even considering two processors at once?
Thanks a lot, KTE. ;)
Now, the only question for me is: what will be the HT version of FASN8?

Yep. The figures of around 260W sustained peak draw were dual socket Opty 2350 with 12x 15k SAS in RAID 0 using a RAID storage card and 8x1GB RAM (Disk, RAM and CPU being loaded). 400W 80%+ efficient PSU is roomy enough, unless you'll be adding vid card, in which case, a little higher is better (esp. if both oc'd).
No idea of FASN8 (that would require more power by design).
You're welcome :)
I assumed, that you refer to Johan's cache ping pong test. One of your later postings confirmed this. Well, I followed the development of this test on the original aceshardware forums a while ago and many ideas have been discussed back then. You can find the full discussion and an early version of the code here:Quote:

First I have to say, that this special test is referring to a special variant of core to core communication. And here I think, that K10 got a performance hit in this benchmark due to it's write buffering and maybe even L3 cache (which BTW adds ~20ns to mem latency in case of a miss). This benchmark doesn't tell us anything about how fast a core can access data in another core's cache, which was not written right before this access but at least tens of cycles earlier. Except for semaphores and the like such an access behaviour would just stand for a bad multithreaded coding style. ;)
SSE(2) instructions are mostly being double decoded on K8. SSE was vector decoded on K7. Since these 2 separate ops for both register halves on K8 finished one half one cycle earlier than the other half, it led to a nice 4 cycle latency for standard ops (add, sub, mul).Quote:

But as pointed out in the past (google for "k8 sse bottleneck"), there was a strange behaviour regarding SSE loads as you can see in the tests here again. Maybe due to the double decode, it was necessary, that such a decoded instruction uses a single FP unit sequentially. While using x87 or MMX loads it was possible to load two 64 bit values per cycle, this was not true using aligned 128 bit loads resulting in 0.5 SSE loads/cycle. This has been solved (maybe simply by avoiding the double decoding) - leading to a quadrupled SSE load performance compared to K8.
Really enjoy your posts here, they're very informative and always a nice addition to the forums :up:Quote:

BARCELONA NEEDS HELP FAST.
Apparently Barcelona will not work in older Mainboards, OLDER Meaning Yesterday & Today & for some time, as it useS multiple voltages at same time, in core, so its input pins are also multiple ?, anyway, due to unique Voltages simultaneously in core, there are no Mainboards, AT ALL.
Testers Stuck Pair into tyan 29XX, No Go, took working system & stuck in Barcelona & 50% lower scores than opteron dual cores. Thats BIG PROBLEM, I think.
Maybe its simple Hardware Socket or just rewire/upgrade of controllers, YET What if Barcelona internal CROSSBARS are all tuned wrong to put out such slow output.
extra!!!extra:kb940520 tests redfiboost/butt locker. Get it ,,ha.ha.ha?ah.

This slowdown is handicapping the fanboys to brag about barc for least...:)
This was just someones comment about the new AMD roadmap that the inq posted. It was listed in the comments section. Who knows what validity it has.
Yes, its not news its a comment, point is all in all its a big lengthy delay,it holds the same validity as some one ranting in these forums.
But being a dual socket Opteron user its a frustrating experience.
my 2 cents
OEM's get their chips months or atleast weeks before launch but not able to see a decent working board after weeks of launch is the problem,forget about benchmarking and losing crown kind of stuff.
Stabilizing takes time its ok, but minimal working should not.
Problem is with board makers or BIOS writers or with barcs or combined ?
PS: Nothing against you Phil,its an AMD chip buyer/little fan frustration.
Maybe be true, but what I know is that we haven't seen one run correctly on this site. I suspect that the two main reviews that I have seen had them running correctly and I would imagine that there are AMD customers that have Barcelona systems running. I also believe that there are significant problems with the present platform.
I'm not sure what the problem is here, but I suspect its mainly because we're just a little farther down the food chain then Dell, etc. AMD's support is too busy stamping out fires elsewhere.
No offense to Dave, Steven, etc who have worked hard to give us some insight.
In the end, I do believe the writer is correct in sense that the present mb do not work well with K10 and we will not see the full potential of this cpu until new mb are designed. Unfortunately all of those who thought they could just buy the cpu will have to get a new mb as well. I'm glad I just upgraded my 939 and waited.
PS. No offense was taken and I'm frustrated as well
Hypothetical situation:
What if Barcelona is actually all it's cracked up to be, and a little more. What kind of demand would that cause for these chips? What if the supply couldn't fill demand, considering the HPC and supercomputer obligations AMD needs to fill first. My guess is the backlash from that would be as blown out of proportion as the situation now, if not worse.
I imagine AMD is ramping %110, and their first priorities are getting these chips into the hands of the big contractors who already signed for them. I'm sure that is much more important to them than worrying about keeping a handful of enthusiasts happy. After all, these are server and HPC chips.
Just, what if...! :D
The doom and gloom makes me :rofl:
Oh, I'm not gloom and doom, just frustrated. You did notice that I said we wouldn't see the real potential of these chips until we had better mb. I meant that in a very positive way.:up:Quote:

For sure, OEM's and super comps are their priority and thats where they make bucks its a business fundamental.Quote:

Reminder: Its not about AMD and chips,its about boards and BIOS.
Topic here is not getting a decent board out,informing the same repeatedly to others,not a kid saying as AMD gone or some less mature remarks, and also note that HPC and super comp manufacturers wont read AnandTech or XS to buy chips/boards and wait for bench marks. :)
Here it is all about small biz owners,retailers for small clients. enthusiasts buy C2D Quad no offense.
If some one thinks ALL here are a bunch of enthusiasts play games using dual socket opterons,then one may need to rethink.
Well, lets hope that it goes the way you've stated it. Either way I think Phenom is going to do a little better than the nay sayers predict.Quote:

It means nothing more than what we already know.
There's no doubt Family 10h has been a disappointment and pure source of frustration up until now and even worse with the future roadmaps all being so badly delayed. No dual core, no tr-core, and no FX till at least March 08, means the FX 3GHz shown in January will not even be released 18 months from the marketing. What a bad shambles that is. Then you have crap MB and BIOS issues. :(
Under normal circumstances, that's exactly how things should work but this time it didn't go as smoothly as planned. As you may or may not have heard, there was a HUGE problem with yeilds on the first run of Barcs. This problem wasn't something which was easily remedied, but ultimately things got fixed. In the meantime, AMD had fallen months behind schedule and instead of delaying the launch any further, the "original revised" launch date was still targeted. This resulted in an insanely short development time for even AMD's largest oem clients. TBH, I wouldn't be surprised to hear that mobo manufacturers were shipped samples as late as a few weeks before launch. IMO, Barcelona is a polished processor - probably exactly how AMD had originally planned it. The issues we're seeing involve compatibility with current mobos. The bios developers can't be blamed either as tey attemped to squeeze what normally takes months of testing into a period of a few weeks. I'm confident that things will sort themselves out in the coming weeks and we'll finally see what k10 is really capable of.Quote:

Hammerhead? I don't remember what that is...
I think its the RD790 mb.
come on steve, give kribibench a run! :D

I like me some shark!
Read the whole thread!....
It only took two days. S7e9h3n, you mentioned that the new bios you've acquired (I won't even ask ^_^) work, but you've had no luck with the opterons still :-\ Do the bios you have on hand leave the old options for overclocking on the L1N open? Have you had any luck at all getting either CPU to boot?
I really appreciate the numbers you've thrown up, as well as everyones' contributions of information regarding these chips.
Must...have....this........mobo :bounce:Quote:
