With AMD you can pick between a similar 8-core SKU for closer to half the cost, or get twice as many cores for less either in higher or lower TDP. The only SKU that costs more than Intel\u2019s entry Xeon flagships is the AMD EPYC 4585PX, the part with 3D V-Cache which is a different chip.<\/p>\n<p>Something one of our team members mentioned, is that if you have applications that thrive on high cache per core, the AMD EPYC 4585PX is the Zen 5 option for higher cache per core in this generation as we do not have a Turin-X follow-up to Genoa-X in the EPYC 9000 line.<\/p>\n<p>Let us next get to the chips.<\/p>\n<h2>A Look at the AMD EPYC 4005<\/h2>\n<p>The AMD EPYC 4005 series is going to look a lot like two other AMD product families. It is essentially a Zen 5 update to the Zen 4-based EPYC 4004 series in the AM5 socket, so those are going to look a lot alike. Also, these platforms will look quite a bit like the AMD Ryzen 9000 series since those are the sister Zen 5 parts.<\/p>\n<figure id=\"attachment_86281\" aria-describedby=\"caption-attachment-86281\" style=\"width: 696px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.servethehome.com\/amd-epyc-4005-grado-is-great-and-intel-is-exposed\/amd-epyc-4005-grado-overview-with-epyc-4004-differences\/\" rel=\"attachment wp-att-86281\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-86281\" src=\"https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-4005-Grado-Overview-with-EPYC-4004-Differences-800x434.jpg\" alt=\"AMD EPYC 4005 Grado Overview With EPYC 4004 Differences\" width=\"696\" height=\"378\" srcset=\"https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-4005-Grado-Overview-with-EPYC-4004-Differences-800x434.jpg 800w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-4005-Grado-Overview-with-EPYC-4004-Differences-400x217.jpg 400w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-4005-Grado-Overview-with-EPYC-4004-Differences-774x420.jpg 774w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-4005-Grado-Overview-with-EPYC-4004-Differences-696x378.jpg 696w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-4005-Grado-Overview-with-EPYC-4004-Differences-1068x580.jpg 1068w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-4005-Grado-Overview-with-EPYC-4004-Differences.jpg 1268w\" sizes=\"auto, (max-width: 696px) 100vw, 696px\"\/><\/a><figcaption id=\"caption-attachment-86281\" class=\"wp-caption-text\">AMD EPYC 4005 Grado Overview With EPYC 4004 Differences<\/figcaption><\/figure>\n<p>The major changes in this generation are the update to the Zen 5 architecture with the full 512b AVX-512 data path.

The latter is interesting since this offers double the core count of the Xeon competition in this segment. Still, the answer if you want more is really that you go to a higher-end SKU. The AMD EPYC 7000, 8000, and 9000 series all offer more memory, more PCIe lanes, and more cores, while also having single-socket options. As much as I love having more memory and more PCIe lanes, AMD EPYC is now supporting four different sockets with increasing capabilities.<\/p>\n<figure id=\"attachment_86277\" aria-describedby=\"caption-attachment-86277\" style=\"width: 696px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.servethehome.com\/amd-epyc-4005-grado-is-great-and-intel-is-exposed\/amd-epyc-family-2025-05\/\" rel=\"attachment wp-att-86277\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-86277\" src=\"https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-Family-2025-05-800x437.jpg\" alt=\"AMD EPYC Family 2025 05\" width=\"696\" height=\"380\" srcset=\"https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-Family-2025-05-800x437.jpg 800w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-Family-2025-05-400x218.jpg 400w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-Family-2025-05-770x420.jpg 770w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-Family-2025-05-696x380.jpg 696w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-Family-2025-05-1068x583.jpg 1068w, https:\/\/www.servethehome.com\/wp-content\/uploads\/2025\/05\/AMD-EPYC-Family-2025-05.jpg 1257w\" sizes=\"auto, (max-width: 696px) 100vw, 696px\"\/><\/a><figcaption id=\"caption-attachment-86277\" class=\"wp-caption-text\">AMD EPYC Family 2025 05<\/figcaption><\/figure>\n<p>Another difference between the EPYC series, and the Ryzen series, aside from the obvious ones like having a 16-core 65W TDP SKU, is that AMD EPYC means we have validation work for server OSes like Ubuntu and Microsoft Windows Server. We also have the validation work to support ECC UDIMM memory. This is not just a certain motherboard manufacturer offers ECC that they are supporting themselves with a Ryzen part. This is the entire line supporting ECC memory from AMD to the OEM. AMD also has the RAIDXpert2 for Server which is the software RAID solution. This matters for some segments if you need to have RAID for Windows Server as an example.
