I see people say this, but what is the deficiency that AM3+ cannot do but the FM2 platform is somehow able to? Both have PCI-E 2.0 which comes from the CPU and additional lanes with chipset upgrades, both have dual channel memory, both have full IO stuff with USB3 support and such and more can be added with new chipset, both can have integrated graphics, both have SATA6, both can support high power CPUs. So where is the deficiency that FM2 is able to solve but AM3 cant?
AM3+ is fine. It needs a new chipset maybe but the pins and socket are fine.
The same kind of people who say AM3+ sucks are the same people who think PCIe3.0 makes a huge difference and that buy mainstream Intel platform over LGA2011, because LGA2011 uses PCIe2.0.
Seronx I do not understand, are you implying a 6 module single die chip? So the good chips that are fully enabled will actually be the 6m/12c ones while the 8m/16c are two 6 module parts with modules disabled? Why is there no 24 core then? Just not worth it to put two 6 module CPUs on a single socket?
I do guess that explains why there is no 8 core chips floating around. Instead of selling chips that need modules disabled as FX 6000 or FX 4000, they could just put them on an MCM package and charge even more for them than the good chips that have full working modules.
It does make a lot of sense I suppose. A big chip like that at a high frequency would use a lot of power. I realize this is sloppy math and I"m just going to call it a very rough estimate, but FX 8350 is 130w part. So 50% more cores, 50% more TDP = 195w.
So perhaps FX 9590 is AMD's way of getting motherboard manufacturers to get ready for a 200w CPU that is actually good.
It would be a marketing win for AMD. They would finally be able to compete on the "high end" with Intel hex core. It would trade blows in multithread with IB-E hex, while being behind in single. So, assuming pricing continues onward I wouldn't be surprised if we saw 6m/12c "entry" level (like 3930k) at around $400 and some sort of extreme edition at $800 or so.
It would look like a fantastic value next to Intel EE and FX 9590 and it would allow AMD to make some good profits on FX chips. People would be price conditioned and AMD could throw in the tin box and shut up the guys who cry about the boxes they're going to throw away on youtube.
I do not know how much something like that would sway people. It would be a nice halo product for AMD even if they didn't sell too many. It'd have a huge advantage over mainstream Intel quads in multi-thread. Perhaps it would finally get some people who go "AMD SUX THEY CANT COMPETE ON THE HIGH END!!!" to shut up.
If they use HDL the die size might not get that much bigger, meaning they could sell it for cheaper while still making a good profit. 3930k die size about 440mm^2, so if AMD could match it in multi-thread with a smaller die, they'd be in really good shape for those who need integer crunching CPUs and multi-thread. Even if AMD brought in 6m Piledriver at 400mm^2 and it tied 3930k in multi-thread and sold at around $400 it would be a really good value for those who need that multi-thread performance.
AMD says 30% die size reduction. Meaning that we'd see 4 module unit at (roughly) 220m^2 and 6 module unit at 330mm^2.
(in case you are wondering about the math, I applied 30% reduction to 315mm die size which gave me 220mm, then multiplied that by 1.5 to simulate adding 50% more cores. Yes I know it's not exact but it's a very rough estimate, I do know I'm not accounting for things).
So realistically AMD could sell this 6m/12c chip for about the same price as FX 8350 goes for right now. Meaning if we got super lucky we could see AMD give us 3930k-like multi-thread for $200.
However I would see them charging more. AMD's margins on a 315mm^2 chip at $200 can not be very good at all. For reference, Intel Haswell Quad with GT2 is about 177mm^2.
Maybe we'd see FX 8000 series replace FX 6000 series and then this 6m/12c chip replace FX 8000?
You really got my mind going Seronx. I had hopes for a Steamroller upgrade, but to be honest, 50% more cores is a heck of a lot better than 20% more IPC and the same amount of cores, at least if you're big on multi-threaded work, which I am.
