The Kaveri Refresh 'Godavari' Review: Testing AMD's A10-7870K
by Ian Cutress on June 1, 2015 11:59 AM ESTProfessional Performance: Linux
Built around several freely available benchmarks for Linux, Linux-Bench is a project spearheaded by Patrick at ServeTheHome to streamline about a dozen of these tests in a single neat package run via a set of three commands using an Ubuntu 11.04 LiveCD. These tests include fluid dynamics used by NASA, ray-tracing, OpenSSL, molecular modeling, and a scalable data structure server for web deployments. We run Linux-Bench and have chosen to report a select few of the tests that rely on CPU and DRAM speed.
C-Ray: link
C-Ray is a simple ray-tracing program that focuses almost exclusively on processor performance rather than DRAM access. The test in Linux-Bench renders a heavy complex scene offering a large scalable scenario.
NAMD, Scalable Molecular Dynamics: link
Developed by the Theoretical and Computational Biophysics Group at the University of Illinois at Urbana-Champaign, NAMD is a set of parallel molecular dynamics codes for extreme parallelization up to and beyond 200,000 cores. The reference paper detailing NAMD has over 4000 citations, and our testing runs a small simulation where the calculation steps per unit time is the output vector.
NPB, Fluid Dynamics: link
Aside from LINPACK, there are many other ways to benchmark supercomputers in terms of how effective they are for various types of mathematical processes. The NAS Parallel Benchmarks (NPB) are a set of small programs originally designed for NASA to test their supercomputers in terms of fluid dynamics simulations, useful for airflow reactions and design.
Redis: link
Many of the online applications rely on key-value caches and data structure servers to operate. Redis is an open-source, scalable web technology with a strong developer base, but also relies heavily on memory bandwidth as well as CPU performance.

@Ian CutressYou last tested AMD A6-A10 using both Starswarm and #dMark API Overhead test.
When you pulished those results it was determined that all AMD APU's A6-A10 outperform Inteel i3, i5 and i7 by 100% in drawcalls and frames per second.
What was the 3dMark API Overhead for A10-7870K?
How did it perform using Starswarm?
You have those benchmarks why didn't you present them here?
When I spend money I would like to know how the silicon will perform on using high performance software.
Ignoring the impact of DX12 is absurd,
Any new systems with AMD A10-7870K will be Windows 10 and the gaming will be either with Mantle or DX12.
Users will tolerate DX11 only until the legacy games get ported to a better API.

What games do you suggest he test with DX12? Oh wait, there arent any. The few games tested with mantle showed minimal gains with an APU in real gaming preformance, not some artificial benchmark.ToTTenTranz - Monday, June 1, 2015 - link
DX12 performance may be predicted by testing a Mantle title.0VERL0RD - Monday, June 1, 2015 - link

I hope they can actually bring Carrizo to the FM2+ platform.Cryio - Monday, June 1, 2015 - link

Back in the day the idea of a 95 watt part didn't even make me blink twice. 'Like having a light-bulb on", I thought. Now - in the age of LED light-bulbs it makes me wince. The thought of it feels like leaving a faucet on with all the electricity running out, draining the well.LOL. Whatever the reason and how ever logical I simply wouldn't buy a 95 watt part today for general use. What is the point with so many parts pulling a fraction of that and perfectly able to handle day-to-day chores?

If you really care about energy:-You and your family will use a towel not a hair dryer
-You and your family will use bycicle, public transportation or simply walk (check nederlands)
-Implies no car.

Do you have a point? I don't own a hair dryer and I use public transport. It's not exactly hard or uncommon.Lolimaster - Monday, June 1, 2015 - link
TDP does not mean power consumption, and the actual measures are with the cpu @full load both gpu/cpu. You don't run a cpu/apu full load 24/7.You can disable turbo and reduce power consumption (turbo ups the voltage by a fair margin).
Electric kitchen, air conditioner, those things monthly multiply any cpu "tdp" consumption in the range of 100's.
