AMD CPU under 100$

[DrMrLordX]

Good point! I have ordered 860k and i pretty sure i wont be dissapointed because it totaly worth 85$

Then may it work well for you. They're good chips for the price. If you need any help overclocking it or undervolting it or whatever it is you plan to do with the thing, just ask around, and the small number of Kaveri users around here should be willing to help you get the most out of that chip.

So when will we start seeing these new FX-83xx on these new wafers? You've peaked my interest.Or is this something your making up or guessing at? seeing how cheap FX stuff is right now I think I would snag one of those new wafer FX-83xx's up in a heart beat just for something to do to hold me over till Skylake or Zen comes into play.

Well, you can get at least three of them right now: the 8320E, the 8370E, or (if you really want one) a 9590 with a manufacturing date of wk29 2014 or later.

I guess the 8370 is coming from newer wafers too, though it hasn't been binned for low current leakage characteristics as the 8320E and 8370E have (or high current-leakage as is the case with the 9590).

Anything else and your guess is as good as mine. You should not expect chips that do much better than the E chips or the 8370, though, even if AMD does move different stock into the supply chain that come from the newer wafers.

So, if we see "new" 8320s and 8350s, my guess is, they'll be about as strong as the 8370. What I was sort of hoping for was something like a FX-63xxE, which would probably have had a sub-95W TDP, and probably would have been good for 4.7-4.8 ghz at the same power draw you see with 4.4-4.5 ghz 8320Es today. A lot of people would have liked that. It's too late in the FX lifecycle for that though.

Cost of ownership can be slightly lower once you factor in other things, like boards and power draw.

Here is an AM3+ 760G board with 125 watt CPU support and third party usb 3.0 for $44.99 AR plus $1.99 shipping:

http://www.newegg.com/Product/Product.aspx?Item=N82E16813128565

So board price difference is not much (although SATA 6 Gbps is missing on the low end AM3+)

I haven't investigated idle power differences between AM3+ And FM2+ yet.

 

[DrMrLordX]

I wouldn't recommend a 760G board, sorry. 970 is the lowest I'd go, and he had a pretty good 970 board picked out anyway.

If you want to blow the VRMs sure. And why is Gigabyte still selling a mobo from 2007 in 2015?

What are your reasons for that?

It is a revision 6.0 with 4 + 1 phase with a heatsink on it.

...And I only saw one complaint of failed VRMs.

 

[DrMrLordX]

What are your reasons for that?

Okay. It's feature-poor, the chipset is ancient, and it's a 4+1 configuration. I've seen some 4+1 boards out there where it might be fun to risk a 4.0-4.5 ghz OC with one an 8320, but I'm certainly not going to recommend that to someone else, especially not given the other problems inherent to the board.

Besides, OP got an 860k which is just fine and dandy for him. No need to worry about VRM configurations or any of that nonsense. It's not like he's trying for 4.7 ghz.

Hey, Magnus
What would you think about an A10 7850K rig?
I built one last year but it has not been in use at all. I had big plans of making a HTPC out of it, but at the same time I built it our old Samsung TV broke and we got one of those Smart Tvs with Netflix and all so we have been using that.
I dont know how that CPU scores compared to the other parts you listed and I am not sure if it is overclockable even. I dont know if this is against forum rules or not but you can have it for 2000kr w/o shipping, then you will have 3000kr for graphics. I Have to say that it is a mini PC but you should be able to get a graphics card in there. I live in Oslo.

The build is as follows

AMD A10-7850K Black Edition
Socket-FM2+, Quad Core, 3.7GHz, 4MB, 95W, 28nm, Ra

Corsair Vengeance DDR3 1600MHz 4GB CL9
Kit w/2x 2GB XMS3 modules, CL9-9-9-24, 1.5V, Lav V

Gigabyte GA-F2A88XN-WIFI, Socket-FM2+
mini-ITX, A88X, DDR3, 1xPCIe-x16, DVI, 2xHDMI, DP,

Silverstone SST-ST45SF-G 450W PSU
SFX, 80 Plus Gold, Standard, 1x 6+2pin PCIe, 1x 6p

Vifter: 1x 120mm Front, Support SFX PSU, 2x USB 3.

Logitech Wireless Touch Keyboard K400
For wireless control of your laptop?even when it's.

Also consider that nobody who is suggesting an 8320E in this thread recommends leaving it at stock! The reason to get that thing is to overclock it. 4.3 ghz on an 8320E is going to be pretty easy in most cases. As I've mentioned, the stock cooler and the board the OP mentioned should get him there.

But if all he cares about are 2-4 thread applications and he wants an AMD chip for that, the 860k is actually his best bet. And it's cheap, too.

Besides, it would almost be a shame leaving that 860K at stock, right?

From what I've seen, they should do 4.2-4.3GHz on the stock cooler easily...

If i3s are that good, why doesn't anyone here actually recommend their use?

i3's are fine chips. In my opinion they just occupy a slightly though spot on desktops. Basic i5's are not that much more expensive, and provide a lot more MT performance.

Personally, if I didn't require gaming I could get by just fine on an i3-4370 (3.8GHz), or if I really needed the i5 features a 4570T (i3, with turbo @ 35W... ).

Okay. It's feature-poor, the chipset is ancient, and it's a 4+1 configuration. I've seen some 4+1 boards out there where it might be fun to risk a 4.0-4.5 ghz OC with one an 8320, but I'm certainly not going to recommend that to someone else, especially not given the other problems inherent to the board.

Totally agree, why anyone would recommend a mainboard based on a 2009 chipset is completely beyond me...

Hey, Magnus

Welcome to the forums...

There would be little need to get a 7850K since the OP will be using a discrete graphics card. 860K = 7850K without the integrated graphics.

 

[cbn]

It's feature-poor

The features on that $45 AR AM3+ board are better than my own FM2+ board: Gigabyte F2A58M-DS2

Now, the A68 boards add usb 3.0 and two SATA 6 gbps, but still have two less SATA ports than that $45 AM3+ board

the chipset is ancient

How is the chipset being older specifically a detriment though?

About the only thing I can think of is that Gigabyte (and other motherboard makers I looked at) did not list Windows 8.1 drivers for this older AM3+ chipset. However, it looks like the Omega driver has that covered--> http://support.amd.com/en-us/download/chipset?os=Windows 8.1 - 64

and it's a 4+1 configuration. I've seen some 4+1 boards out there where it might be fun to risk a 4.0-4.5 ghz OC with one an 8320, but I'm certainly not going to recommend that to someone else, especially not given the other problems inherent to the board.

4 +1 (with heatsink) should be fine for OCing FX-6300. In fact, One newegg reviewer on 2/25/2015 reported 4.7 Ghz on a FX-6300.

P.S. As far as octocores go, the board supports FX-8350 (which is already 4.0 Ghz base @ stock). Another Newegg reviewer on 2/16/2013 reported FX-8150 stable at 4.4 Ghz.

Besides, OP got an 860k which is just fine and dandy for him. No need to worry about VRM configurations or any of that nonsense. It's not like he's trying for 4.7 ghz.

My Gigabyte F2A58M-DS2 can't overclock my Athlon x4 860K, and I imagine this is also the same for some A68 boards. So budget board selection still does matter for FM2+.

Its cheap, better than my own FM2+ board, and it overclocks a FX-6300 well?

 

[ogbbv]

Hey thanks for the welcome Insert_Nickname. I also saw much too late that he allready have bought a CPU. just thought I would post to help a person with a budget out and since I dont use mine mine would be a steal for what I gave for it and within his budget with case, ram and all.

 

[Insert_Nickname]

If you could look past the lowest-end A55/58 boards, you may be surprised. Its not like A68/78-boards cost a fortune more then the A55/A58s. F.x. that Asus A78M-A I've mentioned is a pretty decent board, while not being terribly expensive. Built a couple of systems around it myself, so I should know.

As for overclocking, its a dice throw. You can never be certain of what you're getting.

The 7850K is a good chip, no question. Especially with the recent price cuts.

However, for pure performance, if the budget is large enough one should really look at a 750K/860K (or G3258, if ST performance is required) and something like a 250X/750non-TI. Those cards have way greater performance then any APU. What's more you can save a few $, since dual channel memory is not really necessary when not using the IGP. You can also use cheaper memory with more relaxed timings.

My point is really, as I stated in a previous post, that when on a budget one has to take a more holistic approach, because there will always be trade-offs...

BTW, its not like I care about a specific manufacturer. I go were I get the most for my money. Perhaps even more important, I go were I get what fits my requirements.

What I was sort of hoping for was something like a FX-63xxE, which would probably have had a sub-95W TDP, and probably would have been good for 4.7-4.8 ghz at the same power draw you see with 4.4-4.5 ghz 8320Es today. A lot of people would have liked that. It's too late in the FX lifecycle for that though.

Ok thanks but I will pass. I took that new wafer as a meaning a die shrink and possibly a lower tdp for higher clocks. Oh well one can wish right??

That's an FM2 board in FM2+ clothing. Don't look seriously at anything unless it's A85x or A88x (nor should the OP). If you get it for free, maybe . . .

How is the chipset being older specifically a detriment though?

It means someone's dumping old inventory, whether it's old components or just flat-out old boards. Those ICs were not designed to handle Bulldozer or Piledriver, and the VRMs and other board components certainly weren't either. If it actually works AND you manage to OC on it, then you're lucky.

The OP was already looking at the MSI 970 Gaming, which is one of the new 970 rehash boards that has some people giving MSI another look for AM3+. So far, so good. The price is right and it's a 6+2 board. Provided it doesn't go through the magic popping VRM problems that some of the older MSI AM3+ boards went through, I think he would have rather liked the board, provided he had gotten a 6300 or 8320E. I think the 8320E (which is the only FX he should seriously have been considering) would have done rather poorly on that 760G board. He would have been limited to lower clockspeeds at the best.

4 +1 (with heatsink) should be fine for OCing FX-6300. In fact, One newegg reviewer on 2/25/2015 reported 4.7 Ghz on a FX-6300.

. . . and it would have limited clocks on an 8320E. I expect that most 6300 owners would have some problems with this board as well. That board has ICs as old as my GD70 (a 4+1 790FX board) that scarcely even supported Thuban, much less Piledriver. Good grief.

P.S. As far as octocores go, the board supports FX-8350 (which is already 4.0 Ghz base @ stock). Another Newegg reviewer on 2/16/2013 reported FX-8150 stable at 4.4 Ghz.

Then I'm just going to chalk that up to risk-takers getting some good luck with an old chipset. There's still no reason to buy anything that old, with such lackluster features, and 4+1 power phase to boot, when you can get something that makes sense at a price that fit into the OP's budget.

My Gigabyte F2A58M-DS2 can't overclock my Athlon x4 860K, and I imagine this is also the same for some A68 boards. So budget board selection still does matter for FM2+.

. . . and that's what you get for not buying A85x or A88x?

Ok thanks but I will pass. I took that new wafer as a meaning a die shrink and possibly a lower tdp for higher clocks. Oh well one can wish right??

Yeah, one can wish. I do not think we'll see die-shrunk Vishera. We probably wouldn't like what we saw if they did put Vishera on 28nm planar.

 

[cbn]

As for overclocking, its a dice throw. You can never be certain of what you're getting.

The Fm2+ A58 board I have doesn't allow adjustment of the Vcore.

And so I am thinking some of the other basic A68 motherboards could be limited in this respect also.

 

[cbn]

Those ICs were not designed to handle Bulldozer or Piledriver, and the VRMs and other board components certainly weren't either. If it actually works AND you manage to OC on it, then you're lucky.

AMD approved the chipset for use with Bulldozer and Piledriver.

Furthermore, if the TDP of the AM3+ processor is the same as the AM3 processors is that really a problem? In fact, I only saw one complaint of failed VRMs in 273 Newegg reviews for that board.

 

[cbn]

There's still no reason to buy anything that old, with such lackluster features, and 4+1 power phase to boot, when you can get something that makes sense at a price that fit into the OP's budget.

FM2+ doesn't have a hexcore though.

And while the Athlon x4 860K has slightly better IPC than FX-6300 , it doesn't overclock past 4.5 Ghz (except for the top boards) and it will also suffer from more module penalty than the hexcore Vishera. Furthemore, Vishera does have L3 cache (although I don't it adds much to gaming performance)

P.S. Regarding 4 +1 VRM phases, I think that kind of power delivery (with heatsink) should be sufficient for overclocking FX-6300. If wanting a 970 board then the ~ $60 Biostar TA 970 (4 +1 VRM phase with heatsink) is another low cost choice. MSI 970 Gaming does have 6 + 2 phase, but I don't think that is really needed for OCing hexcore and adding an octocore to that board pushes the budget past $200 (for CPU + mobo).

 

[DrMrLordX]

AMD approved the chipset for use with Bulldozer and Piledriver.

So that means they figured out how to BIOS-hax the thing and get it to support Visheras. Great! That ranks up there with running Phenoms on AM2 boards. Fine for people that already had boards, but not the brightest option in the world for a new buyer.

Furthermore, if the TDP of the AM3+ processor is the same as the AM3 processors is that really a problem? In fact, I only saw one complaint of failed VRMs in 273 Newegg reviews for that board.

NewEgg complaints are hardly representative of potential problems with the product. How many of those reviewers were trying to run an FX-8350 on there or something like that? There were plenty of AM3 boards - allegedly good ones - that would go nuclear trying to overclock Thuban, for crying out loud. 760G wasn't even that good of a chipset.

FM2+ doesn't have a hexcore though.

He didn't specify that for his use-case.

And while the Athlon x4 860K has slightly better IPC than FX-6300 , it doesn't overclock past 4.5 Ghz (except for the top boards) and it will also suffer from more module penalty than the hexcore Vishera. Furthemore, Vishera does have L3 cache (although I don't it adds much to gaming performance)

Kaveri has no "module penalty". And it doesn't seem to be bothered by the absence of L3.

P.S. Regarding 4 +1 VRM phases, I think that kind of power delivery (with heatsink) should be sufficient for overclocking FX-6300. If wanting a 970 board then the ~ $60 Biostar TA 970 (4 +1 VRM phase with heatsink) is another low cost choice. MSI 970 Gaming does have 6 + 2 phase, but I don't think that is really needed for OCing hexcore and adding an octocore to that board pushes the budget past $200 (for CPU + mobo).

There are plenty of 4+1 boards that fail at overclocking an FX-6300. Regardless, if he really wanted an FX, I think he should have picked up the GA-970-UD3P and an 8320E, but guess what? He saved some money and got an 860k which will do him just fine. He can grab an A88x-Plus for less than he would have paid for the MSI 970 Gaming, too, and he can use the stock cooler in relative comfort.

Can you give an example of why running AM3+ on a AM3 chipset is such a bad thing? If AMD designed the processor to be backward compatible then I don't see why doing so should be avoided.

There are plenty of 4+1 boards that fail at overclocking an FX-6300.

What boards are you referring to?

I haven't done much investigation on the vanilla boards, but if they support 125 processors then they should be able to do at least *some* overclocking of a 95 watt processor.

P.S. Not all 125 watt 4 + 1 boards have a heatsink on the VRMs. The 760G I linked did (and so did the Biostar TA970).

 

[cbn]

How many of those reviewers were trying to run an FX-8350 on there or something like that?

Not all the reviewers listed their processors, but there were several using FX-8350. A few were using FX-8320, One had a FX-8120, one had a FX-8150 (overclocked to 4.4 Ghz), two Thuban were listed (one overclocked to 3.5 Ghz and the other @ 4.01 Ghz)

P.S. There was one claim of a stock FX-6300 throttling under Prime 95, but that could have been related to some other issue not related to the motherboard (ie, improper mounting of heatsink).

 

[DrMrLordX]

Nevermind. If you want to push a $44 760G motherboard in a thread where the OP picked a different platform entirely, you go right ahead. Case stated, I'm out.

 

[Insert_Nickname]

The Fm2+ A58 board I have doesn't allow adjustment of the Vcore.

And so I am thinking some of the other basic A68 motherboards could be limited in this respect also.

They're budget boards. What are you expecting? 5.0GHz 860K on air? What's more I think that its more of a manufacturer decision to limit Vcore adjustment*, rather then a chipset limitation.

* Likely done to prevent people from frying the sub-par power delivery circuitry with extreme overclocking, and then complaining about it online.

 

[TeknoBug]

My Gigabyte 970A-D3 with 4+1 and heatsink didn't play nice with OC'ing a X6 1090T, FX 8320, 8320E but OC'ed a FX 4350 easily to 4.7GHz. Overclocking with 4+1 can boil the VRM.
