AMD EPYC 7313 vs Intel Core Ultra 5 245K Comparison

The AMD EPYC 7313 and Intel Core Ultra 5 245K target different worlds: the EPYC is a 16-core server processor with 32 threads, while the Core Ultra 5 is a 14-core desktop chip with 14 threads and a much higher boost clock. Benchmark data from the database shows a split decision: Intel wins 10 of 17 head-to-head tests, AMD wins 7, but AMD's victories include some of the largest margins, particularly in Cinebench R23 and integer math. The average benchmark score favors AMD (57399 vs 54053), and both sit near the top of the percentile rankings (92nd vs 91st). The EPYC 7313 also holds a higher percentile among all CPUs, though the Core Ultra 5 is not far behind.

Head-to-Head Benchmarks

The largest single margin in the entire comparison belongs to AMD in Cinebench R23 single-core, where the EPYC 7313 scores 4637 against the Core Ultra 5's 2132, a 117.5% advantage. This is a decisive lead, and it is accompanied by a 45% win in Cinebench R15 single-core (467 vs 322). In multi-threaded Cinebench R23, AMD again takes the win, scoring 32847 versus 25066, a 31% margin. AMD also dominates integer math, with a score of 143648 against Intel's 98524, a 45.8% lead, and physics, where it posts 3899 versus 3081, a 26.5% advantage. Data compression goes to AMD by 14.5% (525507 vs 458817), and random string sorting by 5.1% (57910 vs 55098).

Intel's biggest win is in Passmark single-thread performance, where it scores 4714 against AMD's 2402, a 49% lead. Floating-point math is also strongly in Intel's favor: 130678 versus 78748, a 39.7% margin. Intel wins the find-prime-numbers test by 25.1% (414 vs 310) and extended instructions by 11.1% (37617 vs 33430). In Cinebench R15 multi-core, Intel leads by 14% (3850 vs 3310), and in R20 multi-core and single-core it leads by 10.2% in both (15368 vs 13795 and 2169 vs 1947). Passmark multithread goes to Intel by 10.2% (43047 vs 38644), and data encryption by 4.2% (33286 vs 31881). Overall, Intel wins 10 tests, AMD 7, but the magnitude of AMD's wins in R23 and integer math is substantial.

Where Each One Wins

The benchmark results point to a clear workload split. AMD's EPYC 7313 is the stronger choice for integer-heavy tasks, physics simulation, data compression, and the Cinebench R23 rendering workload. Its 45.8% lead in integer math and 26.5% lead in physics suggest that applications relying on these operations will see a significant performance advantage. The 14.5% win in data compression and 5.1% in random string sorting further reinforce this pattern. The 31% lead in Cinebench R23 multi-core, along with the 117.5% lead in R23 single-core, indicates that the EPYC 7313 excels in modern rendering and content-creation workloads that use the R23 benchmark.

Intel's Core Ultra 5 245K, on the other hand, is the better performer in floating-point math, encryption, extended instruction sets, and prime-number finding. The 39.7% lead in floating-point math is particularly notable, as is the 49% lead in Passmark single-thread performance. The 25.1% win in find-prime-numbers and 11.1% in extended instructions show that Intel's architecture handles these specific instruction patterns more efficiently. Intel also wins the Passmark multithread test by 10.2%, though this is a smaller margin than AMD's R23 multi-core win. For desktop users who prioritize single-thread responsiveness and floating-point throughput, the Core Ultra 5 is the clear choice.

The Verdict

The data suggests that the AMD EPYC 7313 is the better processor for server and workstation workloads that involve integer math, physics, compression, and the Cinebench R23 rendering test. Its 16 cores and 32 threads, combined with a 128 MB L3 cache and eight-channel memory bandwidth of 204.8 GB/s, support these tasks effectively. The EPYC 7313 also holds a higher average benchmark score (57399 vs 54053) and a higher percentile (92 vs 91). Its nearest rivals in the database include the AMD Ryzen 9 9900X (average score 57498, delta -0.2%) and the AMD EPYC 9015 (57555, -0.3%), placing it in the upper tier of processors.

The Intel Core Ultra 5 245K is the better choice for desktop users who need high single-thread performance, floating-point throughput, and integrated graphics. It wins 10 of 17 head-to-head tests, including the Passmark single-thread and floating-point math tests, and it has a higher boost clock (5.20 GHz vs 3.70 GHz) and a lower TDP (125 W vs 155 W). Its nearest rivals include the Intel Xeon 6505P (average score 53701, delta 0.7%) and the Intel Core i7-14700F (53620, 0.8%), showing that it sits in a competitive desktop segment. The Core Ultra 5 also has an unlocked multiplier, allowing overclocking, and includes an Arc Xe-LPG Graphics 64EU integrated GPU, which the EPYC lacks.

For a server or workstation that prioritizes integer and compression workloads, the EPYC 7313 is the data-backed pick. For a desktop system focused on single-thread speed and floating-point performance, the Core Ultra 5 245K is the clear winner. The launch MSRP for the EPYC 7313 is $1083, while the Core Ultra 5 245K has a launch MSRP of $319.
