Intel

11th gen is a bit of a dumpster fire. High end is really dumb. Mid range is priced competitively, especially 11400F which doesn’t have direct competition from AMD right now. This is currently the budget king.
Intel Xeon 3rd gen Scalable (Ice Lake SP) now offers 40 cores, lower price, 64 PCIe lanes, 270W TDP, 4TB RAM support, and 10nm process.

Intel’s Future

2021
- Q4 – Alder Lake not confirmed if that’s mobile or desktop variants, a whole new approach. Golden Cove + Gracemont cores, similar to ARM big.Little – Intel “Hybrid Technology”
- 10nm Enhanced Super Fin
- PCIe Gen 5 support, DDR4 and DDR5
- Up to 8 Golden Cove, 8 Gracemont cores
- DMI Gen4 (up to x8)
- X16 PCIe 5 lanes to CPU, x4 PCIe Gen 4 to CPU too
- Thunderbolt 4 “USB 4 compliant”
- LGA 1700 – 500 more pins!
- Will support 4800MHz DDR5, or 3200MHz DDR4
- Z690, high end boards will support DDR5, lower end options will support DDR4 like Skylake.
2022
- Raptor Lake – refresh
2023
- ‘7nm Enhanced SuperFin’, same design, new version of perf cores, same socket

AMD

Ryzen 5000 is killer – and now everything but 5900X and 5950X are in stock
- Likely due to single vs dual chiplet. Easier to make 2 5600X’s than 1 5900X
5600X currently lowest end option, leaving a big gap for Intel’s i5 lineup. 11400F looks very hard to beat for value, so AMD need to offer a 5600 non-X if they want to compete.

AMD’s Future

2021
- Threadripper 5000 launching in August – Zen 3 arch (maybe Zen 3+?). Expected the same 19% IPC uplift, better clock speeds, same core counts.
- Zen 3+ – refreshed Zen 3 arch, rumour says ‘more IPC uplift than Zen -> Zen +, but not much more’ so 4-7% more. Decent, not amazing. Hopefully more SKUs available!
- Zen 3+ is due to be on TSMC’s N6 node, which is smaller but not a “true new node”
- Interestingly, apparently it may be on AM5 still as it has a revised IO die which may use DDR5 – not the same IO die as Zen 4, but more similar to that than Zen 3’s.
- Zen 3+ due out Q4 2021 apparently
- Z570S – could be refreshed version for Zen 3+, or potentially more likely a revised version of the chipset with lower power ‘S = “Silent”’
2022
- Zen 4 – TSMC N5, quoted IPC of 25%, total perf uplift of 40% thanks to higher clock speeds.
- Leak says Genoa EPYC chip (zen 4) was 29% faster than Milan EPYC (Zen 3)
