Forums - Gaming - PS4, XBOX ONE, which is the more powerful console?

Zappykins said:

Well, there is no question that the PS4 has a more powerful GPU at 1.8 TFlops vs Xbox One with 1.2 TFlops. And the PS4 has faster ram, but that ram also has a higher latency. So we will have to see how that works out. I have a feeling it is also going to be a pain to program for the new PlayStation, all over again.

The big difference I see is something I got from one of the tech talks from Microsoft and Sony's tech spec. It looks like the PS4 CPU's will make one execution per CPU per cycle, while the Xbox One will make 6(!) executions per CPU per cycle. That make the Xbox One's CPU looks significantly more powerful. I am not sure if this is a misunderstanding or some magic they are doing with the cache. But it sounds like the Xbox One might be better in the CPU department.

Then will we have arguing over which is more powerful all over again.

Additional Info: "Some performance numbers were given for the CPU and GPU themselves but these cast more shadow than they do light. Microsoft claimed that each CPU core can perform six operations per cycle. The CPU is believed to be using AMD's Jaguar core, but typically this would only be described as able to handle four operations per cycle; two each of integer and floating point (though even here counting operations is complicated; the floating point operations could use vector instructions such as SSE2, in which case one operation would result in four actual computations, potentially giving eight per cycle for floating point alone)."

Have the leaks of even Sony themselves actually disclosed how many PS4s CPU can do? I think you're misinformed here. Surely NeoGaf would have exploded with this news.

CPU's 2  1 1
CPU Cores 8 8
GPU 1 1
GPU Compute Units 18 12
GPU Stream Processors 1152 768
RAM 5 3
RAM Bandwidth 8192MB @ 176GB per sec 8192MB @ 68.3GB per sec
On Chip Memory 0 32MB @ 102GB per sec


 







 

 

What the hell is this? It's certainly not the PS4 or Xbox One specs.

OK, so besides the miss understanding of the 3 dedicated processors for A/V/N on PS4 what else on this list does not match what has been announced by each company?

Well for starters, the PS4 has 8GB of RAM, you have it at 5......

Xbox one has 8GB of RAM as well, you have it at 3.....

This is getting annoying. You're implying that my whole argument was based on If A Then B; B, => AIt's not. I didn't think I needed to clarify this. I explained in my previous comments exactly how I came to my conclusion and the comment you're obsessing about is only one of the many points that led me to most logical conclusion.

Going by to my previous analogy, further investiation finds that the husband has a history of violent behavior and multiple arrests. 


At least we agree on something, as this is indeed getting annoying, I am not sure we agree on when it got annoying though.

Anyhow, you're assertion was that there mere fact that Microsoft didn't boast of their specs was proof that their console is weaker. 'The mere fact' means that that fact and that fact alone is enough to prove your conclusion. Wich is a logical error as already pointed out. Even if you had brought in all these other references to your argument that you are talking about, your assertion would still be logically invalid and nothing would have changed.

Again, by adding to your analogy you have done nothing to correct the logical error in the reasoning. I have come to the conclusion that you don't understand formal logic, have no intention of applying the rules of logic to your arguments and fail to see the benefit of clear logical reasoning even in informal arguments. It's with a certain degree of sadness I conclude that my efforts over the past two days have yielded zero results and that my dream of this place fostering at least a somewhat rational debate is none the closer.

Thank you for your time.

You're impossible. This is a forum, not a science report. I was right, and you're mad about it. How I came to the the conclusion is obviosuly irrelevant to you. You are obssessed with this notion of the definition of "logic" is. Here's the thing, its irrelevant to the discussion. It's called goal post moving.You can't handle someone bring right so you go on this quest to prove that my comment isn't logical.

If it makes it makes you happy, I'll admit it. I'm not logical. I was right though and I'm sorry if that ruffles your feathers.

That is why I am asking here.  My ears picked it up at the architect conference - 6 executions per cycle?!?  That's crazy.  Ethomaz seems to have found some info that the PS4 can do 4 executions per 2 cycles, so if the space is available it still looks like the X1's CPU is 66% more powerful. 

I guess we shall have to see what they do and what more comes out at E3.



 

Really not sure I see any point of Consol over PC's since Kinect, Wii and other alternative ways to play have been abandoned. 

Top 50 'most fun' game list coming soon!

 

Tell me a funny joke!

You are referring to the GPU with those percentages Tflops - as I point out that exact fact in my post.  Those numbers are confirmed, but not the end of the story.

What I was examine later in my post is the CPU - which are looking more different from each other than alike.  The best I can find (thanks Ethomas) is that the PS4 can execute 2 commands per core per cycle, which Microsoft is restated it's CPU can do six!  So it is looking like the Xbox One's CPUs are 66% more capable than the PS4's. Now Superchuck's excellent thread still has Sony stating 1 execution per cycle.

CPU and GPU are different things.  It's looking like the X1's CPU are more powerful.

I guess we will see more in the next few weeks, maybe.

Thanks for taking the time out from your ongoing fanboy argument to answer my question. ;-P

The CPU's are X86 now.

Even if what you are saying was true....it's not really gonna matter for games.

 

Their both GPU-centric machines now.

That's what the developers wanted, and that's what they got.....basically.

Wait a min, the Arm Cortex A5 is not just some sort of Co-processor, it is a full CPU, and Mark already went over this it handles background downloading.

the Cortex A5 is not just a simple processor or something like that, here look for yourself.

The Cortex-A5 in AMD’s future APUs will be a fully functional ARM processor and in theory it is possible to run full ARM applications on the processor (OS differences not withstanding), though at this point in time AMD hasn’t released the full details on how accessing the ARM processor will work. Even if AMD just intends to use ARM for TrustZone today, this opens the door to comprehensive native ARM code execution in the future if AMD wanted to go that way; but at the same time this could end up being as far as AMD ever goes.

and as its shown there it can be used for more than just security, for instance the PSVita is Powered by a Quad Cortex A9

Cortex-A Series

The ARM Cortex™-A series of applications processors provide an entire range of solutions for devices hosting a rich OS platform and user applications ranging from ultra-low-cost handset through smartphonesmobile computing platforms, digital TV and set-top boxes through enterprise networking, printers and server solutions. The high-performance Cortex-A15, the scalable Cortex-A9, the market-proven Cortex-A8 processor, and the high-efficiency Cortex-A7 and Cortex-A5 processors all share the same architecture and therefore full application compatibility, that includes support for the traditional ARM, Thumb®  and high performance and compact Thumb-2 instruction sets.

The Cortex-A15 and Cortex-A7 both support an extension to the ARMv7A architecture that brings support for large physical address reach and hardware virtualization, as well as AMBA4 ACE coherency. Together, these enable big.LITTLE processing.

http://www.arm.com/products/processors/cortex-a/cortex-a5.php

Its just not a simple coprocessor remember the PSVita is powered by a quad cortex A9, well think the PS4 containing a cortex A5 was not chosen for a reason?

I know what an ARM Cortex chip is.   What I'm telling you is that in its current utilization, it is being used as a co-processor.   You are not usnerstanding the difference in a CPU and a co-processor.   A CPU is the central chip.  Doesn't matter if it's AMD, Intel, ARM, or whatever.   A Co-Processor is a secondary chip that handles tasks that overloaded from the CPU.  This could be another AMD, Intel, ARM or whatever chip.  But that's doesn't make it a second CPU because it is not the central chip.  It is periphery.   Doesn't matter what type of chip is, who made, what other products us it...it is being used a Co-Processor.  This is a matter of terminology and usage.   A CPU is only a "CPU" if it is the 'central processing unit'.   Otherwise, it's just a processor.  Or in this case, a co-processor which supports the operations of the central processing unit.



The rEVOLution is not being televised

RAM- The Xbox One has 8GB of DDR3 RAM, but runs 3 operating systems that take up 3 GB, that leaves only 5GB of RAM reserved for games, the RAM is clocked at 68.3GB/s. The PS4 has 8GB of GDDR3 RAM, and only runs 1 operating system that takes up about 1GB of RAM, that leaves 7GB of RAM reserved for games, the RAM is clocked at 176GB/s.

So in short, PS4's RAM is 2.5x faster, and has an extra 2 GB of RAM to work with.

So technically PS4 has the edge. So what does this mean? More multitasking, yay.

GPU- The Xbox One GPU has 12 compute units and a total of 768 cores with an estimated peak power of 1.23 TFLOPS. The PS4 GPU has 18 compute units with an estimated peak power of 1.84 TFLOPS.

So again the PS4 has the edge.

Yea, it's looking like it was sort of a misunderstanding.  So it's mostly the cashe, latency and memory speed that will effect the changes between the CPUs.

And of course the GPU.
