Admit it. You enjoy engaging with him
In much the same way as I enjoy repeatedly running into walls at speed.

Hey that is FUN!In much the same way as I enjoy repeatedly running into walls at speed.
No thanksAre we ever gonna see a 50-stage pipeline ARM or RV CPU running at 10 GHz?
Do guys pronounce "RISC-V" as 'RISK-Vee' or 'RISK-Five' ?
Coz "V" stands for both the letter 'V' and roman number "V" (Five).Wouldn't RISC-V and RISC-Vee sound the same? I've read it is called RISC-Five but I still read it internally as RISC-V.
Oryon is the brand name of the CPU. It's like AMD's Zen.It seems future Snapdragon 8 will use their own in-house CPU core (Oryon/Pegasus),
Rumour is D9400 has a 3+5 configuration (3× X5, 5× A725).
- Why do Mediatek insist on using 4X+4P (including one extra big core) config in their smartphone SoC which is definitely too power hungry?
What does 4X+4P mean? X = Cortex X, P = Cortex A7xx ??Why do Mediatek insist on using 4X+4P
Where did you get the 4.73 TFLOP number for 8G3 GPU from?
- Why do Dimensity 9300's GPU is so powerful yet due to memory bandwidth constrained that there is virtually no difference in performance between SD 8 Gen 3 and D9300? FYI, SD 8 Gen 3's GPU is having 4.73TF while D9300's GPU is having almost 6 TF.
That doesn't make sense. M4 will prolly upgrade to LPDDR5X-8533. Also as I have commented earlier, full speed LPDDR6-12800 won't be available in 2026, and it's price will be high and volume will be limited.I think Mediatek is preparing to launch SoC for Windows PC as well. By end of next year, Mediatek should launch Dimensity 9500 with 64-bit LPPDDR6 support (extra 33% BW). And this is the same SoC Mediatek going to use as WoA SoC. The CPU config should include one prime Cortex-X6, three Cortex-X? and four A7?0 mid cores. The GPU config should be slightly faster than current one. Of course, both CPU and GPU could clock faster to utilize extra memory bandwidth. 4X+4P is actually similar to Apple's M3 config; ie. we all know Apple 4E cores are way powerful. In fact,
I think every OEMs (AMD, Qualcomm, NV and Mediatek) are all targeting M3/M4 with their SoC with LPDDR6 solution which actually has same memory bandwidth as Apple's 128-bit LPDDR5-6400.
This generation is the first time in a while, where MTK has the more powerful GPU. Qualcomm dominated with with 8G2, 8+G1, and even the 8G1 made on Samsung's disastrous node.Clearly, Mediatek is prioritize more SoC power to GPU performance due to smartphone SoC design.
Waht.Other OEM like Qualcomm might prioritize more onto CPU core counts, for example we might see six Pegasus cores with two E cores.
102 GB/s from LPDDR6-12800 mated to 64-bit bus?No matter what, all OEMs have to work within 102GB/s memory bandwidth. It will be interesting to watch what NV and AMD going to do with their SoC design...
AMD is more likely to follow Ventana and Tenstorrent. The first full-fledged products would be aimed towards Windows Server/Datacenter. Non-ISA components are key to AMD getting customers on RISC-V by AMD. So, eyeball OpenSIL development towards RISC-V Datacenter-orientated AMD processors.I mean maybe AMD plans to release RISC-V cpus oriented for desktop and mobile at some point, but not in the near future.
SOPHGO's SG2380 (P670+Imgtec AXT) is RVA22 + Vector + Vector Crypto which is the baseline for Android/FuschiaOS/ChromeOS.The faster RISC-V SOC i know of is the TH1520 on the Lichee PI4 A trades blows with A72, support on linux is minimal, support on apps is non existant, we are just starting to see that providing arm64 bins is becoming more common, but rv64? yeah, no. Even if RV64 Windows were to come out tomorrow with full x86_64 emulation support who makes the drivers? AMD is going to make the 3rd party drivers too? This is a major issue for ARM Windows.
Huh?Phoenix, Phoenix-L, Phoenix-M, Pegasus etc.. are the core names, akin to Zen 2, Zen 3, Zen 4, Zen4C etc...**
Ok Good Point. We don't know if Qualcomm will use those core names publicly.Huh?
Zen2/3/4/4c are the consumer/brand facing core names.
Each of them has an internal codename too - just as Zen 5 is Nirvana, Zen5c is Prometheus and Zen6 is Morpheus from LinkedIn engineer entries.
I think that Zen4 is Persephone and Zen4c is Dionysus.
Pretty sure that Oryon is their new 'core' branding to replace Kryo Gold/Silver/Bronze which was the v8-A era branding for their own custom core, and the subsequent ARM IP implementations.We don't know if Qualcomm will use those core names publicly
We really need more variance in reaction emojis so I can 😅 to posts like that 🤣And right after the Windows/RISC-V GalaxyBook with an AMD GPU, out of left field comes... Itanium 9900! Back from the dead, now with a large Geforce instantiation on-die!
It's totally happening guys! For realzies! Just like Tunnelborer and Crane and EPIC-V and AMD FD-SOI products and "K9-ified Zen" and N4X Bergamo!
Coz "V" stands for both the letter 'V' and roman number "V" (Five).
I know Roman Numerals. I bet Gen Z doesn't though . I'm just saying I read it it as V ecause it just sounds more natural to me. I know it is wrong.
AMD given the timeframe is more likely to make RISC-V chips.Also why are we discussing RISC-V in athread about AMD making ARM APUs...
The irony.
Are you playing with any RISC-V CPU at the moment?
I do, and it works about as well as ARM does under Linux. Mostly tinker status for now, and yes, SBC performance does need to improve.Would you like to share your story of that experience?
The current profitable niche for RISC-V is to design a custom product for a niche industry (such as AI) and sell it for less than an ARM or x86 solution.Meanwhile, in the real world: some licensable RISC-V cores exist that offer performance only moderately behind current ARM IP, but no merchant silicon; Ventana's numbers have been pretty unimpressive and while they've produced a lot of paper, silicon has been in short supply; Rivos and Akeana are stealth-mode and have released no details of their uarch; and Tenstorrent makes AI accelerators with a sideline in licensable IP.
None of these are coming to laptops any time soon, and RISC-V remains a deeply mediocre ISA with fragmentation problems that are already becoming readily apparent.
Would behoove some folk here to calm themselves, especially when replying to posters with a long history of, shall we say, creative claims.
Maybe if Intel makes a RISC-V product? Thankfully only IFS has been involved. Intel does not have public plans to do anything beyond x86-64.Are we ever gonna see a 50-stage pipeline ARM or RV CPU running at 10 GHz?

Some of the products are quite performant, but end users can’t get them.

Not even a CPU. And you could almost buy a complete Genoa 64 core 192 gig ram setup for that (I did it for $3000)Is this worth $2499? https://www.crowdsupply.com/milk-v/milk-v-pioneer#products
