AMD EPYC 9534 vs AMD Ryzen 5 7535U Comparison

The AMD Ryzen 5 7535U and the AMD EPYC 9534 occupy opposite ends of the processor spectrum. The Ryzen 5 7535U is a 6-core mobile chip from the 7000 series, while the EPYC 9534 is a 64-core server processor from the 9004 series. The head-to-head data shows a complete sweep for the EPYC in the four shared Cinebench tests, but the average benchmark scores and feature sets tell a more nuanced story for different use cases.

Head-to-Head Benchmarks

The database records four direct comparisons between these two processors, and the EPYC 9534 wins all of them. In Cinebench R15 multi-core, the EPYC scores 7632 against the Ryzen's 1330. That is an 82.6% deficit for the Ryzen. The single-core R15 test shows 1077 versus 225, a 79.1% gap. Moving to Cinebench R23, the multi-core result is 75715 for the EPYC and 8591 for the Ryzen. The Ryzen trails by 88.7%. The single-core R23 test has the EPYC at 10689 and the Ryzen at 1414, a 86.8% difference.

These are not close contests. The EPYC wins all four head-to-head tests, and the smallest margin is the 79.1% gap in R15 single-core, which is still a dominant victory. Interestingly, the Ryzen has a higher boost clock at 4.55 GHz versus the EPYC's 3.70 GHz, yet it still loses single-core tests. The data indicates the EPYC's Zen 4 architecture and much larger cache, 256 MB shared L3 versus 16 MB, provide a significant per-thread advantage in these workloads. The multi-core results are even more lopsided, with the EPYC's 64 cores and 128 threads overwhelming the Ryzen's 6 cores and 12 threads.

Where Each One Wins

The EPYC 9534 wins every head-to-head benchmark in the database. It is the clear winner in raw compute throughput, particularly in multi-threaded server tasks. However, the Ryzen 5 7535U wins in the overall average benchmark score. The Ryzen averages 22791 across all its recorded tests, while the EPYC averages 21900. The Ryzen also holds a higher percentile ranking at 76, compared to the EPYC's 75.

The Ryzen's average score of 22791 places it 0.7% ahead of the Intel Core i5-12500H (22625) and 0.8% ahead of the Intel Core Ultra 5 135U (22618). It is 0.1% behind the AMD Ryzen 5 2600X (22823) and 0.5% behind the AMD Ryzen 5 6600U (22897). The EPYC's average score of 21900 is exactly level with the AMD EPYC 9554P (21899) and the Intel Core i7-11700 (21891). It is 0.1% ahead of the AMD Ryzen 5 PRO 6650U (21874) and 0.2% behind the Intel Core Ultra 5 236V (21952).

So, the EPYC wins the specific Cinebench tests, but the Ryzen wins the broader average score metric. The Ryzen also has integrated graphics in the form of a Radeon 660M, which the EPYC lacks entirely. The Ryzen's lower TDP of 28 watts makes it suitable for mobile systems, while the EPYC's 280 watt TDP is designed for server racks.

Architecture Differences

The Ryzen 5 7535U uses the Zen 3+ architecture, codenamed Rembrandt-R, on a 6 nm TSMC process. The EPYC 9534 uses the Zen 4 architecture, codenamed Genoa, on a 5 nm TSMC process. Core counts differ massively: 6 cores and 12 threads for the Ryzen, versus 64 cores and 128 threads for the EPYC.

Cache hierarchies diverge as well. Both have 64 KB of L1 per core. The Ryzen has 512 KB of L2 per core and 16 MB of shared L3. The EPYC has 1 MB of L2 per core and 256 MB of shared L3. Memory support is DDR5 for both, but the bus widths differ. The Ryzen uses a dual-channel interface with 76.8 GB/s of bandwidth. The EPYC uses a twelve-channel interface with 460.8 GB/s of bandwidth.

PCIe connectivity is also different. The Ryzen offers Gen 4 with 20 lanes (CPU only). The EPYC offers Gen 5 with 128 lanes (CPU only). The physical packages are distinct. The Ryzen uses AMD Socket FP7 and has a die size of 208 mm². The EPYC uses AMD Socket SP5 and consists of 8 dies at 72 mm² each. The EPYC packs 52,560 million transistors, while the Ryzen's transistor count is not recorded in the database.

The Ryzen targets the mobile segment, while the EPYC targets the server and workstation segment. The Ryzen was released on 2023-01-03, and the EPYC on 2022-11-09. The Ryzen includes a Radeon 660M integrated GPU, while the EPYC has no integrated graphics. Both processors have locked multipliers and support ECC memory.
