AMD EPYC 8434PN

The AMD EPYC 8434PN is an EPYC 8004-series Server/Workstation processor using Zen 4c (Siena) and built for AMD Socket SP6. It supplies 48 cores and 96 threads, with a 2000.00 base clock, a 3.00 boost clock, 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of shared L3. Memory support is six-channel DDR5 with ECC and 230.4 GB/s bandwidth, while PCIe is Gen 5 with 96 CPU lanes. The TDP is 155, the launch MSRP is $3150, and the database places it at the 50th percentile among all CPUs, with an empty benchmark array.

Single-Thread vs Multi-Thread Behavior

The EPYC 8434PN is a 48-core, 96-thread processor with a 2000.00 base clock and a 3.00 boost clock. That clock profile is not aimed at raw single-thread speed; instead, the processor’s throughput comes from core count and shared cache. Each core has 64 KB of L1 and 1 MB of L2, so even in single-threaded bursts the active core has a local cache hierarchy to work with. The 3.00 boost clock is the ceiling for lightly threaded work. When only a few threads are active, that ceiling is the limiting factor; the remaining cores cannot contribute.

In multi-threaded work, the picture changes. All 48 cores can operate at the 2000.00 base clock as a sustained floor, and the 96 threads create a large execution resource for the operating system. The 128 MB shared L3 is a major asset for parallel workloads because it lets many cores share data without going to system memory. The six-channel DDR5 interface with 230.4 GB/s bandwidth feeds those cores. Workloads that scale across many parallel threads are the natural fit. Workloads dominated by a single thread will spend most of the processor’s capacity idle.

The result is a clear behavioral split. For high-core-count throughput, the EPYC 8434PN has the right resources: 48 cores, 96 threads, 128 MB of shared L3, and high memory bandwidth. For single-thread responsiveness, it is a moderate-clocked server part.

Power and Thermals

The listed TDP is 155. That is the number a cooling solution must be designed around. The processor is built on TSMC’s 5 nm process, with 35,500 million transistors in a 4x 73 mm² multi-die package. The 5 nm node is the listed manufacturing process, and the TDP is 155. Since this is a Socket SP6 part, the cooling solution must physically match SP6 and be capable of handling a 155 TDP under sustained server load.

The multiplierUnlocked field is false, so there is no overclocking power overhead to reserve. The market segment is Server/Workstation, which implies server-class cooling rather than desktop-style overclocking hardware. Production status is Active. A 155 TDP part in a server socket is a mid-pack thermal load; it does not require exotic cooling, but it does require a properly specified SP6 heatsink.

How It Compares

The nearestRivals list is empty. There are no rival names, no rival scores, and no comparative percentages available for this section. With no nearest-rival list, the only positional metric is the 50th percentile among all CPUs. That places the EPYC 8434PN at the median of the database’s all-CPU distribution. It cannot be said to lead or trail any specific rival by a percentage from the supplied data.

The specifications make the intended market position clear: a 48-core, 96-thread Socket SP6 EPYC part in the 8004 series. Until the comparison tables are populated, head-to-head positioning against named processors is not possible.

Benchmark Performance

The benchmark array is empty, and the avgBenchmarkScore field is 0. No score data is available for this processor, so the database does not provide a measured single-thread or multi-thread performance average. The percentileVsAllCpus field is 50, which is a broad positional signal rather than a score. Since nearestRivals is also empty, there are no exact percentage deltas to report against competing CPUs.

What can be analyzed is the specification-level performance picture. The part combines 48 cores and 96 threads with a 2000.00 base clock and a 3.00 boost clock. The base clock defines an all-core floor, while the boost clock defines the ceiling for lighter loads. The 128 MB shared L3 and 230.4 GB/s six-channel memory bandwidth are the resources that support thread-scaled workloads. A 50th percentile all-CPU placement is consistent with a processor that is neither at the top of the database nor at the bottom, but exact score deltas are absent. Without scores, the practical ranking against named rivals cannot be determined from the supplied data.

Platform and Compatibility

The EPYC 8434PN uses AMD Socket SP6 and belongs to the EPYC 8004 series, with the Siena codename and Zen 4c architecture. The platform supports DDR5 memory through a six-channel memory bus, with ECC memory enabled and 230.4 GB/s bandwidth. PCIe is Gen 5 and provides 96 lanes (CPU only). The CPU is built on TSMC’s 5 nm process with 35,500 million transistors in a 4x 73 mm² package. The market segment is Server/Workstation. Production status is Active. The part number is 100-000001174. The integrated-graphics field is null, meaning no integrated graphics is listed. The multiplier is not unlocked.

For an upgrade path, the socket is the main constraint: any board or cooling solution must be Socket SP6-compatible to use this EPYC 8004-series processor.
