Calling all you long time members, veteran posters...

post #1 of 26
Thread Starter 
.. I would like to hear a collective view on what's going on with Bulldozer at the moment. The likes of xd, ENTERPRISE, el gappo, amongst many other old-skool OCN folks if I could be so privileged as to ask what your thoughts are on the release?

I would like to expose an unbiased view if possible.

Since my first post at OCN in September 2010, as a first time pc builder newb, I feel I have dissipated some of the best advice possible on the web and have been navigated through choosing some of the best components for price/performance possible at the time and for that I would like to say thank you so much.

Especially with AMD. My £40 mobo unlocked my x2 55 to an x4 B55 and has been running super fast for the cheapest price possible, I couldn't afford it any other way.

So now, I have spread my wings and have pulled the trigger on a GA 990FX UD3, which is running brilliantly with my x4 B55 - I am really happy. I will hopefully be purchasing a FX X4 very soon and no doubt will be chuffed with the experience...

...but all of these BD reviews are a bit daunting don't you think?

This is the first time i've been following a launch of this calibre. Is it always like this? Them BD cpu's are still so bloody cheap I can't resist. My 'old/spare' parts are going in my first ever HTPC. Wish me luck.

So yeah, just because there is a lot dross opinion going atm I just want some of you 'old timers' to give some of your realistic views on whats going on, ideas on performance, thoughts on reviews.

Cheers, thanks in advance.

Let REAL people get the setups going and then decide or make an opinion, with all the trade for trade out there I trust no synthetic benchmarks posted on ANY website. I want to see real set ups ran by real PC enthusiasts not some blow hard that lucked into a web site running bench marks.

I think the people who got so upset are the ones that truly want to be "first on the block" benching, video un boxing etc. I have not bought a piece of hardware EVER hours or days after release, I watch the other guinea pigs

Sit back they will come

I've found this to be a very objective approach in analysis of Bulldozer. Very informative.

The general response from my connections is that "something is very wrong". ASUS is scrambling - why would they bother? Better question is why would AMD bother releasing? I'm still waiting - that cost me nothing.

If I were you, I would either get a 2600k, wait for ivybridge, or save a little money and get a thuban. Core for core, thuban is faster, and much much more power efficient.

What do you mean Asus is "scrambling"? I smell something going on here....

Well I am by no means an extensive expert of computer hardware. I pretty much only learn what I need to know to make a good decision for my computer needs based upon my budget limits.

And what I can say without a doubt from what I've seen so far is that I would never consider Bulldozer at this point.

It has EXTREMELY low IPC performance. Meaning poor performance in a wide variety of programs, especially ones that only use a single core. Or programs that are not optimized to take full advantage of Bulldozer architecture.

Gaming is the most important factor for me in my computer needs and Bulldozer is SERIOUSLY lacking. Although I do some video encoding, audio recording and editing, and streaming games online (which should benefit from 8 cores), at this time it appears that Bulldozer is still falling behind Intel 2500k and 2600k in many of these categories.

Overall Bulldozer has absolutely no redeeming qualities for a user such as myself. The benchmarks it excels in seem to be random, unpredictable, and stuff that really isn't that important to me to begin with.

My recommendation would be for any new consumers to either buy the 2500k or to wait for Ivy Bridge. I don't see the next generation Bulldozer's competing with Intel at this rate.

I remember the AMD, Cyrix, Intel struggles, the Pentium II lanuch, the Athlon Classic launch, the PII recall, the Pentium IV debacle, the P4C Northwood revival, the Athlon 64, the first dual-cores, the return of P6 in the Pentium M, the Core 2 launch, the Phenom Disappointment, the Core i7 revolution, the Phenom II revival, Sandy's Bridginess, and now Bulldozer.

In every case, mass fanboy denial and suicides as one team or the other doesn't live up to what are usually completely unrealistic expectations, or exceeds overly low ones.

Yes, it's always the same.

"How could you do this to me?!!!! I've spent at least 130 dollars on your products in the last 10 years, I've got to be your biggest customer! I LOVED YOU! WHY U BETRAY ME?!" *click...bang*

"I don't believe any of these five hundred reviews that all say it sucks. No processor with that many pins and a heatspreader so shiny could be this slow. It's a conspiracy I tell you, and it will be revealed."

While not a long time poster, I just spent the last 3 hours reading everything that is "officially" available. Here is the short of it.

BD single threaded performance is currently even or worse than thuban and significantly worse than 2500/2600k.

BD heavily threaded performance in most cases is significantly better than thuban and even or beating 2500k. In a few cases BD multi threaded beats 2600k.

turbo core is now a great feature that adds ~5% performance to most tasks (single and multi-threaded)

Power is much lower than PII and slightly over 2500/2600k at idle. As soon as all cores are stressed or a couple cores are turbo'd power is at max TDP. Overall consumption in an active system is higher than PII and 2500/2600k.

OCs reliably to 4.6k on air, and around 5k on water. Power consumption increases drastically with OC.

Overall, if you are a gamer, 2500k is a clear winner. If you are doing heavily threaded stuff, 8150 is generally weaker than 2600k, probably better performance per dollar than 2600k, and for sure better performance and value than 2500k. You should still double check for your specific workload b/c some results defy the general concepts. For the typical user, it seems like 2500k is the best value on the market.

There is some controversy in the results since nearly all reviews were based on the AMD provided CrossHair V motherboard. There are a couple of outliers that did not use CHV and had some contradictory numbers. However, even in these numbers, the general trends hold true. Basically it's a matter of how much worse is single threaded and how much better is multi-threaded in relation to the 2500k. (ie. a couple reviews place BD closer to 2500 single threaded and closer to 2600 multi threaded)

On top of that is alot of information on projections of why single thread performance may be poor. There is definitely a bias that the Windows 7's task scheduler does intelligent scheduling for Intel cores and is not aware of AMD's module architecture. Comparing some results to the Developer Preview of Windows 8 (which is aware of AMD modules and does intelligent scheduling), performance on AMD goes up by 5-10% while intel remains effectively the same. It appears that the new branch prediction engine in BD could use some fine tuning which could give a boost to single and multi threaded apps. Finally, cache latency is long.
