I think MLID is also confused about utility of the LP cores in modern client computers. Their role is to keep the lights on the PC, while in idle and light loads, and allowing the full speed core complex to shut down.
What is not the role of the LP cores is to meaningfully add to Cinebench scores. Usefulness of the dense cores, like Zen 6c is to improve the Cinebench benchmark, as their primary role.
There may be a whole new role for the LP cores in server environment - as alternative to Arm cores, for very light loads, but that is unrelated to client.
100% agree!
If there is a market for a VERY high count processor, with low computing requirements, I still wonder if a Zen 6c isn't a better use of silicon space than an LP core. After all, Zen 5c gets 1.4x performance from SMT. So it seems to me that you would likely have to have an LP core that was 1/2 the size of a Zen Xc core for an LP core to make sense.
I think the high end Nova Lake variants will have some LP cores, so we can see how that works out.
If you would deliver arguments instead of 1-liners without any meaningful content....
Funny, I made the same comment a couple of weeks ago for the same poster for replies of "No it isn't" and such. At the time I said that we should just go back to the "My dad is bigger than your dad" line of discussion as it is equally stimulating .
I think the way the discussion is framed i.e. moore's law etc is kinda outdated. maybe that's the point around saying moore's law is dead.
I agree. Perhaps we should be talking about the performance / $ vs. the density of transistors? As mentioned, there are many ways to increase performance that do not include transistor density. This is particularly true for specialty instructions and processors.
There will be always be some who want "more" (and they are wildly overrepresented on a site like this one) but there will be fewer and fewer of them as time goes by, unless some new "killer app" appears that causes some of those who for whom today offers them more than enough to suddenly say "I can't buy anything today that gives me everything I need/want".
I agree that as time moves forward, it seems that the % of the market that needs more for that "killer app" is decreasing. This is also my argument for very high core count desktop processors. We are approaching the point where you can put so many cores in a socket that you easily over-run the ability of RAM to feed them in highly threaded apps ..... and there simply aren't that many of those or people that use them (Mr. Hulk being one of the exceptions of course ).
I actually hold a degree in EE, but in the Navy, I was a nuke mechanic .... so kind of a strange bird.
Some understanding of the theory behind equations, tables, software, helps to avoid "garbage in, garbage out" mistakes I think.
I agree. I just think that College overdoes the math and algebra at the expense of focus on theory and why things behave the way they do. Too many engineering students spend 90% of their thought on the calculus and algebra and 10% on how to setup and solve the problem.
Yes, the manufacturer had done the calcs using FEA but my boss wanted to me to get an "estimate" by hand to check those numbers.
In the Navy nuclear power program all engineers were taught thumb rules and general theory so that you could quickly assess what you were seeing in the instrumentation and be able to determine causes through intuition. Lots of thinking on your feet instead of thinking on a computer.
Way back I interviewed for a job at Princeton Plasma Physics. I thought it'd be cool to work on fusion development.
LOL. I worked my way through college at UIUC by working with post docs in the Fusion Studies Lab where I did work on the dense plasma focus fusion propulsion program and the Tokamak hydrogen pellet rail gun fueling system . Lots of plasma physics and lots of fluid modeling on the CRAY .
Now I pontificate on microprocessors!
Me too .
I do a lot of audio stuff and can hear to about 12kHz these days. Most of the "high end" in audio is actually around 8kHz or maybe 10kHz.
I have been playing in a band since high school. My right ear (the one closest to the drummer when I was in my first band) doesn't do much over 10kHz I think. Left ear is ~14-16kHz though. I do mostly live audio, but make some live recordings and post process them for band videos.
I could see something like 12 Zen 6 cores on one chiples and 18 6c on the other chiplet.
That would be a very interesting combination.... so 30c, 60T. Do you think that will be enough to overcome the Cinebench scores from the Nova Lake 52 core? It really only has 48 cores that can breath well enough to push any CB scores though IMO.
I have been hearing more lately about AMD's new memory controller setup on Zen 6. Can someone please comment on how you see having 2 memory controllers vs 1 might help with bandwidth and or latency over the current single memory controller and dual channel configuration?
