Last week in Sonoma, AMD denounced new sum on a arriving CPU architecture, codenamed Zen. For a past 16 years, AMD has relied on a multiple of Greek (Athlon, Phenom) and Latin-derived (Duron, Opteron). More recently, it’s used a aged “FX” moniker from a high-end Athlon 64 consumer hardware to marketplace Bulldozer and Piledriver-derived CPUs. Going forward, Zen will be marketed underneath a “Ryzen” code name (pronounced RYE-zen).
AMD didn’t only betray a branding — it gave some additional sum on a CPU’s smallest time frequency, sum L2/L3 cache, and new capabilities as well.
When AMD tested Zen opposite a Core i7-6900K behind in August, it sealed both chips to 3GHz. This lifted concerns that AMD competence run during a significantly reduce time than Intel does, serve harming a company’s ability to contest effectively. We now know that’s not going to occur — AMD isn’t divulgence accurate SKUs yet, or even a comprehensive smallest bottom clock, yet a association has reliable that it will offer an eight-core chip with during least a 3.4GHz bottom clock. The 20MB of cache doesn’t mention between L2 and L3, yet that’s easy to mangle down — we’ve already been told that any CPU formidable (CCX) consists of 4 CPU cores corroborated by 8MB of L3 cache. Two CPU complexes = 8 cores and 16MB of common L3, with 512KB of L2 for any CPU core. Each L3 cache appears to be singular to a core complex; it’s not transparent what a chastisement strike is for retrieving information stored in a opposite CCX’s L3.
There’s a new height refurbish entrance as well, with support for PCIe 3.0 and USB 3.1 Gen 2. AMD has been constrictive with Asmedia for a southbridge designs and we design that will continue. AMD continues to insist that Zen represents a 40% alleviation in IPC over Excavator, yet it still hasn’t common sum on how it arrives during that calculation, or either that includes a opening boost from a new symmetric multithreading record SMT.
The following slideshow stairs by some of a new facilities AMD announced in Sonoma and their impact on opening and energy consumption. AMD is collectively referring to these technologies as SenseMI, where a MI refers to “Machine Intelligence.” It’s a crafty bit of branding meant to gain on a new recognition of AI and low training research. All slides can be clicked to open and increase them in a new window.
AMD is still being decorous about launch dates, yet Lisa Su has publicly settled that we’ll see Zen in Q1 2017. we design a association to reason that date, yet if AMD was rising Ryzen during CES it substantially would’ve already pronounced so. Since there’s always a few weeks of post-CES decompression, this puts a Zen launch somewhere between late Jan and late March. The 3.4GHz core time for an eight-core chip is also good to see — it compares good opposite Intel’s altogether product lineup, and it gives AMD’s possess eight-cores an critical boost opposite prior Piledriver chips. That competence not seem important, given how feeble regarded Piledriver is, yet it’s a feeble regarded chip with a bottom time of 4.7GHz during a tip finish of AMD’s product stack. That’s 38% aloft than Ryzen’s now-specified 3.4GHz smallest bottom clock, and 56% aloft than a 3GHz time AMD was display in August. We always approaching Ryzen would kick Piledriver, yet it was never transparent by how most once clockspeed differences were accounted for. A 3.4GHz bottom time should give AMD some-more respirating room.
The following slideshow is from one of a prior deep-dives on Zen, yet will give we some-more sum on a design if you’re personification catch-up. Our altogether opinion on a chip’s expected rival positioning and a thoughts on positioning vs. Intel are accessible here.
It’s no deceit to contend a whole destiny of AMD hangs on this launch. AMD’s primary businesses have effectively collapsed, and a company’s CPU and graphics income is 27% of what it was in Q3 2011. Zen represents an event to energise a companies server and consumer fortunes. Historically, these markets were distant some-more critical to AMD’s bottom line than GPU sales, even yet we’re also anticipating that Vega has what it takes to offer Nvidia some foe in a mainstream GPU and even HPC markets. Enthusiasts have been watchful a prolonged time for an AMD CPU that could contest with Intel’s Core i3 / i5 / i7 families — hopefully in a few months some-more they’ll have one.
