Where Each One Wins

The benchmark data reveals a clear dichotomy in workload suitability. The AMD EPYC 9175F is the undisputed champion in integer-heavy and latency-sensitive tasks. Its wins in PassMark integer math (219800 vs 175986, a 24.9% delta), find prime numbers (741 vs 615, a 20.5% delta), and physics (9984 vs 4064, a massive 145.7% delta) indicate a processor optimized for complex logical operations and real-time simulation. The Cinebench R23 multi-core result (55923 vs 44253, a 26.4% delta) and single-core result (7895 vs 2439, a 223.7% delta) further reinforce its strength in sustained, heavy compute loads. The EPYC 9175F also leads in extended instructions (70529 vs 63506, an 11.1% delta) and data compression (867186 vs 804322, a 7.8% delta), making it the superior choice for database work, scientific computing, and rendering.

The Intel Core Ultra 7 270K Plus, conversely, dominates in floating-point mathematics and certain single-threaded tasks. Its overwhelming win in PassMark floating-point math (229491 vs 145939, a 36.4% delta) is its most significant advantage, suggesting a stronger FPU design for workloads like financial modeling or certain physics simulations. It also takes the PassMark single-thread crown (5068 vs 4256, a 16% delta) and wins in data encryption (59097 vs 42297, a 28.4% delta), indicating superior cryptographic throughput. In Cinebench R20, the Intel chip wins both multi-core (24461 vs 23487, a 4% delta) and single-core (3453 vs 3315, a 4% delta), though these margins are modest. The Intel part also edges out the AMD chip in PassMark multi-thread (68574 vs 67634, a 1.4% delta) and random string sorting (96945 vs 95783, a 1.2% delta), showing that its 24 threads can keep pace with the EPYC’s 32 threads in certain parallel tasks.

Architecture Differences

The two processors are built on different foundational designs. The AMD EPYC 9175F is a server/workstation part based on the Zen 5 architecture, codenamed Turin, part of the EPYC 9005 series. It is manufactured on a 4 nm process at TSMC, with a massive 133,040 million transistors spread across a die size of "16x 70.6 mm²". This chiplet design is typical for server processors, allowing for high core counts and massive cache. The EPYC features 16 cores and 32 threads, with an L3 cache of 512 MB shared. This enormous cache is a key differentiator, enabling the processor to hold vast datasets closer to the cores.

The Intel Core Ultra 7 270K Plus is a desktop part based on the Arrow Lake Refresh architecture, part of the Core Ultra Series 2. It is built on a more advanced 3 nm process at TSMC, with 17,800 million transistors on a monolithic 243 mm² die. It has 24 cores and 24 threads, indicating that it does not use simultaneous multithreading (SMT). Its L3 cache is a comparatively modest 36 MB shared, with a per-core L2 cache of 3 MB. The lack of SMT is a notable architectural choice, meaning the Intel chip relies on its core count and clock speed for performance. The EPYC’s per-core L1 cache is 80 KB, while the Intel’s is 192 KB, and the EPYC’s L2 is 1 MB per core versus the Intel’s 3 MB per core. The AMD chip compensates with its colossal shared L3.

Specification Differences

The most striking specification differences are in platform scope and physical attributes. The AMD EPYC 9175F uses the AMD Socket SP5 and supports 128 PCIe Gen 5 lanes (CPU only), while the Intel Core Ultra 7 270K Plus uses Intel Socket 1851 and supports 20 PCIe Gen 5 lanes. This reflects the EPYC’s role in multi-GPU and high-expansion server environments. Memory architecture differs fundamentally: the EPYC features a twelve-channel DDR5 memory bus with 576.0 GB/s bandwidth, whereas the Intel part has a dual-channel DDR5 bus with 115.2 GB/s. Both support ECC memory, but the bandwidth disparity is immense.

Clock speeds and power targets also diverge significantly. The AMD EPYC 9175F has a base clock of 4.20 GHz and a boost clock of 5.00 GHz, with a TDP of 320 W. The Intel Core Ultra 7 270K Plus has a lower base clock of 3.70 GHz but a higher boost clock of 5.50 GHz, with a TDP of just 125 W. The Intel chip is unlocked for overclocking, while the AMD is not. The EPYC offers 16 cores and 32 threads, while the Intel offers 24 cores and 24 threads. The manufacturing nodes differ (4 nm for AMD, 3 nm for Intel), and the release dates are different, with the EPYC launching on 2024-10-09 and the Intel on 2026-03-10. The EPYC has a launch MSRP of $4256, and the Intel has a launch MSRP of $299.

Head-to-Head Benchmarks

The most dramatic win for the AMD EPYC 9175F comes in Cinebench R23 single-core, where it scores 7895 against the Intel’s 2439, a staggering 223.7% delta. This is a clear indicator of the Zen 5 core’s efficiency in a power-constrained server environment. Similarly, in Cinebench R15 single-core, the EPYC scores 795 versus the Intel’s 354, a 124.6% delta. These results suggest that the EPYC’s single-thread performance is vastly superior in this specific rendering benchmark, despite the Intel’s higher boost clock of 5.50 GHz versus 5.00 GHz. The EPYC also wins big in PassMark physics, scoring 9984 versus 4064, a 145.7% delta, and in integer math with a 24.9% delta (219800 vs 175986). Its Cinebench R23 multi-core score of 55923 is 26.4% higher than the Intel’s 44253, showcasing the benefit of 32 threads and the 512 MB L3 cache.

The Intel Core Ultra 7 270K Plus’s biggest win is in PassMark floating-point math, where it scores 229491 against the EPYC’s 145939, a 36.4% delta. This is a substantial victory in a compute-heavy workload. It also wins in PassMark data encryption, scoring 59097 versus 42297, a 28.4% delta. In Cinebench R15 multi-core, the Intel chip scores 6656 against the EPYC’s 5636, a 15.3% delta, and in PassMark single-thread, it scores 5068 versus 4256, a 16% delta. The Intel part also takes narrow wins in Cinebench R20 multi-core (24461 vs 23487, a 4% delta) and single-core (3453 vs 3315, a 4% delta), as well as PassMark multi-thread (68574 vs 67634, a 1.4% delta) and random string sorting (96945 vs 95783, a 1.2% delta). These wins, while numerous, are often by smaller margins than the EPYC’s dominant victories. The data shows a processor that is a strong all-rounder for desktop workloads, with a particular edge in floating-point and cryptographic tasks.
