Guess it is time to jump on them HBM2/2e/3 memory graphics cards. Oh wait...

The leading edge node for FinFETs are High Performance first, and low power really late. N12e => https://n12e.tsmc.com/english/dedicatedFoundry/technology/N12e.htm Didn't come out till this year, 2020. FinFETs are always high performance first, and low power last. Hence, the high current and...

Oof.. three plus years ago: 2018-2019 product all the way in late 2020. Since, SOITEC still has 12FD wafer in development might be a while till 12FDX. Even more longer for 10FD/7FD wafers to finish before we see 7FDX or what not.

Or, all Zen3 and RDNA2 products in the mainline are the 6000-series. Examples: Ryzen 9 6950X = 16-core Vermeer Ryzen 7 6700X = 8-core Vermeer RX 6900XT = 80CU Sienna Cichlid RX 6700XT = 40CU Navy Flounder RX 6500XT = 24CU Dimgrey Cavefish Ryzen 9 6900U = 8-core Rembrandt+16-CU RDNA2. (H-model...

It isn't much of a sudden shrink. N7+ was finished in mid-2018 at TSMC. N5 was finished in early-2019 at TSMC. N7+ at TSMC was getting a lot of flack as being bad. With most of customers cancelling their orders for N6 for non-cadence products and N5 for cadence products. N7+ was projected to...

Leaked roadmaps are all over the place. I assume AMD wants to catch people or something. Vermeer is succeeded by Raphael <= Unicorn succeeds this. https://www.art.com/products/p22111612129-sa-i7615444/leonardo-da-vinci-lady-with-a-unicorn-c-1480.htm &...

SP3 -> SP5 AM4 -> AM6 FM3 -> FM5 New sockets skip two. AM5 socket = FT5 BGA, AM5 is the successor to AM1. Warhol replaces Dali & Pollock and these range of parts: https://www.amd.com/en/products/apu/amd-athlon-gold-3150g https://www.amd.com/en/products/apu/amd-athlon-gold-3150ge...

Yep, they did it with Kaveri/Godavari and Carrizo/Bristol. Kaveri/Godavari => FM2+ (A10-7850K/A10-7870K) Carrizo/Bristol => AM4 (A12-8870 Pro/A12-9800) For desktop: Zen3 is an offering to legacy, Zen4 starts the new socket and supports Zen5(potentially, Zen6&Zen7 as well).

AM4: Summit Ridge, Pinnacle Ridge, Bristol Ridge, Raven Ridge, Raven2, Picasso, Matisse, Renoir, Dali, Vermeer, Cezanne. One generation? It's practically AMD's longest supported desktop socket. Excavator -> Zen -> Zen+ -> Zen2 -> Zen3. All the information I have been loaded with... I can say...

Later model is this meaning: Family 19h Model 40h-4Fh => Rembrandt Family 19h Model 50h-5Fh => Cezanne Cezanne is a later model than Rembrandt. But, it doesn't mean Rembrandt will come out sooner. If and using the given Rembrandt is 5nm with Models 40h-4Fh, then Models 50h-5Fh which is...

Zen3 + Vega-H(Arcturus' Vega name) as indicated in a previous post are 5nm in CPU and GPU form. Thus, Cezanne which re-uses that IP must be on the same node. Van Gogh/Mero which is Family 17h Models 90h/98h respectively is related to the Xbox Series S. 8 Zen2 cores + 24 RDNA2(Navi2x-derived)...

TSMC 7nm EUV can be compatible with 5nm EUV. 6-track 57-nm poly pitch must be used in both designs. 57-nm poly pitch confirms the M1 metal layer = 57 * (2/3) => M1 with ~38-nm metal pitch. 7nm+ with 57 poly-pitch and 5nm with 57 poly-pitch have the same M1 metal pitch. Means the design is...

It is a bit weird, but there is a bit of nuance. All 7nm+ products are on 5nm. It all started with a codename list on an AMD profile 7nm/6nm/5nm Renoir/Durango/Rembrandt Renoir is an APU that has launched Durango is a name of a city like Bixby/Promontory. Rembrandt is an APU and it is beside...

b4b = Be Fore Ban, btw. Hi1630 and Kirin 1000/1020 is still planned to launch. So, they retrieved their orders sometime ago. GA100 826 mm2 => rumor mill it is HOGGING all the wafers!

Why would they AMD is selling. Unless, the intent is do as Japan and buy 5nm products and sell them at a loss. That amount of commitment implicates that TSMC might as well just buy AMD.

N5 Q1+ 2020 shipments => AMD, Apple, Hisilicon(b4b), Bitmain (Phase 1 customers) N5 Q1+ 2021 shipments => Mediatek, Nvidia, Qualcomm, Intel (Phase 2 customers) There is multiple rumors but AMD is the one buying most of N5. Apple rumor => 45,000 wafers per quarter. AMD rumor => 60,000 wafers per...

It is a possibility. 5 Oct 2018: https://community.cadence.com/cadence_blogs_8/b/breakfast-bytes/posts/tsmc-oip-report?pifragment-1779=2 "N5 is ready for design starts. EDA V0.5 certification is done, with V0.9 ongoing (to be complete in November). Foundation IP (standard cells, SRAM, GPIO...

Excuse me? https://www.sifive.com/cores/u84 U74 = A55 in performance U84 = A72/A73 in performance https://www.anandtech.com/show/15991/hot-chips-2020-live-blog-alibaba-xuantie910-riscv-cpu-300pm-pt XT910 is also on-par with the U84 against A73. However, it uses the RVV extension and is capable...

FPU's aren't part of the core. K7 doesn't have a FPU in the core. K8 doesn't have a FPU in the core. Greyhound doesn't have a FPU in the core. Husky doesn't have a FPU in the core. Bobcat doesn't have a FPU in the core. Jaguar doesn't have a FPU in the core. Zen doesn't have a FPU in the core...

Time to escape from ARM, and flee to RISC-V!

Why buy an Atari VCS? Why buy an Xbox series S? Btw, both are using processors from AMD's mainline.

5nm V1.0 went volume in March 2020(within Q1 2020, with a ramp in Q4 2019). What is going into volume in Q4 2020 is V1.1 "N5P".

AMD should be on something that has the density of Intel's 7nm sooner than Intel. Genoa, Raphael, Rembrandt should be on a TSMC N5 process which is comparable to Intel's P1276/7nm.

Family 17h = Zen to Zen2 Family 19h = Zen3 speculatively to Zen4. It is very much likely going to be an architectural overhaul within that of Bobcat to Jaguar overhauling at least...
