APUs - are they even good?
>>
For basic video playback and shitposting on 4chan yes. Not for gaming
>>
>>52256004
The new Zen APUs are expected to have the graphics capabilities of a 270x. They're also have HBM. So maybe right now they aren't comparable to DGPUs but in time they will take over low/midrange and DGPUs will only be for enthusiasts.

For low-medium 720p gayming? Sure, but that's about it. The best bang for the buck APU right now is the A8-7600 ($80) and anything with better specs does not significantly improve fps (bandwidth starvation).

Also apparently AMD is going balls out with the Zen APUs and will include HBM on the dies or allow motherboard manufacturers to solder on some. We should be getting at least R7 250X performance on an APU soon.

Take it from me, i can play everything on low at 720p
or 800x600 if the game is some trully demanding nvidia gimpworks game.

Im use an A6 3620 non k on 8 gigs of 1600mhz
this is i think the first gen APU, so the 7000 series must be a lot better

everything i play is mostly 45 fps

also cs go and stuff is always 60fps
>>
>>52256221
GPU performance of a R9 270X?
How is that supposed to be possible? Most APUs can barely even keep up with an old 8800GT, so I find that hard to believe.

I have the A10-5757m and i can play mostly anything at 40-60fps at 720p with medium to high settings or 30-40 at 1080 with low to medium settings with 1600mhz RAM. I've seen that there's appreciable increases in performance with faster ram but unfortunately my Acer V5 has 4GB soldered to the board and then an open slot which I've put in 4GB. The ram on the board is only 1600 so nothing i put in the slot will increase speed nor can i lower latencies. :(

Still, i swapped the display with a 1080P IPS panel and its awesome for media, web, light gaming and just a dd laptop.

No need for fast DDR4 when you have HBM on package.
>>
>>52257612
The biggest bottleneck with APUs is slow as balls ram, which is way slower than gddr5, and no matter how many shader cores you added to the APUs, they would never improve. Intel has gone the route of adding eDRAM on the chip, AMD will use HBM.
>>
>>52256004
No. The lack of upgradability kills them.
You can pick up used GPUs with 2x the power for less than the APU premium.

>>52256004
Wait for Zen if you plan on getting one.

While we're on the topic of AMD stuff, why do certain processors that I'm seeing on pcpartpicker have more cores and higher clock speed, but perform worse?

Also, I'm considering doing a server motherboard with multiple CPUs for gaymen. Is this a good idea or am I retarded?
>>
>>52260131
Because AMD's instructions-per-cycle is ass so they need to run their CPUs at ridiculous clock speeds out of the box.
Also a dual-CPU motherboard for gaymen is completely unnecessary.
>>
>>52260222
>Also a dual-CPU motherboard for gaymen is completely unnecessary.
Thanks m8. Someone suggested that to me and I thought it was a good idea for some reason.

>Because AMD's instructions-per-cycle is ass so they need to run their CPUs at ridiculous clock speeds out of the box.
That's a shame. I want to stick with AMD since Intel backdoor memes, and AMD is pushing for open source more than Intel is.
>>
>>52260305
They just focused on the wrong things with Bulldozer/Piledriver. They're great CPUs if you're doing multithreaded work and don't want to shell out the cash for an i7, but most games aren't optimized too well for more than 4 cores.

My phone can run that, realistically you'd want to aim for 720/1080(1080 is pushing it) @ 60 to not cause damage to your eyes. From one anon to another though, it's not worth it just yet to get apus, not even zen can bring that power just yet.
>>
>>52260404
This is still completely false no matter how many times you regurgitate it.
>>
>>52256378
7870k is very capable
you MUST buy fast ram and a board that supports that speed, the max speed of ram that an apu can support is 2400mhz
https://www.youtube.com/watch?v=Cv57qDXpEPU
>>
>>52260525
>the max speed of ram that an apu can support is 2400mhz

This is only the max speed that DIMMs will boot to by default. If you manually set your RAM to 3000mhz, assuming you had a capable kit, the APU/board will handle it just fine.
>>
>>52256142
My a10-6800k and it's integrated video + 8gb ram play borderlands 2 at max settings 1080p 40-60fps, gta 5 medium settings 8x multisampling 1280x720 at playable 30-50fps. Pretty good for $70 apu.
Where is your god now, Moishe?

Guys, I'm scared. Intel's integrated graphics seem to be catching up with the APUs. I'm still buying the next APU laptop when it's upgrade time, but lately I worry that AMD will go under because of intel beating them at their own game...
>>
>>52260589
Meh, we'll see what happens when Zen drops. HBM APUs and such.
>>
>>52260587
Forgot to add that it fits in a very small mini-itx case with a 100watt pico-psu.
>>
>>52260589
AMD's IGPs still have more raw compute power, they're just heavily bandwidth limited. intel has a superior memory controller, superior cache structure, cache cells too for that matter, and their high end Iris Pro chips are using a big slab of high speed eDRAM to feed the IGP with adequate bandwidth.

The 8CU in Kaveri/Godavari would outperform intel's Iris Pro chips if you could give it fast enough memory. Their future Raven Ridge APUs have HBM on package, and the IGP is significantly larger as well, so intel will once again be very far behind in IGP performance.
>>
>>52260587
Really? got sauce?
>>
>>52256004
>>52256142

They're fine for light gaming, as in Doter, Legal Legends or even CSGO and some older AAA <2012/2013 run fairly well, or at least ok. Well, you can also reduce resolutions to 720p and actually crank some details up.

>>52256378
Don't fall for the A10 meme. See >>52256998 , albeit you can play some less demanding (online) games at 1080p easily.

>>52257612
It could work with some on-die HBM memory. The PS4 iGPU isn't far from a 270X in performance. :^)

>>52259376
>>>/v/

>>52260589
Zen and HBM might take things a notch up.
>>
>>52260789
Forgot to add - if the RAM speed suffices, of course. Get at least two 1600 sticks in dual-channel, better 1866 or 2133. Timing doesn't matter as much, you need raw bandwidth.
>>
>>52260789
>Zen and HBM might take things a notch up.
No, it's going to rape intel. That a8 apu is already shitting all over the skylake igpus and the only competition it has is the igpu on the broadwell processors (which intel stopped making).

640-768 gcn cores with 128gb/s hbm is going to fuck intel's shit up so hard they'll have to give most of their income to companies to encourage games devs to run games on a single thread more than ever to stay relevant. Zen won't have the same ipc as skylake or kabby lake but it will sure have a batshit crazy powerful iGPU.

Interesting times are ahead of us. intel has had it easy for too long.
>>
>>52261105
>640-768 gcn cores

Its going to be bigger than that, likely 14CU or more. 20CU moderately clocked would only have a slight memory bottleneck with 1 HBM module, and there is no technical hurdle in featuring an IGP this size. AMD did it for Sony with the PS4 and its operating inside of a 100w envelope as a 28nm part.
14nm Raven Ridge with 4 Zen cores with 20CU could easily fit within 150mm2. They'll totally lock down mobile graphics, prebuilts, and all in ones. Nothing they've ever done has had this much of a competitive lead.
>>
>>52261191
I want to believe, but in all likelyhood even if AMD knocks it out of the park and has products that smash Intel at every price point Intel will pull its old dirty tricks and force their stuff on the market. They'll pay a few billion down the road to AMD so they barely stay afloat but in the mean time AMD will have lost years worth of R&D that could have helped them compete.

The only hope for the x86 market is for Intel to be broken up into separate companies. Chip design, chip fab, and x86 licensing.
>>
Zen will shit all over anything Intel has in homogenous computing
>>
>>52256004
Best value is an a8 7600. Get it and overclock the fsb, then overclock the gpu.
Idk about prices where you are but it's 40-50 dollars cheaper than an i3 here and should be good enough for light gaming. Battlefield 4 1080p 40+ frames per second on medium, or turn it down to low for even better performance.
>>
>>52261468
>Intel will pull its old dirty tricks
You mean how they purposely gimped programs compiled with their compiler on every processor that wasn't an intel, so they could claim stuff ran better when it was them selling snake oil?
>>
>>52261468
Intel can bribe the shit out of OEMs, but as far as OEMs are concerned what matters most is profit. If a certain product appeals well enough to consumers that its going to fly off shelves then intel wouldn't be able to pay them enough to keep it out of market.
>>
>>52262655
OEMs will be really interested in Zen especially the laptop APUs. They could chuck together a "gaymen" laptop and sell it for mad dosh. This would greatly improve battery life and give users an iGPU that could run even the most recent games on low 1080p settings.

This could be it fellas, the desktop might soon be on suicide watch.
>>
>>52262804
intel mobile IGPs would be left out in the cold
all mid range MXM cards would be irrelevant
only high end mobile GPUs could compete

A 35w Quad core with an IGP out performing a GTX 750ti is completely possible.
>>
>>52262849
OEMs won't even use a 35w carrizo, why should this be any different?
>>
>>52263045
Massive uplift in CPU performance and an IGP that shits all over the super expensive Iris Pro while consuming less power.
>>
>>52263045
Bruh, Zen will have 40% ipc over carrizo (aka excavator) and Zen will be on 14nm lithography. This means that a 2.7 GHz quad core Zen chip will have the juice of a ~3.6 GHz quad core carrizo. So the lower clock speed, use of 14nm lithography, and overall better power efficiency means a quad core 2.7GHz zen with a 12CU could have a TDP of around 25 watts.

Battery tech is also improving.
>>
>>52263229 >>52263080

I want to believe, but I doubt OEMs would be so kind to AMD.
They don't see the APU as an APU, but as a processor with an igpu, just like Intel. Carrizo had the chance but they fucked it up by limiting it to 15w.
I would love to buy a zen apu hybrid cfx laptop since it'll be amazing value for performance, but if zen isn't designed to be 15w then it's just going to cripple it, just like they did carrizo.
>>
>>52256366
Congrats that's called a toaster barely being able to play a game.
>>
>>52263703
I see what you mean. Yeah the 15w tdp limit is dogshit even for zen. OEMs could remove that restriction if they removed the optical drive and gave the extra space for another battery or a larger existing one.

I mean the 15w tdp only exists because battery life is dogshit if the cpu has a higher tdp. The solution is there but I'm not sure if OENs are ready to scrap the optical drive for good.
>>
>>52264066
>I mean the 15w tdp only exists because battery life is dogshit

Its actually a matter of form factor. A 15w chip needs a much smaller thermal solution. AMD's big problem is still most vendors putting their chips in bottom of the barrel systems with stupid single channel memory configurations.

Why do normies want paper thin laptops so much? We could have had extremely powerful laptops but the "muh thinness" meme fucking ruined all of it.
