The "fourth-generation Core processor" for desktop computers, led by the Core i7-4770K, is on sale. "Haswell" (development code name) according to Intel's Tucker model order as "Tucker", the manufacturing process remains the same, is committed to improving the architecture of a generation of products. This time, we got the Core i7-4770K and the Intel DZ87KLT-75K motherboard, and we tried to verify the strength of Haswell.
Core i7-4770K is LGA1150, supporting chipset is 8 series
When Haswell is homemade, it is important to keep in mind the changes to the socket. So far, LGA1155 has been used in Sandy Bridge, Ivy Bridge, and Generation 2, but has been changed to the new socket "LGA1150" in Haswell. Of course, the two sockets are not compatible, and if the number of pins is different, the position of the incision on the CPU side is also different. The cost of upgrading to Haswell will be the CPU+ motherboard.

As mentioned above, the core i7-4770K is the same as the core i7-3770K, using a 22nm 3D Tri-Gate transistor. The working clock is set to 3.9GHz when the working clock is rated at 3.5GHz,Turbo Boost. In other words, the clock is the same as the core i7-3770K in specification. In addition, the shared L3 cache is 8m bytes, and the clock of the supported DDR3 memory reaches 1600 MHz. There are many common parts in the specification.

On the other hand, the difference is TDP. The core i7-3770K is 77 watts, while the core i7-4770K is 84 watts. Although there is a slight increase, in Ivy Bridge such as Core i7-3770K, the TDP is only 75 watts, but this may be more important considering that the required cooling performance is equivalent to 95 watts. The cooling performance required for Haswell is not clear.
In addition, integrated graphics capabilities will also change. Compared with Intel HD4000 of Core i7-3770K, Core i7-4770K is Intel HD4600. The number of EU has increased from 16 seats in Core i7-3770K to 20 seats. In conjunction with this, the DirectX 11.1 correspondence is also the focus.
Although you can't see it from the outside, when you look at CPU information in CPU-Z, etc., the place where the internal commands correspond to AVX2 is new. In addition, memory continues to support dual-channel DDR3-1600. In addition, the chipset combined with Haswell is 8 series. The motherboard "DZ87KLT-75K" included in this evaluation kit is equipped with the Intel Z87 Express chipset.
大きなヒートシンクに各種のオンボード機能を備え、ハイエンド向け製品とみられるIntel DZ87KLT-75K。マザーボードとしての「見た目」は従来同様だが、Intelのマザーボードとして見るとスッキリした印象だFrom this DZ87KLT-75K, we can see that the characteristic of the Intel Z87 chipset is that the Serial ATA3.0 is amplified to 6 ports. Before the Intel Z77 chipset, Serial ATA3.0 was 2 ports, and the other 4 ports were Serial ATA2.0, but eventually all ports became Serial ATA3.0. But in AMD's chipset, the SB85 combined as AMD890GX corresponds to the 6-port Serial ATA3.0, so it takes three years to catch up.
PCI Express x16 slots, like Intel Z77Express, can be used as 16 channels in 3.0or 8 channels divided into 3.0x2 channels. The third x16 slot in the DZ87KLT-75K is the four lanes of 2.0. In addition, there are 3 x1 slots and 1 PCI slot, as well as PCIe Mini Card slot and mSATA slot.
DZ87KLT-75K interface, 2-port gigabit LAN,IEEE1394a, and Thunderbolt, quite substantial content. The rear panel is lined with 6-port USB3.0, 2-port USB2.0, BIOS entry switch, and so on. The display output is equipped with Mini DisplayPort for both HDMI and Thunderbolt.
Serial ATA 3.0は計8ポートで、うち青い6ポートがチップセットの機能。2ポートのグレーの追加SATAのうち1ポートはmSATA用（写真＝左）。かなり充実したバックパネルインタフェース。チップセットではレガシーフリー化を進めるIntelだが、マザーボードにはPS／2やPCI拡張スロットを搭載したり、徐々に存在感の薄れてきたIEEE1394aを搭載するなど面白い。ゲーマーやアップグレードユーザー、ビデオ編集ユーザーのニーズはきちんと汲んでいるというところ（写真＝右）There are 4 memory slots, the same as before. In addition to supporting DDR3-1600 amp 1333, it is also considered to support DDR3-2400 + under superclock. In addition to the usual 1.5V, the voltage of the memory also supports 1.65V and 1.35V of low voltage used in OC.
In Haswell, the requirements and specifications for the power supply will also change. Mainly in the power-saving function of C6, C7 state, the output of 0.05 ampere is required, and the power supply also needs to meet this point. In this regard, if it is a relatively new power supply of the 80PLUS Platinum/Gold generation, it seems to be manageable, please confirm the support list of each power unit manufacturer for details.
In the Xseries XP "SS-1000XP" of Seasonic, the agent Altek sends out a broadcast and is considered to be the corresponding product. And there was no problem in the verification.
