AMD Ryzen 7 7700X3D vs Intel Core Ultra 7 255H Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 7 255H holds the only recorded benchmark scores in the comparison. The database shows the Intel part with a comprehensive set of results across Cinebench, Geekbench, and Passmark tests, while the AMD Ryzen 7 7700X3D has no benchmark entries in the current dataset. The Intel chip records an average benchmark score of 33,537, placing it in the 83rd percentile among all CPUs. Its nearest rival in the database, the AMD Ryzen 5 240, posts an average score of 33,542, a delta of 0%, meaning the two perform essentially identically in aggregate. The Intel part also sits 0.4% ahead of both the AMD Ryzen 7 8840HS and the AMD Ryzen 5 7645HX, while trailing the Intel Core i5-12600HX by 0.5%.

Looking at the specific workloads, the Intel Core Ultra 7 255H delivers its strongest showing in Cinebench R23 multicore with a score of 9,240 points. The single-core result in that same test reaches 1,843. In Cinebench R20, the multicore score lands at 6,381 and single-core at 900. The older Cinebench R15 generation shows 1,515 multicore and 251 single-core. Geekbench results record 14,024 multicore and 2,335 single-core.

The Passmark suite provides the most granular picture. The multithread result is 30,703, while single-thread performance is 4,317. Integer math posts 77,975, floating point math 98,796, and extended instructions 23,755. Data encryption records 23,395 and data compression 298,850. Random string sorting reaches 36,058. Physics simulation scores 2,254, and the prime number finding test records 303.

The absence of AMD benchmark data means no direct head-to-head deltas can be computed from the database. The Intel chip's 83rd percentile ranking, however, places it above the median CPU in the database, whereas the Ryzen 7 7700X3D sits at the 50th percentile with an average benchmark score of zero. The Intel processor's aggregate score of 33,537 stands as the only quantified performance reference point in this pairing.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 7700X3D uses the Raphael codename, part of the 7000 series, and belongs to the Zen 4 generation. It is built on a 5 nm process at TSMC with 11,270 million transistors on a 71 mm² die. The Intel Core Ultra 7 255H uses the Arrow Lake-H codename, part of Core Ultra Series 2, and is built on a more advanced 3 nm process, also at TSMC. The Intel die size and transistor count are not recorded in the database.

Core and thread configurations differ sharply. The AMD part offers 8 cores and 16 threads. The Intel part offers 16 cores and 16 threads, meaning it doubles the core count but does not support simultaneous multithreading. Clock speeds also diverge: the AMD chip runs at a 4.00 GHz base and 4.50 GHz boost, while the Intel chip runs at a 2.00 GHz base and a much higher 5.10 GHz boost. The Intel chip's boost advantage of 0.60 GHz over the AMD chip comes alongside a much lower base clock.

Cache hierarchies are entirely different. The AMD Ryzen 7 7700X3D features 64 KB of L1 per core, 1 MB of L2 per core, and a substantial 96 MB of shared L3 cache. The Intel Core Ultra 7 255H carries 192 KB of L1 per core, 3 MB of L2 per core, and only 24 MB of shared L3. The AMD processor thus holds a 72 MB L3 advantage, a four-to-one ratio in favor of the desktop part. The Intel chip compensates with larger per-core L1 and L2 allocations.

Memory support shows both similarities and differences. Both processors use dual-channel memory buses and support ECC memory. The AMD chip supports DDR5 exclusively with a memory bandwidth of 83.2 GB/s. The Intel chip supports both DDR5 and LPDDR5X, with a higher memory bandwidth of 102.4 GB/s, a 19.2 GB/s advantage. PCIe connectivity also differs: the AMD part provides Gen 5 with 24 lanes from the CPU, while the Intel part provides Gen 5 with 20 lanes.

Integrated graphics distinguish the two. The AMD Ryzen 7 7700X3D carries Radeon Graphics, while the Intel Core Ultra 7 255H carries Arc Graphics 140T. The AMD chip is a desktop part on Socket AM5, with a 120 W TDP. The Intel chip is a mobile part on BGA 2049, with a 28 W TDP. The sockets are incompatible, and the thermal envelopes reflect their respective market segments.

Production status is Active for both. Release dates differ by over a year: the Intel chip was released on January 12, 2025, while the AMD chip is dated May 30, 2026. The AMD part has a launch MSRP of $329. The Intel part has no recorded launch MSRP. Neither processor has an unlocked multiplier, and both have part numbers recorded: 100-000002235 for AMD and SRQAN for Intel.

The Verdict

The recorded data points to the Intel Core Ultra 7 255H as the only processor with verified performance measurements. Its 83rd percentile ranking and average score of 33,537 place it in the upper tier of the database, with nearest rivals showing deltas within 0.5%. The AMD Ryzen 7 7700X3D carries no benchmark scores, an average score of zero, and a 50th percentile ranking. From the available data, the Intel chip demonstrates measurable performance across 19 benchmark entries. The AMD chip cannot be compared directly because no results exist.

The Intel processor's strengths in the database are clear. It records a multicore Cinebench R23 score of 9,240 and a Geekbench multicore score of 14,024, both substantial figures. Its Passmark multithread score of 30,703 and single-thread score of 4,317 confirm balanced performance across both heavily threaded and lightly threaded workloads. The floating point math result of 98,796 and integer math result of 77,975 show strong arithmetic throughput. Data compression at 298,850 is the standout single result in the entire dataset.

The AMD processor's case rests on specifications rather than measurements. The 96 MB of L3 cache, the 8-core 16-thread configuration, and the 5 nm TSMC process with 11,270 million transistors all point to a capable desktop design. The 120 W TDP indicates a part designed for sustained desktop workloads, unlike the Intel chip's 28 W mobile envelope. The 4.50 GHz boost clock, while lower than the Intel's 5.10 GHz, comes with a higher 4.00 GHz base clock.

The verdict from the database is straightforward: the Intel Core Ultra 7 255H is the verified performer, and the AMD Ryzen 7 7700X3D is an unverified contender. Any user requiring measured performance data can only select the Intel part. Any user willing to rely on architectural specifications must weigh the AMD chip's cache advantage and desktop orientation against the absence of recorded scores.

Where Each One Wins

The Intel Core Ultra 7 255H wins in every measured category because it is the only part with recorded benchmark results. Its Cinebench R23 multicore score of 9,240 and single-core score of 1,843 establish it as the sole data-backed performer. The Geekbench results of 14,024 multicore and 2,335 single-core reinforce that position. In Passmark tests, the Intel chip demonstrates particular strength in data compression at 298,850 and floating point math at 98,796. The single-thread score of 4,317 and multithread score of 30,703 show that neither lightly threaded nor heavily threaded workloads present a weakness in the recorded data.

The AMD Ryzen 7 7700X3D wins on architectural specifications in several areas. The 96 MB of L3 cache dwarfs the Intel chip's 24 MB, a four-to-one advantage that favors cache-sensitive workloads. The 120 W TDP suggests sustained desktop performance capability, though no measurements confirm it. The 8-core, 16-thread configuration with simultaneous multithreading differs from the Intel chip's 16-core, 16-thread design without SMT. The AMD chip also holds the higher base clock at 4.00 GHz versus 2.00 GHz, which can matter in workloads that rely on consistent clock behavior rather than burst boost.

The Intel chip wins on memory bandwidth with 102.4 GB/s versus 83.2 GB/s, a 19.2 GB/s margin. The Intel chip also wins on boost clock at 5.10 GHz versus 4.50 GHz and on process node at 3 nm versus 5 nm. The Intel chip supports a wider memory type range with both DDR5 and LPDDR5X. The AMD chip wins on PCIe lane count with 24 lanes versus 20 lanes, and on launch MSRP presence with a recorded $329 price point versus no recorded price for Intel.
