Intel X299 Platform and Core i7-7740K CPU Leaked in Sisoft Database

Early last month, rumors stirred that Intel was planning on releasing two new CPUs to combat AMD’s recently launched Ryzen CPUs. Following the initial rumors, information about the rumored CPUs have been quiet however, new information regarding the mysterious Intel Core i7-7740K processor and the X299 platform have surfaced thanks to some recently uploaded benchmarks in the SiSoft benchmark database.

The information leaked from the SiSoft database confirms that the Intel Core i7-7740K is indeed a 4C/8T CPU. Operating frequency is currently set at 4.3GHz (base) and 4.5Ghz (boost). The CPU also comes with 1MB of L2 and 8MB of L3 Cache. For comparison, the [...]

New Linux Kernel Fixes SMT Issue for AMD Ryzen CPUs

For those having issues with their new AMD Ryzen CPU’s SMT functionality in Linux, the latest kernel version 4.10.3 rectifies the issue which was present in kernel version 4.9 and below.

Older versions of the Linux kernel bundles both the threadID and the APIC ID together when SMT is enabled. This causes the OS to assign a unique CPU Core ID to each thread instead of the same CPU ID to a pair of threads.

The Linux kernel development page describes the error as the following:

our SMT scheduling topology for Fam17h systems is broken, because the ThreadId is included in the ApicId when SMT is enabled. So, without further decoding cpu_core_id is unique [...]

AMD Issues Update on Ryzen Addressing Thread Scheduling, Temperature Reporting, Power Plans, and SMT

In a recent blog post, AMD’s Robert Hallock recently posted an update on some of the big issues currently surrounding the new Ryzen processor including thread scheduling, temperature reporting, power plans, and SMT.

 

Thread Scheduling

Previously some media outlets reported that there may be an issue with the Windows 10 thread scheduler and Ryzen, but it appears that the thread scheduler is actually working properly in Windows 10. This has been verified Sysinternals Coreinfo v3.31 topology logs and the only reason an issue was believed to have existed is because an older version of Sysinternals Coreinfo was used.

AMD Ryzen CPUs In-Stock, But Where’s the AM4 Motherboards?

Last week, AMD launched their highly anticipated Ryzen CPUs to huge fanfare and for the most part, the CPU has lived up to its expectations. While there is still quite a bit of controversy over whether or not it’s a strong CPU for gamers, other applications that are highly multi-threaded such as video editing or 3D modeling show Ryzen to be very clearly competitive against its Intel counterparts.

Overclockers Rejoice! AMD Ryzen CPU Confirmed Using Solder TIM with IHS

Ever since Intel’s Ivy Bridge CPUs launched back in 2012, Intel has consistently caught flak for using cheap TIM (Thermal Interface Material) to interface the CPU die with the IHS (Integrated Heat Sink). This unfortunately created a necessity for those looking for even decent overclocks to have to remove the IHS, or de-lid the CPU.

With AMD’s Ryzen CPU launching soon, many have wondered what type of TIM (Thermal Interface Material) AMD is using with their upcoming processors. In a recent video posted to YouTube, German overclocker der8auer not only demonstrates how to de-lid an AMD Ryzen 7 1700 CPU, but also provides us with the good news that AMD is using [...]

While pre-order rankings and information has been limited from other vendors, similar numbers may have also been seen across the industry as a recent article by Digitimes reports that AMD’s initial shipment of Ryzen CPUs are expected to top one million units. Motherboard makers are also expected to cash in on AMD [...]
