AMD A10-7850K Kaveri: The Linux Introduction

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.

Intel Core i5 4670 On Linux

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.

Intel Core i3/i5/i7 Ubuntu Linux Performance Update

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.

Benchmarking Amazon's New EC2 "C3" Instance Types

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.

ODROID-XU's ARM big.LITTLE A7 + A15 Octa-Core

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.

Intel Core i3 4130 On Linux

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.

Intel Core i7 4960X Ivy Bridge Extreme Edition

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.

AMD A10-6800K Richland APU On Linux

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.
