"Raven Ridge" APUs speculations

So this article made me think:


Raven Ridge APUs will have Vega stream processors and Zen CPU cores. All fine and dandy.
By having this knowledge, and according to the article’s 12 NGCUs, making up 768 stream processors, may we try and roughly guess how fast the APUs will be? Yes we can…

So the Vega stream processors are roughly 20-25% faster than the FuryX stream processors. There are other factors, but roughly 25% faster.
What is absolutely sure, is that the most powerful APU will be more powerful than the RX550, since it will have 768 SPs and the RX550 have 512. It should not be anywhere near RX560 though. The RX560 have 1024 SPs. Yes, the APU will have 20-25% more powerful SPs, but…
The discrete GPU have higher clock speeds and way higher memory speeds. The APUs will still count on the system memory, meaning 2400/2666/2933 etc. So what my guess is, is going to be right in the middle of RX550 and RX560.
For reference, HD7850, R9 270, GTX660, GTX750Ti, GTX950, R9 370 will be all more powerful than the APUs.
A decent comparison can be the RX460. The 460 have 896 SPs with higher clock speed than the APUs most likely will, but the APUs will have faster SPs (stream processors), so most likely the performance will be lying in the RX460 range.

if apus are locked to quads then it could be another reason why intel are finally upping core counts.

I mean, how would intel even be able to compete with integrated that good out of the box?

Upping core count means they (and all other fanboys) can dismiss it as a ‘lowly’ quad core

I get your reasoning but I still think they are going to aim for 7870 level of performance, just so they can claim ‘ps4 level integrated’.

It would be a pretty good marketing win.

RX 560 with it’s 1024 stream processors can’t touch my R9 270X (7870 OC)… The APUs will have less stream processors. I don’t really see how the APUs will have that performance.
Don’t get me wrong, I will gladly replace my 760K/270X with an APU if that means I will not lose performance. But I really doubt that. I mean my 270X is spanking the 1050…

The iGPU seems weak compared to what they could do, CPU side is a massive improvement over 7850K, AMD wants APU users to try out dual gfx. For some reason when you have an APU you really really get curious about it.
I think AMD made most of their money not on Kavari but on the r7 250’s they sold.

Dual gfx is not about fps so much as “hey I actually got it to work!”

As per usual with amd - great amazing technology, that doesn’t quite work as well as it should…
Still it all depends on the performance of the graphics part. Ryzen 3 with RX460 in a single chip with no need for extra power, space, etc… Basically my pc in a single chip…

I am pretty sure this APU if the specs are true is placed above a GTX 750 Ti (probably by a small margin) and an RX 460 is basically tied with an HD 7850/R7 270 and GTX 950 and above a GTX 750 Ti. Don’t know about GTX 660 or R7 370.

Has anyone in this thread actually stopped and considered how good that actually is? An igpu capable of medium high to high settings with a really fast ryzen architecture connected to it? I mean it’s kind of a feat in itself. Think about all the space being saved… All the power delivery being consolidated… And all the super complicated logic that goes into making the architecture seemless

And yet it doesn’t deliver value, because used cards can be bought for less money to give better performance.

Also bundling things means you must upgrade them at the same time, and if you add graphics cards the Igpu does basically nothing (quicksync equivalents being a possibility, but still far from a normal use case).

I read this and thought… Why are we looking at it from a performance and gamers perspective… after all almost all systems built with APU have been HTCP and media center pcs… along with steam streaming boxes

If your just playing media back rather than games or graphically accelerated programs, even intels integrated graphics is fine, so advances in APU’s performance are pretty meaningless, your just worried about how the price stacks up, and used gear will basically always be cheaper.

I am not worried at all… I have a ryzen system and an X99 system i couldnt give a shit less about budget lol … haha thats why I dont fit in this forum… im not here for any budget crap… never have been a budget guy… heck my ryzen system has two 980 Tis lol

however there is a compelling case for APU’s for the people who do care about a certain niche of PC’s or care about a good budget value on a steam streaming box and I can bet you money youll see the difference in performance vs intel igpu… You know how I can bet you that because I even saw the same deal on Llano … gpu to gpu… the amd apu takes the cake and is way better for a streaming // steam stream box… It kind of always has been… Sure i can go out get an i3+rx560 let me do that… oh wait it will probably end up being more expensive … LOL plus overclocking… most people overclock APU’s… what can you not do on an i3 on a budget board to match the price… Well thats overclocking… since intel disallows it on the budget chipsets…

The APU brings flexibility to a world of igpu based intel machines that did not have the UMPH to stream some steam games…

One nice thing about APU’s is you never see them in the troubleshooting thread.
Like deer hunting with a Win 94 30-30, they just work :slight_smile:

This is very true hence…

I mean they simply work on linux… the AMD GPU driver has no problem addressing them… MAC OSX has support for them… they are in every console… etc… they have a place LOL

AMD is phenomenal at finding a place to put something disruptive. APU’s were very disruptive… it took the crowning jewel of nvidia based consoles away… It stole the lime light from intels igpu’s which forced the initial rapid release of quick sync which sucked at first but since matured

If it had no value or place AMD wouldnt make it… they are company seeking to make money… so I mean LOL that argument is kind of moot

Quote: “Vega” graphics core using Infinity Fabric"

Out of curiosity what does intel use communicate with its iGPU?

All that performance, and it boils down to two questions for me.
Can it do Netflix 4K and 4K Blu-ray? Any news/ speculations about that?
So I can retire the Athlon.

Uhmm if a RX 460 + ryzen 3 1200 can at stock then id assume very much yes

Here’s the issue with that…
R9 270 uses a 6 pin power, some models may be dual 6 pins? Let’s say 150W… CPU - lets say 50W so it give us nice round 200W.
Ryzen APU would be about 95W… So half? No space, so you can build ITX…
And seriously, if the pricing is OK, it’s basically Ryzen 3 with RX550 in 1 chip. Poor people build such machines. AMD are giving it to you in 1 chip.
You know old games? Those made more than a couple years back? Metro and Crysis and stuff? Yeah, play that on Intel IGP.

I wouldn’t play games on the Igpu, but I would on a used computer. I’ll make the bet now before pricing and final specs are out that I could get a better gaming experience for the same money (hence mitigate any claims of it targeting poorer people). Also equivalent graphics isn’t necessarily 200w, you could use the 65w of the gtx750ti which is these days a 2 generation old product that still plays modern games at 1080p, so I’d say more under 150w vs 95w. So yes the wattage will still be higher on two devices, but this is not a setup for high duty cycle work like a server or render box, so it really won’t affect the persons annual power bill.

Most mITX system have space for graphics cards, even the cheaper boxes like CM elite 110 support as much. It actually costs more to go with boxes much smaller than that, since you often have to ditch a standard PSU for a specialty one that normally costs more (be it power brick or internal) or not use 3.5" HDDs.

The lower end APU’s are great for OEM’s selling PC’s that are mediocre in terms of upgradability, typically with weak PSU’s and cooling. And APU’s do fairly well in mobile applications where more than intels integrated is desired but the size and heat of dedicated graphics is a problem, so I’m not calling AMD silly for making them. But most of the high end APU’s will be bought by either enthusiasts with another better system or gamers how are getting a raw deal. Those parts (like the older A10) will require fast memory, and will be fun to overclock ect, but don’t economically make much sense to me.

May this be the APU to replace all the old Athlon Pros found in most office pcs?
Most places I know are finally getting their employees a second monitor, and most of their machines are struggling with that in office tasks. I have a feeling AMD is going to make this a compelling upgrade path for companies.

Businesses do not buy used and neither do parents shoping for a new tower for themselfs or their kids.

With Ryzen 5 (thinking 4c/8t or 6c/12t) the upgrade path is really good. When the internal graphics start to show their age, you can just throw in a dedicated GPU and be good for another ~4 years.
