The Bulldozer Review: AMD FX-8150 Tested
by Anand Lal Shimpi on October 12, 2011 1:27 AM ESTOverclocking
AMD indicated the FX-8150 was good for around 4.6GHz using air cooling, 5GHz using water cooling and beyond with more aggressive cooling methods. In our experience with the platform, hitting 4.6GHz, stable, on a stock AMD HSF was not an issue. Moving beyond 4.6GHz on air saw a significant decrease in stability however. I could boot and run benchmarks at 4.7GHz but I'd almost always encounter a crash. I couldn't hit 5GHz on air.

Ouch.... Not looking good. :SThanks for the reply, again great review!!

Ignoring the power consumption it seems to me that @4.6GHz it should start being quite competitive.So can we expect base clocks to rise once significant volume of these chips starts getting out and GloFo refines the process?
I also must admit I didn't expect 2 bn transistors. All the time AMD was bragging about how much they saved and then we get this behemoth. No wonder they have process issues. Such big chips always do.

Well it is an 8-core, not a 4 core. 2x 995M (Sandybridge 4C) almost 2B, though I am sure the multply isn't exactly correct. A lot of it depens on the L3/L2 RAM amounts. The savings seem to be minimal.I am still confused about why they so deliberately chose to go with a relatively low single thread performance. My main application is multithreaded, but since it's such a mixed bag overall I am pretty unsure if this will be my next CPU, unless I get to see convincing Cubase 6 benchies. For an FX moniker it needs to perform better than this anyway.
I'll throw in a lyric from The Fixx
"It doesn't mean much now, it's built for the future."

Wow, no wonder they say you need water cooling or better to go 5Ghz+.enterco - Wednesday, October 12, 2011 - link
AMD should send a developer team to CryTek to help them release a patch able to use more cores :)medi01 - Wednesday, October 12, 2011 - link
Uhm, what about other numbers?IlllI - Wednesday, October 12, 2011 - link
this might be the final nail in the coffin. We might have to wait longer for it to be competitive? People have literally been waiting for -years- for amd to catch up.probably by the time piledriver(or whatever it'll be called) comes out, ib will be out (and even further behind intel)
btw I think tomshardware tested it with windows 8 and it was still a turd.
I seriously hope you can get some answers/reasons why amd released such a woeful product. Maybe this was why dirk was fired? All I know is after 7+ years of amd, my next processor will be intel

Desktop CPU's are Halo parts and as such are irrelevant. It's the Server and OEM Laptop CPU's were AMD needs to perform and AMD's server share just keeps dropping.lyeoh - Wednesday, October 12, 2011 - link
Thing is I wouldn't want to use them in my servers: http://us.generation-nt.com/answer/patch-x86-amd-c...FWIW when the Athlon64s first came out, we bought a bunch of them, they were not bad, but there were clock issues - the TSCs weren't synchronized. So had to set idle=poll (and thus using more watts).
You can blame the OS developers, but most people buy new hardware to run existing operating systems and programs on, not future unreleased ones.
It sure is looking bad for them. I won't be buying AMD CPUs but I hope the fanboys keep them alive ;).

"Other than the 8150, only the quad-core FX processors are able to exceed the 3.3GHz clock speed of the Phenom II X6 1100T."The 6 core FX is also clocked higher?
