AMD FX (Bulldozer / PILEDRIVER!) Owners Club! - Page 413

on load i am at 1.29vcore and i idle at 1.176


and yes i have plans to ditch out the stock hsf this summer


going h20

That tears it then. I bought a dud. Crap!

I had hoped Microsoft would come out with a patch or update that would give us 8120/50 owners the 10-20% boost we need
to keep up with Intel. Nope. Then Win 8 was said to have Bulldozer support built in. Nope. I have to say it, AMD are a bunch
of dumb bastards.

It's no wonder a whole lot on AMD exec's quit just before they released these dung piles. They knew.

Add me to the list as well. Current rig ___

Great.. Yet another one.

lol

I've held out on BD thus far, and will continue doing so until PD performance is confirmed. That will be my deciding factor on what my next build will have it it.. I really still wanna get a 8120/8150 to mess around with tho. Still a decent CPU regardless.

the FX is a dud???? only for the clueless..

for a true 8-core to flex its muscle, you need (surprize!!!) multi-threaded apps!
heres a compilation and feel free to add to it. :wink:

intel cpu performance and pricing is enabled by rigged benchmarks that lack disclaimers about optimizations for intel's uarch through software memory footprint, compiler settings/build(using ICC), and biased "reviewers" such as toms & anandtech;


amd offers ZERO dev-support and does not pay for play when it comes to software optimization for bentmarks.
in contrast to int-el: http://youtu.be/-M1eX5Vvrg8

see more intel-sponsored software optimization:

amd wont pay for software optimization, as intel does:
http://www.sdtimes.com/AMD_HELPS_OPENCL_GAIN_GROUND_IN_HPC_SPACE/By_Alex_Handy/About_AMD_and_HPC_and_NVIDIA_and_OPENCL/35956
"AMD won't be offering paid-for consulting services to help optimize applications, as Intel does."

amd tried working w/ bentmark devs, but quit BapCo due to unfair intel bias in points-scoring:

intel compiler uses suboptimal code paths resulting in poor performance on non-intel cpu:

even to this day, after antitrust settlement, intel compiler still will use suboptimal code-path if cpuid!=genuineintel

Cinebench 11.5 has cpuid check, likely uses sub-optimal code path for amd:

software optimization goes beyond using a biased compiler, it also involves memory management, cache strategy, algorithms, data structures, etc...

even athlon is better than core i7-nehalem in integer toom multiplication:
http://en.wikipedia.org/wiki/Toom–Cook_multiplication
http://gmplib.org/devel/
"FFT takes over for larger operands for machines with faster hardware multiplication. AMD's processors have great hardware multiplication, Intel's Nehalem's multiplication has twice Athlon's latency, and the venerable Pentium 4 has really poor hardware multiplication."


what is a fair benchmark? when can a comparison of CPU performance be considered fair?
"My personal opinion is that the best results obtainable for a given application on a given architecture is the best comparison between them."

IPC is not everything, Amdahl's law favors CPU with just the right IPC(not too much, not too little) but with higher clocks;

intel sandy bridge chipset bug results in lost data: http://techreport.com/discussions.x/20326

intel cpu uarch has worse decoder design than amd: "The decoding of instruction lengths has been a problem in Intel processors for many years. They tried to fix the problem with the trace cache in the Pentium 4, which turned out to be a dead end street, and now the apparently more successful micro-op cache in the Sandy Bridge. AMD have solved the problem of detecting instruction lengths in their processors by marking instruction boundaries in the code cache. Intel did the same in the Pentium MMX back in 1996, and it is a mystery to me why they are not using this solution today. There would hardly be a need for the micro-op cache if they had instruction boundaries marked in the code cache."

amd llano has better power management/better battery life than sandy bridge:
http://www.tomshardware.com/reviews/a8-3500m-llano-apu,2959-22.html

amd llano has better thermal dissipation than SB:
The key take away is that Llano’s power management is significantly more advanced than previously indicated and includes a few novel features, such as taking advantage of indirect thermal dissipation.
http://realworldtech.com/page.cfm?ArticleID=RWT083111130632
"One novel trick is that Llano’s algorithms recognize that idle blocks in the system will act as indirect thermal conduits for active components. Heat will flow from hotter (active) to cooler (idle) regions in the chip and the idle region will still dissipate heat into the heat sink, effectively creating a greater surface area for cooling. The credit-based power management and especially the indirect thermal dissipation are substantially more advanced than we had described in our earlier article on Llano and it is important to acknowledge this oversight."

Hello everyone. Sorry if I'm not supposed to post on a club page with out joining. I'm new to the forums, and looking for some info on ocing my fx6100 safely, and this seemed like a good place. Any tips or link to a good guide on the subject would be great. Feel free to pm me details.

*************Deal Alert************

Microcenter has the AMD FX 8120 BE for $149.

I know we all don't have a MC close to us, but great deal anyway.

are you underclocking right now?
My 6100 stock settings right now(house I'm at visiting is kept to warm for my oc even on water) sits between 3.6 and 3.9Ghz on the cores and 1.34-1.41 vcore.
I never see 3.3Ghz but will see 1.4Ghz from time to time
man cant wait to run my 24/7 oc again.
