Being based on low-power/low-cost microprocessor technology and current-generation graphics processing technology from Advanced Micro Devices, Sony PlayStation 4 will unlikely offer horsepower comparable to even today’s gaming PCs. However, the PS4 has a secret weapon that even high-end PCs will not sport for a couple of years: 8GB of GDDR5 memory. As it appears, game developers believe in this feature.

“[PlayStation 4] is a perfect fit for the types of games we do, and we are confident that we will bring open-world gaming to a whole new level because of it. I am glad Sony decided to go with 8GB GDDR5 RAM because it means that the PS4 will out-power most PCs for years to come,” said Linus Blomberg, chief technology officer and co-founder of Avalanche Studios, in an interview with Gamingbolt web-site.

Sony PlayStation 4 is based on a semi-custom AMD Fusion system-on-chip that integrates eight AMD x86 Jaguar cores, custom AMD Radeon HD core with unified array of 18 AMD GCN-like compute units (1152 stream processors which collectively generate 1.84TFLOPS of computer power that can freely be applied to graphics, simulation tasks, or some mixture of the two), various special-purpose hardware blocks as well as multi-channel GDDR5 memory controller. The PS4 will come with 8GB of unified GDDR5 memory sub-system (with 176GB/s bandwidth) for both CPU and GPU as well as large-capacity hard disk drive.

Even by today’s standards Sony PlayStation 4 can be considered as an entry-level gaming system and is significantly behind mainstream and high-end machines. Still, when compared to average PCs, which feature dual-core microprocessors, integrated or entry-level graphics as well as around 4GB of DDR3 memory, then Sony’s PS4 is a powerhouse.

Still, PS4 is not only about pure performance, but also about other features and capabilities.

“The PS4 will not only be a very powerful gaming machine from a hardware perspective, but it will also be a social tool and integrated marketplace more akin to the successful mobile devices. It’s the best of all worlds in a way; great performance for demanding high-end gaming, good social ecosystem and connectivity, and integrated business marketplace,” added Mr. Blomberg.

Sony PS4 will be equipped with Blu-ray disc drive capable of reading BDs at 6x and DVDs at 8x speeds, USB 3.0 connectivity in addition to a proprietary aux port, Gigabit Ethernet port, 802.11b/g/n Wi-Fi, Bluetooth 2.1 EDR wireless technology as well as HDMI, optical and analog outputs. The new system will also utilize new DualShock 4 game controller with integrated touchpad as well as better motion sensing thanks to new PS4 Eye tracking cameras.

It's an interesting comment.

On it's face the RAM spec makes the overall performance of the GPU similar to the 7870 with 2GB, even though the GPU core is of lesser spec (since it really only really needs about 60% of that bw and 2GB for 1080p in the current landscape). That's not taking into account what the CPU will use, but it's likely minimal.

While certainly more versatile because of the ram spec, and it should lead to some interesting things perhaps not possible on current or immediate future GPU/APUs until we hit 8Gb (1GB chips) and GDDR6 (2x bw) in the next couple/few years; Both will happen because of 4k and increased requirements of GPU calculations by that time. At that point, we're back to where we started.

Also, while again the ram could allow for a more varied design of games, there is no doubt more targeted designs per resolution could be and are more efficient in the PC space.

I really wonder if they're so thrilled to have 8GB, or simply knew they would be screwed (compared to a modern or future average PC) with only 4GB total. It's one thing to see 8GB as a huge boon to this design...which I don't...it's another to see 4GB for cpu + gpu for the next 7 years as a detriment, which I certainly do.

I think the point here is that the CPU is hooked to multiple times the memory bandwidth you get in PCs, even in dual or triple channel.

Meh consoles...
This is what has been holding us back for so many years in pc gaming. pc gaming has much more potential than this silly consoles.
Consoles are dead in my eyes. Their time is over.
The only good news about this, is if they manage to make good use of the 8GB of GDDR5 memory which I highly doubt by the way, this will probably mean more reasonable prices on pc graphics cards with lots of memory.

Come back to me when a console can make me money via a bazillion productivity apps OTHERWISE STFU as I can still build a < $1000 system that will out-pace most, do waayy more in the long run, be expandable (not locked for 5-7 years), and I can source parts locally or anywhere.

PS4 is perhaps *MAYBE* fine for its first year but PCs are like Smartphone: EVERY WEEK it seems something new is being announced so tell me how does one remotely compete with that kind of progress?

This comment is more targeted towards the average gaming pc, which if you look at steam, then yea it will outpace the average joe. Enthusiast gamer rigs will surpass it immediately.

I am afraid that is not the case.
An average pc will outperform any console out there, even the new ones that will be with us in the near future. You don't need Enthusiast rig to outperform these consoles.

You clearly didn't look at the steam statistics. The average gaming computer used is quite pathetic.

I don't care about steam's pathetic statistics.
I am talking about a middle range pc setup for gaming will kick the crap out of any console. That is why there is no need for top notch hardware to outperform any console.
Clearly those with that kind of low specs used for gaming have no idea about what kind of hardware do they actually need to have a reasonably good gaming experience. And they clearly don't know anything about hardware or they are not actual gamers and they don't give a damn if the graphics are very poor and a very laggy gaming experience.

So, aside from the facts of what the world is doing... which is what this article and quote are referencing you are citing only your view on popular opinion. So what point are you trying to make that would have anything to do with this article? Right.

What Linus Blomberg have said is stupid. The 8 GB of RAM in PS4 is shared between 8 CPU and 1152 stream processors. That takes some serious bandwidth to keep those pieces of hardware loaded with data, so Sony used GDDR5 to take care of the bandwidth problems. Depending on the games running on a PS4, some games may take as much as 6 GB of RAM to run and that only gives 2 GB for video memory. In this case, this article is misleading that 8 GB of GDDR5 RAM is more than today's systems capabilities. If Sony have gone with 16 GB of GDDR5 than you can talk that it has more capabilities than today's systems.

You made a good point there. I didn't actually think about this.
So basically for video memory there is no way they would use all of those 8gb of gddr5.
My guess would be somewhere about 3 to 3.5gb tops depending on the game. Still I think there would be very few games that will use that amount of video memory.

That, just that.

Like none of the entry level GPUs can use that 1 or 2 GB of GDDR5 memory, that some makers add on them.

OK you have to support what makes you money I guess, but telling bullshits like that...

And no, the average PC Gaming system is not dual core celeron...
Comparing PS4 to my mother's computer says nothing at all, compare it to my system which is a mediocre gaming one (Phenom II x6, 7850, 8GB DDR3 1600) and tell me then.
PS4 will be midrange for todays standards if we take into account the stripped off OS that will have, to use the hardware better.

In a couple of months that amd/intel and amd/nvidia will get their new cpu and gpu out, PS4 will hardly be entry level.

And no, steam statistics are worthless, if my mother make a steam account to play plants vs zombies that doesn't make her system a gaming one...

Why not use DDR3 for the CPU cores and GDDR5 for the GPU? I think this way (that I said) is less expensive and give a bigger performance.

I think PS4 should have 1,5 or 2 GB of GDDR5 for the GPU and 4 or 6 GB of DDR3 for the CPU cores.

Unified shared resources is the future. games can use more video ram or system ram were required rather then limit it to one or the other..

Xbox360 had 512MB's of unified ram
PS3 has 256mbs Video & 256Mbs System Memory

Overall (over time) the Xbox360's approach was the better one

In other words, I think that the final cost (of the PS4) could be the same or a little bit smaller in this way (with 6 GB DDR3 for the CPU cores and with 2 GB GDDR5 for the GPU) and with a better performance.

You are all missing the point of consoles, THEY are a cost effective gaming system that never need to be replaced, upgraded or touched. You spend the money once and they just sit there like a DVD player and you use them. Couldn't be more simple. and if you people think you can buy a PC that can run games like a console does your nuts.

Bf3 on a $140 Xbox360 runs great... Try and play BF3 on a $140 PC.. NO CHANCE!!

BF4 on a $499 PS4 ( when i comes out ) will run and look amazing

Try and play BF4 with the same graphics settings as PS4 on a $499 PC at the time of release. no chance!

And over the life of the console remember the price drops so that $299 PS4 will be playing the latest and greatest while your $1000 PC will also be playing those same games remember thats - $1000 VS $299 and when the PS4 dropes to $199 then you will need to spend another $1000 upgrading your PC to play the SAME games.

Over the lifetime of a console a PC gamer spends more upgrading his PC.

I'm a 100% PC gamer.. playing Guild Wars 2 mostly so yeah.. my views on the matter are just facts nothing more.

Trying to compare consoles to pc's is pointless. There is no apples to apples comparison.

Consoles sold at cost or below cost so you can never truly compare a 400-500 next gen console to a 400-500 pc because there is no company that I'm aware of that sells pcs or components at cost to consumers.

All this e-peen waiving is pointless. I for one am excited about the consoles. I never plan on buying a console but giving game programmers access to 8 gigs of ram regardless if it was ddr2,3,4 or gddR5-6 and give em access to dx11.1 means the end of crappy ports. Try explaining a port to a console only player.

Hell I had a coworker who owns a ps3 refuses to buy a ps4 because it won't do "4k gaming" tried explaining to him that his ps3 isn't doing true 1080p gaming. Tried to explain up scaling but went nowhere point is let the console players get a huge upgrade in power and let us pc player stop getting crap dx9 ports

wouldn't the best solution be that the consoles shorten there lifespans from 6 to 7 years to 4 to 5 years. so the next upgrade would future GDDR6 (or DDR4 or maybe DDR5 by then) and DX12(or opengl) and a better "fusion" core. ok the consumer wouldn't like it. but it would help the gaming industry move forward and avoid problems like the PS3's (skyrim) that crashed because of the low amount of ram or the XBOX 360 that get overheated.

The CPU and GPU is a single chip with shared memory controller. It should be several times faster than todays extremly unoptimized PC machines fighting with milions of driver codes.

The only problem i see is the loading times. Loading 8GB of data to memory from blue ray will take 5+ minutes. U will need to instal each game to HD and the games will take up a lot more space than PS3 games. So not much left from the console experience.

To share the same memory controller and the same bus is not a plus here.
