AMD Integrates Ryzen Power Patch in Latest v17.10 Chipset Drivers

AMD is continuing to deliver on their promise to improve Ryzen’s performance. The newest chipset drivers (v17.10) now integrate AMD’s Ryzen Balanced Power Plan.

The new power plan will reduce the latency for the CPU to transition between p-states (power states) for those who want to use a balanced power plan. Previously, when using the Windows balanced power profile, the transition can take up to 30ms depending on the situation and the only fix available was to set Windows to utilize the high-performance power profile. The reason for this is because Windows did not properly support Ryzen’s power management features and by setting the power profile to [...]

Intel Rumored to Launch Basin Falls X299 Platform, LGA2066 CPUs at Computex

With AMD’s Ryzen CPUs launched several months ago, there’s currently some major competition in the high end desktop CPU space which Chinese tech publication Benchlife claims may have prompted Intel to push forward the launch of their next generation HEDT platform, codenamed Basin Falls, to the May/June Computex timeframe. This is well ahead of its original Q3 or Q4 launch schedule.

According to the article, Intel is poised to show off its X299 Basin Falls platform at Computex along with its upcoming Skylake-X and Kaby Lake-X CPUs.

Based on a new Socket R4 (LGA 2066), the new X299 platform is a major update to the X99 platform bringing support [...]

AMD Releases Ryzen Balanced Power Plan to Improve Performance, Reduce Power Consumption in Ryzen CPUs

Although AMD’s Ryzen CPUs launched to a rocky start, AMD has shown that they’re fiercely working on improving the platform, releasing three community updates within just a few weeks of the initial Ryzen 7 launch.

One of the issues that had been plaguing early Ryzen adopters is that the Windows 10 default “Balanced” power profile isn’t optimized to properly utilize Ryzen’s power saving capabilities which resulted in reduced performance with the Balanced power profile engaged. The reason for this is because with the Windows Balanced Power Plan, Windows sets higher thresholds and longer timers for transitions across P-states, and [...]

Ryzen 5 1400 Gaming Performance Leaked Before Launch

AMD’s Ryzen 5 CPUs aren’t expected to launch until April 11 so up until now, benchmarks for the Ryzen 5 series were simulated by disabling cores on the octa-core Ryzen 7 series CPUs. However, according to a recent video released by Youtube channel Santiago Santiago, we get a glimpse at Ryzen 5 1400 performance in the flesh thanks to a retailer which appears to have jumped the gun on sales of the upcoming CPU.

In the video, the CPU was benchmarked with eight games: Battlefield 1 (DX12), Fallout 4, GTA 5, Hitman (DX12), Just Cause 3, Assassin’s Creed: Unity, The Witcher 3, and Rise of the Tomb Raider (DX 12). The test bench consists of an HIS Radeon RX [...]

Nvidia Driver May Cause Inconsistent Benchmark Results in Rise of the Tomb Raider

Youtube channel AdoredTV recently uncovered a potential shortcoming in Nvidia’s drivers which can cause performance dips when a Nvidia graphics card is paired with a Ryzen CPU.

When paired with a Nvidia graphics card, AMD’s Ryzen 1800X falls short – sometimes by as much as 40% – when compared to an Intel Core i7-7700K running Rise of the Tomb Raider. GPU statistics collected during benchmark runs reveal that the Ryzen-based system wasn’t pushing the GPU to 100%, causing it to lag behind the Intel-based system. This was consistent in both DX 11 and DX 12 benchmarks. Normally, this would indicate a bottleneck on the CPU, which was strange [...]

AMD Ryzen Optimization Patch Released for Ashes of Singularity, Claims 30% Performance Improvement

As with any major new CPU architecture, AMD’s Ryzen CPU is experiencing some growing pains early out the gate as gaming performance had been a little less impressive than expected. This can be seen in games such as Ashes of the Singularity where although both multi-thread and single-core performance were competitive against Intel’s 6-core Core i7-6800K and even the 10-core Core i7-6900K in many other benchmarks, it trailed behind Intel’s Quad-Core Core i7-7700K in several gaming benchmarks.

As a result, many were baffled at the performance results. If the Ryzen 7 1800X could adequately compete against Intel’s top-end Core i7-6900K in both single and [...]

AMD Ryzen 16-Core CPU, 12-Core CPU in the Works: Features Using Multiple Dies on MCM

Recently, the rumormill has been spinning after it was revealed that AMD may be introducing an even higher end desktop CPU with 12 and 16-cores based on AMD’s new Zen based architecture. A recent article posted by Turkish technology site, DonanimHaber, provided some new details regarding the upcoming processors.

According to the article, AMD will be releasing a 16-core, 32-thread and a 12-core, 24-thread Zen based CPU by combining multiple AMD Ryzen “Summit Ridge” CPUs in what’s called a MCM, or Multi-Chip Module. In the 16-core, 32-thread CPU, two full Ryzen 8-core dies are combined while the 12-core, 24-thread CPU will combine two Ryzen 6-core [...]

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 [...]
