You seem to be out of date. Piledriver is ahead of Thuban in pretty much every way already.
 
[citation][nom]ta152h[/nom]IPC latency? Were you drinking when you made that up? It makes no sense.They basically castrated the integer units for the Bulldozer and Piledriver, and then added another one to make a pair. Consequently, the only way to get good integer throughput is to use two threads per core, or you just have a lousy processor. But, of course, the decoder can't keep up with two threads at the same time, so basically you have this crummy processor that performs worse at everything compared to the Intel processors.On top of that, AMD still hasn't learned how to make a cache. They have a puny 16K L1, but it's still slow, and makes the processor much more dependent on the L2 cache. The L2 cache is catastrophically slow, and is only exceeded in ineptness by their L3 cache implementation. In short, AMD's Bulldozer/Piledriver chips suck donkey balls. So, if you meant their cache latency is killing the processors, and exacerbating already poor IPC caused by castrating the integer unit, I'd agree. It's a remarkably poor implementation, being quite large, very slow, and consuming massive amounts of power. It took a lot of engineering talent to make a modern processor that bad. Piledriver helped, but the basic design and slow cache limit this lousy processor severely.Steamroller could fix a lot of sins with a better decoder, restoring the ALU in each integer unit, and making a cache system that works. The latter of which is nearly impossible, since AMD has no idea how to implement an efficient cache, but maybe with Jim Keller there's hope. I'm pretty sure they'll improve the first two, but if the cache continues to blow, it's going to severely limit the performance of the processor. I'd settle for even a moderate improvement, which is possible since the BD/PD has significantly lower performance than the Thuban had. Just get us back to Thuban, and it will help a lot.[/citation]

I am dumbfounded that you actually believe AMDs Vishera is behind Thuban which every bench out and every test we have run shows the FX 8350 destroying the 1100T across the board, the FX 6300 basically matches the 1090T/1100T or thereabout. And this implied gap you are trying to make out between Intel and AMD is ficticious at best. Apart form Civilizations V Intel and AMD are very close in overall performance.

What makes this bad for intel is that 11bn in R&D can barely best a sub bn dollar R&D. iGPU wise AMD is over the hill and far away, it would be pointless to even talk about this. All current innovation and technology is from AMD, intel well modest iGPU, haswell and ivy bridge E delays.... AMD, fastest tablet with full HD quality and windows 8 support, kabini based notebooks with iGPU's that make HD4000 and soon to be GT3 look rediculously overpriced in Ultrabooks with now nvidia support those Intel parts are going to get consumed by AMD's vastly superior iGPU performance. Richland APU's deliver 5% x86 gains and 22% iGPU gains, added to that is dual graphics support will extend to GCN compatibility as well as be backward compatible with VLIW parts. Contrary to what the Intel fan crowd is lead to believe AMD is doing very well all things considered.
 
[citation][nom]madjimms[/nom]You forgot that Intel's compiler is extremely biased toward its own chips & many software companies use it. "Not genuine"...[/citation]As long as Intel's compiler beats all other compilers even on AMD processors, this is not going to change.

The courts had it wrong. They needed to force Intel to remove the vendor check, not put a sticker on the box, so to speak, saying that the compiler may not work optimally with non-Intel processors.

From the information I've seen, Steamroller looks like this:

+ More instructions per clock, thanks to a) µops queue, b) more ISA support, c) caching improvements etc.
+ More instructions per module, thanks to the decoupled decoders - no more disabling one core per module
+ Reduced power consumption, thanks to a) 28nm process and b) dynamic L2 resizing
+ Smaller FPU - fewer transistors for the same performance

- L3 cache not completely fixed; AMD doesn't believe it makes much of a difference in the server world (plus most FX CPUs will be L3 cache-less APUs), so we might be talking Excavator for this
- High density libraries coming with Excavator, so we'll have to wait for a true drop in power, albeit with a possible clock speed drop at the same time

you are definitely drinking the intel coolaid , crummy processor ??? in gaming the FX chip holds pace with the top i7 (see previous tom's benches) , the I7 only beats it in work applications , and considering price points the amd matches or hands down beats the i5's that are in it price range. and let's face it ... the average joe is NOT going to spend 500 bucks to 1000 on a processor. even the average gamer at most is going to spend 150-200 on a cpu , and in this price range AMd's FX line is great, considering how it handles work apps better than the i5's ( such as 3ds max and autocad) .

Lastly most intel based main boards that are worth a flip tend to cost way mroe than simularly specd AMD main boards which makes the saving of an FX over an I5 all the more apparent.

I'm not trying to blow smoke up any one's butt here , nor am i licking the AMD lolipop. just stating facts. for it's price range the FX chips are not bad buys, paricularly if you are a gamer that does mod work in 3ds max , or a developer that likes to game on the side of work at home.
Sure if i want a super do it all PC, and the company i'm working for is footing them bill. or some miracle i get the m oney to afford it , I'd go Intel I7 for sure ... but at 500-1000 bucks compared to amd's top end at 200 , i just don't see the value in it with my current bank account numbers.
 
Incorrect headline, it should be announced/unveiled not "developing". We've known they're developing Kabini for ages now.

Also, people: note that the new piledrivers aren't 28nm.
 
[citation][nom]acerace[/nom]Downrating makes someone's post look bad, even though it has a very good point. Like you said, downrating troll, and the system is very broken.[/citation] yeahh my post got downrated off visbility and some dude quoted me and still didnt like well... add anything. for some people the comments seem to be a battle ground.

I see the same posters who downgraded people for complaining about the 7970m which had a plethora of issues not addressed and even asked to hidden away by amd themselves on other sites.

people on here downrated people who had the product argued against reality every fact was something to have an opinion on and well... toms eventually did apologize to the users who complained. still didnt stop all their post being downrated into oblivion. and the most liked post were ones of some dude making up nonsense. i mean the facts were there... the people who complained were legit but it didnt matter on this tom's hardware rating battleground.

i dont find this rating system constructive to making conversation like a forum.

I stated prices, performance, dislike for the level of the performance based of what is available. i play games, be it on a tablet or laptop. amd's not offering a competitive product being in the same price range. and i talked mobile only. being specific on a platform and price point, you have to offer a bit more.

well ill apologize to the amd fans, i am a former amd fan also; that the fact that i want to see a competitive product, on the platforms and price points im seeing and discussed.


 


In gaming, there's usually a far bigger deficit between the FX-8350 and the i7-3770K than there is in most professional work. When they're close, it is just because of the CPU performance not being important enough for the big difference to matter, or somewhat increasingly common, you're playing in a situation where the game is actually scaling quite effectively.

Furthermore, don't forget that most people talking about i7s are talking about quad core models, not six core models. They can be had in the mid $200s to a little over $300 and for gaming, even the slightly under to somewhat over $200 i5s are no different most of the time.

Motherboard cost difference isn't nearly as bad as many people try to make it out to be. Cheap AMD boards are mostly just more likely to have better connectivity and since most people don't make use of more than two SATA 6Gb/s ports (or even more than one) and similar situations, that's usually not a big deal except for a few more specific uses such as cheap systems where a lot of high-speed drives is important at a low price.

FX does have some well-priced models even for their gaming performance, I'll give you that much too. However, the same can be said just as well about Intel.
 
Well damn, I just bought a FX 6300 :-\ same thing happened to me when I bought my Galaxy Note 2 and TWO days later they announce the Galaxy S4!*sigh* screw keeping up with the " Jones 's", it's waay too costly! 😛

^How the heck do you miss a GS4 launch if you read tech sites? And if you only needed what a GS4 offers, why the heck are you buying a Note 2? A phone in a different market no less. It seems you're clueless when it comes to tech, so just off yourself. You're clearly using what brain you have left to just breath.
