AMD Ryzen AI Max+ 392 vs Intel Core i7-14700 Comparison

AMD Ryzen AI Max+ 392 and Intel Core i7-14700 represent two distinct approaches to high-performance computing, and the recorded benchmark data shows a clear split in their respective strengths. The AMD part, a 12-core mobile processor built on the Zen 5 architecture, wins six of the eleven head-to-head tests, while the Intel desktop chip, with its 20 cores on Raptor Lake, claims five victories. The overall average benchmark scores, however, tell a different story: the Ryzen AI Max+ 392 posts an average of 90,541, placing it in the 96th percentile of all CPUs, while the Core i7-14700 averages 52,301, sitting in the 91st percentile. This discrepancy highlights that the AMD processor delivers substantially higher performance in the workloads where it leads, while Intel's wins are often narrower.

Where Each One Wins

The AMD Ryzen AI Max+ 392 demonstrates dominance in workloads that rely on large shared caches and high memory bandwidth. Its most decisive victories come in extended instructions, where it scores 45,666 against Intel's 28,388, a margin of 60.9%. This suggests the AMD part excels at workloads using specialized instruction sets, likely benefiting from its 64 MB of shared L3 cache and quad-channel LPDDR5X memory interface delivering 256.0 GB/s. The find prime numbers test shows a similar pattern, with AMD scoring 320 versus Intel's 164, a 95.1% advantage. This test is highly sensitive to integer throughput and cache latency, and the AMD architecture clearly handles it more efficiently. Physics calculations also favor AMD, with a score of 2,887 against 2,226, a 29.7% lead, indicating superior performance in simulation and physics-based computations.

The Intel Core i7-14700, conversely, wins the tests that favor its higher boost clock and larger core count. Its single-thread score of 4,236 versus AMD's 3,927, a 7.3% advantage, confirms that Intel holds the edge in lightly threaded tasks. The floating-point math test also goes to Intel, 106,716 versus 99,548, a 6.7% margin, suggesting its cores sustain higher FP throughput. Data encryption and integer math are closer contests, with Intel winning by 6.1% and 1.4%, respectively. The Intel part also wins in the broader multithread category, but this is where the data becomes nuanced: while Intel wins the single-thread test, AMD wins the dedicated multithread test with 45,231 against 40,318, a 12.2% lead. This indicates that AMD's multithreaded throughput is higher despite having fewer cores, while Intel's overall average is dragged down by its weaker performance in the workloads where AMD excels.

Architecture Differences

The two processors diverge fundamentally in design philosophy. The AMD Ryzen AI Max+ 392 uses a 4 nm process from TSMC, with a die size of 2x 70.6 mm². It packs 12 cores and 24 threads, each core with 80 KB of L1 and 1 MB of L2 cache, plus a shared 64 MB L3 pool. This large shared cache is a key differentiator, allowing all cores rapid access to frequently used data. The memory subsystem is equally distinctive: quad-channel LPDDR5X with a peak bandwidth of 256.0 GB/s. The processor also includes a Radeon 8060S integrated GPU and supports ECC memory. Its socket is AMD Socket FP11, designed for mobile platforms, and it runs with a 55 W TDP.

The Intel Core i7-14700 uses Intel's 10 nm process, with a monolithic die of 257 mm². It offers 20 cores and 28 threads, a hybrid arrangement that combines performance and efficiency cores, though the database does not specify the exact core mix. Each core has 80 KB of L1 and 2 MB of L2, but the shared L3 is only 33 MB, roughly half of AMD's allocation. Memory support is dual-channel DDR4 or DDR5, with no listed peak bandwidth. The integrated graphics are UHD Graphics 770. It uses Intel Socket 1700, is a desktop part with a 65 W TDP, and supports PCIe Gen 5 with 16 lanes. AMD's PCIe is Gen 4 with 16 lanes. The Intel chip has a higher boost clock at 5.40 GHz versus AMD's 5.00 GHz, and a lower base clock at 2.10 GHz versus 3.20 GHz.

These architectural choices directly explain the benchmark outcomes. AMD's larger shared L3 and much higher memory bandwidth benefit cache-heavy and bandwidth-bound workloads, such as extended instructions and prime number searches. Intel's higher boost clock and greater core count help in single-thread and floating-point tasks. The process node difference, 4 nm versus 10 nm, also contributes to AMD's efficiency in density and power, though the Intel part compensates with a more aggressive clock speed.

Head-to-Head Benchmarks

The largest victory in the head-to-head comparison belongs to AMD in the find prime numbers test. The Ryzen AI Max+ 392 scores 320, while the Core i7-14700 scores 164, giving AMD a 95.1% advantage. This near-doubling of score is the most extreme delta in the dataset and points to a fundamental advantage in how the AMD part handles this specific integer-heavy, latency-sensitive workload. The extended instructions test is the next most lopsided, with AMD winning 45,666 to 28,388, a 60.9% gap. This test measures performance on specialized instruction extensions, and AMD's 64 MB L3 cache likely allows larger working sets to remain on-chip.

AMD also wins the physics test by a substantial margin, 2,887 versus 2,226, a 29.7% lead. This test often stresses memory bandwidth and cache coherency, where AMD's 256.0 GB/s bandwidth and shared L3 provide clear advantages. The multithread test shows AMD ahead at 45,231 versus 40,318, a 12.2% difference. Data compression follows, with AMD scoring 554,760 against 498,198, an 11.4% win. Random string sorting also goes to AMD, 59,487 versus 54,340, a 9.5% margin.

Intel's wins are smaller but consistent. The single-thread test shows Intel at 4,236 versus AMD's 3,927, a 7.3% lead. Floating-point math gives Intel a 6.7% edge, 106,716 versus 99,548. Data encryption sees Intel at 29,601 versus 27,784, a 6.1% win. Integer math is the closest contest, with Intel winning 154,535 to 152,414, a mere 1.4% difference. These results indicate that while Intel leads in raw single-core speed and FP throughput, its advantages are modest compared to AMD's dominance in cache and bandwidth-sensitive tasks.

The overall average benchmark scores reflect this asymmetry. AMD's average of 90,541 places it 0.2% behind the Intel Xeon 654 and 0.7% behind the AMD Ryzen 9 9955HX, while sitting 2.7% ahead of the Intel Xeon w7-2575X and 3.0% ahead of the Intel Xeon 6736P. Intel's average of 52,301 is 0.2% behind the Intel Xeon Gold 5320H, 0.3% ahead of the AMD EPYC 8124P, 0.4% ahead of the Intel Core Ultra 5 235HX, and 0.7% ahead of the AMD Ryzen 9 5950X. The percentile ranks, 96th for AMD versus 91st for Intel, underscore that the AMD part competes in a higher performance tier overall.

The Verdict

The data indicates that the AMD Ryzen AI Max+ 392 is the stronger overall processor for compute-intensive, cache-sensitive, and bandwidth-heavy workloads. Its 96th percentile ranking, average score of 90,541, and wins in six of eleven tests, including a 95.1% margin in prime number finding and a 60.9% margin in extended instructions, show a clear advantage in specialized and parallel tasks. The 256.0 GB/s memory bandwidth and 64 MB shared L3 cache are the primary enablers of this performance. The Intel Core i7-14700, in the 91st percentile with an average of 52,301, retains the edge in single-threaded performance with a 7.3% lead, and in floating-point math with a 6.7% margin.
