AMD Ryzen AI 7 345 vs Intel Core 7 240H Comparison

Head-to-Head Benchmarks

The benchmark database pits the AMD Ryzen AI 7 345 against the Intel Core 7 240H across fifteen recorded tests. Intel wins ten of these comparisons, while AMD takes five. The most decisive Intel victories come in heavily multithreaded workloads. In Cinebench R23 multi-core, Intel scores 15,764 against AMD's 11,461, a 27.3% advantage. Cinebench R15 multi-core shows a similar gap, with Intel at 2,360 versus AMD's 1,712, a 27.5% delta. PassMark physics follows the same pattern: Intel posts 1,723, AMD 1,089, leaving Intel ahead by 36.8%.

Intel's lead extends into several math-oriented PassMark tests. Floating point math shows Intel at 58,905 against AMD's 42,621, a 27.6% gap. Integer math favors Intel 80,396 to 63,475, a 21% difference. Prime number finding is particularly lopsided: Intel scores 102, AMD only 62, a 39.2% delta. Data encryption shows Intel at 15,155 versus AMD's 11,814, a 22% gap. Data compression gives Intel 271,774 against AMD's 237,484, a 12.6% margin. Even random string sorting, a memory-latency-sensitive test, goes to Intel: 28,866 versus 25,435, an 11.9% difference. PassMark multithread confirms the trend, Intel 23,975, AMD 19,927, a 16.9% gap.

AMD's five wins are narrower but consistent in single-threaded and lightweight instruction tests. Cinebench R15 single-core goes to AMD 271 to 249, an 8.8% margin. Cinebench R23 single-core has AMD at 1,818 versus Intel's 1,719, a 5.8% edge. PassMark single-thread shows AMD at 3,875 and Intel at 3,782, a 2.5% advantage. Extended instructions (SIMD-style workloads) are nearly tied: AMD 17,003, Intel 16,897, a 0.6% margin for AMD.

The pattern is clear: Intel dominates anything that scales across cores, while AMD holds a modest but real advantage in single-thread performance. The average benchmark scores reflect this overall split. Intel's average is 31,483, placing it in the 82nd percentile of all CPUs. AMD's average is 29,461, at the 81st percentile. The two processors are close in absolute standing, but their workload profiles diverge sharply.

Architecture Differences

The two mobile processors come from different design philosophies. AMD's Ryzen AI 7 345 uses the Krackan Point codename, part of the Ryzen AI 300 generation built on a mix of Zen 5 and Zen 5c cores. It has 6 cores and 12 threads. Intel's Core 7 240H uses Raptor Lake-H, from the Raptor Lake Refresh generation, with 10 cores and 16 threads. The core count difference directly explains much of Intel's multi-core dominance.

Manufacturing nodes differ substantially. AMD fabricates on a 4 nm process at TSMC. Intel uses a 10 nm process at its own foundry. The node advantage helps AMD achieve better single-core efficiency, but Intel compensates with more physical cores.

Cache hierarchies also diverge. Both have 80 KB of L1 per core. AMD provides 1 MB of L2 per core, while Intel doubles that to 2 MB per core. The L3 cache is the bigger difference: AMD has only 4 MB total, while Intel offers 24 MB shared. This larger L3 cache likely contributes to Intel's strong showing in data compression and random string sorting, workloads that benefit from keeping more working data on-chip.

Clock speeds favor Intel. Intel's base clock is 2.50 GHz with a boost of 5.20 GHz. AMD's base is 2.00 GHz with a boost of 4.60 GHz. Intel's higher boost clock helps in bursty single-threaded scenarios, though AMD still wins those tests, suggesting architectural efficiency rather than raw clock matters more.

Power envelopes differ significantly. Intel is rated at 45 W TDP, AMD at 28 W TDP. This 17 W gap allows Intel to sustain higher performance under load, but it also implies higher power consumption and cooling requirements in a laptop chassis.

Memory support and PCIe connectivity also differ. AMD supports DDR5 and LPDDR5X with dual-channel memory and 89.6 GB/s bandwidth. Intel supports DDR4 and DDR5, also dual-channel, but the database does not list its bandwidth figure. PCIe lanes favor AMD for CPU-attached devices: Gen 4 with 14 lanes versus Intel's Gen 5 with 8 lanes. AMD offers more total lanes, while Intel offers a faster generation for the lanes it has.

Integrated graphics differ as well. AMD uses the Radeon 840M, while Intel uses Iris Xe Graphics with 64 execution units. Both are integrated solutions, but the database does not provide comparative graphics benchmarks.

Where Each One Wins

Intel's Core 7 240H is the clear choice for multithreaded productivity. Its 10 cores and 16 threads, combined with a 45 W TDP and 24 MB of L3 cache, deliver decisive wins in Cinebench R23 multi-core, physics simulation, integer and floating point math, and data encryption. The 27.3% lead in Cinebench R23 multi-core over AMD suggests a substantial advantage in video rendering, 3D modeling, and other CPU-bound creative tasks. The 36.8% lead in PassMark physics indicates strong performance in physics-heavy simulations.

Intel also wins in data-heavy workloads. Data compression shows a 12.6% margin, which matters for file archiving and database operations. Data encryption at 22% ahead suggests faster handling of encrypted storage or VPN traffic. Random string sorting, up 11.9%, points to solid performance in sorting algorithms and text processing.

AMD's Ryzen AI 7 345 wins in single-threaded and lightly threaded scenarios. The 8.8% margin in Cinebench R15 single-core and 5.8% in Cinebench R23 single-core indicate better per-core efficiency, likely from the Zen 5 architecture on a 4 nm node. PassMark single-thread shows a 2.5% edge, and extended instructions are essentially tied with a 0.6% margin for AMD. These wins suggest AMD handles everyday responsiveness, web browsing, office applications, and lightly threaded legacy software with slightly better performance.

The power envelope matters here. AMD's 28 W TDP versus Intel's 45 W TDP means AMD can deliver comparable single-thread performance with lower power draw, which translates to longer battery life and thinner chassis designs. Intel's higher TDP is the price paid for its multi-core superiority.

The Verdict

The database shows two distinct design targets. The Intel Core 7 240H is the multi-core workhorse. Its 10 cores, 16 threads, 24 MB L3 cache, and 45 W TDP produce consistent, large-margin wins in every heavily threaded benchmark recorded. For users running Cinebench R23 multi-core at 15,764, PassMark physics at 1,723, or integer math at 80,396, Intel is the stronger option. The 27.3% and 27.5% multi-core Cinebench margins are not marginal; they represent a full performance tier.

The AMD Ryzen AI 7 345 wins the efficiency battle. At 28 W TDP, it matches or beats Intel in single-thread tests: Cinebench R15 single-core 271 versus 249, Cinebench R23 single-core 1,818 versus 1,719, PassMark single-thread 3,875 versus 3,782. The 4 nm TSMC node and Zen 5 architecture deliver these results with a lower power budget. For laptops prioritizing battery life and light-to-moderate workloads, AMD's profile is attractive.

The overall average benchmark score slightly favors Intel (31,483 versus 29,461), and Intel sits one percentile higher (82nd versus 81st). But the choice is not about averages; it is about workload. Intel wins 10 of 15 direct comparisons, and its wins are often large. AMD wins 5, and its wins are mostly small but consistent.

For a user whose primary tasks are multithreaded rendering, compilation, simulation, or data processing, the data clearly points to Intel. For a user who values single-thread responsiveness and lower power consumption, AMD's results are competitive and sometimes superior. The 45 W versus 28 W TDP difference is the deciding factor for chassis and cooling design, not just raw performance.
