AMD Bulldozer News and Discussion

[Extreme Gamer]

BD isnt a fail. It does what they made it for and it costs much less.

@Sukesh: The windows 7 patch WILL come out next year.

^^BD costs less because it didn't performed up to the mark and look at its power consumption.so BD is still a baby in that technology it needs to mature so it need some time and we hope AMD have that time in their hands.

Yeah Anandtech review makes things pretty clear... Although I have to say... that they conclude with this is not right... and we need to do a more detailed review again.

Nonetheless 8/16 bulldozer doesnt gain much(or at all) vs its 12 core older brother...

3 Questions @ AMD -

1. Why is Phenom II not coming in 32 nm?? It performs nearly as good in multi core vs BD and IPC is soooo much better, K10.6 has even up the ante with 6% higher IPC vs K10.5!!!!

2. Why is Trinity coming with PD cores?? Its IPC will only drop with PD cores and multi core performance of PD is not going to be good if you see K10.6 vs FX4100 benchmarks.. you can see where 4100 stands....!!!AMD FX-4100 Quad Core 3.6GHz Bulldozer Processor Review - The AMD FX-4100 CPU - Legit Reviews

3. When is 3870K is coming out??? (6% higher IPC than deneb & hoping that it will reach ~4.6Ghz on air... seems pretty decent.. for ~7k INR)

considering the 8150 now retails for 14k and 2600k at 18k... BD is now vfm.. almost touching 2600's performance in a few benchmarks and beating it in highly threaded ones.. good buy..

down point is still TDP.. so you need a good motherboard and psu in addition to a cooler..

considering the 8150 now retails for 14k and 2600k at 18k...

2600k - 18K Where in he*l u got that price??? I still get a quote of 16.5K(inc. VAT) for 2600K.

 

[Piyush]

meh....different sites...different reviews
I would not bother looking at BD benchmarks knowing that current OSs are not able to work out with BD processors
2013 is the year I'm looking for

zis thread has been bulldozed.

Clarification from AMD. The Desktop 6-core Bulldozer transistor count was 1.2 billion, not 2 billion. PR debacle. And I'm happy that they sacked almost all of their PR.

AnandTech - AMD Revises Bulldozer Transistor Count: 1.2B, not 2B

This thread remains locked though.

One more thing:

AMD Bulldozer A Surprisingly Sell-Out Sales Success. Victims: Phenom II & Athlon II | techPowerUp
According to this P2 and A2 are discontinued and will be available till stocks last.

Thread is cleaned up and back now.

AMD 'Bulldozer' gets an Update from Microsoft. | techPowerUp

Today Windows updater may have brought "Bulldozer" users a little surprise. A hotfix that increases the AMD flagship processors performance. As this "hotfix" is bleeding edge news any benchmarks have yet to be seen but this confirms Windows 7 was in fact hampering “Bulldozer” from performing at 100% in all prior benches. What percentage it was previously performing at has yet to be determined. Here is a small snippet from the Hotfix release notes.

This article introduces an update that optimizes the performance of AMD Bulldozer CPUs that are used by Windows 7-based or Windows Server 2008 R2-based computers. Currently, the performance of AMD Bulldozer CPUs is slower than expected. This behavior occurs because the threading logic in Windows 7 and in Windows Server 2008 R2 is not optimized to use the Simultaneous Multithreading (SMT) scheduling feature. This feature was introduced in the Bulldozer family of AMD CPUs.

Hopefully, the benchmarks will reflect something positive. Fingers crossed.

I'm wondering whether it will improve anything. Expect it to be a tid bit improvement here and there. Plus, further patches being released.

 

[Skud]

I think if the top 3 have enough improvement to separate them from 1100XT, that will do. But whether such magic is at all possible, is a big question.

Plus the patch is not available publicly atm. Looks like work in progress...

 

[ico]

Some results: The 1st windows 7 scheduler patch results are IN. Have fun!

Improvement is only being seen in games.

 

[Skud]

That would be even better, from a gamer's perspective.

 

[Jaskanwar Singh]

seems promising. waiting for reviews.

 

[vaibhav23]

BD will remain in news for some more months as they still have B3 stepping and Windows 8 launch

 

[sukesh1090]

Waiting for benchmarks.

 

[Extreme Gamer]

Benchmarks are out :shrug:

Check ico's link.

 

[sukesh1090]

Nah.They are just 2 games and cinebench and that too not tested in correct methodology.but still gives some idea.thanks ico.

 

[Skud]

I guess the FX6200 benchmarks would be interesting after this patch. Hopefully, they have done something to the power consumption to the very least.
