AMD's Zen Is Twice As Fast As The FX 8350 - Zen 8 Core CPU Die Shot Revealed

AMD has revealed that Zen volition have double the functioning of the FX 8350 and will trade blows with Intel'due south eight cadre i7 5960X Extreme Edition. Non only that but a die shot of "Summit" what will exist the basis of AMD's long awaited next generation high performance FX Zen CPUs has finally been revealed.

AMD'due south Zen viii core enthusiast course Meridian Ridge CPUs are reportedly slated for an October launch on the company's brand new AM4 socket based desktop platform. These next generation FX CPUs will include eight, six and quad core configurations. Which will deliver double the performance cadre for cadre of AMD'due south current desktop FX 8300 and 6300 serial lineup.

AMD's Zen 8 Core CPU Delivers Double The Performance Of The FX 8350, A Real Challenger To Intel'south i7 5960X Farthermost Edition

AMD has finally published additional performance figures for Zen across the 40% IPC improvement over excavator that the company talked about terminal year. The forty% IPC uplift figure represents the architectural performance per clock improvement of Zen vs AMD's concluding CPU architecture, code named Excavator. And while comparison the architectural capabilities of zen to Excavator may take been informative, it doesn't offer a direct real-earth product to production comparison. Thankfully, we do finally have direct real-world performance figures for Zen.

Compared to AMD's "Orochi" quad module, eight core die powering the FX 8350, the Zen based desktop Summit Ridge eight core CPU delivers double the functioning in Cinebench R15. This means that a single Zen core is in upshot equivalent to two Piledriver cores in functioning, which is incredibly impressive. This dramatic performance difference comes from the pregnant architectural functioning per clock improvements in addition to Zen's simultaneous multithreading capability.

it's of import to remember that AMD's latest Orochi dies characteristic Piledriver cores rather than Excavator. Excavator cores are roughly fifteen% faster per clock than Piledriver This in turn puts Zen at a lead in excess of 60% vs Piledriver in terms of performance per clock. Doubling the operation of the FX 8350 puts Zen in direct competition with Intel'southward eight cadre i7 5960X.

Run across Tiptop, AMD's Eight Core Zen CPU

Forth with the performance numbers that we only discussed above, AMD has too published a wafer shot of the company's upcoming viii core "Elevation" die. This die shot represents the very first at the foundation of AMD's upcoming Zen FX CPUs. Shout out to Thomas Ryan of Semiaccurate who spotted the wafer shot.

The Summit die is rectangular in shape. It houses ii calculating clusters placed at the opposite ends of the fleck. Each computing cluster is comprised of four Zen cores. This rounds upward to a full of eight Zen cores in each die. Each core in a given cluster of four shares L3 cache with the other three adjacent cores in the same cluster. In terms of other logic we can also see what appears to a DDR4 PHY placed in the lower left corner of the dice. In add-on to the DDR4 memory controller the Elevation SOC also includes an integrated northbridge as well as numerous I/O logic.

We published an exclusive report last year detailing AMD's plans to introduce its Zen based FX CPUs subsequently this year and Zen based APUs in 2022. We as well broke downwardly details almost Zen CPUs, APUs, AM4 motherboards and the features of AMD'south next generation platform which haven't been fabricated public nonetheless. And so we would highly recommend that you go check out that written report if you're interested in finding out more about Zen.

Desktop Zen CPUs are part of the "Summit Ridge" family. Which is going to include a total lineup of high-end Zen based FX CPUs that will characteristic "high cadre counts" and are gear up to compete in the "enthusiast" segment, AMD revealed concluding year and reiterated again earlier this yr.

AMD announced Zen for the very first time at its Financial Annotator Day last year. That's when the company touted the xl% improvement in instructions per clock versus its latest high performance core code named Excavator. However, earlier this twelvemonth President and CEO of the company Lisa Su announced that Zen is actually exceeding initial expectations and that it's now on track to attain an IPC uplift that'south greater than 40%.

AMD Preisdent & CEO Lisa Su - Q4 2022 AMD Earnings Call Transcript
Our Zen-based CPU development is on rails to reach greater than xl% IPC uplift from our previous generation and nosotros're on schedule to sample afterwards this year.

In customer calculating, our opportunities to regain share in 2022 volition be driven by our pattern win momentum, connected progress expanding into
the commercial market, and reentering the high-performance desktop market place late in the yr with our Zen-based Summit Ridge CPU.

AMD announced that it will launch an entirely new line-up of FX CPUs later this year on a brand new platform. These Zen FX CPUs are what AMD refers to as "Summit Ridge". The new platform will include a new socket with DDR4 memory support. AM4 will also support upcoming Bristol Ridge APUs. This is in effort to unify all of AMD's desktop computing products under one roof which will requite users a wider range of option and a directly upgrade path from APUs to CPUs.

AMD'south Most Important Proudct In More than Than A Decade - A CPU Architecture For Gamers, Professionals & The Datacenter

Zen has been ane of the most hotly anticipated AMD products for every bit far every bit I can retrieve. It'southward the company'southward first effort to compete at the loftier-finish, enthusiast, CPU marketplace since its last effort five years agone. Zen breaks new footing for AMD in many ways. It's the company'southward first truly innovative next generation CPU architecture since the Phenom . Information technology's also the very first CPU for AMD to actually be on parity with Intel in terms of process technology since the days of the original Athlon.

And so for the very first time in the market since the early 2000s AMD's CPU products won't exist at an inherent disadvantage due to Intel'southward process lead. From an architectural point of view Zen is a brand new clean-slate blueprint that'southward been led from the get-go by achieved CPU architect Jim Keller. The very same man that brought us the original Athlon XP and Athlon64 processors. The almost competitive CPU products in the history of the company.

And so it seems all the stars are lining up for AMD this year, which has seen its fair share of struggles over the past several years. All the components are in that location to make Zen a successful product.  It has taken more than a decade, only it'due south finally here. An AMD product that can actually challenge Intel'south highest performing Extreme Edition CPUs. It's almost unfathomable at first thought, afterward all we all grew accustomed to seeing Intel's enthusiast CPUs go uncontested for the longest time.

Zen is AMD's biggest long-term technology bet and 1 of the visitor'southward largest engineering efforts in recent retentiveness. AMD's President & CEO Lisa Su stated that this year's products, culminated in Zen and Polaris, correspond company's nigh competitive roadmap in more than than a decade.

AMD President & CEO Lisa Su – Q4 2022 Earnings Telephone call

"Nosotros remain focused on completing our strategic work around three key growth pillars. First, in PCs, even in a declining overall market, nosotros believe we tin can regain customer compute and discrete graphics share for the year, driven by gaming, VR, commercial, and our almost competitive product roadmap in more than a decade.
Nosotros have clear opportunities to regain GPU share in 2022 based on the functioning per watt of our new GPUs and software leadership. Before this quarter at CES, we announced our new Polaris GPU compages, which we expect to begin shipping in the middle of 2022."

The microarchitecture taped out dorsum in 2022 and products are on track to launch later this year on the desktop. Nonetheless, nosotros know that AMD is working on far more than just loftier performance desktop CPUs. The company has had 32 Core Zen server CPU, a 16 cadre Zen HPC APU and a quadcore Zen consumer APU all in the works for several years.

AMD's President & CEO Lisa Su confirmed earlier this month at the company'due south annual meeting of shareholders that Zen is has been running in the visitor's labs for sometime and is showing results that exceed expectations. She besides confirmed that Zen will begin sampling this quarter.

The AIDA64 benchmark added support to Zen based Summit Ridge every bit well as Raven Ridge FX CPUs and APUs terminal yr. Raven Ridge will succeed Bristol Ridge and will be the showtime generation of APUs to feature Zen, while Bristrol Ridge will exist a refresh based on the 28nm Excavator core. Several leaks accept also revealed that AMD is working on several Zen APUs with big discrete class congenital-in GPUs and high bandwidth memory.

On the server side AMD is preparing Zen based CPUs with up to 32 cores and 64 threads. That's four times as many threads as AMD's electric current highest end server offering. A very pregnant jump that's going to play a crucial role in giving Zen the competitive edge it needs in servers. A market that Intel has virtually monopolized over the past several years.

AMD's Zen Core Under The Microscope

14nm FinFET Procedure

Samsung'south 14nm FinFET process which Globalfoundries has licensed is going to exist the basis of all of AMD'south side by side generation CPU, APU and GPU products. The company'southward Chief Engineering science Officer Marker Papermaster fabricated the announcement terminal year that the 14LPP procedure - Samsung's high performance 14nm process - will be leveraged beyond all of AMD'southward futurity products.

The 14LPP process features 3D finfet transistors and significantly smaller gates compared to 28nm. Chips manufactured on the 14LPP process take more than than double the density of 28nm. Additionally, 14nm FinFET transistors are capable of significantly faster switching speeds. Products designed for the process will exist able to attain much college frequencies than the same designs on 28nm. The procedure also delivers considerable power savings, substantially cut ability consumption by one-half.

Higher Integer And Floating Point Throughput & Lower Latency Enshroud Sub-Organisation

AMD's Linux Kernel patches which have been a rich source of information near Zen. The patches revealed and then much about the inner-workings of Zen to the betoken where nosotros are really able to visualize the high-level design of the core. If yous're interested in all the nitty gritty details about what the core is capable of I'd highly recommend our exclusive in-depth analysis of Zen'due south micrarchitecture.

Wccftech.com Rendition Of Zen's Loftier-Level Design Based On The AMD Linux Kernel Patch

Above you tin can come across a visual representation of Zen on the right in comparison to AMD's Steamroller CPU core. Which is the third generation based on the Bulldozer design and is pretty much identical from a high-level standpoint to Excavator, the fourth and final Bulldozer based core. There are several fundamental differences betwixt Zen and the bulldozer family.

AMD has done away with the CMT - clustered multi-threading - concept in favor of a more than traditional SMT - sumultaneous multi-threading - design. This means that each Zen core volition exist able to execute two threads simultaneously. One main, very high throughput thread and i secondary thread that can be used opportunistically.

In contrast, each Bulldozer module tin can execute two equal threads. This is achieved through two dissever integer clusters with a single front-terminate. This approach saves area versus edifice two separate cores and delivers two high throughput threads. Even so, there are advantages that Zen's SMT implementation holds over the Bulldozer CMT implementation. For one it allows AMD to build a single larger integer cluster with significantly higher single threaded functioning. Another advantage with this approach is that it still leaves room for opportunistic savings in area and ability.

The final result is similar overall throughput when we await at both treads of each SMT core vs both threads in each CMT module. Nevertheless, the SMT style cadre volition deliver significantly college single threaded performance. Furthermore, because each Bulldozer module houses two integer clusters and a single floating point unit it was ever been very integer heavy. Each Zen cadre on the other hand includes ane large integer cluster and one large floating signal unit, making it an inherently more balanced design.

Single Core Peak Decode Rate	iii instructions	iv instructions	eight instructions	iv instructions	4 instructions
Dual Core Peak Decode Rate	6 instructions	4 instructions	8 instructions	8 instructions	8 instructions

A lot of the applied science effort around Zen has also been done to address one of Bulldozer's major flaws. Bulldozer and Intel'south Sandy Span - and subsqeuent Intel architectures including Skylake - had equally deep pipelines to achieve high clock speeds. The deeper the pipeline the more latency that blueprint volition exhibit. Specially when it comes to co-operative misprediction errors, which are quite mutual in modern pipelines.

The latency that results from branch mispredicts are quite significant. To combat this issue Intel introduced a micro-op enshroud with Sandy Bridge. It worked to considerably reduce mispredict penalties and it was the principle reason why Sandy Bridge had much improve single threaded performance as opposed to Bulldozer. The latest Linux Kernal patch also as a group of AMD patents bespeak that the company has implemented a like solution in Zen.

AM4 : AMD'southward Brand New Unified Socket

In our exclusive report we published last year we shared an sectional look at the features that Summit Ridge products and the new AM4 platform will bring to market place later this yr. For starts Summit Ridge CPUs will include models with eight, six and iv Zen cores. Iv cores beingness the lowest core count Summit Ridge CPU AMD is going to sell. All CPUs will include the company's new platform security processor, PCIe iii.0 back up, dual aqueduct DDR4 memory controllers, copious amounts of L3 cache and updated storage features.

John Taylor, head of worldwide marketing at AMD, revealed that the company has poured a lot into R&D to brand sure that information technology's AM4 platform and Zen CPUs support the latest & greatest features. He confirmed that USB 3.one, M.2 SATA and NVMe will all be supported. He besides said that a lot of effort has gone into ensuring that Zen delivers the best possible feel to users. This includes thermals and acoustics. "Our new Wraith coolers are getting rave reviews – you lot don't need an expensive third party cooler whatever more" he said.

Bringing this to a shut, information technology's clear that AMD's is doing a lot of things right with Zen. Pushing IPC and power efficiency to where they need to be. Building a comprehensive modern platform and bringing much needed updates to the feature-gear up. Creating an attractive value proffer for desktop users, servers and notebooks. All the ingredients to brand Zen a success are here, all that'due south left is for AMD to execute and deliver. The mere prospect that enthusiasts may actually have AMD CPUs equally a worthwile pick again for the first time in a decade come up this October is refreshing. And maybe, just perhaps, nosotros'll finally be able to say "AMD's back".
