Citazione di: Parsifal il 19 Marzo, 2019, 19:31:31L'infrastruttura google è abbastanza potente, superiore a quella di amazon a quanto pare che dovrebbe/vorrebbe fare una cosa del genere.Bisogna vedere anche quanti sh svilupperanno per questa stadia.
Citazione di: stobbArt il 19 Marzo, 2019, 21:04:16in teoria a livello di datacenter microsoft e amazon dovrebbero essere decisamente avanti a google

CitazioneGoogle's Stadia specsGoogle has released the following data for Stadia. It's a curious mixture of data points, combining the kind of minutiae rarely released on some components along with notable omissions elsewhere, such as the amount of cores/threads available for developers on the CPU. Regardless, it paints a picture of a highly capable system, clearly more powerful than both the base and enhanced consoles of the moment.- Custom 2.7GHz hyper-threaded x86 CPU with AVX2 SIMD and 9.5MB L2+L3 cache- Custom AMD GPU with HBM2 memory and 56 compute units, capable of 10.7 teraflops- 16GB of RAM with up to 484GB/s of performance- SSD cloud storageGoogle says that this hardware can be stacked, that CPU and GPU compute is 'elastic', so multiple instances of this hardware can be used to create more ambitious games. The firm also refers to this configuration as its 'first-gen' system, the idea being that datacentre hardware will evolve over time with no user-side upgrades required.[...]There's no specific confirmation of who is supplying the custom CPU to Google for this project, but it is confirmed to be operating at 2.7GHz. The configuration is unlike anything offered we've seen so far from AMD, perhps suggesting another, very prominent vendor - and Google has also confirmed to us that the CPU does not sit on the same package as the GPU.[...]Google has collaborated with AMD to deliver a custom graphics core for the Stadia project. Again, details on the architectural make-up of the GPU have not been disclosed, but 10.7 teraflops of compute has been confirmed, delivered via 56 compute units. Based on those numbers, Stadia's GPU core will be clocked at 1495MHz or in that ballpark. Cloud server GPUs can be virtualised, their resources spread between multiple users - but Google has told us that this does not happen on the Stadia set-up, meaning the full 10.7TF per player instance.When asked whether Stadia employs the Vega architecture or the upcoming - and extremely mysterious - Navi, Google would not comment.

Citazione^^* The Stadia tests were carried out on a Google connection vs our Stream tests 'in the wild' on a 200mbps connection. However, the Stadia tests include display latency on a Pixelbook (which we cannot measure) and were also carried out via WiFi networking. Both of these factors will add additional latency, while our Stream demo tests were carried out via a LAN hook-up to the router.** The '15mbps' mode is a simulation mode offered to developers, designed to mimic response on unstable connections. Image streaming takes a hit also, in terms of both resolution (1080p becomes 720p) and quality.*** This comparison stacks up overall measured latency end-to-end, with the local machines running on an LG C8 OLED display with game mode enabled, adding 21ms of lag. The Pixelbook display's latency is unknown.
CitazioneIf you have a very wide internet connection, Stadia supports 4K video at 60 frames per second with HDR support. However, based on conversations with Google, we expect that 1080p streaming is more likely to be the norm on connections with around 25mbps of bandwidth. Stadia will go lower, dropping down to 720p60 with connections in the region of 15mbps - but having seen it in action with an artificial cap in place, it's clear that fast action causes obvious artefacts on a large, living room display. Google itself considers this to be a 'worse case scenario'. The experience would likely hold up much better on a smaller screen, however.

Citazione di: Bluforce il 20 Marzo, 2019, 11:42:13Il sito ufficiale in Italia funziona, ciò dovrebbe significare che l'Italia fa parte delle nazioni che avranno Stadia al "day one".Da altre nazioni europee non si può accedere al sito.Riguardo l'input lag, c'è un tweet che gira con numeri ben diversi (inferiori e di molto) rispetto a quelli di Digital Foundry.Se non erro sono numeri registrati lì alla GDC, quindi sempre un ambiente ben "tutelato" dove potere fare prove di questo genere.Poi ci siamo noi dall'altra parte del mondo e le cose mi sa che cambiano...EDIT:Eccolo!https://twitter.com/krisgraft/status/1108121139815964673
