World Exclusive T-bred review

Another picture of a non-square t'bred die does anyone know why? have they added more to the outer core of the die to increase contact area?
 
Mingon,

All Tbred pictures have a core that is rectangular, rather than the more square shaped Palomino core chips. from this pages core measurements from a week or so ago, "width" between the Palomino/Thoroughbred core was more or less the same, but the "height" is significantly different, which accoutns for why it looks wider.

It is still 80sq mm in contact surface, no change from earlier numbers.

Mikewarrior2 - so you think they have reduced the height to increase the contact area , seems like a lot of effort to change the amount of layers without including any changes. What effect would having a thinner but wider cpu have on cost? I take it must be cheaper
 

Another thing to take note is that Tbred does not have any performance advantage over Palomino at same PR ratingp

The 45A the other thread was talking about will be true for Tbred with 2000+ ratings.
 
Their are some suggestion floating around that the pipeline might have been lenghtened to give more headroom, this seems unlikely as it would reduce IPc wouldnt it?
 
The 45amp thing just cannot be true. Nobody would be able to run it stabily, unless you had an Enermax 550 or something. My 430 Enermax only gives out 42 amps on that rail.
 
45Amp just to pull up the 5v rail on the transistor??

Man, that thing is going to need at least a good watercooling system to survive!
 
Mingon,

No, i believe you misinterpreted my post.

Let's look at a CPU from top to bottom. Height would be the top of the die to bottom part of the die. Width will be left to right side. Depth will be the height of the core versus CPU PCB[/b].

Tbred die "width" is roughly the same as Palomino core width. Tbred die "height" is significantly smaller than a Palomino "height". Depth remains the same on both CPU's.

Tbred is not really wider than Palomino chips. It is much more a perception thing with the different shape of the CPU.

Reducing the "height" does not increase contact surface. It drastically decreases it.

Mingon-

Get over the die shape already dude, Durons are shaped the exact same way, just skinny up and down insted of left and right.
 
couldnt make sense of the pics
😕

All the preproduction reviews I have read have not accurately reported the performance of the production cpu. I do not read them anymore.
 
i'd like to know exact power consumption and heat dissipation figures too.

just a die shrink....no increased pipeline, as u can see from the figures...also, they should've ran an SSE2 intense benchmark to see if some other instruction enhancements were added, but i doubt it...i think that'll wait for Barton.

this really is just a die shrink to give the duron line a little room and reduce power requirements.

if u're waiting for anything remotely interesting, wait at least for barton...i suspect most people will want a clawhammer by then tho....ah, what can ya do?
 


<< wait at least for barton...i suspect most people will want a clawhammer by then tho >>

nah, barton will upgrade my current rig, and hammer will be a new rig, so i'll have both 😀
 
According to that site, here are the voltage and power consumption figures:

Athlon XP(Palomino)
1700+(1467MHz) - 1.75V - 64.0W
1800+(1533MHz) - 1.75V - 66.0W
1900+(1600MHz) - 1.75V - 68.0W
2000+(1667MHz) - 1.75V - 70.0W
2100+(1733MHz) - 1.75V - 72.0W

Thoroughbred
1700+(1467MHz) - 1.60V - 55.2W
1800+(1533MHz) - 1.60V - 56.9W
1900+(1600MHz) - 1.60V - 58.6W
2000+(1667MHz) - 1.60V - 60.3W
2100+(1733MHz) - 1.60V - 62.1W
 
T-breds are still going to be just as challenging to cool off as current XP's, if not more so. The reduction in wattage comes with a big reduction is surface area.

I predict that even retail heatsink will soon come with at least copper inserts to attempt to pull as much heat off the core as possible.
