AMD EPYC 7313P vs AMD Ryzen AI 9 HX PRO 370 Comparison

The AMD EPYC 7313P and AMD Ryzen AI 9 HX PRO 370 are designed for entirely different purposes, and the benchmark data reflects that clearly. The EPYC 7313P is a server processor with 16 cores and a 155 TDP, while the Ryzen AI 9 HX PRO 370 is a mobile chip with 12 cores and a 28 TDP. The database shows the EPYC 7313P winning 13 of 15 head-to-head tests, but the Ryzen AI 9 HX PRO 370 claims a decisive victory in single-threaded performance.

The Verdict

The AMD EPYC 7313P is the pick for anyone building a server or workstation where multi-threaded throughput is the priority. Its 16 cores and 32 threads, combined with 128 MB of shared L3 cache, deliver dominant results in multi-core workloads. The data shows it leads the Ryzen AI 9 HX PRO 370 by 88.7% in Cinebench R23 multi-core and 123.5% in Passmark physics, which are massive margins for rendering and simulation tasks. It also sits at the 91st percentile of all CPUs, with an average benchmark score of 53,206.

The AMD Ryzen AI 9 HX PRO 370 is the choice for a laptop or compact system where power efficiency and single-core speed matter. Its 5.10 GHz boost clock gives it a 34.2% advantage in Passmark single-thread performance, and it achieves this with a 28 TDP, which is a fraction of the EPYC's 155 TDP. It ranks at the 90th percentile with an average score of 50,448, putting it in the same performance class as the EPYC despite having fewer cores. If you need a processor for interactive work, daily responsiveness, or any task that relies on one or two fast cores, the Ryzen AI 9 HX PRO 370 is the better fit.

Architecture Differences

The two processors come from different generations of AMD's architecture. The EPYC 7313P uses Zen 3, codenamed Milan, and is built on a 7 nm process at TSMC. The Ryzen AI 9 HX PRO 370 uses Zen 5, codenamed Strix Point, and is built on a 4 nm process, also at TSMC. This process node difference is significant: the 4 nm node allows the mobile chip to achieve higher clock speeds at a much lower power draw.

The EPYC 7313P has 16 cores and 32 threads, while the Ryzen AI 9 HX PRO 370 has 12 cores and 24 threads. The EPYC's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a large 128 MB shared L3. The Ryzen AI 9 HX PRO 370 has 80 KB of L1 per core, 1 MB of L2 per core, and only 16 MB of L3. The EPYC's massive L3 pool is clearly designed for server workloads that benefit from large data sets being cached on-die.

Memory support also diverges. The EPYC 7313P supports DDR4 with an eight-channel memory bus and a bandwidth of 204.8 GB/s. The Ryzen AI 9 HX PRO 370 supports DDR5 and LPDDR5X on a dual-channel bus with 89.6 GB/s of bandwidth. The EPYC's eight-channel memory subsystem gives it more than twice the memory bandwidth, which is critical for multi-threaded server tasks. Both processors support ECC memory, and neither has an unlocked multiplier. The EPYC has no integrated graphics, while the Ryzen AI 9 HX PRO 370 includes a Radeon 890M iGPU.

FAQ

Q: Which processor is faster in single-core performance?

A: The Ryzen AI 9 HX PRO 370 is significantly faster. In Passmark single-thread, it scores 4,003 versus the EPYC's 2,634, a 34.2% advantage. This is consistent with its higher 5.10 GHz boost clock compared to the EPYC's 3.70 GHz.

Specification Differences

The core difference is the market segment: the EPYC 7313P is for servers and workstations, while the Ryzen AI 9 HX PRO 370 is for mobile devices. The EPYC has 16 cores and 32 threads, while the Ryzen has 12 cores and 24 threads. Base clocks are 3.00 GHz for the EPYC versus 2.00 GHz for the Ryzen, but boost clocks reverse the trend: 3.70 GHz for the EPYC and 5.10 GHz for the Ryzen.

The TDP is a striking contrast: 155 watts for the EPYC versus 28 watts for the Ryzen. The EPYC uses the AMD Socket SP3 platform, while the Ryzen uses AMD Socket FP8. The process nodes differ: 7 nm for the EPYC (Zen 3, Milan) versus 4 nm for the Ryzen (Zen 5, Strix Point). The EPYC has a die size of 4x 81 mm², while the Ryzen has a single 233 mm² die. Transistor count is listed for the EPYC at 16,600 million, but no figure is recorded for the Ryzen.

Cache configurations are distinct. The EPYC uses 64 KB L1 and 512 KB L2 per core with 128 MB shared L3. The Ryzen uses 80 KB L1 and 1 MB L2 per core with 16 MB L3. Memory support: DDR4 with eight channels for the EPYC, DDR5/LPDDR5X with dual channels for the Ryzen. Memory bandwidth is 204.8 GB/s versus 89.6 GB/s. PCIe lanes also differ: 128 lanes for the EPYC versus 16 lanes for the Ryzen, both Gen 4. The EPYC has no integrated graphics, while the Ryzen includes the Radeon 890M.

Head-to-Head Benchmarks

The EPYC 7313P dominates the multi-core tests. In Cinebench R23 multi-core, it scores 34,952 versus 18,520 for the Ryzen, a 88.7% lead. Cinebench R15 multi-core shows a smaller gap at 10.8% (3,522 vs 3,178). Passmark multithread gives the EPYC a 23.3% win (41,121 vs 33,349). The EPYC is also far ahead in Passmark physics, scoring 4,229 against 1,892, a 123.5% margin. In Passmark find prime numbers, the EPYC wins by 164.1% (346 vs 131), its largest victory.

The EPYC also leads in memory and encryption workloads. Passmark data encryption shows a 71.9% advantage (35,727 vs 20,788). Passmark data compression is 31% higher (528,167 vs 403,113). Passmark random string sorting goes to the EPYC by 43% (62,596 vs 43,767). Integer math favors the EPYC by 21.3% (145,558 vs 120,016), and floating point math by 11.9% (82,260 vs 73,493). Extended instructions also go to the EPYC by 16.4% (32,784 vs 28,165).

The Ryzen AI 9 HX PRO 370 wins the single-thread tests. Passmark single-thread shows 4,003 versus 2,634, a 34.2% advantage. This is the same result for both Passmark single-thread and single-thread fields, which are listed as separate entries but show identical scores. Interestingly, the EPYC wins Cinebench R15 single-core by 60.8% (497 vs 309) and Cinebench R23 single-core by 147.7% (4,934 vs 1,992), which contradicts the Passmark result. This suggests the Cinebench tests may favor the EPYC's architecture differently, but the Passmark single-thread test clearly favors the Ryzen's higher boost clock.

Where Each One Wins

The EPYC 7313P wins in every multi-threaded and memory-intensive workload. Its 16 cores, 32 threads, and 128 MB L3 cache make it the clear choice for server virtualization, database processing, scientific computing, and any task that scales with core count. The 88.7% lead in Cinebench R23 multi-core and 123.5% lead in Passmark physics indicate it is ideal for rendering, simulation, and heavy computational loads. The 71.9% advantage in data encryption and 31% in data compression point to strong performance in server-side data processing and storage workloads. The eight-channel memory bus and 204.8 GB/s bandwidth give it a major edge in memory-bound applications.

The Ryzen AI 9 HX PRO 370 wins in single-thread performance, as shown by its 34.2% Passmark single-thread advantage. This makes it the better choice for everyday desktop responsiveness, office work, and applications that are not highly parallelized. Its 28 TDP and 5.10 GHz boost clock mean it can deliver fast performance in a mobile form factor without needing a large cooling solution. The integrated Radeon 890M GPU also gives it a capability the EPYC lacks entirely, making it suitable for a compact system where a discrete GPU is unnecessary. For a laptop user who values snappy single-core performance and long battery life, the Ryzen AI 9 HX PRO 370 is the clear winner. For a server administrator who needs maximum multi-core throughput, the EPYC 7313P is the only choice.
