Intel Core i7 4770K "Haswell" Benchmarks On Ubuntu Linux

This past weekend I shared the first experiences of running Intel's new Haswell CPU on Linux. While Intel Haswell is a beast and brings many new features and innovations to the new Core CPUs succeeding Ivy Bridge, there were a few shortcomings with the initial Linux support. It still appears that the Core i7 4770K is still being finicky at times for both the processor and graphics, but in this article are the first benchmarks. Up today are benchmarks of the Intel Core i7 4770K when running Ubuntu 13.04 with the Linux 3.10 kernel.

The First Experience Of Intel Haswell On Linux

Haswell is here, Haswell is here, Haswell is here!!! After talking for months about the Linux kernel and driver development for Intel's Ivy Bridge successor, the heatsink can be lifted today on talking about Intel's Haswell processor. For the past few weeks I have been running and benchmarking an Intel Core i7 4770K "Haswell" processor on Linux to mixed success. While the Haswell improvements are terrific, the Linux experience now is awaiting improvements.

ARM Cortex-A15 vs. NVIDIA Tegra 3 vs. Intel x86

Last week I shared some early benchmarks of the Samsung Chromebook while running Ubuntu Linux. The Samsung Chromebook is very interesting since it's one of the few readily available computers on the market employing an ARM Cortex-A15 processor rather than Cortex-A9 or other models. The Cortex-A15 found in the Samsung Exynos 5 Dual SoC proved to be very powerful and this Chromebook was quite a good deal with it being trivial to load Ubuntu Linux (and other distributions) while costing only $250 USD for this ARM-based laptop. In the past week I have carried out additional ARM Cortex-A15 benchmarks, including a comparison of its performance the the NVIDIA Tegra 3 quad-core ARM "Cardhu" tablet and several Intel Atom/Core x86 systems.

AMD FX-8350 Linux Performance-Per-Watt

The latest Phoronix benchmarks to share of the AMD FX-8350 "Vishera" processor are performance-per-Watt results for the Piledriver eight-core processor compared to the previous-generation Bulldozer FX-8150. Tests were conducted when running at stock speeds as well as overclocked settings.

Calxeda ECX-1000 Benchmarks vs. Intel Atom, TI OMAP4

Last week I began delivering benchmarks of the low-power yet massively scalable Calxeda EnergyCore ECX-1000 ARM Server and followed the initial tests with some ARM compiler benchmarks and other benchmarks from this 5-Watt Linux Server. In this article is what many Phoronix readers have been waiting for: comparing Calxeda's quad-core Cortex-A9 ARMv7 performance against a dual-core Texas Instruments OMAP4460 PandaBoard ES and then an Intel Atom processor.

AMD FX-8350 "Vishera" Linux Benchmarks

AMD today is lifting the lid on their Piledriver-based 2012 FX "Vishera" processors. Just weeks after the "Bulldozer 2" Trinity APUs were launched, the new high-end AMD FX CPUs are being rolled out. Being benchmarked at Phoronix today under Linux is the new AMD FX-8350 processor.

AMD A10-5800K Performance On Ubuntu Linux

Continuing on from last week's initial benchmarks of the AMD A10-5800K Trinity APU on Linux, the Trinity memory performance testing, and then more benchmarks of the Radeon HD 7660D integrated graphics, here is the large Ubuntu Linux comparison of the AMD A10-5800K compared to the previous-generation AMD A8 Llano APU, an AMD FX-Series Bulldozer, and several Intel Core i3/i5/i7 CPUs from the Sandy Bridge and Ivy Bridge families.

AMD A10-5800K "Trinity" APU On Linux

While some information with Windows-based results for AMD's latest-generation "Trinity" desktop APUs have surfaced in the past few days, this morning the full embargo concerning the latest AMD Trinity hardware expires so full details and results can now be shared. In this article are the initial Linux test results of the AMD A10-5800K Trinity APU using Ubuntu at Phoronix.

Intel Core i5 3470

For the past month I have been testing out the Intel Core i5 3470 under Linux. Like Intel's other processors of recent years (well, ignoring the initial Sandy Bridge struggles), and just like the more expensive Ivy Bridge CPUs of this year, this mid-range quad-core processor is working very smoothly "out of the box" on modern Linux distributions.
