AMD - Anuncia Zen 2 ( Ryzen 3000 series) VEGA II, y otros

AMD inicio su presentacion del CES demostrando su nuevos chips RYZEN serie 5 y serie 3, llegando hasta 8 cores y 16 threads en "mainstream".


Y muestra desempeño aproximado de VEGA II, comparativamente similar a una 2080 GTX (1080TI+)



El nuevo 8 core 16 Thread de AMD también tiene un desempeño similar con el Core i9900K. Se rumorea que en promedio tiene una frecuencia estándar de 4.0. Ghz y 4.4Ghz de boost (igualando en cinebench al I9900k que tiene boost de 5Ghz)

Given that both processors have eight cores and sixteen threads, the benchmark results suggest that AMD is matching Intel's single-threaded performance, at least in this particular benchmark. Cinebench does respond well to AMD's SMT implementation, but the results are impressive nonetheless.

Possibly matching Intel's single-threaded performance is a watershed moment for AMD, as that type of workload has long been one of the few areas where the Ryzen processors lagged behind Intel's models. But that isn't all. Su also pointed out that the denser 7nm node allowed the Ryzen processor to consume less power, which ultimately equates to heat, than the Core i9-9900K.

The AMD processor pulled ~30% less power than the Core i9-9900K. That's a tremendous advantage over Intel's processors, which have gained a reputation for requiring high-end motherboards, power supplies, and coolers to extract the optimum level of performance. The Ryzen processors' impressive achievement means that it could be much cheaper to build full systems with AMD's Ryzen 3000-series processors, thus offering a similar level of performance while maintaining the value advantage.

Ryzen 3000 tendra un "nucleo compute" y un chip IO similar a EPYC 2.

Lo interesante es que AMD anuncio que las tarjetas madres podrán usar PCI EXPRESS 4 en el primer slot con un update del bios y con un procesador compatible.

No seria entonces obligatorio cambiar una tarjeta madre a menos que necesites todos los slots como PCI Express v4.

But after speaking with several motherboard vendors here at CES 2019, we've learned that many of them have successfully tested PCIe 4.0 on 300- and 400-series AMD motherboards, meaning that the feature could be enabled with a simple BIOS update, at least partially.

Our sources tell us that after unlocking the feature via a BIOS update, the older motherboards supply a PCIe 4.0 x16 connection to the first slot on the motherboard, but the remainder of the slots revert to PCIe 3.0 signaling rates. That's because any trace routing on the motherboard that exceeds six inches requires newer redrivers and retimers that support PCIe 4.0's faster signaling rates. That means the PCIe slot nearest to the CPU will easily support PCIe 4.0, while the other slots, including M.2 ports, will run at a PCIe 3.0 signaling rate.

Mas informacion de VEGA II

Today’s announcement is interesting in that it’s just as much about technology as it is the 3D chess that is the market positioning fights between AMD and NVIDIA. Technically AMD isn’t announcing any new GPUs here – regular readers will correctly guess that we’re talking about Vega 20 – but the situation in the high-end market has played out such that there’s now a window for AMD to bring their cutting-edge Vega 20 GPU to the consumer market, and this is a window AMD is looking to take full advantage of.

At a high level then, the Radeon VII employs a slightly cut down version of AMD’s Vega 20 GPU. With 60 of 64 CUs enabled, it actually has a few less CUs than AMD’s previous flagship, the Radeon RX Vega 64, but it makes up for the loss with much higher clockspeeds and a much more powerful memory and pixel throughput backend. As a result, AMD says that the Radeon VII should beat their former flagship by anywhere between 20% and 42% depending on the game (with an overall average of 29%), which on paper would be just enough to put the card in spitting distance of NVIDIA’s RTX 2080, and making it a viable and competitive 4K gaming card.

Esos de AMD se me hace que son contactados. Tanta tecnologia de repente es sospechosa...
