What we know about AMD’s Ryzen so far - barrerafordoon

Straight AMD fanboys take to admit that the company's CPUs harbour't been competitive with Intel's chips in a decade. With AMD finally unveiling its official CPU brand, Ryzen, this afternoon, as asymptomatic A the first chip's base clock speed, at that place are signs Intel might actually have a fight on its hands. Here's every single thing we know about AMD's Ryzen Mainframe so furthest.

The Specs

Present are all the spectacles we hump about AMD's coming Ryzen CPU next to its counterpart: the Broadwell-E Core i7-6900K.

Your conspiracy theory? Base

AMD dismayed the PC world in August by showing its 8-core Summit Ridge CPU (featuring Lucy in the sky with diamonds computer architecture) matching the performance of an 8-Congress of Racial Equality Intel chip in the open-beginning Blender application. The internet, of course, at once spawned cabal theories that AMD "probably" in use Blender because it could recompile the open-source program to run better on the Zen Buddhism architecture. Wrong.

PCWorld asked AMD officials if this was honest. We were told that entirely of the demos were done victimisation the compiled binary file from the Blender website.

Last week, AMD twofold down connected its performance claims by running not only the Blender test, but also additional demos of a Handbrake write in code and Pixologic's ZBrushCore benchmark. Wholly extremely multithreaded applications. And, yes, all performed using the positional representation system downloads sans any alterations, the troupe insists.

AMD demonstrated its new 8-core Ryzen CPU run a Handbrake write in code and slightly outpacing an Intel 8-core Core i7-6900K CPU.

Performance matches or exceeds Intel's 8-core CPU

In the fall Blender demo, AMD showed that Zen could go toe-to-toenail with its Intel vis-a-vis when clock speeds were exactly the same—3GHz in that case. That elevated the doubt of whether AMD could actually gather Intel's supreme velocity. The solvent is yes.

AMD says IT expects the Ryzen CPU to have a base clock of at least 3.4GHz, which is about 5 percent high than its Intel counterpart, the 8-core Broadwell-E 3.2GHz Core i7-6900K CPU. That same Intel chip, withal, will boost to 3.7GHz, and even hit 4GHz under single-threaded lashing.

AMD hasn't divulged Ryzen's boost hurry, so how serve we know it will be as fast, or possibly even faster, than Intel's Broadwell-E? For starters, in AMD's demos, Ryzen at 3.4GHz (with boosting turned turned) ran as as degraded as the Core i7-6900K in Blender, Handbrake, and ZBrushCore—and that was with the Core i7-6900K's boost mode on.

If we consider AMD's tests so far, and that Ryzen is the equal of Intel's Broadwell-E, then it comes down to time speeds that primarily separate these chips. Given AMD's statement that Ryzen will be at least 3.4GHz, it seems that its CPU will have a slight edge over Intel's.

Intel's 6th-gen, 5th-gen, 4th-gen, and 3rd-gen CPUs compared.

Ryzen vs. Skylake vs. Kaby Lake

Okay, so Ryzen looks good, but it's being matched against Intel's 5th-gen Broadwell core. What about Intel's 6th-gen Skylake and the soon-to-get in 7th-gen Kaby Lake desktop cow dung?

In fine efficiency, Skylake should throw a small vantage over Ryzen. Kaby Lake, which is for the most part a clock bump off from what we've seen in laptops, builds on it leading.

The problem, for Intel, is that the efficiency advantage isn't that substantial at equal clock speeds. American Samoa I noted in my review of Skylake, when I set 4 generations of Intel chips to the very time speed and disabled any boost advantage, the differences were pretty incremental (see above graph).

Of course, these parts don't all run at the similar speed. Skylake has a base clock speed of 4GHz. Kaby Lake, which is mostly a refined Skylake core, should receive a little more speed unruffled.

The first problem for Skylake (and probably Kaby Lake) is the power of the 8-core group chips to also flow at pretty high speeds on light oodles.

My limited review of the 10-core Broadwell-E shows how that nick's Turbo Max feature can largely nullify any clock-speed advantage the Core i7-6700K chip has in light loads. If AMD ass do the corresponding with its encourage modes, the base-time differences between Ryzen and Skylake could glucinium too minimal to matter.

The second problem with Skylake and Kaby Lake is that both are exclusive space-core parts with no more ability to add Sir Thomas More cores.

This isn't the last word connected carrying into action, but the superior general event—if you accept AMD's demonstrations at boldness value—is that Ryzen looks poised to place the troupe back into the ballpark for the first time in a long, prolonged time.

This AMD reference board for Ryzen from the uncover in the fall had four DIMM slots and that's because Ryzen is a dual-channel-memory CPU.

Information technology's dual-channel

One thing we haven't been sure about up until right away is whether Ryzen would be a quad-channel-memory CPU like its Intel counterpart. Today, I can say sure that it's a dual-television channel form.

That's because the demo we witnessed was prepared with a pair of 8GB DDR4 DIMMs, versus the Intel loge with four 8GB DDR4 DIMMs. AMD's recently announced Bristol Ridgeline chips are also dual-channel and use the same AM4 socket, and compatibility with Superman cores has been touted as a boast.

Aquaphobic that'll hobble Ryzen's performance? My own testing utmost class shows the impact to be mostly minimal.

The one negative to a dual-channel configuration is the limited amount of RAM you can pack into a organization (128GB on Intel versus 64GB with Ryzen). Intel might have a weak Mary Leontyne Pric advantage Here too since smaller DIMMs are usually cheaper.

AMD has the imaginable vantage of cheaper motherboard construction. Adding more memory channels to a motherboard way running more wires or traces and as wel more layers. Much layers means Thomas More monetary value.

You'll need a new AM4 motherboard and ice chest for Ryzen.

Motherboard, cooler, and power consumption

For many technical reasons, Ryzen just won't work in older AMD FX motherboards. A new mounting system means you'll need a newborn tank too, or at any rate an transcriber to make your existing ice chest fit.

Lengthwise Blender, AMD showed its new 8-core Ryzen CPU to use a little less power than the equivalent Intel CPU, which ran at about 100W.

AMD's nigh recent CPUs have got a reputation for running hotter than their Intel equivalents merely that doesn't look to be true any longer. The troupe showed Ryzen running ZBrushCore spell overwhelming slightly less power than the Intel Core i7-6900K running the same workload. AMD hasn't actually disclosed the quantity of heat, or TDP, the chip generates but did say people would follow "surprised."

UPDATE: AMD said during its Recently Horizon livestream that the 8-heart and soul Ryzen chip will have a 95W TDP, far little than the Core i7-6900K's 140W.

Yup, SLI will work on Ryzen motherboards. AMD showed a Ryzen and a Pith i7-6900K running Battlefield 1 with SLI'd GeForce Titan X cards.

Yes, SLI works

AMD knows that citizenry who buy 8-core CPUs incline to like cranking their systems to 11. In a nod to enthusiasts, the keep company demonstrated a Ryzen PC using a pair of Nvidia Titan X cards in SLI to run Battleground 1 against a similarly configured Core i7-6900K PC.

AMD same it wanted to prove that even with high-end configurations, Ryzen won't be a bottleneck.

The past good news program for enthusiasts is the assurance that we North Korean won't see some walled-soured AMD motherboard that forces you to run Radeon for multicard configurations. This International Relations and Security Network't without precedent. Near countertenor-end AMD motherboards support Nvidia SLI.

It's non really a CPU

AMD actually considers Ryzen to be an SoC, Oregon system on a chip, because each chip will consume few southeasterly bridgework functions such equally USB, PCI-E, and SATA. You can read more all but the reasons here, but the nitty-gritty is it was made to scale from laptops to servers so, delight, dude, proper nomenclature.
