AMD Ryzen 5 240 vs Intel Core Ultra 7 270K Plus Comparison

Head-to-Head Benchmarks

The benchmark data presents a complete sweep. The Intel Core Ultra 7 270K Plus wins all 15 head-to-head comparisons, with no benchmark victory for the AMD Ryzen 5 240. The margin is substantial across every workload category, from single-threaded tests to heavily parallelized rendering.

The largest single gap appears in PassMark's find prime numbers test. Intel scores 615 against AMD's 70, a delta of -88.6%. This test is particularly sensitive to raw integer throughput and cache behavior, and the result indicates a fundamental performance-class difference between these two processors.

In Cinebench R23 multi-core, the Intel part delivers 44,253 points, while the AMD Ryzen 5 240 produces 13,013. That is a 70.6% advantage for Intel. The older Cinebench R15 multi-core test shows a similar pattern: 6,656 versus 2,078, a delta of -68.8%. This consistency across two generations of the Cinebench suite confirms that the multi-core gap is not an artifact of a single test version.

Single-core performance also favors Intel, though by a smaller margin. In Cinebench R23 single-core, Intel scores 2,439 versus AMD's 1,742, a 28.6% difference. The PassMark single-thread test shows 5,068 versus 3,675, a 27.5% delta. The Cinebench R15 single-core result is closer in relative terms: 354 versus 270, a 23.7% gap. Even in the least favorable comparison for Intel, the advantage remains above 23%.

Floating-point math is another area of decisive separation. PassMark floating point math scores 229,491 for Intel and 45,301 for AMD, a delta of -80.3%. Integer math shows a smaller but still large gap at -58.4%, with Intel at 175,986 and AMD at 73,189. The extended instructions test, which measures SIMD and specialized instruction throughput, gives Intel 63,506 against AMD's 20,201, a 68.2% difference.

Data compression and encryption workloads follow the same trajectory. PassMark data compression scores 804,322 for Intel versus 267,963 for AMD, a 66.7% delta. Data encryption shows Intel at 59,097 and AMD at 15,849, a 73.2% gap. Random string sorting, a memory-latency-sensitive test, gives Intel 96,945 versus AMD's 32,385, a 66.6% difference.

The PassMark multi-thread test aggregates several of these workloads into a single score. Intel records 68,574, AMD records 22,658, a 67% delta. The physics test, which simulates rigid-body physics, shows Intel at 4,064 and AMD at 1,060, a 73.9% gap.

The average benchmark score tells the same story. The Intel Core Ultra 7 270K Plus averages 93,785 across all recorded benchmarks, while the AMD Ryzen 5 240 averages 33,542. The Intel part sits in the 96th percentile among all CPUs in the database, while the AMD part sits in the 84th percentile.

The Verdict

The data supports a clear conclusion: the Intel Core Ultra 7 270K Plus is the faster processor in every measured workload. The 15-0 win count is unambiguous. No benchmark in the database shows the AMD Ryzen 5 240 ahead on any metric.

The Intel part's nearest rivals in the database are server-class processors: the Intel Xeon 6520P (delta 0%), the AMD EPYC 4564P (delta -1.5%), the AMD EPYC 9175F (delta -1.9%), and the AMD EPYC 4565P (delta -2.1%). This positioning places the Core Ultra 7 270K Plus in a performance tier far above the Ryzen 5 240, whose nearest rivals are the Intel Core Ultra 7 255H (delta 0%), the AMD Ryzen 7 8840HS (delta -0.4%), the AMD Ryzen 5 7645HX (delta -0.4%), and the Intel Core i5-12600HX (delta 0.5%).

The AMD Ryzen 5 240 is a mobile processor, while the Intel Core Ultra 7 270K Plus is a desktop processor. The market segments differ, and the performance class differs accordingly. The Ryzen 5 240's 84th percentile ranking is respectable for its category, but the Core Ultra 7 270K Plus operates in a different tier entirely.

For users comparing these two specifically, the benchmark results indicate that the Intel part dominates in both lightly threaded and heavily threaded applications. The single-core delta of 27.5% to 28.6% means even applications that rely on one or two threads will run noticeably faster on the Intel processor. The multi-core deltas of 67% to 70.6% mean workloads that scale across many cores will finish in a fraction of the time.

The Intel Core Ultra 7 270K Plus carries a launch MSRP of $299.

Where Each One Wins

The AMD Ryzen 5 240 does not win any benchmark category in the recorded data. Its role in a comparison is therefore defined by its characteristics rather than its performance victories.

The Ryzen 5 240 is a 45 W TDP mobile processor. It uses the AMD Socket FP8 and is built on TSMC's 4 nm process. Its market segment is mobile, which means it is designed for laptops and compact systems where power draw and heat dissipation are constrained. The processor integrates a Radeon 760M graphics unit, which provides display output and light graphics acceleration without a discrete GPU.

The Intel Core Ultra 7 270K Plus, by contrast, is a desktop processor with a 125 W TDP. It uses Intel Socket 1851 and is built on TSMC's 3 nm process. Its integrated graphics, an Arc Xe-LPG Graphics 64EU unit, is present but the desktop segment implies it will typically be paired with a discrete graphics card.

The use-case split is therefore structural. The Ryzen 5 240 belongs in thin-and-light mobile systems where its 45 W TDP and 4 nm process keep power consumption low. The Core Ultra 7 270K Plus belongs in desktop systems where its 125 W TDP, 24 cores, and 36 MB of L3 cache can be fully utilized.

In terms of platform features, the Intel part supports ECC memory, while the AMD part does not. The Intel part also supports PCIe Gen 5 with 20 lanes, while the AMD part supports PCIe Gen 4 with 20 lanes. The memory bandwidth figures differ: 115.2 GB/s for Intel, 89.6 GB/s for AMD, though both use dual-channel DDR5.

The Ryzen 5 240's multiplier is locked, while the Core Ultra 7 270K Plus has an unlocked multiplier. The "K Plus" designation in the Intel naming convention typically indicates overclocking capability, and the unlocked multiplier field confirms this.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen 5 240 uses the Zen 4 architecture, with the codename Hawk Point. The Intel Core Ultra 7 270K Plus uses the Arrow Lake Refresh codename, under the Core Ultra Series 2 family.

The manufacturing processes both come from TSMC, but at different nodes. The AMD part uses a 4 nm process, while the Intel part uses a 3 nm process. The transistor counts differ substantially: the AMD Ryzen 5 240 contains 25,000 million transistors, while the Intel Core Ultra 7 270K Plus contains 17,800 million. The die sizes also differ, with the AMD part at 178 mm² and the Intel part at 243 mm².

Cache hierarchies are organized differently. The AMD Ryzen 5 240 has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel Core Ultra 7 270K Plus has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. The larger per-core L1 and L2 allocations on the Intel part, combined with more than double the L3 cache, help explain its advantage in cache-sensitive workloads.

The core and thread counts reflect different design philosophies. The AMD part uses 6 cores with simultaneous multithreading, yielding 12 threads. The Intel part uses 24 cores and 24 threads, meaning it does not rely on simultaneous multithreading to reach its thread count. The Intel part's higher core count gives it a structural advantage in multi-threaded benchmarks.

The integrated graphics differ in both brand and configuration. AMD uses a Radeon 760M, while Intel uses an Arc Xe-LPG Graphics 64EU. Both provide integrated display output, but the benchmark data does not include graphics performance comparisons.

The PCIe interfaces differ by generation. The AMD part uses Gen 4 with 20 lanes, while the Intel part uses Gen 5 with 20 lanes. The newer PCIe generation on the Intel part provides higher bandwidth for compatible devices.
