Parece ser que veremos el chip X370 'trabajando' para enero del 2017, junto con la primera muestra del CPU Zen, esto dentro del evento CES 2017 [Feria de Tecnologias al consumidor en estados unidos] alla en la Vegas, Nevada. Despues del evento se comenzaria la venta al publico, en febrero segun el calendario de AMD, la cual a pedido acelerar la produccion para poder satisfacer la distribucion global a las tiendas.

Cosa curiosa, la tarjeta madre con este chipset de alto rendimiento X370 se comenzara a vender en diciembre de este año. Esperemos no se requieran de actualizaciones de UEFI de ultima hora para dar compatibilidad al CPU ZEN.

digitimes.com escribió:Following the releases of its Bristol Ridge-based desktop processors in September 2016, AMD's Zen-based CPUs and its corresponding high-end X370 chipsets will make their arrivals at CES 2017 in January. To achieve a smooth transition, AMD has begun adjusting product prices in order to accelerate inventory digestion. However, since Zen-based products are unlikely to start mass shipments until after February, they are unlikely to start contributing profits until the second quarter 2017, according to sources from the upstream supply chain.

..

Zen-based processors will be manufactured on Globalfoundries' 14nm FinFET process, featuring an eight-core-16-thread design. AMD will initially release Zen-based high-performance desktop processors (Summit Ridge), while one for notebooks is scheduled to launch at the end of second-quarter 2017.

The high-end X370 chipsets will be launched at CES 2017, while mainstream B350 and low-end A320 will be unveiled later. X370-based motherboards will begin shipments in December.

ASMedia, which is designing and manufacturing chipsets for AMD's processors, is also expected to see rising revenues with the releases of the new CPUs.

Segun lo informa wccftech. ZEN [¿Opteron?] para sistemas empresariales vendra con varias instrucciones para el tema de seguridad, mas un sistema de verificacion SHA por hardware, que emplea un procesadro ARM integrado.

Para la seguridad basada en la encriptacion usara las instrucciones SME [encriptacioon de la memoria] y SEV [encriptacion en el sistema de virtualizacion]

Usman Pirzada, wccftech.com escribió:AMD x86 Zen Architecture Will Implement Game Changing Encryption Features Such as SME, SEV and HW Based SHA – Not Present In SkyLake or KabyLake

AMD Zen features SME (Secure Memory Encryption), SEV (Secure Encrypted Virtualization) and hardware based SHA powered by a security co-processor

There are two main features that I will be talking about in this article, alongside a third feature which in combination will make Zen a much sought out processor for the Enterprise sector. The first two are called SME and SEV, which stand for Secure memory Encryption and Secure Encrypted Virtualization. The third one is hardware based SHA. As I have mentioned before, at this moment, no competing Intel architecture has any known features to rival these. At the time of release, Zen will primarily compete against Skylake and Kaby Lake based processors, both of which lack the aforementioned features. It is not until Cannonlake and Coffe Lake that any semblance of parity is expected to be present between the two platforms – and even then it won’t be complete.

All of this magic will happen, courtesy a “Security Co-Processor” that AMD has included inside of the Zen chip. Before we get into any explicit details – let me explain what all of this fuss is about. Let me explain this by giving you the example of this very publication. WCCFtech is hosted on a VPS based platform that scales according to the traffic we get – in other words, it’s hosted on the cloud. This means that we don’t have to pay for server resources we aren’t using and aren’t left stranded when traffic spikes. When we say it’s hosted on the cloud, what is actually happening is that we are serving our website via an instance of a virtualized server running on a physical server. This virtualized server can scale up or down (depending on the limits of the physical server) dynamically, according to the demand of the client and is hosted primarily in the RAM.

[..]

This is the holy grail of cloud computing (and security conscious individuals) and as the name states, will allow end users to encrypt the entire instance of virtualization. Not even cloud providers (who have physical access to the servers) will be able to carry out any malicious actions against their clients, if they were so inclined. For all intents and purposes, the data of consumers would be well and truly safe.

Zen will also contain hardware SHA – which means it’s going to offer significant performance improvement over previous iterations of AMD architectures and even Intel offerings! As far as we know, hardware based SHA will not be present in Intel offerings till Cannonlake arrives and we have already listed the major disadvantage of SGX – it cannot be virtualized. So at the time of launch, Zen processors will be the only competitive x86 chips around rocking hardware based SHA (and the accelerated performance that comes with it) as well as the security co processor powered SME/SEV security features. It remains to be seen when and if Intel will offer a competing solution to SEV.

En los foros de ANANDTECH aparece informacion de una supuesta fuente de mucha fiabilidad que menciona sobre unas versiones de muestra de ingenieria del procesador, las frecuencias de trabajo para las versions de 8 nucleos y de 4 nucleos ZEN.

Summit Ridge [8C|16T] serian 3.15|3.3|3.6GHz
Raven Ridge [4C|8T] serian 2.9|3.1|3.4GHz

AMD POLARIS escribió:Hi all! I went into the forest recently and birds have tweeted something again. They spoke about 2 new SKUs that have just hit the post-boxes of the mainboard manufacturers. They are both A0 revisions and Engineering Samples, so there is no improvement since my last post.

The first one is an 8-core design with AMD's HT implementation and it's got a 3150 MHz base clock, it's all-core turbo is 3300 MHz and the max turbo for 1 core is 3600 Mhz. Yes, here are some improvements regarding the previous 8-core SKU under the same TDP envelope.

The second SKU is a 4-core one with AMD's HT. It's got a 65W TDP and the base clock is still 2900 MHz. All-core turbo is 3100 MHz, max turbo is 3400 MHz. I don't know if it's only an SKU for testing mainboards or something is not okay with the clock-wattage correlation. I mean on higher clocks the 4-core SKU steps into the 95W TDP envelope, AMD can't keep the wattage low. Maybe GloFo's 14nm process needs some maturing... Frankly I don't have a clue what's in the background.

Retail AM4 mainboards are under production. The whole platform will be ready to have a paper-launch at the end of the year with a real availability in February of 2017. Performance wise the Zen uarch will be around Haswell and Broadwell (except for FMA), it seems it won't catch Skylake clock for clock. It's not a big deal, but if the clocks can't go higher until the start it won't fulfill the expectations. And we all know that expectations in this case are very high...

Supuestas pruebas bajo Blender para ver el rendimiento de los nucleos Zen en el render. Esto bajo una unidad de pueba de ingenieria ZEN.

Cita:New AMD x86 Zen Blender Benchmarks Surface – Show Equal Performance To A 10-Core Intel Xeon E5 Chip.

A benchmark of AMD’s upcoming x86 Zen architecture has been spotted on Blenchmark.com (a relatively unknown aggregate database for Blender tests). The test was spotted by this redditor and shows some very impressive performance if we take the result at face value. Unfortunately, the processor has no identifying information along with it so it is impossible to determine which variant of AMD’s Zen processor the results represent.


New blender benchmark of an AMD Zen CPU spotted in the wild – possible Naples variant

AMD’s philosophy with the upcoming Zen architecture is one of complete uniformity. The company will be shipping variants that scale (initially) from 8 cores for Summit Ridge and up to 32 cores for the Naples processor. While the result is undoubtedly legitimate in nature, the lack of identifying information makes it very hard to judge the performance. To put it simply, it is very impressive performance for an 8 core but only decent performance for a 16 core and above.

The processor is listed as “AMD Engineering Sample” and is several positions above the Core i7 6900k – the octa-core processor the Summit Ridge variant was originally tested against. It manages the Blender run in 69 seconds – which is exactly the same performance as an Intel Xeon E5 2680 v2 processor. This is a chip that has 10 cores! It is marginally faster than the Xeon E5 2650 v2 – which is an 8 core processor. Both of these feature relatively low base clocks (as is usually the case with Xeon chips) of 2.8 Ghz and 2.6 Ghz respectively.

The test date is approximately the same time that the official demo for Zen was shown but since we have evidence of Naples being ready for testing quite a while before that, this does not prove anything. If this is indeed the 8 core chip, then its performance exceeds all expectations and blows away the competition. The only thing that will remain will be the price point and as you can expect a significant premium over AMD’s usual value philosophy.

On the other, if this represent a Naples variant, it fits more or less within the performance we were expecting. Since Intel has had a significant process advantage over AMD for quite some time now I do not expect Zen to beat Intel core for core, clock for clock. However, we do believe that the Sunnyvale manufacturer will give Intel very real competition in terms of performance per dollar – which is all that gamers are usually interested in.

It is my belief however (caution: opinion) that this particular result represents a server class chip, i.e. Naples. This is because the benchmark was conducted in Windows 2008 Server R2 64 bit edition – an odd choice for a desktop variant. One would expect the Summit Ridge CPU to be tested on the latest OS: Windows 10. Since we do not know the clocks at this point and engineering samples are usually clocked low, this does go on to show that AMD can make a very big comeback in the server sector (if the price point is right). I am not going to go into any further speculation regarding the results since our readers can take care of that themselves and will end on the following note:

Como sea, sin duda la nueva nomenclatura sera en referencia a la adoptada por intel con su 'coreiX' [i3, i5 e i7], y no es mala idea, asi sera sencillo identificar la gama del procesador y la generacion.

Lo interesante es la lista de precios y como esta distribuido el numero de nucleos en Summit Ridge

SR7 8nucleos/16hilos [USD$500 y USD$350]
SR5 6nucleos/12hilos [USD$250] y
SR3 4nucleos/8hilos [USD$150]

Con lo que seria la posible respuesta a la pregunta: ¿Y los modelos de 4 nucleos?

Si esos son los posibles precios, almenos los sugeridos por AMD, creo que se tendria competencia contra Intel costo/rendimiento.

A esto y de regreso a la arquitectura SMT, que es en la que se basa ZEN.
TRASTARO escribió:¿Una nueva familia de tarjetas Radeon?

AMD ha visto de registrar el nombre Ryzen para uno de sus productos GPU.


Actuales noticias indican que RyZEN; nombre de marca ya registrado por AMD; podria ser el nombre comercial con el que salgan los CPU ZEN el proximo año, con lo que AMD dejaria atras el nombre FX. De esta manera tendriamos los.

Ryzen SR3, Ryzen SR5 y Ryzen SR7.

Asi mismo, AMD esta registrando otros nombres como marcas, entre ellos el de THREADRIPPER, el cual por el mismo nombre hace pensar que se refiera a lo que era el Hyper-Threading, es decir, las tareas multi-hilo.

Khalid Moammer, wccftech.com escribió:AMD Confirms Multiple Zen + CPU Core Architectures Planned Over 3 To 5 Years

AMD’s CEO Lisa Su confirmed that the company is working on several generations of CPUs to succeed Zen which are set to arrive over the next 3 to 5 years. These future CPU cores and microarchitectures were referred to by the CEO as “Zen+” and Zen follow ons.

These high performance CPU offerings are meant to satisfy the needs of the market at the high-end following the introduction of the first Zen based CPU products next year. Zen is no doubt one of the most hotly anticipated AMD products announced for 2016. It signals the company’s re-engagement and re-entry into the high-end CPU segment with a brand new CPU microarchitecture following a near complete absence of participation from the company in that market for what now amounts to approximately half a decade.

AMD’s Long Term Zen CPU Roadmap : One Robust Platform, Several Generations

Su confirmed at the 19th Annual Technology, Media & Telecom Conference that the company is working on several generations to succeed Zen, these “Zen+” or “follow ons” will continue to drive the performance and longevity of the platform over a timespan of three to five years.
