probably wont work like that.

There's something I really don't get in the specs section. Can someone tell me how the console supposed to use 8 gig of GDDR memory? GDDR memory is for graphics cards, is the system sharing the same ram for the graphics and the system? Or they just made a mistake and called their ram GDDR when its only DDR? If so, what about the total ram available for the GPU?

The PlayStation 4 will utilize a semi-custom accelerated processing unit (APU) developed by AMD in coordination with Sony.[22] Its APU will be a single-chip solution that combines a central processing unit (CPU) and graphics processing unit (GPU), as well as other components such as a memory controller and video decoder.[22] The CPU consists of eight x86-64 cores based on the upcoming Jaguar architecture from AMD.[22] The GPU consists of 18 compute units to produce a theoretical peak performance of 1.84 TFLOPS.[16] This processing power can be used for graphics, physics simulation, or a combination of the two. The console also includes secondary custom chips that handle tasks associated with downloading, uploading, and social gameplay.[23][24] These tasks can be handled seamlessly in the background during gameplay or while the system is in sleep mode.[25] Though not much is currently known of the PS4's audio capabilities, the console also contains a dedicated hardware audio module, which can support in-game chat with minimal external resources as well as "a very large number" of MP3 streams for use in in-game audio.[26]
The PS4 will contain 8 GB of GDDR5 unified system memory with a maximum bandwidth of 176 GB/s.[16][27] This is 16 times the amount found in the PS3, and is expected to give the console considerable longevity.[19][28] The unified memory architecture allows the CPU and GPU to access a consolidated memory, removing the need for separate, dedicated memory pools.[28]
The read-only optical drive will read Blu-ray discs at 6x CAV for a maximum read speed of 27 MB/s – a significant upgrade from the PS3's 2x speeds that were capped at 9MB/s.[28][29] To further enhance optical drive performance, the PS4 will feature a hardware on-the-fly Zlib decompression module, allowing for greater real-term bandwidth, whilst at the same time, the console will continuously cache data onto its hard disk, even buffering unread data when a game isn't actively accessing the optical drive, forming part of Sony's PlayGo strategy.[26] Early reports indicate that the Blu-ray Disc drive will not be capable of reading quad-layer 100 GB discs, a new Blu-ray Disc technology designed to support 4K resolution.[28] Although the console will support photos and videos at 4K resolution, the system is not expected to be able to render games beyond 1080p.[30][31] The console will include a 500-gigabyte hard drive for additional storage,[1] which can be upgraded by the user.[2]
The PlayStation 4 will feature 802.11 b/g/n wireless network connectivity, Ethernet (10BASE-T, 100BASE-TX and 1000BASE-T), Bluetooth 2.1, and two USB 3.0 ports.[16][28] An auxiliary port will also be included for connection to the PlayStation 4 Eye, a motion detection digital camera device first introduced on the PS3.[16] A mono headset, which can be plugged into the DualShock 4, will come bundled with the system.[32] Audio/video output options include HDMI and optical S/PDIF.[16]

FYI the launch version of the PS4 is sold out on Amazon.com there is still the standard version which is not much different, not sure what the difference is though

They call it unified memory so maybe its shared between cpu and gpu or something ?

Im really looking to see more from FFXV. Looked awesome and a little different combat wise. Anyone know if they had a floor demo or anything shown other than during the PS4 reveal?

The PS4, in comparison, has an 8-core Jaguar AMD CPU, with a GPU that’s around the same level as the Radeon 7870 (which is significantly more powerful than the 7790). The PS4 has 8GB of GDDR5 RAM, providing 176GB/s of bandwidth to both the CPU and GPU. The Xbox One mostly ameliorates this difference with 32MB of high-speed SRAM on the GPU, but it will be a more complex architecture to take advantage of.

The ram goes to both. In both systems.

Basically 3 gigs is reserved (If i remember correctly) for non gaming purposes and the other 5 are for the GPU's. The numbers could be wrong but that's how it works.

If its only as powerful as a 7870 then most pc gamers are still ahead of the curve and have little to no reason to upgrade. Shame all my friends kept telling me current pc specs would skyrocket but i just seriously doubt that.

Well its not that simple.
As suggested, while the GPU is probably inferior than some PC ones the RAM is better than most, the console is a lot more optimised than a PC, is almost dedicated to games and doesn't have to run a greedy OS like Windows. Also devs have a way easier job at optimizing a game since everybody has the same hardware.

So while its very possible that a high end PC will be superior (and more PC in a couple of years), I think we won't be disappointed by the first years of games in term of graphics. Unless you have unrealistic expectations of course

No point comparing graphic between console and PC, Console will be beat in term of graphic within a year of its release since its a fixed machine without possible of upgrade.
Why console still exist and flourish is the style of gaming it bring. You can game with your PC, but there are alot games will be much more enjoy able when you laid back on your couch and play it on your TV. The controllers are also a big part of console experience.
PC as powerful as it is, still has its limit in term of game presentation.

Not to start this up again like in the xbox thread, but i can do all of that on my pc with a controller if i want. The only thing that the console has an "edge" on would be individual franchises. But thats a personal taste and cant be used to effectively score one side or the other.

Yeah you are right. But for me nothing can beat playing RPG alone or playing sports games with my friends in my living room and console is the flatform for that kind of activity. Its just feel natural just like playing SC2 on a computer, I refuse to play any kind of RTS games on console.
