AMD Ryzen AI Max+ 388 vs Intel Core 3 305 Comparison

Where Each One Wins

The recorded benchmark data shows a complete dominance by the AMD Ryzen AI Max+ 388, winning all 15 head-to-head comparisons against the Intel Core 3 305. This is not a close contest by any measure. The AMD part wins across every category tested, from single-threaded tasks to heavily parallel workloads, and the margin varies considerably depending on the nature of the workload.

The AMD Ryzen AI Max+ 388 achieves its largest advantages in integer math, where it scores 109,588 against Intel's 32,295, a delta of 239.3%. This pattern suggests the AMD processor is strongly optimized for arithmetic-heavy operations, likely due to its Zen 5 architecture and the sheer number of execution resources available. Data compression shows a similar story, with AMD at 400,887 versus Intel's 146,857, a 173% advantage. These are workloads that rely heavily on both raw core count and memory bandwidth, two areas where the AMD part holds clear specification advantages.

For productivity and content creation, the Cinebench results tell a nuanced story. In Cinebench R23 multi-core, AMD scores 18,759 versus Intel's 13,123, a 42.9% lead. The single-core gap is much smaller at 5.8% (1,960 vs 1,852), indicating that the Intel Core 3 305 is reasonably competitive in lightly threaded tasks despite its much lower clock speeds and fewer cores. The Cinebench R15 multi-core test amplifies the difference to 117.2% (2,872 vs 1,322), suggesting that the AMD part scales better under shorter, bursty workloads.

The PassMark physics test, which simulates rigid body dynamics, shows AMD ahead by 49.5% (1,843 vs 1,233). Floating point math follows with a 72% lead (72,722 vs 42,284). These results indicate that the AMD processor's FPU performance is significantly stronger, which matters for scientific computing and physics simulations. The encryption workload shows an 82.3% advantage (20,092 vs 11,019), likely benefiting from the AMD's AES-NI implementation and higher memory bandwidth.

The only areas where the Intel Core 3 305 approaches parity are single-threaded integer tasks. The PassMark single-thread test shows AMD at 4,185 versus Intel's 3,977, a mere 5.2% difference. The Cinebench R23 single-core score is close as well at 5.8%. This indicates that Intel's Wildcat Lake cores are efficient at extracting performance from single-threaded code, even with a boost clock of 4.30 GHz versus AMD's 5.00 GHz. However, these narrow margins do little to offset the massive multi-core deficit.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Max+ 388 uses the Zen 5 architecture under the Strix Halo codename, built on a 4 nm process from TSMC. It contains 8 cores and 16 threads thanks to simultaneous multithreading. The Intel Core 3 305 uses the Wildcat Lake codename, built on a 3 nm process from Intel's own foundry, with 6 cores and 6 threads. Intel does not enable hyper-threading on this part, which immediately halves its thread count relative to core count.

Cache configurations diverge sharply. AMD provides 80 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. Intel offers 192 KB of L1 cache total, 2.5 MB of L2, and 6 MB of shared L3. The AMD part's L3 cache is more than five times larger, which helps explain its massive lead in data compression and integer math tests where working sets exceed the smaller cache. The per-core L2 allocation also favors AMD at 1 MB per core versus a total of 2.5 MB across 6 cores for Intel.

Memory architecture presents another major differentiator. AMD uses LPDDR5X memory over a quad-channel bus, providing 256.0 GB/s of bandwidth. Intel uses DDR5 or LPDDR5X over a single-channel bus, delivering only 59.7 GB/s. This 4.3x bandwidth advantage for AMD directly impacts multi-threaded workloads that stream data, such as the PassMark multi-thread test where AMD scores 33,486 versus Intel's 15,439, a 116.9% lead. The single-channel memory configuration is a significant bottleneck for the Intel part.

The integrated graphics differ as well. AMD ships the Radeon 8060S, while Intel offers Xe3 Graphics with one Xe core. The database does not contain graphics benchmarks, but the specification gap is substantial. Both processors support PCIe Gen 4, with AMD providing 16 lanes and Intel providing 6 lanes. AMD supports ECC memory, Intel does not. AMD's socket is FP11, Intel's is BGA 1516, meaning they are not interchangeable in any system.

Power envelopes are another clear distinction. AMD's TDP is 55 watts, while Intel's is 15 watts. This 40-watt difference explains why the AMD part can sustain higher clock speeds and larger caches, though it also means the Intel processor is better suited for passively cooled or ultra-low-power designs. The AMD processor's base clock is 3.60 GHz with a 5.00 GHz boost, while Intel runs at 1.50 GHz base and 4.30 GHz boost. The lower base clock for Intel suggests it is designed primarily for bursty workloads rather than sustained all-core operation.

Head-to-Head Benchmarks

The Cinebench R15 multi-core test delivers one of the most lopsided results, with AMD scoring 2,872 against Intel's 1,322, a 117.2% margin. This test is compute-bound and scales well with core count, so AMD's 8 cores with 16 threads versus Intel's 6 cores with 6 threads explains much of the gap. The single-core variant shows a 60.2% difference (298 vs 186), which is larger than the R23 single-core gap and suggests Intel's architecture performs relatively better under longer single-threaded loads.

Cinebench R23 multi-core narrows the gap to 42.9% (18,759 vs 13,123), indicating that the Intel part's efficiency cores or improved thermal management allow it to sustain performance better over longer rendering workloads. The single-core R23 score shows only a 5.8% difference (1,960 vs 1,852), reinforcing that Intel's single-threaded capability is genuinely competitive despite the lower boost clock.

The PassMark integer math test is the single largest margin in the entire comparison. AMD scores 109,588 versus Intel's 32,295, a staggering 239.3% delta. This workload exercises ALU throughput, branch prediction, and cache bandwidth, all areas where AMD's Zen 5 design excels. Data compression shows a 173% advantage (400,887 vs 146,857), which ties directly to the larger L3 cache and higher memory bandwidth.

Random string sorting, a test that stresses memory access patterns and pointer chasing, shows AMD ahead by 145.1% (43,196 vs 17,623). Extended instructions, which include AVX and other SIMD operations, produce a 141.6% delta (32,719 vs 13,543). These results confirm that AMD's wider execution units and better memory subsystem handle complex instruction patterns more efficiently.

The floating point math test shows a 72% lead for AMD (72,722 vs 42,284), while the physics simulation test shows 49.5% (1,843 vs 1,233). Data encryption favors AMD by 82.3% (20,092 vs 11,019), and the prime number finding test shows a 26.1% delta (145 vs 115), the smallest multi-threaded margin. The single-thread PassMark test rounds out the comparison with a 5.2% difference (4,185 vs 3,977), the smallest overall.
