AMD EPYC 9274F vs Intel Core i5-1334U Comparison

The AMD EPYC 9274F and Intel Core i5-1334U occupy opposite ends of the computing spectrum, and the benchmark data reflects that chasm. The EPYC 9274F is an absolute powerhouse in every head-to-head test, while the i5-1334U is a low-power mobile part. This analysis will break down the exact performance deltas, architectural roots, and use cases that define these two very different processors.

Head-to-Head Benchmarks

The data is unambiguous: the AMD EPYC 9274F wins all six head-to-head benchmark comparisons, with margins that range from substantial to overwhelming. In Cinebench R15 multi-core, the EPYC 9274F scores 6338 against the i5-1334U’s 1569, a 304% advantage. The single-core R15 test tells a similar story: 894 versus 241, giving AMD a 271% lead. These are not close calls; they are generational and class-level differences.

The gap widens further in newer Cinebench versions. In Cinebench R20 multi-core, the EPYC 9274F hits 26411, while the i5-1334U manages only 4638 — a 469.4% difference. The single-core R20 result is nearly identical in percentage terms: 3728 versus 654, a 470% lead for AMD. This consistency across single and multi-threaded tests suggests the EPYC’s advantage is not merely core count but also raw per-thread throughput.

The most lopsided result appears in Cinebench R23 multi-core, where the EPYC 9274F scores 62884 against the i5-1334U’s 8641. That is a 627.7% margin, the largest of any test. Even in R23 single-core, the EPYC’s 8877 dwarfs the i5’s 1727 by 414%. The pattern is clear: the EPYC 9274F does not just outperform the i5-1334U; it outperforms it by factors of 3 to 7, depending on the workload. The i5-1334U’s only available extra benchmarks (PassMark tests) were not part of the head-to-head set, so no comparison exists outside Cinebench.

The Verdict

The verdict is straightforward. The AMD EPYC 9274F is the superior processor for any compute-intensive task, based purely on the Cinebench results. It wins every single benchmark by a massive margin, with its smallest lead being 271% in R15 single-core and its largest being 627.7% in R23 multi-core. Anyone needing maximum rendering speed, scientific computation, or heavy multi-threaded workloads should choose the EPYC 9274F without hesitation.

However, the Intel Core i5-1334U is not without its own domain. Its 15W TDP and mobile BGA 1744 socket make it a viable option for battery-powered laptops where the EPYC’s 320W TDP is physically impossible to support. The data does not show the i5 winning any benchmark, but it does show a processor designed for efficiency over raw speed. The i5-1334U also includes integrated Iris Xe Graphics 80EU, which the EPYC lacks entirely, making it self-sufficient for basic display output. For a user who needs a functioning laptop with decent CPU performance and no discrete GPU, the i5-1334U is the only choice of these two. For anyone building a server or workstation, the EPYC 9274F is the only rational pick.

Architecture Differences

The architectural divide between these two CPUs is vast. The AMD EPYC 9274F is built on the Zen 4 architecture, codenamed Genoa, using a 5 nm process from TSMC. It packs 24 cores and 48 threads, with a base clock of 4.05 GHz and a boost clock of 4.30 GHz. The chip is massive, containing 52,560 million transistors across an 8x 72 mm² die configuration. It uses AMD Socket SP5 and supports twelve-channel DDR5 memory with a bandwidth of 460.8 GB/s, plus ECC memory for reliability. PCIe support is Gen 5 with 128 lanes.

In contrast, the Intel Core i5-1334U is based on Raptor Lake, specifically Raptor Lake-U, using Intel’s 10 nm process. It has 10 cores and 12 threads, with a base clock of 1300.00 MHz and a boost clock of 4.60 GHz. Despite the higher boost clock, it cannot match the EPYC’s sustained performance. The i5 supports both DDR4 and DDR5 memory over a dual-channel bus, but no memory bandwidth figure is provided. It lacks ECC support and offers only Gen 4 PCIe with 8 lanes. The i5 does include integrated Iris Xe Graphics 80EU, a feature absent from the EPYC.

Cache hierarchies differ significantly. The EPYC provides 64 KB L1 per core, 1 MB L2 per core, and a massive 256 MB shared L3 cache. The i5 offers 80 KB L1 per core, 1.25 MB L2 per core, and only 12 MB shared L3. The EPYC’s 256 MB L3 is over 20 times larger, which helps explain its dominance in multi-threaded workloads that benefit from large shared pools of fast memory. The i5’s smaller cache is typical for a mobile part designed to conserve power and die area.

Where Each One Wins

The AMD EPYC 9274F wins in every measured category from the head-to-head data. Its smallest victory is a 271% margin in Cinebench R15 single-core, and its largest is a 627.7% margin in R23 multi-core. This makes it the clear winner for rendering, video encoding, 3D modeling, scientific simulations, and any workload that scales with core count. The 24-core, 48-thread configuration, combined with 256 MB of L3 cache and twelve-channel DDR5 memory, positions it as a server or workstation powerhouse. The data also shows it wins single-core tests by 271% to 470%, meaning even lightly-threaded applications will run dramatically faster on the EPYC.

The Intel Core i5-1334U wins no benchmark in the head-to-head set, but it has qualitative advantages not captured in Cinebench. Its 15W TDP makes it suitable for fanless or passively-cooled laptops, whereas the EPYC’s 320W TDP requires substantial cooling infrastructure. The i5’s integrated Iris Xe Graphics 80EU provides display output without a discrete GPU, a critical feature for mobile systems. Its support for both DDR4 and DDR5 memory gives system designers flexibility, and its smaller 10 nm process (Intel’s node) is more appropriate for power-constrained environments. The i5’s higher boost clock of 4.60 GHz suggests it can deliver short bursts of speed, but the sustained multi-core results show it cannot hold a candle to the EPYC.

Specification Differences

The two processors differ in nearly every specification. The AMD EPYC 9274F has 24 cores and 48 threads, while the Intel Core i5-1334U has 10 cores and 12 threads. The EPYC’s base clock is 4.05 GHz versus the i5’s 1300.00 MHz, though the i5 boosts higher at 4.60 GHz versus 4.30 GHz. TDP is a massive differentiator: 320W for the EPYC versus 15W for the i5. Sockets are incompatible: AMD Socket SP5 for the EPYC, Intel BGA 1744 for the i5.

Memory support differs fundamentally. The EPYC uses twelve-channel DDR5 with 460.8 GB/s bandwidth and ECC support. The i5 uses dual-channel DDR4 or DDR5, with no ECC support and no listed bandwidth. PCIe capabilities also diverge: the EPYC offers Gen 5 with 128 lanes, while the i5 offers Gen 4 with 8 lanes. The EPYC has no integrated graphics; the i5 has Iris Xe Graphics 80EU. Cache sizes are vastly different, with the EPYC’s 256 MB L3 dwarfing the i5’s 12 MB. Process nodes differ as well: 5 nm TSMC for the EPYC versus 10 nm Intel for the i5. The EPYC contains 52,560 million transistors; the i5’s transistor count is not listed. The EPYC is a server/workstation part released on 2022-11-09, while the i5 is a mobile part released on 2023-01-03. The EPYC’s launch MSRP is $3060, and the i5’s launch MSRP is $340. Both processors are locked (multiplier unlocked: false), and both are currently active in production.
