Testing Out The Configurable TDP On AMD's Kaveri

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.

Intel vs. AMD Performance-Per-Watt On Ubuntu 14.04 Linux

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.

AMD A10-7850K vs. Intel/AMD CPU/APU Comparison

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.

AMD A10-7850K Kaveri: Windows 8.1 vs. Ubuntu Linux

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.

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.

Intel Pentium G3220 Haswell

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.

Intel Core i3/i5 Linux Performance Update

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.

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.
