How does the PS4 differ from a high-end gaming computer? Well, for one thing, one is a game console and the other one doesn't suck. :D

According to Cerny, PS4 addresses the hiccups that can come from the communication between CPU, GPU, and RAM in a traditional PC. "A typical PC GPU has two buses," Cerny told Gamasutra in a very detailed technical write-up. "There's a bus the GPU uses to access VRAM, and there is a second bus that goes over the PCI Express that the GPU uses to access system memory. But whichever bus is used, the internal caches of the GPU become a significant barrier to CPU/GPU communication--any time the GPU wants to read information the CPU wrote, or the GPU wants to write information so that the CPU can see it, time-consuming flushes of the GPU internal caches are required."

Well shit who knew it would take Sony to actually build a computer that works better.. dur duh dur
 
One very important difference it that a PC isn't completely crippled by DRM. Can you run Linux on the PS4?
 
Can you upgrade the PS4 and will it beat my Titan SLI? If not then pass.

Better to have 'crippling' DRM just on the ps4 system and not be plagued by Game crippling DRM of all flavors on the PC? :D
 
Like piracy was ever a serious concern for the PS3. Even if you managed to go through the hours of flashing and dealing with a modded PS3 you still have 25-50GB's games to deal with. Top that off with a data cap via your ISP and its pointless.

Best way to combat piracy on consoles? Simply make the games gigantic. Most people do not have a big broadband pipe and many have data caps to deal with. It won't fuck with consumers who buy their games honestly and rightfully and it'll halt piracy for the time being but putting it out of the reach of many people even remotely interested.
 
"We can pass almost 20 gigabytes a second down that bus," Cerny said, pointing out that it's "larger than the PCIe on most PCs!"

Pcie 3.0 x16 can pass 32GB/s

hence the most statement, since MOST wont have that.
 
I have 2 Radeon 7950s in Crossfire, can it match that? Are the little cores in the PS4 a match for even a low-end Core processor?

Will I buy a PS4 or Xbox whatever? Maybe if there are good enough games that necessitate it. Will it be more powerful than even my current PC, Almost assuredly not.

Nothing can match the stutter of a 7950 crossfire system....
 
:raises hand:

Looking to be faster and better over all than the 720 and I LOVE me some PS4 exclusives! Uncharted 4 here I come!!!
 
I might buy it like 4 years down the road if there are exclusives that seem REALLY REALLY REALLY good.
 
Im only in for a Wii U this time around in the console department. But that is because I know Nintendo will not be making ports.
 
I'm a sucker for new stuff but going to pass on this one money will be better spent on a new GPU

There are so many things wrong with your statements.

Let's start with the price.

Rumoured to start at $429

And what you get for that.

8 Core Jaguar CPU (Rumoured to be at 2Ghz)
8GB of GDDR5 RAM,
1.84 T-FLOPS, AMD Radeon GPU (Closest I could find online is a GeForce 580 overclocked by 30%, that hits 1.85TFlops and between a Radeon HD 6850 and 6870 which are 1500 and 2000 GFlops respectively)
BluRay Drive,
Hard Drive sizes probably determines the price differences. My best guess is that the $429 model will have something like 250GB.
Gigabit, Wifi, Bluetooth

Can you build something like that with a $429 budget? Oh sorry. One of your cards alone nearly exceeds that.

lol, this.

i get it, your rig that costs as much as a decent used car is awesome, but the PS4 only cost me a couple days salary.
 
I'll buy one, play around in the new UI, then turn it off.

It's likely going to be selling at a loss, which makes it pretty difficult to beat. I think the PS3 was selling at something stupid like $200+ loss per unit at launch. I don't think the PS4 will be quite as absurd, but it's still unlikely to be profitable per unit.
 
Since the next XBox and PS4 have nearly identical specs, would it be too much to expect someone to eventually make it to where you could play xbox games on the PS4? I Know that you can stick a playstation CD into a modded original xbox and play it, and that's with different emulated hardware.

Then if both systems emulate the older generations to play their games and it's figured out how to play next gen games on the opposite's system...

But he is also talking about a snapshot in PC technology for the next 5 or more years and this is already below what we would call state of the art.
 
Mouse and keyboard are poorly optimized for consoles. I enjoy when a die hard console gamer says they can beat a PC gamer if the fps games were cross platform.
 
That bandwith is 100% useless since the CPU and GPU do not have enough power to pump through that volume fast enough anyway making it useless for games.
 
fucking Geforce titan GPU don't even use PCI-E bandwith 100%. So you can have as much as you want the CPU and GPU are still bottlenecks.


Just like the fucking N64 could use 64bit data but used 32bit most of the time because of the lame system bus speed and the same with the genesis that could use 32bit on the cpu but only did 16 because it was limtied by the bus.


now it is the reverse you have huge bandwith and bus speeds but suck ass CPU and GPU in the consoles that will never use that speed for games anytime soon if ever unless the programmers are gods.

Though both systems look similar in terms of CPU/GPU, there are pretty serious differences in terms of memory and structure.

According to the dev friends I know working on both, they aren't quite as close as they seem.
 
I don't understand what's the purpose of that article. Theoretical numbers are just that. So on paper, the bandwidth between the CPU and GPU is slightly higher. Does that make video games better? I don't know if that would even show up in benchmarks.
 
FLOPS /= performance

Just because the GPU in it can do 1.84TFLOPS, it doesn't mean that it is a powerful gaming GPU, that's just the raw computational power.
Remember, the HD4850 could do 1TFLOPS back in 2008, yet GPUs like an older GTX480 which can do about 1.3TFLOPS, are far more than 1.3 times as fast in games and 3D applications.


Also, the whole 20GB/s transfer rate is nice, but no single GPU solution requires this over PCI-E.
Essentially, the article is saying that PCI-E is a bottleneck, even though dual-GPU solutions barely even utilize PCI-E 2.0 x16, which is only 16GB/s (8GB/s up and down).

If PCI-E were truly a bottleneck, then we would have seen full saturation on the PCI-E bus years ago, yet, that simply is not true.
Here is a VERY old example, and the fact that it is old should mean that there would have been even more of a bottleneck back then, yet there wasn't, and still isn't:

batman-physx-pci-e.jpg


If PCI-E were really a bottleneck, there would have been far more than 3fps lost when moving from 16x to 8x.
In fact, it should have almost cut the fps in half, yet it didn't, and this was also with a PhysX GPU involved as well, which should have bottlenecked even more on the CPU-side, yet, it didn't!

The article, and author, can shove it. ;)

You could get close. You'd have to settle for DDR3 and not GDDR. But a new 7930 (7870 le) goes for around $200 new on sale. The rest can be had for cheap. CPU can be an alternative last-gen model.
