ZEN listos para pruebas y sus reviews [por gente del foro]

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.

Estos chipsets son de 'borron y cuenta nueva'. Solamente son para el nuevo zocalo AM4 el cual solo sirve para modulos DDR4, asi que AMD no dara soporte a DDR3 de manera oficial, quiza algun fabricante saque alguna version hibrida DDR3/DDR4, pero el controlador de memoria para DDR3 seguro seria mediante un chip externo. Los CPUs/APUs ZEN, su controlador de memoria es solo para DDR4.

Asique no veo raro preguntar si serviran ddr3

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:

Es solo un rumor, aunque como casi todo lo que esta pasando con Zen , pero ojalá sea verdad. Tengo ganas de montarme un ordenador rojo.

Englobará SR3,SR5 y SR7. De menor a mayor gama, supongo que parecido al i3, i5, i7

Un aspecto importante para la refrigeración, para evacuar calor.

Así de entrada para htpc y los tdps que se rumorean igual zen no es la mejor opción .

No hombre. Tú eres un tipo aplicao . Pero como recuerdo mi experiencia con un 4790k en una Aerocool ds silence . Yo quiero hacerme algo parecido para el camping, primando el consumo y el espacio ante todo y queria que fuera un pc rojo, pero los tdps rumoreados de zen me asustan un poco

Si tengo que cambiar placa y cpu no quiero gastar más de 300...., la memoria RAM valdrá? o tendría que cambiarla?

Tengo un FX6300 vago vago que no sube de 4,1GHZ

Por otro lado, lo único que sabemos de SR5 y SR3 es que estos estarán entre los 200 y 300 dólares, y como no, al igual que SR7, tendremos diferentes variables, incluso una gama preparada para el overclock, como ya vimos en las “black series”.
