AMD has just issued a new community update on its brand new Ryzen CPUs, addressing issues over thread scheduling on Ryzen processors - but also detailed the problems over temperature reporting on Ryzen.

AMD explains in the post that the "primary temperature reporting sensor of the AMD Ryzen processor is a sensor called 'T Control,' or tCTL for short. The tCTL sensor is derived from the junction (Tj) temperature-the interface point between the die and heatspreader-but it may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value. This approach ensures that all AMD Ryzen processors have a consistent fan policy".

The post continues in detail, with AMD explaining: "Specifically, the AMD Ryzen 7 1700X and 1800X carry a +20°C offset between the tCTL° (reported) temperature and the actual Tj° temperature. In the short term, users of the AMD Ryzen 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor. No arithmetic is required for the Ryzen 7 1700. Long term, we expect temperature monitoring software to better understand our tCTL offsets to report the junction temperature automatically".

Now that AMD has launched its Ryzen processors, some niggly issues have popped up with one of them being the underwhelming performance at 1080p. AMD has hit back with an official statement, saying: "the Windows 10 thread scheduler is operating properly for Zen".

AMD continues, saying that they "do not presently believe there is an issue with the scheduler adversely utilizing the logical and physical configurations of the architecture". There have been some differences between Windows 7 and Windows 10 performance over the thread scheduler, but AMD added that they "do not believe there is an issue with scheduling differences between the two versions of Windows" and that any performance differences between Windows 7 and Windows 10, come down to the difference between the operating systems - and not the Ryzen CPU.

AMD also talked about the SMT (the multi-threaded part of Ryzen) and the negative performance in some games, with the company saying that SMT offers a "neutral/positive benefit" in a range of processors. AMD added: "For the remaining outliers, AMD again sees multiple opportunities within the codebases of specific applications to improve how this software addresses the "Zen" architecture. We have already identified some simple changes that can improve a game's understanding of the "Zen" core/cache topology, and we intend to provide a status update to the community when they are ready".

Qualcomm recently announced their Snapdragon 835, the first 10nm SoC, and here we are already talking about 7nm chips.

Earlier this year, Samsung announced that they will start producing 7nm chips in early 2018, meaning they could be ready for their nex year's Galaxy S flagship.

According to a new report, MediaTek and TSMC are working together to bring a next-generation SoC. The 7nm SoC will have 12 cores.

AMD launched its Ryzen CPU family - at least the high-end 8C/16T parts in the Ryzen 7 range, but the server CPU market is about to be disrupted by their upcoming Naples CPU family.

Naples is a massively scalable 32C/64T system-on-chip (SoC) design, with support for two high-performance threads per core. We have 8-channel DDR4 support with room for 32 DIMMs on server boards, and so much more.

AMD Naples Features:

AMD has well and truly shaken up the CPU market with the release of Ryzen processors, led by the flagship Ryzen 7 1800X. Now that Ryzen is here, we're already hearing about Zen 2 - which will be known as Pinnacle Ridge.

The current Ryzen family of CPUs is known as Summit Ridge, but Zen 2 and Zen 3 should deliver better IPC performance, new features, and other goodies. Ryzen in its first-gen appearance had a 52% IPC (Instructions Per Clock) over the previous generation AMD CPU architecture - while Zen 2 and Zen 3 should deliver 5-15% improvements in IPC.

During a recent AMA on Reddit, AMD CEO Lisa Su said: "In new product development, you always learn a lot and we have our list of thingsthat we are adding to zen2 and zen3 to get even more performance going forward".

AMD has come out swinging in the desktop CPU market with their unbelievable Ryzen 7 family of CPUs, led by the impressive $499 chip in the Ryzen 7 1800X - but it's getting close to the time where they disrupt the datacenter market with Naples.

AMD's upcoming Naples CPU will offer up to 32 'Zen' cores, with huge bandwidth and IO numbers to boot, with "volume availability building in the second half of the year through OEM and channel partners". Forrest Norrod, senior vice president and general manager, Enterprise, Embedded and Semi-Custom business unit, AMD explains: "Today marks the first major milestone in AMD re-asserting its position as an innovator in the datacenter and returning choice to customers in high-performance server CPUs".

He continued: "Naples' represents a completely new approach to supporting the massive processing requirements of the modern datacenter. This groundbreaking system-on-chip delivers the unique high-performance features required to address highly virtualized environments, massive data sets and new, emerging workloads".

Intel is scrambling in what seems like a feverish emergency over AMD's new Ryzen processors, with Microcenter dropping Core CPU prices like crazy - and now, Intel is sending tech media emails saying "call us before you write" your Ryzen review. This is what happens when AMD launches their new Ryzen 7 1800X processor priced at $499, offering performance that rivals Intel's current $1000+ processor.

Charlie Demerjian, Semi Accurate founder and super-awesome comic book collector said: "Intel PR sent out a last-minute "call us before you write" email to most of the press, but not SemiAccurate, after hours last night. You could infer that they are suddenly really worried about something".

This isn't too far out of the norm for one company to email reviewers over their competitors' impending launch, but Intel seemed unstoppable... until Ryzen. Now, there are other reports that Intel will simply throw down more money than AMD can handle to fight Ryzen, and what I want to know now is - will Intel continue with its tease of AMD Radeon graphics inside of their CPUs? Now that Ryzen is a massive threat to their CPU monopoly, I think plans are going to change in a big way over the coming months.

AMD dropped its Ryzen processors onto the market a few days ago, hitting the #1 and #2 best-selling CPUs on Amazon within hours, breaking world records without breaking a sweat, and of course - hitting Intel where it hurts.

Intel has now reacted, as I thought they would - by reducing the prices of their Core range of processors across the board. Microcenter is already listing the processors with huge price reductions, with their flagship Core i7-6950X dropping by $300 ($1899 to $1599) while the Core i7-6900K drops by $200 from $1199 to $999, the Core i7-7700K has been slashed by $80 ($379 to $299). The full price cuts:

Now the question remains: how long until other retailers begin dropping the prices of their Intel CPUs - and will they get cheaper? Intel must be feeling the threat of Ryzen quicker than anticipated, for the company to be reacting this quickly - it only means great things for not just AMD, but the world.

AMD has launched its Ryzen CPU family to some huge fanfare, with the Ryzen 7 1800X and Ryzen 7 1700X becoming the #1 and #2 best-selling CPUs on Amazon within hours - and now, some retailers are already selling out of their first batches of pre-orders.

Right now, the Ryzen 7 1800X is unavailale on Amazon - with no ETA on new stock, with Newegg saying the Ryzen 7 1800X is out of stock. The Ryzen 7 1700X and 1700 processors are in stock for now, but I'm sure they're going to sell quickly - especially with news that the $329 processor can overclock to 4GHz+ and beat the Ryzen 7 1800X.

NCIX has the Ryzen 7 1800X, 1700X, and 1700 all available for pre-order (in both the US and Canada), while Memory Express has all 3 processors (for the Canadian market only). Fry's says that all of their Ryzen CPUs are now out of stock, so if you're in the market for a new Ryzen PC - you might want to pull the trigger, now.

AMD launched their higher-end/enthusiast Ryzen 7 range in the last 36 hours, with the flagship Ryzen 7 1800X - but it's the mainstream and mid-range CPUs that will be shifting the ground beneath Intel's feet - with the Ryzen 5 and Ryzen 3 range of chips.

Now we're hearing that AMD will be launching their Ryzen 5 and Ryzen 3 range of CPUs in Q2 2017 - which means sometime between April and June, perfect for a huge unveil during Computex in late-May, early-June. Ryzen 5 will aim at the Core i5 processors from Intel, with 6C/12T - providing more CPU threads than the higher-end Core i7-7700K and its 4C/8T.

The Ryzen 5 1600X is meant to cost $259, while the Ryzen 5 1500 will cost $229. Ryzen 3 will arrive as 4-core CPUs, and they should be CHEAP AS CHIPS, offering some great performance and more CPU threads for the CPU intensive games/applications out there.
