    Phoronix: Intel Core i7 970 Gulftown On Linux

    Intel will be introducing their first Sandy Bridge CPUs in the coming months, which we already know has Linux graphics support well underway, but for now the top-end Intel desktop processors are the Gulftown CPUs that were introduced earlier this year. The Gulftown CPUs boast six physical processing cores with Hyper Threading to put the total thread count per CPU at 12. Besides putting 12 processing threads at your disposal, these CPUs are built upon the 32nm die shrink of Nehalem and boast 12MB of L3 cache. The first Gulftown desktop product to launch was the Intel Core i7 980X, which was quickly followed by the Core i7 970, and we now finally have the chance to test out this incredibly fast but expensive processor under Linux.

    Let's rice it up a bit... there.

      With the TTSIOD 3D phong renderer, which is actually all CPU-based, the Core i7 870 was moderately faster than the Core i7 970.
      But your graph clearly shows the 970 in the lead by 22fps?

        Whoops, swapped around 870 and 970 in that text. Fixed, thanks.

          As I've said a few times before, with Iveland + OpenBenchmarking.org there will be improvements in this area via their embeddable tables, etc.

            Don't you just love processors that are designed with the singular purpose of tricking the benchmarks?

              And as I've replied before, this would take 10 seconds to do by hand in your articles. Which is why it's reasonable to hope this gets done immediately, and not waiting for months while a complete website/graphing system is setup.

                With/without HT turned on?

                Any chance you could benchmark the 970 without HT to see the differences and work out if it's something worth using (or not)?

                  The new graphs look nice Michael. However one issue I see .. are you using "sub-pixel antialiasing" on the fonts? Personally I use greyscale, since sub-pixel looks terrible (reminiscent of HAM mode on Amigas, with its "colour fringing" side effect); look in Ubuntu's fonts preferences to see the difference.

                  Using Compiz to zoom in on the graphs, it would appear you are using some form of sub-pixel antialiasing, whereas you're using the equivalent of greyscale on the pts logo in the top right.

                  Greyscale antialiasing = much nicer.

                      Screenshots, that's why. The system you used was using subpixel antialiasing, no doubt. I assume we'll be seeing SVG graphs eventually, so we'll see them rendered with our own display/font settings?

                      It's a pet erm, not exactly peeve, but something like that, of mine .. to see screenshots from LCD screens. People always using that ghastly subpixel antialiasing. I don't see how people can think it looks good!

                        Well, subpixel hinting was also the first thing i noticed in new
                        graphs (which, btw, look just beautiful), and I think it's way better
                        than that blurry font rendering on previous graphs. However, there are
                        camps... as always. Apparently, it boils down to the way you are
                        accustomed to.

                        Mac people love it the way previous graph were, which I think is
                        hideous. Some Windows folks love it with jagged lines, no antialiasing,
                        "put-a-black-pixel-or-go-away" kind of rendering. It's more tolerable,
                        but not quite as nice as subpixel hinting.

                        And then, there are many kind of subpixel hinting. Original Cleartype
                        is crystal clear, but deforming font shapes. New Cleartype (WPF -
                        Vista, 7) is blurrier, but significantly better. Ubuntu sub is too
                        aggresive (you can sometimes see that on the letter 'k'), in a way
                        much like original Cleartype but lousier.

                        Finaly, there are my settings Slight hinting, David Turners patch
                        (only vertical hinting, like this), non-patented freetype hinter.
                        "These are the best settings" - Clavko said. Your mileage can vary

                          The problem with these super-expensive processors is that their value isn't that great. Sure it has lots of performance, but you can buy CPUs 3-3,5x cheaper that aren't 3-3,5x slower. Too bad there's no AMD 6-core in there as well.

                            That's right, I was looking for 6-core AMD CPUs >3GHz in this benchmark, too.

                              If only AMD sent out such CPUs to me...
