AMD had announced new Opteron CPU. There will be multiple 64 bit X86 cores inside a single CPU. The product will be available in summer 2002. The NUMA (non uniform memory access) is more suitable for AMIGA DE / AA than SMP (Symmetric Multi Processing). Read it here (http://www.vanshardware.com/news/2002/04/020422_AMD_Announces_Opteron/020422_Amd_Announces_Opteron.htm)

1... It's still x86.
2... "Clawhammer" will be still only 32-bit, and is rumored to be offically called Athlon 64.
3... "Sledgehammer" now offically called Opteron will be the 64-bit CPU.
4... It's still x86. :-P
-
Yes, it is still x86!
BUT, AmigaOS 5 will be able to run on it!

According to the road-map graphic,
The Clawhammer is 64-bit but does not have the MP technology of the Sledgehammer!!
It has the same x86-64 technology as Sledgehammer which is the AMD 64bit system.
Whats even more interesting is that Intel will be using the same x86-64 instruction set!

Duh, yeah, gee, what d'ya know... it is x86.
I mean, isn't it exciting that the processor family that:
1) will have the most bang per buck (not due to efficiency of process but because of its HUGE DEMAND (name me a chip that beats it for money vs power))
2) with the largest share of programmers' experience
3) with the biggest install base
... will be able to drive Amiga applications?
Get over your Intel-phobia guys, AMD is now in charge!

That makes sence? The CPU is more suitable for AmigaDE/AA than SMP? HUH?
-
Jarrody - I totally agree with you. I feel that user base / number fo experienced programmers / bang for buck is the way to go. Most on here however hate the x86 simply because it is Microsofts CPU of choice. I for one, think there is nothing wrong with CPU, it's whats running ON it that is wrong!
Mr. Anon - I think what the most suited than SMP is supposed to mean is that since the single chip contains multiple cores (hence like 4 chips squeezed into one) and the fact that they can all access each others mem is more effecient (programing / space / cost / heat / power - wise) than having to manually handle multiple CPU's all seperate and having to move data to external memory for other's to get their hands on it.

I have no problem with the x86 series of processors. I have always liked AMD as my prime CPU choice for my Window$ machine. However, I have two concerns about this new CPU....
1). If it is doing to have more then one CPU core in it, am I the only one who is concerned about the cooling needed for this? I mean I have a 1.4GHz Ath which has a fair sized 'sink and have seen the size of the 'sink needed for the 2000XP (Let alone the one Intel suggest for the 2.4 P4! Now that is BIG!). What with the ATI AIW's (8500 on) it is now almost possable to have your PC as the center of your audio/video setup. The last thing you need is a box in the corner making more noise from its 5 fans (One it PSU, one on CPU, one on the graphics card, poss one on the chipset and a case fan (or two)) then your vacum cleaner!
2). From the diagrgam on the report it would seem that the cpu needs seperate memory for each proccessing unit. Ok, memory these days it quite resonable, but I assume the memory has to be the same size for each unit, which lets face it could turn out to be expensive when you need more mem!
These days I have given up on the raw speed for PC's, my 1.4 can do DVD-Decoding and with my AIW Radeon, DVD-EnCoding at a good rate and quality. As I very rarley use it for games, (which at the end of the day is really what most home users will more then likely use there machine for) I have no need anymore for a faster CPU.
Just some random thoughts I had on the matter, please pay me no mind :-D
BTW I think it is a shame that AmigaINC didn't go the x86, even if they stayed with one producer (i.e. Asus, cause I know about the chipset problem), you never know, we may have had OS4 by now. PPC is a nice option and I like it, mainly for the lack of heatsink so it will be quiter, but the dev time to make a new board and OS is (as we have seen) a long time

2... "Clawhammer" will be still only 32-bit, and is rumored to be offically called Athlon 64.
What a terrible missinformation!!
ClawHammer IS (or better will be) 64bit CPU.
ClawHammer is a light version of SledgeHammer, the share the same technology.
ClawHammer (aka Athlon 64) will be for Desktop PCs that is why they still use the already well known Athlon brand.
Oh and no it is not x86 anymore, it is x86-64 now. Oh and yes it will kick PowerPC's arse even more now...
Don't get me wrong I am a supporter of PowerPC and that cpu in the new Amiga is very good, but 1+1=2 not 3 or 1. x86 IS BETTER right now.
Now it's the flame time :)

"The product will be available in summer 2002."
Surely the year is 2003?
-
"Shipments of the AMD Opteron processor are planned to begin in the first half of 2003 "
And that is from www.amd.com .
Better read before post.

Mr. Anon - I think what the most suited than SMP is supposed to mean is that since the single chip contains multiple cores (hence like 4 chips squeezed into one) and the fact that they can all access each others mem is more effecient (programing / space / cost / heat / power - wise) than having to manually handle multiple CPU's all seperate and having to move data to external memory for other's to get their hands on it.
This is not true... AMD originaly thought about using dual cores for the Sledgehammer, but this will not happen until they get their 0.09micron fabrication online.. This will be in the second half of next year.
Btw, Clawhammer will be out in October this year, and Opteron(Clawhammer DP and Sledgehammer) will be out in Q1 2003.

I am afraid that you do not know what you are talking about.
x86-64 is a big improvement over x86 architecturally. It now has 16 64-bit general purpose integer registers, 16 128-bit SSE2 registers and 16 general purpose floating point registers - a much better number all-told than x86-32.
The 64-bit AMD platform is split up into 3 products:
- Athlon XP64
- Opteron DP
- Opteron MP
they all have ONE processor core. The first one uses a ~750pin socket, the latter two use a ~950pin socket. The first two have 512KB L2 cache, the latter has 1MB L2 cache. The first only works in a single CPU system (one 800MHz double pumped HyperTransport link), the second has 2 links (some think 3 links), and the latter has 3 links and dual-DDR PC2700 memory busses, whereas the first two only have a single DDR PC2700 bus.
The first one will be available in October/November 2002, the other two around 3 months later.
The platform will work very well in SMP mode, and even better with a NUMA aware operating system.
Motherboards for the single CPU will cost around $200 on release, with a ~$400 CPU.
In 32-bit code, the processor will have IPC 25% higher than the current Athlon processor. In 64-bit mode the IPC will be 35 - 45% higher. A lot of this is due to the reduced latency of having the memory controller on the CPU die, the rest is from architectural improvements.
Yes, this CPU will wipe the floor with any G3 or G4, even if they were clocked at the same speed. AthlonXP64 is going to be released at ~2.2GHz...
-
About time for that G5 I say...
-
Unfortunately, the only major PC vendor who use AMD CPUs is none other than ... Gateway!
DELL never use AMD. IBM, HP and COMPAQ had discontinued AMD based product because of inefficiency in manufacturing. They prefer to use only INTEL CPUs.
-
Someone might be interested about 64-bit PPC rumors:
"Q: I noticed late last year there were a lot of rumors circulating about the G5 but I haven't heard much recently, do you know what the current / rumored time frame for the G5 is?
A:
Just take one look at Steve Jobs' statements from the recent press-restricted shareholder meeting, and you'll get the answer: "we have some pretty good things coming."
In Steve-speak, we're led to believe that this means: we're not going to trample all over the performance issue in one fell swoop, but we're going to continue to come out with systems that widen the gap in certain areas, and catch up in others. In short, the G4 has legs and will move to 1.6GHz+ in the year ahead, along with 400-500MHz high-bandwidth memory. But for those seeking the G5....expect to wait a little longer. It may also not be the processor we are expecting....unless of course Apple passes off the new high-bandwidth G4s as "G5"s."

Personally I think the G4 still has some milage in it. The current G4's (MPC 7455, ie Apollo) are still using a 0.18 micron fab process. When Motorola move to a 0.13 fab process there will be a further speed bump.
PS: The MPC8540 (Currently the only G5, or e500 core processer being produced) uses the 0.13 micron process.

Intel will NOT be using the x86-64. This is a AMD specific extension to the x86 instruction set.
AMD Site (http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_4699_875,00.html)
Intel has created a whole new instruction set for their 64 bit processor. To run x86 instructions they have imbedded a pentium type prucesser into their Mcerd ? chip
-
The estimated speeds up is about 20% faster, than current x86 CPU's.
-
That is why HP and Compaq both have AMD based products being sold, both in laptops and on the desktop.
Stop spreading crap when you don't know what you are talking about.
AMD have very high market percentage in Europe, as high as 50% in some countries.
-
The specification is free for anyone to use however. Transmeta is likely to create an x86-64 compatible chip as well, although I don't know why - they really need to sort out their current processor lines first.
Intel is rumoured to be adding the 64 bit x86 instructions to an upcoming P4 processor codenamed YamHill.
Itanium is a big flop - it has cost Intel around 1 million dollars per CPU shipped so far - shame they are charging less than $10k for each chip. It doesn't look like they are going to get much further either - there is a big resistance to the technology (messed up VLIW implementation that compilers have a lot of difficulty optimising for) in the market. Itanium 2 will be released this year at 1.2GHz - maybe it will do better and perform better. But it is not x86 compatible, and people have x86 applications they want to run on their servers. So the choice is not hard really.
-
This is a GREAT news!!
Can I run Sheep on this in the future?
I hope Amiga supports this.( and IBM's multi-core)
The IBM multu-core will be FOUR G3 chips shrunk down into just one. Will it be better than this? I can't thank Amiga.org enough for keeping me informed.
Fantastic job! Important info.
