AMD EPYC 4005 Processors
AMD EPYC 4005 processors offer up to 16 Zen 5 cores, DDR5-5600 and PCIe 5.0 for hosting, web servers and growing businesses.
AMD EPYC 4005 CPUs for businesses and hosting
AMD EPYC 4005 processors bring the powerful Zen 5 architecture to compact and cost-efficient single-socket servers. With six to 16 cores, high clock speeds and PCIe 5.0, the CPUs are suitable for dedicated hosting, web servers, business applications, development environments, databases and smaller virtualisation platforms.
Which AMD EPYC 4005 CPU is right for me?
The models in the AMD EPYC 4005 series differ in core count, clock speed, cache and power consumption. The following overview will help you choose the right server processor for your application.
| Application | Recommended AMD EPYC 4005 CPUs |
|---|---|
| Dedicated hosting & VPS | EPYC 4585PX, EPYC 4565P, EPYC 4545P, EPYC 4465P |
| Web, mail & application servers | EPYC 4545P, EPYC 4465P, EPYC 4345P, EPYC 4245 |
| Software development & build servers | EPYC 4565P, EPYC 4545P, EPYC 4465P |
| Databases & e-commerce | EPYC 4585PX, EPYC 4565P, EPYC 4545P, EPYC 4345P |
| Game servers & latency-sensitive hosting | EPYC 4585PX, EPYC 4565P, EPYC 4345P |
| File, backup & infrastructure systems | EPYC 4465P, EPYC 4345P, EPYC 4245 |
| AI-assisted services & video analytics | EPYC 4585PX, EPYC 4565P, EPYC 4545P |
Models with twelve or 16 cores are suitable for many parallel processes, virtual instances and extensive build projects. Web servers, business applications and smaller infrastructure services, on the other hand, can already operate efficiently with six or eight cores.
What the EPYC 4005 model suffixes mean
P suffix
AMD EPYC 4005 processors with the P suffix are designed for single-socket servers. Only one CPU can therefore be installed per motherboard. The EPYC 4245 without a P suffix is also intended exclusively for systems with one processor socket within this series.
PX suffix
The AMD EPYC 4585PX combines the single-socket design with AMD 3D V-Cache. With 128 MB of L3 cache, the CPU is particularly suitable for cache-intensive databases, game servers, development environments and other applications that frequently access recurring data.

| AMD EPYC 4585PX | 16 / 32 | Zen 5 with 3D V-Cache | not yet specified | 128 MB | 170 W |
| AMD EPYC 4565P | 16 / 32 | Zen 5 | 4.30 / 5.70 GHz | 64 MB | 170 W |
| AMD EPYC 4545P | 16 / 32 | Zen 5 | 3.00 / 5.40 GHz | 64 MB | 65 W |
| AMD EPYC 4465P | 12 / 24 | Zen 5 | 3.40 / 5.40 GHz | 64 MB | 65 W |
| AMD EPYC 4345P | 8 / 16 | Zen 5 | 3.80 / 5.30 GHz | 32 MB | 65 W |
| AMD EPYC 4245 | 6 / 12 | Zen 5 | 3.90 / 5.10 GHz | 32 MB | 65 W |
AMD EPYC 4005 or EPYC 4004?
The AMD EPYC 4005 series is based on the newer Zen 5 architecture and supports DDR5 memory at speeds of up to 5,600 MT/s. It offers six to 16 cores and is particularly suitable for modern hosting, development, database and business servers.
AMD EPYC 4004 processors use Zen 4 and support DDR5 at speeds of up to 5,200 MT/s. The older series offers a wider selection of models, starting with four cores. The more suitable generation depends on motherboard support, budget and the required processing performance.
AMD EPYC 4005 processor compatibility
Socket
AMD EPYC 4005 processors use Socket AM5 and are intended exclusively for single-socket systems. Despite using a familiar socket, the CPU should only be installed in a motherboard that explicitly supports EPYC 4005.
Memory
The processors support two DDR5 memory channels at speeds of up to 5,600 MT/s. Compatible DDR5 ECC UDIMMs are required for professional servers. DDR5 RDIMMs for SP5 or SP6 platforms are not compatible.
Motherboard
An AM5 server motherboard with remote management or BMC is recommended for EPYC 4005. Check the CPU compatibility list, motherboard revision and required BIOS version before purchase.
Cooler
A compatible AM5 CPU cooler is required. It must be suitable for the TDP of the selected processor and the available height inside the server case. The EPYC 4005 models are rated for either 65 or 170 watts.

FAQ – AMD EPYC 4005 processors
Who are AMD EPYC 4005 processors suitable for?
The CPUs are designed for small and medium-sized businesses, hosting providers and system integrators. Typical applications include web, file, mail and application servers, development environments, databases and dedicated hosting systems.
What is the difference between EPYC 4004 and EPYC 4005?
EPYC 4005 is based on Zen 5 and supports DDR5 at speeds of up to 5,600 MT/s. EPYC 4004 uses Zen 4 and reaches speeds of up to DDR5-5200. Both series use Socket AM5 and are designed for single-socket servers.
Which socket do AMD EPYC 4005 CPUs use?
AMD EPYC 4005 processors use Socket AM5. However, the motherboard must explicitly support the selected CPU, as not every AM5 desktop motherboard is approved for EPYC server processors.
What do P and PX mean on EPYC 4005 processors?
P models are designed for single-socket servers. The PX suffix additionally indicates AMD 3D V-Cache. As a result, the EPYC 4585PX provides 128 MB of L3 cache for cache-intensive applications.
How many cores do AMD EPYC 4005 processors offer?
Depending on the model, the processors offer six to 16 Zen 5 cores and twelve to 32 threads. The standard models reach boost clock speeds of up to 5.7 GHz.
Which memory is required for EPYC 4005?
The platform supports DDR5 memory through two memory channels at speeds of up to 5,600 MT/s. Compatible DDR5 ECC UDIMMs should be used for professional servers.
How many PCIe lanes do AMD EPYC 4005 CPUs support?
All models support up to 28 PCIe 5.0 lanes. Depending on the motherboard, these can be used for NVMe SSDs, network cards, RAID controllers and graphics cards.
Are AMD EPYC 4005 processors suitable for game servers?
Yes. The high clock speeds are suitable for dedicated game servers. Thanks to its large L3 cache, the EPYC 4585PX may offer particular advantages in latency- and cache-sensitive applications.
