AMD Ryzen AI 7 345 vs Intel Xeon Phi 7210 Comparison

The AMD Ryzen AI 7 345 and Intel Xeon Phi 7210 represent two radically different approaches to computing, separated by a decade of architectural philosophy. The data shows a lopsided contest in most conventional workloads, but the Xeon Phi holds distinct advantages in specific data-heavy tasks. This analysis breaks down exactly where each chip dominates and why.

Head-to-Head Benchmarks

The most decisive victory for the AMD Ryzen AI 7 345 comes in single-threaded performance. In the PassMark single-thread test, the AMD scores 3875 against the Intel’s 460, a staggering delta of 742.4%. This gap is mirrored in Cinebench R23 single-core, where AMD’s 1818 beats Intel’s 876 by 107.5%. The story is similar in Cinebench R15 single-core: 271 versus 88, a 208% advantage.

Multi-core results are more nuanced. The AMD wins Cinebench R23 multicore with 11461 versus 6210, a 84.6% lead. In Cinebench R15 multicore, the AMD’s 1712 crushes the Intel’s 625 by 173.9%. The PassMark multithread test shows a 172.7% win for AMD (19927 vs 7306). Despite the Intel having 64 cores and 256 threads against AMD’s 6 cores and 12 threads, the AMD’s modern architecture delivers far superior throughput in these rendering workloads.

The Intel Xeon Phi 7210 fights back in three specific PassMark tests. Its biggest win is in data compression, scoring 332960 against AMD’s 237484, a 28.7% advantage. It also wins integer math with 84874 versus 63475, a 25.2% lead. Finally, it edges out AMD in extended instructions: 18359 versus 17003, a 7.4% margin.

Other notable AMD wins include data encryption (11814 vs 3455, up 241.9%), physics (1089 vs 198, up 450%), and find prime numbers (62 vs 10, up 520%). The AMD also dominates floating-point math by 45.2% (42621 vs 29356) and random string sorting by 184% (25435 vs 8956).

Architecture Differences

The fundamental divide is in process node and transistor budget. The AMD Ryzen AI 7 345 is built on TSMC’s 4 nm process, while the Intel Xeon Phi 7210 uses Intel’s 14 nm node. This explains the massive efficiency and clock speed differences. The AMD runs at a base clock of 2.00 GHz and boosts to 4.60 GHz. The Intel’s base clock is 1300.00 MHz (1.30 GHz) with a boost of 1500.00 MHz (1.50 GHz). The AMD’s higher clocks, combined with newer microarchitecture, are the primary reason for its dominance in single-threaded tasks.

Core counts tell the opposite story. The Intel packs 64 cores and 256 threads into a 215 W TDP. The AMD offers just 6 cores and 12 threads within a 28 W TDP. This makes the Intel a massively parallel processor on paper, but the benchmark data reveals that raw core count does not translate to wins in most real tests.

Cache hierarchies differ significantly. The AMD has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3 cache. The Intel provides 32 KB of L1 per core and 512 KB of L2 per core, with no L3 cache listed. The AMD’s larger per-core caches and shared L3 help its single-thread performance, while the Intel’s smaller caches are a bottleneck in latency-sensitive tasks.

Memory support is another clear split. The AMD uses DDR5 and LPDDR5X memory on a dual-channel bus, delivering 89.6 GB/s of bandwidth. The Intel uses DDR4, with no memory bus or bandwidth figures provided. The AMD also features integrated Radeon 840M graphics, while the Intel has no integrated graphics. The Intel does support ECC memory, which the AMD lacks.

The AMD is a mobile processor on the AMD Socket FP8, part of the Ryzen AI 300 generation (Zen 5 / Zen 5c) with the Krackan Point codename. The Intel is a server/workstation part on Intel Socket 3647, based on the Knights Landing architecture. The Intel’s process node is 14 nm, and it has 8,000 million transistors. The AMD’s manufacturing details list no transistor count.

The Verdict

From the benchmark data, the AMD Ryzen AI 7 345 is the better processor for the vast majority of users. It wins 12 of the 15 head-to-head tests, including every Cinebench test and the PassMark single-thread test by an enormous margin. Its performance in encryption (241.9% ahead), physics (450% ahead), and prime number finding (520% ahead) makes it the clear choice for general computing, mobile workstations, and any mixed workload.

The Intel Xeon Phi 7210 is a specialist. Its wins in data compression (28.7% ahead), integer math (25.2% ahead), and extended instructions (7.4% ahead) point to a chip designed for specific high-throughput data processing tasks. If your work involves heavy data compression or integer-heavy calculations that can be parallelized across many threads, the Intel’s 256 threads might offer an edge in those narrow scenarios. However, the Intel’s massive power draw (215 W TDP vs 28 W) and its poor showing in nearly every other benchmark make it a hard recommendation.

The data indicates that the AMD’s architectural efficiency, higher clock speeds, and modern memory support outweigh the Intel’s core-count advantage. The AMD’s 81st percentile ranking among all CPUs matches the Intel’s 81st percentile, but the AMD achieves that with far fewer resources. For most builders, the AMD offers a balanced, high-performance package. The Intel is for niche, data-centric workloads where its specific strengths outweigh its weaknesses.
