DIGITAL FOUNDRY: PS4 Vs Neo Vs XboxOne Vs Scorpiohttp://www.eurogamer.net/articles/digitalfoundry-2016-xbox-one-project-scorpio-spec-analysis Aviso, articulo para generar debate en base a especificaciones totalmente desconocidas
Memory: 12GB of GDDR5?
Microsoft also dropped some hard figures in terms of memory bandwidth too, telling us that Scorpio has over 320GB/s of throughput. This gives us a couple of useful data points. Firstly, it's almost certainly the case that the ESRAM experiment on Xbox One is now a thing of the past - Microsoft will be following the approach pioneered by Sony in using a single, unified pool of memory based on PC graphics RAM technology. Which technology that is remains to be seen - will it be GDDR5 or the faster G5X found in Nvidia's GTX 1080?
The stated figure of 320GB/s can be achieved with 8GB of G5X using a 256-bit bus, or alternatively it could be using a 384-bit interface paired with 12GB of GDDR5. Now, this is where the stylised renderings of the Scorpio motherboard prove rather useful as we can count the amount of memory modules on the board - 12 memory chips are visible, confirming the use of current-gen memory tech and not the HBM2 we expect to see on Vega and Nvidia's next-gen Titan. This also seems to suggest that Scorpio has another big advantage over PlayStation 4K Neo - not just over 100GB/s more bandwidth, but also an additional 4GB of onboard RAM.
Sobre la memoria no saben que pensar, si es 8 GB GDDR5X con un bus de 256bits o 12GB GDDR5 con un bus de 256 bits. En cualquier caso lo unico que sabemos es el ancho de 320Gb/s asi que se especula con estas dos posibilidades.
Neo por otro lado se espcula que tendra la misma cantidad de memoria con un ligero overclock, subiendo asi ligeramente el ancho de banda de 176 a 218Gb/s
First up, let's discuss the GPU - the area of the spec that Microsoft is clearly most proud of. The rumoured six TFLOPs of processing power is confirmed, out-stripping the 4.2TF found in PlayStation Neo by quite some margin. It's around 40 per cent faster, calling to mind the advantage PS4 had over Xbox One.We know how Sony has achieved its performance target - it is almost certainly utilising the AMD Polaris 10 graphics core, using 36 next-gen GCN compute units clocked at 911MHz. Essentially, it is a downclocked version of the Radeon RX 480 graphics card - AMD's upcoming $199 next-gen GPU, aimed squarely at the mainstream gamer while also offering good, entry-level VR capabilities. We can be fairly sure that this GPU is a cut-down version of a yet-to-be-seen product, quite possibly one with 40 compute units. By leaving a portion of the CUs deactivated, imperfect chips can be used from the production line - it's a tactic used on both PS4 and Xbox One, both of which have two offline CUs on the silicon.
However, based on the differential in spec between Neo and Scorpio, it's unlikely that the new Microsoft console uses Polaris at all. A 40 CU part would need a mighty overclock to hit 6TF, and based on the rendered imagery we've seen, the heating assembly planned for Scorpio looks a little lacklustre. With that in mind, our money is on a downclocked version of AMD's upcoming Vega technology.
Thanks to an AMD engineer rather unwisely
posting a partial spec for Vega on his LinkedIn profile (!) we know that the fully enabled processor features 64 compute units. Assuming that this is cut down to 56 CUs (as in the Radeon R9 Fury, a pared back version of the 64 CU Fury X), a clock speed in the 830-850MHz region looks likely. Alternatively, and perhaps more likely, we could be seeing 60 CUs at 800MHz. Both represent a substantial increase over PlayStation 4K Neo, while the raw increase to performance over PS4 and Xbox One is obviously much larger.
Centrandose en la GPU, especulan con que Neo llevara una RX 480 con downclock y 36 GCN (frente a los 18 actuales de Ps4) mientras que con Scorpio especulan que tras los datos de Vega, con 64 computer units, la consola tendria una version recortada con 56 ó 60 computer units (12 actualmente en One), haciendo que la diferencia sea mucho mayor que la que hay entre PS4 y XboxOne.
CPU: Eight cores, but what are they?
Microsoft didn't spend much time talking about the CPU technology found in Scorpio and if we were to be cynical about it, we'd suggest that it's because it's not going to show that much improvement over Xbox One. Just one specification was revealed - that Scorpio would have eight CPU cores, which brings it into line with the existing Xbox One, PS4 and indeed PS4K Neo.
There are two theoretical CPU technologies available to Microsoft here - the existing Jaguar cores (or perhaps a more modern version thereof), or AMD's upcoming Zen technology. Weighing the balance of probabilities, we'd say that it's unlikely to be Zen - if it were, we'd expect Microsoft to have made a much bigger deal of it. But secondly, what we know of the eight-core Zen is that it's a high-end desktop processor that's likely to require a large area of silicon. Integrating that alongside an already large GPU core seems overly ambitious.
With that in mind, we expect the disparity between CPU power and GPU in the consoles to grow even wider, and the importance of DX12 and GPGPU grows even more important - more tasks traditionally associated with the CPU will be hived off to the graphics hardware instead. Assuming Scorpio is indeed still using AMD's more mobile-orientated CPU cores, we should at least expect higher clock-speeds there - PlayStation Neo runs its cores at 2.1GHz vs the 'stock' 1.6GHz found on PS4.
En CPU, Neo llevaria la misma que Ps4 pero con overlock a 2,1Ghz (y superando asi el overclock de la CPU de One) y Scorpio no saben que opinar al respecto, aunque por el tema de compatibilidad total con One creen que llevaran una Jaguar como Neo, PS4 y One, aunque quizas una version mas moderna.
