AMD Zen 8 Core 95W Summit Ridge CPUs Launching In October – Already Going Through Validation

AMD Zen 8 core high enthusiast Summit Ridge CPUs are allegedly slated for an October release on the new AM4 socket. A source close to AMD claims that the eight core Summit Ridge CPU dies have taped out in January and are running through testing and validation right now.

This is the second major milestone that we’ve heard about concerning Zen’s development The first being the tape out of the Zen core / microarchitecture back in 2015 and the second being the tape out of the eight core Zen based SOC in January. This means that not only has the core design been finalized, but development of the first product chip with Zen cores has been completed. This is the eight core 95W Zen SOC which will be coming to the desktop later in the year. AMD has several other Zen based SOCs – systems on a chip – in development. A 32 Core Zen server CPU, a sixteen core Zen HPC APU and a quadcore Zen consumer APU. All of which should be taped out sometime later this year.
The desktop FX CPUs allegedly feature a 95W TDP and eight high performance Zen cores with multi-threading for a total of 16 threads. Zen is said to have extremely competitive single threaded performance according to engineers with knowledge of the chip. Citing more instructions per clock than Intel’s Broadwell and just a smidgen behind Skylake. The 95W TDP if accurate indicates that indeed we’re looking at a very power efficient design. In contrast, Intel’s eight core i7 5960X is rated at 140 watts but then again we’re comparing a 14nm FinFET product with a 22nm chip so a delta is to be expected.

Teško osam jezgri plus grafiku nahranit s tim TDP-om, čak i na 14nm.
Anyway, moj 2600K strepi da ću ga prodat!

Neće oni imati grafičku (8 core koji dolazi Q4 2016), čisti cpu bi to trebao biti (tako je oduvijek najavljivano). Tako da taj prostor koji bi išao na igp ostaje za jezgre i manji tdp. Zato ne kužim spiku o soc-u (razumijem za ove s grafama ako će dolaziti sa hbm/hbm2 pa vjerojatno mora biti soc zbog toga). Lik je očito zabrijao

Iskreno, jedva čekam da izađe :)
Mogao bi i intel konačno prestat štancat i3 prevare ili im spustit cijenu za 50% tj na cijenu Pentiuma.

Što bi se se još moglo desiti je da ne moraš više Intelu plaćati porez na OC :)

Ili će i amd uvesti porez na OC po uzoru na intel :)

porez na oc :D isprika za nesposobnost :D

The latest rumor or should we say, update, comes from*BitsnChips*who have reported that AMD’s Raven Ridge APUs will be built by Global Foundries and packaged by South Korean Semiconductor company, Amkor. Amkor was the same company that packaged AMD’s Fiji GPUs (HBM+GPU+TSV). AMD will be using the GloFo-Amkor Duo to also package their next-gen Raven Ridge APUs that will utilize the next generation of HBM standard to deliver higher bandwidth to the faster discrete-class graphics chip featured on the SOC.

Citiraj:

It is exciting to know that Raven Ridge will be a 14nm design from top-to-bottom. Since these APUs arrive in 2017, we can expect the Polaris GPU architecture to be deployed on these APUs which delivers up to 2.5 time performance per watt improvement compared to current generation GCN architecture.

AMD’s Carrizo APUs currently deploy the same GCN architecture which is found on Tonga and Fiji and Bristol Ridge is expected to keep the same design. Raven Ridge which deploys the GCN 4.0 GPU design will not only help APUs perform faster in graphics performance but also much more efficiently. AMD’s first Polaris demo was of an entry level chip which delivered great performance for a sub-40W design.

But with more graphics power comes more demand of bandwidth which unfortunately doesn’t provide a lot of bandwidth to faster graphics cores. Intel’s solution to feed higher bandwidth was faster eDRAM cache but AMD is deciding to go the HBM route. The HBM will act as fast DRAM which the GPU will have full access to. That’s the part two of the statement by*BitsnChips*who state that Amkor packaging AMD APUs is a hint that these are going to deploy the fast HBM DRAMs.

It’s not known what specific amount of HBM will be featured but a single HBM2 stack can deliver as much as 4 GB memory and 256 GB/s bandwidth. You can clock it up and down but the most entry level stack can still get as much as 128*GB/s. AMD’s HBM partner*SK Hynix*will begin production of 4 GB DRAMs in Q3 followed by 8 GB DRAMs in Q4 2016. They also have 2 GB but there’s no date issued how ever these low VRAM DRAMs sound most ideal for Raven Ridge APUs.

Regardless of the amount of VRAM, the bandwidth increase will be more than enough for the dGPU on board Raven Ridge and the 40% IPC increase just from the Zen cores will lead to a huge performance gain on AMD’s next gen APUs. Theperformance*of AMD Raven Ridge is expected to reach or even exceed the levels of Xbox One and PlayStation 4 performance due to better CPU, GPU and memory architecture. The Raven Ridge APUs will hit the AM4 platform and will be exciting to see how AMD handles these high-performance mainstream / consumer APUs when they launch in 2017.

sick :) jedva čekam vidjet te APUe.

AMD Zen ‘Summit Ridge’ CPUs and Intel ‘Kaby Lake’ CPUs Spotted in AIDA64 Changelog

AMD’s AM4 Platform Details Leaked: µOPGA Based Socket with 1331 Pins, 140W Max TDP

Uglavnom sažetak prvog linka - zen je "on track" tj. čini se da ide na vrijeme
Drugi link - Imat će više manjih i zgusnutijih pinova

Mislim da bi uskoro trebale početi curiti info i slike AM4 matičnih

1331 pin, odmah kreću nagađanja o tome zašto. 4-kanalna memorija, dual-socket... :D

Manuel, bilo bi lijepo da tu i tamo ubaciš izvorni članak. Znam da je vjerojatno wccftech tvoj prvi izvor, ali neka i oni koji su iskopali informaciju budu prepoznati. Kao Bitsandchips.it koji su mali, ali izgleda imaju svoje izvore. Možda dobiju nešto od dva-tri klika. Samo prijedlog, nhf.

Vrlo vjerojatno ce biti 4-kanalna memorija ako se radi o high end segmentu jer upravo zbog toga ce moci parirati Intelovim procesorima. Za dual socket cisto sumnjam iako je i to moguce.

Hands-on Review & Overclocking Athlon X4 845: Cheap Carrizo Without IGP

Vidi se da ima bolji IPC:

Citiraj:

Can be seen, at the same clock in both benchmarks, the Athlon X4 845 excels between 3.5 - 11% of X4 860K depends what benchmarks and scenarios run. Roughly, this corresponds to the estimated core AMD estimates that the excavator will increase 4-15% depending on the type of workload it.

Ali ima čudne gaming rezultate (vjerojatno zbog manjeg L2 cache). Oni su testirali samo GTA, ali ovaj neki youtuber je više

Efikasnost je poprilično bolja od steamrollera, a imaju i zanimljiv test novog coolera u toj recenziji.

Inače tko ne zna, taj carizzo navodno nije ni planiran za izdavanje na desktop (fm2+), jer je navodno najefikasniji do TDP 35w. Onda je slučajno uletio taj 845, ali je evidentno da je to prenamjenjeni mobilni procesor. Stariji tekst:

Citiraj:

The goal of Excavator, as we were told at the time, was to develop a series of big steps into improving the efficiency of the base Bulldozer microarchitecture through high density libraries, better metal stacks in production, more on-chip analysis to save power, more power planes to regulate those chances and everything in-between. We were told we wouldn’t see the Excavator core on the desktop in its desktop form because the design focused on the 15W-35W power window, rather than the 45W+ on the desktop.
Fast forward to today and there seems to be a slight reversal here. The new AMD Athlon X4 845 is a pair of Excavator modules in a desktop package, designed to slot right in where the Steamroller design through Kaveri has been sitting for a couple of years. Why the change? And why a single SKU at 65W, way off the 15W-35W range quoted as 'ideal' back at the Tech Day?

One thing that was made perfectly clear in AMD’s briefing on the new Athlon was that this is not a performance part – due to the nature of Excavator the new CPU would be purely an efficiency play, allowing customers to take advantage of the latest architecture in the desktop if they didn’t need the full-fat performance.

Citiraj:

With the new Athlon, the fact that there is no graphics part to the FM2+ processor does raise several questions. Is this a new die specifically for the Excavator on desktop, which might run into the tens of millions of dollars to produce, or is it repurposed mobile silicon put into a desktop package. Instinct tells us it’s the latter, perhaps better binned parts to show that the core can do 3.8 GHz at 65W, but at the expense of the integrated graphics, or due to production issues the integrated graphics on die are unusable. One of the interesting things is also the L2 cache situation, because the Excavator modules in Carrizo were designed with 1MB of L2 per module, rather than the 2MB of L2 cache per module in desktop Kaveri. This is somewhat balanced by the larger L1 data cache in Excavator, but because there is no L3 cache either, it has to rely on other Excavator enhancements (better prefetch, wider prefetch windows) in order to bring it up to speed.

The PCIe 3.0 lanes are also at x8, which is another mobile limitation rather than the result of the PCIe root complex being half-disabled.

Piše se na bugu da ce zen po IPC-u biti kao Haswell sto nije lose ako ce biti jeftiniji.
Taman ce tada Intel izbacit Kabylake koji je navodno tu negdje sa Skylakeom po IPC-u.

Koliko sam čuo,na computexu će uz Polaris biti prototip Zena.
Just so you know 😊

A gdje si čuo?

Mislim da neće. Spominjao se bristol ridge. I to nije sigurno dali se uopće odnosi na desktop verziju

AMD Zen will favourably compete with Intel Skylake

Ništa pretjerano novo, par novih izjava iz amd-a danih na nekoj konferenciji za novinare u Australiji

Citiraj:

“Zen will compete with Intel on performance, power and specifications – not just price,”

Citiraj:

Taylor said that AMD had perhaps lacked focus but its new CEO Lisa Su (October 2014) had laser focused the company on becoming a high-performance computing and graphics company - products like Zen were the result of that. Of the company 9000 employees, more than 7000 were ‘engineers’ and its main areas of focus were:

Gaming
Immersive platforms (VR)
Datacentres

Citiraj:

“For the first time since I have been at AMD, I can say with absolute confidence that AMD has the products and strategies to change any negative perceptions customers may have had. AMD has moved ‘upstream’ with its support from HP in the new business class Elitebook and believe me we will get into premium products like Dell XPS, Lenovo Yoga, and HP Spectre and many more,” he said.

While everyone expects a PC to do everything AMD had spent a lot of R&D making sure it supported things like USB 3.1 (USB-C and Thunderbolt), M.2 SATA and NVMe as well as addressing power and cooling issues. “Our new Wraith coolers are getting rave reviews – you don’t need an expensive third party cooler and more,” he said.

“By the end of the year, AMD will have moved on, to both its Zen CPU core as well as the Polaris graphics architecture. We are far closer to Intel than ever before – you always need a number two to keep them honest,” he ended.

WCCF naravno ima još opširniji recap događaja, nadodan uz masu starog infoa. Međutoa ovo nisam prije vidio (price range):

Citiraj:

AMD’s plan, our sources tell us, is to price high core count parts very competitively. Undercutting Intel’s mainstream CPUs by offering more cores with competitive – Broadwell level – single threaded performance at Intel’s mainstream i5 and quadcore i7 price points. Essentially offering Haswell-E / Broadwell-E comparable parts in the mainstream $400-$150 segment. A space that’s currently occupied by Intel’s mainstream quadcore I7, i5 and dual core i3 CPUs .
