AMD EPYC 7573X vs AMD Ryzen 5 4600G Comparison

The AMD Ryzen 5 4600G and the AMD EPYC 7573X occupy opposite ends of the processor spectrum. The Ryzen 5 4600G is a 6-core desktop APU designed for mainstream systems with integrated graphics. The EPYC 7573X is a 32-core server processor built for heavy multi-threaded workloads. The recorded data shows a complete sweep in favor of the EPYC part across all shared benchmark tests, but the magnitude of the differences varies depending on the workload.

Head-to-Head Benchmarks

The dataset includes six direct comparison points, all from the Cinebench suite. The EPYC 7573X wins every single test, with a consistent performance gap of 77 percent in its favor across all six metrics. This uniformity is notable. It means the EPYC does not just scale better under multi-thread loads; it also maintains a decisive advantage in single-thread performance.

Looking at the multi-core results, the EPYC 7573X scores 5948 points in Cinebench R15 multi-core, while the Ryzen 5 4600G scores 1370 points. In Cinebench R20 multi-core, the EPYC reaches 24787 points against the Ryzen’s 5709 points. The gap persists in Cinebench R23 multi-core, where the EPYC records 59017 points and the Ryzen 5 4600G scores 13593 points. In each case, the EPYC leads by the same 77 percent margin, indicating that its advantage scales linearly with the thread count difference.

Single-thread results tell a similar story. The EPYC 7573X scores 839 points in Cinebench R15 single-core, 3499 points in R20 single-core, and 8331 points in R23 single-core. The Ryzen 5 4600G trails with 193, 805, and 1919 points respectively. The 77 percent delta is consistent here as well. This is unexpected for a server part with a lower base clock. The EPYC runs at 2.80 GHz base and 3.60 GHz boost, while the Ryzen 5 4600G runs at 3.70 GHz base and 4.20 GHz boost. Despite the lower clock speeds, the EPYC’s Zen 3 architecture delivers significantly better single-thread throughput.

The database also records benchmark scores outside the head-to-head comparison. The Ryzen 5 4600G has a large set of additional tests. Its 3DMark results range from 726 points in single-thread to 4889 points in max threads. The Geekbench single-core score is 1460, and multi-core is 6637. PassMark tests show a single-thread score of 2653 and a multithread score of 15992. The EPYC 7573X only has Cinebench scores in the database, so no direct comparison is possible on those other workloads. However, the existing data clearly shows the EPYC’s dominance.

The average benchmark scores in the database place both processors in the same percentile relative to all CPUs, at 71st percentile each. The Ryzen 5 4600G has an average benchmark score of 17507, while the EPYC 7573X has an average of 17070. This is a curious data point. The EPYC wins every head-to-head test, yet its average score is slightly lower. This is explained by the fact that the average includes different sets of tests for each processor. The Ryzen’s average incorporates 3DMark and PassMark scores, which are not recorded for the EPYC. The EPYC’s average is based solely on its six Cinebench results, which are high but only cover a narrow set of workloads.

Where Each One Wins

The EPYC 7573X wins in every category where the two overlap. Its multi-thread performance is exceptional. With 32 cores and 64 threads, it is built for rendering, scientific computing, and database workloads. The Cinebench R23 multi-core score of 59017 is more than four times the Ryzen’s 13593. This makes the EPYC the clear choice for any application that can utilize many threads.

The EPYC also wins in single-thread performance, despite having lower clock speeds. Its Zen 3 architecture provides higher instructions per clock than the Zen 2 architecture in the Ryzen 5 4600G. The Cinebench R23 single-core score of 8331 versus 1919 shows a 77 percent lead. This means even lightly threaded applications, such as legacy software or certain scripting workloads, will run faster on the EPYC.

The Ryzen 5 4600G has one clear advantage: integrated graphics. It includes Radeon Vega 7 graphics, while the EPYC 7573X has no integrated graphics at all. This makes the Ryzen 5 4600G usable in a desktop system without a discrete GPU. It is suitable for office work, media consumption, and light gaming. The EPYC requires a separate graphics card for any display output, which is typical for server processors.

The Ryzen 5 4600G also has a much lower thermal design power at 65 watts, compared to the EPYC’s 280 watts. This makes the Ryzen far easier to cool and suitable for compact or low-power builds. The EPYC demands robust cooling solutions and a motherboard capable of delivering substantial power. The Ryzen’s unlocked multiplier also allows overclocking, while the EPYC’s multiplier is locked.

Architecture Differences

The two processors come from different generations of AMD’s Zen architecture. The Ryzen 5 4600G is built on Zen 2 with the Renoir codename. The EPYC 7573X is built on Zen 3 with the Milan-X codename. Both use a 7 nm process node fabricated by TSMC, but the transistor counts differ significantly. The Ryzen 5 4600G has 9,800 million transistors on a 156 mm² die. The EPYC 7573X uses a chiplet design with 8x 81 mm² dies and a total of 33,200 million transistors.

Cache layouts are fundamentally different. The Ryzen 5 4600G has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 8 MB of shared L3 cache. The EPYC 7573X also has 64 KB L1 and 512 KB L2 per core, but its L3 cache is 768 MB shared. This massive L3 cache is the defining feature of the Milan-X series. It provides a substantial advantage in workloads that benefit from large data sets residing in cache, such as in-memory databases and high-performance computing.

Memory support also differs. Both support DDR4 memory, but the Ryzen 5 4600G uses a dual-channel memory bus with a bandwidth of 51.2 GB/s. The EPYC 7573X uses an eight-channel memory bus with a bandwidth of 204.8 GB/s. The EPYC also supports ECC memory, which is critical for server reliability. The Ryzen 5 4600G does not support ECC. The EPYC provides 128 PCIe Gen 4 lanes from the CPU, while the Ryzen 5 4600G provides 20 PCIe Gen 3 lanes.

The socket and platform are entirely different. The Ryzen 5 4600G uses AMD Socket AM4, which is a mainstream desktop socket. The EPYC 7573X uses AMD Socket SP3, which is a server platform. The Ryzen 5 4600G has a base clock of 3.70 GHz and a boost clock of 4.20 GHz. The EPYC has a base clock of 2.80 GHz and a boost clock of 3.60 GHz. The Ryzen’s higher clocks are offset by the EPYC’s superior architecture and core count.
