Its a fail if this is true.

How can you make a new CPU slower then the previous one. Don`t they test what they release? Hopefully something is seriously wrong.

Something is wrong. This is a preview (speculation). No real need to continue the thread any further.

They tried to make a good cpu. They failed. It is ok. Never hype anything so much.
Those CPUs will still be good for a budget PC. But for high perfomance fortunately or unfortunately Intel is the only way.
At least AMD give us good GPUs.

If 8 core 8120 Bulldozer>Intel 2500k= Buy
If 8 core 8120 Bulldozer

That is my thinking at the moment. The price is $205 so it directly competes with Intel 2500k. If it can not beat it or performs worse than there is no reason to buy it. People are comparing Bulldozer against the 2600k when the price is competing against the 2500k.

Actually it's a Romanian site's poor choice of words.

It's a real review. Look also at their comments at the bottom after they posted it:

we put AMD FX-8150 head to head with 2600K in 8 benchmarks and 3 games

It does look like they were able to get BD up to 5Ghz though on 1.476V:

Let me paraphrase another portion of their review comments at the end.

Original English translation:
Quote:
But with our short passing test suite, we had the most brutal awakening since test components and write reviews, pure and simple, it is difficult to find a scenario where the bulldozer is a competitive solution. Handbrake only approach the performance of i7 2600K and with lower price may be considered a smart choice, assuming you only x264 encoding, but what about heat dissipation and energy consumption, of the approximately 250 RON save will have to buy a cooler better and we will remain current for many bills. Or what of the lack of vigor in multithreaded applications less, or downright tragic performance in floating point calculations? How justified that in some benchmarks is considerably slower than its predecessor, the Phenom II? How explain that encourages overclocking AMD producer, but Bulldozer double their energy consumption and so much just by raising the frequency and voltage in modest limits?

Paraphrase:
But with our small suite of tests, we had the most brutal awakening since we started testing components and writing reviews.

It is difficult to find a scenario where Bulldozer is a competitive solution.

Handbrake approaches the performance of a 2600k, and may be a smart choice, if all you do is x264 encoding. But then what about heat and power?

What about the poor performance in multi-threaded apps?

Or the down right tragic performance in floating point calculations?

In some benchmarks, Bulldozer is even slower than its predecessor, the Phenom II!

Why does AMD encourage overclocking, when it greatly increases the energy consumption with just a modest overclock?

Ouchy! That sucks maybe they will get it right next time

If true its a even more failure then Phenom 1 was when it came out.

This does not fair well with me

I've been waiting for a while to build my new system.

im pretty sure chew* will be one of the first to post real benchmarks the second bulldozer is off nda

Knowing all this tells you one thing for sure, you can make it look worse or make it look better all depending on your knowledge of the chip and or your intentions.

As far as PI it's an antiquated bench and has not been AMD's strong point for quite some time.

Granted some results shown tend to lead to the fact that 1m times are bad but looking at the bigger picture we also know that in many cases you can validate 1000mhz higher in many cases with BD, which would point to the fact that you can run 1m at alot faster speeds than current AMD tech.

Things that make you go hmm like what kind of times will we see at 8 gig or even comparing BD to deneb/thuban when same cooling is used.



comming from one of the guy who was actually with amd to break the cpuz wr and test those chips behind closed doors ...
