Still has the bug? Dam, why is AMD even bother?

Who cares? Unless your running Vmware 24/7 the bug won't affect you.

Didn't one reviewer have constant crashes trying to do a Photoshop benchmark because of this bug? You don't need to be running VMWare 24/7 you need to just be eating up a ton of cache was my understanding of it. You could do that just multitasking.

they did bfdd, they were unable to complete even a single photoshop benchmark... now it wasn't crashing on loading photoshop. But their benchmark involved something that would trigger the crash. (photoshop has batch configurations... which I use often...)

Tech Report couldn't reproduce any issues, but did report that the person having trouble may have been using a BIOS that wasn't up to date...

um, doesn't the t the up to date bios simply contain a non disableable workaround that disables parts of the CPU preventing the crash, and slowing you down by 10-20%?

No. IIRC, the article I read was saying it was a BIOS that didn't handle Phenom yet - i.e., there's a K8 version, a Phenom-unpatched version, and a Phenom-patched version, and the site having trouble used the K8 version. Tech Report had no issues even with the Phenom-unpatched version.

What??? Just because a mobo isn't on the recommended list doesn't mean it won't work with Phenom...those are just the mobos that AMD has certified to now (there are many more that aren't on the list but still work fine).

I am reading good reports about these Phenoms clock for clock with Intel's Quad cores, but not believing them. The Intel's offer much more value in terms of overhead room. It's funny watching AMD's stock since hearing about rumored collaboration with Big Blue. I just hope it all stays interesting...

clock for clock no but im sure the price makes up for it. kinda get what you pay for.

Seem as if the TLB bug is AMD's own version of Bigfoot. Everyone has heard about it, no one has ever seen it.

Which ones, specifically? Tom's looked, but couldn't seem to find them. Notice the name of the article, btw?:)

All I know is that my motherboard is not on the Phenom-compatibility list and it looks like Abit won't be changing that anytime soon.

AM2 is the new socket 939!

I'm not sure I'd be in the market for a tri core I can't unlock at any price. As an enthusiast the E8400 or E2180 or even 5000x2 black appeal far more. And if I needed more cores on a budget (which shockingly enough is the case), the X3210 is without a doubt a much better CPU in every way, and doesn't cost a whole lot more.

When viewed from a whole system standpoint the price difference between all consumer CPUs is not that great. Doubly so if we're talking about an enthusiast (read: high quality, high buck) component build. A barely overclocking low speed tri core just doesn't solve any problem which doesn't already have a better solution -- it's not good enough for server applications and simultaneoushly 'too much' and 'not enough' for desktop apps.

Now, OEMs and a price point < $100 is a whole different ball game.

Yeah. Sucks. All the hype about Phenom being compatible with existing AM2 boards seems to have fallen mostly flat.

AMD is on life support. They desperately need a competitive product, and soon. Losing the performance battle so completely causes severe devaluation of their ASP. If their best product barely equates to a $270 Q6600, it wrecks their ability to sell at any higher price period, and the bulk of their product is forced to sell at discount bin prices (with a massive die and probable low yield to boot).

Bleh.

Stop overhyping that very rare bug people. Its a one in a million shot of anyone even getting that error.

And besides, show me one Intel CPU or other AMD cpu that doesn't have a bug? It completely impossible to create a bug free cpu or even os.

So the bug should be no reason Not to purchace a cpu. Price/Performance/Watt should be involved in the purchase process.

Anyways, depending on the price, like $100 or so, I will get one and may even start building them for my customers. We will see I guess. :)

Actually, not many AM2 based mobos have Phenom BIOS support at this stage. Phenom is backwards compatible with AM2 but without BIOS support that point is moot. It's a sad state of affairs but understandable from a manufacturers perspective - they want people to buy new AM2+ mobos for Phenom, not keep their existing AM2 mobo for another 2 years or whatever.

Tell me about it.

While you have a point, it makes very little sense for an AM2 owner to ditch his/her/its current AM2 board just to pick up an AM2+ board and a Phenom. At that point it would be easier/more sensible to go to the Dark Side(tm).

I'd love to pop an Agena, Kuma, or Rana chip in my NF-M2 nView but that ain't gonna happen anytime soon, if ever. Le sigh.

Looks like it, though with AMD extending the life of K8 on its roadmaps, it looks like AM2 has a little bit of life in it yet. Just not a whole lot of it.

Well, Phenom is undoubtedly the cheapest option for quad core thus far, so it has its place. Granted most enthusiasts would prefer C2Q at this stage but not everyone can afford $270 for a Q6600. Plus there are always the AMD fans... (hey Viditor, hows that Phenom build coming along ;) ).

That's not an excuse.

On that note, show me another Intel or AMD CPU with a bug that requires a BIOS workaround with a 10%+ performance hit...

If I remember correctly, there was a bug with Photoshop (forget what version) years ago that only happened when using a PIII 1.13GHz Tualatin? It occured in Photoshop in only one operation, and that was "Rotate" with a certain degree (45 or 90). That was due to the CPU errata and confirmed by Intel. So nobody is perfect.

Huh? The 1.13GHz Tualatins failed on plenty of stuff. I remember Tom's Hardware couldn't get through a linux kernel compile - both Tom's and HardOCP had multiple issues with those chips. I can't seem to find the original articles any more though :(.

what does this have to do with anything? I am not saying AMD is evil or something.
The P3 had such a bug? then you shouldn't have bought it. I wouldn't know because at THAT time frame I told everyone I know "there is absolutely no reason to buy an intel CPU aside of ignorance, AMD is better at every possible aspect"
But now the opposite has become true.

Anyways... "one in a million chance". One in a million what? I thought 3ghz means 3 billion operations a second does it not? :)
Or are you saying one in a million people will ever see it? How about after a whole year of usage?

Oh and speaking of visualization. I have gotten the chance to run a few virtual machines here and there.
