    That's only for the CPU tests. If you look at the system table on the graphics result file you see the HD Graphics were used.

      Um, I am not really familiar with the intel CPU governors but:



      Is that a fair comparison between performance and ondemand driven CPUs/APUs?

      PS: Wahoo! My 686th post. Did I win a CPU now?
      Intel CPUs on modern kernels use P-State driver where AMD CPUs don't have this driver but still use CPUfreq. The defaults were used through all of testing.

        I see 4 core streamroller based opterons coming out 1H 2014, what are you seeing? http://www.amd.com/us/press-releases...013june18.aspx

        Btw, Intel is also still 1 or 2 generations behind on Xeon chips as well. Not sure why high end server chips has to be that much behind, but it seems to be common.

            Uh.. I said that AMD was rebadging Kaveri and calling it an Opteron in my earlier post. You just completely agreed with my point and then tried to make it seem like I'm wrong... you do realize that Kaveri is a "4 core" Steamroller part? (using AMD's rather loose definition of "core") As I said, and as you just agreed with me, AMD is not coming out with high-end Steamroller parts. They don't exist. A dual-core lower-priced lower-power usage Intel part will beat those chips in the large majority of CPU benches as Phoronix showed. In the server, the IGP will be even less useful for the vast majority of real-world server workloads.

            As for Intel being "behind" their high-end server parts use Ivy Bridge cores which are behind the desktop Haswell cores. However, they give you a MASSIVE number of those cores and the power efficiency metrics are off the charts good. There's a reason that the new Mac Pro can pack a 12-core CPU into tiny wastebasket form factor.

              Well.. back in the day there was a int processor and fp co-proc. AMD really is a 4 core system based on that metric. However I think they shoot themselves for calling it that. they should say 2 module 4 threads to make sure people realize it's just a pretty darn good dual core (fp at least)

                Am I right in stating that it's going to take a while before software actually uses the real power of HSA?
                There's a ludicrous amount of GFLOPS on tap in a Kaveri APU but it needs the software to leverage it?
                I'm hoping one day I can rebuild my media server with an HSA enabled APU and get much faster transcoding than I can with traditional x86 CPUs.

                Will it ever be possible for compilers to automatically optimise the binaries to use the best Compute Core for the job based on the source code?
                Isn't that what LLVM is for?

                  It all depends on AMD. They are known for releasing the hardware with lack of proper software to support it.

                    OpenCL sw can use it right now. As for the magic compiler for C, C++, or the Aparapi Java backend, those are still in unicorn land.

                        Benchmarks are somewhat moot due to the Haswell regression. Probably would have been good to benchmark with a non-bleeding edge kernel since this is what users are mostly using anyway.

The only article doing this comparison even on Windows was one from SemiAccurate that shows A8 7600 @45W has 80% of the perfromance of A10 7850K @95W in most tests. That would make it quite competitive against an i3, especialy since most tasks you'll do on a HTPC should be acceleratable by the GPU.
                          Thanks for the link. I'll go read it later.

                          From this Phoronix article, the A10-7850K loses or just keeps up with a 54 W Haswell i3 while other tests show it's comparable to an i5. 80% of that isn't going to make things better. Of course, I need to figure out how it translates to what I plan on doing. I started clicking on the Open Benchmark links to see what these tests do but I'm still having a hard time due to some descriptions being too vague for people like me who are unfamiliar with such software. I plan on making a mini-ITX PC that replaces a micro-ATX one. Right now, the current PC not just acts as an HTPC but as a NAS, video transcoder (HandBrakeCLI since I'm not a video expert), archives/backs up data in .tar.xz that currently can take a pretty long time (I use Pixz because it support multi-threaded decompression), backs up stuff to Amazon S3 (aws-cli) and runs a VMware VM or 2. Of course, all of these aren't likely to run at the same time but several of them can be.

                          I don't keep up much with CPU performance until I plan on upgrading but so far, I may get more bang for my buck with an Intel chip. Do you know how much an A8-7600 chip is going to cost?

                            Looks like AnandTech added or I missed the A8-7600 chip. The MSRP is $119 so maybe it'll be less than that in actual retail. I'll start looking into the cost of mini-ITX boards to see what the total system price differences are between a Haswell and Kaveri. I hear AMD based mini-ITX boards are rare though.

                              ASRock and Gigabyte seem to have nice FM2+ Mini-ITX mobos...
