AMD CPU speculation... and expert conjecture
We have had several requests for a sticky on AMD's yet to be released Steamroller architecture ... so here it is.

I want to make a few things clear though.

Post a question relevant to the topic, or information about the topic, or it will be deleted.

Post any negative personal comments about another user ... and they will be deleted.

Post flame baiting comments about the blue, red and green team and they will be deleted.

Our previous sticky concerning Piledriver can be found here:

Enjoy ...

When a GPU is so much more powerful then the Xbox one that won't happen, however there is times where the xbox one comes out ahead if you watch FPS videos comparing both.

Wow. Are we gonna spend pages talking about how generic x86 binaries on a software platform designed to run on a lot of different types of hardware is proof that Jaguar is slow in an environment tailored to the hardware?

You might as well let me throw out optimized Gentoo benchmarks where I beat 3930k and then start saying FX 8350 is faster than 3930k.

Also, some of you are way out of touch. When someone has to lower resolution and graphics settings, like in Watch Dogs, it's not because of CPU. In fact, you'd see consoles hitting 1080p/60fps no problems if the GPU wasn't the bottleneck, because scaling resolution upwards shifts the bottleneck further from CPU and more toward GPU.

If CPU was the problem, we'd be looking at big empty games with no AI and stuff going on but they'd be 1080p/60fps games.

Unless someone wants to show me a situation where CPU was the bottleneck and it ended up with resolution being dropped.

Technically we're CPU-bound," he said. "The GPUs are really powerful, obviously the graphics look pretty good, but it's the CPU [that] has to process the AI, the number of NPCs we have on screen, all these systems running in parallel.

"We were quickly bottlenecked by that and it was a bit frustrating, because we thought that this was going to be a tenfold improvement over everything AI-wise, and we realised it was going to be pretty hard. It's not the number of polygons that affect the framerate. We could be running at 100fps if it was just graphics, but because of AI, we're still limited to 30 frames per second."


Now on the statement about a CPU has nothing to do with high res gaming then why don't we all just get Intel Atom CPU's in are gaming rigs and game at 1080P with a 980?

No, CPU has nothing to do with resolution. It can limit FPS, but resolution depends only on GPU and/or memory.


Then please explain how a 7870 can't provide 1080P gameplay when it can on the PC?

if you would have ever tried any mmo's or online competitive game you would think the same

i still don't get it why console devs wants it to be either 60fps or 30fps, 50fps/1080p would be a reasonable compromise.

also, you folks are aware that these consoles are running vsync right? i believe that puts a significant strain on that 7870 that runs on the ps4.

Well, Jaguar being a bottleneck or not will depend on how they designed the CPU component. I don't know if they're running a full X86 ISA for the custom designs, so you can squeeze more performance out of it than the general purpose CPU we get for desktops. Remember it is still a custom design from MS and Sony.

Now, Devs using previous gen Frameworks and tools is also another BIG factor to the current "stall" in games. It's not even an "adaptation" thing, but a "Publishers are being cheap bastards". Well, they've always been, but there's a weird thing going on for MS here as well. If devs switch tools and all, maybe games in Windows will be even better than in the consoles (not that it isn't true now though) and as such, they'll cannibalize their own console market.

It is a very weird position that MS has put themselves in.

Cheers!

Jaguars aren't really weak for what it needs to do. I doubt there is even a point in sticking in more powerful cpus in console which have the main purpose of running games. Games really aren't being CPU contained these days as they once were for the console environment. Pretty much any cpu seems to run games at 30 - 60 fps which is what they do in the consoles. The GPUs however are where the silicon and power budget is spent.

If the consoles didn't need 2 cores of overhead to make sure the RTOS to run background apps, they would have been fine with a 4 core jaguar. Then they could be designed with more GPU resources.


Dev's would disagree with you

Dev's always want more power, they aren't the ones designing the console to be affordable and balanced.

Also you need to back up that argument by giving some quotes about how the CPUs is weak compared to the GPUs in the new consoles in a game environment that doesn't involve any emulation. I would love to see some quotes of this.

This is just one case and then we can conclude a 7870 would be bottlenecked by even a Phenom II X6(without optimization) let alone a 8 core atom CPU or jaguar. I understand in consoles they can make up for it but its still their the weakpoint isn't the GPU. A 7870 is strong enough to do any PC game so far at 1080P medium yet consoles still lack that feature. Its almost common since, there is a bottleneck and i'm putting my beats on the CPU since the GDDR5 memory on the PS4 is more then adequate for 1080P gaming.

Basically when i see consoles do 1080P as a standard and not a special thing i will then conclude that the CPU isn't the bottleneck since a 7870 can do any PC game at 1080P medium settings. It would even be different if the games were 720P 60FPS buts it not.

That doesn't say anything in regards to what I said.



I think its already established that the CPU is to weak for 1080P gaming in a gaming environment since everything else can be ruled out for the PS4 over the GPU being capable of 1080P. At least with the Xbox one we can conclude the low memory bandwidth is holding it back but with the PS4 and its GDDR5 memory and 7870 like GPU all games should be playable at 1080P since it would be on the PC with an adequate CPU.

Edit, i'm not to sure i understand what you mean by emulation you mean playable PS3 games or PS2 games on the PS4, if so that's not what i mean.
