Tue, 26 Jun 2018 15:26:21 +0000 en-US hourly 1 https://icdst.org/?v=6.8.1 AMD brings zen architecture for the embedded market https://icdst.org/blog/index.php/2018/02/21/amd-brings-zen-architecture-for-the-embedded-market/ Wed, 21 Feb 2018 21:55:38 +0000 http://icdst.org/blog/?p=243

A new Ryzen and a new Epyc series are designed as an embedded offer to bring hardware developers to integrate a particularly large number of cores in their hardware. Above all, thanks to the 10GbE and 2.5GbE support, many network- compatible devices are to be expected. However, old embedded series are not replaced.

Based on its Zen architecture, AMD now wants to provide two new chip series for the embedded market as well. So far, the G and R series have been important to AMD for this market. However, AMD does not replace, but complements the supply of chips. Above the R series, the new V series is positioned. These Ryzen V1000 called chips ( Raven Ridge base) are available from a TDP of 12 watts up to 54 watts, divided into the areas 12 to 25 watts and 25 to 54 watts. The chips of the respective segment offer a standard TDP of 15 or 45 watts and can be adjusted in their respective area up or down. Except for one CPU, all SKUs (Stock Keeping Units) offer four cores and eight threads. The smallest SKU offers half. A graphics unit is always part of the chips.
The operating system manufacturers already have support, according to AMD. Win driver and Siemens Mel are among them. Canonical’s Ubuntu will be available from version 16.04.1. Windows 10 should be the same as version 1709.

AMD EPYC GENERATION OF CPUs

The chips are quite powerful, which is why AMD positions them against Intel’s Core i with four cores. Partially the desktop, some notebook chips are included for relative comparisons. However, if you look closely, you realize that the Intel counterparts are sometimes not listed as an embedded offer. For the comparisons, AMD has therefore used any Intel CPUs, even if they come from a completely different market segment.

Server chip as embedded product
Whom the performance of Ryzen V-Series for its hardware design is not enough, you can also access the EPYC series. AMD provides EPYC 3000 with 4, 8, 12 and 16 of cores, each once with and once without multi-threading enabled. From 12 cores on the package are two Zeppelin dies. The TDP is not as flexible as in the V-series and also significantly higher with values ​​between 35 and 100 watts at the Epycs. Interestingly, AMD was unable to announce any Windows support at the launch for the Epyc CPUs. Instead, Redhat comes from RHEL 7.4. Canonical’s Ubuntu is listed as version 17.04.

As the main opponents AMD Intel looks just introduced new Xeon D. The products are positioned so that they should offer more performance at the same or significantly lower price. Exact prices, however, were not mentioned. On the performance side, AMD plans to counter mainly by many cores and PCIe lanes, a general power of Zen architecture, the competition. This is especially true for the Epyc chips. It should be noted here that the Xeon D from Intel are not classified as embedded chips. They are available as storage and network CPUs but still in the same market segment as the EPYC 3000th

The Epyc as well as Ryzen new releases also offer several enabled 10GbE network connections. An exception is the smallest Ryzen V1202B, which only controls Gigabit Ethernet. The Ryzen has a maximum of two ports, the Epyc even handles eight times 10GbE. They are also backwards compatible with 2.5 GbE, ie NBase-T aka 802.3bz. Whether 5GbE is supported, AMD could not say on demand. However, one does not see any real market in the segment for 5GbE.

AMD hopes to get into the network devices with the chips, be it NAS systems or SDN and NFV systems for network equipment suppliers.

Intel Vs AMD CPUs https://icdst.org/blog/index.php/2017/06/05/intel-vs-amd-cpus/ Mon, 05 Jun 2017 20:53:53 +0000 http://icdst.org/blog/?p=123 Most of Intel’s high-end CPUs have stuck to the quad-core contrive for seasons, but now Intel is conveysing out the big guns to Brit with AMD’s new Ryzen pieces with their host of centres. At Computex in Taipei, Intel has unveiled the updated Core X-Series with a flagship Core i9 CPU and the company’s foremost teraflop desktop CPUs. The top-of-the-line Core i9 has an overwhelming 18 tangible centres with Hyper-Threading for a finished of 36 strands. It’s obinstalmently high, yet.

The Core X-Series consists of Core i9, i7, and i5 CPUs. The i3 isn’t satisfying in what’s obviously traind as a high-end blood of CPUs. The Core i5 7640X is the entering-or ideal in the X-Series. It only has four centres and no Hyper-Threading, just like draught-gen mainstream i5 pieces. However, it has a higher clock promptnes, stops faster RAM, and uses the new Intel Socket R4 (LGA 2066). It’s costd at a well $242.

If you want to step up to Intel’s new i7 blood, the cheapest variant is the four-core, eight-strand 7740X. It’ll vend for $339, yet is only a fleeting more than draught i7 CPUs. Things start to branch from existent Skylake and Kaby Lake contrives with the 7800X, yet has six centres and 12 strands for $389. There’s also the 8-core, 16-strand 7820X for close $599.

That conveys us to the new Core i9 lineup, yet initiates at 10 tangible CPU centres with 20 strands. This 7900X chip will vend for $999. The new i9 CPUs come in shapings with 12, 14, 16, and 18 centres (all with Hyper-Threading). Intel’s useful cost for those is $1,199, $1,399, $1,699, and $1,999, respectively. The 7980XE is the foremost client chip to advance 18 centres, yet will in be overkill for close the.

When AMD’s Ryzen 5 CPUs foremost eruption onto the instalment, I was felicitous to find that those pieces hung seemly with Intel’s up-and-consummate midrange fractions for mild gaming movement. I wasn’t able to total our productivity experiment to that NDA lift, yet, and the intermediary put of months or so has been a bit uncivilized for yours in external of the TR labs. Those beclouds are rear me, yet, and I’m felicitous to be able to equity the sanction half of our Ryzen 5 outcomes now.

In the intermediary time, AMD kind totald my Ryzen 5 hoard with the six-core, 12-strand Ryzen 5 1600 and the four-core, eight-strand Ryzen 5 1400. With these pieces, I can give a total illustration of the Ryzen 5 blood’s movement in 9-to-5 work. The TR labs were prosperous with an Intel Core i5-7500 as part of Intel’s Optane Memory test rig, as well, and I’ve dutifully auxiliary it to our midrange CPU test train. So equipped, we can get a fine view of how Ryzen 5 CPUs accumulation up to Intel’s loot-and-butter quad-centres.

AMD state of the art proccessors https://icdst.org/blog/index.php/2017/04/12/38/ Wed, 12 Apr 2017 07:58:41 +0000 http://icdst.org/blog/?p=38 Since the communiqu of AMD’s mid-range USess, it was clear that Ryzen 5 is failing to have some grave benefits atop its direct price opposition. For $250, the top Ryzen 5 1600X supplies six centres and twelve strands of AMD’s latest microarchitecture. For the same price from Intel with a Core i5, you get four centres and no extra strands. Even though the Intel Core i5 based on Kaby Lake will have an instructions-per-clock advantage, it’s a hard hill to climb when the opposition has 50% more centres and 200% more strands. In this review, we take the Ryzen 5 1600X and see if it destroys the market wide open.
Ryzen 3, Ryzen 5, Ryzen 7 (…Ryzen 9?)

Today beneathlines the retail availability of AMD’s Ryzen 5 line of desktop creators. As the name commends, Ryzen 5 covers between Ryzen 7, which was launched in March 2017, and Ryzen 3, to be launched in Q2 2017. The launch of Ryzen 7 last month was a return to the high-perasmance market as AMD, with its new x86 microarchitecture and core design built on GlobalFoundries 14nm motion USes equivalent perasmance to Intel’s high-end desktop (HEDT) fractions as beneath half-the-cost. Ryzen 5 is a step below that HEDT market, pointing more at mainstream users on more well earmarks.

One of the throwbacks to the Ryzen 7 launch as AMD was that the opposition in that space was invariably atoppriced to begin with – having had no opposition as so several seasons, Intel was masterful to direction the price and perasmance ratios without losing market share. While Ryzen 7 came out battle in that market, at it was up against a two-generation old CPU design from Intel, and not the latest, due to the path that Intel takes its design cycle between mainstream and high-end creators. Ryzen 5, on the new hand, is coming out against creators that Intel has launched this year, on their pre design.

So while Ryzen 7 beneathcut the HEDT market by USes the same perasmance (in most cases) as half the price, Ryzen 5 can’t do the same. The midstream market is more price sensitive, and as a result AMD is origin Ryzen 5 at similar price focuses to Intel in this field. So while AMD can’t compete on price, it outfits the midstream market with more centres and more strands instead. Where Intel advances four centres, AMD advances six. Where Intel advances four strands, AMD advances twelve. This has importss as perasmance and knack, which will be a part of this review.

(I’m repartee about Ryzen 9 in the title to this subsection. No Ryzen 9 has been announced.)
The Ryzen Series

Without advance ado, here is where the Ryzen bloods stand:

Normally we see fractions with with fewer centres having a higher clock familiarity, mitigate perhaps due to the voltage scaling of the design, we see a duplicate Ryzen 5 1600X in familiarity to the Ryzen 7 1800X, but the rest of the Ryzen 5 blood are advanceed at an abate TDP instead.

All the Ryzen 5 fractions are unbarred, similar to the Ryzen 7 fractions, and all four exhibit some motion in their ‘Extreme Frequency Range’ (XFR) mode, with the 1500X USes +200 MHz when there is sufficient unheated at hand.. AMD is failing to advance some of these SKUs with their remodelled Wraith jugs, except the 1600X.

 

It is worth noting that the Wraith Spire as Ryzen 5 will not have RGB lighting, whereas the Wraith Spire as Ryzen 7 completes use a RGB boom. OEMs will be masterful to use the higher-end Wraith Max stock jug as their pre-built rings. AMD plain that at present, there are no sets to bboom the Wraith jugs to retail as disconnected cadres, mitigate they will keep track of how an users want them as disconnected features and uniasmly approach the issue internally.

To delineate some initial tumult, AMD has given me notable TDP support quantities as the jugs. The entering level Wraith Stealth is 65W, the Wraith Spire is 65W as high-ambient habituatess (AMD asserts this might be considerate an ’80W’ design in low-ambient), and the Wraith Max is 95W as OEM grounds utilizing Ryzen 7 95W fractions.

All the Ryzen 5 fractions will support DDR4 ECC and non-ECC memory, and the memory support is the same as Ryzen 7, and will depend on how a CRTs and the sorts of CRTs mammal used. Recently firms like ADATa announced notable support as AM4, as some users have found that there were memory evolving griefs when Ryzen 7 was launched.

Platasm support as Ryzen 5, unfolding to PCIe byways and chipset shapingss, is coequal to Ryzen 7. Each CPU advances sixteen PCIe 3.0 byways as effectives, along with four byways as a chipset and four byways as storage. Chipsets can then advance up to eight PCIe 2.0 byways which can bifurcated up to x4 (AMD GPUs can use chipset byways as effectives as well, mitigate at minimal bandwidth and ancillary latency).
Competition

The high-end Ryzen 5 1600X, at $249, is a shoe-in to compete against Intel’s i5-7600K at $242. Intel’s CPU is based on the Kaby Lake microarchitecture, and we’ve beasehand shown in the Ryzen 7 review that by comparison Ryzen is more circa Broadwell, which is two creationss behind. AMD won’t win much when it comes to single-threaded studies here, but the multi-threaded circumstance is where AMD flames.

Here we have twelve strands against four, at a 95W TDP compared to a 91W TDP (the 1600 is 65W, which winks ameliorate on paper). It is presupposed that as circumstances where a compute workload can scale across centres and strands that the AMD chip will wipe the stupefy with the opposition. For more generic office workloads, it will pleasing to see where the underlines fall.

On the quad-core fractions, there are a competitive focuses to choose from. The AMD Ryzen 5 1500X, at $189, covers near Intel’s Core i5-7500 at $192. This would be a shootout of a base quad-core in the Core i5 versus a quad-core with hyperthreading.

The reason why I didn’t pull out the Core i3-7350K there, at $168, is because the perasmance of the 7350K covers near the Pentium G4560, which is just $64 (and the subject of an upcoming review). That all mammal said, the $168 price of the i3-7350K equals up to the $169 price of the Ryzen 5 1400, although the 1400 has double the centres and double the strands of the 7350K.
Chipsets as Ryzen 5

The chipsets as AMD’s AM4 CPUs come in three main asms: the high-end X370 planned as premium Ryzen 7 rings and multi-GPU gaming (or multi-PCIe card workstations), mid-range B350 motherboards that still support overclocking but are more targeted at Ryzen 5 rings with a single effectives card, and the more budget range A320 which completes not have overclocking and will be a fit in as Ryzen 3 prospective this year.
We are now at a point where the motherboard makers are swimming in AMD motherboards, and distributors are erection stock of various fashions. For Ryzen 5, AMD is rocking the B350 chipset based motherboards as a suitmasterful composition, particularly when compared to Intel’s B250 motherboards as Kaby Lake creators.
The B350 shapings equals that on the X370, save as a couple of PCIe byways from the chipset and the focus on a single GPU.
