AMD Athlon 64 X2 4800+ 65-nm Brisbane

AMD's released a flurry of new CPUs in the past few weeks. Up for eval today is the X2 4800+. This CPU is based on AMD's new 65-nm Brisbane core and runs at 2.5GHz. With the smaller manufacturing process, the X2 4800+ should deliver better thermals and power, but does it? Yes! In fact, you may be surprised by how much. What about overclocking? You'll have to read today's article to find out!

What you will get from today’s 65-nm AMD CPUs though is better thermals. This is because the new 65-nm CPUs boast lower power consumption figures. AMD lists a peak power rating of 65W across the board for all their 65-nm CPUs. In comparison, AMD’s 90-nm CPUs ran at 89W max, with energy efficient models at 65W and 35W.

With the smaller process, die size is also reduced, down from 183mm2 to 126mm2 on AMD’s 65-nm processors. The new 65-nm CPU’s are built on AMD’s “Brisbane” core and all announced models to date ship with 512K L2 cache per processing core (1MB total L2 cache). Model numbers announced to date include the 5000+, 4800+, 4400+, and 4000+. The following chart summarizes AMD’s current CPU lineup as it stands today, for simplicity I'm just listing X2 and FX CPUs

A quick look at AMD's 65nm Athlon 64 X2 processors :-

AMD HAS BEEN PROMISING for some time to deliver chips made on its 65nm fabrication process by the end of 2006. The year's end is perilously close, but a small package arrived at Damage Labs last week bearing evidence of AMD's success: a pair of 65nm Athlon 64 X2 processors. Looks like they've just made it in under the wire. In fact, Athlon 64 X2 processors built in this 65nm process are filtering out into the market now.

Process shrinks often bring with them some nice benefits, because smaller chips tend to require less voltage, consume less power, and generate less heat. They also sometimes allow more headroom for clock frequency increases. The question is: how is AMD doing on these fronts? What benefits does its 65nm process bring to the Athlon 64 X2? Let's have a look.

disappointives new cpu

and some L2 speed problem

When there's a new smaller die created, there will be some problems. Hopefully they will fix these in the later revisions.

 

Ya, they should just invest more times in the Die Shrink matter so that can't create ne problem after release.

 

Impossible, most the time it's not a bug in the die shrink, rather a bug in the development process and logic verification above all. You'll need working time with any new process to figure out it's nuances and kinks, it's just common sense.

more articles. i'm not getting any X2 higher than the 3600+

 

hehe. i'm not OK with paying RM 600+++ for a processor.

wonders what would be the price of E4300. that one looks interesting.

if not, i'll just get myself X2 3600+ but fact is, i'll be ignoring dual-core processors for a while.

 

indeed. it's the only thing that makes me think of getting dual-core.

E6600 price is ridiculous. (and so are X2 5200+ and whatever that's above RM 500 in my eyes that is........haha)

btw Chai, you say you can't live without one.......but you are living without one, right? or do you have? you can get E6300 OC to 3ghz also mah.

the only dual-core unit i have now is my Macbook.

 

I want to buy these Pentium Ds if they are less than RM280. Eventhough it's an old technology, but the most basic ones are these. I'll see the Celerons and the Semprons in Dual-Core - sure will beat up the highest-end single cores.

 

Intel will cut prices in Q2...
At the moment E4300 is selling for about S$290 here, I just picked one up yesterday.

 

I won't be busting up my wallet with processors above RM400 - just keep it fine and low enough if you are a casual user. The benchmarks can tell that the Cores are significantly better, but it's only a matter of a few more seconds and FPS different only.

The X2 3600+ is only 5% slower than the 3800+ if I'm not mistaken, this is one example.

 

WTH?!?! RM 620, i might as well get an E6300 with that $$$.
