AMD AM4 is another PGA socket?!

[Mr.Scott]

It wouldn't need to be as big as it was since cache is on CPU die now. And for space saving purposes, it should be installed down like how M.2 is installed.

It will be difficult to mount cooling. Especially the big heavy air coolers.

Personally, I think CPU aftermarket coolers are going overboard with insanely big coolers. CPU is becoming more and more power efficient but coolers are becoming only bigger. Remember how small CPU coolers were?

It's only a gimmick.

Xeon Phi, anyone?
Would've been a lot more fun to make a hypothetical future motherboard with only a chipset, super I/O and a shitload of PCI-e 4.0 slots.
Wanna have a bad-ass machine? Simply plug in another card with a bi-centi-core CPU and 64GB HBM2.0 in addition to the one you have!

Voted PGA only because mainstream slotted CPUs ain't going to happen...

I don't have any problem with the size of CPU coolers as long as they are fanless/silent.

I'm currently using my Thermalright Macho cooler without it's fan thanks to a little undervolting and underclocking.

Let's be honest they cannot even design a power efficient GPU anymore unless they have access to newer semiconductor fabrication technology and the example is the RX 480 which while it has an improved power efficiency cannot even beat Nvidia's last generation GTX 970/980s. It's ridiculous to see while Nvidia is doing well with GTX 1070/1080 AMD release RX 480 which optimistically can match last generation Nvidia cards in both power consumption and performance.

And yes Nvidia did rebranding too but that was a while ago I'm talking about the present. after a really bad experience with power hungry 290x and Sapphire Toxic 280x which died last week I'm more than happy to get back to Nvidia.

Awhile ago?, peh, gf 900 series.

Mine runs at ~300-700rpm and noise isn't an issue at all. I hope that it stays also quiet when I'm upgrading to Kaby Lake.

I believe it will stay quiet. I'm more worried about PSU fan noise that nothing can be done about it. As soon as I run games my PSU fan makes enough noise that it doesn't really matter the rest of the components are quiet or not.

Which PSU do you have? Nothing in your System Specs is listed.

It's an Antec HCG 520.

I believe the LGA has better contact due to gold-plated copper

Mine has a horrible coil whine, but I guess I need to change my PSU anyway since this old Corsair probably won't be powerful enough for a 780Ti SLI.. In desktop or not so GPU-intensive gaming (like CS:GO) it stays quiet.

AFAIK AMD's pins are also gold-plated copper.

So you want to run two GTX 780s in SLI. Do you think it really worth it?

And by the way there are ways to cope with coil whine.

They're cheap, bought mine 170eur including shipping some time ago, and 3GB VRAM isn't a problem for me. And I was going to upgrade my PSU anyway, so no problem there also.

 

[Ubersonic]

Hell, bring back the slot. If you fuck that up, you're worse than me and should be banned from computers forever.

I knew somebody who fried a motherboard and CPU by putting a Slot-A Athlon into a Pentium II/III Slot 1 board

Be careful buying those used cards.


I was telling the same to myself that they are cheap. My 290x and 280x only worked 2 weeks before dying.

You can see they look OK and nothing seems bad about them but then suddenly...

I've owned probably over 100 graphics cards, and I've bought about 5 of them as new. Also the count of dead cards is something similar. So I'm not afraid to buy used cards even without warranty, like this 780Ti which I have now.

Well, that's possible because they're mechanically identical, just flipped by 180 degrees.

Yeah, you would have thought having to remove the heatsink to get the chip onto the board would have been a warning sign but no he figured it would be okay to test the system and he would get a HS that fit later >.>

Probably ran into bad luck with a batch of bitcoin mining cards.

I'd say most of those have been sold and died by now. If you were to buy used in the future, I'd expect much better luck.

 

[Ensefalon]

I've been thinking about disadvantages of PGA sockets as every time I try to uninstall my CPU cooler the CPU itself gets out of the socket. Also there's a possibility to bend CPU pins.

I believe LGA sockets are no more expensive than PGAs but now another PGA socket for AMD's new platform is something I don't really understand!

There is risk with every kind of socket...AMD makes chips with stupidly high TDPs and they make their pins more burly to handle the current...but universally it means you don't have to get a new motherboard to support the higher tdps...learn how a processor VRM works...you'd be amazed

I've seen so many posts about bad 280X's even I am scared of them, bitcoin mined or not.

 

[Mussels]

we need PGA, but like intel with the metal clip on shield over the top to prevent your CPU from pulling out too early (this is only effective as a contraceptive, not as a CPU removal technique)

What does it have to do with VRMs? They are simple buck converters with a controller but I don't think the type of CPU socket is that much related to VRMs as both PGA and LGA can handle enough current.

PGA can be/is ruggedized...Due to the actual shafts the pin enter allowing for much lesser points of resistance due to a much larger surface area of contact. Voltage drops, vrms handle. The ruggedization part comes from that amd puts stupid diffirences in TDP of all their processors...But the pin material change and the socket doesn't allowing you to use lets say an FX8350 or something like that without having to get an entirely different socket completely to handle the higher tdp

EDIT: Its what saves manufacturing time and a majority of lesser painful redesigns

I've been a PGA fan since the 386 (PGA 136) days you know the ones where you had a x86 cpu in a socket and if you wanted to do math fast you bought the FPU to plug into the other socket or bought a much more expensive 386 (non SX model) the SX for sure stood for sux xtra badly but the DX models well now they had it all built in FPU and 20MHz bus but I digress

I've seen some right horror stories regard bent pins in the socket with LGA and it's so much easier to straighten a bent PGA pin I have an old Phenom II x4 940BE that was given to me with about 20 bent pins gently straightened them up and it's still running to this day 7 years later like nothing was ever wrong with it

 

[dorsetknob]

got the matching pair in my CPU collection
386 Sx 20Mhz and the 20Mhz 387 FPU chip Pic used to be in nostalgic Hardware thread ( think links broken )

Funny how a Credit Card is just the Right thickness to slide between the pins to aid Straighten them out and if that fails you can use it to buy a replacement
