AMD EPYC 7773X vs AMD Ryzen 5 7535HS Comparison

Head-to-Head Benchmarks

The benchmark data reveals a decisive split between these two AMD processors. The AMD EPYC 7773X dominates in multi-threaded and heavily parallel workloads, while the AMD Ryzen 5 7535HS secures a narrow win in single-core performance. The head-to-head comparison shows the EPYC 7773X winning 5 out of 6 tests, with the Ryzen 5 7535HS taking only 1.

The most dramatic difference appears in Cinebench R23 multi-core, where the EPYC 7773X scores 77,639 compared to the Ryzen 5 7535HS's 8,613. This represents an 88.9% deficit for the mobile chip, reflecting the sheer scale of core-count disparity. Similarly, in Cinebench R15 multi-core, the EPYC 7773X posts 7,825 against 1,457 for the Ryzen 5 7535HS, an 81.4% gap. These are not incremental differences; they are order-of-magnitude jumps that separate a 6-core mobile processor from a 64-core server part.

Single-core results tell a different story, though the EPYC 7773X still leads in most tests. In Cinebench R23 single-core, the EPYC 7773X scores 10,960 versus 1,445 for the Ryzen 5 7535HS, a 86.8% advantage. Cinebench R15 single-core shows a similar pattern: 1,104 for the EPYC 7773X against 232 for the Ryzen 5 7535HS, a 79% gap. These results may seem counterintuitive given the Ryzen 5 7535HS's higher boost clock of 4.55 GHz versus 3.50 GHz, but the EPYC 7773X's Zen 3 architecture at higher thermal headroom evidently compensates.

The one bright spot for the Ryzen 5 7535HS is Geekbench single-core, where it scores 1,654 against the EPYC 7773X's 1,536. That 7.7% margin is modest but real, suggesting the mobile chip's Zen 3+ architecture and higher clock speeds deliver tangible benefits in lightly-threaded, latency-sensitive workloads. However, in Geekbench multi-core, the EPYC 7773X reasserts dominance with 15,554 versus 7,354, a 52.7% lead.

The average benchmark scores place both processors at the same percentile (73rd) among all CPUs, with the Ryzen 5 7535HS averaging 19,047 and the EPYC 7773X averaging 18,979. Their nearest rivals include the Intel Core i5-12400F, Intel Core i5-1335U, and Intel Core 3 201E, all within a 0.4% delta. This parity in average score is remarkable given the architectural gulf between the two, but it reflects the fact that the Ryzen 5 7535HS's benchmark set includes lighter workloads like PassMark tests where it excels, while the EPYC 7773X's set is dominated by heavy Cinebench and Geekbench multi-threaded tests.

Architecture Differences

The architectural divide between these two processors is fundamental, starting with process node and core topology. The Ryzen 5 7535HS uses TSMC's 6 nm process with a 208 mm² die, while the EPYC 7773X uses TSMC's 7 nm process with 8x 81 mm² chiplets totaling 33,200 million transistors. The EPYC 7773X's chiplet design is a classic server approach, spreading 64 cores across multiple dies, whereas the Ryzen 5 7535HS integrates 6 cores on a single monolithic die.

Core and cache configurations diverge sharply. The Ryzen 5 7535HS offers 6 cores and 12 threads, while the EPYC 7773X provides 64 cores and 128 threads. Both share the same L1 and L2 cache structure at 64 KB and 512 KB per core respectively, but L3 cache differs massively: the Ryzen 5 7535HS has 16 MB shared, while the EPYC 7773X packs 768 MB shared. That 768 MB L3 is a defining feature for the server part, enabling large working sets to remain on-die.

Memory architecture reflects their respective markets. The Ryzen 5 7535HS supports DDR5 with dual-channel memory and 76.8 GB/s bandwidth, while the EPYC 7773X uses DDR4 with eight-channel memory and 204.8 GB/s bandwidth. The EPYC 7773X also supports ECC memory, which the Ryzen 5 7535HS does not. PCIe connectivity differs as well: the Ryzen 5 7535HS provides Gen 4 with 20 lanes, while the EPYC 7773X provides Gen 4 with 128 lanes.

Clock speeds favor the mobile chip nominally. The Ryzen 5 7535HS has a base clock of 3.30 GHz and boost clock of 4.55 GHz, versus 2.20 GHz base and 3.50 GHz boost for the EPYC 7773X. However, the EPYC 7773X's much higher thermal design power of 280 watts versus 35 watts allows it to sustain higher performance per core under load, which explains its single-core Cinebench victories. The Ryzen 5 7535HS includes integrated Radeon 660M graphics; the EPYC 7773X has none.

Sockets and packaging differ entirely: the Ryzen 5 7535HS uses AMD Socket FP7 (mobile), while the EPYC 7773X uses AMD Socket SP3 (server). The Ryzen 5 7535HS is from the 7000 series (Zen 3+ Rembrandt-R), while the EPYC 7773X is from the EPYC 7003 series (Zen 3 Milan-X). Both are currently in active production, with the Ryzen 5 7535HS released on 2023-01-03 and the EPYC 7773X on 2022-03-21.

Where Each One Wins

The EPYC 7773X is the clear choice for multi-threaded, throughput-intensive workloads. Its 64 cores and 128 threads provide massive parallel processing capability, which the benchmark data confirms. In Cinebench R23 multi-core, it achieves 77,639, a score that dwarfs the Ryzen 5 7535HS's 8,613. This makes it suitable for server virtualization, database processing, scientific computing, and any workload that can utilize dozens of threads simultaneously. The 768 MB L3 cache further enhances performance in data-heavy applications by reducing memory latency and increasing effective bandwidth.

The Ryzen 5 7535HS, by contrast, is optimized for mobile efficiency and lighter workloads. Its 35-watt TDP and integrated Radeon 660M graphics make it suitable for laptops where power consumption and heat dissipation are critical constraints. The Geekbench single-core win (1,654 versus 1,536) suggests it handles everyday tasks like web browsing, office applications, and single-threaded legacy software with slightly better responsiveness. Its DDR5 memory support and higher boost clock of 4.55 GHz contribute to snappy performance in latency-sensitive, lightly-threaded scenarios.

For mixed workloads, the data shows the EPYC 7773X still leads in most single-core tests, which is surprising given its lower clock speed. The Cinebench R23 single-core score of 10,960 versus 1,445 for the Ryzen 5 7535HS indicates that the EPYC 7773X's Zen 3 cores, despite running at 3.50 GHz boost, outperform the Zen 3+ cores at 4.55 GHz in this benchmark. This suggests that for professional single-threaded tasks like CAD or certain rendering operations, the EPYC 7773X may still be preferable, though the power and platform requirements are substantial.

The Ryzen 5 7535HS's PassMark results, while not directly compared head-to-head, show strengths in data compression (221,668), integer math (62,372), and floating-point math (35,540), indicating solid general-purpose performance for a mobile chip. The EPYC 7773X's absence from these tests means its PassMark performance is unknown, but its Cinebench and Geekbench results paint a picture of a processor that excels when fully utilized.
