AMD Carrizo Pre-release thread

[USER8000]

I don't think anyone knows for sure if Carrizo uses Tonga-like color compression. It might be in some of the Carrizo release slides. Regardless, it seems like something like that has come into play.

It does.

P2750 is the score of my 45W 750M

needs real world perfs, seems a little too good to be true

I agree with Abwx, for whatever the electrical engineering reasoning, when it comes to Intel's 14nm the promised goods have simply yet to show up. Not a good sign when they are well more than a year into HVM on the node.

It suggests they have/had a lot of reasons to go quiet on 10nm. Sure they have successfully spun it as a strategic decision, competitive advantage, etc etc...but the 14nm situation is proving out to be a bit of a 90nm déjà vu thus far.

90nm was perfectly fine for Pentium M. So with 90nm it seems it was more a design issue than a node issue.

One could also say Samsungs 14nm is a flop, when looking on 20nm to 14nm benefits on their Exynos SoC.

Agreed, we need a lot more info. we have seen plenty of performance figures from both amd and intel on early data on reference platforms that didnt hold up later in real world devices.

Damn lets hope they will come back - they have shown they can historically.
So its not a result of the capex reduction the last years?
Do you have any guess to the reasons?

Intel and AMD are definitely raising the profile of the APU as gaming and computational devices. The real loser here (if any) is Kaveri/Kaveri refresh. That APU is being left behind.

They quoted 5-7% perf improvement via delta color compression tech.

At 1080p IIRC.

Newer nodes never make any miracle in power consumption of the chips.

 

[ph2000]

It'll certainly be nice to have some competition on the x86 market, hopefully Zen lives up to its hype, if it does, I'm building a tiny gaming rig on it.

hopefully amd wont need several generation to make it right with Zen

 

[pablo87]

The realization on Carrizo gpu performance, they can't make a desktop part much faster, bottleneck remains memory.

Therefore, future APU's will be mobile first, "desktop" will be whatever they can extract out of the process. Which will be fine for 90%+ of buyers given that you have Zen CPU and discrete GPU's for performance And that 90% will approach 100% as buyers realize a Zotac type Carrizo literally pays for itself in electricity savings (minus the OS).

Moreover, the memory bottleneck gets addressed by HBM (PS shocking that only 30% or so of DDR4 die is memory array) If it was available now we'd probably have Carrizo D and Carrizo H. And overall, pent up demand for display computing power >>> compute in Consumer at least.

Makes complete sense - AMD tried to do too much and the resu!ts were disastrous. Now its CPU, GPU, mobile APU.

ps - the Premier of China should send a couple of students around to measure typical power drawn by PC's with integrated graphics and then ban those that consume more than 50W. Probably save a few gigawatts of power.

 

[Abwx]

Actually I don't really I just hope there will be a 14" 1080P notebook that fits my needs. That's all I'm asking for. :ninja:

Well, with dual graphics...if you live next to Germany.

Models start as small as 14-inches up to 15.6-inches and 17.3-inches with 768p and 1080p display options. Users will also be able to choose between AMD A10 or FX processors with Radeon Dual Graphics or Intel Core ix and Nvida GT840M GPUs.

The new Aspire E noteboooks are available now starting for 499 Euros. The 15-inch model with a Full HD display, dedicated GPU, and primary SSD will start at around 780 Euros

I live next to Germany. ()
I don't want dual graphics though if that means all efficiency is gone because they chose to put Oland garbage in there. GCN 1.0 shouldn't be paired with this...
If it is a newer gpu I'm okay with it probably.

What kinda sucks though is the German keyboard I actually ordered a Kaveri Lenovo laptop from Germany and it was horrible mostly because despite me putting it on US-English layout the top buttons weren't aligned and a ) turned into a ( because the offset was 1 key it sucked.

I m also close to Germany and those non transposable dedicated are more than annoying given this country well funded tech markets...:|

Heck, one of their low cost food supermarket made a promotional offering on a Kaveri DT just a few weeks after launch, there s some brands like Medion or Eurocom that are mainly sold on the german market, no wonder that they ll surely get the first well made Carrizos in Europe..

Yeah I know the Aldi we have it here in NL too. Anyways Medion isn't really that good a brand. My old Medion 2670qm gt555m laptop while decently speced had the worst screen, trackpad and keyboard imaginable.

Had a Medion PIII 667 that was falling apart as time was going by, but on the long run a much better investment than a 2x pricier one, at the end it would had also ended in the trash bin, in a better physical shape though...

There is the i7-5775C which has been seen in the wild clocked to 4.8 ghz and higher. The mere fact that it can even boot at those speeds with air cooling shows that there is not an absolute clockspeed wall up there.

I would like to see more samples doing the same thing (or similar), but I think it's naive to entirely discount what was reported by HKEPC.

They quoted 5-7% perf improvement via delta color compression tech.

Okay, I must have missed that, but that's okay. Carrizo is quite the little performer! AMD better sell the heck out of those things.

I continue to believe that report was false: while BW may be able to clock that high, I really doubt it can do so at that reported voltage.

The OC screenshot shows a 5Ghz at 1.42V. Let's say at same voltage 4.8Ghz was stable. We also know now that BW 5775C needs 1.2V for 3.7Ghz. On the other hand Haswell needs ~1.2V for 4.4Ghz and around 1.45V for 4.7Ghz. Let's say 4.8Ghz for comparison sake.

So we have:
BW 1.2V@3.7Ghz ----> 1.42V@4.8Ghz
HW 1.2V@4.4Ghz ----> 1.45V@4.8Ghz

Maybe BW doesn't have to deal with the voltage barrier HW hits around 4.6-4.7Ghz. But then again, maybe that report wasn't quite accurate on the voltage side of things.

Stock voltage settings leave a lot to be desired. Perhaps the 5775C can run up to 4.2 ghz without any voltage increase? It depends and unless we get some hard results it is difficult to make a comparison.

I guess we'll start getting results from forum members soon enough, even if reviewers were somewhat shy to overclock them so far.

 

[DrMrLordX]

Seems like most of the reviewers are distracted with Computex. I eagerly await more OC results. I agree that Lam might have had a Golden Chip(tm), and that the voltages are off. We just don't know with such a tiny sample size.

 

[Paul98]

When are full reviews expected? Sounds like it's going to be a nice product, I would like to find something I could use till we really get a massive APU upgrade on a new node and using HBM.

 

[piesquared]

AMD's engineers did an awesome job building Carrizo. It'll be the chip I'll have in my next laptop for sure. Really looking forward to using Looking Glass too.

Probably but let's wait for the reviews shall we. It sounds amazing but no reviews on the release date is bad news :\

They have the notebooks why not hype the hell out of it by throwing numbers around

 

[frozentundra123456]

Paper launch perhaps??

 

[el etro]

Paper launch perhaps??

More or less. There's no soft launch because there's still no reviews, but the chips are done.
