 6520P and within 2.1% of the AMD EPYC 4565P. This indicates that the Intel part competes with server-class silicon, while the AMD part competes with mid-range desktop and mobile processors.

The Verdict

The data from the database presents a clear hierarchy. The Intel Core Ultra 7 270K Plus outperforms the AMD Ryzen 5 7500X3D in every recorded benchmark, with average scores of 93,785 versus 44,573. The Intel part also holds a higher percentile rank (96 versus 89) and competes against server-class processors in the nearest-rival analysis.

The AMD Ryzen 5 7500X3D's advantages are limited to structural characteristics rather than measured performance. It uses a smaller die (71 mm² versus 243 mm²), carries a lower TDP (65 watts versus 125 watts), offers more PCIe lanes (24 versus 20), and provides a larger L3 cache (96 MB versus 36 MB). Its launch MSRP is $269. The Intel Core Ultra 7 270K Plus has a launch MSRP of $299.

For workloads where the 96 MB L3 cache or the 65-watt TDP is the deciding factor, the AMD processor may fit a specific system design. For raw performance across all measured categories, the Intel processor is the stronger choice. The recorded data shows no benchmark category where the AMD part wins, so any selection favoring AMD must rest on platform compatibility, thermal constraints, or the lower TDP, not on performance scores.

The Intel processor's unlocked multiplier adds flexibility for users who intend to overclock, while the AMD processor's locked multiplier removes that option entirely. The Intel part's 5.50 GHz boost clock and 24 cores give it a structural performance ceiling that the AMD part cannot match, even with its larger L3 cache. The verdict, strictly from the data, is that the Intel Core Ultra 7 270K Plus is the higher-performing processor in every measured category, while the AMD Ryzen 5 7500X3D offers a lower-TDP alternative with a larger L3 cache and more PCIe lanes.
