| nanarchy said: BULLSHIT. the CPU is not some magical beast optimised for gaming at all. That is the easiest item to outperform with a relativley cheap quad core i5. You also don't have 8GB GDDR5 allocated to the GPU, it is a unified memory model so that OS has to live in and use that RAM too. 8GB DDR3 + a decent GPU with 2-3GB DEDICATED of GDDR5 will comfortably outperform it. Without monitor, keyboard etc you should be able to beat performance with budget parts. Add little more though and you can completely blitz it. |
Sorry, but you are wrong here. The unified memory in this case improves vastly the performance. People think its bad because of onboard video cards. A PC onboard video card shares DDR3 memory with the CPU. That is worse than having DDR3 for CPU and GDDR5 for the GPU. But on PS4 there is a unified GDDR5 architecture. That means that the CPU and the GPU can share data for free. You can run heavy physics operation on the GPU easily without passing by a slow PCI Express interface. While the GPU on PS4 can access data that is being used by the CPU at 176GB/s, a regular PC would have to pass it for the PCI Express interface (15GB/s in version 3.0). That is a massive performance impact that some timestimes actually makes developer do a calculation that would be faster on the GPU using the CPU only because of it. So it won't outperform the PS4 architecture, it will actually be underperforming by a significant margin.
I'm gonna put another interesting data. CPU. If you grab a more powerful CPU, even a 16-core one, it won't help you that much. At some years, we had nice single core CPUs using the main memory. Now we have 8 or 16 CPUs using the same memory and splitting bandwidth. The number of cores and general CPU speed improves much faster than the memory bandwidth (its called the "memory wall") and it only will got worse. PS4 has a good advantage for using 8 cores with very fast memory. We are in a point in tech that throwing horsepower can, by the first time in computing history, only make things worse. Software optimization is what will have to drive things forward.
