AMD Ryzen Embedded V2546 vs Intel Core i3-1315U Comparison

The database tells a lopsided story here: the Intel Core i3-1315U wins 14 of the 17 recorded head-to-head benchmarks against the AMD Ryzen Embedded V2546, despite being the lower-power part. The V2546 fights back only in three PassMark workloads, all of them memory-adjacent: data compression, data encryption, and extended instructions. Both chips sit at the 69th percentile versus all CPUs in the database, so this is a comparison between two mid-pack performers where the differences come down to architecture and platform features rather than raw tier.

Where Each One Wins

The i3-1315U dominates pure compute. It sweeps every Cinebench test, by margins that are remarkably consistent: 14.1 percent in R15 multi-core (944 vs 827), 14.2 percent in R23 multi-core (9374 vs 8207), and roughly 14 percent across the single-core tests as well. Those uniform deltas point to a genuine per-clock and instruction-throughput advantage, not a workload fluke. The gap widens dramatically in PassMark's synthetic math tests: 45.7 percent in floating point (27012 vs 18534), 22.5 percent in integer math (37644 vs 30739), 60.1 percent in physics (706 vs 441), and 86.4 percent in find prime numbers (41 vs 22). The single-thread split is the most brutal number on the page: 3380 vs 1609, a 110.1 percent advantage for Intel. Any workload that lives on one fast thread, older applications, lightly threaded productivity software, snappy UI responsiveness, belongs to the i3-1315U without question.

The V2546's wins are narrower and clustered. It takes data compression at 136097 vs 126436 (7.1 percent), data encryption at 8046 vs 7583 (5.8 percent), and extended instructions at 8799 vs 7413 (15.8 percent). Compression and encryption are workloads where its 51.2 GB/s of memory bandwidth and dual-channel DDR4 with ECC support matter more than peak core speed, and the extended instructions result suggests it handles vectorized code paths efficiently. If the deployment is a long-running embedded system doing bulk data movement, hashing, or archival compression, the V2546 holds real advantages.

Architecture Differences

These are two very different designs converging on similar overall performance. The i3-1315U is Intel's Raptor Lake-U architecture on a 10 nm Intel process, launched January 3, 2023. It pairs 6 cores with 8 threads, a hybrid-style thread arrangement that shows up in its results: strong burst performance with a 4.50 GHz boost clock against a low 1.20 GHz base, and a 15 W TDP. Cache is generous per core, with 80 KB of L1 and 1.25 MB of L2 per core, plus 10 MB of shared L3.

The V2546 is AMD's Zen 2 (Renoir) design, built on TSMC's 7 nm node and released November 9, 2020. It runs 6 cores and 12 threads, the classic SMT arrangement, with a 3.00 GHz base and 3.95 GHz boost, all under a 35 W TDP. Its caches are smaller per core, 64 KB of L1 and 512 KB of L2, with 8 MB of shared L3, but the database records 9,800 million transistors on a 156 mm² die. The extra threads did not translate into multi-thread wins here; the i3-1315U's newer cores overcame the thread-count deficit in every Cinebench multi-core run.

Platform support diverges sharply. The V2546 supports DDR4 only, but with ECC, which the Intel part lacks, and with a recorded 51.2 GB/s bandwidth figure. It also offers 20 PCIe Gen 3 lanes, versus 8 PCIe Gen 4 lanes on the i3-1315U. That is a trade between lane count and lane speed: the AMD part can hang more devices off the CPU, the Intel part gives each lane twice the bandwidth. Memory flexibility favors Intel, which accepts both DDR4 and DDR5. Integrated graphics differ too, UHD Graphics 64EU on Intel versus Radeon Graphics 384SP on AMD, though the database records no GPU benchmarks. Neither chip has an unlocked multiplier.

The Verdict

For general-purpose mobile compute, the data is unambiguous: the i3-1315U is the stronger processor, winning 14 of 17 benchmarks with an average benchmark score of 15022 against 14336. It delivers roughly 14 percent more rendering performance at less than half the TDP (15 W vs 35 W), and doubles the V2546 in PassMark single-thread. Its nearest rivals in the database include the AMD EPYC 74F3 (avgScore 14915, within 0.7 percent) and the Intel Core i7-9750H (14886, within 0.9 percent), which places it in surprisingly capable company for its class.

Choose the V2546 when platform requirements, not raw speed, drive the decision: ECC memory for data integrity, 20 PCIe lanes for expansion, and the compression, encryption, and extended-instruction wins that come with them. Its own rival set, the Ryzen 5 3501U (14320 avgScore, 0.1 percent away) and the Intel Core i5-10400F (14185, 1.1 percent away), frames it as an embedded-focused part in mainstream company. For everything else, rendering, physics, integer and floating point math, and especially single-threaded responsiveness, the i3-1315U is the clear pick.

FAQ

Q: Which CPU is faster overall?

A: The Intel Core i3-1315U. It wins 14 of 17 head-to-head benchmarks, posts an average benchmark score of 15022 vs 14336, and leads every Cinebench test by roughly 14 percent.

Q: Does the AMD Ryzen Embedded V2546 win anything?

A: Yes, three PassMark tests: data compression (136097 vs 126436, 7.1 percent), data encryption (8046 vs 7583, 5.8 percent), and extended instructions (8799 vs 7413, 15.8 percent).

Q: Which has more threads?

A: The V2546, with 12 threads versus 8 on the i3-1315U. Both have 6 cores. The thread advantage did not produce multi-thread wins for AMD in the recorded data.

Q: How do their power envelopes compare?

A: The i3-1315U is a 15 W part; the V2546 runs at 35 W. The Intel chip delivers its benchmark wins at the lower power rating.

Q: How do they rank against all CPUs in the database?

A: Both sit at the 69th percentile, so despite the head-to-head gap, they occupy the same overall tier of performance.

Head-to-Head Benchmarks

Start with single-thread, the widest gap on record. The i3-1315U scores 3380 in PassMark single-thread against 1609 for the V2546, a 110.1 percent lead that alone explains most everyday responsiveness differences. Cinebench single-core results echo the same direction more moderately: 133 vs 116 in R15 (14.7 percent), 555 vs 486 in R20 (14.2 percent), and 1323 vs 1158 in R23 (14.2 percent).

Multi-core follows suit despite AMD's 12 threads versus Intel's 8. Cinebench R15 multi goes to Intel 944 to 827 (14.1 percent), R20 goes 3937 to 3446 (14.2 percent), and R23 goes 9374 to 8207 (14.2 percent). PassMark multithread lands at 11482 vs 9656, an 18.9 percent Intel win. The thread count could not offset the per-core deficit.

The synthetic math tests turn a consistent lead into a rout. Floating point math: 27012 vs 18534, Intel by 45.7 percent. Integer math: 37644 vs 30739, Intel by 22.5 percent. Physics: 706 vs 441, Intel by 60.1 percent. Prime number search: 41 vs 22, Intel by 86.4 percent. Random string sorting is the closest contest anywhere on the page, 14028 vs 13926, a 0.7 percent Intel edge that is effectively a tie.

Then the three AMD wins. Data compression goes to the V2546, 136097 vs 126436, a 7.1 percent margin. Data encryption follows, 8046 vs 7583, 5.8 percent. Extended instructions is AMD's best showing, 8799 vs 7413, a 15.8 percent win. All three favor the chip with the higher memory bandwidth and ECC-capable memory subsystem.
