Q: Which processor has integrated graphics?

A: The Ryzen 5 5600G includes Radeon Vega 7 integrated graphics. The EPYC 9454P has no integrated graphics, as it is designed for server and workstation applications.

Architecture Differences

The architectural gap between these two AMD parts is substantial. The Ryzen 5 5600G is based on the Zen 3 architecture, codenamed Cezanne, and is built on TSMC’s 7 nm process. It features 6 cores and 12 threads, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. The chip uses a monolithic design with a die size of 180 mm² and 10,700 million transistors. Its cache hierarchy consists of 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache.

In contrast, the EPYC 9454P belongs to the EPYC 9004 series and uses the Zen 4 architecture, codenamed Genoa. It is fabricated on TSMC’s 5 nm process and is a chiplet-based design: eight 72 mm² dies together contain 52,560 million transistors. The EPYC offers 48 cores and 96 threads, with a lower base clock of 2.75 GHz and a boost clock of 3.80 GHz. Its cache layout is markedly different: 64 KB of L1 per core, 1 MB of L2 per core, and a massive 256 MB of shared L3 cache.

The memory and I/O subsystems also diverge sharply. The Ryzen 5 5600G uses DDR4 memory on a dual-channel bus, yielding 51.2 GB/s of bandwidth, and it does not support ECC. The EPYC 9454P uses DDR5 on a twelve-channel bus, with 460.8 GB/s of bandwidth, and it supports ECC. PCIe connectivity differs as well: the Ryzen provides Gen 3 with 16 CPU lanes, while the EPYC provides Gen 5 with 128 CPU lanes. The Ryzen includes Radeon Vega 7 integrated graphics, which is absent on the EPYC. The Ryzen’s multiplier is unlocked, while the EPYC’s is locked. The EPYC is a server and workstation part, whereas the Ryzen is a desktop processor.

Where Each One Wins

The recorded benchmark data makes the division of labor clear: the EPYC 9454P wins every single head-to-head comparison in the database. However, the margin of victory varies widely depending on the workload, and that variance reveals where each chip can be considered viable.

The EPYC 9454P is the unequivocal winner in heavily threaded and multi-core scenarios. Its 48-core, 96-thread configuration crushes the Ryzen 5 5600G in Cinebench R23 multi-core, scoring 81,492 versus 10,551. It also leads Geekbench multi-core with 19,941 versus 8,428. For any server, scientific computing, or virtualization workload that scales across many threads, the EPYC is the only choice from this pairing.

The Ryzen 5 5600G, despite losing all head-to-head tests, retains a role in single-threaded and lightly threaded tasks where the EPYC’s advantage narrows. In Geekbench single-core, the EPYC leads by only 10.4% (2,011 versus 1,801). The Ryzen’s higher base and boost clocks (3.90 GHz and 4.40 GHz versus 2.75 GHz and 3.80 GHz) help it stay competitive in latency-sensitive, single-threaded desktop applications. Additionally, the Ryzen’s integrated Radeon Vega 7 graphics make it a complete package for a desktop system without a discrete GPU, something the EPYC cannot offer.

Head-to-Head Benchmarks

The database records six direct comparisons between the Ryzen 5 5600G and the EPYC 9454P, all of which the EPYC wins. The largest margin appears in Cinebench R23 multi-core, where the EPYC scores 81,492 against the Ryzen’s 10,551, a delta of -87.1%. This result is consistent with the core count disparity: 48 cores versus 6 cores.

Cinebench R15 multi-core follows a similar pattern, with the EPYC scoring 8,214 and the Ryzen scoring 1,724, a delta of -79%. Geekbench multi-core shows a smaller gap: the EPYC scores 19,941 versus 8,428, a delta of -57.7%. Even in single-core tests, the EPYC prevails, though the advantage is much narrower in Geekbench single-core: 2,011 versus 1,801, a delta of -10.4%. The Cinebench R23 single-core result is more lopsided, at 11,504 versus 1,409, a delta of -87.8%, and Cinebench R15 single-core shows 1,159 versus 228, a delta of -80.3%.

The data indicates that the EPYC’s Zen 4 architecture, higher core count, and massive L3 cache (256 MB versus 16 MB) provide overwhelming advantages in both multi-threaded and single-threaded Cinebench workloads. The Ryzen’s higher clocks help it close the gap in Geekbench single-core, but it still loses decisively.

The benchmark suite also shows a stark contrast in the breadth of tests recorded. The Ryzen 5 5600G has additional scores in 3DMark and Passmark tests, including 3DMark single-thread (872), 3DMark 16 threads (5,451), Passmark multi-thread (19,717), and Passmark single-thread (3,177). The EPYC 9454P has no recorded scores for those tests in this database, so direct comparisons for those workloads are not available.

The Verdict

The AMD EPYC 9454P is the clear performance winner in every head-to-head benchmark recorded. For any workload that can utilize more than 6 cores, the EPYC’s 48-core, 96-thread design delivers results that the Ryzen 5 5600G cannot approach: the EPYC is 87.1% faster in Cinebench R23 multi-core and 57.7% faster in Geekbench multi-core. The EPYC also leads in single-core tests, albeit by a smaller margin in Geekbench (10.4%).

The Ryzen 5 5600G, however, is not without purpose. Its higher base and boost clocks, combined with integrated Radeon Vega 7 graphics, make it a self-contained desktop processor for light to moderate workloads where a discrete GPU is not required. Its 65 W TDP is also far lower than the EPYC’s 290 W, making it suitable for compact or power-conscious desktop builds. The Ryzen’s unlocked multiplier adds flexibility for enthusiasts, while the EPYC’s locked multiplier reflects its server focus.

From the data, the selection is straightforward: the EPYC 9454P is for server, workstation, and heavily threaded environments where raw compute capacity is paramount. The Ryzen 5 5600G is for desktop users who prioritize a complete, low-power platform with integrated graphics and do not need massive multi-core throughput. The EPYC’s launch MSRP of $4598 and the Ryzen’s launch MSRP of $259 reflect their different market positions, but the benchmark results alone justify the EPYC’s dominance in performance metrics.
