2 Technology and components This chapter details the technology and components available in the system. Topics: • • • • • • Processor DDR4 USB features USB Type-C HDMI 2.0 Advantages of DisplayPort over USB Type-C Processor NOTE: Processor numbers are not a measure of performance. Processor availability is subject to change and may vary by region/country. Table 1. 9th Generation Intel Core Processor specifications Type UMA Graphics lntel Core Processor i3 - 9300 (4 Cores/8MB/4T/up to 4.
DDR4 DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512 GB in capacity, compared to the DDR3's maximum of 128 GB per DIMM. DDR4 synchronous dynamic random-access memory is keyed differently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the system. DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate.
Memory Errors Memory errors on the system display the new ON-FLASH-FLASH or ON-FLASH-ON failure code. If all memory fails, the LCD does not turn on. Troubleshoot for possible memory failure by trying known good memory modules in the memory connectors on the bottom of the system or under the keyboard, as in some portable systems. NOTE: The DDR4 memory is imbedded in board and not a replaceable DIMM as shown and referred. USB features Universal Serial Bus, or USB, was introduced in 1996.
With today's ever increasing demands placed on data transfers with high-definition video content, terabyte storage devices, high megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps theoretical maximum throughput, making data transfer at around 320 Mbps (40 MB/s) — the actual real-world maximum. Similarly, USB 3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps.
Alternate Mode USB Type-C is a new connector standard that is very small. It is about a third the size of an old USB Type-A plug. This is a single connector standard that every device should be able to use.
3. DisplayPort 1.4 – compatible with existing DisplayPort monitors, devices and cables 4. USB Power Delivery - Up to 130W on supported computers Key Features of Thunderbolt 3 over USB Type-C 1. 2. 3. 4. 5.
• • HDMI combines video and multichannel audio into a single cable, eliminating the cost, complexity, and confusion of multiple cables currently used in A/V systems HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality Advantages of DisplayPort over USB Type-C • • • • • 14 Full DisplayPort audio/video (A/V) performance (up to 4K at 60Hz) Reversible plug orientation and cable direction Backwards compatibility to VGA, DVI with adaptors SuperSpe
