AMD Kaveri APUs feature a configurable TDP whereby users can opt to run their A-Series APUs with a lower power consumption and operating temperature but at the cost of slightly reduced performance.
At the end of July AMD launched new Kaveri APU models: the A10-7800, A8-7600, and A6-7400K. AMD graciously sent over review samples on their A10-7800 and A6-7400K Kaveri APUs, which we've been benchmarking and have some of the initial Linux performance results to share today.
Up for review today on Phoronix is the Pentium G3258, the new processor Intel put out in celebration of their Pentium brand turning 20 years old. This new Pentium G3258 processor costs under $100 USD and comes unlocked for offering quite a bit overclocking potential while this Pentium CPU can be used by current Intel 8 and 9 Series Chipsets. Here's our first benchmarks of the Intel Pentium G3258 using Ubuntu Linux.
Last week at Computex Intel formally announced the Core i7 4790K "Devil's Canyon" processor as a new, high-end, refreshed Haswell part. The Intel Core i7 4790K tops out at 4.4GHz and is quite interesting for PC enthusiasts and performance junkies. Today we're delivering the first public tests of the i7-4790K Devil's Canyon run under Linux.
This weekend when publishing preview benchmarks of NVIDIA's Tegra K1 from the Jetson TK1 development board, there were numerous requests by Phoronix readers to see this high-end ARM SoC pitted against the new AMD AM1 APUs. In this article are some benchmarks of Ubuntu 14.04 LTS on all of the AM1 Athlon and Sempron APUs compared to the Tegra K1 Cortex-A15 SoC.
Since receiving the NVIDIA Jetson TK1 ARM development board a few days ago that features the new Tegra K1 SoC I've been busy running a ton of benchmarks from this quad-core Cortex-A15 platform running Ubuntu Linux. Here's the first of some interesting numbers compared to other Intel x86 and ARM platforms.
Curious how AMD's new AM1 platform APUs compare to the original AMD Phenom processors? Wondering myself, I ran some tests showing how the Sempron 2650 and 3850 along with the Athlon 5150 and 5350 compare to the original Phenom 9500 and Phenom II X3 710 processors with RS780/RS880 motherboards. Besides the new APUs being competitive against the old hardware while costing much less than the original Phenom CPUs, their power consumption is also at a fraction of AMD's former high-end processors. Here's a brief but nice look at AMD's processing evolution in going from Phenom CPUs to today's AMD budget APUs.
With the initial Linux tests of the AMD Athlon 5150 / 5350 & Sempron 2650 / 3850 out of the way, I ran some basic overclocking tests on all four of these week-old AM1 APUs.
It's been a busy past few days since AMD launched their "AM1" Socketed Kabini APUs. After the initial Athlon 5350 Linux review on launch-day, I did some tests involving a faster kernel and newer Mesa code along with some reference DDR3 memory scaling benchmarks for these APUs with Jaguar processor cores. Since then the Athlon 5150 and Sempron 3850/2650 APUs arrived. After a busy weekend of benchmarking, here's the initial Ubuntu Linux benchmarks of all four AMD AM1 APUs that are available at this time: the Sempron 2650, Sempron 3850, Athlon 5150, and Athlon 5350. With these four new AMD APUs are also a number of thermal and power consumption tests.
Now that we've covered the general information about the new socketed Kabini APUs, here are our first benchmarks from the Athlon-branded Kabini APU we were seeded with by AMD: the Athlon 5350 with Radeon R3 Graphics. Let's see how this 25-Watt APU with four processor cores can perform under Ubuntu 14.04 Linux.
After much information being made public in March concerning AMD's AM1 platform that delivers socketed APUs for low-cost desktop systems, the first of these new socketed APUs are shipping today under the restored Athlon and Sempron branding. We've been fortunate enough to have one of the new Athlon AM1 APUs at Phoronix for a few days of testing.
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.
