A few days ago, Intel officially announced the postponement of the start of production of the key generation of Xeon processors Sapphire Rapids from the fourth quarter of 2021 to the first quarter of 2022 and confirmed the start of large-capacity production in the second quarter of 2022. He further stated that the so-called Sapphire Rapids HBM, ie the version of the processor equipped with HBM2E memory, will not be released immediately, but later in 2022.
However, according to unofficial information, it is not very realistic that the variant equipped with HBM memories could enter the market next year and it looks more like a postponement to 2023. Although these rumors contrast significantly with the official statement of Intel, it would not be the first time Intel officially admitted one postponement only when de facto another postponement has already taken place.
The YouTube channel AdoredTV, which is not known for the stable quality of its forecasts, this time brought information based on leaked materials from Intel, so it is worth paying attention to them:
First of all, here we have a roadmap of Xeons, which puts Intel products in time with Epyca from AMD (last line). This roadmap is older, as release times are highly out of date (eg Xeons Ice Lake they are painted for the fourth quarter of 2020, while they are only now entering the world, with the turn of spring and summer 2021). Although the roadmap may be about 3 quarters old, it still tells us a lot of interesting things. Intel, for example, assumed that Sapphire Rapids will be launched at the end of this year, when it will not have a stronger competitor than Epyc Milan. In contrast, it had a combination of higher beats (350W TDP versus 280W at Milan) and ~ ~ 20% higher IPC to achieve higher overall performance. He saw such a scenario as an opportunity to return to the performance throne. This scenario does not occur with normal availability Sapphire Rapids will wait about a year (from now on) when it will be on the market Milan-X with a layered v-cache, which probably won’t be faster, but certainly won’t give Intel room for some competitive rolling, tearing of asphalt, or other road works.
Like Sapphire Rapids delayed by two quarters, so it will probably move by two quarters as well Sapphire Rapids HBM, which, according to available information, will not look at the market until 2023. Unlike the generic version of this Xeon, it will only support dual socket systems. He will be the successor Emerald Rapids, which has been talked about for just over half a year. It was supposed to be added to the roadmap shortly before, and most sources aren’t sure what’s going on. According to the editor of the SemiAccurate website, this is basically Sapphire Rapids-refresh, respectively a corrected version of the original Sapphire Rapids, which the source refers to as a “hot buggy mess”.
As for the representation of AMD products, it is, of course, Intel’s view. Intel says it would Epyc Genoa (Zen 4) was supposed to have up to 128 cores, but according to more recent information, the situation should be slightly different. Genoa to be released as a 96-core product. 128-core Zen 4 it should also exist, but it should be a slightly different product (whether about a half – generation Genoa or a semi-custom product for some supercomputer, we don’t know yet). Regardless of the nomenclature and classification details, however, Intel knew of the possible existence of a 128-core Zen 4 already (at the latest) last autumn.
Other slides compare Intel Sapphire Rapids against the current Epyc Milan (left). although it is clear that when the chart was created, Intel relied on tailor – made tests for Sapphire Rapids (the leads are on average ~ 10% higher than would correspond to tacts and IPC), there is no doubt that a year newer Sapphire Rapids was on average faster than Milan. In reality, however Sapphire Rapids will not come out until Milan-X with v-cache, which Intel apparently had no idea existed.
The right slide compares Sapphire Rapids with 96-core Epic Genoa (Zen 4). Intel was aware that it would lose significantly compared to it, which it should partially compensate Sapphire Rapids HBM.
