PlayStation 4 to be revealed February 2013?

Isn't it shared? The system could use 1-2GB and that will still leave the GPU with 6+.

 

While it's shared, consoles run minimalist operating systems, so nearly all of that will be available to the GPU.

 

Is it? I didn't watch the whole presentation. Normally it's the other way around though, and the rumors have been that the GPU is the equivalent to a HD 7670 with 1GB RAM. The PS3 is split between 256 MB main and 256 MB VRAM.

 

They won't be using a 7GB system, 1GB GPU setup, at worst I would expect a 50/50 split but a streamlined console OS should be able to handle memory well and not hog too much.

They wouldn't use expensive GDDR5 RAM if they were going to give it all to the CPU. I would hope for a 25% system /75% GPU split as a worse case scenario.

 

I wonder how much of that is allocated to the video compression. Or do you think that has it's own memory?

 

From Anandtech, some updated info on CPU/GPU...

 

But what does it all mean, Basil?

 

Mobile CPU tech that has some limitations going forward combined with a GPU that isn't at the bleeding edge of current PC tech, but with high-end GPU memory. In all, Anandtech thinks it's a good system.

 

Final Fantasy PS4!? Square-enix best not fuck this up after the Lightening series and being twats about Versus.

Is it true the PS4 is as powerful as high end PC's now?

 

Not really, it's about as powerful as a mid ranged TV but it has elephant memory

 

That's very similar to my GPUs, EVGA GTX 670 4GB cards. You're just trying to rub it in that I blew way more money than I should have, aren't you?

 

well, to put it in perspective. a single geforce gtx 670 throws out 2.46 TFLOPS. and alterego quoted anandtech above that sony confirmed the ps4's gpu throw out 1.84 TFLOPS.

 

This isn't a next-gen console. It's a this-gen console.

 

Haven't the last few generations of consoles been below top PC spec?

 

I thought the current 360 needed an SLi set up to match it when it was released.

 

Yes relatively speaking the 360 was much better off compared to PC's of 2005 than the PS4/720 is compared to current PC's, but not in every metric. Keen in mind that in 2005 top end graphics cards used 100w, now, they are over 200w. That's already on the upper ceiling for power use in a console with a high end GPU alone. Basically high end PC parts have expanded into a higher power envelope since 2005.

That said I think the PS4 looks really impressive given the power and cost constraints. Let's just hope it's not too expensive.

 

Not really. I think you should think about what you've done.

 

Everyone knows grey hair is next gen

 

The memory is just one aspect, while impressive, the rest of the GPU is comparable to a $200 graphics card (7850). 8GB of GDDR5 will probably cost around $60-100 by itself. I'm not sure of an exact figure, but 2GB costs around $20 and 4GB a little over $40. These are actual AIB partner costs, no need to deduce prices based on retail cards with everything else included.

The amount of fast ram is great and will allow for a very different gaming experience to what we have today in the long run. The overall GPU 'grunt' however is very mid range. In a closed system with a thin API this will result in the something more capable than what's in PC's today however. You'll probably need a GTX Titan to play ports of PS4 games in 2 years time. Of course by then PC's will be well ahead again, but most of that advantage will be used to drive higher resolution (4k).

Basically, the PS4 looks to be about the best gaming technology one could hope for right now in a <200w small box. The CPU could be a little better without blowing out the power budget, but that would only be possible by going with Intel which means no advantages of the SoC like HSA and proper unified memory access. So while it doesn't have the grunt of high end PC's, it sure is well designed for the future and will leave current PC's in the dust once devs make the most of the hardware.
