Invincible no suspense six core Corei7-970 conquer Ubuntu10.10

Three months ago, we checked Intel's second desktop 6-core processor GulftownCorei7-970, but the testing environment was Windows, today, let's take a look at the performance of the multi-threaded capability put under the Linux system, and compare it with other different models of Intel and AMD. The Corei7-970 is manufactured with 32nm process and LGA1366 encapsulation interface. The original clock speed is 3.20 GHz, and the dynamic acceleration of TurboBoost is up to 3.46 GHz.

Three months ago, we checked Intel's second desktop six-Core processor Gulftown Core i7-970, but the test environment was Windows, today, let's take a look at the performance of the multi-threaded capability put under the Linux system, and compare it with other different models of Intel and AMD.

Core i7-970 is manufactured using 32nm process, LGA1366 encapsulation interface, original clock speed 3.20 GHz, Turbo Boost dynamic acceleration up to 3.46 GHz, non-Core frequency 2.66 GHz, QPI bus frequency 4.8GT/s, level 3 cache 12 MB, thermal design Power Consumption 130 W, official thousands of wholesale price 885 USD.

Compared with the previous flagship ultimate version of the Core i7-980X Extreme, the new six-Core clock speed reduced by 133 MHz, QPI bus frequency also reduced by 1.6GT/s, and lock the frequency doubling, but other specifications are basically unchanged, the price is 114 US dollars cheaper.

Platform configuration for testing with Core i7-970 includesHuawei X58 SuperComputer Motherboard, CSX DDR3-1600 3 GB memory, OCZ Vertex 64 gb ssd, GeForce GTX 460 graphics card and so on. After the Ubuntu 10.10 64-bit version is completely installed, the system starts smoothly. By the way, the BIOS is updated to the latest version 12th day of this month, which was just released on April 9, 3.30.

Apart from the lack of temperature monitoring software LM_Sensors, another major problem with this system isManual overclock failure. Even if you increase the frequency to 3.5 GHz, or use the BIOS overclock option, the system will restart quickly, or the Linux kernel will crash.

The processor involved in the comparison and the matched motherboard include:

-Core i3-530, Clarkdale, dual-core, four threads, clock speed2.93 GHzElite H57H-M

-Core i5-750, Lynnfield, four core and four threads, clock speed2.66 GHzElite P55H-A

-Core i7-870, Lynnfield, four-core eight-thread, clock speed2.66 GHz, Dynamic acceleration up to 3.60 GHz; elite P55H-A

-Core i7-920, Bloomfield, four-core eight-thread, clock speed2.66 GHz, Dynamic acceleration up to 2.93 GHz; Huayu X58 SuperComputer

-Phenom II X3 710, Heka, three cores, three threads, clock speed2.60 GHz,Testing exceeds 2.70 GHz; MSI 890GXM-G65

-Opteron 2384 × 2, Shanghai, dual-channel workstation, eight core eight threads in total, clock speed2.70HzTai'an Thunder n3600M

In the test, if the Intel processor supports Turbo Boost dynamic acceleration, it will be enabled.But because the memory controller is different, Core i7-970/920 all use three-channel 3 GB, others are dual-channel 4 GB. Keep the default Operating System configurations. The graphics card driver version is 260.19.0.
