AMD Carrizo Pre-release thread

[-sandro-]

If all you wanted was lower price and watching movies, how does the 15W TDP affect you?

I don't watch movies but edit 4k files... so CPU power is also important.

Any word on Carrizo Itx Boards yets? Time Frame we are look at? I couldn't find anything new but maybe one of you insiders know something?

Uh, that's questionable. The Stilt mentioned that Sapphire has some development boards out there for insane prices, but I was unable to find one for sale on the general market. That's probably not what you want anyway. Given the poor supply of Carrizo lappies in North America (assuming that's where you are . . . ?) I would not hold your breath waiting for it.

Carrizo-L could theoretically wind up on AM1, but again, don't hold your breath. AM1 is a decent seller in markets that are not NA/Europe. So if it shows up anywhere . . . it won't be NA first.

Is mITX a requirement? mATX board + 7670k + undervolt would probably be your best bet. According to The Stilt, clockspeed/watt favors GV-A1 Kaveri at clockspeeds above 2.6 GHz. I can get an older stepping of Kaveri stable @ 3.4 GHz with only 1.075v vcore and around 1.15v vNB. You could roll back a 7670k's base clock to about 2.8 GHz, let it turbo up to maybe 3-3.4 GHz with a tool like amdmsrtweaker, and keep low power states active for something that would sip power. It would probably stay under 35W for the entire system assuming you used SSDs.

Hump? Do you mean Bump? LOL lots of difference there.. Any ways, heck yeah it would be cool to see some new cpu's get released for AM1. Personally I wish they would release a new socketed AM1 maybe call it Am1+ and release Carrizo or Carrizo-L and DDR4 support. I have a Asus Am1 Itx mobo and a 5350 and love the shit out of this little monster of a Pc. I guess the Older I get the cheaper I get

 

[monstercameron]

just picked up carrizo, tell me what you want to test.

 

[Justinbaileyman]

Please test Handbrake first!! also what variant did you score 15w or 35w and is it in laptop form or itx form? I will literally shit bricks if you got a itx.. could you please post some pics maybe??

Model of laptop and specs ??

I spent some time today researching and compared the only benchmark available from notebookchecks for the A10-8700p at 15W. I can see that the Broadwell I5-5200U at 15W destroys the AMD APU basically in every single task, except for graphics of course.
So considering that laptops with same specs except half HDD size (don't really care) are priced the same and that Skylake will also support HEVC in hardware I don't really see the point for me (and everyone else who doesn't care about games) why I should give my money to AMD for less performance.

I bet that the only systems with 35W will be those high priced gaming laptops.
Is this thinking right?

toshiba satellite radius 14", fx-8800p, 8gb dual channel 1600mhz ram, 15W config {cpuz}, 768p screen $599 bestbuy.

Lol i wish it was a mini itx system, then I wouldn't ave to buy another laptop. Now I can compare carrizo and kaveri. Im also going to dig up the handbrake benchmark from this forum.

here are the results http://forums.anandtech.com/showpost.php?p=37718422&postcount=422

maybe, but for me the amd system is different that what else is out there and I see value in that.

Care to explain?

I hate AMD even more now.

Sounds like good reasoning. I think that AMD is having trouble getting the laptops to be competitive in price. (Or widely available, for this matter.)

Personally I would still get a Carrizo for gaming purposes if one was offered in a 11-12" laptop.

I'm still sore about the big review sites (such as Anandtech) not reviewing Carrizo even though it's been available to buy for a while.

In Europe I've seen only the HP Pavilion 15 and 17.

Aida64 mem/cache and instruction latency tests would be nice to get some arch related differences.

According to Stilt at 3.4 Ghz, Steamroller has a 9.1% power consumption advantage over Excavator --> http://www.overclock.net/t/1560230/jagatreview-hands-on-amd-fx-8800p-carrizo/520#post_24343181

...but then Excavator also has a small 5% IPC advanatage right?

So this processor really isn't that much worse. And it does have a DDR4 memory controller on die (not yet enabled by AMD). Plus it is fully HSA compliant.

Hmmmm......with DDR4 2133 memory prices on par with DDR3 2133 prices I have to think a DDR4 BGA Carrizo might be the one to go with for Mini-ITX users.

 

[cbn]

Doesn't the GPU on Carrizo also have some power consumption improvements on the micro-architectural level compared to Kaveri/Godaveri?

So this should also help balances out some power consumption differences at moderate clock speeds.

With that mentioned, I do hope we can eventually get DDR4 on these Carrizo...because that will only help more and more as memory prices drop.

And if you just want ITX there is plenty of options. Even regular Kaveri chips from AMD as well or pretty much all chips from Intel.

Right now I own a MSI A88X Mini-ITX board (bought it on a rare super sale so the cost was reasonable), but normally this form factor for FM2+ is rather pricey.

I think having BGA Mini-ITX for Carrizo would solve some of those cost issues (at the expense of some features like SATA ports).

I can have kaveri fx-7500 numbers tomorrow.

Thanks. So in PhotoWorxx your FX-8800P nearly beats a higher clocked Phenom II X4 Black 940?

There is also a hidden feature to get the instruction latency dumps.

These lists were created by AIDA64 Instruction Latency dump feature. [...] You can create such dump in AIDA64 by right-clicking on the bottom status bar of AIDA64 main window -> CPU Debug -> Instruction Latency Dump. It fully works on trial version, too.

This should create some text files.

You might be the first to provide these Excavator numbers to this site:
http://users.atw.hu/instlatx64/


And I'll dig out my old BD analysis tables to compare the results to see any AVX or other improvements.

BGA wont solve what is a volume problem. Remember how utterly tiny AMDs share is.

running it right now but it locked up at 1973 of 2500, didnt know x86 had over 2000 instructions.

So, seems that AMD Carrizo ended to be as crappy as Broadwell... Definately 2015 is an age to forget in the tech world.

And that Memory bandwidth... Far worse than a Nehalem!
So Bristol Ridge won't reach Sandy Bridge levels.... What a dissaster.

you know alot of nahalem chip were triple channel right?

@dresdenboy here is the instruction latency dump http://pastebin.com/Veap64CV

avx2 instructions.

AM1 Mini-ITX boards were low volume....and they were cheap.

Carrizo should be a lot simpler to implement on Mini-ITX than FM2+ owning to the integrated chipset and limited features.....so it should be cheaper also.

The question is can the OEMs give us a Mini-ITX BIOS that allows the most (or all) of the CPU turbo clockspeed to be used while the GPU is under load? (This would increase TDP beyond 35W).

That.....and we really do need DDR4 as well.
