AMD Ryzen 9 270 vs Intel Core Ultra 7 270K Plus Comparison

Head-to-Head Benchmarks

The benchmark data presents a stark contrast between these two processors. The Intel Core Ultra 7 270K Plus dominates the head-to-head comparison, winning 15 of 17 recorded tests, while the AMD Ryzen 9 270 secures only 2 victories. The magnitude of Intel's wins is substantial, with most deltas exceeding 40 percent.

The largest margin comes from PassMark's find prime numbers test, where Intel scores 615 against AMD's 88, a delta of -85.7 percent. This is a workload that heavily rewards Intel's architecture. Floating point math shows a similar pattern, with Intel at 229,491 versus AMD's 60,122, a 73.8 percent gap. Data encryption also favors Intel heavily, 59,097 against 20,852, a delta of -64.7 percent.

Cinebench multicore results reinforce Intel's dominance. In Cinebench R15 multicore, Intel scores 6,656 versus AMD's 2,664, a 60 percent difference. The R20 multicore test shows Intel at 24,461 against 11,103, a 54.6 percent gap. Even in R23 multicore, which narrows the relative difference to 40.3 percent, Intel still leads with 44,253 versus 26,438.

PassMark multithread performance favors Intel at 68,574 against 29,089, a 57.6 percent delta. Integer math shows Intel at 175,986 versus 98,266, a 44.2 percent advantage. Random string sorting favors Intel at 96,945 against 42,819, a 55.8 percent gap. Extended instructions, data compression, and physics tests all show Intel ahead by margins between 55.8 and 66.4 percent.

The two AMD wins are both single-core tests, and they tell a nuanced story. In Cinebench R15 single-core, AMD scores 376 versus Intel's 354, a 6.2 percent edge. The R23 single-core result is more dramatic: AMD at 3,732 against Intel's 2,439, a 53 percent advantage. However, Cinebench R20 single-core goes the other way, with Intel at 3,453 versus AMD's 1,567, a 54.6 percent gap. PassMark single-thread also favors Intel, 5,068 against 3,784, a 25.3 percent delta. The single-core picture is thus inconsistent across test versions, with AMD winning two tests and Intel winning two others.

Where Each One Wins

The Intel Core Ultra 7 270K Plus is the clear choice for heavily threaded workloads. Every multicore benchmark in the database, whether Cinebench R15, R20, R23, or PassMark multithread, shows Intel ahead by at least 40 percent. The same applies to math-heavy tasks: integer math, floating point math, and prime number calculations all favor Intel by substantial margins. Data compression and encryption workloads also lean strongly toward Intel, with deltas of 56.3 and 64.7 percent respectively.

The AMD Ryzen 9 270 wins in specific single-core scenarios. Its Cinebench R23 single-core score of 3,732 is 53 percent higher than Intel's 2,439, which is a notable outlier given that Intel wins R20 single-core by an equally large margin. The R15 single-core result, a 6.2 percent AMD advantage, is more modest. These wins suggest that AMD's Zen 4 cores can deliver competitive single-thread performance in certain rendering workloads, even though the overall average single-thread performance in PassMark favors Intel.

For physics simulations, PassMark shows Intel at 4,064 versus AMD's 1,365, a 66.4 percent lead. This workload often correlates with gaming physics and simulation performance. The data does not include gaming-specific benchmarks, so any inference about real-world gaming must remain cautious, but the physics result points toward Intel having an advantage in simulation-heavy scenarios.

Architecture Differences

The architectural gap between these processors is substantial. The AMD Ryzen 9 270 uses Zen 4 architecture on a 4 nm TSMC process, packing 25,000 million transistors onto a 178 mm² die. It has 8 cores and 16 threads, with a base clock of 4.00 GHz and a boost clock of 5.20 GHz. The Intel Core Ultra 7 270K Plus uses Arrow Lake Refresh architecture on a 3 nm TSMC process, with 17,800 million transistors on a 243 mm² die. It offers 24 cores and 24 threads, with a base clock of 3.70 GHz and a boost clock of 5.50 GHz.

Cache configurations differ significantly. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The larger L3 cache likely contributes to Intel's strong performance in data compression and encryption tests.

Memory bandwidth also favors Intel: 115.2 GB/s versus AMD's 89.6 GB/s, both dual-channel DDR5. Intel supports ECC memory, AMD does not. PCIe connectivity differs as well, with Intel offering Gen 5 with 20 lanes versus AMD's Gen 4 with 20 lanes.

Power and thermals show a wide gap. AMD has a TDP of 45 watts, while Intel is rated at 125 watts. This suggests the AMD part is designed for mobile systems, and indeed its market segment is listed as Mobile on AMD Socket FP8. Intel targets Desktop with Socket 1851. The integrated graphics also differ: AMD uses Radeon 780M, Intel uses Arc Xe-LPG Graphics 64EU.

Production status is Active for both. Release dates differ, with AMD appearing in January 2025 and Intel in March 2026. Intel's multiplier is unlocked, AMD's is not. Intel's launch MSRP is $299.

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 7 270K Plus delivers dramatically higher throughput in almost every workload category, with average benchmark score of 93,785 versus AMD's 40,246, a 133 percent advantage. Intel sits in the 96th percentile of all CPUs, while AMD sits in the 87th.

For users running multi-threaded applications, rendering, data processing, or math-heavy simulations, the Intel part is the obvious choice. Its 24 cores and 24 threads, combined with 36 MB of L3 cache and higher memory bandwidth, produce consistent wins across all multicore tests. The smallest Intel multicore margin is 40.3 percent in Cinebench R23, which is still a decisive lead.

The AMD Ryzen 9 270 offers a different trade-off. Its 45-watt TDP and mobile socket suggest it targets laptops and compact systems where power efficiency matters. Its single-core wins in Cinebench R15 and R23 show that its Zen 4 cores remain competitive for lightly threaded workloads, but the inconsistent single-core results across test versions make it difficult to claim a universal single-thread advantage.

Intel's nearest rivals are server-class parts: the Xeon 6520P sits at parity with a 0 percent delta, the AMD EPYC 4564P is 1.5 percent ahead, and the EPYC 9175F is 1.9 percent ahead. AMD's nearest rivals include the Core i9-13905H at -0.2 percent and the Ryzen 7 7700 at 0.4 percent. This positioning reinforces that Intel's part competes with enterprise silicon, while AMD's part sits among mainstream mobile and desktop chips.

The verdict is straightforward: the Intel Core Ultra 7 270K Plus is the higher-performing processor in nearly every measured category. The AMD Ryzen 9 270 is the lower-power alternative with a mobile form factor and occasional single-core wins.
