AMD Unveils Carrizo APU With Excavator Core Architecture
MojoKid writes: AMD just unveiled new details about their upcoming Carrizo APU architecture. The company is claiming the processor, which is still built on Global Foundries' 28nm 28SHP node like its predecessor, will nonetheless deliver big advances in both performance and efficiency. When it was first announced, AMD detailed support for next generation Radeon Graphics (DX12, Mantle, and Dual Graphics support), H.265 decoding, full HSA 1.0 support, and ARM Trustzone compatibility. But perhaps one of the biggest advantages of Carrizo is the fact that the APU and Southbridge are now incorporated into the same die; not just two separates dies built into and MCM package.
This not only improves performance, but also allows the Southbridge to take advantage of the 28SHP process rather than older, more power-hungry 45nm or 65nm process nodes. In addition, the Excavator cores used in Carrizo have switched from a High Performance Library (HPL) to a High Density Library (HDL) design. This allows for a reduction in the die area taken up by the processing cores (23 percent, according to AMD). This allows Carrizo to pack in 29 percent more transistors (3.1 billion versus 2.3 billion in Kaveri) in a die size that is only marginally larger (250mm2 for Carrizo versus 245mm2 for Kaveri). When all is said and done, AMD is claiming a 5 percent IPC boost for Carrizo and a 40 percent overall reduction in power usage.

Sure it improves on the previous generation of nobodywantsme type architecture, but unless they go on sale tomorrow for $59, i'm afraid it's mostly harmless.
I am intrigued by the potential of HSA, but are there any examples of it in use?
Excavators!!!! Yipppeeeeee!!!!!!
workin on the Linux drivers .. or atleast letting someone else work on them ..
Reducing wattage on an APU means more battery life and putting the southbridge on the chip lowers the cost and allows increased customization
options.
what does this meant to me, the average user?
Like this bad mother fucker right here.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
Bulldozer (2011)
Piledriver (2012)
Steamroller (2014)
Excavator (2015)
Dildozer (2016, planned), which will feature the Beef Supreme driver

Don't you mean "not just two separates dies built into an MCM package"?

You do realize that is 4 computers in one box right? Like literally the equivalent of 4 1u servers with 2 CPU and 3 GPU but turned on their side. Also that it costs nearly 100k, which is approximately 50 times as much as an _entire_ computer based on this APU would cost.
Also, considering that with your computer you are getting 12 cores * 4 machines for $100k, where as with an APU based machine you are getting 4 cores * 50 machines, and each of those cores is clocked about twice as fast (4.3 vs 2.4ghz).
who thinks the name is horrible?
I agree, and I think that people who harrass others online or make inappropriate 'troll' posts should be sentenced to death.
By having smarter designs obviously, Intel has always been about brute forcing it.
While we're at it, let's revisit the price of eggs in China for a minute...
For the record, AMD is also moving toward a hybrid stack for the Linux drivers:
- the same opensource kernel driver is used every where.
- the only difference is that either you run the official catalyst OpenGL implementation from AMD on top of it. Ot the opensource Mesa Gallium3D tracker.
- same goes for video (either a VA-API implemented by catalyst, or the various Gallium video state tracker).
So except for the 3D and Video, everything else is opensource and work is shared.
From the development point of view, AMD hardware is faring very well. GP doesn't need to be afraid.

And Intel would still be forcing the Itanium on us had AMD not come out with the Athlon and the x86_64 instruction set, stealing Inel's lunch for a few years until they caught up.
Sure, AMD dropped the ball and Intel stole the lead back from them years ago. But without the competition, Intel wouldn't have any incentive to have processors as good as they do now. The market needs companies like AMD to keep companies like Intel competitive.
The Steamroller cores are really not that bad. I made a Kaveri system for my brother with an SSD and a relatively cheap motherboard and it runs really, really well while using less than 100W at peak. At $130 for the CPU I got 3 digital video outputs and decent video performance for casual gaming, so I think it's a very good product. We can argue benchmarks all day, but at that price range, I think AMD is a very viable option. We'll see what excavator brings to the table, although I don't think a desktop version is coming.
1) Anyone that uses synthetic benchmarks like Cinebench deserve whatever they get. These things have been rigged since the ATI VS nVIDIA days, and ATI doesn't even exist anymore. Not to mention they don't really prove anything.
2) Using real world software tests, particularly in gaming, Intel has been blowing AMD out of the water since just after the Athelon64 days. The only places that AMD has has success commercially or in performance has been in A) The server market, and B) the very low end market, the later you wouldn't bother or care about benchmarks anyway. Yes it could be that a lot of software is optimized for Intel, but then again, if one is faster than the other because of the lack of optimization then it is a moot point anyway. AMD is better in some unique situations than Intel, but out of say 20 software tests, it might excel at 2 of them, so it is pretty specific software.
So stop drinking your own fan boy coolaid. I for one would welcome a more competitive AMD CPU, as Intel has been driving prices up due to a lack of real competition. The buying of ATI by AMD was supposed to re-invent AMD and harold in a level of integration of video and cpu. The only thing that has really happened is that integrated video has gotten slightly better. and AMD has a video card division now...
