AMD EPYC 9454 vs Intel Core Ultra 7 268V Comparison

The AMD EPYC 9454 and Intel Core Ultra 7 268V are not competitors in any conventional sense; they are designed for entirely different physical and operational environments. The data confirms this decisively: the EPYC 9454 wins all six shared head-to-head benchmarks, often by margins exceeding 300%. The Core Ultra 7 268V, however, is not a failure—it is a mobile processor built for efficiency, and the benchmark results must be interpreted through that lens. The verdict is clear: choose the EPYC 9454 for server and workstation workloads where multi-threaded throughput is paramount; choose the Core Ultra 7 268V for thin-and-light laptops where the 17W TDP is a hard constraint and integrated graphics are a necessity.

The Verdict

The AMD EPYC 9454 is the unequivocal performance king in this comparison. Its 48 cores and 96 threads deliver a Cinebench R23 multi-core score of 73,375, which is 588.8% ahead of the Intel Core Ultra 7 268V’s 10,653. This is not a close contest; it is a categorical dominance in raw compute. For any workload that scales with core count—database hosting, virtualization, scientific computing, or compilation—the EPYC 9454 is the only rational choice. Its 75th percentile ranking among all CPUs further confirms its position as a high-end part, even if its average benchmark score of 21,223 places it near rivals like the Intel Core Ultra 7 155U (21,174) and AMD Ryzen 5 7530U (21,133). That average, however, is dragged down by single-core tests; in multi-core, it is untouchable.

The Intel Core Ultra 7 268V, conversely, is a mobile chip with a 17W TDP, and the data shows it is optimized for a different set of priorities. While it loses every shared benchmark to the EPYC 9454, its standalone benchmarks reveal a competent single-thread performer: a Geekbench single-core score of 2,270 and a Passmark single-thread score of 4,051. Its 74th percentile ranking is nearly identical to the EPYC 9454’s 75th, indicating that within its own mobile segment, it is a strong performer. The verdict for the 268V is not about winning against a server chip; it is about providing adequate performance in a power-constrained envelope, which it does. Pick the 268V if you need a processor for a laptop with integrated Arc 140V graphics and a battery-friendly design. Pick the EPYC 9454 for anything that requires maximum throughput.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes. The AMD EPYC 9454 is part of the EPYC 9004 series, codenamed Genoa, and uses the Zen 4 architecture. It is fabricated on a 5 nm process at TSMC, with a stated transistor count of 52,560 million spread across a die size listed as 8x 72 mm². This is a server-class design with 48 cores and 96 threads, a base clock of 2.75 GHz, and a boost clock of 3.80 GHz.

The Intel Core Ultra 7 268V is a member of the Core Ultra Series 2, codenamed Lunar Lake, using the Lunar Lake architecture. It is built on a more advanced 3 nm process, also by TSMC, but with no transistor count or die size listed in the data. This is a mobile design with just 8 cores and 8 threads—notably, no hyperthreading—with a base clock of 2.20 GHz and a boost clock of 5.00 GHz. The higher boost clock on the Intel part suggests a design focused on bursty single-thread performance, whereas the AMD part’s lower clocks are offset by sheer core count.

Cache structures also diverge significantly. The EPYC 9454 has a 64 KB L1 cache per core, a 1 MB L2 cache per core, and a massive 256 MB shared L3 cache. The Core Ultra 7 268V has a larger 192 KB L1 per core, a 2.5 MB L2 per core, but only 12 MB of shared L3. The EPYC’s 256 MB L3 is a server-grade feature designed to hold large working sets, while the Intel part’s smaller L3 is typical for mobile efficiency. Additionally, the EPYC 9454 supports ECC memory, while the 268V does not. The EPYC also uses a twelve-channel memory bus with 460.8 GB/s bandwidth, while the 268V uses a dual-channel bus with no bandwidth figure listed.

Head-to-Head Benchmarks

The shared benchmark suite is exclusively Cinebench, and the results are lopsided. In Cinebench R15 multi-core, the EPYC 9454 scores 7,396 against the 268V’s 1,616, a delta of 357.7%. The single-core R15 test is also won by the EPYC, scoring 1,044 versus 293, a 256.3% advantage. This single-core result is surprising given the 268V’s higher 5.00 GHz boost clock, but the EPYC’s Zen 4 architecture and higher base clock of 2.75 GHz evidently deliver more instructions per clock in this legacy test.

Moving to Cinebench R20, the EPYC 9454 scores 30,817 in multi-core, a 347.5% lead over the 268V’s 6,887. The R20 single-core test shows the same 347.5% delta, with scores of 4,350 and 972 respectively. The most dramatic margin appears in Cinebench R23 multi-core, where the EPYC scores 73,375 against 10,653, a staggering 588.8% difference. The R23 single-core test shows a 439.2% lead for the EPYC, with 10,358 versus 1,921.

These numbers tell a story of absolute dominance in every shared test. The EPYC 9454 wins all six head-to-head benchmarks (winsA: 6, winsB: 0). The deltas are so large that they are not merely incremental improvements; they represent different performance tiers entirely. The 268V’s highest relative performance is in Cinebench R15 single-core, where it still loses by over 250%, indicating that even in the discipline where a mobile chip might be expected to compete, the server part’s architecture wins decisively.

The TDP difference of 290W versus 17W is the most telling metric. The EPYC 9454 consumes over 17 times the power budget of the 268V, which explains the massive performance gap but also confines it to a server chassis with robust cooling. The 268V’s integrated Arc 140V graphics and 4 PCIe lanes confirm its mobile, all-in-one design, while the EPYC’s 128 PCIe Gen 5 lanes are for connecting to enterprise storage and accelerators.

Where Each One Wins

The AMD EPYC 9454 wins in every benchmark category where both processors were tested. Its victory is absolute across Cinebench R15, R20, and R23, in both single-core and multi-core tests. The practical implication is that the EPYC 9454 is the winner for any workload that can utilize multiple cores: heavy virtualization, large-scale database transactions, 3D rendering, and scientific simulations. Its 96 threads and 256 MB L3 cache are purpose-built for these tasks. The 75th percentile ranking, while not top-tier, indicates solid standing, and its average score of 21,223 is competitive with a range of other high-end CPUs. The EPYC 9454 is the choice when performance is the only metric that matters.

The Intel Core Ultra 7 268V wins in no shared benchmark against the EPYC 9454, but its use case is entirely different. Its 17W TDP makes it suitable for fanless or low-noise mobile devices where the 290W EPYC is physically impossible to deploy. The 268V’s integrated Arc 140V graphics provide a complete package for a laptop, eliminating the need for a discrete GPU. Its standalone Passmark scores—such as 42,669 in integer math and 57,628 in floating point math—show it is no slouch for everyday tasks. The 268V wins in the categories of power efficiency, portability, and integrated graphics capability, even if those are not reflected in the head-to-head Cinebench results. For mobile productivity, media consumption, and light content creation, the 268V is the clear winner. For anything else, the EPYC 9454 is the definitive choice.
