The standard ATX Intel DZ77GA-70K, which is compatible with socket 1155LGA processors, supports a number of high-speed interfaces such as PCI Express 3.0, SATA 3.0, USB 3.0 and some advanced capabilities. Responsiveness, availability of the system.
Intel DZ77GA-70K motherboard (BMC) is based on the Panther Point Z77 chipset platform. The ATX standard size, supporting socket 1155LGA, is compatible with both Sandy Bridge and Ivy Bridge processors.
On the right is the Ivy Bridge Core i7-3770K (3.5GHz, 8MB L3 cache), third generation of 22nm processors with 22nm technology and 3D transistors. On the left is a Sandy Bridge Core i7-2600K (3.4GHz, 8MB L3 cache) processor that utilizes 32nm manufacturing technology with second generation Hi-K metal gate transistors.
Both Ivy Bridge and Sandy Bridge processors use the Sandy Bridge microarchitecture. Intel still maintains socket 1155LGA with Sandy Bridge so both can work well on the 6-Series (Cougar Point) and 7-Series (Panther Point) motherboards.
In addition to the SATA 3 interface (or SATA 6Gbps), the 7-Series (Panther Point) BMC chipset supports a number of high-speed interfaces, such as PCI Express 3.0, USB 3.0, Thunderbolt interface, and some other technologies. Quick responses such as Smart Response, Rapid Start, and Smart Connect improve responsiveness and system availability.
The BMC supports both ATI CrossFireX and NVIDIA SLI technology with two PCIe x16 slots (one PCIe x16 3.0, one PCI x16 2.0) and PCIe shared bandwidth managed by the processor.
In addition, BMC has an additional PCIe x4 and two PCIe x1 slots with expansion cards and some relatively old PCI slots that are still in widespread use.
Port numbers are quite comprehensive, including 4 SATA 3.0 and 4 SATA 2.0 RAID support 0/1/5/10.
Back panel with 1 PS / 2 mouse or keyboard, 1 eSATA 3.0, 4 USB 3.0, 4 USB 2.0, 1 IEEE 1394a, 2 1Gbps Ethernet port, HDMI video output, 7.1 HD audio and Back to BIOS button.
In addition, BMC’s extensive communication numbers (with optional accessories) include four USB 3.0, four USB 2.0, and one IEEE 1394a. Power buttons and reset buttons are also included on the BMC.

To evaluate the Intel DZ77GA-70K BMC performance, Test Lab uses a test configuration built on the Ivy Bridge platform, Windows 7 Ultimate 64 bit SP1, and uses the BMC driver. Performance evaluation tools include CineBench R11.5 (64 bit), Heaven Benchmark v3.0, 3DMark 11 and PCMark 7. During testing, BMC works with default NSX settings and the test to get the average result after 3 runs.
With PCMark 7, the overall system performance evaluation tool. Test configuration reached 3,938 points; It is about 2% – 5% higher than some Z77 BMC chipsets in the same test at Test Lab.
Similar to the Cinebench R11.5 (64 bit), the test configuration scored 7.91 points on the CPU test and 84.29 fps on the OpenGL test.
In testing the DirectX 11 multi-threaded graphics platform based on the 3DMark 11 engine, performance settings were set at 7,405 points, about 1% lower than the BMC MSI Z77A-GD80 (7,462 points).
With the Heaven Benchmark, a graphics tester has a lot of similarities with 3DMark 11 but mainly for Tessellation performance (DirectX 11), test configuration is 1,608 and 63,8 fps.
– Overall performance is higher than the average of the test BMCs.
– Support port number is quite adequate.
– Only supports HDMI video output.
