AMD Ryzen 7 7700X3D vs Intel Core Ultra 7 270HX Plus Comparison

Where Each One Wins

The benchmark data splits these two processors into entirely different usage categories. The Intel Core Ultra 7 270HX Plus dominates nearly every measurable workload, while the AMD Ryzen 7 7700X3D has no recorded benchmark wins in the database. The Intel part sits at the 93rd percentile of all CPUs, with an average benchmark score of 61,834, placing it alongside desktop flagship parts like the Intel Core i9-13900KF (61,841, 0% delta) and the Intel Core i9-13900K (61,766, 0.1% delta). The AMD Ryzen 7 7700X3D holds only the 50th percentile with an average score of zero, meaning the database contains no recorded performance measurements for it. This makes the comparison lopsided in practical terms: the Intel chip has data, the AMD chip does not.

The Intel part wins in all recorded categories: multi-threaded rendering, single-thread performance, memory bandwidth, and PassMark compute workloads. The Cinebench R23 multi-core score of 41,913 demonstrates sustained all-core throughput, while the single-core score of 5,917 indicates strong per-thread responsiveness. The PassMark multi-thread score of 48,270 and the floating-point math score of 163,567 further confirm that this processor is built for parallel compute. The AMD processor, lacking any recorded scores, cannot claim wins in any category within this database, so any workload selection between the two must rely on the Intel data alone.

Architecture Differences

The two chips come from fundamentally different design philosophies. The AMD Ryzen 7 7700X3D uses the Raphael codename and belongs to the Ryzen 7 family built on Zen 4 architecture. It is manufactured on a 5 nm process at TSMC, using 11,270 million transistors on a 71 mm² die. The Intel Core Ultra 7 270HX Plus uses the Arrow Lake-HX Refresh codename and belongs to the Core Ultra Series 2 family built on Arrow Lake-HX architecture. Intel's chip is manufactured on a 3 nm process at TSMC, using 17,800 million transistors across a 243 mm² die, a substantially larger physical footprint.

Core counts differ dramatically. The AMD chip provides 8 cores and 16 threads, while the Intel chip provides 20 cores and 20 threads, with no hyper-threading on the Intel side. The AMD processor is a desktop part on AMD Socket AM5, rated at 120 W TDP, with a base clock of 4.00 GHz and a boost clock of 4.50 GHz. The Intel processor is a mobile part on Intel BGA 2114, rated at 55 W TDP, with a base clock of 2.40 GHz and a boost clock of 5.30 GHz. The Intel chip's higher boost clock and 3 nm process help it reach higher single-thread scores despite the lower base clock.

Cache hierarchies reflect their different workloads. The AMD chip uses 64 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3 cache, typical for a desktop gaming-focused design. The Intel chip uses 192 KB of L1 per core, 3 MB of L2 per core, and only 30 MB of shared L3 cache. The Intel part compensates with a larger per-core L1 and L2 allocation, while the AMD part relies on a much larger L3 pool.

Memory support also diverges. Both support DDR5 and dual-channel memory, but the Intel chip has a higher theoretical memory bandwidth at 102.4 GB/s versus 83.2 GB/s for the AMD chip. The AMD processor supports ECC memory, the Intel processor does not. PCIe connectivity differs as well: the AMD chip provides Gen 5 with 24 lanes (CPU only), while the Intel chip provides Gen 5 with 20 lanes (CPU only). The AMD chip includes Radeon Graphics as integrated graphics, while the Intel chip uses Arc Xe-LPG Graphics with 64 execution units.

The AMD processor launched on 2026-05-30 with a launch MSRP of $329. The Intel processor launched earlier on 2026-03-16 with no recorded launch MSRP. The AMD part has a locked multiplier, while the Intel part has an unlocked multiplier, which allows user overclocking on the Intel side. Production status is Active for both.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries between these two processors, and the AMD Ryzen 7 7700X3D has no individual benchmark scores at all. The Intel Core Ultra 7 270HX Plus, by contrast, has a full suite of Cinebench and PassMark results. The Cinebench R23 multi-core score of 41,913 and single-core score of 5,917 provide the clearest picture of its capability. In Cinebench R20, the Intel chip scores 17,603 multi-core and 2,485 single-core. In Cinebench R15, it scores 4,224 multi-core and 596 single-core.

PassMark results reinforce the same pattern. The Intel chip scores 122,449 in integer math, 163,567 in floating-point math, 39,283 in extended instructions, and 493,179 in data compression. It scores 37,813 in data encryption, 60,020 in random string sorting, and 482 in find prime numbers. The single-thread PassMark score is 4,764, and the multi-thread PassMark score is 48,270. The physics score is 3,843.

Because the AMD chip has no recorded scores, there are no exact deltas to compute between the two. The nearest rival data for the Intel chip shows how close it sits to desktop flagship parts: the Intel Core i9-13900KF averages 61,841 (0% delta), the Intel Core i9-13900K averages 61,766 (0.1% delta), the Intel Core i9-13900T averages 61,723 (0.2% delta), and the Intel Xeon 636 averages 61,360 (0.8% delta). This places the Intel Core Ultra 7 270HX Plus within a fraction of a percent of a top-tier desktop i9, despite being a mobile-class part with a 55 W TDP.

The absence of AMD benchmark data means the only quantitative verdict available is that the Intel chip outperforms the AMD chip in every recorded metric, simply because the AMD chip has no recorded metrics. The single-core advantage for the Intel chip, shown by the 5,917 Cinebench R23 single-core score, suggests strong per-thread performance, while the 41,913 multi-core score suggests sustained all-core capability.

The Verdict

From the recorded data, the Intel Core Ultra 7 270HX Plus is the only processor in this comparison with measurable performance, and it delivers flagship-level results. Its 93rd percentile ranking and average benchmark score of 61,834 place it in the same performance class as the Intel Core i9-13900KF, which scores 61,841, and the Intel Core i9-13900K, which scores 61,766. The Intel chip achieves this with a 55 W TDP, a 3 nm process, and 20 cores. The AMD Ryzen 7 7700X3D has no recorded benchmark scores and sits at the 50th percentile, which means the database contains no evidence of its performance.

Given the data, the Intel chip is the clear choice for any workload that requires measured performance. The AMD chip's strengths, such as its 96 MB of L3 cache and desktop socket, are not reflected in any benchmark results in the database. The Intel chip also offers an unlocked multiplier, a higher boost clock of 5.30 GHz, and wider memory bandwidth at 102.4 GB/s. The AMD chip offers ECC memory support and a lower launch MSRP of $329, but those features do not translate into recorded performance in this database.

The AMD chip is a desktop processor with a 120 W TDP and 8 cores, while the Intel chip is a mobile processor with a 55 W TDP and 20 cores. The recorded data does not show any scenario where the AMD chip wins, because no scores exist for it. Buyers choosing between these two parts, based strictly on the database, would select the Intel Core Ultra 7 270HX Plus for any processing task.
