The Ryzen Debut
The conundrum AMD currently faces started when information technology launched Bulldozer to lackluster reviews dorsum in 2011. The following years found it trying to right the send with Piledriver, Steamroller, and Excavator. Only it's safe to say the company'due south host processing portfolio never regained its lost luster. Meanwhile, Intel dominated the mobile, desktop, and server markets with a seemingly insurmountable performance built on the excellent Sandy Span design and an unrelenting cadence of incremental improvements.
Heading into today'southward review, nobody can argue the fact that AMD is far behind past comparison. Wouldn't that make a comeback all the more impressive, though?
We started seeing Zen micro-architecture teasers concluding year. Company representatives told us its next generation would usher in incredible functioning gains, matching or surpassing Intel's best efforts on multiple fronts. Zen also promised to revitalize an aging platform through Socket AM4 and new core logic. And AMD says it has a clear path forrad planned for time to come versions of Zen.
At some bespeak, though, the rubber has to run into the road. A good first pace was taking aim at a competitor. Intel's $thousand+ Core i7-6900K seemed like an ambitious choice, only early mitt-picked benchmark results made AMD's eight-cadre engineering samples await formidable. And then, announcing that the flagship model would sell for less than half of of the -6900K's cost sent the masses into a frenzy. Almost online vendors even sold out of their Ryzen 7 1800X allotment during pre-sales based on little more than AMD's ain endorsement.
At present it'due south time for Ryzen to stand on its own accord and show us what it tin do in the real-earth. We take several Ryzen SKUs in-business firm, spread across multiple Tom'due south Hardware labs. We've identified a number of unexpected results that bear continued investigation. Nosotros'll continue updating our coverage as answers materialize. But we want to start putting our findings in forepart of yous and then enthusiasts can make more informed buying decisions in the face up of general availability, which begins today.
Finding Zen
Four years ago, AMD began its work on the Zen core, which is its beginning clean-sail architecture since Bulldozer. AMD'southward initial objective was to transition from the 28nm procedure used for its modern APUs to GloablFoundries' 14nm FinFET node, which offers increased performance and density within a similar power envelope. The company too set an ambitious goal to increase didactics-per-clock throughput by 40% over Excavator through a series of design choices that significantly boost performance. Notably, AMD deployed a new architecture and a lithography shrink simultaneously, which is a daunting challenge.
Final year, we published Everything Zen: AMD Presents New Microarchitecture At HotChips. In that story, nosotros stepped through the composition of Zen, from front to back, right upwards to describing the CPU complex (CCX) responsible for housing four execution cores, each core'south 512KB L2 cache, and 8MB of shared L3 enshroud. If yous aren't already familiar with Zen and how it differentiates from prior-gen designs, bank check that piece out.
Moving forward, you demand to know that the Zen core is Ryzen'southward fundamental building block. All three SKUs we're introducing today employ two quad-core CCXes, adding upward to 4.eight billion transistors across the entire die. The company says its Infinity Fabric connects the CPU complexes, just remains shy nigh how that's a quantifiable benefit.
As we established in our architectural deep-swoop, AMD also artillery Zen with simultaneous multi-threading support, assuasive each physical core to operate on 2 threads in parallel. In theory, this improves the utilization of available hardware resource. A lot of our existent-world benchmarks bear that out with phenomenal performance gains. But other workloads betrayal teething pains we're still trying to diagnose.
How nearly the 40% IPC improvement goal AMD ready for itself? Well, afterwards factoring in the new micro-op cache (bypassing the L1 and L2 for frequently-accessed micro-ops), the improve branch prediction engine, the 1.75x-larger instruction scheduler window, and faster caches, the company cites a +52% last tally compared to Excavator. Naturally, we have our own single-threaded workloads to run and will gladly make comparisons using CPUs from our lab.
The Ryzen 7 Line-Upwards
AMD is splitting its newest CPUs into the eight-core Ryzen vii family, a 6-core Ryzen 5 serial, and the quad-core Ryzen 3 line-up. Only the Ryzen 7 SKUs are aircraft today, but it's easy to encounter that AMD is targeting Intel'south Core i7, i5, and i3 portfolios with a similar naming scheme.
Aside from Intel'southward viii- and ten-core i7s, the Ryzen 7s deliver higher core counts across the board. The AMD CPUs as well blow Intel's Broadwell-E prices out of the water, though iv-core/eight-thread Kaby Lake is generally cheaper (albeit with half as many cores).
It'due south not entirely clear what features AMD plans to roll out across the Ryzen 5 and three CPUs, simply nosotros practise know 7s sport the SenseMI suite. Nosotros'll go into more depth on SenseMI shortly. What's important here, though, is that SKUs with an X suffix include the eXtended Frequency Range adequacy. XFR automatically increases clock charge per unit beyond the mill-ready Precision Boost frequency if yous provide additional thermal headroom with an aggressive cooler. This extra bit of speed applies to two of the chip's cores.
AMD Ryzen 7 1800X
Ryzen vii 1700X
Ryzen 7 1700
Ryzen 7 is solely a host processor, devoid of integrated graphics. All 3 models debuting today drop into the Socket AM4 interface, include eight physical cores, and boast 16MB of shared L3 cache. They too sport unlocked ratio multipliers, though you'll need a motherboard based on the X370, B350, or X300 chipsets to overclock.
The Ryzen 7 1800X features a 3.six GHz base of operations frequency able to hit 4 GHz under lightly-threaded workloads via Precision Boost engineering. Both of those specifications are higher than Intel's viii-cadre Core i7-6900K. With Precision Heave enabled, all of the 1800X's cores can operate at iii.7 GHz. And with enough thermal headroom, ii cores spring as high as iv.1 GHz.
Perhaps surprisingly, given the comparisons to Intel's 140W Broadwell-E behemoths, 1800X bears a 95W TDP. If that's not enough to brand yous believe AMD has a new charter on life, the $500 cost tag should excite professional content creators especially. Of course, if you don't regularly find yourself running heavily-threaded tasks, Ryzen 7's value isn't equally pronounced. Later on all, Intel's Kaby Lake-based Core i5s and i7s offer solid performance and generally sell for less than the meridian-end AMD chips. Ryzen seven's operation in our benchmark suite will accept to justify the premium.
The 95W Ryzen vii 1700X's clock rates drib to 3.4 GHz base and iii.viii GHz under Precision Heave. Those frequencies compare favorably against the 140W Core i7-6800K, which tops out at 3.6 GHz in lightly-threaded tasks and only comes equipped with six cores. Worse, Intel charges $425 for the -6800K, while AMD is introducing Ryzen vii 1700X at $400. The Core i7-7700K also becomes relevant at this betoken, with its $350 cost tag.
AMD's Ryzen 7 1700 has a 65W TDP, making information technology the everyman-power viii-core desktop CPU available. A 3 GHz base of operations clock rate and three.7 Precision Boost ceiling are significantly lower than Intel's 91W Core i7-7700K. However, the company compensates with twice as many physical cores and a comparable price tag.
| Ryzen Retentivity Back up | MHz |
|---|---|
| Dual-Aqueduct/Dual-Rank/Four-DIMM | 1866 |
| Dual-Channel/Unmarried-Rank/Four-DIMM | 2133 |
| Dual-Channel/Dual-Rank/Ii-DIMM | 2400 |
| Dual-Aqueduct/Single-Rank/Ii-DIMM | 2677 |
The six-core/12-thread Ryzen 5 family unit should surface in Q2, and include at least ii models. The Ryzen 5 1600X will feature a 3.6 GHz base and iv GHz Precision Heave ceiling, while the 1500X is expected to get-go at 3.five GHz and ramp up to 3.vii GHz in lightly-threaded workloads. AMD hasn't shared cache configurations yet for those models. Ryzen 3s are also in the queue, though those aren't expected until the 2d half of 2017.
AMD geared its pricing structure to target the 99% of enthusiasts it says buy CPUs priced under $500. If Ryzen 7 is successful, the stage is prepare for even more disruption in the mid-range and low-stop segments too. So, does Ryzen begin its life on stronger ground than Bulldozer? Let's find out.
