Athlon II X3 vs. Ryzen 3: How AMD's Performance Has Evolved & Performance-Per-Watt

Noticing I had an AMD Athlon II X3 425 system still racked up and hadn't been powered on in a long time, I decided to decomission it, but not before running some final benchmarks on that system. Having the recent AMD Ryzen 3 1200 / 1300X CPUs I decided it would make for an interesting comparison how the old Athlon II X3 compares to AMD's low-end CPU of today, the Ryzen 3 processors based on Zen. Here are those benchmarks that also include performance-per-Watt and overall AC system power consumption numbers.

Intel Core i7 7820X Linux Benchmarks

While the June launch of Intel's X-Series processors took the attention with the top-end Core i9 7900X Skylake-X and Core i7 7740X Kabylake-X processors, coming in several hundred dollars less than the i9-7900X is the i7-7820X, which still packs a very hard punch. We have now received a Core i7 7820X for Linux testing at Phoronix and are beginning with a round of benchmarks on Ubuntu.

Continuing To Stress Ryzen

In direct continuation of yesterday's article about easily causing segmentation faults on AMD Zen CPUs, I have carried out another battery of tests for 24 hours and have more information to report today on the ability to trivially cause segmentation faults and in some cases system lock-ups with Ryzen CPUs.

AMD Ryzen 3 1200 & Ryzen 3 1300X Linux Performance

At the end of July AMD began shipping the Ryzen 3 entry-level Zen processors. While it may not be as exciting as a 16-thread Ryzen 7 or Threadripper, the Ryzen 3 1200 and Ryzen 3 1300X offer surprising value with being quad-core parts priced at just above $100 USD. With Linux users especially craving multi-core systems if running Arch or other distributions where you are frequently compiling your own packages, the Ryzen 3 CPUs can make for a low-cost but practical Linux system. Here are my initial benchmarks of these first two Ryzen 3 processors.

Intel Core i9 7900X Linux Benchmarks

Since the Intel Core-X Series were announced last month at Computex, I've been excited to see how well this high-end processor will perform under Linux... Linux enthusiasts have plenty of highly-threaded workloads such as compiling the Linux kernel, among other packages, and thus have been very excited by the potential of the Core i9 7900X with its ten cores plus Hyper Threading and sporting a 13.75MB cache. With finally having an X299 motherboard ready, here are my initial Ubuntu Linux benchmarks for the i9-7900X.

Running The Ryzen 7 1700 At 4.0GHz On Linux

Many Phoronix readers appear rather intrigued by the AMD Ryzen 7 1700 on Linux as it offers good multi-threaded performance with eight cores / 16 threads and retails for just $329 USD. Making the Ryzen 7 1700 even more appealing to enthusiasts is that it overclocks well. For those curious, here are benchmarks of the Ryzen 7 1700 on Ubuntu Linux running at 4.0GHz.

AMD Ryzen 7 1700 Linux Benchmarks: Great Multi-Core Performance For $329

Yesterday we posted launch-day Ryzen 7 1800X Linux benchmarks that were particularly appealing for multi-core / heavily-threaded workloads like code compilation. Given all the code compilation done by Linux users in particular, if you were intrigued by the Ryzen 7 1800X performance but find the $499 USD price-tag to be too higher, today I have my initial benchmark figures on the Ryzen 7 1700. The Ryzen 7 1700 is still eight cores and sixteen threads but will only set you back $329 USD as the current low-end Ryzen processor for what's currently available.

Fresh RadeonSI Mesa Git Gaming Benchmarks On 7 Linux Desktops

When posting last week our Windows 10 vs. Ubuntu Radeon benchmarks and Windows vs. Linux NVIDIA Pascal benchmarks and then the Windows vs. Linux relative performance analysis, as usual, it didn't take long for some to argue that the Linux gaming performance is actually faster but "Unity 7 is slower" and the similar FUD that is usually waged whenever looking at cross-platform performance.

Intel Celeron G3930 On Linux: A Dual-Core Kabylake CPU For $40

Earlier this week we posted Linux benchmarks of the Intel Pentium G4600 as a 3.6GHz processor for around $90 USD. It was an interesting processor for the value, but if your wallet is tighter, the Celeron G3930 is selling for about $40 as a dual-core sub-3GHz Kabylake processor. Here are those test results.

Kaby Lake On Linux Plays Much Better With CPUFreq Than P-State

After ordering a Core i5 7600K Kaby Lake CPU last week, I've been spending the past few days trying it out under Ubuntu Linux. If you happened to pick up an early Kaby Lake CPU and seeing low performance, I wanted to pass along a little PSA while I am still working on additional tests.

Intel Core i7 6800K Benchmarks On Ubuntu + Linux 4.8

While the Core i7 6800K has been available for a few months now, there hadn't been any review on it since Intel hadn't sent out any Broadwell-E samples for Linux testing this time around. However, I did end up finally buying a Core i7 6800K now that the Turbo Boost Max 3.0 support is finally coming together (at first, Intel PR said it wouldn't even be supported on Linux) so that I can run some benchmarks there plus some other interesting items on the horizon for benchmarking. Here are some benchmarks of the i7-6800K from Ubuntu 16.04 LTS with the Linux 4.8 kernel.
