Review Consensus: AMD FX Processor 8150 Underwhelming
It's been in the works for over three years now. That's right, the first we heard of "Bulldozer" as a processor architecture under development was shortly after the launch of "Barcelona" K10 architecture. Granted, it wasn't possible to load close to 2 billion transistors on the silicon fab technology AMD had at the time, but AMD had a clear window over the last year to at least paper-launch the AMD FX. Delays and bad marketing may have cost AMD dearly in shaping up the product for the market.
After drawing a consensus from about 25 reviews (links in Today's Reviews on the front page), it emerges that:
After drawing a consensus from about 25 reviews (links in Today's Reviews on the front page), it emerges that:
- AMD FX-8150 is missing its performance expectations by a fair margin. Not to mention performance gains in its own presentation, these expectations were built up by how AMD was shaping the product to be a full-fledged enthusiast product with significant performance gains over the previous generation
- AMD ill-marketed the FX-8150. Hype is a double-edged sword, and should not be used if you're not confident your offering will live up to at least most of the hype. AMD marketed at least the top-tier FX-8000 series eight-core processors as the second coming of Athlon64 FX.
- FX-8150 launch isn't backed up by launch of other AMD FX processors. This could go on to become a blunder. The presence of other FX series processors such as the FX-8120, six-core and four-core FX processors could have at least made the price performance charts look better, given that all FX processors are unlocked, buyers could see the value in buying them to overclock. TweakTown took a closer look into this.
- There are no significant clock-for-clock improvements over even AMD's own previous generation. The FX-8150 drags its feet behind the Phenom II X6 1100T in single-threaded math benchmarks such as Super/HyperPi, the picture isn't any better with Cinebench single-threaded, either.
- Multi-threaded data streaming applications such as data compression (WINRAR, 7-ZIP) reveal the FX-8150 to catch up with competition from even the Core i7-2600K. This trend keeps up with popular video encoding benchmarks such as Handbrake and x264 HD.
- Load power draw is bad, by today's standards. It's not like AMD is lagging behind in silicon fabrication technologies, or the engineering potential that turned around AMD Radeon power consumption figures over generations.
- Price could be a major saving grace. In the end, AMD FX 8150 has an acceptable price-performance figure. At just $25 over the Core i5-2500K, the FX-8150 offers a good performance lead.
- Impressive overclocking potential. We weren't exactly in awe when AMD announced its Guinness Record-breaking overclocking feat, but reviewers across the board have noticed fairly good overclocking potential and performance scaling.

(Typical LordJummy knee jerk reaction)
Done some digging on Bulldozer and its possible issues related to today's software and Windows 7.
1) Memory Bandwidth is somehow getting hampered.
2) Cache Thrashing Issue
3) Scheduling Issue
4) 4 Cores = 2 Threads per Core vs. 8 Cores = 1 Thread per Core – Somehow the OS is getting this mixed up (Windows Update should resolve this issue so it can be utilized properly)
5) Possible a performance Bios update is needed for Socket AM3+ motherboards. Current Bios used for reviews should be null/void.
6) They should conduct a SLI/Crossfire Benchmark with Bulldozer and see what happens.
7) AMD what happend to Quad-Channel? Surely Bulldozer is not being feed enough food IMO.
Just my take in doing some research on the internet about Bulldozer. I still commend AMD for the innovation put into Bulldozer, and I too believe this thing is ahead of its time. Software developers need to quick mucking around and help utilize Bulldozer to the fullest just as they constantly do for Intel CPUs. W1zzard, as soon as you get that Bulldozer, please by all means Molest the bloody chip and give a wide range of scenarios if you can, in regards to 8GB of DDR3-1866 vs. 16GB of DDR3-1866 etc. I believe Bulldozer will do better with more DDR3 memory along with running a CrossfireX and/or SLI setup. Anyhow you know your stuff,
2. Possible fix with #4
3. # 4, but doubtful. May have to wait until Windows 8
4. I hope so.
5. Doubt it.
6. It's been done. Reviews are out there and it's not very impressive.
7. It's not there, it is what it is.
Apart from the performance that you say you expected to be like this, do you think the desktop CPU market needs these products? Do you think AMD made the right choice to put out a processor that performs on average 10% better than their previous lineup on multithreaded and on par or worse on single threeaded?
Do you think AMD has any chance to sell a chip that costs 60$ more than the i5-2500K while on average at stock clocks it performs better in 2-3 benches out of 10? Do you think anybody outside the small enthusiast community will wait for software optimizations in order to increase the potential performance of the Bulldozer?
Do you think that a guy who has an X6 should upgrade to the FX? Do you think that a guy who has a SB should switch to FX? Can you please tell me who will buy this chip?
SB to FX? Nah, unless you want to play with something new. Many will do this; erocker already has...
Who will buy the chip? Many people will. We have a situation where either AMD was incapable of making enough chips, clearly, if they cannot provide every review website with a retail sample, or there's something else afoot. Whether the problem is yeilds, or that all the chips are already sold to OEMs..doesn't matter. Considering that almost every retailer that did have chips yesterday is now sold out, I don't see why you would even question AMD's ability to sell.
The fact of the matter is, if you ignored every other site, and listened to just what I've been saying the past few months, none of this would have been any surprise.
90% of chips on the market are overkill for most people's real needs. None really needs to overclock. It's not like BD is incapable of running games or other apps because it's too slow...it's just not quite as fast as Intel, and is priced accordingly. Daily usage there would probably not be a lot of discernable difference in usage, for things like web browsing and such. I don't understand how it's disappointing, at all.
2.) people whom have a AM3 board and dont want to change boards
3.) people whom are casual gamers whom do a fair bit of multithreaded work as well e.g. encoding.
4.) people whom do multithreaded encoding all day as a job/hobby
5.) people whom want their PC to last for as long as possible and will sacrafice performance today if it means having a well performing PC in 4-5 years when multithread applications and OS catch up.
I could go on, but 5 points is enough.
You cannot apply how you personally use your PC to anything here. Enthusiasts are the minority, and any thoughts you have as an enthusiast aren't really AMD's concern. When enthusiasts make up most of the market, then AMD will cater to them.
/scarcasm
Like i know that might sound like me just bieng a jerk, but the fact of the matter is that it is 100% true. CPU cost has no bearing when buying a full system. Final system cost does. If a 2500K system is even $50 more than an 8150 system is, guess which one is going to sell more often than not?
If you are an enthusiast, AMD expects you to overclock, at which point, cost and stock performance is not important, because your costs are much more than the chip anyway, with extra cooling and such figured in. retail cost of the chip according to AMD is $245, and retailers are currently gouging prices hard, by $45 in some instances. That $245 includes markup for the retailer to make money, while OEMs that build systems pay far less because they buy in far larger quantities, and do nto have such large markups. At this point, retail pricing is very much a moot point.
Non enthusiasts, wanting (semi) gamings rigs will go PCWorld or to a local computer shop physically. The shop manager knows that Intel branding fetches for a premium so the entire computer based around the 2500K will be priced higher than an entire computer based around the FX 8150. Customers in PCWorld will happily pay more for an Intel computer than an AMD computer because of brand recognition alone.
I would go as far as saying that a customer would pay more for a lowend Intel I3 than a AMD FX8150. Simpily because they dont know whom AMD is. Shops know this and will mark Intel's prices up.
Slight techy non enthusiasts might say "well I dont know whom AMD is, but 8 cores will last me longer and gain application support as it matures, so I dont need to spend another $1,200 on a new computer anytime soon" - and they would be smart to think that.
When it comes down to a complete system, companies will piece them together in a way to save money but still try and get a maximum asking price.
We in the know how in the other hand know what to buy and how to build. We know how to upgrade and we know how to make a 2 to 3 year old system last as long as possible via smart upgrades and OC'ing.....:toast:

Sorry but the X6 seems better in many games benched here
