AMD Kaveri APUs offer a configurable TDP to target running the APU at lower power rating and this feature can be configured on supported motherboards. While the configurable TDP is targeted for the lower-end Kaveri APUs, I ran some tests from the A10-7850K when bumping its TDP from 95 Watts to 45 to 65 Watts to see how the performance is impacted.
To complement the many Intel vs. AMD CPU/APU Linux benchmarks published earlier this week as part of our AMD A10-7850K "Kaveri" APU coverage, here's some results mostly examining the performance-per-Watt and overall system power consumption of the many different Intel and AMD processors running Ubuntu Linux.
Two days ago AMD launched their "Kaveri" APUs to mixed reactions. On launch-day we provided a Linux overview of the AMD A10-7850K APU and followed that with an Ubuntu Linux vs. Windows 8.1 performance comparison for this top-end Kaveri APU. Yesterday was then the AMD Kaveri APU compared to discrete AMD/NVIDIA GPUs and now today we've finally had the time to finish the tests most people have been looking forward to: the A10-7850K comparison against various other AMD and Intel CPU/APUs. These Linux tests cover a range of both processor and graphics testing from Ubuntu 14.04 across a wide selection of Intel and AMD hardware.
Aside from sharing the Linux overview of AMD's A10-7850K "Kaveri" APU on Linux, for your viewing pleasure today I also have out some early OpenGL graphics benchmarks comparing the performance of the A10-7850K APU under Microsoft Windows 8.1 vs. Ubuntu Linux in its current 14.04 development form. These tests are a precursor to many more interesting AMD Kaveri benchmarks in the coming days.
This morning AMD is releasing the first APUs in their Kaveri family, their most advanced APU ever with up to 12 compute cores and is a big push forward with their overall HSA architecture. We managed to get our hands on a Kaveri system with A10-7850K APU and in the days/weeks ahead there will be many Linux benchmarks looking at the next-generation AMD APU. Here's what Linux users need to know right now about AMD Kaveri APU Linux support.
The Core i5 4670 is a mid-range Intel "Haswell" processor that's quad-core, clocked at 3.4GHz, and can top out at 3.8GHz all for a price of just over $200 USD. If you happen to be after a mid-range CPU with decent Linux open-source graphics support, check out our new comparative benchmarks of the Intel Core i5 4670 on Ubuntu Linux.
Earlier today on Phoronix I delivered benchmarks showing Intel's Haswell graphics falling behind Ivy Bridge on Linux, something not seen previously and certainly not what's expected. Curious to see whether this likely Intel Haswell Linux performance regression was limited to just the HD Graphics or the processor performance overall, here's the complementary set of Sandy Bridge, Ivy Bridge, and Haswell benchmarks. These tests span the Core i3/i5/i7 series when using the latest Ubuntu 14.04 packages and the Linux 3.13 kernel with these benchmarks focusing upon the processor performance.
The Intel Pentium G3220 is just a dual-core budget processor but the performance of this Haswell-based CPU has proven to be decent from the Lini PC, especially when it comes to the Intel HD Graphics on Ubuntu.
For those curious about the performance of Intel's Sandy Bridge and Ivy Bridge processors when upgrading to Ubuntu 13.10 and the experimental Linux 3.13 along with the latest stable GCC 4.8.2 compiler, here's some fresh benchmarks from several different Intel Core i3 and Core i5 CPUs.
Last week Amazon unveiled the new "C3" instance types for their Elastic Compute Cloud platform. The C3 instance types deliver their highest processor performance in Amazon's cloud. The C3 instances are backed by Intel Xeon E5 "Ivy Bridge" processors, use SSD-based storage, support AVX and Turbo as part of the Ivy Bridge feature set, and also deliver on improved network performance in the cloud. Coming out of Phoronix today for helping you measure cloud performance are benchmarks of all the new C3 instance types and compared to some bare metal systems running locally.
The ODROID-XU is the latest exciting ARM development board. Rather than aiming for low-cost like the Raspberry Pi, the ODROID-XU currently offers maximum performance when it comes to open ARM development boards. The ODROID-XU is based on ARM's big.LITTLE design and incorporates a quad-core Cortex-A15 for maximum performance or in its low-power state there's a quad-core Cortex-A7. The ODROID-XU also has with its Samsung Exynos 5 Octa also has a PowerVR SGX544MP3 GPU, 2GB of LPDDR3 memory, and USB 3.0 connectivity.
The Intel Core i3 4130 is a Haswell processor with HD Graphics 4400 and a dual-core part with Hyper Threading that retails for about $130 USD. While we have been amazed by the performance of high-end Core i7 Haswell CPUs, how's this budget-friendly processor? Here's a review of the Core i3 4130 CPU running Ubuntu Linux and compared to a variety of other processors.
At the beginning of September Intel launched the Intel Core i7 4960X processor as the long-awaited upgrade for their LGA-2011 platform. The Core i7 4960X is not Haswell-based but an Ivy Bridge Extreme Edition processor for maintaining socket compatibility and being derived from the Ivy Bridge Xeon. Over the Sandy Bridge Extreme processors, the Ivy Bridge upgrade brings 22nm processors to the socket and the top-end i7 4970X EE model is running at 3.6GHz with 4.0GHz Turbo, 15MB L3 cache, and has a 130 Watt TDP. There's been plenty of Windows benchmarks out there already for the Core i7 4960X EE while coming out today is our full Linux review with plenty of Ivy Bridge Extreme benchmarks on Ubuntu.
Earlier this month AMD unveiled their Richland desktop APUs as an upgraded version of Trinity. While still based upon Piledriver CPU cores, the AMD A10-6800K APU under Linux is a modest upgrade until the arrival of the Jaguar-based APUs. For starting off our Linux testing of the A10-6800K are Ubuntu Linux benchmarks of this high-end Richland APU compared against the A10-5800K Trinity APU.
Utilizing the core-avx2 CPU optimizations offered by the GCC 4.8 compiler can provide real benefits for the Intel Core i7 4770K processor and other new "Haswell" CPUs. For some computational workloads, the new Haswell instruction set extensions can offer tremendous speed-ups compared to what's offered by the previous-generation Ivy Bridge CPUs.
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.
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.
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.
For some additional benchmarks to share this weekend, here are some multi-core scaling numbers from the AMD FX-8350 Vishera that launched a few days ago.
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.
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 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.
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.
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.
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.
Here's some interesting test results recently uploaded to OpenBenchmarking.org that compares the performance of ARM Cortex A8 and Cortex A9 cores running at 1.0GHz against an Intel Atom N450. All three systems running at 1.0GHz were also running Gentoo Linux. Clock-for-clock, can the latest-generation ARM Cortex-A9 take out the Intel Atom? For the most part, yes.
It has been 66 days since Intel formally introduced their Ivy Bridge processors as the 2012 successor to Sandy Bridge. My views on Intel Ivy Bridge (specifically the Core i7 3770K model) back on launch-day were very positive in terms of the Linux compatibility, CPU performance, and the HD 4000 graphics capabilities. Since then I've conducted dozens of additional tests looking at the Core i7 Ivy Bridge on Linux in different areas from comparative benchmarks to Microsoft Windows, trying to run BSD operating systems on the latest hardware, looking at the virtualization performance, compiler tuning, etc. Here is a recap of this additional Ivy Bridge testing that has happened over the past two months of near constant benchmarking.
Last week I shared my plans to build a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The ARM cluster that is built around the PandaBoard ES development boards is now online and producing results... Quite surprising results actually for a low-power Cortex-A9 compute cluster. Results include performance-per-Watt comparisons to Intel Atom and Ivy Bridge processors along with AMD's Fusion APU.
The Linux OpenCL support for Intel CPUs is not in as good shape as the Intel Windows OpenCL support at this time, but here are some benchmarks that explore the Intel Ivy Bridge OpenCL performance under Linux.
Intel is finally announcing the first Ivy Bridge processors this morning. I have been extensively testing out the Intel Core i7 3770K, the current high-end Ivy Bridge processor, for the past few weeks under Ubuntu Linux. I have been extremely pleased with the Intel Core i7 Ivy Bridge processor under Linux with its phenomenal performance, power efficiency, and new features. This article is the first of many looking at the Linux performance of the new Intel Ivy Bridge processors.
