About processors Milan-X thanks to leakers we heard for the first time in May. AMD CEO Lisa Su, who told the JPMorgan conference at the conference, said that layering and encapsulation of 2.5D / 3D chips are key elements in achieving the next generational shift in performance and that more information will be released in the coming months.
But maybe that was a bigger surprise when at the beginning of June the head of the company at Computex demonstrated – not at the server Epyc – a layered cache on the desktop Ryzen. In addition, claiming that the product will be released at the end of the year. Epyc with a large cache was a surprise, but given the segment quite a logical solution. The use of new technology directly in the desktop, which, with typically lower margins, is less suitable for the introduction of new technologies, no one expected, advised or speculated about such a method of deployment.
However, questions began to arise as to whether Milan-X it actually exists (Su servers didn’t mention it) and whether the markers just misinterpreted the information about the deployment of the layered / vertical / V-cache. It is now clear that Milan-X is in preparation just like the desktop Ryzen with V-cache and, in addition, that it will be available in four models:
| Epyc | I d. / train. | rate | cache | TDP | price |
|---|---|---|---|---|---|
| 7773X | 64 / 128 | 2,20 / 3,50 GHz | 768 MB | 280W | ? |
| 7763 | 64 / 128 | 2,45 / 3,50 GHz | 256 MB | 280W | $7890 |
| 7713(P) | 64 / 128 | 2,00 / 3,68 GHz | 256 MB | 225W | $7060 / $5010 |
| 7663 | 56 / 112 | 2,00 / 3,50 GHz | 256 MB | 225 W | $6366 |
| 7643 | 48 / 96 | 2,30 / 3,60 GHz | 256 MB | 225W | $4995 |
| 7573X | 32 / 64 | 2,80 / 3,60 GHz | 768 MB | 280W | ? |
| 75F3 | 32 / 64 | 2,95 / 4,00 GHz | 256 MB | 280W | $4860 |
| 7543(P) | 32 / 64 | 2,80 / 3,70 GHz | 256 MB | 225W | $3761 / $2730 |
| 7513 | 32 / 64 | 2,60 / 3,65 GHz | 128 MB | 200W | $2840 |
| 7453 | 28 / 56 | 2,75 / 3,45 GHz | 64MB | 225W | $1570 |
| 7473X | 24 / 48 | 2,80 / 3,70 GHz | 768 MB | 240 W | ? |
| 74F3 | 24 / 48 | 3,20 / 4,00 GHz | 256 MB | 240W | $2900 |
| 7443(P) | 24 / 48 | 2,80 / 4,00 GHz | 128 MB | 200W | $2010 / $1337 |
| 7413 | 24 / 48 | 2,65 / 3,60 GHz | 128 MB | 180W | $1825 |
| 7373X | 16 / 32 | 3,05 / 3,80 GHz | 768 MB | 240W | ? |
| 73F3 | 16 / 32 | 3,50 / 4,00 GHz | 256 MB | 240W | $3521 |
| 7343 | 16 / 32 | 3,20 / 3,90 GHz | 256 MB | 190W | $1565 |
| 7313(P) | 16 / 32 | 3,00 / 3,70 GHz | 128 MB | 155W | $1083 / $913 |
| 72F3 | 8 / 16 | 3,70 / 4,10 GHz | 256 MB | 180W | $2468 |
All four models, regardless of the number of cores, should be equipped with 768 MB L3 cache. This is possible (assuming that each chip has an extra 64 MB stacked) only on the condition that, regardless of the number of cores, each Epyc will have all eight processor chipsets. In the case of the 16-core Epyc 7373X, each chiplet would have only two active cores, but a complete on-die cache (32 MB) plus a layered 64 MB. So (32 + 64) × 8 = 768 MB.
At the end of August, a 64-core Epyc 7773X for $ 10476.99 appeared in one retailer’s price list (the same retailer offered the standard Epyc 7763 for $ 9424.99). Only 10% more than the classic model, on the one hand, is a minimal difference, which seems suspiciously low. On the other hand, it is about $ 2,500 above the official recommended price of Epyc 7763 (a third higher), which may not be far from reality. However, there is still plenty of time until the release, so the final price does not have to be determined by far.
It can be assumed that Milan-X AMD will begin shipping later this year or early next year.
