If you are an enthusiast that recently upgraded from Windows 10 to Windows 11 and have noticed some performance degradation, you’re not alone. Although we’re not sure why these issues didn’t rear their heads earlier during the Windows Insider testing phase, AMD confirms that its Ryzen and EPYC processors are affected by two performance-robbing bugs. The first issue involves L3 cache latency, which can increase by 3x compared to the same system running Windows 10. As a result, applications that are “sensitive to memory subsystem access time” could be affected, resulting in a performance hit of 3 to 5 percent in some applications. However, AMD notes that the performance... Read more...
Since 2020, Netflix has been able to serve up 200 gigabits per second (Gbps) of TLS-encrypted video traffic from each of its servers, but there is now a path to doubling that amount to 400Gb/s. Andrew Gallatin, a senior software engineer at Netflix, outlined how the streaming service has been able to achieve the feat using a combination of AMD's second-generation EPYC "Rome" processors and various software optimizations. That's a lot of bandwidth, and incidentally, it comes right as Netflix eyes an entry into video game streaming. Game streaming was not mentioned during the presentation, though it is an interesting aside to this latest effort. AMD's EPYC 7502P Rome processors provide the big... Read more...
AMD's next round of server processors are going to be EPYC beasts, if recently leaked documents end up being legitimate. These supposedly official documents outline some of the characteristics of AMD's next-gen EPYC processors based on its upcoming Zen 4 architecture, including the SP5 socket design they will slip into, and the possible max core count. As things currently stand, AMD's EPYC 7003 series based on Zen 3 (codenamed Milan) scale to 64 cores and 128 threads of raw compute muscle. That is the core and thread configuration found on the company's EPYC 7713/7713P and 7763 processors, with boost clocks maxing out at 3.675GHz for the former and 3.5GHz for the latter. Looking ahead to AMD's... Read more...
Bergamo is a city in Italy, located northeast of Milan. It might also be the codename for an upcoming 128-core/256-thread EPYC server processor based on AMD's Zen 4 architecture, if the latest rumor is to be believed. If true, the chip would represent a spirited attempt by AMD to claim more data center market share from rival Intel. Does it actually exist, though? Well, not right at this moment. It might be on AMD's internal roadmap, though, destined to arrive sometime after Genoa (also Zen 4) and before Turan (Zen 5). Or perhaps it was planned or discussed at some point, but then AMD later decided to shelve those plans, at least for the time being. That's the problem with leaks and rumors—sifting... Read more...
Today, Google announced a new family of virtual machines called Tau VMs, “optimized for cost-effective performance of scale-out workloads.” Furthermore, the Mountain View-based company has partnered with AMD to create the first VM in the line, the T2D, which is powered by 3rd Gen EPYC processors. In a blog post today, Google Cloud Infrastructure SVP Urs Hölzle and VP and GM of Compute at Google Cloud June Yang explained that this partnership between AMD and Google is important for both performance and pricing reasons. They state that the new virtual machine in the lineup driven by Zen 3 “leapfrogs the VMs for scale-out workloads of any leading public cloud provider available... Read more...
AMD has been on a hot streak in the processor market since it introduced its first-generation Zen architecture in 2017. Its most recent iteration, Zen 3, is available across consumer (Ryzen), workstation (Threadripper), and enterprise (EPYC) product families, topping out at 64 cores for the latter two. AMD has delivered the goods on performance with its Zen families, but it has also offered more cores than Intel's competing Core and Xeon counterparts. Now, new rumors allege that AMD is on track to deliver another big performance boost with Zen 4, along with a leap in core counts. It's now alleged that at least one variant of the Zen 4 architecture will feature a stunning 128 cores, which would... Read more...
A reinvigorated AMD is making strides across the board, including the high-dollar data center segment where premium sums go towards the top silicon money can buy. Intel has historically dominated data center sales, but it can ill-afford to become lax—AMD just saw its its biggest sequential jump in data center market share in 15 years. The gain coincides with AMD recently revealing it more than doubled its data center revenue last quarter, which contributed to a strong three-month period that saw AMD rake in $3.4 billion in revenue, a gain of 93 percent compared to the same quarter a year ago. Its net income, meanwhile, grew 94 percent year-over-year to $555 million during the first quarter... Read more...
When we think of processors used in the enterprise market, Intel Xeon or AMD EPYC x86-64 families typically comes to mind. Intel has the lion's share of the market, with AMD steadily gaining traction ever since its Zen architecture birthed first-generation EPYC 7001 processors. However, Arm is also a player in this space with its Neoverse CPU architecture, which first debuted in 2019. Neoverse N2: Cloud-to-Edge Performance Greatness Amazon Web Services (AWS) deployed its and Graviton2 processor, while Ampere has made waves with its Altra; both processors are based on Arm's Neoverse N1 architecture. Today, Arm is ready to take the next giant leap in performance with the launch of Neoverse N2.... Read more...
AMD just launched its next-generation EPYC server processors, codenamed Milan, based on the company’s leading Zen 3 microarchitecture. The new EPYC 7003 series is an important milestone for AMD. The company has made significant in-roads in servers and data centers in recent years, and the arrival of the EPYC 7003 series brings with it significantly improved IPC and per-core performance, better multi-core scaling, and more flexible memory configuration options (among other new features), in a package that’s socket compatible with previous-gen offerings – existing EPYC platforms will support the EPYC 7003 series with a simple BIOS update. The biggest change with the EPYC 7003... Read more...
AMD is finally ready to take the next step in the rollout of its Zen 3 family of processors following the launch of Ryzen 5000 desktop and laptop families. Today, AMD announced that its third-generation EPYC processors would be officially announced on March 15th at 11 am ET, one week from today. On hand at the virtual press conference will be AMD President and CEO Dr. Lisa Su and Mark Papermaster, who serves as Executive VP of Technology and Engineering. Dan McNamara, SVP and GM of the Server Business Unit, and Forrest Norrod, VP and GM for the Datacenter and Embedded Solutions Business Group, will also be there during the presentation to talk about EPYC. Beyond those details,... Read more...
It has been interesting to see AMD and duke it out on the home desktop, the former with its latest generation Zen 3 architecture and the latter with Comet Lake (soon to be Rocket Lake). But that is not the only place these two chip giants tussle. The server space is an important battleground, and both are set to load up new artillery, models and specs of which have seemingly leaked out. Leaked information on upcoming server CPUs has been an ongoing thing, actually, some of which we have covered. Back in December, for example, a pair of next-gen EPYC 7003 series CPUs with 64-cores and 128-threads ripped through Cinebench 23, scoring an insane 87,878 in the multi-core test and 1,215 in the single-core...

AMD has not yet announced its next generation EPYC "Milan" server processors based on its Zen 3 CPU architecture, but they are coming, and presumably soon. Very soon, in fact, if the latest leak is any indication. For a period of time earlier today, a server listing on Dell's site in Canada highlighted a few different Milan options. The unannounced processors showed up within the configuration section for Dell's PowerEdge R6525 racker server system. It's a dual-socket 1U server system built for high performance computing (HPC), virtual desktop infrastructure (VDI), and virtualization workloads, and is currently available with EPYC "Rome" processors based on Zen 2. It looks as though at least... Read more...
AMD's Zen 3-based EPYC CPUs might be the worst-kept secret in all of technology. Details about these CPUs have been leaking onto the internet via Twitter since late last year. More recently, the 32-core EPYC 7543 made itself known via the Geekbench results database. AMD CEO Lisa Su all but confirmed rumors about 32-core CPUs at CES 2021, but stopped short of saying anything about bigger chips. Now, one of those bigger processors has leaked online thanks to Geekbench's online repository.  This result comes from an EPYC 7643 system running Geekbench 4 (which has a different score scaling than the current version 5) on Linux. This particular monster of a CPU will apparently have 48 cores as... Read more...
This should come as a surprise to absolutely no one who has been paying attention to the tech sector, but AMD is coming off a record quarter of earnings, which contributed to record fiscal year results. AMD capped off 2020 with $3.24 billion in revenue during the fourth quarter, up 16 percent sequentially and 53 percent year-over-year, and raked in $9.76 billion for the full year. That amounts to a staggering 45 percent jump in year-over-year revenue. After paying the bills, AMD was left with a $4.35 billion profit for all of 2020, up 52 percent from the previous year. The company has come a very long way from the days when it used to post quarterly and annual losses with alarming frequency.... Read more...
Zen 3-based Ryzen processors showed some really outstanding performance on the desktop when we looked at the Ryzen 9 5900X and 5950X. In the high-performance computing server space, though, 12 to 16 cores is the bare minimum, and systems only scale up from there. AMD has yet to announce its Zen 3 EPYC CPU platform, codenamed Milan, but configuration and performance scores are starting to leak online. The core count is purportedly huge and the performance looks to be through the roof.  Thanks to leaker ExecutableFix on Twitter, we've learned that the EPYC 7763 is a Zen 3 chip with 64 cores, giving it 128 hardware threads with symmetric multithreading, which is paired up with 256 MB of L3...

With so much attention being paid to graphics card leaks as of late, it could be easy to forget that new CPUs are on the horizon, too. That would be a shame, because Zen 3 is arguably just as interesting, considering the gains AMD has already made with its Zen architecture up to this point. While we continue to wait for Zen 3, a new leaks suggests AMD's upcoming architecture will give its EPYC server CPUs a sizeable boost in performance compared to its current-generation EPYC processors. We have heard quite a bit about Zen 3, most of which is unofficial information. Not all of it, however—AMD has made very clear (on multiple occasions) that Zen 3 will be arriving before the end of this... Read more...
AMD just reported its Q2 2020 earnings during a call this afternoon and the company delivered impressive results, spurred by solid sales growth. Specifically, AMD pulled in record revenue for Q2, which came in at $1.93 billion (a 23 percent year-over-year increase), while gross margins increased by 3 percentage points YoY to 44 percent.  Non-GAAP income came in at $216 million compared to $124 million during Q2 2019, while earnings per share were dialed-in at $0.18, compared to a street consensus of $0.16. This was an increase of $0.10 per share compared to the same quarter in 2019. How AMD achieved this growth is where it gets interesting, however. AMD attributed its stellar quarter to... Read more...
The big tech news this week is the official unveiling of Ampere, following months and months (years, really) of rumors. From the confines of his swank kitchen, NVIDIA CEO Jensen Huang dished up some details about the next-gen GPU, at least as it pertains to the data center high performance computing (HPC) markets. Following the announcement, AMD CEO Dr. Lisa Su revealed another interesting nugget—NVIDIA's DGX A100 servers are packing EPYC "Rome" processors inside rather than Intel Xeon chips. This is yet another feather for AMD's cap, which has been amassing them ever since Zen arrived (and in particular, the latest iteration, Zen 2). Proud to have @AMDServer #EPYC “Rome” CPUs...

AMD is the latest tech company to pledge millions of dollars in aid to support research institutions that are trying to better understand and develop a vaccine for COVID-19. Last week, Intel announced a $50 million initiative, and this week, AMD has announced its own $15 million donation to "accelerate medical research on COVID-19 and other diseases." In this case, that $15 million donation consists of some of the best enterprise computing hardware on the market: EPYC processors and Radeon Instinct GPU accelerators. EPYC processors are a well-known for their raw power and multi-threaded performance, with Zen 2-based configurations offering up to 64-core and 128-thread muscle. AMD... Read more...
AMD has been making some steady gains in desktop market share with its Ryzen 3000 processors, and has even showed some great promise with its newly released Ryzen 4000 mobile processors. But another segment that is incredibly crucial to AMD with respect to margins is the server market.  Intel has long been a dominant force in this sector, but AMD is two generations in with EPYC, and is in a stronger position than it has been in years. Zen 2-based EPYC 7002 processors have already been gaining attention from customers with configurations topping out with 64 cores/128 threads and today, AMD is introducing three new EPYC 7Fx2 Series processors that look to put...

Losing a bit of market share to Ryzen should have been a wake up call for Intel, and to some extent, it was—Intel said last September it was vowing to "aggressively compete in all segments." The troubled path to 10-nanometer production while rival AMD racks up wins with its 7nm tech should have been a wake up call as well. And lest another wake up call is still needed, Cloudflare is breaking up with Intel after a long relationship and courting AMD exclusively for its Gen X servers. Cloudflare is yet another feather in AMD's cap, and it speaks to the stiff competition Intel is facing against a rival that, quite frankly, struggled to compete in meaningful ways before Zen. But that was before,... Read more...
When it comes to its highly profitable Xeon Scalable server processors, Intel has been on the defensive as of late versus its chief rival AMD. While INTC has an overwhelmingly large lead in server processor market share, it also is looking to protect that lead with the release of its Cascade Lake Refresh processors. This is not a complete retooling of Intel's second-generation server processors, but rather some skillful optimization of features, speeds, feeds and pricing to make them more compelling for data center and enterprise customers. While Intel makes no comparisons to AMD’s EPYC 7002 processors in this release, the company does say that this new Cascade Lake Refresh offers up to... Read more...
