    Phoronix: Intel Core i7 3770K Ivy Bridge Linux Performance

    Intel is finally announcing the first Ivy Bridge processors this morning. I have been extensively testing out the Intel Core i7 3770K, the current high-end Ivy Bridge processor, for the past few weeks under Ubuntu Linux. I have been extremely pleased with the Intel Core i7 Ivy Bridge processor under Linux with its phenomenal performance, power efficiency, and new features. This article is the first of many looking at the Linux performance of the new Intel Ivy Bridge processors.

    Excellent and extensive Michael - I'm looking forward to the graphics benchmarks!

    Thank you!

      The graphics article will be up in 2~3 hours. My battery is dieing and I still have about an hour en route to Seattle so once I'm on the ground and find a Starbucks I'll get to posting that.

        Maybe it's better that way, the server can't stand for more load right now
        ## VGA ##
        AMD: X1950XTX, HD3870, HD5870
        Intel: GMA45, HD3000 (Core i5 2500K)

          What's up with all the Intel marketing slides (4 pages or so!), and why so much praise in this article? It's just a CPU, of course it's going to work well with Linux. And for most people modern CPUs have reached levels of performance that they don't really care about that anymore.

            wow I never realized bulldozer was so good just goes to show you windows and application code is just optimized for intel. Bulldozer was within usually 30% of ivy ridge with march native, pile driver is supposed to be a 25% improvement closing the gap significantly. Coupled with better graphics I'd say AMD is killing intel (at least on source linux distros) I can't wait to get a trinity notebook and install gentoo

              The selection of cpus to compare just miss one: i7-2600K or better i7-2700K (or i7-2600K @ i7-2700K clock speed). When you compare against i7-2700K it would be a 4% gain and against i7-2600 about 10%. It is not really good when you compare only against i5-2500K as that cpu has got no HT enabled. K cpus should be really easy to OC, other cpus can only raise the turbo multis +4 and a bit bclk. I would like to benchmark my i7-3770S but my board died - all i did was changing the boot order. (It was running at stock speeds, nothing oc.) One other aspect: the power usage was only tested together with a dedicated gfx card, that should be tested without for all cpus with integrated gfx core as well. Btw. it is also possible to OC the graphics core, my i7-3770S was set at 1150 by default, 1350 was possible without extra voltage, 1450 with 0.2v more. max clocks for my cpu have been 105.2*40 (40 only used for 3-1 core at full speed) without extra voltage, with 0.2v more i could use the full 105.2*43 (still only 39 for 4 cores the same time). But my cpu cooler was not good enough for permanent oc with extra voltage. One interesting aspect is when you set just the turbo modes for 4,3 and 2 cores active to the maximum you gain already a bit speed, but that resulted in +10C more heat (on full load) with my AC Freezer 7 Pro v2. So better use something bigger

                A disappointment, as expected. If it wasn't labeled, you couldn't tell Ivy Bridge apart from its predecessor. Same IPC rate, same power consumption. Better graphics, maybe, but I never use that.

                  Intel should really start making discrete GPUs. I'm sick and tired of waiting on AMD and especially Nvidia for their extremely sluggish, maimed, or nonexistent FOSS driver support.

                    The comparison was limited to the other CPUs available...

                      and this is naming the fact that this linux software is not even optimized for AVX/FMA/XOR and the other goodies in bulldozer, maybe for average joe wannabe "expert" is "slower than sb dude why waste money?" but for us is geek candy on the cheap.

                      for the smart mouths FMA and XOR really make huge diff if used properly and your cache is sane and remember that AVX can process 4 double(very rare is most workloads) or 8 floats(very common). in my case i modified my old SSE idct[Mx'M] code to use avx and FMA and loop it to run 1 million times and is around 35/45% faster in the same bulldozer cpu, so bd have a lot of juice to extract yet.

                      bd problem is most software outhere is poorly threaded and/or with crappy cache management and/or barely uses SIMD at all(this applies to SB too though)

                        I just hope that the Catalyst drivers will work fine with Linux. Do you expect any problems with the drivers under Linux?

                          Catalyst should already work with Trinity.

                            Without SB 2700K this comparison just doesn't make sense, because IB 3770K is its direct competitor in terms of price and CPU features (HT & frequency).

                              I'm excited to see how the Piledriver and Trinity CPUs work out against this!
