After the last "Tick" Intel is now at the beginning of the next "tock" carried out step. Is well known from Intel in exchange "Tock" steps, the micro-architecture of the CPU's to speed up technical innovation, the processors further. The new architecture codenamed "Sandy Bridge". We may draw two copies of the new processors with us in the newsroom a test. First, the new top model Core i7-2600K and the other is the new mainstream flagship Core i5-2500K with integrated graphics unit. Everything on the new socket 1155.
The Sandy Bridge architecture
Like its predecessor, codenamed Westmere, based on the Nehalem architecture, the new 32nm Sandy Bridge processors in the proven methods are made. Intel launches new processors for the time being not in the Extreme Edition. It requires all desktop processors introduced today the new socket 1155th This has only one pin less than the old socket 1156, but is not compatible, as a special notch which uses the old processor prevents the new socket. A successor for the high-end processors based on the 1366 base with triple channel memory interface is currently not scheduled and is expected before the second half of 2011 see the light of the world. The new processors come with 4 cores in the Core i7 Hyper-Threading enabled, so are the operating system 8 cores "faked". With the i5 Core CPU's hyperthreading is disabled it. The DDR3 memory interface has been increased to 1333. The "Die", then the processor without being documented package, now with 995 million transistors on an area of 214 square mm. Here already the graphics processor and 8 MB of L3 cache are included. When the cache has not changed in size, the L2 cache and the L1 cache still have 256 or 32 Kbytes.
The new processors are only available with the Intel chipsets of the 6th Generation compatible, in particular, these are the H67, P67, Q65, Q67 and B65 chipsets. Only the H67 chip set offers the possibility of a possibly lead to existing graphics in the CPU unit to the outside and thus to dispense with a dedicated graphics card.
Architecture
Intel takes on not only the 4 processor cores and the GPU below but also the memory controller, a PCIe x16 Rootcomplex DMI2 and control, to connect the chipset (Platform Controller Hub - PCH). All mentioned components communicate via a permit on the integrated ring bus for communication with low latency. The capabilities of the cores, Intel has a AVX (Advanced Vector Extensions) extends command unit. AVX represents the successor of SSE4 and now commands a width of 256 bits. Which were introduced with the Harpertown CPUs Arrandale or AES-NI command expansion has now almost the entire lineup put aside. AES-NI offers the ability to perform AES encryption in hardware. This will accelerate as the encrypt a ZIP archive dramatically. Finally, the graphics processor on the is the have changed considerably, This is a development of the fifth generation of Intel's IGPs and is the sixth generation.
The integrated graphics processor also allows hardware-based decoding and en-H.264 and MPEG2 video. The video playback is therefore greatly accelerated. Certain types of post were cast in silicon, so there is now an automatic contrast adjustment and a skin tone detection to correction. The signals are passed internally to the display port protocol of the PCH, from where they are spent on the integrated graphics ports. So now, a HDMI port is 1.4 with 3D capabilities possible. The GPU is DirectX 10.1 and OpenGL 3.0 compatible.
2.0 Turbo Mode
Sandy Bridge will also include a revised Intel Turbo Mode. The biggest news may be that Intel briefly about the TDP-defined budget goes. This is justified by the physical inertia of the particles. The needs of a certain moment, until it heats up. Once this is done, the Turbo lowered. The bottom line is compared to the old models for a short time a little bit more processing power available. The maximum frequency is the Turbo Core Core i7-2600K at 3.8 GHz and 3.7 GHz Core i5-2500K. Even the integrated graphics chip can increase their individual frequency in compliance with the maximum values of up to 1350MHz. The processors with a K in the name were in connection with the P67 chipset fully unlocked, and so all parameters can influence the turbo mode to be set free. In conjunction with the H67 chipset also of the parameters for the IGP are optional. The turbo mode is reserved to the Core i3 models. Of course in Sandy Bridge are the proven Intel technologies such as virtualization extensions, or the interest to business customers vPro extension. Here are the new desktop models at a glance:
