AMD Ryzen AI 5 340 vs Intel Core i7-11700K Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between the AMD Ryzen AI 5 340 and the Intel Core i7-11700K. Intel secures 12 of the 17 head-to-head wins, but AMD’s five victories are concentrated in areas that reveal architectural strengths. The overall average benchmark scores are nearly identical — the AMD Ryzen AI 5 340 posts 25,981 against the Intel’s 25,812, a delta of just 0.7% in AMD’s favor. This near-parity in aggregate obscures the dramatic per-test divergences.

The Intel Core i7-11700K dominates multi-threaded rendering workloads. In Cinebench R23 multicore, Intel scores 20,666 versus AMD’s 12,532, a 39.4% advantage. The gap narrows in Cinebench R15 multicore, where Intel leads 2,082 to 1,915, an 8% margin. Geekbench multicore shows Intel ahead 10,521 to 9,165, a 12.9% difference. These results track with Intel’s 8-core/16-thread configuration against AMD’s 6-core/12-thread layout, though the magnitude of the Cinebench R23 deficit is striking — AMD trails by nearly two-fifths.

Single-core performance tells a more nuanced story. The Intel chip wins Cinebench R15 single-core by 17.5% (294 versus 242.6) and Cinebench R23 single-core by 34.3% (2,917 versus 1,915.5). Yet in Geekbench single-core, AMD flips the result, scoring 2,140 against Intel’s 1,974 — an 8.4% win. PassMark single-thread confirms AMD’s edge: 3,683 versus 3,390, an 8.6% advantage. The pattern suggests Intel’s older Rocket Lake architecture retains an advantage in certain legacy single-threaded workloads, while AMD’s Zen 5 design excels in modern, branch-heavy instruction streams.

PassMark’s specialized workloads reinforce Intel’s general-purpose strength. Data compression heavily favors Intel: 322,689 versus 229,796, a 28.8% margin. Data encryption follows with Intel leading 15,638 to 11,470, a 26.7% gap. Extended instructions yield a 28.4% Intel advantage (22,964 versus 16,440). Integer math shows Intel ahead 86,390 to 63,078, a 27% margin, while floating-point math favors Intel by 21.8% (51,119 versus 39,967). Random string sorting is Intel’s largest win: 36,755 versus 24,970, a 32.1% difference. PassMark multithread adds another Intel win, 24,408 to 19,506, a 20.1% margin.

AMD’s remaining wins are narrower but consistent. PassMark find prime numbers sees AMD score 72 against Intel’s 66, a 9.1% edge. PassMark physics favors AMD 1,095 to 1,039, a 5.4% margin. These two wins, alongside the single-thread results, point to AMD’s efficiency in latency-sensitive and physics-simulation tasks. The data shows AMD’s Zen 5 cores deliver higher instructions-per-clock in specific scenarios, even when disadvantaged by core count and clock speed.

Where Each One Wins

For multi-threaded content creation, the Intel Core i7-11700K is the clear choice. The data shows Intel leading by 39.4% in Cinebench R23 multicore and by 20.1% in PassMark multithread. Render farms, video encoding, and 3D modeling workloads that scale across cores will see substantial throughput advantages on the Intel platform. Its data compression lead of 28.8% also positions it well for archival and database workloads that compress large datasets.

The Intel chip’s dominance in integer math (27% lead) and extended instructions (28.4% lead) makes it suitable for scientific computing and financial modeling that rely on heavy arithmetic. The 26.7% encryption advantage suggests better suitability for security-focused tasks like disk encryption and VPN throughput.

The AMD Ryzen AI 5 340 wins where single-thread responsiveness and physics simulation matter. Its 8.6% PassMark single-thread lead and 8.4% Geekbench single-core advantage indicate snappier application launches and better performance in lightly-threaded interactive workloads. The 5.4% physics win, combined with the 9.1% prime-number finding edge, points to strength in engineering simulations and mathematical modeling that depend on tight loops.

For mobile users, AMD’s 28-watt TDP versus Intel’s 125 watts makes the Ryzen AI 5 340 the only realistic option for battery-powered systems. The Intel chip’s desktop socket (Intel Socket 1200) and end-of-life status further restrict its deployment scenarios. The AMD chip’s active production status and mobile FP8 socket align it with current laptop designs.

Specification Differences

The core configurations diverge significantly. The AMD Ryzen AI 5 340 packs 6 cores and 12 threads, while the Intel Core i7-11700K offers 8 cores and 16 threads. Clock speeds also differ: AMD runs a 2.00 GHz base with 4.80 GHz boost, Intel runs 3.60 GHz base with 5.00 GHz boost. Intel’s higher clocks contribute to its Cinebench wins, while AMD’s lower base clock reflects its mobile power envelope.

Memory support separates the two clearly. AMD supports DDR5 and LPDDR5X with 89.6 GB/s bandwidth. Intel supports only DDR4 with 51.2 GB/s bandwidth. This 38.4 GB/s difference gives AMD a memory bandwidth advantage that helps in certain data-intensive tasks, though Intel’s benchmark wins show other factors dominate.

Cache layouts differ per-core. Both share 80 KB L1 per core. AMD’s L2 is 1 MB per core versus Intel’s 512 KB per core. Intel compensates with 16 MB shared L3 versus AMD’s 8 MB L3. The larger shared L3 on Intel aids multi-threaded workloads that reuse common data.

The TDP gap is substantial: 28 watts for AMD versus 125 watts for Intel. Socket types reflect their markets — AMD Socket FP8 for mobile, Intel Socket 1200 for desktop. PCIe lanes also differ: AMD provides Gen 4 with 16 lanes, Intel provides Gen 4 with 20 lanes. Neither supports ECC memory. Intel’s multiplier is unlocked; AMD’s is not.

Integrated graphics differ as well. AMD ships Radeon 840M, Intel ships UHD Graphics 750. Production status separates them further — AMD is active, Intel is end-of-life. Intel’s launch MSRP was $399; AMD has no listed launch MSRP.

Architecture Differences

The AMD Ryzen AI 5 340 uses Zen 5 architecture on the Krackan Point codename, built on a 4 nm TSMC process. Intel’s Core i7-11700K uses Rocket Lake architecture on a 14 nm Intel process. The process node difference is stark — 4 nm versus 14 nm — explaining AMD’s dramatically lower TDP despite similar performance in some tests.

AMD’s generation is Ryzen AI 300 (Zen 5 / Zen 5c), indicating a hybrid core design. Intel’s generation is Core i7 (Rocket Lake-S), a monolithic desktop design. The die size for AMD is 195 mm²; Intel’s die size is not listed. AMD’s foundry is TSMC; Intel uses its own fabs.

The cache architecture reflects the hybrid approach. AMD’s 1 MB L2 per core supports higher per-thread throughput, while Intel’s 512 KB L2 per core with 16 MB shared L3 favors shared-data workloads. AMD’s 8 MB L3 is half of Intel’s, yet AMD still wins several single-threaded tests — evidence that Zen 5’s core design compensates for less cache.

Both support PCIe Gen 4, but Intel offers 4 more lanes (20 versus 16). Memory support diverges generationally — AMD is DDR5/LPDDR5X, Intel is DDR4. This aligns with their release dates: AMD’s 2025 launch versus Intel’s 2021 launch. The 4 nm process allows AMD to integrate Radeon 840M graphics and achieve 89.6 GB/s memory bandwidth while maintaining a 28-watt TDP.

Intel’s unlocked multiplier on the 11700K permits overclocking, a feature absent on the locked AMD mobile part. The architecture differences ultimately explain the benchmark split: Intel’s wider core count and higher clocks dominate throughput tests, while AMD’s newer Zen 5 cores win efficiency-sensitive and single-thread modern workloads.
