AMD - Bulldozer Chitchat

[CAT-THE-FIFTH]

There has always been a 95W 8120.

It actually took until December for any of them to be available it seems.

Still,as usual AMD marketing failed. They should have put out some of the 95W FX8120 models for review at launch,considering how poor initial FX8100 series availability was.

So the big news is just that there is a 95w 8140... ?

Have you noticed the other CPUs have a 10% clockspeed with no increase in TDP?? Also,the 95W FX8120 is very rare and a few turned up in December. If anything, since the roadmap is indicating 95W CPUs being the norm,then yields on the lower voltage parts are increasing.

IMO, yes.

I'm with Biscuit on this though: the TDP is too high for the lesser models. The 8120 could definitely be had before December, in fact, its the only 8120 I've seen stocked from the etailers i browse.

All were 125W TDP models. The few people who got the 95W ones were in China and these were OEM CPUs sold in the shops. Even then it was very hard to get hold off. It took over two months to appear,ie,December.

The fact that 95W models seem to be actually appearing as default indicates,things are improving. Also,as you know AMD tends to favour speed bumps at the same TDP rather than TDP drops. In fact nearly a 10% improvement in the lower end models is actually quite big by AMD standards. Usually it is only 100MHZ bumps every quarter or two. These are 200MHZ to 300MHZ bumps.

Clockspeed bumps with the same model number is bad practice imo. It seem like there is absolutely no rules to follow for naming CPUs or GPUs anymore.

AMD don't seem to band their TDPs that closely though do they. Looking back at Phenom (& II) the next common rating down is 65W. There were a bunch of dual core Phenom IIs at 80W for some reason, which probably means someone like HP asked for them.

I assume that is because OEM designers build a chassis for 95W, and if the chip actually pushes out 70W they don't care.

The 8140 is new, slightly lower clocks but 95w TDP and the 8120 is a re-release with the same clocks but also with the lower TDP. Shame there is no sign of a 8170 at the same or slightly higher TDP with a bump in clockspeed.

I would have hoped the lower end chips would be down to 80-70W TDP if im honest.

Overall it looks like a positive step for AMD, are these still being made in GF or have they shifted to TSMC?

It's the same for most CPU/GPU MFRs really, for example look at the 2500 vs 2600 - the 2500 uses quite a bit less power (something like 15w difference) under full load and yet they both have a 95w TDP.

Remember it's only the 'thermal design power' not the max or average rated power which can be a fair bit higher/lower. The TDP is to help system builders/thermal solution MFRs to accommodate a rough heat output under normal load conditions.

This is very interesting:

It should hopefully mean Trinity should have better power consumption characteristics over Llano. It could also explain why the Trinity die seems to have a large uncore area too.

Edit!!

Supposedly the die area is not affected by having to implement the technology after reading the article.

Very interesting. So, if you want to overclock, you need to re-tune your mesh inductors to match the new base clock? This could make black edition cpus much more attractive (or in other words, non BE cpus might be naturally locked unless you can hit a harmonic).

Hopefully this is true:

Nope. Anyway,it is not relevant to the thread.
