Intel’s Architecture Day was held yesterday and brought announcements of three new technologies. Intel shared details of a new 3D stacking technology for logic chips, a brand new CPU architecture for desktop and server, and some surprising developments on the iGPU front. Oh, and they mentioned that whole discrete GPU thing…
3D Stacking for Logic Chips
First we have Foveros, a new 3D packaging technology that follows Intel’s previous EMIB (Embedded Multi-die Interconnect Bridge) 2D packaging technology and enables die-stacking of high-performance logic chips for the first time.
“Foveros paves the way for devices and systems combining high-performance, high-density and low-power silicon process technologies. Foveros is expected to extend die stacking beyond traditional passive interposers and stacked memory to high-performance logic, such as CPU, graphics and AI processors for the first time.”
Foveros will allow for a new “chiplet” paradigm, as “I/O, SRAM, and power delivery circuits can be fabricated in a base die and high-performance logic chiplets are stacked on top”. This new approach would permit design elements to be “mixed and matched”, and allow new device form-factors to be realized as products can be broken up into these smaller chiplets.
The first range of products using this technology are expected to launch in the second half of 2019, beginning with a product that Intel states “will combine a high-performance 10nm compute-stacked chiplet with a low-power 22FFL base die,” which Intel says “will enable the combination of world-class performance and power efficiency in a small form factor”.
Intel Sunny Cove Processors - Coming Late 2019
Next up is the announcement of a brand new CPU architecture with Sunny Cove, which will be the basis of Intel’s next generation Core and Xeon processors in 2019. No mention of 10nm was made, so it is unclear if Intel’s planned transition from 14nm is happening with this launch (the last Xeon roadmap showed a 10 nm transition with "Ice Lake" in 2020).
Intel states that Sonny Cove is “designed to increase performance per clock and power efficiency for general purpose computing tasks” with new features included “to accelerate special purpose computing tasks like AI and cryptography”.
Intel provided this list of Sunny Cove’s features:
- Enhanced microarchitecture to execute more operations in parallel.
- New algorithms to reduce latency.
- Increased size of key buffers and caches to optimize data-centric workloads.
- Architectural extensions for specific use cases and algorithms. For example, new performance-boosting instructions for cryptography, such as vector AES and SHA-NI, and other critical use cases like compression and decompression.
Integrated Graphics with 2x Performance

Intel did reveal next-gen graphics, though it was a new generation of the company’s integrated graphics announced at the event. The update is nonetheless significant, with the upcoming Gen11 integrated GPU “expected to double the computing performance-per-clock compared to Intel Gen9 graphics” thanks to a huge increase in Execution Units, from 24 EUs with Gen9 to 64 EUs with Gen11. This will provide “>1 TFLOPS performance capability”, according to Intel, who states that the new Gen11 graphics are also expected to feature advanced media encode/decode, supporting “4K video streams and 8K content creation in constrained power envelopes”.
And finally, though hardly a footnote, the new Gen11 graphics will feature Intel Adaptive Sync technology, which was a rumored feature of upcoming discrete GPU products from Intel.
And now for that little part about discrete graphics: At the event Intel simply “reaffirmed its plan to introduce a discrete graphics processor by 2020”. Nothing new here, and this obviously means that we won’t be seeing a new discrete GPU from Intel in 2019 - though the beefed-up Gen11 graphics should provide a much needed boost to Intel’s graphics offering when Sonny Cove launches “late next year”.

The 40th anniversary of the original Intel 8086 microprocessor launch is just days away (June 8), and ahead of this VideoCardz.com has posted screen captures of online listings for the rumored 8086 anniversary CPU - the Core i7-8086K.
(Screen captures above sourced from VideoCardz.com)
"Some retailers have already started listing the new SKU on their websites, indicating 70 USD/EUR premium over i7-8700K (~480/470 EUR). Not much is known at this point, but the CPU is rumored to be 5.0 GHz chip out of the box. It is, however, still expected to be a 6-core SKU."
Beyond the online retailer listings accidentally posted early, presumably, not much is known; though it seems fair to conclude that this may indeed be a higher-clocked version of the current i7-8700K and would therefore remain a 6-core/12-thread product. Intel is going to be at Computex beginning June 5 where they "will showcase how the company is powering the future of computing" so might we hear an announcement of a new product on the eve of the 8086 anniversary? The possibility is too logical to ignore.

The news will apparently get worse before it gets any better for Intel, as the company updated their security recommendations for the Spectre/Meltdown patches for affected CPUs to address post-patch system restart issues. Specifically, Intel notes that issues may be introduced in some configurations with the current patches, though the company does not recommend discontinued use of such updates:
" Intel recommends that these partners, at their discretion, continue development and release of updates with existing microcode to provide protection against these exploits, understanding that the current versions may introduce issues such as reboot in some configurations".
Image credit: HotHardware
The recommendation section of the security bulletin, updated yesterday (January 17, 2018), is reproduced below:
- Intel has made significant progress in our investigation into the customer reboot sightings that we confirmed publicly last week
- Intel has reproduced these issues internally and has developed a test method that allows us to do so in a predictable manner
- Initial sightings were reported on Broadwell and Haswell based platforms in some configurations. During due diligence we determined that similar behavior occurs on other products including Ivy Bridge, Sandy Bridge, Skylake, and Kaby Lake based platforms in some configurations
- We are working toward root cause
- While our root cause analysis continues, we will start making beta microcode updates available to OEMs, Cloud service providers, system manufacturers and Software vendors next week for internal evaluation purposes
- In all cases, the existing and any new beta microcode updates continue to provide protection against the exploit (CVE-2017-5715) also known as “Spectre Variant 2”
- Variants 1 (Spectre) and Variant 3 (Meltdown) continue to be mitigated through system software changes from operating system and virtual machine vendors
- As we gather feedback from our customers we will continue to provide updates that improve upon performance and usability
Intel recommendations to OEMs, Cloud service providers, system manufacturers and software vendors
- Intel recommends that these partners maintain availability of existing microcode updates already released to end users. Intel does not recommend pulling back any updates already made available to end users
- NEW - Intel recommends that these partners, at their discretion, continue development and release of updates with existing microcode to provide protection against these exploits, understanding that the current versions may introduce issues such as reboot in some configurations
- NEW - We further recommend that OEMs, Cloud service providers, system manufacturers and software vendors begin evaluation of Intel beta microcode update releases in anticipation of definitive root cause and subsequent production releases suitable for end users
Intel recommendations to end users
- Following good security practices that protect against malware in general will also help protect against possible exploitation until updates can be applied
- For PCs and Data Center infrastructure, Intel recommends that patches be applied as soon as they are available from your system manufacturer, and software vendors
- For data center infrastructure, Intel additionally recommends that IT administrators evaluate potential impacts from the reboot issue and make decisions based on the security profile of the infrastructure
Intel has worked with operating system vendors, equipment manufacturers, and other ecosystem partners to develop software updates that can help protect systems from these methods. End users and systems administrators should check with their operating system vendors and apply any available updates as soon as practical.

AMD announced today a price drop for most of its Ryzen processor lineup, making the company's multi-core-focused parts even more competitive to Intel in terms of cost-to-performance. While not every Ryzen and Threadripper processor is seeing a price reduction, many parts are being reduced by up to 30 percent.
|Processor||Cores/Threads||Previous SEP||New SEP||Percent Reduction|
|Ryzen 7 1800X||8/16||$499||$349||-30.1%|
|Ryzen 7 1700X||8/16||$399||$309||-22.5%|
|Ryzen 7 1700||8/16||$329||$299||-9.1%|
|Ryzen 5 1600X||6/12||$249||$219||-12.0%|
|Ryzen 5 1600||6/12||$219||$189||-13.7%|
|Ryzen 5 1500X||4/8||$189||$174||-7.9%|
|Ryzen 5 2400G||4/8||$169||N/A|
|Ryzen 3 1300X||4/4||$129||$129||N/A|
|Ryzen 3 2200G||4/4||$99||N/A|
Note also in the price chart the new "G" series Ryzen APUs with integrated Radeon Vega graphics. Check pcper.com for more info on this new part.
Some of the new prices are already reflected, and in some cases reduced further, at retailers like Amazon.
To determine the new prices, AMD performed comparative price testing with its online retail partners last quarter, and determined that these new prices were the best balance between performance and value.
With second generation Ryzen processors not scheduled to launch until later this spring, the price drop not only helps AMD move existing inventory, it also keeps the company at the top of enthusiasts' minds in the midst of the fallout around the recent processor security issues, one of which primarily affects Intel processors.

Intel has officially announced their new workstation processor lineup, with Xeon Scalable and Xeon W versions aimed at both professional and mainstream workstation systems.
"Workstations powered by Intel Xeon processors meet the most stringent demands for professionals seeking to increase productivity and rapidly bring data to life. Intel today disclosed that the world-record performance of the Intel Xeon Scalable processors is now available for next-generation expert workstations to enable photorealistic design, modeling, artificial intelligence (AI) analytics, and virtual-reality (VR) content creation."
The first part of Intel’s product launch announcement are the new Xeon Scalable processors, first announced in July, and these are dual-socket solutions targeting professional workstations. Versions with up to 56 cores/112 threads are available, and frequencies of up to 4.20 GHz are possible via Turbo Boost. Intel is emphasising the large performance impact of upgrading to these new Xeon processors with a comparison to older equipment (a trend in the industry of late), which is relevant when considering the professional market where upgrades are far slower than the enthusiast desktop segment:
“Expert workstations will experience up to a 2.71x boost in performance compared to a 4-year-old system and up to 1.65x higher performance compared to the previous generation.”
The second part of announcement are new Xeon W processors, which will be part of Intel’s mainstream workstation offering. These are single-socket processors, with up to 18 cores/36 threads and Turbo Boost frequencies up to 4.50 GHz. The performance impact with these new Xeon W CPUs compared to previous generations is not as great as the Xeon Scalable processors above, as Intel offers the same comparison to older hardware with the Xeon W:
“Mainstream workstations will experience up to a 1.87x boost in performance compared to a 4-year-old system4 and up to 1.38x higher performance compared to the previous generation.”

Intel launched the first half of its X-Series processor lineup earlier this year, releasing up to the 10-core i9-7900X. But with the upcoming release of AMD's 16-core Threadripper 1950X, the real interest among enthusiasts are the specs of Intel's high core count X-Series parts.
After previously teasing partial specs for these parts, Intel today finally unveiled the complete details, starting out with the i9-7920X (12 cores/24 threads) with a 2.9GHz base and up to 4.4GHz boost clock and topping out with the i9-7980XE (18 cores/36 threads) with a 2.6GHz base and 4.4GHz max boost clock. Check the table below for the complete specifications:
|i9-7980XE||i9-7960X||i9-7940X||i9-7920X||i9-7900X||i7-7820X||i7-7800X||TR 1950X||TR 1920X||TR 1900X|
|Base Clock||2.6 GHz||2.8 GHz||3.1 GHz||2.9 GHz||3.3 GHz||3.6 GHz||3.5 GHz||3.4 GHz||3.5 GHz||3.8 GHz|
|Turbo Boost 2.0||4.2 GHz||4.2 GHz||4.3 GHz||4.3 GHz||4.3 GHz||4.3 GHz||4.0 GHz||4.0 GHz||4.0 GHz||4.0 GHz|
|Turbo Boost Max 3.0||4.4 GHz||4.4 GHz||4.4 GHz||4.4 GHz||4.5 GHz||4.5 GHz||N/A||N/A||N/A||N/A|
|DDR4-2666 Quad Channel||DDR4-2666 Quad Channel|
|TDP||165 watts||165 watts||165 watts||140 watts||140 watts||140 watts||140 watts||180 watts||180 watts||180 watts?|
From a pure core-count perspective, the Threadripper 1950X goes up against Intel's i9-7960X, but with a $700 difference in price. With Intel CPUs holding and IPC advantage over AMD, however, it's likely that the i9-7920X, and perhaps even the 7900X, will best Threadripper in certain gaming and productivity workloads.
Also interesting in Intel's announcement today are the base clocks of the 12-core i9-7920X (2.9GHz) and the 14-core i9-7940X (3.1GHz). Intel pushed the TDP of the 7940X to 165W, allowing it to increase the base clock over its 12-core counterpart. This suggests that Intel expects the 14-core 7940X, at a price-point of $1399, to be a popular choice in terms of price-to-performance.
Finally, Intel's release today reveals that all of the upcoming X-Series parts will have 44 PCIe lanes, compared to the 64 lanes AMD is offering on all Threadripper parts. There was some debate in the office this morning about how Intel's 44 lanes should cover most configurations for the foreseeable future, but this still remains one clear advantage for AMD's platform.
Intel's 4- to 10-core processors are already on the market. Intel says that the 12-core 7920X will launch August 28th, while the 14- to 18-core parts will launch about a month later, on September 25th.

You may have heard that Intel's upcoming 8th-generation processors, code named Coffee Lake, won't be compatible with the current Z270 chipset motherboards. Last week we had another round of rumors and reports about these upcoming - and totally incompatible - new CPUs, with wccftech reporting some details on what to expect with the new processors. Spoiler: MORE CORES.
Image credit: Tech Advisor
We begin with the Intel Core i7-8700K, which will reportedly be the company's first mainstream 6-core processor, with previous hex-core offerings limited to HEDT and server. The i7-8700K will run slightly below the current 4-core i7-7700K, with a base frequency of 3.7 GHz (vs. 4.2 GHz with the i7-7700K) and single-core Turbo speeds topping out at 4.3 GHz according to the report. Another point of interest with the 6-core i7 part is TDP, with 95W needed where even the current HEDT parts are into the 130W territory. What of the Core i5? This is where things get a little more interesting, as there appear to be 6-core parts in the i5 family as well, without Hyper-Threading of course. Even the Core i3 parts jump to 4-core configurations with Coffee Lake, which would obviously be another first.

To editoralize a bit, AMD seems to be in a highly influential position in the wake of Ryzen and Threadripper, as Intel is (reportedly, of course) upping the core counts for Core series processors. Sure, Intel could have done this anyway, but looking at their pre-Ryzen products they were quite happy selling 2 - 4 core parts for premium prices before. This is great news for anyone in an era of increasingly multi-thread optimized computing (as long as pricing remains at or below current offerings), and with this healthy competition the second half of the year might be the best time in a very long time to upgrade - be it Intel or AMD. Now, if only graphics cards would fall back down to earth...

Update 07/11/17: We have now heard from Intel on this subject, and they provided this statement regarding the availability of the Pentium G4560 processor:
"We continue to offer the Intel Pentium SKU referenced. What you have observed on websites are possibly part of a normal demand fluctuation."
(The original post follows.)

Sound far-fetched? It seems at least plausible that Intel might consider some sort of CPU-related moves to maintain profit margins with Ryzen providing some very real competition after several years of Intel dominance. The popularity of the 2-core/4-thread Pentium G4560 - a (theoretically) ~$60 Kaby Lake part that provides a very nearly Core i3-level experience (some features are missing) is not at all surprising, and the current lack of availability and subsequently higher pricing (lowest in-stock price at around $80 at time of publication) suggests that something is up with this CPU.
Chart via PCPartPicker
A low of $78.89 for the CPU with an MSRP of $64 is about a $15 markup, but this price is just going to increase if no fresh stock hits the market as these sell out.
Now some editorial: Why would Intel introduce what is essentially a slightly hobbled Core i3 into the market at half the cost of their cheapest Core i3 to begin with? I enthusiastically endorsed this seemingly questionable business decision (along with all of the buyers of this often out-of-stock CPU) when it first hit the market a few months ago, and now - if rumors are to be believed - the company might just be killing it off. This would be a move reminiscent of Nintendo's recent NES Classic, which was apparently too popular for its $59.99 price tag (and scalpers worldwide rejoiced). Nintendo, of course, killed the NES Classic when it was at its height of popularity, perhaps as it was just not profitable enough to justify continued production? (And besides, a soon-to-be-$300-on-eBay SNES Classic was in the works.)
Might the Pentium G4560 be Intel's NES Classic? It seems a little too likely for comfort.

Tagged: xeon, Skylake, processor, pentium, microcode, kaby lake, Intel, errata, cpu, Core, 7th generation, 6th generation
A microcode bug affecting Intel Skylake and Kaby Lake processors with Hyper-Threading has been discovered by Debian developers (who describe it as "broken hyper-threading"), a month after this issue was detailed by Intel in errata updates back in May. The bug can cause the system to behave 'unpredictably' in certain situations.
"Under complex micro-architectural conditions, short loops of less than 64 instructions that use AH, BH, CH or DH registers as well as their corresponding wider register (eg RAX, EAX or AX for AH) may cause unpredictable system behaviour. This can only happen when both logical processors on the same physical processor are active."
Until motherboard vendors begin to address the bug with BIOS updates the only way to prevent the possibility of this microcode error is to disable HyperThreading. From the report at The Register (source):
"The Debian advisory says affected users need to disable hyper-threading 'immediately' in their BIOS or UEFI settings, because the processors can 'dangerously misbehave when hyper-threading is enabled.' Symptoms can include 'application and system misbehaviour, data corruption, and data loss'."
The affected models are 6th and 7th-gen Intel processors with HyperThreading, which include Core CPUs as well as some Pentiums, and Xeon v5 and v6 processors.
