Bulldozer junk?  

post #1 of 61

Thread Starter 
I was browsing through here and caught a post about the "bulldozer failure" and how ppl are jumping to Intel. Something about a bunch of problems that no1 expected. I was at work and it got busy so i couldn't really read the article. Can anyone elaborate? I'm in the market to get a new CPU/MB and don't want to waste money on this if they aren't any good.

As for actual problems, those were bios issues that have already been fixed by the motherboard manufacturers. It took a while, but they did it. What was happening was that improper coding interfered with proper running of Steam games, and several other games.

As for the failure. Bulldozer runs hotter and slower than Intel. Performance simply is not there. In single-threaded applications, it struggles to beat its predecessor, Phenom II. Multi-threaded is actually where it shines, but its power consumption is still much higher than Intel for the same performance.

But you're way behind the times, this has already been discussed numerous times in the past 4 months, just take the time to look it up a little. Specifically, just look at Bulldozer reviews at [H]OCP, Overclock.net, Anandtech, etc

It's a multithreaded CPU aimed at a singlethreaded market. There's also a lot of other mistakes from AMD that I hope they never do again.

As for this current generation of Bulldozer chips, there's no reason to buy one over a thuban.

It's not a terrible chip, it'd be an upgrade from your Kuma, but it just doesn't have the same single threaded performance of the Deneb or Thuban chips of last generation. Yes, it shines in really multi-threaded work, but there isn't very much out there for consumers that makes use of it. The one advantage it has is in overclocking, no restrictive Bclck fixes. I'd dearly love to wind up the clock on this Intel like I did on my Deneb chip, but I can't. If I want to do that with Intel, I have to buy the insanely expensive s2011... *sigh*

But would you be (don't take it personal) overclocking to improve performance, or just to reach a higher mark?

BD:

High power consumption,
requires better cooling for OCing than SB
can't really compete with intel's offerings, except in really specific workloads
loses to its predecessor Phenom II in some cases,
bottlenecks multi-GPU setups, and sometimes even high end single GPUs in gaming
relatively expensive for what you get.
...

There are just so many downsides to BD that it really is not worth it compared to intel's Sandy bridge, except if you're running some specific apps and can be sure that BD is better in those. But generally if that's the case you'll be running your rig at full load for long periods of time and you end up spending enough money for your power bill that you could just as well have bought an i7.

Power consumption goes through the roof when you over clock, Just do the right thing and buy a Sandy Bride based 2500k and be done with it smile.gif

Thats kinda the point I was getting at. Why overclock the BD to reach IPC levels of the intel competition, when you'll have to pay more for cooling and power bill and PSU, when you could've just bought the intel equivalent that reaches the same individual thread performance at lower clock and lower power?

Bulldozer is a long way behind the i5 2500k and above for gaming because it doesnt utalise it's cores as well as intel chips do. It also runs hotter and doesn't overclock as well. Although the top end BD has 8 cores, they are useless in gaming as most games only support 4 cores. The i5 2500k is actually cheaper than the 8 core 8150 and will perform MUCH better.

I went from a AMD 1090T 6 core to a i5 2500k and the different was amazing. I won't be going back to AMD.

All depends on what you intend to do with this CPU! rolleyes.gif
AMD offers better clock speeds, easy overclocking and cheaper prices than Intel. So if you are cost sensitive and still want decent performance then AMD.
