AMD EPYC 9334 vs Intel Core i3-1315U Comparison

The Verdict

The AMD EPYC 9334 is the overwhelming winner in every recorded head-to-head benchmark, taking all six Cinebench comparisons by a margin of roughly 488% in each case. The data leaves no ambiguity: this is a server-class processor designed for sustained multi-threaded workloads, and it delivers accordingly. The Intel Core i3-1315U, by contrast, is a mobile part with a 15 W TDP and integrated graphics, built for efficiency and portability rather than raw compute. The verdict is simple: choose the EPYC 9334 for any workload where processing throughput is the priority, and choose the Core i3-1315U only if the platform requires a low-power mobile chip with onboard graphics. There is no benchmark in the recorded data where the Intel part wins, so the decision hinges entirely on the intended use case, not on performance comparisons.

The EPYC 9334 sits at the 70th percentile among all CPUs in the database, with an average benchmark score of 15940. Its nearest rivals include the Intel Core Ultra 5 134U, which trails by just 0.2%, and the AMD EPYC 9354P, which is 0.7% behind. The Core i3-1315U sits at the 69th percentile with an average score of 15022, placing it in the same general performance tier despite its far smaller core count and lower power envelope. That is a remarkable data point: the mobile chip, with 6 cores and 8 threads, is within a few percentage points of the server chip in average score, yet it loses every Cinebench test by a massive margin. The explanation lies in the benchmark mix, but the headline remains: for Cinebench workloads, the EPYC 9334 is in a different class entirely.

Architecture Differences

The two processors come from opposite ends of the hardware spectrum. The AMD EPYC 9334 is built on the Zen 4 architecture, codenamed Genoa, using a 5 nm process at TSMC. It packs 32 cores and 64 threads, with a base clock of 2.70 GHz and a boost clock of 3.90 GHz. The chip has 64 KB of L1 cache per core, 1 MB of L2 per core, and a substantial 128 MB of shared L3 cache. It supports DDR5 memory across a twelve-channel bus, delivering 460.8 GB/s of bandwidth, and includes ECC memory support. The EPYC 9334 uses AMD Socket SP5 and provides Gen 5 PCIe with 128 lanes from the CPU alone. It is a server and workstation part, with a TDP of 210 W.

The Intel Core i3-1315U uses the Raptor Lake architecture, specifically Raptor Lake-U, built on a 10 nm process at Intel. It has 6 cores and 8 threads, with a base clock of 1200.00 MHz and a boost clock of 4.50 GHz. Cache configuration differs significantly: 80 KB of L1 per core, 1.25 MB of L2 per core, and only 10 MB of shared L3. It supports both DDR4 and DDR5 across a dual-channel memory bus, has no ECC support, and provides Gen 4 PCIe with 8 lanes. The chip includes integrated UHD Graphics 64EU, which the EPYC 9334 lacks entirely. It uses Intel BGA 1744 and carries a TDP of just 15 W. The process node difference alone is telling: 5 nm versus 10 nm, which contributes to the EPYC's ability to house 32 cores while the Intel part manages only 6.

The transistor count also illustrates the gap. The EPYC 9334 contains 52,560 million transistors spread across a die size of 4x 72 mm², while the Core i3-1315U has no transistor count or die size listed in the database. The EPYC's 128 MB of L3 cache, twelve-channel memory bus, and 128 PCIe lanes are all server-class features that the mobile chip simply does not offer. Conversely, the Core i3-1315U has integrated graphics and a far lower TDP, making it suitable for thin-and-light laptops where power draw and heat are critical constraints.

Head-to-Head Benchmarks

The Cinebench results are lopsided in every recorded test. In Cinebench R23 multi-core, the EPYC 9334 scores 55110 against the Core i3-1315U's 9374, a delta of 487.9%. That is the largest absolute gap in the suite. In single-core R23, the EPYC scores 7780 versus 1323, a delta of 488.1%. The pattern repeats across the older Cinebench versions: R20 multi-core shows 23146 versus 3937 (487.9% delta), and R20 single-core shows 3267 versus 555 (488.6% delta). R15 multi-core shows 5555 versus 944 (488.5% delta), and R15 single-core shows 784 versus 133 (489.5% delta). Every test lands near the same percentage, which indicates a consistent per-thread performance advantage compounded by the EPYC's 32 cores versus 6.

The near-identical delta percentages across all six tests suggest that the EPYC's advantage is not merely core-count scaling but also a strong single-thread lead. The R15 single-core test, where the EPYC wins by 489.5%, is particularly telling because it involves only one core, so the gap cannot be attributed to thread count. The EPYC's Zen 4 architecture and higher base clock (2.70 GHz versus 1200.00 MHz) likely explain this, though the database does not list clock-for-clock performance. The Core i3-1315U does have a higher boost clock at 4.50 GHz, yet it still loses single-core tests decisively, which points to a fundamental architectural difference in instruction execution efficiency.

Where Each One Wins

The EPYC 9334 wins every recorded Cinebench test, both multi-core and single-core. That makes it the clear choice for rendering, scientific computing, virtualization, and any workload that scales with thread count and cache size. Its 128 MB of L3 cache, 128 PCIe Gen 5 lanes, and 460.8 GB/s memory bandwidth are all server-class features that support heavy data movement and large working sets. The 210 W TDP indicates it is designed for socketed server boards with robust cooling, not for battery-powered devices.

The Core i3-1315U has no benchmark wins in the head-to-head data, but it has attributes that matter outside of Cinebench. Its integrated UHD Graphics 64EU means it can drive a display without a discrete GPU, something the EPYC cannot do. Its 15 W TDP makes it suitable for laptops and compact systems where power efficiency is paramount. It also supports both DDR4 and DDR5, offering flexibility in memory selection, and its dual-channel bus is far simpler to implement in a mobile design. The 10 MB of L3 cache and 8 PCIe Gen 4 lanes are modest but adequate for typical mobile workloads like office productivity, web browsing, and media playback.

For users who need a server or workstation CPU, the EPYC 9334 is the only rational choice from this pair. For users who need a mobile processor with integrated graphics and low power draw, the Core i3-1315U is the functional option, despite its performance deficit in the recorded benchmarks. The data does not support any scenario where the Intel part wins on compute, but the platform requirements may still dictate its use.

The specification table highlights the fundamental divide. The EPYC 9334 is a 32-core server processor with massive cache, high memory bandwidth, and enterprise features like ECC and 128 PCIe lanes. The Core i3-1315U is a 6-core mobile chip with integrated graphics, dual-channel memory, and a 15 W power envelope. The launch MSRP reflects the positioning: the EPYC is priced at $2990, while the Core i3-1315U is $309. The data shows that the EPYC's performance advantage in Cinebench is roughly 488% across the board, which corresponds to its 32-core versus 6-core configuration and its significantly larger cache and memory bandwidth. The Core i3-1315U counters with a higher boost clock, integrated graphics, and a fraction of the power draw, making it the appropriate choice for mobile systems where the EPYC's server features are irrelevant.
