I believe SONY is not scared showing off their PS4. They flat out front revealed their specifications. Here is a quick run down. Main Processor
Single-chip custom processor
CPU : x86-64 AMD “Jaguar”, 8 cores
GPU : 1.84 TFLOPS, AMD next-generation Radeon™ based graphics engine
Memory GDDR5 8GB Built-in Optical Drive
Disk Drive (read only)
Super-Speed USB (USB 3.0) 、AUX Communication
Ethernet (10BASE-T, 100BASE-TX, 1000BASE-T)
IEEE 802.11 b/g/n
Bluetooth® 2.1 (EDR) AV output
Digital Output (optical)
They have put a massive RAM. Sony have learned their lessons and have put in a powerful 8GB GDDR5 RAM, which should make the system future proof for years.
Used Kevin Krewell, a longtime chip analyst at the Linley Group, for his reaction.
The machine uses its GPU for particle physics processing, which indicates GPU Compute, Krewell said. That likely means it will support OpenCL computing, or using the graphics cores to do nongraphics tasks. The specs in fact say that the GPU has 18 compute units that collectively produce 1.84 teraflops of computing power. Combined with the CPU, the computing power tops 2 teraflops.
Krewell also aid that the 176GB/s of memory bandwidth is 3.7 times the bandwidth of the Cell processor (made by IBM for the PlayStation 3, with Rambus XDR main memory) and the Nvidia RSX (GDDR3) graphics chip memory bandwidth combined. The 8GB of GDDR5 memory is 16 times the memory of the PS3. Cerny mentioned that the machine will turn on instantly. You can press the power button and put the game into suspend mode. It will stop where it is, and then you can tap the power button later to resume the game immediately. You can also use the PlayStation Vita, a smartphone or tablet as a second screen. You can use that second screen as a remote, or use it perform some actions from afar. You can, for instance, view a map on a second screen while playing an adventure game. Or you could use your second screen to spectate games being played by your friends.
“It’s very comparable to a mid- to high-end gaming PC
,” Krewell said. “Even though the CPU is combined with the GPU on one die, like most PC processors today, the higher bandwidth memory and custom design indicates it should have graphics performance more like a discrete GPU found in a gaming PC.”
Cerny mentioned that the CPU has eight cores and a state-of-the-art GPU
,with a combined two teraflops of computational performance. He showed the Havok physics engine running on the PS4 while consuming very little of the system’s overall computing power.
Cerny acknowledged that the “radical technology” of the past Cell processor got in the way of simplicity for game developers. So the new machine is making the leap to PC technology, which can easily run engines such as Epic Games’ Unreal Engine 4. Sony showed a demo of Unreal Engine 4, reportedly running in real time on the PS4. http://venturebeat.com/20...potential-performance/
I like that SONY is not scared showing off their consoles power and revealing few games now. They strongly believe have the most powerful console, which I do, and are not worried about their competition. I think SONY did a great job with the specs of the system. State of the GPU with also a great CPU.
