AMD Zen 4 CPUs Rumored On Track For 2021 Release
- tus88 7y agoHolding out hope for PCIe5 and DDR5 too...
- nobodyshere 7y agoI wouldn't count on it. There aren't even that many pci-e 4 devices on the market.
- mattashii 7y agoIntel is planning for PCIe5 in 2021 (skipping on PCIe4), so AMD having gen 5 support in that generation would not be too unexpected. Though with the seperation of IO/compute dies I would not be suprised if PCIe5 would only appear in EPYC/Threadripper components. I expect that the upcoming Ryzen socket refresh (AM5, which is expected to come with Zen 4/Ryzen 5xxx) to have support for (or even require) DDR5, as by then DDR5 will already be available for a year.
- wtallis 7y agoIn the server market where the extra bandwidth is actually useful, the transition from PCIe 3 to PCIe 4 is pretty far along. Switches, NICs, SSDs and FPGAs supporting PCIe 4 are all either available or announced, and server-class GPUs should also show up next year. Most of those products have good reason to continue on to PCIe 5 as soon as suitable hosts are on the way.
- NullPrefix 7y agoPlenty of gen 4 SSDs on the market
- bryanlarsen 7y agoThere was less than two years between the release of the two standards, so two years between the release of supporting CPUs wouldn't be surprising.
- shmerl 7y agoI'm more interested in HBM memory becoming cheaper for GPUs.
- philjohn 7y agoThat's what HBM 3 is meant to accomplish.
- hajile 7y agoI want HBM for CPUs. It's faster, lower power, and lower latency. The only potential downside is being harder to upgrade, but I think that could also be handled with some work.
- arcanus 7y agoHBM is not lower latency than traditional DDR. It is significantly higher bandwidth, but the latency can be higher. On GPUs this is not a problem, because they are quite latency tolerant. CPUs might have more trouble hiding the latency impact.
- hajile 7y agoYou are correct about HBM2 (latencies between 12 and 16ns vs 8-12ns latencies in typical DDR4 systems). My understanding was that HBM3 reduces those latencies and HBM4 potentially reduces them even further (in addition to lower latency due to closer proximity). AMD seems considers HBM on-chip to be an upcoming reality. https://www.guru3d.com/news-story/amd-working-on-vertical-(3d)-stacking-of-dram-onto-processors,2.html https://www.guru3d.com/news-story/amd-working-on-vertical-(3...
- einpoklum 7y agoOk, then - expect to wait at least 5 years, maybe more. PCIe 4 was standardized in 2011 and it's still not that widely adopted. So let's say 9 years from standardization to wide availability. PCIe 5 was standardized in 2017... 2017+9 = 2025. Good luck.

- m0xte 7y agoVery cool. For me this hopefully means higher end Zen 3 CPUs will bomb in price so I can upgrade my 2600X
- Mirioron 7y agoI'd first like to see what Zen 3 CPUs are like though.
- PedroBatista 7y agoCurrent Intel is so f#%$ed! Either someone at the company has the power and knowledge to make deep foundational changes or not even their size and “business prowess” will be able to maintain the current structure and culture.
- tyingq 7y agoThe note that Huawei's Hisilicon is one of the three customers for TSMC 5nm is interesting. The US trade ban is still in effect for Huawei. If we don't lift it, we will likely be blocking out the fastest Android.
- DiabloD3 7y agoHuawei is accused of state-sponsored spying using their position as a major LTE backend equipment vendor. I don't think worrying about who has the fastest Android phone is important here.
- tyingq 7y agoI wasn't trying to make a political statement. I just wasn't aware Huawei was able to get in as one of the only 3 customers. It seems to position them well versus Samsung, Google, etc.
- tiernano 7y agoAccused, but still no proof, right?
- ethbro 7y agoIt's not actually been accused, has it? The proposed rules are on the basis of hypothetical future spying capabilities. (Personally and technically, I don't think the ban is a terrible idea. Non-audited software, from a country without an independent legal system, running on privileged network hardware seems a reasonable concern. Especially deployed by rural ISPs who can't perform security due diligence. Even if the public debate is being framed poorly)
- tyingq 7y agoIt is at least not hypothetical for the US. https://arstechnica.com/tech-policy/2014/05/photos-of-an-nsa-upgrade-factory-show-cisco-router-getting-implant/ https://arstechnica.com/tech-policy/2014/05/photos-of-an-nsa...
- shpongled 7y agoPerhaps 2021 will be the year I upgrade. I've been rocking an i5-4690k stably overclocked at 4.5GHz for the past 5 years without issue, but I'd like to get some more threads
