  Cannonlake Discussion Thread
Posted by: SteelCrysis - 02-11-2017, 12:19 AM - Forum: General Hardware - No Replies


Quote:During its annual investors day, Intel shed some light on upcoming Cannonlake architecture. The company promises over 15 percent better performance compared to Kabylake. While no exact numbers were shared, it was told that they are based on SysMark benchmark.

More importantly, Intel Cannonlake is currently expected to ship in the second half of 2017. This probably means entry-level parts with faster CPUs coming at a later date.

It’s also worth noting that the slide below is clearly comparing i7 series, a direct competitor to AMD Ryzen, which is expected to launch later this month.

  7nm Intel CPUs Are Coming In 3–4 Years
Posted by: SteelCrysis - 02-09-2017, 03:51 AM - Forum: General Hardware - No Replies


Quote:Now, Intel has announced that it will be bringing Fab 42 online, but not as a 14nm facility. Instead, Fab 42 will be brought online at the 7nm node, and to be online within 3-4 years. Intel expects to create approximately 3,000 jobs directly, with a 10,000-job impact on Arizona itself. Semiconductor manufacturing work in Arizona pays a median wage of $22 per hour (~$46,000 per year) according to the BLS. That’s not fabulous, but a family with two full-time earners at that pay rate would be well above the median household income in the United States.
One possibility is that Intel decided to build Fab 42 out so it would have a near-new fab to deploy Extreme Ultraviolet Lithography, or EUV. The company has previously stated that it doesn’t anticipate introducing EUV before the 5nm node, which would put it roughly six years away from now. If the now-cancelled 450mm wafer initiative could’ve sparked new capital expenditures, the EUV rollout (if it ever happens) could be even harder to retrofit into existing facilities. At present, EUV equipment requires vastly more power and cooling to operate compared to 193nm ArF, and some pieces of equipment are considerably larger.

To be clear, this is speculation on my part — but I strongly suspect that Fab 42 will be completed with an eye towards fitting it out for easier EUV adoption in the future. Intel has not forecast that it expects the PC market to improve in the near future, but the company could be betting that increased datacenter demand and cloud service scaling will drive future product adoption, even if the consumer market declines further.

  Devastating Bug Is Killing Intel Atom C2000 CPUs
Posted by: SteelCrysis - 02-09-2017, 03:46 AM - Forum: General Hardware - No Replies

Ordinarily, Atom CPUs are of no interest to us, but this story about them is:

Quote:Intel hardware is, generally speaking, extremely reliable. Every processor and chipset has some degree of bugs, but these issues rarely become critical flaws that jeopardize a product. Evidence is mounting, however, that Intel’s C2000 server platform — that’s the Avoton and Rangeley low-power server variants, all of which are based on Atom — have a serious flaw that’s bricking hardware.

Cisco has released an advisory warning informing its customers of the following: “In some units, we have seen the clock signal component degrade over time. Although the Cisco products with this component are currently performing normally, we expect product failures to increase over the years, beginning after the unit has been in operation for approximately 18 months. Once the component has failed, the system will stop functioning, will not boot, and is not recoverable. This component is also used by other companies.”

So how does this link back to Intel, given that Cisco declined to name a vendor? Sharp-eyed boffins at The Register spotted an errata notice Intel issued in January, 2017. Intel’s AVR54 reads:

Problem: The SoC LPC_CLKOUT0 and/or LPC_CLKOUT1 signals (Low Pin Count bus clock outputs) may stop functioning.

Implication: If the LPC clock(s) stop functioning the system will no longer be able to boot.

Workaround: A platform level change has been identified and may be implemented as a workaround for this erratum”

The problem appears to affect all current steppings of the C2000 product family. While a platform fix has been identified, many manufacturers are choosing to recall products altogether rather than apply it. Cisco has announced that it will proactively replace hardware that was still under warranty or any other type of valid service contract as of November 2016. Hardware will be replaced whether it has already failed or not. Cisco isn’t formally using the word “recall,” but that’s what this is.

Did Intel use NDAs to squash reporting?

ServeTheHome did some digging into the situation and found multiple vendors willing to acknowledge being affected by the issue: Cisco, Netgate, QCT, and Supermicro all acknowledged the flaw — but not the cause.

ServeTheHome states that it has spoken to eight separate vendors, none of whom were willing to acknowledge which supplier was responsible. Multiple vendors cited NDAs with their suppliers that prevented them from identifying the source. Not many companies have the clout to force multi-billion dollar corporations to kowtow to its desire for secrecy. Not many suppliers are in a position to dictate to their customers how they will and won’t address a problem or speak to its cause. And of course, there’s the fact that Intel just updated its own documentation to identify exactly the problem in the C2000 family that eight separate vendors (so far) have acknowledged in their own products.

If you have Avoton or Rangeley hardware deployed for any reason, including as a component in embedded systems or networking hardware, we recommend contacting the vendor to determine whether replacement hardware is required or available.

  Pentium G4560
Posted by: SteelCrysis - 02-09-2017, 01:18 AM - Forum: General Hardware - No Replies

It has to be asked: is this the end of i3s as we know them?

Quote:The G4560 at $64 is pretty amazing. It not only invalidates the Core i3 range but it also kills off the higher end Pentiums as well. It's 22% cheaper than the $82 G4600 and yet it's clocked just 3% lower. Similarly, it's 31% cheaper than the G4620 while it can't possibly be more than 5% slower.

Intel's Core i3 range doesn't look any better. For instance, the i3-7100 retails for $117 and besides a bump in operating frequency and a slight change in iGPU, this is the exact same processor as the G4560. Clocked at 3.9GHz, the i3-7100 is up to 11% faster, but that doesn't make it worth 80% more.

Comparisons only get worse as you go on: the Core i3-7300 costs well over twice the price but comes clocked less than 15% greater. Realistically, your choices are the G4560 at $64 or the Core i5-7400 at $190, everything else in-between is a bit pointless.

Against older chips such as the Skylake Core i3-6100, the Pentium G4560 wasn't a great deal slower in our Excel and Photoshop workloads and the same was true when looking at encoding performance.

The chip is no slouch in gaming either, proving to be the perfect companion for a graphics card akin to the RX 460, GTX 1050 or 1050 Ti (it worked also well with the GTX 1060 though we think a sub-$200 GPU makes more sense for playing CPU-intensive games on the G4560).

With two cores and no Hyper-Threading, Intel's previous entry-level Pentium G4400 struggles in today's games. By adding Hyper-Threading to its Kaby Lake Pentiums, Intel has given this series a new lease on life, albeit while cannibalizing sales of its Core i3 range.

Really interesting. If this is true, what does the future hold for mainstream i7s? And reportedly these new Kaby Lake CPUs will start sampling by the end of this week.

  Quadro GP100 With 16 GB HBM2
Posted by: SteelCrysis - 02-06-2017, 10:53 AM - Forum: Video - No Replies

Wow. Nvidia is already able to use HBM2. AMD won't have an edge on them in VRAM tech. And Tom's will be testing this beast.

Exclamation Nvidia Prevents Geforce Experience Game Codes From Being Shared
Posted by: SteelCrysis - 02-03-2017, 01:00 AM - Forum: General Hardware - No Replies

Ugh. Now if I don't care about a game I got with my Nvidia graphics card, I can't give the game code to a friend.

Quote:Simply put, it’s now virtually impossible to resell or gift a game code attained from a GPU or PC offer due to the new hardware authentication process. Requiring a GeForce Experience login in addition to providing the GPU’s serial number and point of sale permanently assigns that coupon to the purchaser’s account, and you can’t redeem multiple copies for regifting, as Steam and other online game platforms allow.

  Tinfoilhat Sweeny Flushes His Credibility Down The Toilet Again
Posted by: SteelCrysis - 02-01-2017, 06:12 AM - Forum: Gaming - Replies (3)


Quote:Tim Sweeney is at it again, this time calling out Microsoft on Twitter for its rumored upcoming Windows 10 Cloud SKU. The new OS will be similar to Windows RT, in that it will run UWP that are installed from the Store. Of course, these are still early reports, as it's not entirely clear that Microsoft won't allow users to sideload apps as well.
No, it's not OK. Microsoft is a monopoly with a large majority of PC OS market share, and is barred from forced "tying" by antitrust law.
Of course, Valve is exempt from this since they are still bundling Steam with SteamOS, but the FTC doesn't care about Valve or is in Valve's pocket, as proven by the fact that they still won't go after Valve for Steam Early Access prohibiting competition on price and blatantly violating the Sherman Antitrust Act.
