AMD EPYC 7543P vs AMD Ryzen 3 7335U Comparison

The AMD Ryzen 3 7335U and the AMD EPYC 7543P sit at opposite ends of AMD's product stack, and the recorded data makes the split unmistakable. One is a 28 W mobile chip built for thin laptops, the other a 225 W server processor designed to fill a Socket SP3 board. Comparing them head-to-head is not a fight the Ryzen 3 can win, but the data still tells a useful story: the EPYC 7543P swept all six head-to-head benchmarks, while the 7335U holds its own when the database normalizes across its own market segment, landing in the 70th percentile of all CPUs, identical to the EPYC's percentile placement.

Where Each One Wins

The EPYC 7543P wins everywhere raw throughput is measured. It took all six Cinebench contests in the database, single-core and multi-core alike, by a margin of roughly 81 percent in every test. With 32 cores and 64 threads against the Ryzen's 4 cores and 8 threads, that multi-core outcome is expected, but the single-core sweep is the more interesting result: the EPYC's 3.70 GHz boost trails the Ryzen's 4.30 GHz, yet it still posts 8002 in Cinebench R23 single-core versus 1511 for the 7335U. Server-class infrastructure clearly feeds those cores better than a thin-and-light power envelope can.

The Ryzen 3 7335U's wins are structural rather than numeric. It draws 28 W against the EPYC's 225 W, it integrates Radeon 660M graphics where the EPYC has none, and it runs DDR5 in a dual-channel configuration while the EPYC uses DDR4 across eight channels. None of that shows up in a Cinebench chart, but it defines where each chip belongs: the 7335U in a self-contained mobile platform, the 7543P in a workstation or server with discrete graphics and substantial cooling.

FAQ

Q: Is the EPYC 7543P faster than the Ryzen 3 7335U?

A: Yes, in every recorded benchmark. The EPYC won all six head-to-head Cinebench tests, including single-core, with a delta of roughly 81 percent each time. Its Cinebench R23 multi-core score of 56683 is more than five times the Ryzen's 10703.

Q: Does the Ryzen 3 7335U have a higher boost clock?

A: Yes. It boosts to 4.30 GHz against the EPYC's 3.70 GHz. Despite the clock advantage, the recorded single-core scores still favor the EPYC, so clock speed alone does not determine the outcome here.

Q: Which chip has integrated graphics?

A: Only the Ryzen 3 7335U, with its Radeon 660M. The EPYC 7543P has no integrated graphics and requires a discrete GPU.

Q: What memory does each support?

A: The 7335U supports DDR5 on a dual-channel bus with 76.8 GB/s of bandwidth. The 7543P supports DDR4 on an eight-channel bus with 204.8 GB/s of bandwidth. Both support ECC memory.

Q: How do they compare against their own nearest rivals?

A: The 7335U's average benchmark score of 16827 sits within a fraction of a percent of the Intel Core i3-12100E (16853, delta -0.2 percent), Intel Core i5-1235U (16770, delta 0.3 percent), Intel Core Ultra 5 115U (16753, delta 0.4 percent), and AMD Ryzen 5 7235HS (16902, delta -0.4 percent). The EPYC's average of 16395 is similarly close to the AMD Ryzen 5 4600H (16341, delta 0.3 percent), Intel Core i7-1260U (16320, delta 0.5 percent), Intel Core i5-10600KF (16228, delta 1 percent), and Intel Core i7-10850H (16204, delta 1.2 percent).

Q: Do both support PCIe Gen 4?

A: Yes, but at very different scale. The 7335U exposes 20 CPU lanes, while the 7543P exposes 128 CPU lanes.

Head-to-Head Benchmarks

Every contest in the database went the same way, so the numbers are best read as a measure of scale rather than a back-and-forth battle.

In Cinebench R23 multi-core, the EPYC 7543P scored 56683 to the Ryzen 3 7335U's 10703. That is the practical difference between a chip that can sustain heavily threaded rendering or virtualization workloads and one that completes them eventually. Cinebench R20 multi-core shows the same shape: 23806 versus 4495. Cinebench R15 multi-core lands at 5713 versus 1078.

Single-core results repeat the pattern, which is the more surprising half of the data. Cinebench R23 single-core: 8002 for the EPYC, 1511 for the Ryzen. R20 single-core: 3360 versus 634. R15 single-core: 806 versus 152. Each of these is a delta of roughly 81 percent in the EPYC's favor, matching the multi-core margins almost exactly. In other words, the gap is not primarily about thread count, it is present even when both chips run one thread at a time, pointing to platform, power, and cache advantages on the server side rather than parallelism alone.

The 7335U does hold a 30-win advantage in one sense: it is the only chip here with Passmark subscores recorded, including 146309 in data compression, 9335 in data encryption, 24298 in floating point math, and 3053 in single-thread performance. Those figures place it competitively against its mobile rivals listed above, all within about half a percent on aggregate score.

Specification Differences

The two processors differ on nearly every line of the spec sheet:

• Cores/threads: 4 cores, 8 threads (7335U) versus 32 cores, 64 threads (7543P)
• Clocks: 3.00 GHz base, 4.30 GHz boost versus 2.80 GHz base, 3.70 GHz boost
• TDP: 28 W versus 225 W
• Socket: FP7 versus SP3
• L3 cache: 8 MB shared versus 256 MB shared
• Memory: DDR5 dual-channel at 76.8 GB/s versus DDR4 eight-channel at 204.8 GB/s
• PCIe: Gen 4 with 20 CPU lanes versus Gen 4 with 128 CPU lanes
• Graphics: Radeon 660M integrated versus none
• Segment: Mobile versus Server/Workstation
• Release: the 7335U arrived later, on 2023-01-03; the 7543P on 2021-03-14
• Launch MSRP: the EPYC 7543P carried a launch MSRP of $2730; no launch MSRP is recorded for the 7335U
• Die size: 208 mm² versus 8x 81 mm² chiplets, with 33,200 million transistors on the EPYC

Where they match: both are AMD parts, both support ECC, both use a 64 KB per-core L1 and 512 KB per-core L2, both are multiplier-locked, both remain in active production, and both sit in the 70th percentile versus all CPUs in the database.

Architecture Differences

The EPYC 7543P is a Zen 3 design, codenamed Milan, fabricated on TSMC's 7 nm process. The Ryzen 3 7335U is Zen 3+, codenamed Rembrandt-R, on a 6 nm process, making it the newer architecture generation of the pair. The practical consequence is modest for performance but real for efficiency: the 7335U extracts competitive per-core behavior from a much tighter power envelope.

The bigger architectural story is cache and topology. The EPYC's 256 MB of shared L3 dwarfs the Ryzen's 8 MB, and that cache feeds 32 cores across a chiplet layout (8x 81 mm² dies) rather than a single monolithic die. Combined with an eight-channel DDR4 memory subsystem delivering 204.8 GB/s, the EPYC is built to keep many cores busy simultaneously. The 7335U's dual-channel DDR5 at 76.8 GB/s is generous for a mobile part and unnecessary bandwidth for four cores to saturate lightly threaded work.

Expansion differs by an order of magnitude: 128 PCIe Gen 4 CPU lanes on the EPYC support dense storage and accelerator configurations; 20 lanes on the Ryzen suit a laptop's direct-attached SSD and discrete GPU needs. The 7335U's integrated Radeon 660M is the one feature the EPYC entirely lacks, reinforcing its self-sufficient mobile design.

The Verdict

The data supports exactly one conclusion for throughput buyers: the EPYC 7543P. It won all six head-to-head benchmarks by roughly 81 percent, and its infrastructure (256 MB L3, 204.8 GB/s memory bandwidth, 128 PCIe lanes) exists to convert its 32 cores into sustained work. Anyone running rendering, virtualization, or heavily threaded batch work on a Socket SP3 platform gets a chip in the 70th percentile of all CPUs in the database.

The Ryzen 3 7335U earns its place through a different logic. It matches the EPYC's 70th percentile placement despite drawing 28 W instead of 225 W, and its aggregate score of 16827 sits essentially even with chips like the Core i3-12100E and Ryzen 5 7235HS. For a mobile platform needing integrated Radeon 660M graphics, DDR5 support, and per-thread responsiveness from a 4.30 GHz boost clock, it is the only viable option of the two, since the EPYC has no graphics and no laptop-compatible socket. Pick the 7543P for a server; pick the 7335U for a thin-and-light. The benchmark tables leave no room for overlap between those use cases.
