AMD Carrizo Pre-release thread

[therealnickdanger]

Does anybody know why there are no reviews of Carrizo from any major review-site like Anandtech? Carrizo notebooks have been out for a while now and all I could find was a review from the German Notebookcheck.

I think someone said earlier that AMD intends Carrizo to be reviewed alongside Windows 10, even though it officially launched a little earlier. Either due to drivers or other optimizations/power savings, I don't know, but I recommend that you do like I'm doing. Be patient and avoid this thread as best you can. LOL

The more i look at it the less i understand NBC half review of the 7410.

Believe me, is not the first time NBC raises doubts with its tests.

I'd like to know this also. Why isn't AMD sending out review units? Typically when AMD tries to control information like this it's because something is not living up to expectation - such as the staged Bulldozer launch.

Apparently they are sure of their numbers being accurates, although if i were them i would send those retail products myself, just to check if there s not an OEM that did screw the things, or to keep some reviewers to make up numbers like in the NBC Carrizo-L 7410 "review"...

Somebody on this board should go buy a Carrizo laptop and do some testing.

AMD probably knows that barring Carrizo turning out to be a massive improvement over Kaveri, a full press push would just get overshadowed by Skylake's launch. On top of that, everyone now knows that AMD's long-term strategy is based around Zen.

Carrizo is likely AMD's version of Cedar Mill; it might be a decent improvement over it's predecessor, but it'll be widely seen as the last gasp of a failed architecture, and make little impact on the marketplace.

Yeah, we just have to find a trustworthy public review first so we know which one to get...

that might still be 2 months out for me...too many gadgets.

I know the feeling

If you do pick up a Carrizo laptop, though, it would be fun to see a thread in which you put the thing through its paces!

At some point there must be some food brought on the table, no one does something for free..

It is a good uarch, those who say otherwise dont take account that it s still 28nm, the CMT concept proved to be good , we are far from the raw design that was BD.

Also your comparison with a lowly performing in order uarch is senseless from the start..

 

[dark zero]

Actually Carrizo is like the Phenom II. Is decent and can fight Intel besides the real Quads.

But won't last that much and Zen is about to come

Also your comparison with a lowly performing in order uarch render is senseless from the start..

a good launch probably means from a marketing perspective, not tech. Also the comparison wasn't directed at carrizo, don't be so aggressive.

Pentium 4 and its derivatives were OoO machines.

Agree that i jumped quite rapidly, but one has to put things in perspective before doing a comparison.

At the time Cedar Mill was competitive with about nothing set apart against its predecessor, that s not the case at all for Carrizo, so that s why i criticised harshly this POV wich is tengential to say the least.

As for marketing AMD has done most of the effort, they disclosed caracteristics at the ISSC and provided infos about the SKUs at Computex, i dont see what they can do more than sending a few retail products to a few selected sites like AT or other NBC.

Main effort should be directed at the OEMS to get them releasing smaller formats like 13"3/14", suspiciously (how can it be qualified otherwise.?) there s about no such offering for any AMD APU, excepting the hefty EliteBooks there s only one HP at 13"3 and one Lenovo at 14" both using a Beema 6410, that s all.

So much for my memory, i thought that it was an Atom iteration, apologies for the confusion to the member i criticised.

The P4 uarch IPC didnt increase much IIRC after Northwood (wich i have in a still functional laptop), extended pipelines eventualy increased perfs through frequency uplifts but at the expense of huge penalties in case of misprediction wich likely did neuter uarch improvements.

So even this comparison is not very accurate, on FP for instance an Excavator module has 30% more throughput than a BD module, a little less in Integer at 20-23% but still respectable numbers in comparison of the full P4 evolution.

As far as I remember, Intel actually saw IPC decrease post-Northwood. They made a number of uArch improvements but you're right -- they lengthened the pipeline significantly (20 stages to 31 if memory serves), but weren't able to get significantly better clocks.

It was a mess.

Northwood was a good processor since it improved IPC over Willamette and delivered better clocks (I had a 2.4GHz Northwood back in the day and it served me well), but every other P4 iteration after that was decidedly inferior to AMD's solutions.

And Northwood brought SMT.

 

[NTMBK]

Northwood was a solid processor. My parents still have one in their backup PC. I still wonder what would have happened if Intel had doubled down on IPC after Northwood, instead of chasing the Prescott pipe dream.

Firstly, it's a bit premature to say that Carrizo is (or isn't) going to be competitive with anything when we still have so little information on how well Carrizo or Skylake perform.

Secondly, you missed the point of what I was trying to say. I wasn't claiming that Carrizo or Cedar Mill were similar from a technical standpoint - heck, Carrizo is exclusively a mobile chip, while Cedar Mill didn't have a mobile version at all - but that they're similar in as much as they represent the fourth and final major incarnations of their respective architectures, and got little fanfare from the press and even their own creators. AMD might not have let Carrizo's launch go completely under the radar, but compared to both Trinity and Kaveri it's been a very low-key affair.

 

[shady28]

Pretty sure the original Pentium was the last in-order execution processor Intel made... until they made Atom. The Pentium Pro P6 uArch was their first out of order x86 CPU.

Wikipedia on the P6 :

"Speculative execution and out-of-order completion (called "dynamic execution" by Intel), which required new retire units in the execution core. This lessened pipeline stalls, and in part enabled greater speed-scaling of the Pentium Pro and successive generations of CPUs."

"Low-key" is overstating it, I think. To go over a month with only the same marketing slides as reference is a terrible way to launch a product, especially one that is supposed to have such promise. In light of the recent Intel CPU yields debacle/delay and Fury X falling short, you would think that AMD would be tripping over itself to get as much positive press as possible.

Does this even have Carrizo?

 

[frozentundra123456]

I dont even see that model at all when I go directly to the Lenovo website. Is it maybe Europe only or something?

Probably just unreleased. Maybe in a month it'll pop up in retailers
