Upcoming Playstation Codenamed "NEO" - Features A Powerful Polaris GPU and 4.19 TFLOPS of Performance

Details most the upcoming and more than powerful variant of the PS4 have simply leaked out. Code-named the "PS NEO", the console volition get pregnant hardware upgrades on both the CPU and GPU side. The data comes from the website GiantBomb (via HWbattle). If the leak is accurate, Sony will be more than doubling the corporeality of horsepower available to Devs in the upgraded version - something completely in-line with their plans to button PSVR and 4K content.

'Playstation NEO' will feature 36 CU Polaris GPU with more than four.19 TFLOPs of horsepower

The report from GiantBomb cites its own sources and seems to be fairly in-line with what was expected from the company. AMD supplies both Microsoft and Sony with the APUs within the consoles and has recently transitioned to the 14nm FinFET node from Samsung/GloFo. Equally nosotros exclusively revealed a few months back, the visitor has had plans for a long time to supply 14nm based processors to the console manufacturers for increased functioning per watt gains for a long time now. According to the report, PS Neo consoles volition accept two modes: a Base Way and a Neo Mode. The Base Mode volition run the hardware virtually indistinguishably from the PS4 original models, while equally the Neo mode will allow developers to gain full access to the increased hardware capability of the PS Neo.

Every bit many of you lot will know, the current generation of consoles does not take the necessary horsepower to drive powerful VR headsets such equally the Oculus Rift and the HTC Vive - both of which have the 2160 @90fps standard. Unless of course, you drastically cut graphics quality (which volition exist the case in most PSVR use cases). This is an approach which volition work well because visual fidelity is much harder to discern in a stereoscopic environment than a second one. In any example, with an almost two.3x increase in power with the upgraded hardware, PS Neo should be able to handle VR loads for PSVR hands - also as button moderately intensive 4K content.

PS NEO volition withal be rocking the same old Jaguar architecture on the CPU side of things with 8 cores (the aforementioned 4 + four combination present in the original model). The clock charge per unit yet, will be increased to 2.1 Ghz, owing most probably to an efficient architectural revision. The corporeality of CUs present in the PS4 GPU volition be increased from 18 to 36 – which is exactly double (duh) of the original specification. The GPU of grade is the most important component when it comes to gaming and this boost in power will allow devs to push VR and 4K content. The bandwidth has also been increased from 176 GB/s to 218 GB/south. The website besides states that an additional 512 MiB chunk of memory will be available to the developers in NEO mode.

Crunching the numbers of PS Neo

Fortunately for us, GiantBomb has listed all the key numbers required for a complete technical break down. Bold the number of stream processors per CU remains constant in 4th Generation GCN (Polaris compages) we are looking at total of 2304 Stream Processors. Since GCN can handle two instructions per clock, we are looking at roughly 4.19 TFLOPs of horsepower available to the developers. The memory bandwidth stated is 218 GB/s, and since we know the autobus width to be 256 bits, nosotros can work backwards to arrive at the the new and updated Retentivity Clock: 1703 Mhz (6812 Mhz effective). The jump to 14nm FinFET will let AMD to leverage roughly 2.5 times the functioning per watt so this increased hardware should occupy roughly the same electric footprint. Here are the detailed calculations for anyone interested (assuming of form, that this leak turns out to be accurate):

Calculation Memory Clock:

218 GB/s = 218,000 MB/s
218000/(256/8) = 6812.5 Mhz (Effective)
6812.5/iv = 1703.125 Mhz
218 GB/s ~ 1703 Mhz

Adding TFLOPs:

36 CUs * 64 (64 SPs per CU) = 2304 SP
2304*2 = 4608 instructions per clock
4604 * 911 Mhz = 4197888000
36 CUs @ 911 Mhz ~ 4.19 TFLOPs
