Ryzen 7 2700X CPUFreq Scaling Governor Benchmarks On Ubuntu Linux - Phoronix

Comparison of both AMD and Intel's flagship desktop processors, AMD Ryzen 7 2700X vs Intel Core i7-8700K.

Looks like AMD Ryzen 7 2700X is priced nicely to include the cpu cooler too.

For pricing, AMD has put the Ryzen 7 2700X below the i7-8700K, as well as bundling the Wraith Prism RGB stock cooler which easily replaces any $30-40 cooler, saving the user some money.

Phoronix benchmarks on Linux not bad

Redis needs optimising though on Linux

Ryzen 7 2700X CPUFreq Scaling Governor Benchmarks On Ubuntu Linux - Phoronix

Those launch-day Ryzen 5 2600X / Ryzen 7 2700X Ubuntu Linux benchmarks were using the "performance" governor, but some have alleged that the performance governor may now actually hurt AMD systems... Ondemand, of course, is the default CPUFreq governor on Ubuntu and most other Linux distributions. Some also have said the "schedutil" governor that makes use of the kernel's scheduler utilization data may do better on AMD. So I ran some extra benchmarks while changing between CPUFreq's ondemand (default), performance (normally the best for performance, and what was used in our CPU tests), schedutil (the newest option), and powersave (if you really just care about conserving power).

My main desktop is a Threadripper 1950x. Good to see AMD challenging Intel again.

Nice Threadripper 1950X is a beast ! As long as you're not using FreeBSD for Ryzen should be ok Ryzen Stability Issues Are Still Affecting Some FreeBSD Users - Phoronix

I love it. Vega 64 to go with it watercooled (not to derail thread lol)

Very nice rig there

Bios updates for better performance AMD Ryzen 7 2700X Linux Performance Boosted By Updated BIOS/AGESA - Phoronix

With last week's initial launch-day Linux benchmarks of the Ryzen 5 2600X / Ryzen 7 2700X some found the Linux performance to be lower than Windows. While the root cause is undetermined, a BIOS/AGESA update does appear to help the Linux performance significantly at least with the motherboard where I've been doing most of my tests with the Ryzen 7 2700X.

A Timely Discovery: Examining Our AMD 2nd Gen Ryzen Results

Due to the tight deadline of our testing and results, we pushed both our CPU and gaming tests live without as much formal analysis as we typically like to do. All the parts were competitive, however it quickly became clear that some of our results were not aligned with those from other media. Initially we were under the impression that this was as a result of the Spectre and Meltdown (or Smeltdown) updates, as we were one of the few media outlets to go back and perform retesting under the new standard.

Nonetheless, we decided to take an extensive internal audit of our testing to ensure that our results were accurate and completely reproducible. Or, failing that, understanding why our results differed. No stone was left un-turned: hardware, software, firmware, tweaks, and code. As a result of that process we believe we have found the reason for our testing being so different from the results of others, and interestingly it opened a sizable can of worms we were not expecting.

What our testing identified is that the source of the issue is actually down to timers. Windows uses timers for many things, such as synchronization or ensuring linearity, and there are sets of software relating to monitoring and overclocking that require the timer with the most granularity - specifically they often require the High Precision Event Timer (HPET). HPET is very important, especially when it comes to determining if 'one second' of PC time is the equivalent to 'one second' of real-world time - the way that Windows 8 and Windows 10 implements their timing strategy, compared to Windows 7, means that in rare circumstances the system time can be liable to clock shift over time. This is often highly dependent on how the motherboard manufacturer implements certain settings. HPET is a motherboard-level timer that, as the name implies, offers a very high level of timer precision beyond what other PC timers can provide, and can mitigate this issue. This timer has been shipping in PCs for over a decade, and under normal circumstances it should not be anything but a boon to Windows.

However, it sadly appears that reality diverges from theory – sometimes extensively so – and that our CPU benchmarks for the Ryzen 2000-series review were caught in the middle. Instead of being a benefit to testing, what our investigation found is that when HPET is forced as the sole system timer, it can sometimes a hindrance to system performance, particularly gaming performance. Worse, because HPET is implemented differently on different platforms, the actual impact of enabling it isn't even consistent across vendors. Meaning that the effects of using HPET can vary from system to system, as well as the implementation.

Ultimately, any benchmark software in play has to probe the OS to determine the current time during the benchmark to then at the end give an accurate result. However the concept of time, without an external verifying source, is an arbitrarily defined constant – without external synchronization, there is no guarantee that ‘one second’ on the system equals ‘one second’ in the real world. For the most part, all of us rely on the reporting from the OS and the hardware that this equality is true, and there are a lot of hardware/software engineers ensuring that this is the case.

Given that the difference between the two sets of data is related to the timer, one could postulate that the more granular the timer, the more the effect it can have: on both of our systems, the QPC timer is set for 3.61 MHz as a baseline, but the HPET frequencies are quite different. The AMD system has a HPET timer at 14.32 MHz (~4x), while the Intel system has a HPET timer at 24.00 MHz (~6.6x). It is clear that the higher granularity of the Intel timer is causing substantially more pipeline delays – moving from a tick-to-tick delay of 277 nanoseconds to 70 nanoseconds to 41.7 nanoseconds is crossing the boundary from being slower than a CPU-to-DRAM access to almost encroaching on a CPU-to-L3 cache access, which could be one of the reasons for the results we are seeing, along with the nature of how the HPET timer works.
