Core Solo VS netburst would represent a 40% IPC boost
Correct me if I'm wrong, but I'm pretty sure you're not comparing the same performance tiers there. It's like comparing AMD's budget APU line, to their chips made for avid gamers.

Intel has always had their performance tiers too, like Celeron, on up to the mega expensive Extreme line.

Like I implied above, it's pretty much a moot point unless it's an apples to apples comparison. Otherwise it's about as silly as CPU speed records, which do nothing to account for actual performance.

Plus you guys are making it sound like Prescott actually hurt Intel as bad as Bulldozer did AMD. It wasn't even a scratch to them, let alone a huge impact. Lots of people were still playing on Northwoods, which held up fine well into Core 2 Duo release. Whereas AMD's Bulldozer disaster set them back quite a bit.

Plus Intel learns a lot better from their mistakes. Have you really seen them make any significant ones since those days? With AMD, the Phenom flop was followed by an even bigger one, and their marketing in general is still a mess.

Benchmark Scores Faster than yours... I'd bet on it. :)
Well, are Intel CPU's 40% better in IPC alone? I don't think there is such masive gap...
Check out benchmarks. Specifically the single threaded benchmarks, which when at the same clocks, gives you an idea of the difference in IPC. Look at bulldozer vs Skylake in Super Pi for example. I can take a nap running 32M on AMD. :p
Now you're making it sound like AMD hasn't done anything worthwhile. Even when Core was released, AMD was in very good position with Athlon64 CPU's. The Athlon FX were used in nearly all benchmarks at the time. Even later, they had proper multi-core CPU's where Intel was mostly just stacking up stand alone cores into a single die. Hell, even Phenom processors weren't that bad, in fact the Phenom II X6 were quite highly praised.
When Conroe (the 'core' architecture) came out, AMD was toast from there.

Core solo with a socket adapter was used by a multitude of people to replace the junk ass P4 stuff from s478. It was technically a mobile CPU, but using those to overclock is nothing new. It was also the basis for the core 2 duo's that sealed AMD's movement out of the HEDT lineup.

And even so, I had a Pentium 4 Northwood when I first got into gaming, and it performed admirably until dual core was needed. So there were some standouts in the P4 line.

I seem to remember the 2.4 Ghz Northwood being of good value.

Oh PLEASE, first you compare an 8 core to 8 core 40% boost, to a single core to dual core 40% boost, and now you're claiming I'm ragging on ALL AMD products just because you have no answer for my mentioning that?

You were the one that took the argument 12 years back into product line, while I kept topic regarding AMD specifically to Bulldozer and Zen. So please, stop with the BS.

Again, I'm referring specifically to how deplorable BULLDOZER was, and I still think my point on it was correct. Intel never had to do a same core count increase of 40% to overcome such horrible design. Your example does not take into account the evolution to dual core.

You do know Bulldozer was the first iteration of that architecture and despite AMD admitting it was not what they expected, latest revisions are far from bad. There are countless users who love their FX-8150 or FX-8350 CPU's. Why? Because they are affordable and they still deliver a lot of grunt. You don't like AMD's current offering, fine. Me neither, why do you think I have Core i7 5820K in my system. But that doesn't mean I have to piss all over AMD because of it. They are in unfavorable position and Intel is pissing all over them the entire time in mostly questionable ways. I'm surprised they manage to deliver anything to be quite honest. But they are kicking and even if it's just 40% IPC over Bulldozer and they deliver it in a good package for a good price making it good value, that's great as well. I might not buy it, you might not buy it, but there will be people who will buy it just like there were people to buy FX-8150 and they still use them and like them.

Darling, AMD has always been slower in SuperPi, even when it was a leader in performance in the golden era of Athlon XP. How do I know? Because I was overclocking those puppies and benching in SuperPi a lot back then. And they were always slower in seconds while totally raping Intel in everything that actually matters.

Even back then the instruction set used by superpi was absurdly outdated.

My first own Acer desktop had a Pentium 4 630 3GHz (prescott), it was running al my games at decent fps with a Ati X1950Pro at the time:D
I also did some rendering at the time but for that I needed patience:p

I might not buy it, you might not buy it, but there will be people who will buy it just like there were people to buy FX-8150 and they still use them and like them.

1. Obviously you've not read the countless threads on Steam and other forums where even recent Bulldozer models are performing like shit in a lot of games, and nothing can save it from poor low thread performance. A LOT of games still are not even made for quad threading. It's not all AMD's fault, because clearly devs don't support their chips as well even in a lot of quad threaded games, but AMD kinda brought it on themselves by taking that floating module risk. There's such a small percentage of people using them compared to Intel, that a lot of devs likely don't even play test for Bulldozer.

2. Despite all your defense of AMD CPUs, you still admit you don't like their current offering either, and right after claiming their latest revisions of it perform fine. I'm sorry, but you just can't have it both ways. I'm willing to accept that you'd rather they be more successful for the sake of healthy competition, but that's not really the way you're presenting your argument. In fact, all you're really doing now is contradicting yourself.

3. Again, I'm not here to bash on AMD holistically like you're implying. In fact I've gone on record here many times mentioning that I'm one of the ones waiting to see how Zen will compare to Intel's performance and price before building my next rig, and Skylake's pretty much equal performance to Haswell is a big part of the reason for that, which I've also mentioned many times. Are you living under a rock, or just ignoring most of what I say here?

4. Let's get one thing straight though, a leap of 40% means nothing when you're comparing to same core count, and a design that was crap. If anything it only shows that AMD is FINALLY getting a clue, but it is probably too little too late to save them from always being under Intel's dominance from now on.

I'm also feeling now that 40% is likely best case scenario, and far from average performance gain. Their now saying "targeting" 40%, vs beforehand pretty much assuring it, makes that a bit obvious. Plus, as I also stated, it depends how well devs support AMD's CPUs. Intel obviously has a huge share of that market now. It remains to be seen how much if any Zen will change that.

the 9590 is 32-60% slower per core (depending on the cpu bench) than the 4790k, not counting in the clock speed difference. It is clocked 17.5% higher at stock and 13.6% faster under turbo.

If zen hits 40% more performance per core it will still need insane clock speeds to keep up in cpu benches. However in gaming the difference is only 10-15% on average so even if 40% ipc only translates to a gaming boost of 5-7.5% at similar clocks, it still leaves the gap at 5-7.5% with room for overclocks to make up the rest. That should give enough incentive to budget minded gamers.

To me that is why there isn't a huge server push. Being so far behind in ipc for cpu intensive applications means they simply won't be able to compete with the xeons. However on the gaming front they are much closer and a decent boost plus an economical price is all that's needed to recapture a bit of market share in that area.

Do you think a person who buys an enthusiast grade hexa core on a premium platform with one of the highest end motherboards in a time when most people are still jerking to silly quad cores is the sort of a person who looks for affordable good value CPU? I think not. The same reason why I have a GTX 980 in my system and not a R7 260X or whatever they are named or GTX 950. They might be great value for average users, but I'm not an average user.

Jerking to silly quad cores... Lol you sound like a 12 year old man put your epeen away and stop waving it in people's faces... He may be wrong but you don't strengthen your point by saying hey look at my awesome rig, I'm right and you're wrong... Lol

I didn't read the whole point you two are arguing but the simple fact is that not you or anyone else knows how much improvement zen will have over bulldozer and arguing the toss about who's right or wrong is just retarded.

I hope they bring it, they either will or they won't.... Those are the only factual statements one can make at this time. And it will be bulldozer all over again if they don't... That's a big if either way....

Better performance, OC friendly, good power consumption and of course good pricing. Maybe I will change out wife's 5yr old laptop with one one these Zen platforms.

I had the exact same opinion when I had a quad core and everyone was jerking to dual cores... And there's another funny thing. Everyone measuring their epeens with IPC percentages, but I'm the problem when I mention cores. Like lol...

Rest my case about you sounding like a 12 year old man.... cause you can afford more than some people makes your opinion better? I'm not having a dig btw just saying the whole "I have this many cores and 64GB RAMS, so I am better than you" thing comes off as douchey man, it's not relevant, same as jeb ends in BMW's who think they can drive like wankers and are better than other road users....

Again I haven't read the whole case in point you two were arguing just you seem a lot better than trying to prove a point because your HW is much better than the other guys... that don't mean jack :p

Now let's all wait for Zen and speculate and opinionate, no need to get into the whole my dads bigger than your dad, he said she said playground stuff is there :nutkick:

Good lord what does that have to do with anything I said? I can't keep going tit for tat with you if you keep going off on an off topic tangent, and it's not because I don't have anything relevant to say. Get relevant or I'll just have to ignore you like a dime a dozen mooty tooty.

He may be wrong but you don't strengthen your point by saying hey look at my awesome rig, I'm right and you're wrong... Lol
I'ts not that I'm wrong, it's that he has very weird, abstract ways of trying to prove his point. Some of which have zero to do with anything I've said.
I just hope it's enough to make a difference. Intel's just lumbering around smacking everybody with their dick at this point.
Yep, it's sad, and they don't even have to use a 2' purple dildo like in SR3.

People put too much weight on Ipc but if you add up all the plusses Amd can't go too far wrong ,new cores new fabric ,ddr4 and Smt 40% seams easy enough to me but I honestly expect it to be just ok initially ,I mean it's going to require some software tweaking no doubt ,ie benches ,will they run optimally??,not if Intel's compiler has anything to say about it.

I think that if Skylike is twice as fast as Bulldozer, then Skylake is 100% faster. If Zen is 40% faster than Bulldozer, then Skylake is 60% faster then Zen. No?

Ugh you're right, I'm way off - note to self don't do math when low on caffeine. Let's try this again. We compare performance relative to a single Skylake core. The BD core has half the IPC. When we multiply that by 40%, we'd still be at 0.5 * 1.4, -> 0.7.

That would mean that in the best case scenario (according to AMD), a single ZEN core would be about 30% slower than a Sk core, as long as the frequencies of both remain relatively the same to one another. It kind of sounds like it'll perform somewhere around Sandy Bridge. I'd still consider that good, as long as the price is right.

from Anandtech: (btw how can I make the image smaller? )


Sandy Bridge to Ivy Bridge: Average ~5.8% Up
Ivy Bridge to Haswell: Average ~11.2% Up
Haswell to Broadwell: Average ~3.3% Up
Broadwell to Skylake (DDR3): Average ~2.4% Up
Broadwell to Skylake (DDR4): Average ~2.7% Up

The above is a bit generous. If we focus only on Cinebench ST improvements, performance increases only about ~22% from Sandy to Skylake, or in another way, Sandy's single core IPC is 82% that of Sk. ( 1/ 1.22)

Wow... I see forum post like this I cringe... AMD P&CEO never said the word "Targeting" she did say that Zen was on track to deliver "Greater than 40% increase in IPC" Also at the financial investment day us stock holders were told that Zen clock for clock is twice as fast as an 8350. Seems like it's all looking great.

Wouldn't it be easier to check single threaded CPU scores for relative IPC and just compare similar clock speeds between the architectures. Steamroller is clocked on par with Skylake, and is around 5-10% behind Excavator in IPC. The provided SKUs should offer a reasonable comparison (bearing in mind allowances for overall platform differences)

The 40% increase is related to Excavator not Bulldozer (this was actually clarified by AMD on one of their sheets). Therefore it's easily over SB IPC if it's true. AMD themselves stated 40% over Excavator or ~100% over Bulldozer (as in sheets). Seeing as the new CPU will have 8 real cores and 16 threads, compared to the 8 wannabe cores (or more like 4 cores / 8 threads in CMT) of Bulldozer i'd say that could be true.

Plus you guys are making it sound like Prescott actually hurt Intel as bad as Bulldozer did AMD. It wasn't even a scratch to them, let alone a huge impact. Lots of people were still playing on Northwoods, which held up fine well into Core 2 Duo release. Whereas AMD's Bulldozer disaster set them back quite a bit.

I fail to see the difference between the P4 and Bulldozer debacles. You make it sound as if no one is getting by on Bulldozer and Steamrollers. While they aren't as good by any stretch of the means, you can still accomplish any task perfectly fine with Bulldozers and Steamrollers. One reason Intel may not have been scratched during the P4 days is because of their strong-arming of OEMs that they had to go to court on.

EDIT: Anti-competitive practices rather, which may or may not have been horseshit. But somebody didn't think so.

NOTE: This is not an attack please don't treat it as such.

Being so far behind in ipc for cpu intensive applications means they simply won't be able to compete with the xeons.

There is more to performance than just IPC. IPC isn't a tell all indicator when comparing different architectures.

Well, are Intel CPU's 40% better in IPC alone? I don't think there is such masive gap...
There actually isn't when it comes to core performance. However, AMD's current cache design hampers things a lot, which makes it equate to that roughly 40% give or take 10% in single-threaded applications. Just take a look at the difference in memory bandwidth at the same speed on DDR3, or on DDR4 with AMD APUs... it's half of what Intel manages with the exact same memory chips. All of the problems there add up to AMD being quite a bit slower than Intel, but at the same time, AMD isn't on the same node as Intel, so who cares? Only those that benchmark...

But, that doesn't matter, since Zen is supposed to be an entirely new core design. So whatever AMD did in the past doesn't matter.

To me, the telling thing is that they are "on track", which means they need to meet a yield expectation in order to offer such performance benefits. I said long ago that is was clear that AMD's "bulldozer" and such iterations were intended for 5 GHz, and in the end, that's the chips we got... 5 GHz. The only problem is that it took too long for yield to mature enough for them to bring in enough silicon at that clock speed. Intel's sitting fairly pretty with a core design that is destined for 4.6 GHz, as I also said in the past, and the years since SandyBridge have shown that 4.6 GHz as the average overclock users can expect with good chips. We know that Intel's silicon is much more advanced than AMD's (and I mean the sand; the wafers; not the chips), but as AMD has gotten access to better silicon, Intel seems to have been running into more and more problems...

If AMD can release a decently performing chip with 8 cores that matches a 4960X, but sells it on the cheap, they'll do really well. Time will tell what they get in the end... they don't make their silicon, they simply design stuff that utilizes other company's silicon, so you can't fault AMD if they miss their target because of poor yields... you blame their foundry partners. AMD doesn't blame others, though, as that's bad business.

Intel continued to thrive under Pentium 4, AMD's fortunes under Bulldozer...not so much. AMD's x86 server market share - thanks to the server orientated Bulldozer/Piledriver is at an all time low of less than 0.7% - the lowest figure since AMD entered the server market with the debut of Opteron in 2003.
Time will tell what they get in the end... they don't make their silicon, they simply design stuff that utilizes other company's silicon, so you can't fault AMD if they miss their target because of poor yields... you blame their foundry partners.

I'm not so sure about that. AMD has publicly laid blame at Globalfoundries door on more than a few occasions - well deserved given Glofo's rather creative predictions, but AMD haven't been shy in letting the market know why the volumes and top bin parts were M.I.A.
