AMD puts quad core chips with only three operational cores to some use.  (Source: Advanced Micro Devices)
AMD's triple-core CPUs bridge the quad-core gap at dual-core prices

The industry and its consumers knew they were coming and who they were coming from but the "when" part was the biggest question until today. AMD has officially launched the Phenom X3 8000 series desktop processors today with two models in the series.

The Phenom X3 processors are the first desktop processors to feature a 3-core design and are aimed at bridging the price gap between dual-core and quad-core products. The Phenom X3 is basically a quad-core package with one core turned off.

AMD's Phenom X3 series will launch with two models, the 8400 and 8600 which will feature clock speeds of 2.1 GHz and 2.3 GHz respectively. Each model is said to consume 95W, feature 512KB of L2 cache per core and 2.0MB of L3 cache, the same amount as the Phenom X4 processors. The Phenom X3 series will also feature a maximum HyperTransport speed of 3.6GHz.

The initial launch of these Toliman triple-core processors will be aimed at OEMs and system builders so there is no word on single unit pricing.  However, previous roadmaps indicate Phenom X3 pricing will reach the sub-$100 price point.  HP and Dell began selling triple-core systems last month, though AMD's announcement indicates channel availability is on the way.

The tri-core processors are the last of AMD's "B2" stepping, and are still technically affected by the TLB bug.  However, since Phenom X3 is targeted for low-end systems rather than virtualized server environments, end users do not need to worry about instability.

"B3" revisions of the Phenom X3 processors will likely come later this year, as the rest of the AMD Phenom roadmap transitions to B3 next month.

The next batch of Phenom X3's will include the 8450, 8650, and 8750 at 2.1GHz, 2.3GHz, and the new high point of 2.4GHz respectively running at 95W, and should be expected sometime in Q2 2008.

Don't call it a comeback! Really. Don't. It's not.

I've been a huge AMD CPU supporter for years, from owning a 5x86/133, Athlon 1.33 Ghz, and now a Sempron 3100+. Not counting the hundreds I've sold, or worked on, in the past.

There really is no real compelling reason to buy any of their consumer CPUs at this point. The top of the line Phenom is competitive... With the lowest end Intel Quad Core offering. (Q6600)

Possibly the tri-core can do well, I just don't see it at the current clock speeds unless it comes out at some ridiculously low price point. (<$100)

It seems AMD is going through their "Netburst" stage that Intel experienced just a few years back versus the Athlon64.

AMD's competition has made Intel put out some great CPUs, I'm hoping they stick around and start to innovate again.

Have you seen the price of the higher end intel CPUs that have no competition? How about $1000 for a 3GHz quad core CPU that runs a little bit faster than the 2.4GHz one? Is it 4 times faster? It should be, because it costs 4 times as much. Way out of control. AMD is a very important company, if for nothing more than to make sure intel doesn't have their way with the world.

That's because it's an enthusiasts CPU, which is why its the Core 2 Extreme. Let's not forget Intel had regular models below that too.

And don't make it sound like AMD isn't guilty of charging a premium for enthusiasts either, need we mention the Athlon 64 FX?

I made that point already in my post... (As I quote myself)

Intel has $1000 cpus. Agreed. AMD had similarly priced CPUs. (FX-51, FX-53, FX-55, FX-57, FX-60, etc) If you have the performance, you can sell the niche part. AMD doesn't have it now, and thus doesn't even attempt to compete. Current indicators show that they won't be able to compete on the "high" end for awhile, and the issue I brought up is AMD's current "high" end only compares with "low" end Intel parts.

Um... Most computers have one core. That's an odd number. Three is an odd number. Neither is symmetrical...

Having an odd number of cores is not going to be a problem. People forget that there is more than one way that multicore can be used

a) by the operating system to handle multiple processes and threads
b) by multiprocessor aware programs
c) by both the OS and the application.

One core doesn't run in MP mode, so that's a moot point and you know it ;). The OP is correct when he says that some applications require even cores. I received a tech bulliten for some software that I use that will not work with the AMD tri-cores. I'll also admit, this is not mainstream software and there are other odd ball packages that may have problems. For most consumer applications though, you'll be fine.

He was just advising caution with the 3 cores, that's all.

I look at the tri-core release this way:

If they can offer these chips at a low price point, you can get alot of value from something like this. If you paired a tri-core phenom up with a cheap 780g motherboard, you get all the great HD decoding/playback advantages and performance at a low price. Those two products together make for a nice media platform. Granted, the Core2 setup is going to smoke a PC like this in media encoding. But if you don't bother doing that, it's not a huge issue. Besides, most applications aren't multithreaded past 2 cores yet. So you're still getting enough umph to do a majority of the processes someone would be using this setup for.

The only thing I don't like about this is that it's still using the B2 stepping.

I've been an AMD customer since the K6-2 line, so maybe it's just a personal bias I feel this way. I'm not trying to be a fanboy, but if I could price a core system (RAM,CPU,Mobo,GPU,sound) together for around the $250-$300 price point, that's a sweet deal.

But the real value will be determined when the tri-core is benchmarked against the quad-core phenom. Until then, I'm just talking out of my posterior.

You made valid points, but I have to mention something else.

If the Tri-Core is priced similar to multiple dual-cores on the market, people will automatically jump for it. Take an average-joe shopping for a mid-range system around $600. He goes to <insert B&M store> and looks at 6 prebuilt systems:

1 Quad core ($1,000)
2 Core2duo ($700)
2 X2 ($500)
1 Tricore ($700)

AMD will most likely win the sell regardless. The run-of-the-mill buyer is not going to know more than what the salesman tells them, and what the price says. If they see a tri-core priced similar to a dual core then they will go for that computer.

Just my thought.

The average consumer is slow to go against Intel to begin with, so even similarly priced AMD is not going to push as many systems as Intel. Sure some will fall for the 3 is better than 2 idea, but most will see that Intel Inside sticker and go to it.

"There really is no real compelling reason to buy any of their consumer CPUs at this point."

Except for the most popular reason of all, which is PRICE.
Remember, not everyone buys $2000 systems.. the vast majority of sales are at the low-end of the market. With the AMD pricing figures I read, the tri-cores are going to be VERY competitively priced with Intel's dual cores with similar clock speeds.

I think the X3s will offer a tremendous value for consumers who buy PCs are big box stores and for OEMs to offer a new "in-between" value product.

Low end buyers ain't gonna buy quad cores anytime soon, either from AMD or Intel.

In the quad core arena you only save around $40 if you buy a 2.5ghz phenom or a faster, much better overclocker Q6600 2.4ghz.

Intel is way ahead of AMD this time around, coupled with the vast number of farms they have to produce the chips, achieving economies of scale. AMD was too busy acquiring other companies and attempting to mix GPU and CPU processing together, which imho is a great idea. They probably ran into difficulties trying to make that work.

It is, however personally, I feel their efforts would have been better served pushing motherboards and motherboard chipset development. Every system needs a motherboard, not every system needs a video card.

Also, the lack of a solid in-house chipset has been the bane of the Opteron's existence. AMD had such an opportunity to score big in the server arena, but did not have the chipsets or stable motherboards available to fully compete with the, up until recently, much lower performing Xeon. Hypertransport was never utilized to its fullest on the server boards, and now with Intel coming out with their own version, the window of opportunity is closing.
