AMD EPYC 9454P

The AMD EPYC 9454P is a 48-core, 96-thread server/workstation processor from the EPYC 9004 series, built on Zen 4 (Genoa) at TSMC’s 5 nm process. It has a base clock of 2.75 GHz, a boost clock of 3.80 GHz, a 290 W TDP, and is packaged for AMD Socket SP5. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 256 MB of shared L3. The memory system is DDR5 on a twelve-channel bus with ECC, rated at 460.8 GB/s. The CPU exposes 128 PCIe Gen 5 lanes (CPU only), lists no integrated graphics, and carries an average benchmark score of 20422, which places it at the 78th percentile among all CPUs.

Benchmark Performance

Listed Cinebench results show strong multi-core output: R15 multi-core is 8214, R20 multi-core is 34226, and R23 multi-core is 81492. Geekbench multi-core is 19941. Single-core runs are 1159 in R15, 4831 in R20, 11504 in R23, and 2011 in Geekbench. Together, these numbers produce an average benchmark score of 20422 and a percentile rank of 78.

The average, however, is not a large lead over the nearest rivals. The AMD Ryzen 5 8500G scores 20425 with a deltaPct of 0. The AMD EPYC 7713 scores 20363 with a deltaPct of 0.3. The Intel Core Ultra 5 228V scores 20492 with a deltaPct of -0.3. The AMD Ryzen 7 4800H scores 20496 with a deltaPct of -0.4. In aggregate, the 9454P is tied with one rival, narrowly ahead of another, and narrowly behind two others. The R23 multi-core score of 81492 is the largest listed multi-thread result in the benchmark set, indicating that the aggregate average does not fully express the chip’s multi-thread capability. The single-core scores are present but not the defining feature; the data points to a processor designed for parallel workloads.

Power and Thermals

With a TDP of 290 W, this part sits in a power class that requires server-grade thermal management. It is manufactured on a 5 nm process by TSMC, with a transistor count of 52,560 million and a die layout listed as 8x 72 mm². These physical details make the power envelope understandable: a large number of transistors must be cooled while 48 cores and 96 threads operate across the package. The memory controller adds to the thermal load because it drives twelve-channel DDR5 memory at 460.8 GB/s. The PCIe Gen 5 interface also contributes, with 128 lanes (CPU only) available for data movement.

No integrated graphics is present, so the thermal solution does not cover a graphics die, but the CPU itself still requires high-capacity cooling. The data includes only a TDP specification rather than measured thermal results. That 290 W figure is the key thermal constraint for system design, and the server/workstation market segment reinforces the need for a cooling approach built around continuous multi-threaded operation.

How It Compares

The AMD Ryzen 5 8500G is a statistical tie in the aggregate metric. The 8500G averages 20425, while the 9454P averages 20422, and the deltaPct is exactly 0. Despite the EPYC’s far larger core count, the average benchmark score does not separate them. This is a useful reminder that an aggregate score can compress a very wide workload range into a single number.

The AMD EPYC 7713 is slightly behind the 9454P. The 7713 averages 20363, the 9454P averages 20422, and the deltaPct is 0.3. This is a narrow edge for the 9454P, but it is still only a fraction of a percentage point in the average. The result does not suggest a generational leap in aggregate terms, even though the 9454P is listed in the EPYC 9004 series.

The Intel Core Ultra 5 228V leads the 9454P by a small margin. The 228V averages 20492, the 9454P averages 20422, and the deltaPct is -0.3. This is a negative delta, meaning the EPYC’s average score is slightly lower than the rival’s. The difference is small enough that workload type would likely matter more than the aggregate ranking.

The AMD Ryzen 7 4800H has the largest negative delta among the listed nearest rivals. The 4800H averages 20496, the 9454P averages 20422, and the deltaPct is -0.4. Once again, this is a very small gap in the aggregate benchmark metric. All deltas remain fractions of a percentage point, so the 9454P’s average position is tightly packed with its nearest neighbors.

Platform and Compatibility

The AMD EPYC 9454P uses AMD Socket SP5 and belongs to the EPYC 9004 series. Its architecture is Zen 4, with the codename Genoa, and it is manufactured on the 5 nm process from TSMC. The CPU supports DDR5 memory with a twelve-channel bus, 460.8 GB/s bandwidth, and ECC memory. It provides 128 PCIe Gen 5 lanes (CPU only).

The package has no integrated graphics and no unlocked multiplier. The part number is 100-100000873. Production status is active, and the release date is listed as 2022-11-09. The launch MSRP is $4598.

For an upgrade path, the active production status and SP5 socket mean the platform can remain within the EPYC 9004 series family. The data does not list compatibility with older socket generations. The twelve-channel memory bus, ECC support, and 128 PCIe Gen 5 lanes all point to a server/workstation platform rather than a general desktop system.

Who Should Consider It

The benchmark evidence supports multi-threaded server and workstation workloads. Cinebench R23 multi-core 81492, R20 multi-core 34226, and R15 multi-core 8214 all show strong parallel performance. Tasks that keep 48 cores and 96 threads busy should follow that curve, including rendering, scientific computation, and other heavily parallel creation workloads.

The single-core results are not weak: Geekbench single-core is 2011, and Cinebench R23 single-core is 11504. An office workload could run on this hardware, but the 290 W TDP and server/workstation market segment make it an unusual choice for ordinary office deployments. The lack of integrated graphics also means a discrete GPU or other display solution is required for any graphical output.

For gaming, no gaming-specific benchmark is listed, so the data cannot validate gaming performance. What the data does show is a processor built around throughput, ECC memory support, and a large PCIe lane count. The primary audience is therefore the server and workstation segment, not the general desktop buyer.

Single-Thread vs Multi-Thread Behavior

Single-thread results are R15 1159, R20 4831, R23 11504, and Geekbench 2011. Multi-thread results are R15 8214, R20 34226, R23 81492, and Geekbench 19941. The pattern is consistent: multi-core scores are far higher than single-core scores across the board. For a 48-core, 96-thread processor, this is the expected shape.

The base clock of 2.75 GHz and boost clock of 3.80 GHz indicate that a lightly threaded workload can use a higher clock on individual cores, while all-core workloads rely on the full thread count. The 256 MB of shared L3 cache and 460.8 GB/s memory bandwidth support the parallel side of the chip by giving many cores shared data access and large memory throughput.

In real workloads, this split matters. Low-thread latency-sensitive tasks will depend on the 3.80 GHz boost behavior and the per-core single-thread scores. High-thread throughput tasks will depend on how well software can use 48 cores and 96 threads. The benchmark data clearly shows the chip is weighted toward the latter.
