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.

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.
